Coral Die-Off Marks Earth’s First Climate ‘Tipping Point’, Scientists Say

By Jeff Tollefson & Nature magazine

The total solar eclipse in North America on April 8, 2024, temporarily reset the biological clocks of some bird species, according to new research.

The eclipse created a dramatic spectacle…

Astronomers have long called Uranus and Neptune the “ice giants” because models suggested that these outer planets’ interiors are largely made of mixtures of water, ammonia and other ices — compounds that freeze easily in deep space. But new…

Scientists have discovered huge, mysterious pieces of DNA in the oral microbiome — the population of bacteria and other microbes living in our mouths — and they say this giant DNA might influence the human immune system.

It’s well known that…

In 2006 immunologist and 2025 Nobel prize winner Shimon Sakaguchi co-wrote an article in Scientific American that now feels prophetic. In the story, entitled “Peacekeepers of the Immune System,” Sakaguchi traced a time line of important…

Then she kind of asked me, “Do you think I could be an astronaut?” I mean, technically, you don’t need your legs, and so on and so forth. When I realized that she meant New Shepard, I said, ‘Well, let me talk to people I…

Scientists have grown embryo-like structures in the laboratory that produced human blood cells, raising new possibilities for regenerative medicine.

The ability to generate blood stem cells in the laboratory may one day make it possible to treat…

A “Big One” on the Cascadia subduction zone in the Pacific Northwest might trigger a similarly serious earthquake on California’s San Andreas Fault, new research suggests.

The findings are based on sediments taken from the seabed off the coast of…

As frustrating as having an atmosphere can be for physicists, it’s just as bad for astronomers, who have to deal with clouds, atmospheric absorption of certain wavelengths, and other irritations. One of the less obvious effects is the…

An artificial intelligence (AI) model has revealed never-before-seen geological structures at Italy’s Campi Flegrei volcano, including a clear “ring fault” that could unleash magnitude 5 earthquakes.

So far in 2025, Campi Flegrei has produced…
