If you were a sci-fi writer, how would you solve the Fermi paradox? That being the discrepancy between evidence for alien life, versus the likelihood of their existence? (basically. If alien so likely, why we not see?) The Dead Space series has an amazing cosmic horror solution, but i'm curious what you're brain could come up with!
There's a lot of possibilities, some more interesting than others.
The speed of light and the distance between inhabited stars makes it prohibitively slow to detect, make contact with, or reach any star with alien life. It doesn't matter if we're not alone, our corner of Space Reachable Within A Human Lifetime is so comparatively small that we may as well be. We're all blindly wandering through an infinite desert, calling into the void. Space exploration is a long game, and on that timescale, even whole civilizations blink out very quickly. If we manage to catch a signal and follow it, we might find nothing on the other end but ruins - or an asteroid field where a planet's orbit used to be.
The universe is too young for us to find anyone else out there. We're the first. How will we shape the galaxy to make life better for those who come after us?
The life that formed on Earth is terrifyingly invasive. The atmosphere and ocean is choked with monocellular life, and its surface is coated with a mass of multicellular organisms finding new ways to devour one another. Even extinction events don't keep down the biomass for long. If life on other planets looks anything like us, the problem isn't going to be detecting it. It'll have gotten everywhere. The problem is going to be not immediately getting colonized and eaten alive by it. And if life on other planets DOESN'T look like us, our whole planet is probably a class 1 biohazard and contamination risk. Multicellular earth organisms contain microcosmic ecosystems that proliferate explosively when they die. If anything inside them can find ANYTHING to eat, it's over.
Life evolves frequently, but always in oceans. It is extremely rare for any alien life to leave that ocean and adapt to life on land. Without this step, the jump to space exploration - even space contemplation - becomes infinitely more unlikely.
Monocellular life is seeded on planets from an outside source and allowed to self-cultivate and grow until the biomass reaches a certain volume. Then the farmers return to harvest it.
There is not a single other species on our entire planet that humans can actually reliably communicate with. It takes tremendous amounts of training to make an animal capable of recognizing even a handful of words, and very few of them can use them. Humans can't even communicate with other humans with 100% clarity, even if they're using the same language. When we find alien life, if we even recognize it as anything resembling life as we know it, we have absolutely no way of communicating.
Space colonialism has been disallowed by the space geneva conventions due to massive past tragedies, parasitic exploitation of worlds and senseless loss of life. Human expeditionary efforts are being watched warily through targeting sights.
We've known about radio communication for less than 200 years. We haven't yet figured out the medium through which all advanced civilizations communicate.
Alien life exists in abundance, but the vast majority of it is extremely tiny. We wouldn't spot an anthill on a satellite photo, and none of their ships are large enough to survive passage through our atmosphere.
Earth's oxygen atmosphere is an anomaly, and our first and most enduring extinction event. The explosive proloferation of cyanobacteria and their oxygen photosynthesis irreparably altered the planet's prebiotic atmosphere and wiped out everything that couldn't handle the sudden massive increase in a highly reactive and flammable gas. Earth is considered highly toxic and unstable, though recently detected increases in methane and CO2 might signal that nature is finally beginning to heal.

A Very Niche Level-Up + Looksmaxxing Idea List for 2025
This list is for the girls that get it. It’s niche and not for everyone, but I’m throwing up at the fact that every “how to level up in 2025” post talks about journaling sad pages 24/7, drinking 8 cups of water a day, and walking 10k steps. How original.
Tumblr media Tumblr media
Again, this is a very niche set of ideas. If you can’t relate then you can’t relate. But if you enjoy a good plastic surgery post and luxe lifestyle, maybe you will :)
1. Upgrade your car. We’re getting the Lexus’, the BMW’s, the Mercedes, the Jag’s, etc.
2. Upgrade your home. We’re living in high rises, we’re living in coastal areas, we’re living up in the mountains, we’re living where Amazon can drop our package off and we don’t have to worry about a porch pirate; we’re living in nice areas and in nice units/homes.
3. Breast augmentation.
4. Rhinoplasty.
5. Medical grade skincare.
6. Fresh, organic whole foods; focusing on lean protein, nuts and seeds, mushrooms, onions, leafy greens, pro/prebiotics, sea moss gel, etc.
7. Russian manicures and pedicures or a good acrylic set. Dip powder had its thing for a while but I’m not going to dip my nail in a powder everyone else dipped their nails. I bet they don’t even wash their hands and if they did, they prob didn’t even use soap.
8. Laser hair removal. Everywhere. If you want a design down there that’s cool, but you literally use the bathroom and it drips in the hair. “Oh but I use a wipe”. Okay, next time you need to wash your hair.. don’t use shampoo. Use a wipe. Invest in a bidet but still, hair shouldn’t be in your 🍑 or near the sensitive areas of your 🦋 the top is fine but if you have a period, pee, or “the other thing”, hair should be no where near those areas.
