Scientists are very serious.

This is a post about science. And soup.

Dr. Elinne Becket, a microbiologist from Cal State University, is in the middle of one of those Fridge Experiments that happens to us all - except in this case, she is uniquely placed to unravel the science down to the microbial level.

While cleaning out her fridge, Dr. Becket found that a tub of family-recipe beef vegetable soup had turned bright blue. “Ok I'm outing myself here,” she tweeted, “but there was forgotten beef soup in our fridge we just cleaned it out and it was BLUE?!?!? Wtf contam would make it blue??? Like BRIGHT blue!!  Even w/ all my years in micro I'm not handling this well.“

Read on for a breathless and ongoing saga of Soup and Science, and the wonderful international community that is Academic Twitter.

Academic Twitter quickly reminded her of her Responsibilities to Scientific Inquiry. (Cue the chanting from around the world of “CLONE THE SOUP! CLONE THE SOUP!”)

“I can’t believe y’all talked me into going back into the trash.” she tweeted in response, over a photo of a puddle of beautiful Mediterranean-sea blue soup in the trash bin, with bits of veg and noodles arising from the depths.

Scientists being scientists, Dr. Becket agreed to take a sample and send it to colleagues for cloning and microbial analysis.This involved getting arms-deep into the trash bin of Old Soup. “I’m never forviging @ATinyGreenCell (genomic biologist Sebastian Cocioba) for this.” Dr. Becket tweeted, with a photo of a properly dipped and snipped and VERY blue q-tip in a small clear plastic tub.

Diving into decomposing soup was not the only hazard. She writes: “My mom (who made the soup for my birthday) came across this thread and now 1) I have to answer for letting her soup spoil and 2) she's worried @ATinyGreenCell will figure out her secret recipe.“

Dr. Becket and Sebastian were able to culture the Blue Goo!

Becket posted a photo of three petri plates of streaked beef bouillon agar at 72 hours incubation, at 37C, room temp and 4C. She writes: “Left the plates where they were for another 2 days, except the 37°C one was brought to RT, which then grew white stuff over the yellow stuff and stinks to high heaven. RT looked the same. 4°C had impressive growth. Restreaked them all onto TECH agar, awaiting results!”

Sebastian, from his lab, tweeted a photo of three more covered petri dishes, with early results: “Great progress on isolating the glowy microbe from our #BlueSoup! It's so fluorescent the streak is GREEN. Still needs another restreak as it seems there is a straggler but should clear up in the next plate. Exciting!”

Then yesterday, Sebastian tweeted out an updated photo of his plates under daylight and blacklight. “Whatever grew on the #BlueSoup colony plates overnight glows under UV, but only on King's Agar B! That particular media is used to tease out fluorescein expression in pseudomonads. What are the chances that the same cell line expresses fluorescent AND blue pigments?“

“Looking closer, there definitely is a handful of different microbes showing distinct phenotypes. Could be that the blue producer and the fluorescent microbes are totally different microbes!”

At which point, Professor Cynthia Whitchurch of Norwich, England, responded: “Consistent with P. fluorescens being at least part of the #BlueSoup community. The fluorescence is due to production of the siderophore pyoverdine which is up-regulated when iron availability is limited. P. aeruginosa produced this too but my guess is you have blue Pf.”

And Australian agricultural researcher @WAJWebster helpfully tweeted a petri dish of ALL KINDS of colourful bacterial colonies from white to yellow to orange to stark black, with a cheerful: “You need bact-o--colours? I got you, fam.”

The best part is that as of today, March 9, 2023, THE BLUE SOUP MYSTERY CONTINUES. WE ARE WATCHING SCIENCE HAPPENING!

A paper is being written. And Dr. Becket’s mum is getting an author credit as the proprietary owner of the #BlueSoup recipe.

‎⍟༄ i don’t remember if it’s canon that peggy is tony’s godmother . . . either way, i made her his godmother here, anyway. (it was just briefly mentioned.)

It was three o’clock in the morning. Hence the time was moved rearward to accommodate the season’s daylight, it was utterly dark out still. The streets were quieter, but still quite alive with fluorescent lights coming from every establishment. True to its name, the city never actually sleeps — and, apparently, so did its best defenders.

“To what do we owe this pleasure?” Tony Stark was perhaps the only one who looked the most attentive, given that he functions well regardless of the amount of sleep he gets each night. Often times, he could be found tinkering in his lab while the rest of his team slept.

“Another body has been found in the Arctic,” Nick Fury just went straight to the point without even batting an eye. As the host, he neglected to ask whether his visitors would fancy some coffee, but he didn’t seem to care.

Natasha Romanoff was supporting her head with her hand, blinking rather fast to remove the sleepiness in her eyes. “And that concerns us how?”

“Technically, it only needs to concern me, since I was the only one formally called over,” Tony interjected, matter-of-factly. “You lot just decided to follow me.”

Sam Wilson was quick to reply, “In our defense, it was a hasty decision — and we certainly can’t make good ones without some caffeine.”

Fury caught the hint, but chose to ignore it. Instead, he immediately redirected the conversation back on the right track, “S.H.I.E.L.D. has reasons to believe that she was connected to your godmother specifically.”

He handed a manila envelope to Tony, who then placed its contents neatly on the table. They were photographs — all of which had a girl, who couldn’t be older than sixteen, lying inside a large block of ice. She looked somewhat comfortable lying there, seemingly unbothered by anything.

Her eyes were closed, as if she was merely slumbering. Her otherwise long, straight dark hair was curled by the tips and was resting neatly behind her. Her fair skin seemed to have maintained its normal pigment despite being in the ice for quite awhile. Her clothes, too, were notably from an era that already came to pass decades ago. But, above all, her facial structure uncannily resembled a prominent English agent.

“She looks like Peggy,” Steve Rogers gasped. Except for a few distinctions, there was no denying it.

“Okay,” Tony clapped his hands rather loudly, which succeeded on catching everyone’s undivided attention, “I think it’s time for that coffee break Wilson was talking about.”

Happy Preservation Week! (Part 5 :)

Hello again, and Happy Preservation Week, everyone!

