BREAKING: Hundreds of broiler chickens have died on a farm in Honduras, with high temperatures being blamed for their deaths.

[thoughtlessarse]

Scorching weather has baked Europe in more days of “extreme heat stress” than its scientists have ever seen. Heat-trapping pollutants that clog the atmosphere helped push temperatures in Europe last year to the highest or second-highest levels ever recorded, according to the EU’s Earth-watching service Copernicus and the World Meteorological Organization (WMO). Europeans are suffering with unprecedented heat during the day and are stressed by uncomfortable warmth at night. The death rate from hot weather has risen 30% in Europe in two decades, the joint State of the Climate report from the two organisations found. “The cost of climate action may seem high,” said WMO secretary-general Celeste Saulo, “but the cost of inaction is much higher”. The report found that temperatures across Europe were above average for 11 months of 2023, including the warmest September since records began. The hot and dry weather fuelled large fires that ravaged villages and spewed smoke that choked far-off cities. The blazes that firefighters battled were particularly fierce in drought-stricken southern countries such as Portugal, Spain and Italy. Greece was hit by the largest wildfire recorded in the EU, which burned 96,000 hectares of land, according to the report. Heavy rain also led to deadly floods. Europe was about 7% wetter in 2023 than the average over the last three decades, the report found, and one-third of its river network crossed the “high” flood threshold. One-sixth hit “severe” levels. “In 2023, Europe witnessed the largest wildfire ever recorded, one of the wettest years, severe marine heatwaves and widespread devastating flooding,” said Carlo Buontempo, director of the Copernicus climate change service.

New Device Which Can Withstand 1400C Temperatures Could Improve Solar Energy Production - Technology Org

New Device Which Can Withstand 1400C Temperatures Could Improve Solar Energy Production - Technology Org

An innovative probe which can operate in temperatures as high as molten lava has been created by researchers.

The team from the University of Bristol and CEA Commissariat à l’Energie Atomique in France have designed and successfully tested rotary blades for generating flow in molten silicon, crucial for industries such as steel or nuclear which rely on molten metal control and impurity detection.

Traditional lab analysis is slow, costly, and lacks real-time data. The scientists set out to develop a method for real-time impurity detection with a very low detection limit, the lowest true concentration, that will almost always be detected in molten silicon used for solar cells, tackling challenges like high temperatures environment and the presence of vapours and oxides.

Lead author Dr Younes Belrhiti senior research associate from Bristol’s School of Electrical, Electronic and Mechanical Engineering said: “Our study introduced an innovative high-temperature probe based on mechanical stirring, ensuring a clean, representative and stable surface for real-time chemical analysis of molten silicon.”

Spectroscopy techniques measure and analyze the interaction between electromagnetic radiation and matter to provide insights into the composition, structure, and properties of substances. LIBS (laser-induced breakdown spectroscopy) is a remote and fast spectroscopic technique that can be applied to any material (liquid, solid, and aerosol).

Recently, its application to metallurgical melts has known an increasing interest in controlling the melt. However, LIBS applications based on performing laser ablations on the top of a liquid present drawbacks due to the lack of renewal and stability of the analysed surface. The bath surface exposed to the furnace atmosphere may be chemically modified (oxidized or nitrated) leading to the presence of a slag so it is not representative of the chemical composition of the melt.

At high temperatures, vapours may interfere with a spectroscopy laser beam. In some cases, the spectrum emitted by the plasma can be masked by the hot metal emissions as it behaves like a black body. Considering these difficulties, several devices have been developed to apply LIBS on molten metals which have some limitations such as instability.

In this study, published today in the journal Heliyon, a mechanical stirring of the melt by innovative rotary blades is proposed to be combined with LIBS. Their rotation will generate a representative, renewed, and stable surface as the target of the LIBS laser for an in-situ analysis at high temperatures.

Dr Belrhiti added: “We designed and tested innovative rotary blades for generating flow in molten silicon. Then, we developed the associated probe coupled with the spectroscopic technique LIBS, ensuring its functionality in high-temperature conditions.

“The developed probe offers a faster and more cost-effective way to detect impurities in molten materials used for solar cells, thanks to innovative mechanical stirring and spectroscopy that ensures accurate real-time analysis, paving the way for more efficient solar energy production.”

The mechanical stirring-based probe enables efficient impurity detection in molten silicon, enhancing the quality control of photovoltaic cells. This technology can be adapted for various high-temperature applications beyond solar cells, such as in steel and nuclear industries.

