The physical interaction between two or more systems, also known as coupling, can give rise to unique and unexpected effects. In the field of optics, coupled light sources (e.g., lasers) can influence each other, produci...

Humans have vestigial ear muscles that once helped our ancestors focus on sounds. New research shows these muscles still activate when we strain to hear in noisy environments. Scientists used electromyography to measure ...

Scientists have used advanced X-ray phase-contrast tomography (XPCT) to uncover how gut health may influence Alzheimer's disease. The study found structural changes in the gut of Alzheimer's-affected mice, revealing abno...

A large study analyzing over 1.1 million pregnancies found no strong evidence that maternal health conditions during pregnancy cause autism. Instead, nearly all previously reported associations between maternal diagnoses...

Wandering salamanders pump their toes full of blood before lifting their feet, a trick that may help them release their sticky grip while conserving energy

The FDA has approved Journavx, an oral medication for treating pain that doesn't target the brain like addictive opioids.

DeepSeek's V3 and R1 models took the world by storm this week. Here's why they're such a big deal.

Global warming is helping rats thrive in major cities around the world, with Washington DC seeing the fastest growth in rats

A nasal spray that contains esketamine -- a potent derivative of ketamine -- can now be taken on its own to treat adults with severe depression, the FDA says. Here's what that means.

We're launching a commenting system on our site -- here's how to join the conversation on Live Science.

A team of engineers, physicists and computer specialists at Canadian company, Xanadu Quantum Technologies Inc., has unveiled what they describe as the world's first scalable, connected, photonic quantum computer prototyp...

The remains of Alexander the Great may lie under the streets of Alexandria, they may have been "eaten by a shark," or they may be somewhere else entirely. But one thing is certain: Archaeologists don't agree.

Alexander the Great died at age 32, but his cause of death is unclear. What killed him has been a long-standing source of debate.

Antimony is widely used in the production of materials for electronics, as well as metal alloys resistant to corrosion and high temperatures.

A new fungus that infects cave spiders and turns them into "zombies" was discovered in a Victorian gunpowder store at Castle Espie in Northern Ireland during filming for a TV show.

The gigantic coronal hole is blasting high-speed solar wind toward Earth, potentially igniting vibrant auroras and minor geomagnetic activity on Jan. 31.

Researchers at the Accelerator Laboratory of the University of Jyväskylä, Finland, precisely measured atomic masses of radioactive lanthanum isotopes and found an interesting feature in their nuclear binding energies. ...

Rather than helping each other out when they're attacked, plants may have to eavesdrop on each other to know when to launch their own defenses.

A mechanism that activates specific muscles in our ears is a leftover from our evolutionary past, back when our ancestors depended more on their hearing for survival.

Challenging centuries-old assumptions about thermodynamics, a new study in published in Physical Review Letters has shown that it is theoretically possible to design a heat engine that achieves maximum power output while...

In a new study published in Nature Physics, researchers have developed the first controlled method for exciting and observing Kelvin waves in superfluid helium-4.