This is the 5th and final installment of our Preservation Week 2021 blog series, if you missed Part 1, Part 2, Part 3 or Part 4, feel free to check them out first!

In our previous post (Part 4), I described the preservation of a set of unexposed Daguerreotype plates and the original wooden box they were issued in. For those objects, I made an (admittedly) complex preservation enclosure that will keep everything safe in storage, but it might be a little confusing to the next person who opens the box. Sometimes it’s hard to make a simple, easy to use preservation enclosure… you find yourself making a series of “simple” decisions that snowball into something complex and baffling!

In this, our final Preservation Week post, I’ll discuss a preservation enclosure that needed to fulfill a lot of different requirements, and the object that it houses is one which I never expected to find in a library! This object is part of the Outpunk Archive at NYU, which contains materials from 1989-1998 relating to Outpunk (both the zine and the queercore music label). While most of the collection consists of papers, photographs, and music recordings, there are also several T-shirts and ...a skateboard!

Apparently, a member of the Riot Grrrl movement owned and adorned this skateboard: one half of the top of the board is spray painted white, and the words “FIGHT HOMOPHOBIA” are spray painted in orange on the other half (Photo 1). Lots of stickers, self-adhesive labels and zine-style xeroxed drawings are pasted to the bottom surface of the board (Photo 2). This person probably lived in San Francisco in the late 1990’s, because one drawing asserts that “The Mission Bay Project SUCKS!” (Photo 3).

A few of the papers are bright yellow, orange or green, and these glow brightly under UV, suggesting that the papers contain daylight fluorescent pigments (Photo 4). These pigments look unusually bright in sunlight because they absorb UV radiation and reflect it back to the eye as visible light. While we were examining the top of the board under UV, we found yet another message hidden beneath the white paint... at one point, the owner of this skateboard believed that “FASHION IS A SCAM”, but she later decided to paint over this message (Photos 5-6).

So... why the heck was this skateboard in the conservation lab? Well, it’s a lot bulkier than the average library book, and since the wheels work perfectly we couldn’t just leave it on a shelf! We needed to give the skateboard a preservation enclosure to keep it from rolling around in the stacks, or being mistaken for an NYU student’s property. Most of all, we wanted to give the skateboard a preservation enclosure to prevent its minor damage from getting worse: the plywood board is cracked and splintering at one corner, the sandpapery grip tape is flaking off around the edges, and most of the stickers and drawings are torn and/or curling. We briefly discussed whether we should perform a little conservation work to stabilize these parts of the board; in the end, we decided that we didn’t want to obscure evidence of the skateboard’s use, and everything was stable enough to withstand gentle handling. ...Some may be thinking, “COME ON, it’s a skateboard! This is ridiculous.” To that I say, it’s part of an archive now! We have to treat it carefully, so it lasts a long time. :)

The library’s curators are interested in showing this skateboard during classes, and it’s possible that the object will be requested frequently in the Special Collections reading rooms. As you may recall, the main purpose of my Daguerreotype enclosure was to keep all of the components safe during storage and transit, but the skateboard’s enclosure needed to fulfill two additional requirements: it needed to be simple enough for anyone to unpack/repack easily, and because the skateboard is double-sided, the enclosure needed to function as a double-sided display mount. Under the supervision of Jessica Pace, Preventive Conservator, I created a simple preservation enclosure that would protect the skateboard and allow the curators to safely display either side.

We started by ordering a custom archival box with a drop-wall, which allows you to remove a bulky object more easily (Photo 7). Because the skateboard is a bit heavy and awkward, I also made a handling tray from cross-laminated sheets of archival corrugated cardboard. This tray (Photo 8) allows you to pull the skateboard out of the box, rather than lifting it. I also adhered strips of corrugated board to the bottom of the tray which adds a little more rigidity and allows for air-flow underneath when the tray is pulled out of the box. We decided it was best to store the skateboard wheels-down, so we had to find a way to prevent it from moving around in the box, or rolling off a table. Jessica thought it would be easiest to create bumpers on either side of the wheels, so I experimented with pieces of “Ethafoam” (low-density polyethylene foam, Photo 7). I cut four narrow strips of Ethafoam, and I wrapped them in a sheet of Tyvek fabric to prevent the foam from shedding bits of plastic inside the box. I used low-melt glue to adhere the foam to the handling tray, and I attached a pair of cotton pull-tabs to either side of the tray, to help people remove it from the box. The foam bumpers not only keep the skateboard stationary, but they can function as a display mount when someone wants to see the underside of the board. You can see the final enclosure in Photos 9-10, below:

Again, this was purely a preservation treatment, because the skateboard is in fairly good condition, despite minor damage. We chose not to repair this damage because it reflects the owner’s use of the skateboard, and the damage is not yet severe enough to threaten the object’s structural integrity. This simple preservation enclosure will prolong the life of the object and allow for conservation treatment in the future, if that becomes necessary. It may seem a little strange to treat this 20-year-old skateboard as though it were an ancient relic! I’ll admit, there were times when it felt a little absurd to apply my book and paper conservation skills to an object that (on the surface) looks like nothing special. If all goes well, however, the skateboard will survive for as long as the Daguerreotype plates or the 16th century parchment book... if so, the skateboard will teach future generations about late 20th century feminism and politics, queer history, punk rock, and alternative transportation!

Thank you so much for reading about our preservation activities at NYU Libraries this week, and thank you for supporting your local libraries!

Happy Preservation Week,

-Cat Stephens

What safety vest is right for your worksite?

Before going ahead with the choice of the right safety vest for the working conditions, it becomes essential for understanding the difference between day and night safety.

Besides, it can also give the opportunity of acting in the form of personal protective equipment. That said, the high visibility vest turns out to be the most important for the workers for operating around the moving machinery as well as a vehicle. They are important in the areas like the Shipyard, warehouses, airports, railroad construction, and the traffic control site.

