In 2017, a gigantic iceberg designated A-68 split from the Larsen C ice shelf, giving scientists a unique opportunity: access to an extensive region of the seabed that had previously…

Scientists have conclusively identified a source in the Milky Way that can accelerate protons to some of the highest energies known in our galaxy. The discovery could help researchers better…

Betelgeuse, Betelgeuse, Betelgeuse: somewhat like summoning the homophonically named movie character, astronomers had hoped that repeated studies of this iconic red supergiant star would reveal its long-suspected stellar companion. Now,…

If you’ve never had to endure the relentless clamor of tinnitus, the distress is hard to imagine. Many sufferers report a mental health nosedive after the condition begins – and,…

A growing body of research suggests that Alzheimer’s disease may be influenced by biological changes occurring far beyond the brain. New findings now point to metabolic health, especially obesity, as…

Engineers designing nuclear fusion reactors have lived with an infuriating paradox for decades: the plasma conditions that best trap heat inside a reactor tend to be precisely the conditions that…

On Aug. 2, 1971, a lunar liftoff was televised for the first time. Apollo 15 astronauts David Scott and James Irwin spent three days on the moon before departing in…

The “hat” tile is a mathematical wonder. Discovered by amateur mathematician David Smith in 2022, it can be used to cover every square inch of an endless bathroom floor (or…

Dark matter is usually described as an invisible substance that responds only to gravity. But scientists are now exploring a more complex possibility: dark matter particles may also interact through…

With microplastics (plastic fragments less than 5 mm or 0.2 inches in size) being discovered in multiple parts of the body – including bones and the brain – the question…

China has made a breakthrough in its pursuit of commercial nuclear fusion after completing the world’s largest superconducting magnet for its next-generation “artificial sun” program in Hefei, the capital of…

For decades, scientists have theorized that kids actually need to get a bit dirty for their immune systems to develop fully. It’s known as the ‘hygiene hypothesis‘. And, as childhood…

A new machine-learning approach that examines brain activity during sleep may help identify people with an elevated risk of developing dementia. The research was led by scientists at UC San…

An international research team has found that primordial black holes may trigger white dwarf stars to explode as Type Ia supernovae. These unusual explosions could also help explain a chemical…

Artificial sweeteners are in the news almost constantly. If you believe the headlines, they are terrible blights on our health that are far worse than the sugar they replace. This…