9. Lip filler. Everyone can benefit. Ask for a pout that sticks out a little bit. I don’t suggest a lip flip, I couldn’t do anything with a lip flip and it was driving me nuts.
10. Fake tan. Sunlight is fine but a spray tan just makes you look a million times better. Every skin tone and every race benefits from a spray tan. Trust.
11. Muscle definition. Muscle looks so much better than fat AND bones. You want muscle. Did you see how Bella Hadid had her foot on our necks at the VS fashion show this year? I was sickkkkkk.
12. Long hair. But if you have a face shape like Hailey Beiber, short hair looks better.
13. Makeup. Remember water-based products and oil-based products don’t mix, so make sure you choose your products wisely so your makeup doesn’t separate and you look a mess.
14. A better paying job. I left my hospital job and now I work in luxury real estate and international yacht sales.
15. Red light therapy for face and body. I have a body red light therapy dome that I got online for around $3,000 (USD) and it’s life. The one I have for the face is from Sephora and I spent like $400-$500 on that one. Whatever it says on the website.
16. Lashes. If you’re a pro at strip lashes, then yes. But I get my lashes done. Do not go crazy. Natural lashes are in so I ask for a classic whispy set focused for thickening my lash line and NOT for length.
17. Morpheus8 for skin tightening. I used it on my inner thighs and it literally saved my life
18. Lipo. If you’re a good candidate, get it. Sometimes belly pooch is hard to lose. I don’t have a pooch but I’m sure when I have kids I will.
19. Vampire facials. I can confidently say my best facials were vampire facials. My med spa charges around $950 for each facial
20. People can tell you’re wearing Shein. Their clothes are cute online but I’m going to hold your hand when I say this, they never look flattering in person when they’re being worn. People can see the loose thread and the see-through material. They also don’t fit anyone well and makes a lot of you look square. You get what you pay for in clothing. Learn about the basics of clothing and you’ll quickly only buy quality.
Yeah this list isn’t meant for everyone, but walking 10,000 steps isn’t going to take you to the next level. Neither is drinking water. They’re good habits, but they’re not going to level you up. And yeah I understand my list requires having money, but this is literally what my blog is about.
My 2025 Mindset Level Up book is here!

An international team of scientists has published a study highlighting the potential role of iron sulfides in the formation of life in early Earth's terrestrial hot springs. According to the researchers, the sulfides may have catalyzed the reduction of gaseous carbon dioxide into prebiotic organic molecules via nonenzymatic pathways. This work, appearing in Nature Communications, offers new insights into Earth's early carbon cycles and prebiotic chemical reactions, underscoring the significance of iron sulfides in supporting the terrestrial hot springs origin of life hypothesis.

COULD LIFE EXIST ON TITAN??
Blog#416
Saturday, July 6th, 2024.
Welcome back,
Titan's ocean has a volume 12 times that of all Earth's oceans, but it may be barren of life as we know it.
Titan's underground ocean, and similar oceans inside other icy moons in the outer solar system, may lack the organic chemistry necessary for life, according to new astrobiological research.
Tumblr media
Titan is Saturn's largest moon, and the second largest moon in the entire solar system. It's famous for being shrouded in a smog of petrochemicals and for possessing a veritable soup of organic molecules — molecules that contain carbon — on its surface. Yet, despite all this fascinating chemistry, Titan is cold. Very cold. It has surface temperatures no warmer than –179 degrees Celsius (–290 degrees Fahrenheit). And in these frigid conditions, chemical reactions for life progress very slowly.
Tumblr media
However, deep underground where it's warmer — the exact depth is not certain, but estimates suggest it's on the order of 100 kilometers (62 miles) — a liquid ocean with a volume 12 times that of Earth's oceans combined is thought to exist. Similar oceans inhabit the interiors of Titan's fellow Saturnian moon Enceladus, and Jupiter's moons Europa and Ganymede.
And where there is liquid water, there could be life. Right? Not so fast, says Catherine Neish of Western University in Ontario, Canada.
Tumblr media
A planetary scientist, Neish led an international team that challenged the assumption Titan's ocean, and indeed the oceans of other icy moons, could be habitable.
The researchers worked on the basis that, for Titan's ocean to be habitable, a large supply of organic molecules from the surface must be able to physically reach the ocean in order to facilitate prebiotic chemistry that can produce and feed life.
Tumblr media
The route for this organic material to reach the ocean is via comet impacts. Such impacts can melt surface ice, creating a pool of liquid water filled with organic molecules. Because liquid water is denser than ice, it sinks. But, Neish's modeling found that the rate of impacts is not high enough for sufficient organic material to reach Titan's ocean.
For example, Neish's team estimates only about 7,500 kilograms (16,534 pounds) of the simplest amino acid, glycine, reaches Titan's ocean every year. It may sound like a lot, but that's equivalent to the mass of one male African elephant spread across an ocean with a dozen times the volume of Earth's oceans. If you’ll excuse the pun, it's barely a drop in the ocean.