Availability of the day safety vests

You can get the availability of resources and nature of the safety vests to make sure that the special pigment in the material will be working to capture and reflect the ultraviolet light. It works to capture the sun's rays for making the vest gets illuminated that will be standing out from the surroundings. Besides, there a possibility of the class D garments that will be containing fluorescent and some non-retroreflective material. It will be working only during the day.

The speciality is that class D best turns out to be unsafe for wearing outside in the daylight hours. Especially in Dawn and Dusk, the sky is devoid of the UV rays, and so it doesn't become likely for the garment to reflect light. This is the reason why the workplaces always need a vest more than just the brightly coloured material for standing out from the background. This is where there's a requirement of the day of the night vest comes into the role.

The classy day and night (D/N) garments come across with a combination of fluorescent materials and will be effective enough in terms of illumination. They find immense importance in the night time. This is something that will be given convenience both during the day and the night. The most favourable option is that a reflective strip of the material can always reflect the light from the light sources like the vehicle headlights to make the wearer more visible to the things around them.

Always follow the washing techniques while complying with the manufacturer's instructions. Keep examining the garments periodically for damage or degraded portions. Also, go ahead with replacement whenever necessary.

Embroidery standards

It's good to note that the Hi vis vests manufacturer also has in-house embroidery services that will be making sure of customising the vest according to the name of the workplace. Getting the vest embroidered with the event, logo, name, location, project, and other such entities is good for making sure that it will be standing out on the site and looking cohesive.

Impact of wearing such high vis clothing

Visibility turns out to be the major concern when it comes to job wear. There is always the moving machinery surrounding you. That said, the highway construction or also the warehouse positions always require such vests for the low visibility work environment. The Hi vis clothing guidelines also suggest being equipped with high visibility clothing. This can make sure that you will stay safe even in dreadful conditions. High visibility clothing is good enough for making the employees look visible even in low light conditions. Then you get high visibility workwear that turns out to be quite visible and more noticeable in the work environment.

With us, you can get the availability of the high visibility apparel that turns out to be part of the personal protective equipment and the work environment. It complies with the recent compliant standards in the country.

People who will be requiring the high visibility clothing

Type 1

Type 1 falls under class 1 Hi vis workwear and requires that for off-road usage in the industries. The workers always require such apparels in the service location, workers warehousing location, along with the gas extraction workers. The refinery workers and the mining workers also require such clothing.

It comes with around 217 square inches of the background fabric with the class 3 workwear that is good for anyone who is working for the department of transportation. Even the municipality workers will need these. The overall appearance of the highest standard work wear that comes with the required features and the background fluorescent material also stand out.

Type R

Class 2 level 2 is around 540/775 grade and is good in terms of the background fabric that comes with 201 square inches of the reflective design.

Type P

This is the Workwear Melbourne type that comes with public safety as well as the type R. It comes with the 2 50 square inside the background fabric along with the 201 square inches of the reflective design. Overall it comes with a background fabric with 310 square inches and a reflective 2.0 inches wide design. There are also compliant standards that can make sure that the high visibility will be complying with the workplace requirements.

Sometimes it happens so that the employers are mistaken that the apparel is high visibility due to the colour of the type fluorescent Yellow or the green, fluorescent orange, and similar other fluorescent colours. But it is not always the same. You should always consider going ahead with the proper design of the high vis clothing while also making sure that it is ANSI certified. Reflective tape can make sure of working out in the zones that require safety.

Dynamic tattoos promise to warn wearers of health threats

Within the not-too-distant future, tattoos might change into medical diagnostic units in addition to physique artwork. LightFieldStudios/iStock through Getty Pictures

Within the sci-fi novel “The Diamond Age” by Neal Stephenson, physique artwork has developed into “continuously shifting mediatronic tattoos” – in-skin shows powered by nanotech robopigments. Within the 25 years for the reason that novel was revealed, nanotechnology has had time to catch up, and the sci-fi imaginative and prescient of dynamic tattoos is beginning to change into a actuality.

The primary examples of color-changing nanotech tattoos have been developed over the previous few years, and so they’re not only for physique artwork. They’ve a biomedical objective. Think about a tattoo that alerts you to a well being drawback signaled by a change in your biochemistry, or to radiation publicity that may very well be harmful to your well being.

You possibly can’t stroll into a physician’s workplace and get a dynamic tattoo but, however they’re on the best way. Early proof-of-concept research present convincing proof that tattoos will be engineered, not solely to vary shade, however to sense and convey biomedical info, together with the onset of most cancers.

Signaling biochemical adjustments

In 2017, researchers tattooed pigskin, which had been faraway from the pig, with molecular biosensors that use shade to point sodium, glucose or pH ranges within the pores and skin’s fluids.

In 2019, a workforce of researchers expanded on that research to incorporate protein sensing and developed smartphone readouts for the tattoos. This yr, additionally they confirmed that electrolyte ranges may very well be detected with fluorescent tattoo sensors.

In 2018, a workforce of biologists developed a tattoo fabricated from engineered pores and skin cells that darken after they sense an imbalance of calcium attributable to sure cancers. They demonstrated the cancer-detecting tattoo in residing mice.

UV radiation sensors

My lab is taking a look at tech tattoos from a unique angle. We’re focused on sensing exterior harms, akin to ultraviolet radiation. UV publicity in daylight and tanning beds is the primary threat issue for all sorts of pores and skin most cancers. Nonmelanoma pores and skin cancers are the most typical malignancies within the U.S., Australia and Europe.

UV-activated tattoo ink is invisible till uncovered to UV mild. Jesse Butterfield/The Laboratory for Emergent Nanomaterials, College of Colorado Boulder, CC BY-NC-ND

To assist handle this drawback, we developed an invisible tattoo ink that turns blue solely in UV mild, alerting you when your pores and skin wants safety. The tattoo ink accommodates a UV-activated dye within a plastic nanocapsule lower than a micron in diameter – or thousandth of a millimeter – about the identical dimension as an abnormal tattoo pigment.

The nanocapsule is required to make the color-changing tattoo particles massive sufficient. If tattoo pigments are too small, the immune system quickly clears them from the pores and skin and the tattoo disappears. They’re implanted utilizing tattoo machines in the identical method as common tattoos, however they final for under a number of months earlier than they begin to degrade from UV publicity and different pure processes and fade, requiring a “booster” tattoo.

