“Deep Space of the Cosmos” –There’s a Mysterious Energy Latent In It Which Can Tell Us About Our Fate 

“Empty space seems to be nothing to us. By analogy, water may seem to be nothing to a fish – it’s what’s left when you take away all the other things floating in the sea. Likewise, empty space is conjectured to be quite complicated,” Martin Rees, Astronomer Royal and Emeritus Professor of Cosmology and Astrophysics at the University of Cambridge.

Large-Hadron-Collider Scientists Embrace AI in Search for a New Physics of the Universe (Today’s Top Science Headline)

 

“My goal is to try to come up with a really new way to look for new physics” — one driven by the data rather than by theory, says Sascha Caron of Radboud University Nijmegen in the Netherlands, who has led the push for the approach at ATLAS. General searches are to the targeted ones what spell checking an entire text is to searching that text for a particular word. These broad searches could realize their full potential in the near future, when combined with increasingly sophisticated artificial-intelligence (AI) methods.

Most Astonishing Conclusion of Modern Physics –“Time Does Not Exist” (Today’s Top Space Headline)

 

“What do we know about time? Language tells us that it “passes”, it moves like a great river, inexorably dragging us with it, and, in the end, washes us up on its shore while it continues, unstoppable. Time flows. It moves ever forwards. Or does it? Poets also tell us that time stumbles or creeps or slows or even, at times, seems to stop. They tell us that the past might be inescapable, immanent in objects or people or landscapes. When Juliet is waiting for Romeo, time passes sluggishly: she longs for Phaethon to take the reins of the Sun’s chariot, since he would whip up the horses and “bring in cloudy night immediately”. When we wake from a vivid dream we are dimly aware that the sense of time we have just experienced is illusory.”

“The Great Void” — In a Massive Region of Space, Astronomers Find Far Fewer Galaxies Than Expected

 

Scientists have known that more than 12 billion years ago, about 1 billion years after the Big Bang, the gas in deep space was, on average, much more opaque than it is now in some regions, although the opacity varied widely from place to place. But they weren’t sure about what caused those variations.

Today’s “Planet Earth Report” –The Great Elephant Cancer Mystery: ‘They Have a Zombie Gene 20x That of Humans’

“We can use the tricks of evolution to try to figure out when this defunct gene became functional again,” said Vincent Lynch, Ph.D., assistant professor of human genetics at the University of Chicago. “It seems to have emerged around the time when the fossil record indicates that the small groundhog-sized precursors of today’s elephants began to grow bigger. This started about 25 to 30 million years ago. This supplementary method of suppressing cancer may have been a key element enabling enormous growth, which eventually led to modern elephants.”

“Scientist Discovers a New Form of Life” –The Genius Who Changed the Way We Think About the Origin of Life (Today’s Top Science Headline)

 

“We are not precisely who we thought we were. We are composite creatures, and our ancestry seems to arise from a dark zone of the living world, a group of creatures about which science, until recent decades, was ignorant. Evolution is trickier, far more complicated, than we realized. The tree of life is more tangled. Genes don’t just move vertically. They can also pass laterally across species boundaries, across wider gaps, even between different kingdoms of life, and some have come sideways into our own lineage — the primate lineage — from unsuspected, nonprimate sources. It’s the genetic equivalent of a blood transfusion or (to use a different metaphor preferred by some scientists) an infection that transforms identity. They called it ‘infective heredity.'”

“The Oldest Flying Creature?” Rare Pterosaur Discovered at 200-Million-Year-Old Watering Hole

 

In a patch of Utah desert no larger than a living room, scientists working a decade ago discovered a late Triassic treasure trove: 18,000 bones from nine unusual species of reptiles, all victims of a watering hole that dried up some 201 million to 210 million years ago. Now, they’re reporting on the most interesting find to date: the oldest ever pterosaur. The find is especially unusual because ancient flying reptiles of that era were thought to live in coastal areas.

“Rerun the Tape of Evolution” –DNA, RNA, ATP, Krebs Cycle– and Life Would Probably Arise Again (Here or In Distant Worlds)

 

 

Charles Cockell, an astrobiologist at the University of Edinburgh and Director of the UK Center for Astrobiology and author of The Equations of Life: How Physics Shapes Evolution views the topic of life’s construction through the lens of someone who is trying to understand how life on Earth can serve as a test case for the nature of possible life elsewhere in the universe.
