A new discovery upsets biological definition of life, from Anton Petrov:


0:00 Defining life, bacteria vs viruses
1:50 Smallest organisms we think are alive
4:40 First blurred boundary
5:55 Viruses that are almost life
7:00 These viruses make their own proteins!
9:15 What this implies in regards to viruses
10:00 How did this happen?

I was looking around on YouTube for some videos to do with the iconic 1952 Miller-Urey biochemistry experiment and I stumbled across this Anton Petrov video about then new discoveries (He uploaded it on November 2021) concerning it:


Hello and welcome! My name is Anton and in this video, we will talk about a very important discovery about the 1952 Origin of Life Miller-Urey Experiment

The oldest unsolved genetics case in humans, why left-handedness exists:


Half a million years ago, prehistoric humans were already using their left hands to craft stone tools and paint cave walls. Fast forward to the modern day, and that percentage hasn't budged. Despite centuries of being labeled "sinister" or having their hands tied in classrooms, 10 percent of the population remains left-handed. This isn't just a biological quirk; it is a high-precision evolutionary strategy that has survived every attempt at cultural suppression.​
In this video, we open the oldest unsolved case in human genetics. Why does natural selection maintain a trait that seemingly offers no survival advantage? Why do identical twins with the exact same DNA differ in handedness 75 percent of the time? From the "Combat Advantage" theory to a unique cognitive architecture that produces world leaders and elite architects, we explore why being a minority is actually a high-precision evolutionary design.​

An interesting video from New Scientist concerning how prime-numbers may not be random:


The seemingly random distribution of prime numbers has confounded some of the best mathematical minds for centuries. But the Riemann hypothesis, which relates to the zeros in a mathematical function, may hold the answer. It appears to show exactly where we can expect a prime number to appear, the only problem is, no one has yet been able to prove the hypothesis.​
In this video we'll explore prime numbers, explain the enigmatic zeta function and show how this mathematical proof may reveal a deeper truth about the universe.

A video about a 250 year long project reestablish Scotlands ancient Caledonian forest initiated in 1986 so 210 years to go:


Scotland Planted 2 Million Trees Where a Forest Died — What's Growing Back Doesn't Look Real​
In 1986, Scotland’s ancient forest had been reduced to less than one percent of its original size. The Highlands looked natural… but they were actually the result of centuries of deforestation so complete that people forgot a forest had ever existed there.​
One man proposed a two hundred fifty-year plan to bring it back, and just thirty five years later, something unexpected began to happen.​
This video explores how the Caledonian Forest restoration project is rebuilding an entire ecosystem from near extinction. What started as a small volunteer effort planting trees by hand has evolved into one of the most ambitious rewilding projects in Europe. Over two million native trees have been planted, but the real story is what followed.​
As grazing pressure was reduced and ecosystems began to recover, biodiversity returned faster than predicted. Underground fungal networks started reconnecting. Soil began storing more carbon. And in one of the most powerful signals of ecological recovery, golden eagles returned and successfully raised chicks in areas where they hadn’t nested for decades.​
We break down the science behind this transformation: how ecosystems rebuild from the ground up, why long-term restoration requires centuries, and what happens when you stop preventing nature from healing itself.​
• How Scotland’s native forest collapsed to just one percent of its original range
• The two hundred fifty-year plan to restore an entire ecosystem
• The return of golden eagles as a signal of ecological recovery
This channel explores ecological restoration, rewilding, and the hidden systems bringing life back to ecosystems we once thought were lost.

Iceland's trying the same, but it's challenge. I suppose they'll be looking at the long term too.

What do you do if you're lost in a forest in Iceland?

Stand up.

Cladosporium sphaerospermum, found growing in the destroyed Chornobyl reactor, not only endures ionising radiation, it seems to like it. It might even conduct some sort of analogue of photosynthesis on gamma rays - 'radiosynthesis.'


From links in the article:


C. sphaerospermum excels, but other melanised fungi at least put up with radiation.


Thought has turned to how it might be used as living radiation shielding in space.



Before we get hopes too high, they estimate that an effective fungal shield would have to be 2.3m thick and only a bit more Martian regolith would do the trick. It's early days yet though (some of those papers date back a few years) and maybe a way to refine and concentrate pure melanin shielding could be developed?

On a side note, 'mycotecture' is the use of fungus as a building material.


And really far off, in his 'Instrumentality of Mankind' series, Cordwainer Smith proposed oysters as living shielding for spacecraft.

Simulating the present of a Tyrannosaurus Rex on modern Africa:


I Simulated A T.Rex In Modern Africa, Chaos Followed
What happens when the most powerful land predator to ever exist is dropped into a world that was never built for it?
In this video, we simulate a Tyrannosaurus rex surviving in modern Africa’s Serengeti ecosystem—a place filled with apex predators, brutal heat, and prey that has evolved for 66 million years without it.
At first, you dominate.Your size, your bite, your presence—everything forces the ecosystem to react.
But Africa doesn’t just let things exist.It tests them. It adapts. And eventually… it pushes back.From hyenas and lions to elephants, hippos, and disease, this is a deep, scientifically grounded breakdown of what would actually happen if a T. rex tried to survive in the modern world—and why being the apex predator might not be enough.This isn’t Jurassic Park.This is reality.And reality doesn’t care how powerful you are.

First Dawn has a video out about how prehistoric humans survived a solar super-flare:


This video examines Miyake Events, rare bursts of cosmic radiation caused by powerful solar activity. First identified through sudden increases in carbon-14 preserved in ancient tree rings, these events date back to at least 774–775 CE and 993–994 CE, with evidence suggesting even older occurrences in prehistory. Researchers in dendrochronology and astrophysics link them to extreme solar proton events or possible super flares far beyond anything recorded in modern times.​
By analyzing isotopic anomalies in wood and ice cores, scientists can reconstruct how these radiation surges altered Earth’s atmosphere, potentially triggering ozone depletion and widespread auroral phenomena. Some hypotheses suggest that prehistoric humans may have witnessed intense atmospheric disturbances, though the exact environmental and biological impacts remain under investigation.​
The physics behind these events reveals a sobering reality. Our Sun is capable of far greater violence than previously assumed, and modern infrastructure would be highly vulnerable. The next Miyake-scale event is not a question of if, but when.

It looks like America's most toxic lake has turned into a valuable resource, from PBS Terra:


America’s most toxic lake may also be one of its most overlooked resources. At the Berkeley Pit Superfund Site, scientists are extracting clean energy materials from a century of mining waste.
 
It looks like America's most toxic lake has turned into a valuable resource, from PBS Terra:

Reminds me of a story of a dude who bought a parcel of land that had been used for disposal of immense quantities of some industrial base, like sodium bicarbonate (but don't quote me on that). Pennies on the dollar kind of price due to the "waste"

Whatever the industrial base was, it was critical for dealing with certain other industrial wastes, and so this dude has a billion tons of neutralizing agents for free.