I served as the primary human take a look at topic for these tattoos. I created “photo voltaic freckles” on my forearm – invisible spots that turned blue underneath UV publicity and jogged my memory when to put on sunscreen. My lab can also be engaged on invisible UV-protective tattoos that may soak up UV mild penetrating via the pores and skin, like a long-lasting sunscreen just under the floor. We’re additionally engaged on “thermometer” tattoos utilizing temperature-sensitive inks. Finally, we consider tattoo inks may very well be used to stop and diagnose illness.

On this TEDx discuss, the writer demonstrates the UV-detecting tattoo.

Momentary high-tech tattoos

Momentary switch tattoos are additionally present process a high-tech revolution. Wearable digital tattoos that may sense electrophysiological alerts like coronary heart charge and mind exercise or monitor hydration and glucose ranges from sweat are underneath growth. They’ll even be used for controlling cell units, for instance shuffling a music playlist on the contact of a tattoo, or for luminescent physique artwork that lights up the pores and skin.

The benefit of those wearable tattoos is that they’ll use battery-powered electronics. The drawback is that they’re much much less everlasting and cozy than conventional tattoos. Likewise, digital units that go beneath the pores and skin are being developed by scientists, designers and biohackers alike, however they require invasive surgical procedures for implantation.

Tattoos injected into the pores and skin provide the most effective of each worlds: minimally invasive, but everlasting and cozy. New needle-free tattooing strategies that fireside microscopic ink droplets into the pores and skin are actually in growth. As soon as perfected they are going to make tattooing faster and fewer painful.

Prepared for on a regular basis use?

The colour-changing tattoos in growth are additionally going to open the door to a brand new type of dynamic physique artwork. Now that tattoo colours will be modified by an electromagnetic sign, you’ll quickly be capable to “program” your tattoo’s design, or swap it on and off. You possibly can proudly show your neck tattoo on the motorbike rally and nonetheless have clear pores and skin within the courtroom.

As researchers develop dynamic tattoos, they’ll want to check the protection of the high-tech inks. As it’s, little is thought in regards to the security of the greater than 100 totally different pigments utilized in regular tattoo inks. The U.S. Meals and Drug Administration has not exercised regulatory authority over tattoo pigments, citing different competing public well being priorities and an absence of proof of security issues with the pigments. So U.S. producers can put no matter they need in tattoo inks and promote them with out FDA approval.

Thus far, there isn’t a proof that tattoos trigger most cancers, and one research even discovered that black tattoos defend in opposition to UV-induced pores and skin most cancers. Nonetheless, many tattoo inks include or degrade into substances which can be identified to be hazardous, and well being issues together with an infection, allergy and granuloma have been present in about 2% of tattoos. Extra analysis is required to grasp the long-term results of nano- and microimplants within the pores and skin generally.

A wave of high-tech tattoos is slowly upwelling, and it’ll in all probability maintain rising for the foreseeable future. When it arrives, you may determine to surf or watch from the seashore. In case you do climb on board, you’ll be capable to verify your physique temperature or UV publicity by merely glancing at considered one of your tattoos.

Daylight Fluorescent Pigments  Market industry analysis and forecast 2019-2027.

 Overview

 Thermoplastic pigments (Melamine Formaldehyde Type) are clear, brittle and easily pulverized into a pigmentary form. It is one of the oldest form of carrier resins based on PTSA formaldehyde. It is used in printing inks, textile printing and paper printing to name a few. Thermoplastic pigment (Polyamide Type) is the mixture of polyester and polyamide with the melting point of 110-150o C. This type of thermoplastic Pigment is used in Plastic. Thermoplastic Pigment (Polyester Type) is the combination of polyfunctional glycols and phthalic anhydride with the melting point of around 90oC. This type is also used in Plastic Industry. The difference between Polyester type and polyamide type is that the Polyester type have lower softening points as compared to polyamide type. Thermoplastic Pigment (Vinyl or Acrylic Type) does not contain any formaldehyde and its matrix is made up of PVC or acrylic resin. This type of Thermoplastic pigment is majorly used for calendar vinyl. It does not show high color strength. Thermoset Pigment (Melamine Formaldehyde Type) is the chemical modification of the PTSA-MF resins. It has an increased solvent resistance and the softening temperature is raised to 175oC. This type is used in printing inks, Solvent based paints and PVC inks to name a few.

Quick Guide To Pantone Fluorescent Inks

Fluorescent inks are based on pigments that have the ability to absorb Ultraviolet energy and virtually immediately re-emit this energy within the visible spectrum. The effect of this is to cause the print to glow and appear very bright in daylight conditions.

When printing with Pantone Fluorescent inks, the following points should be considered:

• Fluorescent inks should be printed on white or light backgrounds, which act as a reflector base, and enhance the fluorescence.

• The level of fluorescence is proportional to the thickness of the pigment layer.

• Fluorescent pigments are semi-transparent and have lower colour strength compared to conventional pigments

• Due to the facts above, best results are achieved by applying a double layer of ink.

• Fluorescent inks have a tendency to take up more fount than conventional inks. This can lead to poor transfer and possible over emulsification. For this reason, fount solution levels should be kept to a minimum.

It should also be noted that the light fastness of these types of pigment is generally poor. Print standards should be stored away from the light to minimise any colour change.

Adequate light is the most important factor that should be considered when growing marijuana plants. Just like using nutrients made for cannabis, quality light should be well supplied to your plants to enable proper growth. 

To produce more cannabis buds, light is your secret weapon.

Using the correct wavelengths of light also ensures that the cannabis buds will be as potent as possible.

Cannabis is very light-sensitive, there is a need to adjust the light intensity, color, and frequency for each of its growth stages. This emulates the natural conditions found in nature.

This is the reason indoor growers tend to buy a full-color spectrum of lights for their plants to maximize their budding and growing abilities.

In this article, we will answer the question of how does the light color spectrum impact growing cannabis. Let’s get started already, shall we?