Having validated their method on molten silicon, their next step is to explore its application in other high-temperature environments, broadening its potential industrial uses.

What do you mean by Venus floating cities?

I'm hoping to write a science fiction story about visiting Venus as part of the space race and I would love your input

Alright so the thing with Venus is that we're all very familiar with her horrible hell-death clouds and 900°F surface temperatures. We all understand the surface of Venus is not a fun place for humans to be.

But, nobody ever talks about the fact that ABOVE the hell-death clouds, Venus is a paradise. The most Earth-like environment we know of in the solar system, beyond Earth itself, is actually in the skies of Venus.

About 30 miles above the surface, the pressure is ~1 atmosphere, and the temperature ranges from 30 - 100°F, which is Happy Human™ standard pressure and temperature.

What's more, a breathable mix of oxygen and nitrogen provides over 60% the lifting power on Venus that helium does on Earth. In other words, a balloon full of human-breathable air would float to the habitable range of Venus's atmosphere. We could float a ship with the very air we breathe.

The other great thing about this is that it avoids one of the big problems with Mars colonization. On Mars, any habitat on the surface full of breathable air is vulnerable to leaks and explosive decompression, a la the Martian.

Floating on Venus, a balloon full of breathable air doesn't have a significant pressure difference between the inside and the outside. Which means, any leaks or tears would be very slow and manageable. You could fix that shit with duct tape!

Similarly, because the environment outside the balloon is so Earth-like, humans living there wouldn't need any big fancy pressurized suits for extravehicular work. We'd need air to breathe, maybe some heat protection, and protection against the acid rain. That's it. 

Venus also provides the tools to keep us fed! It's atmosphere is made primarily of carbon dioxide, even above the dense horrible clouds. What likes carbon dioxide? Plants from Earth!! Lets grow FOOD on FLOATING PLATFORMS in the SKIES of VENUS.

This whole idea actually came out of a NASA effort exploring potential Venus colonization. The program was called HAVOC - the High Altitude Venus Operational Concept.

It hasn't really gone anywhere, and as far as I know there are no real plans to revisit it. Unfortunately, from a practicality standpoint, Mars is a much more viable target for human colonization. Not only is it better poised for outer solar system exploration, being farther away from the sun, but living on Venus would come with too many complicated contingencies. In the event of a major failure on Venus, you'd need to fly to another base, or fuck off all the way to orbit. I understand why people aren't really in a hurry to live somewhere where landing on the surface means certain death.

But that doesn't mean I won't be forever and always enamored by the skies of Venus. Here's one of the artist concepts to come out of HAVOC.

I want to be there.

25 Years of Exploring the Universe with NASA's Chandra Xray Observatory

Illustration of the Chandra telescope in orbit around Earth. Credit: NASA/CXC & J. Vaughan

On July 23, 1999, the space shuttle Columbia launched into orbit carrying NASA’s Chandra X-ray Observatory. August 26 marked 25 years since Chandra released its first images.

These were the first of more than 25,000 observations Chandra has taken. This year, as NASA celebrates the 25th anniversary of this telescope and the incredible data it has provided, we’re taking a peek at some of its most memorable moments.

About the Spacecraft

The Chandra telescope system uses four specialized mirrors to observe X-ray emissions across the universe. X-rays that strike a “regular” mirror head on will be absorbed, so Chandra’s mirrors are shaped like barrels and precisely constructed. The rest of the spacecraft system provides the support structure and environment necessary for the telescope and the science instruments to work as an observatory. To provide motion to the observatory, Chandra has two different sets of thrusters. To control the temperatures of critical components, Chandra's thermal control system consists of a cooling radiator, insulators, heaters, and thermostats. Chandra's electrical power comes from its solar arrays.

Learn more about the spacecraft's components that were developed and tested at NASA’s Marshall Space Flight Center in Huntsville, Alabama. Fun fact: If the state of Colorado were as smooth as the surface of the Chandra X-ray Observatory mirrors, Pike's Peak would be less than an inch tall.

Launch

When space shuttle Columbia launched on July 23, 1999, Chandra was the heaviest and largest payload ever launched by the shuttle. Under the command of Col. Eileen Collins, Columbia lifted off the launch pad at NASA’s Kennedy Space Center in Florida. Chandra was deployed on the mission’s first day.

First Light Images

Just 34 days after launch, extraordinary first images from our Chandra X-ray Observatory were released. The image of supernova remnant Cassiopeia A traces the aftermath of a gigantic stellar explosion in such captivating detail that scientists can see evidence of what is likely the neutron star.

