The Ocean Observatories Initiative has been collecting data on physical, chemical, geological and biological conditions in the Atlantic and Pacific Oceans for the past decade

Astronauts Sophie Adenot of ESA (European Space Agency) and Jack Hathaway of NASA, both Expedition 74 flight engineers, look out a window in the cupola.

From dementia to heart attacks, hearing loss has been linked to a wide range of effects across the body, and the condition is on the rise. Fortunately, we're learning how best to safeguard this crucial sense and how we might be able to reverse the damage

Computer simulations have uncovered a new manganese compound that could exist deep in Earth’s mantle and may be connected to the process that gave our atmosphere oxygen

3I/ATLAS has caused quite a stir over the last year, inviting astronomers to update what they know about other solar systems as well as our own. However, this third interstellar visitor may have an unexpected impact on our understanding of dark matter. A new paper, available in pre-print on arXiv from researchers at the University of Hamburg, attempts to calculate the impact that the presence of large amounts of interstellar objects (ISOs) would have on our calculation of dark matter in our galaxy.

An exploration of how biological cooperation underpins all life - and why we’ve overlooked its power until now - makes thrilling reading, finds Penny Sarchet

A group of researchers have proposed rules to prevent artificial intelligence from overpowering humans in math

Where did stars, and light itself, come from? Is there a hidden sector of particles and forces called “dark energy” affecting the cosmos?

By encoding mathematical statements into numbers, mathematician Kurt Gödel used ordinary arithmetic to check whether a statement can be proved

The dwarf planet Ceres has a surface that seems to get more perplexing with each new study. A recent paper presented at EGU26 in Vienna only adds to its mystery.

The Trump administration has fast-tracked research into psychedelics, and experts say it is likely a matter of time before the drugs are used to treat minors

The JWST found an abundance of overmassive black holes at high redshifts, pushing the limits of black hole (BH) science in the early Universe. Results have claimed that these BHs are significantly more massive than expected from the BH mass-host galaxy stellar mass relation derived from the local Universe. But new research shows they were just outliers in the normal range of masses that don't require any special causes.

The upper galaxy might be more photogenic, but the lower galaxy is more unusual.

Multi-billion dollar space telescope programs aren’t only feats of aerospace engineering. They also feature “lies, damn lies, and statistics”. Or at least statistics. They definitely feature those, as does all good observational astronomy. The problem with statistics is, in order to get a clear definitive answer, you need lots of samples. And, to put it mildly, it’s hard to find lots of samples of planets with alien life on them. And even harder to prove that the signals we think are caused by alien life aren’t caused by some other non-biological process. Or at least that’s the theory underpinning a new paper available in pre-print on arXiv from David Kipping of Columbia University (and Cool Worlds YouTube fame).

The universe is full of fascinating structures, and some of the most striking take shape inside the giant clouds where stars are born. There, streams of gas appear to converge from all directions toward a dense central hub, like spokes meeting at the center of a wheel. New simulations show why this is, and why star formation overall is so inefficient.

Some clinics are touting pressurized oxygen chambers as a treatment for long COVID, but the evidence is mixed
