Reducing Biological Age By 67% : The Origins Of E5

Posted by in categories: biotech/medical, genetics, life extension

So if I heard this right, after 8 minutes or so, the effects are temporary and he indicates people would have to take this every couple of years.

Here Akshay talks about his interest in aging, how he met with Dr Katcher and formed Yuvan Research and their experiments with E5 and the results that they saw.

Cooling Functions of Forests: Investigating Microclimate Mechanisms

Posted by in categories: climatology, sustainability

How do forests cool themselves during the summer? This is what a recent study published in Agricultural and Forest Meteorology hopes to find out as a team of international researchers investigated the forests cool themselves through water evaporation and shading. However, climate change could have drastic consequences towards this type of natural air conditioning, specifically from droughts that dry up the soil, disabling a forest’s ability to stay cool during hot months.

For the study, the researchers collected daily measurements over four straight summer seasons of soil moisture and air temperature across 54 sites in broadleaf forests throughout Central Europe. They discovered that shaded forests were typically 2 degrees Celsius (36 degrees Fahrenheit) cooler than temperatures outside the shaded forests. Additionally, they discovered that this cooling effect was driven by soil moisture with this cooling effect becoming less prevalent as soils become drier.

“The findings are alarming in the context of climate change as more frequent and more severe droughts may threaten the cooling functions of forests,” said Dr. Caroline Greiser, who is a landscape ecologist at Stockholm University and lead author of the study.

Top 9 Cat Longevity Products for 2024

Posted by in categories: food, life extension

Cats already have 9 lives, but what if we could give them 18? Longevity research isn’t just benefiting humans: I looked into some supplements and products that may help you extend your cat’s lifespan, or at least their healthspan.

If you proudly share a house or apartment with one or more cats, chances are you want your precious pet to live a long and healthy life. In addition to getting the basics of diet, exercise, and safety right (basically, do the opposite of the cartoon Garfield), there are many cat longevity products out there that aim to increase your cat’s lifespan.

We’ve taken the time to explore some of them, and this comprehensive list of the top nine cat longevity products is a resource you can use to discover options that may keep that furry feline of yours not only healthy but also happy, energetic, and curious for many years to come.

We Might Have Found a Bacterium Responsible for Depression

Could a fecal transplant pill be the antidepressants of the future?

Depression is real, and it is complex. Most conditions that affect our brain chemistry are going to be complex, and there are no easy, simple answers. We can’t cure depression by just exercising more, eating better, or taking a short vacation to recharge (although there is some evidence that getting more money, especially to lift you out of poverty, helps relieve depressive symptoms).

University of Hawaiʻi Scientists Discover Micrometeorites May Have Delivered Life’s Building Blocks to Earth

Posted by in categories: asteroid/comet impacts, chemistry, existential risks

Micrometeorites, tiny space rocks, may have helped deliver nitrogen, a vital life ingredient, to Earth during our solar system’s early days. This finding was published in Nature Astronomy on November 30 by an international research team, including scientists from the University of Hawaiʻi at Mānoa and Kyoto University. They discovered that nitrogen compounds like ammonium salts are common in material from regions distant from the sun. However, how these compounds reached Earth’s orbit was unclear.

The study suggests that more nitrogen compounds were transported near Earth than previously thought. These compounds could have contributed to life on our planet. The research was based on material collected from the asteroid Ryugu by Japan’s Hayabusa2 spacecraft in 2020. Ryugu, a small sun-orbiting rocky object, is carbon-rich and has experienced considerable space weathering due to micrometeorite impacts and solar charged ions.

The scientists studied the Ryugu samples to understand the materials reaching Earth’s orbit. They used an electron microscope and found the Ryugu samples’ surface covered with tiny iron and nitrogen minerals. They theorized that micrometeorites carrying ammonia compounds collided with Ryugu. This collision sparked chemical reactions on magnetite, resulting in iron nitride formation.

AzTECC71: The Faint Galaxy That Defies Optical Detection

Posted by in categories: cosmology, evolution

Dr. McKinney noted, “With JWST, we can study for the first time the optical and infrared properties of this heavily dust-obscured, hidden population of galaxies because it’s so sensitive that not only can it stare back into the farthest reaches of the universe, but it can also pierce the thickest of dusty veils.”

Did galaxies produce stars in the early universe? This is what a recent study published in The Astrophysical Journal hopes to unveil as a team of international researchers analyze data from NASA’s James Webb Space Telescope (JWST) about a star-forming galaxy called AzTECC71 that existed approximately 900 million years after the Big Bang. What makes this discovery unique is that AzTECC71 is hidden behind a fair amount of dust which initially fooled astronomers to hypothesize that it’s not very big. How astronomers now hypothesize that AzTECC71 was producing a plethora of new stars despite its young age, which challenges previous notions of the formation and evolution of galaxies so soon after the Big Bang.

Enhanced AI tracks neurons in moving animals

Posted by in category: robotics/AI

Recent advances allow imaging of neurons inside freely moving animals. However, to decode circuit activity, these imaged neurons must be computationally identified and tracked. This becomes particularly challenging when the brain itself moves and deforms inside an organism’s flexible body, e.g., in a worm. Until now, the scientific community has lacked the tools to address the problem.

Now, a team of scientists from EPFL and Harvard have developed a pioneering AI method to track inside moving and deforming animals. The study, now published in Nature Methods, was led by Sahand Jamal Rahi at EPFL’s School of Basic Sciences.

Tesla App Update provides improvements to Phone Key and Waypoints

Posted by in category: mobile phones

Tesla is launching the newest version of its App with a new software update, labeled version 4.27.5. A variety of new features are set to roll out, including Phone Key improvements, Waypoints Support, and Supercharger Photos, so drivers know what to expect from their next charging visit.

Tesla’s 4.27.5 App Update will be released on December 5 and features a few new features after 4.27.3 rolled out last week, which featured the first looks at Cybertruck Support after the delivery event last week.

The three features that will be introduced through 4.27.5 are Waypoints Navigation Support, Supercharger Photos, and Phone Key Improvements.