“We see the collision of the debris from the exploded star with the matter around it, we see shock waves rushing into interstellar space at millions of miles per hour,” said Harvey Tananbaum, founding Director of the Chandra X-ray Center at the Smithsonian Astrophysical Observatory.

A New Look at the Universe

NASA released 25 never-before-seen views to celebrate the telescopes 25th anniversary. This collection contains different types of objects in space and includes a new look at Cassiopeia A. Here the supernova remnant is seen with a quarter-century worth of Chandra observations (blue) plus recent views from NASA’s James Webb Space Telescope (grey and gold).

This image features deep data of the Cassiopeia A supernova, an expanding ball of matter and energy ejected from an exploding star in blues, greys and golds. The Cassiopeia A supernova remnant has been observed for over 2 million seconds since the start of Chandra’s mission in 1999 and has also recently been viewed by the James Webb Space Telescope.

Can You Hear Me Now?

In 2020, experts at the Chandra X-ray Center/Smithsonian Astrophysical Observatory (SAO) and SYSTEM Sounds began the first ongoing, sustained effort at NASA to “sonify” (turn into sound) astronomical data. Data from NASA observatories such as Chandra, the Hubble Space Telescope, and the James Webb Space Telescope, has been translated into frequencies that can be heard by the human ear.

SAO Research shows that sonifications help many types of learners – especially those who are low-vision or blind -- engage with and enjoy astronomical data more.

Celebrate With Us!

Dedicated teams of engineers, designers, test technicians, and analysts at Marshall Space Flight Center in Huntsville, Alabama, are celebrating with partners at the Chandra X-ray Center and elsewhere outside and across the agency for the 25th anniversary of the Chandra X-ray Observatory. Their hard work keeps the spacecraft flying, enabling Chandra’s ongoing studies of black holes, supernovae, dark matter, and more.

Chandra will continue its mission to deepen our understanding of the origin and evolution of the cosmos, helping all of us explore the Universe.

Long awaited, here is the soil map of Skyrim using the Canadian System of Soil classification. Brief description of my conclusions under the cut:

Chernozem: Whiterun Hold is likely home to the majority of Skyrim’s Chernozems. The majority of biological carbon sequestering in grassland environments are below ground, within the root systems. Organic material- humus, builds up, causing the upper layers of the soil to take on a dark colour. Additionally, Solonetzic soils could be present, peppered throughout the hold if the parent material to the soil is salty enough.

Cryosols are formed in Skyrim’s far North and high alpine regions. The mean annual soil temperature being 0 degrees C, with permafrost conditions. Freeze-thaw cycles lead to permafrost at the soils surface, but also cryoturbation: soil movement arising from frost action.

Additionally in mountainous regions, you would find Regosols. Soils which develop on unstable landforms and have had little time to develop, such as mountain slopes, or river floodplains.

Gleysols occur across the landscape of Skyrim, but primarily in Hjaalmarch. Gleysols are commonly found in depressions or low-lying areas where water saturates the soil continuously, leading to a molted characteristic to the soil.

Organic soils would primarily be found in the water saturated soils of Hjaalmarch. These are wetland soils found in forested areas and are commonly known as peat, muck, bogs or fens.

Borrowing from the USDA soil taxonomy, Inceptisols are light colored soils with moderate alteration, occurring under cool and cold climates. These soils would be found in the Eastmarch caldera.

Luvisols are associated with forested landscapes overlying loamy glacial till, or on clayey lacustrine deposits. Lake Honrich dominates a large portion of the Rift, according to UESP, seemingly draining from the lake. I believe this to be the site of a melted glacier, the lake being meltwater. Clay sediments are associated with lakes because of their deposition, coarser sediments bordering the lake near the shore, and finer particles at the deepest reaches. Additionally, at the end of the Karth river, where sandy deposits would be deposited at Solitude, before the stream looses power further down the river, leaving only clay to be deposited.

Podzols are associated with igneous parent materials, coniferous vegetation and high acidity. Primarily they are found in Falkreath Hold and Southern Eastmarch.

Brunisols are an intermediate stage between Regosols (undeveloped soils), and Podzol or Luvisols. I believe with the unstable, mountainous landscape of the Reach, soils would remain still rather undeveloped. Brunisols would also be interspersed among the Luvisols.

"Scientists have developed a way to dramatically reduce the cost of recycling certain electronic waste by using whey protein.