The Light Color Spectrum

When we see a rainbow we are amazed at the beauty of all the colors. Rainbows are formed when white light is dispersed through water vapor. This refracted light breaks up into the individual colors that make up white light. Each one of these colors in the rainbow has a wavelength.

These different wavelengths of visible light are what make up the colors we see. The visual spectrum of light contains wavelengths that range from 700nm at the red end down to 400nm at the violent edge. “nm” stands for nanometers.

The reason things have color is that an object will absorb some wavelengths of light while reflecting others.  

So for example, a green leaf will absorb all colors of light except for green. The green wavelength is reflected and we see that as color.

Black and white are not considered colors, they refer to shade and brightness. Black objects absorb all of the visible light spectra while white objects reflect it. This is why dark objects get hot faster on a sunny day, they absorb more light energy and give it off as heat.

I hope you’re still following me here. Light and color are two really interesting science topics. I encourage you to learn more about them if sciency stuff is your thing. This is a fairly basic explanation, but understanding how light and color work will help you make more informed choices when it comes to growing lights.

This chart shows what wavelengths of light chlorophyll A and B absorb from the light spectrum.

Chlorophyll A is the primary pigment used for photosynthesis. A will absorb violet-blue and orange-red light energy.

Chlorophyll B works as an accessory pigment that increases the amount of the light spectrum the plant can use as energy. It absorbs more blue light energy.

This chart shows an example of the different intensities of wavelength of the visible spectrum of daylight. Of course this will change on any given day and depend on the time of the season.

When the sun is lower in the horizon for longer periods (late summer and fall), plants receive more of the red and orange wavelengths. These colors naturally trigger a plants ability to flower and produce fruit in an attempt to propagate before the cold winter months.

How Light Color Affects the Growth of Cannabis Plants?

There are lots of grow lights on the market and each has its pros and cons. If you have taken the time to pay keen attention, you will discover that many of these lights will offer different colors of light. This can sometimes be referred to as light temperature.

Natural sunlight provides the entire light spectrum. As the year moves along and seasons change the amount of wavelength energy changes. In the summer sunlight is heavy with green and blue wavelengths, while in the fall because of the shorter days and the sun being lower in the sky, it will give off more red light. 

This change in wavelength intensity and duration is what tells plants and animals to prepare for seasonal changes. Cannabis plants are no exception.

Three Types of Common Grow Lights

Cool White CFL Bulb

A great light for young cuttings and seedlings. The cool white varieties provide lots of blue spectrum light that promote new growth. These lights put out about 50 watts of energy which is inadequate for large scale cannabis growing but great for starting plants in smaller home grows.

Blue Red LED

These common LED light arrays usually range in power output from 100 watts to 1000. They provide lots of light energy at a smaller energy footprint than more traditional grow lights. Many come with a switch that will turn on more red light LED to help promote flowering.

HPS (High Pressure Sodium)

These lights gives off plenty of red, orange, and yellow light energy. This makes them perfect to use during the flowering phase when these wavelengths help with flowering.

When growing indoors you’re trying your best to emulate the perfect outdoor conditions. Each phase of a plant’s growth (from vegetative to flowering stage) is being exposed to various wavelengths of light to maintain the process of photosynthesis and bud formation. Understanding the natural changes in sunlight and how plants react can help you improve your growing skills.

For better clarity, let’s look at the various colors along the light spectrum, their corresponding wavelengths and how they impact marijuana plants. They include:

Ultraviolet Spectrum

Ultraviolet or UV light has a wavelength that ranges from 10nm to 400nm; this type of light energy is known to be harmful to human skin when they are exposed to it. Our bodies react by developing a tan in an attempt to block light from further damaging skin cells. 

UV light in large amounts can also damage plants.

Two types of UV rays exist; UV-A (315-400nm) and UV-B (280-315nm). 

UV-A is considered harmful to marijuana plants. Regardless of its harmfulness (not just to cannabis but other plants as well), plants have evolved a natural defense mechanism against UV lights by secreting of enzymes, antioxidants, and chemicals to prevent more damage. However, at greater concentration, it’s still damaging to the plant.

UV-B on the other hand, when compared to UV-A, is far less harmful to cannabis plants. UV-B light seems to have a positive effect on cannabis plant growth. More research needs to be done to determine what the exact benefits are, but numerous growers swear that feeding plants UV-B light improves growth, flavor, and potency.

There are grow lights now which offer a full spectrum of visible light; that also includes infrared light and UV-B.

Violet Spectrum

Violet light is on the bottom end of the visual light spectrum. Its wavelength ranges from 380nm to 450nm. This range of light is considered to improve color, potency, and taste of flowers. Violet light isn’t a major growth factor compared to blue and red spectrum light.

“Blurples” 

Many LED grow lamps will give off light that looks purple. These types of lamps are fondly known as blurples. You would be wrong to think this was light from only the violet wavelength. Each LED bulb is designed to shine a specific wavelength of light. To maximize efficiency the entire lamp is made up of specific wavelengths LEDs that are connected to plant growth. Blue and red are the most predominant but sometimes other wavelengths like UVB and white light are added in smaller numbers. When you combine red and blue light our eyes see the color purple. Blurple LED lights give off very little of the violet wavelength.

Blue Spectrum

The blue spectrum of light is very important for cannabis plant growth. This wavelength lies between 450nm and 495nm. This color of light is best used at the sprout and vegetative stage of growth as it promotes rapid growth and development of the plant. 

Outdoors during spring blue light energy is abundant. This is a natural trigger for new growth. It also keeps marijuana plants stable by helping them grow a strong stem and aids in the process of photosynthesis. Plants that are blue light deficient often turn out pale or yellow and are often weak flopping over under their weight.

Blue light can easily and quickly be supplemented by using cool white fluorescent bulbs, but most LED and alternative grow lights will provide blue light as well.

This graph shows the available light spectrum on a Mars Hydro LED (Mars Reflector 192). As you can see it gives off a lot of blue and orange-red light. Fantastic for both veg and flower.

This graph shows the available light spectrum on the newer Mars Hydro LEDs that provide a more complete light spectrum (TSW 2000). As you can see it gives off much more green and yellow light.

