Are we all aliens? NASA’s returned asteroid samples hold the ingredients of life from a watery world.
@AssociatedPress reports new research presents "the strongest evidence yet that asteroids may have planted the seeds of life on Earth and that these ingredients were mingling with water almost right from the start."

You can always count on www.BigThink.com for big thoughts. Case in point: This article by astrophysics professor Adam Frank that suggests that life might be more common across the universe than a popular model of cosmic life and intelligence would have you believe. Read for yourself:

Scientists have discovered that comb jellies, one of the oldest animals on Earth, can fuse together. The surprising find has prompted some existential questions among biologists. @CNN has more.

Extraterrestrial life may look nothing like life on Earth, so astrobiologists are coming up with a framework to study how complex systems evolve.
From @ConversationUS: "Astrobiologists have attempted to come up with universal rules that govern the emergence of complex physical and biological systems both on Earth and beyond."

From @LiveScience: Emerging evidence suggests that plate tectonics may have begun much earlier than previously thought — and may be a big reason that our planet harbors life. Some scientists are now arguing that plate tectonics emerged very soon after Earth's formation — perhaps predating life itself. Read more: https://flip.it/9nLsjW

Here's a little something for those of you feeling existential dread today.
From @PopularScience: Without humans, what would happen to Earth? "People have considered versions of this apocalyptic thought experiment for centuries, if not millenia. ... Ideas of human extinction and societal dissolution are rampant in religious texts and myths of ancient cultures."

Are any animals truly "immortal?"
@popsci looks at creatures who defy biological time:
"From tiny jellyfish to one-ton sharks, some animals subvert scientific expectations about aging and death."

Scientists show how sperm and egg come together like a key in a lock.
@AssociatedPress reports: "The team found that three proteins on the sperm join to form a sort of key that unlocks the egg, allowing the sperm to attach. Their findings, drawn from studies in zebrafish, mice, and human cells, show how this process has persisted over millions of years of evolution. Results were published Thursday in the journal Cell."

Will children born today live to 100? Don’t bet on it, researchers say. A new study says that while life expectancy numbers are still inching up worldwide, we’re approaching the upper limit of human longevity. “We’re squeezing less and less life out of these life-extending technologies. And the reason is, aging gets in the way,” says S. Jay Olshansky, a University of Illinois-Chicago researcher who was lead author of the study. Read more from @AssociatedPress.

From @sciencefocus: “If life exists elsewhere in the Solar System, one of the most likely places is Jupiter's moon Europa.” We may find out next month when NASA’s Europa Clipper mission will examine the icy moon to see if it's capable of supporting life: https://flip.it/yyIa3a

Humans have long been fascinated with understanding how life began and evolved on Earth, and modern scientists have made significant advances in answering questions around the origins of life here. A recent study might just have unearthed another piece of the puzzle — the organism from which all living organisms have descended. More for ScienceAlert: https://flip.it/e1gpX8

NASA data suggests there’s liquid water deep beneath Mars’ surface.
From @popsci: "The study suggests that there’s liquid water deep, deep in the Martian crust—at least five miles down, and potentially as far as 15 miles."

The discovery of a possible sign of life in Venus’ clouds sparked controversy four years ago. Now, scientists say they have more proof.
CNN reports: "The data, the researchers say, contains even stronger proof that phosphine is present in the clouds of Venus, our closest planetary neighbor."

@nixCraft You could swap Linux with #life and it would apply just as much.

1. Don't code when you're tired.
2. Don't login as root on your Linux/Unix boxes when you're tired, guys.
3. See # 1 again.
4. With time you will forget these rules again.

Who’s the father? For these baby animals, one doesn’t exist.

Venus wasn’t always hot and uninhabitable. Scientists think the second planet from the sun could have had as much water as Earth billions of years ago, and may have even supported life if any of that water was in liquid form. But researchers have a new theory as to how our neighbor in the solar system lost nearly all of its water and why it may have happened far faster than initially thought. The Conversation has more on the study.

Is life capable of spreading from planet to planet? A pair of astronomers recently proposed a detection strategy based on the concept of panspermia, the idea that life can start on one planet and spread to others by hitching rides on meteorites. More from Live Science: https://flip.it/ef13Z0
