Uranus and Neptune are hiding something big beneath the blue

Space and time from Science Daily Feed - Wed, 12/10/2025 - 7:50am
Uranus and Neptune may not be the icy worlds we’ve long imagined. A new Swiss-led study uses innovative hybrid modeling to reveal that these planets could just as easily be dominated by rock as by water-rich ices. The findings also help explain their bizarre, multi-poled magnetic fields and open the door to a wider range of possible interior structures. But major uncertainties remain, and only future space missions will be able to uncover what truly lies beneath their blue atmospheres.

Extracorporeal Blood Oxygenation and Ozonation

Science-based Medicine Feed - Wed, 12/10/2025 - 6:36am

There is an entire industry catering to people who, as Webb once famously said on the hilarious Homeopathic A&E skit, have “more money than sense.” This is the so-called “wellness” industry, now supercharged by an online army of “wellness influencers”. At first approximation, this entire industry is basically a scam. That may sound unfair, but it is built into its very essence. […]

Scientists discover a new state of matter at Earth’s center

Space and time from Science Daily Feed - Wed, 12/10/2025 - 5:32am
New research reveals that Earth’s solid inner core is actually in a superionic state, where carbon atoms flow freely through a solid iron lattice. This unusual behavior makes the core soft, matching seismic observations that have puzzled scientists for decades. The mobility of these light elements may also contribute energy to Earth’s magnetic field. The findings reshape models of Earth’s interior and could apply to other rocky planets.

The Primordial Black Hole Saga: Part 3 - Primordial Ooze

Universe Today Feed - Wed, 12/10/2025 - 4:07am

The early universe was a pretty intense place to be. And not just “early” as in a few billion years ago. I mean early early, just a few seconds after the Big Bang. The universe is small, less than a meter across. It’s hot, with temperatures so high it doesn’t even make sense to say them – they’re just stupidly high numbers with no connection to our everyday existence.

The British Robots Bringing Heavy Industry to Orbit

Universe Today Feed - Wed, 12/10/2025 - 4:03am

The UK is actively trying to support the infrastructure to make it a significant player in the coming age of the space economy. It recently received 560 proposals to it’s National Space Innovation Program, and handed out £17M in grants to 17 different organizations following five main themes. One of those is an effort by the University of Leicester and The Welding Institute (TWI) to develop a robotic welder for use in repairing and manufacturing in space, as described by a new press release from the university.

A 50 Million Light Year Structure Caught Spinning

Universe Today Feed - Wed, 12/10/2025 - 3:34am

Astronomers have discovered a filament 50 million light years long containing hundreds of galaxies, all spinning together. This immense structure, located 140 million light years away, challenges current models of galaxy formation by showing that large scale rotation can persist far longer and more coherently than theories predicted. The discovery offers a rare glimpse into how galaxies acquire their spin and reveals the Cosmic Web as a more dynamically active place than previously imagined.

Did ancient humans start farming so they could drink more beer?

New evidence suggests that alcohol was a surprisingly big motivator in our monumental transition from hunting and gathering to farming – but was beer really more important to us than bread?

How Mars Controls Earth's Climate

Universe Today Feed - Wed, 12/10/2025 - 1:28am

A new study reveals that Mars plays a surprisingly crucial role in Earth's climate cycles, with new simulations showing that the mass of our planetary neighbours directly controls the timing and intensity of Milankovitch cycles that drive ice ages. By varying Mars's mass from zero to ten times its current value in computer models, researchers discovered that a more massive Mars strengthens the ~100,000 year climate cycles and creates the 2.4 million year "grand cycle" that influences Earth's long term climate. This finding demonstrates that Earth's climate rhythms are connected to the gravitational structure of the inner Solar System, not just the Sun and Moon.

Euclid Reveals What Wakes Sleeping Black Holes

Universe Today Feed - Wed, 12/10/2025 - 1:27am

The European Space Agency's Euclid telescope has delivered an unprecedented set of observations of one million galaxies that shows that galaxy collisions play a dominant role in awakening supermassive black holes from their sleep. Using revolutionary AI-powered analysis methods, astronomers discovered that merging galaxies contain up to six times more active black holes than isolated galaxies, with the most luminous black holes found almost exclusively in collision zones.

James Webb catches a giant helium cloud pouring off a puffy planet

Space and time from Science Daily Feed - Tue, 12/09/2025 - 11:10pm
Astronomers using the James Webb Space Telescope have captured dramatic helium streams pouring off the super-puff exoplanet WASP-107b, revealing a world with an enormously inflated, weakly bound atmosphere under intense stellar heat. The detection of helium, water, and various chemical compounds—alongside the surprising absence of methane—paints a picture of a planet that formed far from its star but later migrated inward, where scorching radiation now strips its gases into space.

Scientists reveal a tiny brain chip that streams thoughts in real time

Computers and Math from Science Daily Feed - Tue, 12/09/2025 - 8:54pm
BISC is an ultra-thin neural implant that creates a high-bandwidth wireless link between the brain and computers. Its tiny single-chip design packs tens of thousands of electrodes and supports advanced AI models for decoding movement, perception, and intent. Initial clinical work shows it can be inserted through a small opening in the skull and remain stable while capturing detailed neural activity. The technology could reshape treatments for epilepsy, paralysis, and blindness.

The Longest GRB Ever Detected Is An Intriguing Puzzle

Universe Today Feed - Tue, 12/09/2025 - 11:56am

In July 2025, telescopes detected a gamma-ray burst (GRB) that lasted seven hours. Most GRBs last only milliseconds, or a few minutes. Only a handful have lasted longer than that, and July's GRB was the longest ever detected. It hints at a new, exotic type of explosive event, and astronomers have a few candidates.

I do not need “likes”

Why Evolution is True Feed - Tue, 12/09/2025 - 10:00am

I do appreciate readers “liking” posts or comments, but the problem is that each one generates an email to me, and there are many of them. The result is that my inbox is even more clogged up than usual, and that sometimes makes me miss messages.  So I’ll kindly ask readers to please refrain giving “likes.” If you especially appreciate a post or something I said, please show it by leaving it in the comments after a post, or sending me an email if you want direct contact. Many thanks!
