Alien world chemistry found inside meteorite that struck New Jersey home

On July 16, 2024, a daytime meteor shook New York City with a sonic boom as it passed just south of the Statue of Liberty. Now, an international team of researchers reports in the journal Science Advances that a short time later, a meteorite weighing more than 2 pounds crashed through the roof of a house in the town of Hillsborough, New Jersey.

“A forensic study of the fragments revealed that they contained preserved bits from near the surface of a primitive asteroid, where it experienced concentrated salty fluids—a process not previously known from this type of protoplanet world,” said lead author and meteor astronomer Peter Jenniskens of the SETI Institute and NASA’s Ames Research Center in California’s Silicon Valley.

On that day, a rock the size of a heavy airline bag entered Earth’s atmosphere at a speed of 32,000 miles/h (14.4 kilometers per second). Sixty observers from New York, New Jersey, Connecticut, Rhode Island and Pennsylvania reported seeing the meteor to the American Meteor Society, while 16 in New York and New Jersey felt the shock wave.

Asteroid breakup may explain inner solar system bombardment 800 million years ago

A Southwest Research Institute-led study has proposed a connection between a specific collision in the main asteroid belt and an inner-solar-system-wide bombardment episode that may have had measurable biological and geological consequences on Earth. The research suggests that the catastrophic breakup of the Eulalia parent body could be linked to an impact shower that struck the terrestrial planets about 800 million years ago. The work is published on the arXiv preprint server.

“The role impacts have played in shaping the origin and evolution of life in our solar system is poorly understood,” said Dr. William Bottke, an executive director in SwRI’s Solar System Science and Exploration Division in Boulder, Colorado. He also directs the Center for Lunar Origin and Evolution (CLOE), SwRI’s team in NASA’s Solar System Exploration Research Virtual Institute, and is lead author of a paper describing this research. “The heavily cratered surface of the moon serves as a reminder of the large impacts in Earth’s past, but so far, only the Chicxulub impact event 66 million years ago has been strongly linked to a specific effect on life, namely the mass extinction of the dinosaurs.”

Finding geological evidence of impacts older than 650 million years ago on Earth is challenging because of the constant renewal of our home planet’s surface. Earth’s landscape constantly changes as constructive forces such as volcanoes and plate tectonics build it up, while destructive forces such as weathering wear it down. One way researchers have searched for clues about Earth’s past is to study asteroid shower events.

Can We Re-grow You?

For all of medical history, we’ve tried to persuade sick cells to behave better. What if instead we just swapped them out? Can we insert new brain cells grown from your own skin cells? And what does any of this have to do with sending one’s own cells into space, or rescuing animals on the very brink of extinction? Today Eagleman talks with stem cell biologist Jeanne Loring about the exciting next horizons.

The Godfather of AI: A New Species Is Emerging — And We Can’t Stop It | Geoffrey Hinton (Nobel)

In this exclusive, long-form interview, Turing Award laureate Geoffrey Hinton—often called the “Godfather of Deep Learning”—opens up about the promise and peril of advanced AI. Hinton explains why he left Google, how close we really are to artificial general intelligence (AGI), and what guard-rails governments, researchers, and ordinary citizens can put in place today to keep powerful neural networks from going off the rails.

Watch the interview with Yann LeCun on AI and machine learning: • Father of AI: AI Needs PHYSICS to EVOLVE |…

Geoffrey Hinton is a British-Canadian cognitive psychologist and computer scientist best known as the “godfather of deep learning.” As a professor at the University of Toronto and co-founder of Google Brain, he pioneered modern neural networks—work that earned him the 2018 Turing Award alongside Yann LeCun and Yoshua Bengio. Since leaving Google in 2023, Hinton has focused on warning about the societal and existential risks of increasingly powerful AI systems.

Hugo de Garis on AI: Are We Building Gods or Terminators?

In 2012, I sat down with Hugo de Garis, and he told me billions of people could die this century over one question: should we build machines smarter than ourselves?

Back then, it sounded like pure science fiction. He called the coming conflict the Artilect War. On one side, the Cosmists who want to build godlike machine intelligence. On the other hand, the Terrans who would rather go to war than gamble on human extinction. In between, the Cyborgists who just want to become gods themselves. He even had a word for the body count:

Gigadeath.

Fourteen years later, the war he predicted hasn’t arrived. The question underneath it has moved to the center of the room.

Because de Garis got one thing profoundly right, even if the timeline was lurid. The hard part was never whether we could build these systems. It’s whether we should, and who gets to decide. That is not a #technology question. Technology is only ever the How. This is a Why and a What, a question about power, values, and what kind of species we choose to become.

He was asking it when almost nobody else was. That is why this conversation still holds up.

NASA’s Lucy finds a wobbling peanut-shaped asteroid with signs of ancient water

A bizarre wobbling asteroid revealed by NASA’s Lucy mission is exposing hidden clues about ancient water, cosmic collisions, and the origins of the solar system. NASA’s Lucy spacecraft discovered that asteroid Donaldjohanson is a wobbling, peanut-shaped relic born from a violent collision and slowly reshaped by the subtle force of sunlight. It also carries traces of ancient water, making it an important clue to the solar system’s mysterious past.

Even relatively small asteroids can have surprisingly eventful histories. NASA’s Lucy spacecraft recently revealed that asteroid Donaldjohanson is a wobbling, peanut-shaped object that has been shaped by collisions, sunlight, and even a brief encounter with liquid water long ago.

The asteroid formed about 155 million years ago when fragments from a violent collision gradually came together. Since then, a subtle but persistent force generated by sunlight has altered its rotation, while traces of ancient water remain preserved in its rocky surface.

Why Advanced Aliens Probably Don’t Build Dyson Spheres

🫣🤫🤔 Let’s face it: we’re still a Type 0 civilization on the Kardashev Scale… though, to be honest, we’re much closer to the Kardashian Scale 😁 endless entertainment, constant distractions, and celebrity obsession. 🙈🙉🙊 A true Type I civilization would be focused on mastering energy, advancing science, and solving humanity’s biggest challenges. We’ve still got a long way to go! While most people’s main concerns revolve around material comfort, entertainment, and instant gratification, who truly cares about the fate of the most vulnerable? About social exclusion? Inequality? The pollution and destruction of our environment? Who cares about the massive extinction of million of species now underway? Who cares about sustainable development and peace for everyone? A true Type I civilization would be collectively focused on optimizing how it functions and shaping a better future for everyone. We’re still very, very far from that.

How to Survive the Ultimate Cosmic Doomsday

What happens when the laws of the universe turn against existence itself?
In this cinematic 4K documentary, we journey through a hierarchy of cosmic catastrophes that challenge the survival of any civilization, from the localized death of planets to the absolute collapse of physical laws.

▶A Film by: Scienshell Studio.

In a universe governed by deep time and immense forces, disaster is not a matter of if, but when. From worlds frozen in perpetual schizophrenia by tidal locking to the ultimate recollapse of space-time, civilizations must either evolve to engineer the cosmos or face total eradication.

But as the scale of destruction grows, the line between technology and natural law begins to blur. For those who survive the end of the universe, reality itself becomes a blank canvas.

In this video, you’ll discover:
00:00 Introduction.
02:35 Tidally Locked Worlds and Planetary Accelerators.
05:35 Stellar Storms and Planetary Shield.
08:43 Supernovae and Star Lifting.
11:53 Supermassive Black Holes and The Space Nomads.

Is AI the Great Filter?

Artificial intelligence may be civilization’s greatest tool… or its last. Could AI explain why the galaxy seems silent, or does it make the Fermi Paradox even harder?