Tumblr media
"We assumed that the majority of melt deposits — 65% — would sink all the way to the ocean," Neish told Space.com. "Recent modeling work suggests that this is very likely an overestimate, but even in this most optimistic scenario, there is not enough organics moving into Titan's ocean to support life there."
There may be other possibilities. On Europa, where there are very few organic molecules on the surface, it is postulated that hydrothermal vents may exist on the seafloor where the ocean comes into contact with the moon's rocky core. These vents would spew all kinds of molecules and trigger complex chemical reactions that could support life.
Tumblr media
Further evidence for carbon in Europa's ocean has been discovered by the James Webb Space Telescope. The JWST identified carbon dioxide that has welled up from the ocean onto Europa's surface.
So, could the same happen on Titan, with organic material coming from the moon's interior, rather than its surface?
Neish doesn't rule it out, saying that colleagues such as Kelly Miller at the Southwest Research Institute in San Antonio, Texas, are investigating the possibility — but Neish does highlight one particular caveat.
Tumblr media
"One concern that has come up is whether the organics sourced from the interior would be useful for life," she said. "We think they may be primarily aromatic compounds, and it is difficult to form biomolecules — such as amino acids — from such compounds."
While we are still some ways away from being able to probe the oceans of these icy moons directly to say for certain whether they contain life or not, Neish's research does raise some promising opportunities for NASA's Dragonfly mission to Titan, on which Neish is a co-investigator.

Hi, I appreciate your blog as it helps me be more mindful in my daily habits
Do you have any suggestions for those trying to lower cortisol levels? Like activities, supplements, etc :) thanks in advance 🧚‍♀️
hello, it’s always so nice to hear that my posts help out a lot of you, thank you for sharing kind words! 🩷
supplements that can help are ashwagandha, omega-3 fatty acids, prebiotics and probiotics, arctic root, maca, ginkgo biloba, L-theanine, magnesium glycinate. of course when it comes to supplements, keep in mind any medications you’re on, or allergens you can possibly have. speak to your doctor, or at least do proper research about certain supplements before taking them. i don’t know your medical history or lifestyle to force personal suggestions! and i say that for any advice given here, take everything into consideration and do your part in educating for your personal needs/wants!
other things to follow —
eating nutrient dense home cooked meals. avoid over consuming processed foods, artificial sweeteners, etc.
limiting your daily blue light exposure as much as possible.
do not drink coffee on a empty stomach.
stay focused on what you can control, rather than what you can’t. learn to balance your emotions.
limit your media consumption. it’s definitely important to be aware of what’s going on worldwide, but if you’re someone who gets easily affected by it, keep your exposure to a minimum. same goes for who you follow on social media. if you find that certain things trigger you or you find yourself feeling disappointed in yourself due to comparison, follow those you motivate you.
adrenal cocktails.
levelling your vagus nerve.
expose yourself to safe daily sunlight + spend more time outdoors.
self care routines that calm you.
opt for low impact movement daily like walking, pilates, yoga, etc.
keep your home/space clean and organized.
get proper sleep.
improve your circadian rhythm.
set firm boundaries.

Got a lot of responses to a previous post about poverty and environmentalism and I have come to the conclusion that people genuinely don't understand just how little autonomy a lot of poor people have. Ideally, we'd all vote with our dollars for a better world, but many of us don't have much to vote with.
By virtue of being poor, low-income people already buy few clothes and use what they have until it wears out. They mostly thrift and wear hand-me-downs, and take what they can get. If they need something specific (like a certain color of clothes for a uniform or a safety shoe for work), they buy it from Wal-Mart or whatever they can access locally. Perhaps they might like to "buy something sustainable" that would last longer, but longer-lasting clothes are no longer available where they live. Their options for new clothes are "decent mall brand" and "shitty mall brand," and it's hard to justify the price increase if they both wear out just as fast. They could buy online and have more options, but given how hard it is to find good clothes while plus size, they might be hesitant to take the risk of online shopping - especially if returns means going to the post office across town. Perhaps they should be sewing their own clothes, but that's just another chore heaped at their feet, something they hope to get around to when they have the spare the energy and money to learn.
A poor person cannot will a working public transportation system into being on their own, nor can they easily justify getting a more fuel-efficient car (if they can afford a car at all). Hopefully, they have reliable public transportation with benches to sit on and covered stops for when it rains. Hopefully the busses run late enough for second and third-shift workers and don't stop running when the office workers get home. Another thing people don't think about it the fact that perhaps a poor person COULD take public transportation, but can't physically handle an hour plus on the bus after work for a journey that takes no more than twenty minutes by car.