Their method allows for the easy recovery of gold from circuit boards at a cost of energy and materials amounting to 50 times less than the price of the gold they recover—these are the numbers that big business likes to see.

Indeed, the potential for scalability depends on this sort of cost savings, something traditional e-waste recycling methods just can’t achieve.

Professor Raffaele Mezzenga from ETH Zurich has found that whey protein, a byproduct of dairy manufacturing, can be used to make sponges that attract trace amounts of ionized gold.

Electronic waste contains a variety of valuable metals, including copper, cobalt, and gold. Despite gold’s public persona as being either money or jewelry, thousands of ounces of gold are used in electronics every year for its exceptional conductive properties.

Mezzenga’s colleague Mohammad Peydayesh first “denatured whey proteins under acidic conditions and high temperatures, so that they aggregated into protein nanofibrils in a gel,” writes the ETH Zurich press. “The scientists then dried the gel, creating a sponge out of these protein fibrils.”

The next step was extracting the gold: done by tossing 20 salvaged motherboards into an acid bath until the metals had dissolved into ionized compounds that the sponge began attracting.

Removing the sponge, a heat treatment caused the gold ions to aggregate into 22-carat gold flakes which could be easily removed.

“The fact I love the most is that we’re using a food industry byproduct to obtain gold from electronic waste,” Mezzenga says. In a very real sense, he observes, the method transforms two waste products into gold. “You can’t get much more sustainable than that!” ...

However the real dollar value comes from the bottom line—which was 50 times more than the cost of energy and source materials. Because of this, the scientists have every intention of bringing the technology to the market as quickly as possible while also desiring to see if the protein fibril sponge can be made of other food waste byproducts.

E-waste is a quickly growing burden in global landfills, and recycling it requires extremely energy-intensive machinery that many recycling facilities do not possess.

The environmental value of the minerals contained within most e-waste comes not only from preventing the hundreds of years it takes for them to break down in the soil, but also from the reduction in demand from new mining operations which can, though not always, significantly degrade the environments they are located in.

[Note: Absolutely massive understatement, mining is incredibly destructive to ecosystems. Mining is also incredibly toxic to human health and a major cause of conflict, displacement, and slavery globally.]

Other countries are trying to incentivize the recycling of e-waste, and are using gold to do so. In 2022, GNN reported that the British Royal Mint launched an electronically traded fund (ETF) with each share representing the value of gold recovered from e-waste as a way for investors to diversify into gold in a way that doesn’t support environmentally damaging mining.

The breakthrough is reminiscent of that old fairy tale of Rumpelstiltskin who can spin straw into gold. All that these modern-day, real-life alchemists are doing differently is using dairy and circuit boards rather than straw."

Uniima larvae come in large numbers but high mortality rate as these onigiri have to compete to become juveniles even in the egg case.

They start off with an egg wall. Their bodies are still clumbs of cells that slowly fill up the inside of the 'egg', consuming the included nutrients. Once they are ready, the baby grows it's own wall for the first time and 'hatches'.

After this the larvae molts as it grows with a new wall each time. During the whole larval period the shed skin sticks to the white. If adults don't clean them up, you will see multiple torn layers on top of the white, which can cause issues.

The white grows a straw. A somewhat brittle organ compared to that of ancestral larvae but functional enough to pierce under another whites wall (especially in the side seam). The larva actively feeds itself using this, though the food has to be liquid enough to get through the straw. They don't smell or see to search for food and will just wiggle the straw around until they can slurp. These triangles are mostly fat and liquids with other tissues in the center and thowards straw.

When they completely lose the straw (the entrance to it reforms), they start eating with their new mouth. At this point they also start making noise with their nostrils. Adult Uniima are sensitive to this much more than to the visual cuteness of the larva. This is often when adults start claming individuals to raise.

As the creature grows and gains complexity inside its own wall, it's new molts allow for use of more developed parts - anal cavity opens, ear cycles appear, eyes get bigger and closer to the wall surface, "mouth hands" with leathery pads emerge.. and lastly it's whole legs with fingers (often just silhouettes of feet show up rather then whole fingers or they are webbed).

After it's last stage and sufficient amounts of food, the white goes dormant to metamorphosise. This can take a week and less as most juvenile components are already in place.

The larval stages of Uniima can differ in length depending of environment - temperature, humidity, lack of food...

The average time from birth to metamorphosis is around 3 and half earth months.

The images here are not fully up to scale. Most larvae grow more between the stages but it's also not impossible for it to be to scale. I would just consider this larva a runt of the litter.