Green Spectrum

This spectrum of light plays a role (albeit minor) in the growth of marijuana plants at various stages. Its wavelength ranges from 495nm to 570nm. 

Cannabis plants absorb very little green light energy, but there are reports that small amounts can affect growth.

For most growers, green light isn’t necessary for a successful grow. But, If you feel like growing cannabis with lights that have a more complete spectrum of color then a little bit of green energy is a big yes.

One thing that’s great about green light and cannabis is that it doesn’t trigger flowering. Cannabis is very sensitive to light and dark cycles. A small amount of light during the night period could trick your plants in thinking it’s time to flower. Cannabis doesn’t “see” green light making it the perfect color of light to use if you want to work on your plants during the night period.

Yellow Spectrum

Yellow light energy has a wavelength that ranges from 570nm to 590nm. It is of little importance during photosynthesis but yellow/red light is essential for the flowering stage of the plant’s growth as it promotes budding. 

Besides its usefulness in budding and flowering, it’s of very little use to the plant during the vegetative growth stage. Yellow light energy on its own is a minor contributor to photosynthesis.

Red Spectrum

The final color on the visible light spectrum is red. It has a wavelength that ranges from 620nm to 750nm. This light is necessary during the flowering stage of marijuana plants. Adding red light induces budding and flowering. Many cannabis growers will switch to a stronger red light source once their plant gets to the flowering stage. Red light mixed with blue gets the best response from cannabis plants.

What’s The Difference Between Cool and Warm Light?

You may hear people refer to light as either “cool” or “warm”. This describes the colors of the spectrum going from violet to red. Cool colors are on the lower end of the light spectrum (violet, blue, green), while warm colors are on the higher end (yellow, orange, red).  

What’s the best color light to use for cannabis seedlings

A seedling will respond best to blue light. Sprouts will stretch and grow tall if there’s not enough blue light available. Not much light power is needed at this stage since the plants are so small. Many growers will use 50 watt cool white CFL bulbs specifically for their seedlings and cuttings.

What’s the best color light to use for growing cannabis

During the vegetative stage of cannabis growth, plants react well to lots of blue light. It’s important to also provide some red light too. The combination of blue and red light is the recipe for growth.

What’s the best color light to use for flowering cannabis

Switching your plants over to light that is heavier in the orange/red part of the light spectrum will help induce flowering as well as improve it. Don’t drop the blue light altogether, it’s still required but in slightly smaller amounts than red and orange light.

The Bottom Line About Light and Cannabis

Nothing beats natural sunlight. Cannabis plants can grow huge outdoors in the right sunny conditions. Growlights only give off a fraction of the light energy the sun provides. Using limited spectrum lights are adequate for indoor growing. Blue light and red light will successfully grow a cannabis plant without any problems. Using grow lights that provide a fuller spectrum of visual light will have an affect on the plant and usually results in a bigger yield. Your decision on using different types of light will depend on your unique situation. If you’re thinking of upgrading your lights, try going for something that better emulates the sun like full spectrum lights made for growing plants.