Poor people are often harangued about "eating better," whatever that means, but no one is willing to admit that poverty also brings time poverty, energy poverty, and lack of storage space. Sure, we should all be eating home-cooked, locally-sourced, organic vegan paleo keto probiotic prebiotic low-carb high-carb blue zone food, but after a long shift, not everyone has the mental and physical energy to prepare a meal to that standard. And the answer is always that we should meal prep it all. Not everyone has refrigerator space like that, given that many us live doubled up, couch surf, or live out of cars. Many of us just eat what we can prepare, given lack of proper kitchens, disability, and time poverty.
None of this is intended to make people feel bad, it simply represents my own lived experience and how frustrated I feel as someone with an interest in the environment and a long history of making due without much money. So much dialog about the environment focuses on trimming excess, but many people don't have that much excess to trim.
Instead of shaming people for not doing this or that, why not make it possible for them to do so? Consider organizing a clothing swap, either in your community or for friends. Advocate for public transport in your community, and offer to carpool with friends that need it. See if there's a community garden or a food sovereignty project in your area, or just start growing if you have a backyard and some friends to help out. Advocate for good recycling programs that don't involve driving miles in a car to a recycling center. If you make a useful craft (like lotion bars or soap, for example!), give some to your friends so they don't have to buy the plastic-wrapped version at the store. Above all, be conscious of the barriers that stand between people and sustainable living. I think we could all do better to focus on breaking barriers down, not people down.

Carl Sagan’s scientific legacy extends far beyond ‘Cosmos’
Tumblr media
by Jean-Luc Margot, Professor of Earth, Planetary, and Space Sciences at the University of California, Los Angeles
On Nov. 9, 2024, the world will mark Carl Sagan’s 90th birthday – but sadly without Sagan, who died in 1996 at the age of 62.
Most people remember him as the co-creator and host of the 1980 “Cosmos” television series, watched worldwide by hundreds of millions of people. Others read “Contact,” his best-selling science fiction novel, or “The Dragons of Eden,” his Pulitzer Prize-winning nonfiction book. Millions more saw him popularize astronomy on “The Tonight Show.”
What most people don’t know about Sagan, and what has been somewhat obscured by his fame, is the far-reaching impact of his science, which resonates to this day. Sagan was an unequaled science communicator, astute advocate and prolific writer. But he was also an outstanding scientist.
Sagan propelled science forward in at least three important ways. He produced notable results and insights described in over 600 scientific papers. He enabled new scientific disciplines to flourish. And he inspired multiple generations of scientists. As a planetary astronomer, I believe such a combination of talents and accomplishments is rare and may occur only once in my lifetime.
Scientific accomplishments
Very little was known in the 1960s about Venus. Sagan investigated how the greenhouse effect in its carbon dioxide atmosphere might explain the unbearably high temperature on Venus – approximately 870 degrees Fahrenheit (465 degrees Celsius). His research remains a cautionary tale about the dangers of fossil fuel emissions here on Earth.
Sagan proposed a compelling explanation for seasonal changes in the brightness of Mars, which had been incorrectly attributed to vegetation or volcanic activity. Wind-blown dust was responsible for the mysterious variations, he explained.
Tumblr media
Sagan and his students studied how changes to the reflectivity of Earth’s surface and atmosphere affect our climate. They considered how the detonation of nuclear bombs could inject so much soot into the atmosphere that it would lead to a yearslong period of substantial cooling, a phenomenon known as nuclear winter.
With unusual breadth in astronomy, physics, chemistry and biology, Sagan pushed forward the nascent discipline of astrobiology – the study of life in the universe. Together with the research scientist Bishun Khare at Cornell University, Sagan conducted pioneering laboratory experiments and showed that certain ingredients of prebiotic chemistry, called tholins, and certain building blocks of life, known as amino acids, form naturally in laboratory environments that mimic planetary settings.
Tumblr media
He also modeled the delivery of prebiotic molecules to the early Earth by asteroids and comets, and he was deeply engaged in the biological experiments onboard the Mars Viking landers. Sagan also speculated about the possibility of balloon-shaped organisms floating in the atmospheres of Venus and Jupiter.
His passion for finding life elsewhere extended far beyond the solar system. He was a champion of the search for extraterrestrial intelligence, also known as SETI. He helped fund and participated in a systematic search for extraterrestrial radio beacons by scanning 70% of the sky with the physicist and electrical engineer Paul Horowitz.
He proposed and co-designed the plaques and the “Golden Records” now affixed to humanity’s most distant ambassadors, the Pioneer and Voyager spacecrafts. It is unlikely that extraterrestrials will ever find these artifacts, but Sagan wanted people to contemplate the possibility of communication with other civilizations.

Advocacy
Sagan’s scientific output repeatedly led him to become an eloquent advocate on issues of societal and scientific significance. He testified before Congress about the dangers of climate change. He was an antinuclear activist and spoke out against the Strategic Defense Initiative, also known as “Star Wars.” He urged collaborations and a joint space mission with the Soviet Union, in an attempt to improve U.S.-Soviet relations. He spoke directly with members of Congress about the search for extraterrestrial intelligence and organized a petition signed by dozens of prominent scientists urging support for the search.

