The interplanetary comet 3I/ATLAS is remarkably rich in a specific type of water that contains deuterium, meaning it came from somewhere colder and with lower levels of radiation than our early Solar System.

NASA's MSL Curiosity rover found a bathtub ring-like deposit of zinc, manganese, and iron in Gale Crater. These metals precipitate out of water in the right conditions, and there's not really any other way they could've become concentrated here. Adding to the excitement, these deposits also form in lakes on Earth, where the concentrated metals are food for some types of bacteria.

During the Cretaceous, 19-metre-long predatory octopuses swam the seas, and evidence from their fossilised remains suggest they may have been highly intelligent hunters

A powerful AI kept from public access because of its ability to hack computers with impunity is making headlines around the world. But what is Mythos, does it really represent a risk and might it even be used to improve cybersecurity?

Neutrinos are very difficult to detect. And when they are detected, pinpointing their sources is likewise difficult. New research shows that the most energetic neutrino ever detected must have had an extraordinarly energetic source. It could even be primordial.

Infecting mice with RSV, a common virus that causes cold-like symptoms, prevented breast cancer cells from reaching their lungs. This was due to the release of proteins that stop viruses from replicating in the lungs also making it harder for cancer cells to seed new tumours

Dr. Jay Bhattacharya is fully of contempt and vitriol for doctors who worked in hospitals, but he literally “loves” lockdowners.

One of the most dramatic and memorable scenes from Interstellar comes from Miller’s planet - and if you don’t want a spoiler for an 11 year old movie, feel free to skip to the next paragraph. When the crew arrives on this potential new home for humanity, they are faced with a literal 1.2 km high wall of water bearing down on them quickly. It’s a great representation of how waves on other planets can act differently than on Earth. Admittedly, according to Kip Thorne, the scientific advisor for that movie, those waves are actually caused by the planet’s proximity to a local black hole rather than the wind that forms our waves here.

Physicists have taken a major step toward using AI not just to analyze data, but to uncover entirely new laws of nature. By combining a specially designed neural network with precise 3D tracking of particles in a dusty plasma—a strange “fourth state of matter” found from space to wildfires—the team revealed hidden patterns in how particles interact. Their model captured complex, one-way (non-reciprocal) forces with over 99% accuracy and even overturned long-held assumptions about how these forces behave.

It breaks my heart to have to report this, but somehow Vashti and her brood of seven ducklings vanished from Botany Pond sometime after Tuesday morning, and have not been seen since.

I have no idea what happened. They were last seen at the pond during Tuesday’s morning rain showers, with the brood warmly tucked under Vashti’s belly.  Now: no ducks—not a trace. The only one left is Armon, who swims disconsolately around the pond and refuses food. He has lost his family.

It was probably not predators: no bodies were found. I’ve ascertained that no workpeople were in the pond during the week.  Either someone scared them away or they walked away, something that hasn’t happened before.

Whatever is the case, the ducklings will probably perish, as the nearest body of water is too far away for little ones to walk.

The members of Team Duck and I are devastates. The seven ducklings were healthy, Vashti was being a great mother, and even Armon stepped up to protect the brood. The invading undocumented drakes left the brood alone. Everything promised a great duck season, and I was looking forward to helping the little ones grow up into adult mallards.

That, it seems, is not to be. This portends to be The Year Without Ducklings.

One side is scorched to over 200 degrees, while the other is plunged into a darkness so cold it falls below minus 200. Welcome to TRAPPIST-1b and 1c, two rocky worlds that have just revealed the first ever climate maps of Earth sized planets beyond our Solar System. The James Webb Space Telescope has been watching, and what it found tells us something profound about where life might, and might not exist in our Galaxy.

At the heart of our Galaxy lurks a supermassive black hole four million times the mass of our Sun. For decades, astronomers have watched mysterious gas clouds drifting towards it on almost identical paths, wondering where they came from and why. Now, a team of researchers think they have finally cracked the puzzle and the answer involves two massive stars locked in a violent embrace!

Scientists are grappling with a cosmic mystery: why does the Universe behave differently on massive scales compared to our own solar system? While distant galaxies reveal clear signs of something bending the rules of gravity—often attributed to dark energy or a hidden “fifth force”—everything nearby seems to follow Einstein’s playbook perfectly.

A breakthrough in brain-inspired computing could make today’s energy-hungry AI systems far more efficient. Researchers have engineered a new nanoelectronic device using a modified form of hafnium oxide that mimics how neurons process and store information at the same time. Unlike conventional chips that waste energy moving data back and forth, this device operates with ultra-low power—potentially slashing energy use by up to 70%.

An international team led by Monash University has uncovered evidence of a rare form of exploding star, helping to shed light on one of the most cataclysmic events in the universe. At the end of their lives, most massive stars collapse into black holes—objects with gravity so strong that not even light can escape. But some are completely destroyed in pair-instability supernova explosions. This can explain the so-named "Forbidden Gap" in black hole masses.

Bill Maher’s “New Rules” segment from the week before last is about AI, its history, its dangers, and its errors.  Maher doesn’t think too much of it, for, after all, AI can’t cure cancer.  I think he gives these bots overly short shrift, and neglects the productive things AI really can do.  But he then implies that it’s run by sociopaths and could drive humanity extinct.

The guests for that week were journalist Kara Swisher, politician Rahm Emanuel, and attorney and security advisor Jake Sullivan.

MSL Curiosity found 7 new organic molecules preserved in Martian sandstone. While they aren't proof that life existed on Mars, they are important. They show that the planet is capable of protecting ancient biosignatures from radiation and preserving them in rock.