NASA helps warn of dangerous algal blooms in lakes, reservoirs

http://tinyurl.com/y5dzfv52 Dangerous algal blooms could cause massive issues in coastal areas and lakes throughout america. When toxin-containing aquatic organisms multiply and kind a bloom, it could actually sicken individuals and pets, contaminate consuming water, and drive closures at boating and swimming websites. With restricted sources to watch these often-unpredictable blooms, water managers are turning to new applied sciences from NASA and its companions to detect and hold monitor of potential hazards. That is notably important in lakes and reservoirs that individuals use for each recreation and water provide. A brand new app for Android cellular gadgets, from the U.S. Environmental Safety Company (EPA) and now obtainable on Google play, will alert officers and members of the general public when a dangerous algal bloom may very well be forming, relying on particular modifications within the coloration of the water noticed by satellites. The app is a product of the multi-agency Cyanobacteria Evaluation Community, or CyAN. “The curiosity is to make use of distant sensing as an eye-in-the-sky, early warning system to get an image of dangerous cyanobacteria in U.S. inland lakes,” stated Jeremy Werdell, the NASA Goddard House Flight Middle lead for CyAN, which additionally contains the EPA, the U.S. Geological Survey (USGS) and the Nationwide Oceanic and Atmospheric Administration (NOAA). “Assets are restricted, and it isn’t attainable for everybody on the bottom to be monitoring all inland water our bodies all the time,” he stated. “Satellites are offering a instrument to assist inform how and when to expend sources to go and gather water samples.” NASA has been learning water high quality from area for many years, starting in 1978 with the Coastal Zone Colour Scanner instrument that used the colour of the ocean to review phytoplankton populations. With later devices, just like the Average Decision Imaging Spectroradiometer on NASA’s Terra and Aqua satellites, the decision was tremendous sufficient to tell apart bigger inland lakes and reservoirs, and scientists started to make use of the information to detect the signatures of cyanobacteria in recent water. Cyanobacteria happen naturally in lots of our bodies of water, from the Nice Lakes to small neighborhood ponds. In small numbers, these algae usually are not an issue. However below the best situations – heat water, daylight, plus vitamins that always wash off agricultural fields – cyanobacteria can multiply and kind doubtlessly poisonous blooms. Despite the fact that the person algae are microscopic, blooms may be seen from area. In huge numbers, cyanobacteria blooms can seem as massive inexperienced swaths and patches because of their important photosynthetic pigment. Their presence will also be detected utilizing fluorescence, which algal blooms emit in response to publicity to daylight. Utilizing the bloom’s distinctive traits, devices on the NASA/USGS Landsat satellites, the European House Company’s Copernicus Senteinel-2 and Copernicus Sentinel-Three satellites, in addition to a number of others, are capable of pinpoint the presence of algae. With laptop applications developed to crunch these satellite tv for pc observations from Sentinel-3, NASA supercomputers produce weekly experiences on the colour – and different water high quality info — of greater than 2,000 lakes throughout america as a part of the CyAN challenge, stated Bridget Seegers, a analysis scientist at Goddard in Greenbelt, Maryland. Customers of the brand new CyAN app will have the ability to mark a selected lake with a pin – which can seem as inexperienced if the lake seems bloom free, yellow if algae are current however beneath a sure threshold of concern, or crimson, indicating {that a} bloom is probably going current. It is designed not just for water high quality managers, Seegers stated, however for individuals placing a canoe on their automobile and debating the place to go, or an clothing store directing individuals to the most effective lake for kayaking. CyAN began in 2015, and has labored with state and native businesses to establish doubtlessly dangerous blooms, stated Blake Schaeffer, a analysis ecologist with the EPA and that company’s lead for this system. Water high quality managers with EPA Areas and Workplace of Water teamed up with CyAN to check and consider the app and satellite tv for pc knowledge, he stated, moreover, citizen scientist teams, tribal teams and the general public have proven curiosity within the knowledge as nicely. “We’re placing the ability of the satellite tv for pc info straight into the arms of the individuals,” Schaeffer stated. “They do not must mine for knowledge; they will choose to have the information pushed to them.” This system does have limitations, nevertheless. The satellites cannot see by way of clouds, and due to the decision of Sentinel-3A, lakes would have to be a bit greater than half a mile (900 meters) large to trace with the highest-quality knowledge. To see at even smaller lakes and reservoirs, Schaeffer and others are turning to Landsat. Due to points with clouds (and a much less frequent revisit), Landsat satellites, scientists get about one clear measurement of a given website each month. However with Landsat’s greater spatial decision, they will monitor water high quality info from greater than 60% of the U.S. lakes and reservoirs, or greater than 170,000 waterbodies. Landsat and Sentinel-Three are complementary; Landsat has better spatial decision whereas Sentinel-Three gathers knowledge over particular person websites extra regularly and detects wavelengths extra applicable for cyanobacteria. As well as, Landsat satellites have thermal sensors that can be utilized to watch floor temperature of lakes, which is beneficial, since hotter temperatures promote bloom development. Schaeffer is investigating methods to add that further issue into the monitoring program. Finally, the aim is to create a water high quality monitoring system that leverages knowledge from many sources – Sentinel-2, Landsat, and different satellites, in addition to info gathered on the water, stated Nima Pahlevan, a researcher at Goddard and member of the Landsat science crew. He and his crew are engaged on methods to greatest use Landsat and Sentinel knowledge to establish lakes, rivers, reservoirs and different water our bodies with extreme algae current. The Landsat mission has been working because the late 1970s, so researchers and water managers can monitor the historical past of a given lake to find out if every lake – or doubtlessly even a person pixel inside a picture of a lake – has modified, and if it signifies a bloom. “We’re hoping that with these photographs, produced in near-real time – inside as little as Three to four hours – we will construct a system to concern warnings which might be particular to every lake or reservoir,” Pahlevan stated. One problem the group is dealing with is that there aren’t many water measurements being taken throughout the completely different lakes to check with, and confirm, what the satellite tv for pc is reporting. With assist from the Landsat Venture Science Workplace, Pahlevan and collaborators have positioned three devices in Inexperienced Bay, Wisconsin, Lake Okeechobee, Florida, and Grizzly Bay, California, to take measurements of the water for comparability with Landsat and different satellite tv for pc measurements. With these knowledge from the sphere, and work this summer season which incorporates monitoring a handful of lakes utilizing Landsat and Sentinel-2, Pahlevan hopes to construct up this system and broaden it to an operational system with extra areas by summer season 2020. For individuals like Donalea Dinsmore, who works for the Wisconsin Division of Pure Assets (DNR), extra satellite tv for pc monitoring instruments could be a welcome addition to the suite of strategies the state makes use of to maintain a deal with on the place dangerous algal blooms happen. Every summer season, the division receives questions on whether or not the inexperienced muck floating on lakes is dangerous, or experiences of canine sickened after swimming in or consuming from a lake, she stated. Wisconsin’s DNR has employees who monitor lots of the hundreds of lakes within the state, however they cannot attain in every single place. “With 15,000 lakes, are you able to go to all of them? And relying on while you go to, you would possibly simply miss a bloom,” Dinsmore stated. “It may be a extremely difficult and costly monitoring program in case you go in blind.” ### By Kate Ramsayer NASA’s Goddard House Flight Middle, Greenbelt, Md.

Psoriasis Patient Information: All You Need to Know About PUVA Therapy

Also known as Photochemotherapy, PUVA is an acronym; P standing for a drug called Psoralen, U for ultra, V for violet, and A for the kind of ultraviolet radiation that is used in the therapy. UVA is a long wave radiation measuring between 320 and 400 nanometers in the UV spectrum. Psoralen is a chemical we source from plants that absorb UVA radiation for use in their food cycle. In the presence of radiation, Psoralen binds on to the cell DNA and slows down cell replication. This property of Psoralen is used in PUVA therapy to treat many skin diseases.   

In Psoriasis, due to a dysfunctional immune system, skin cells multiply rapidly and form crusty silvery scales appearing as reddish lesions over the skin surface. PUVA combines an oral drug with external radiation to control skin cell replication and slow down psoriasis. That’s how we get the term photochemotherapy.

What Role Does PUVA Play in Treating Psoriasis?

Psoriasis being an immunodeficiency disease causes abnormal growth of skin cells resulting in the skin becoming rough, reddish, and scaly in appearance. The condition causes much pain and discomfort. PUVA therapy has the potential of slowing down cell growth. This stops psoriasis in its tracks, allowing drugs to do the healing.

Are There Different Ways of Administering PUVA Therapy?

Psoralen is given orally and radiation therapy follows an hour later. Another method is to immerse the patient in a bath filled with diluted medicated water for around twenty minutes, followed by radiation therapy. Psoralen once imbibed by the body makes the skin sensitive enough to receive light in small doses over extended sessions.   

What Are the Pros and Cons of PUVA Therapy?