But perhaps his most important gift to society was his promotion of truth-seeking and critical thinking. He encouraged people to muster the humility and discipline to confront their most cherished beliefs – and to rely on evidence to obtain a more accurate view of the world. His most cited book, “The Demon-Haunted World: Science as a Candle in the Dark,” is a precious resource for anyone trying to navigate this age of disinformation.
Impact
A scientist’s impact can sometimes be gauged by the number of times their scholarly work is cited by other scientists. According to Sagan’s Google Scholar page, his work continues to accumulate more than 1,000 citations per year.
Indeed, his current citation rate exceeds that of many members of the National Academy of Sciences, who are “elected by their peers for outstanding contributions to research,” according to the academy’s website, and is “one of the highest honors a scientist can receive.”
Sagan was nominated for election into the academy during the 1991-1992 cycle, but his nomination was challenged at the annual meeting; more than one-third of the members voted to keep him out, which doomed his admission. An observer at that meeting wrote to Sagan, “It is the worst of human frailties that keeps you out: jealousy.” This belief was affirmed by others in attendance. In my opinion, the academy’s failure to admit Sagan remains an enduring stain on the organization.
No amount of jealousy can diminish Sagan’s profound and wide-ranging legacy. In addition to his scientific accomplishments, Sagan has inspired generations of scientists and brought an appreciation of science to countless nonscientists. He has demonstrated what is possible in the realms of science, communication and advocacy. Those accomplishments required truth-seeking, hard work and self-improvement. On the 90th anniversary of Sagan’s birth, a renewed commitment to these values would honor his memory.

What does a 90's Superboy comic book has to say about the biochemical evolution of early life on Earth
Tumblr media
I love bad science in comic books and I'm glad there's so much to choose from, from the 1940s to today. Even though I'm a biology teacher and usually dislike when media gets Evolution so wrong, spreading disinformation about an already complex scientific theory, I still have a soft spot for these comics that try to implement evolutionary concepts and fail. And this Superboy issue does just that, but in such an entertaining way, I had a few good laughs and saw it as a learning opportunity.
In this issue there's a Superboy "animated series" pilot being produced featuring the real Kon-el and his entourage, this is a brain child of Rex Leech, Superboy's manager at this time in the comics. We see the "animation" as the characters watch it in the comic. In the pilot episode Rex reveals that his daughter, Roxy, was turned into "primordial slime" (panel above) by a villain. This is a reference to the "primordial soup" concept from the heterotrophic theory proposed by the scientists Oparin and Haldane. They stated that a prebiotic liquid with lots of elemental molecules evolved into organic molecules due to the intense conditions the primitive Earth faced (thunderstorms, volcanic activities, asteroid bombardment etc). Then, said organic molecules later grouped in cell-like structures (coacervates) capable of replication, thus creating a primitive form of life.
Roxy IS that prebiotic soup, a slime contained in a glass, that tragically gets shot during the pilot, leaking into an underground pool of undetermined origin water (in which Superboy says he occasionally bathes in).
Tumblr media
Behold then, that by the end of the pilot (panel right above), Rex, Kon and Dubbilex discover the pool of mysterious water changed, now that Roxy was mixed into it... EVOLVING into algae (according to Dubbilex) and a fungus (according to an emotional Rex - happy to see his daughter once again alive in the form of this green goop). To be clear, algae and fungi are as different as insects are from trees, they're not only into separate biological kingdoms, but while algae has a machinery to make photosynthesis and produce their own food, fungi cells need to extract their energy from their surroundings (soil, trees, animals, you and me) and they have a cell wall made of the same material as insects exoskeletons! So, pretty different...
But the most insane thing about this development in the story is the implied idea that Roxy is evolving, going from organic slime to unicelular algae to fungi and... what's next? According to Rex (in the panel below - when the animation episode ends and real life Roxy is upset about being turned into a fungus) - A slug - oh yes, the next big step in evolution.
Tumblr media
This was so funny to me because it's a different way to portray that old and very wrong idea that the evolutionary process is like a set of stairs in which life is slowly going up, higher and higher, getting "better and better", step by step. While truly, a more realistic view of evolution would look like a twisted tree of ramifications, some going nowhere, some staying apparently the same, and some getting more and more twisted by the minutes (yes, those would be bacteria).
Tumblr media Tumblr media
Evolution is not a progression from less complex to more complex, evolution is simply changing, adapting, transforming through time. Birds would consider humans lesser beings for our lack of wings the same way most of us consider flatworms lesser for their lack of, well, lots of stuff, arms, backbone, blood, a respiratory system. And yet, we're all equally well adapted to our respective habitats, we are on the same level because we are alive and thriving, there's no hierarchy in evolution.
To think that Roxy would go from primordial slime to algae to fungi until potentially reach the complexity level of a human being is, as Dubillex put it in that panel above: bad science. However I had so much fun reading this story. I don't know if it's right as a biology teacher to have such an enthusiasm for bad science in comics, but I refuse to deny Art! I'd love to bring this issue to my students so we could read it in group and interpret together the message implied in Roxy's "evolution", and what is wrong about it. It would be a nice way to make the students read the comics I enjoy and learn something about real science.
My favorite thing about this issue is that the butt of the joke does not seem to be the theory of Evolution, but the distorted view someone can have of it. I didn't highlight it here, but in the end, there was a lot comically wrong with the pilot besides the Roxy "evolution" plot. So when Dubillex acknowledges to Rex that his pilot episode is not educational, but presents poor science, it's clear to me we're laughing at Rex's perception of scientific ideas and not at the ideas themselves. Which is refreshing. Yes, this is my favorite issue of this Superboy run so far and yes I'm biased.

Shiitake mushrooms (Lentinula edodes) are prized not only for their rich, savory flavor but also for their impressive health benefits. Here are some of the key benefits of consuming shiitake mushrooms
1. Boosts Immune System
• Shiitake mushrooms contain polysaccharides like lentinan, which enhance immune function by increasing the activity of immune cells, such as T cells and macrophages.
2. Supports Heart Health
• Lowers cholesterol: Compounds like eritadenine and beta-glucans in shiitake mushrooms help reduce “bad” LDL cholesterol levels.
• Improves circulation: Shiitake’s antioxidants, such as selenium, support cardiovascular health by reducing inflammation and oxidative stress.
3. Rich in Nutrients
• Shiitake mushrooms are an excellent source of essential nutrients like:
• B vitamins (B2, B3, B5): Support energy production and brain health.
• Vitamin D (when exposed to sunlight): Improves bone health and immune function.
• Minerals like copper, selenium, and manganese: Aid in antioxidant defense and energy production.
4. Antioxidant Properties
• Shiitake mushrooms are rich in antioxidants like polyphenols and ergothioneine, which help neutralize free radicals, reduce oxidative stress, and lower the risk of chronic diseases.
5. Supports Skin and Hair Health
• The high selenium and zinc content in shiitake mushrooms helps maintain healthy skin and hair by reducing inflammation and promoting repair.
6. Aids in Weight Management
• Shiitake mushrooms are low in calories and high in dietary fiber, which promotes a feeling of fullness, aids digestion, and supports healthy weight loss.
7. Anti-Cancer Properties
• Lentinan, a polysaccharide in shiitake mushrooms, has been shown to exhibit anti-tumor effects by boosting the immune system and slowing cancer cell growth.
8. Improves Gut Health
• The prebiotic fibers in shiitake mushrooms feed beneficial gut bacteria, which improves digestion and supports a healthy microbiome.
9. Fights Inflammation
• Shiitake mushrooms contain compounds like ergothioneine and polysaccharides that help reduce inflammation and prevent chronic inflammatory conditions.
10. May Help Prevent Infections
• Shiitake mushrooms exhibit antibacterial, antifungal, and antiviral properties, which may help protect against common infections.
How to Incorporate Shiitake Mushrooms
• Add fresh or dried shiitake mushrooms to soups, stir-fries, and sauces.
• Use shiitake mushroom powder as a seasoning or in teas for a concentrated dose of nutrients.
• Sauté them with garlic and herbs for a flavorful side dish.
While shiitake mushrooms offer many benefits, consuming them in moderation is advised to avoid potential side effects like skin irritation (shiitake dermatitis) or digestive discomfort in sensitive individuals.

Rocks collected on Mars hold key to water and perhaps life on the planet. Bring them back to Earth.
Only Earth-based analysis of sediments gathered by rover can retrieve clues to Mars' water history
Over the course of nearly five months in 2022, NASA's Perseverance rover collected rock samples from Mars that could rewrite the history of water on the Red Planet and even contain evidence for past life on Mars.
But the information they contain can't be extracted without more detailed analysis on Earth, which requires a new mission to the planet to retrieve the samples and bring them back. Scientists hope to have the samples on Earth by 2033, though NASA's sample return mission may be delayed.
"These samples are the reason why our mission was flown," said paper co-author David Shuster, professor of earth and planetary science at the University of California, Berkeley, and a member of NASA’s science team for sample collection. "This is exactly what everyone was hoping to accomplish. And we've accomplished it. These are what we went looking for."
The critical importance of these rocks, sampled from river deposits in a dried-up lake that once filled a crater called Jezero, is detailed in a study to be published Aug. 14 in AGU Advances, a journal of the American Geophysical Union.
"These are the first and only sedimentary rocks that have been studied and collected from a planet other than Earth," said paper co-author David Shuster, professor of earth and planetary science at the University of California, Berkeley, and a member of NASA’s science team for sample collection. "Sedimentary rocks are important because they were transported by water, deposited into a standing body of water and subsequently modified by chemistry that involved liquid water on the surface of Mars at some point in the past. The whole reason that we came to Jezero was to study this sort of rock type. These are absolutely fantastic samples for the overarching objectives of the mission."