The major benefit from PUVA therapy is that radiation can be localized to specific areas of the skin. Also, Psoralen that makes the skin sensitive to light gets activated only on exposure of the skin to radiation. This controls any toxic side effect relating to the drug’s presence in the body.  Besides, Psoralen therapy affects only the area exposed to radiation, unlike other systemic drugs that spread all over the body. This is helpful in reducing the overall risk of triggering skin cancer.

Research confirms the effectiveness of Psoralen combined with radiation therapy in combating psoriasis.

The disadvantage of PUVA treatment is that it can’t be restricted to one session and requires supervised medical attention covering multiple sessions over a longer duration.

PUVA does not cure the underlying problem; it only prevents the condition from worsening. Therefore, one can’t stop the treatment midway after any noticeable improvement.   

How Is PUVA Given to Psoriasis Patients?

First Psoralen is taken orally as a pill, through injections or by way of an intravenous drip. At least an hour has to lapse before Psoralen makes the skin receptive to radiation. The Psoralen intake is measured according to the weight of the patient.

The degree of skin pigmentation plays a crucial role in deciding how much radiation the skin can absorb. Radiation therapy can be prolonged if the patient’s skin is darker. The patient is encased in a metallic box fitted with fluorescent lights measuring 48 inches that are positioned vertically. A light meter is programmed to deliver just the right dose of radiation before shutting down.  

What Is the Average Duration of the PUVA Treatment?

Around 15 sessions are required before psoriasis affected skin shows notable improvement. It takes at least two days for the skin-burn to subside and heal following radiation exposure. By assessing the skin’s pigmentation status, the physician determines if the radiation dosage can be safely hiked as each session progresses.

On completion of 30 sessions of Photochemotherapy, a decision is taken whether or not to continue further therapy. If the patient does not respond positively, the treatment is discontinued. If a visible improvement is noted, the physician may decide to continue sessions (in a limited way, with limited exposure) to maximize the benefit. The physician will always be mindful of the total radiation consumed in PUVA therapy to avoid triggering skin cancers.   

What Precautions Are Advised During the PUVA Therapy?

These are the best guidelines for Psoriasis patients receiving Photochemotherapy to safeguard their health:

Advice the doctor and clinical staff regarding medications being taken and eye problems, if any.

Cosmetics, ointments, and creams are to be avoided completely during PUVA treatment.

Meticulously adhere to session timings; never miss an appointment.

A uniform gap must be maintained from the point of taking the systemic drug to the moment of radiation exposure.

Ideally, allow a gap of two hours between a meal and the time the drug is administered.

Smoking and alcohol are strictly prohibited (or at least minimized substantially) before, during, and after PUVA treatment to maximize the benefits.

Avoid direct exposure to sunlight during the entire period of PUVA treatment.

The genital areas are shielded in men to avoid the risk of testicular cancer. Women of childbearing age are advised to follow contraception. Pregnant women are advised against Photochemotherapy to shield the gestating baby.

A broad-spectrum sunblock is applied to face and hands and other areas that are not targeted during PUVA.

Special goggles are provided to shield the eyes from radiation during PUVA.

During treatment days and non-treatment days, patients are advised to wear wrap-around anti-UV sunglasses till nightfall every day. Perspex tinted glasses can be used when indoors.

The body needs to be fully covered with hats, long-sleeved shirts, trousers, skirts, socks, shoes, and gloves when moving outdoors. Uncovered skin must be shielded with sunscreen.

What Are the Short-Term or Long-Term Side Effects of PUVA Therapy?

Burning and itching sensation over the affected skin, recurring headaches, and nauseous feelings are the short-term effects largely induced by Psoralen intake. The long-term effects are photo-aging of the skin, a spotted freckle-like appearance, increased sensitivity of the skin to daylight, and the greater risk of acquiring skin cancers like melanoma. Wearing protective glasses may be advised as a precaution against developing a cataract.

How Safe Is PUVA Therapy? Can You Die From PUVA?

PUVA is recommended mostly in cases where psoriasis is severe, and not when the skin condition is responding well to other treatments. PUVA is safe and effective in treating extreme skin conditions that do not respond to normal drugs and topical treatments. There is no reported instance of a patient dying due to PUVA radiation exposure.

Sufficient care is taken to limit the dose and the duration of UV rays used in PUVA. There is a reasonable gap between two radiation sessions to ensure the body gets sufficient time to recover and heal. Every session is followed by lab tests that monitor important health parameters. The photo therapist gets the go-ahead only if the patient is otherwise in good health and is capable of undergoing further therapy.    

How Is Vitamin D Correlated to PUVA Therapy?

Vitamin D plays a significant role in the healthy development of the body’s` immune system and supports human cells at various stages in their life cycles. Clinical research has revealed that Vitamin D levels are extremely low in psoriasis patients. This could be one of the reasons for such patients acquiring immunodeficiency disorders.

The vitamin is so important that it is manufactured within the body through limited exposure to sunlight. It follows that a higher intake of supplemental Vitamin D not only restores the immune system back to good health but also helps the body maximize the benefits of phototherapy.

Vitamin D is best absorbed through natural foods such as milk and dairy products, and through salmon and egg yolks. Vitamin D can also be taken as Vitamin D3 supplements in safe doses not exceeding 4000 IU per day during treatment.

The PUVA therapist normally checks the patient’s blood levels of Vitamin D and takes corrective action before calibrating radiation exposure.  

Conclusion

PUVA has proven to be effective and successful in treating moderate to severe case of psoriasis, especially severe plaque psoriasis. What makes the therapy unique is the combination of Psoralen (taken orally) and limited low-level exposure of the skin to UV radiation in a controlled environment (meaning a hospital). The treatment works on very low doses of UV radiation precisely because Psoralen makes the skin sensitive enough to receive the light.

The benefits of PUVA therapy far outweigh the risks posed by short-term side effects. Though a long-term side effect such as cancer cannot be ruled out entirely, physicians take adequate precautions to ensure excessive radiation exposure is avoided. Ultimately, it isn’t PUVA alone that gets the job done; you need to combine PUVA with regular medication, vitamin D supplementation, and major lifestyle changes including diet and exercise to make the most of this technological lifesaver.