Shuster is co-author of the paper with first author Tanja Bosak, a geobiologist at the Massachusetts Institute of Technology (MIT) in Cambridge.
"These rock cores are likely the oldest materials sampled from any known environment that may have supported life," Bosak said. "When we bring them back to Earth, they can tell us so much about when, why and for how long Mars contained liquid water, and whether some organic, prebiotic and potentially even biological evolution may have taken place on that planet."
Significantly, some of the samples contain very fine-grained sediments that are the most likely type of rock to retain evidence of past microbial life on Mars — if there ever was or is life on the planet.
"Liquid water is a key element in all of this because it is the key ingredient for biological activity, as far as we understand it," said Shuster, a geochemist. "Fine-grained sedimentary rocks on Earth are those that are most likely to preserve signatures of past biological activity, including organic molecules. That's why these samples are so important."
NASA announced on July 25 that Perseverance had collected new rock samples from an outcrop named Cheyava Falls that also might contain signs of past life on Mars. The rover's scientific instruments detected evidence of organic molecules, while "leopard spot" inclusions in the rocks are similar to features that on Earth are often associated with fossilized microbial life.
In a statement, Ken Farley, Perseverance project scientist at Caltech, said, “Scientifically, Perseverance has nothing more to give. To fully understand what really happened in that Martian river valley at Jezero crater billions of years ago, we’d want to bring the Cheyava Falls sample back to Earth, so it can be studied with the powerful instruments available in laboratories.”
Sediments hold the answers
Shuster noted that Jezero and the fan of sediments left behind by the river that once flowed into it likely formed 3.5 billion years ago. That abundant water is now gone, either trapped underground or lost to space. But Mars was wet at a time when life on Earth — in the form of microbes — was already everywhere.
"Life was doing its thing on Earth at that point in time, 3.5 billion years ago," he said. "The basic question is: Was life also doing its thing on Mars at that point in time?"
"Anywhere on Earth over the last 3.5 billion years, if you give me the scenario of a river flowing into a crater transporting materials to a standing body of water, biology would have taken hold there and left its mark, in one way or another," Shuster said. "And in the fine-grained sediment, specifically, we would have a very good chance of recording that biology in the laboratory observations that we can make on that material on Earth."
Shuster and Bosak acknowledge that the organic analysis equipment aboard the rover did not detect organic molecules in the four samples from the sedimentary fan. Organic molecules are used and produced by the type of life we're familiar with on Earth, though their presence is not unequivocal evidence of life.
"We did not clearly observe organic compounds in these key samples," Shuster said. "But just because that instrument did not detect organic compounds does not mean that they are not in these samples. It just means they weren't at a concentration detectable by the rover instrumentation in those particular rocks."
To date, Perseverance has collected a total of 25 samples, including duplicates and atmospheric samples, plus three "witness tubes" that capture possible contaminants around the rover. Eight duplicate rock samples plus an atmospheric sample and witness tube were deposited in the so-called Three Forks cache on the surface of Jezero as a backup in case the rover suffers problems and the onboard samples can't be retrieved. The other 15 samples — including the Cheyava Falls sample collected July 21 — remain aboard the rover awaiting recovery.
Shuster was part of a team that analyzed the first eight rock samples collected, two from each site on the crater floor, all of which were igneous rocks likely created when a meteor impact smashed into the surface and excavated the crater. Those results were reported in a 2023 paper, based on analyses by the instruments aboard Perseverance.
The new paper is an analysis of seven more samples, three of them duplicates now cached on Mars' surface, collected between July 7 and November 29 of 2022 from the front of the western sediment fan in Jezero. Bosak, Shuster and their colleagues found the rocks to be composed mostly of sandstone and mudstone, all created by fluvial processes.
"Perseverance encountered aqueously deposited sedimentary rocks at the front, top and margin of the western Jezero fan and collected a sample suite composed of eight carbonate-bearing sandstones, a sulfate-rich mudstone, a sulfate-rich sandstone, a sand-pebble conglomerate," Bosak said. "The rocks collected at the fan front are the oldest, whereas the rocks collected at the fan top are likely the youngest rocks produced during aqueous activity and sediment deposition in the western fan."
While Bosak is most interested in possible biosignatures in the fine-grained sediments, the coarse-grained sediments also contain key information about water on Mars, Shuster said. Though less likely to preserve organic matter or potential biological materials, they contain carbonate materials and detritus washed from upstream by the now-vanished river. They thus could help determine when water actually flowed on Mars, the main emphasis of Shuster's own research.
"With lab analysis of those detrital minerals, we could make quantitative statements about when the sediments were deposited and the chemistry of that water. What was the pH (acidity) of that water when those secondary phases precipitated? At what point in time was that chemical alteration taking place?" he said. "We have this combination of samples now in the sample suite that are going to enable us to understand the environmental conditions when the liquid water was flowing into the crater. When was that liquid water flowing into the crater? Was it intermittent?"
Answers to these questions rely upon analyses of the returned materials in terrestrial laboratories to uncover the organic, isotopic, chemical, morphological, geochronological and paleomagnetic information they record, the researchers emphasized.
"One of the most important planetary science objectives is to bring these samples back," Shuster said.

Apple cider vinegar, or ACV, has been touted for its numerous health benefits for centuries. Here are some of the most well-researched benefits:
Digestive aid: ACV contains acetic acid, which helps break down proteins and carbohydrates, reducing symptoms of indigestion and bloating. Why: Acetic acid's pH level helps to balance the body's natural digestive processes.
Weight loss: ACV contains pectin, a soluble fiber that helps reduce appetite and increase feelings of fullness. Why: Pectin slows down the absorption of glucose and insulin, leading to weight loss.
Lower blood sugar levels: ACV contains acetic acid, which has been shown to improve insulin sensitivity and reduce glucose production in the liver. Why: Acetic acid's ability to improve insulin sensitivity helps regulate blood sugar levels.
Heart health: ACV contains polyphenols, such as quercetin and epicatechin, which have antioxidant properties that help reduce inflammation and oxidative stress. Why: Polyphenols' antioxidant properties protect against cardiovascular disease by reducing inflammation and oxidative stress.
Antimicrobial properties: ACV contains acetic acid, which has antibacterial and antifungal properties that help combat infections. Why: Acetic acid's antimicrobial properties make it effective against a wide range of microorganisms.
Anti-inflammatory: ACV contains polyphenols, such as quercetin and epicatechin, which have anti-inflammatory properties that help alleviate symptoms of conditions like arthritis and gout. Why: Polyphenols' anti-inflammatory properties reduce inflammation and alleviate symptoms.
Improved dental health: ACV contains acetic acid, which helps reduce tooth decay and gum disease by killing bacteria and acid-producing microbes in the mouth. Why: Acetic acid's antibacterial properties eliminate harmful bacteria that contribute to tooth decay.
Lower cholesterol levels: ACV contains acetic acid, which has been shown to inhibit the production of cholesterol in the liver. Why: Acetic acid's ability to inhibit cholesterol production reduces LDL cholesterol levels.
Improved gut health: ACV contains prebiotic fibers like pectin, which help promote the growth of beneficial gut bacteria. Why: Prebiotic fibers feed beneficial bacteria, supporting a healthy gut microbiome.
Antioxidant-rich: ACV contains antioxidants like quercetin and epicatechin, which help protect against oxidative stress and cell damage caused by free radicals. Why: Antioxidants neutralize free radicals, reducing oxidative stress and cell damage.
be cautious about quality/quantity vinegar consumption.
Use organic, unfiltered, unprocessed apple cider vinegar, which is cloudy, meaning it contains the “mother.”
Two teaspoons to two tablespoons is the general dosage recommendation. If you want to drink it, dilute it with water or your favorite juice or tea.
Oral: For diabetes, dilute 2 tablespoons apple cider vinegar in 8 ounces of water daily. For weight loss, drink diluted dose with high carbohydrate meals.

Got a haircut today and spent some time with my mates at the barbershop. Everyone seems interested in my fucking sex life and who I'm fucking right now. Why are these casual topics of conversation? People need to mind their own business. Came home and smashed the iron. Over the last week I've added weight to all my lifts, especially to my curls, shoulder presses, bench, deadlifts, and rows. Looking for a new vegan protein powder because the pea protein powder I've been using (it's the only unflavoured vegan protein in my local area) isn't the highest quality. Will buy some organic hemp protein powder or there's this organic & sprouted brown rice protein that looks quality, too. I've heard good things about soy protein isolate as well. The thing with any high protein diet is that you've gotta make sure you're on top of your fibre (which is prebiotic) and your probiotics too. Your gut is your second brain. Gotta take care of it and treat it with respect. Vegans tend to have to worry less about their gut health but you can never be too careful when it comes to your health, you can never be too healthy, and you can never be too fit. Keep clean, lean, and sober. "I can't keep up, I'm out of step with the world" - Ian MacKaye

NASA's delayed Dragonfly drone mission to Saturn's largest moon Titan is on track to launch in July 2028, the space agency confirmed late Tuesday (April 16). The highly anticipated decision greenlights the mission team to proceed to final mission design and testing in preparation for the revised launch date. The car-sized Dragonfly, which is being built by the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, will reach Titan in 2034. For the next 2.5 years, the nuclear-powered drone is expected to perform one hop every Titan day — 16 days to us Earthlings — hunting for prebiotic chemical processes at various pre-selected locations on the frigid moon, which is known to contain organic materials.
