Some physical injuries and neurological conditions can temporarily or permanently impair movement, leaving some people unable to speak, type on keyboards or use electronic devices. Brain-computer interfaces (BCIs), systems that can decode brain activity patterns and convert them into computer commands or written text, could be of great value for paralyzed patients.

Despite their potential, most of the best-performing BCIs developed ...

Imagine trying to swallow a sip of water while your face feels stuffed with congestion, your sense of taste is dulled and your body is floating 250 miles (400 kilometers) above Earth.

That scenario is part of everyday life for astronauts aboard the International Space Station.

Spaceflight changes the human body in dramatic ways. Muscles shrink, bones lose density and bodily fluids shift toward the head. Astronauts often return with puffy faces, stuffy noses and a feeling similar to a lingering cold. When you’re congested, you might have more difficulty swallowing—but does microgravity also affect this important body function?

As a speech-language pathologist and researcher who studi...

High-salt (HS) intake is a major global health concern, closely linked to hypertension and growing evidence of cognitive and emotional decline. Although salt is a routine part of daily diets, long-term overconsumption can negatively affect both the cardiovascular system and the central nervous system, underscoring the need for practical dietary strategies to mitigate these adverse health effects.

Prostaglandins (PGs) are lipid compounds derived from arachidonic acid (AA) that act as potent local hormones...

IBM and researchers from the University of Chicago announced a demonstration in quantum computing that meets the fundamental criteria for “quantum advantage”—the point where quantum computers can be confirmed to have outperformed classical computers on trusted computations.

The collaboration said its system had performed computations beyond the reach of leading classical simulation methods while providing confidence that the computation returned accurate results.

In their new paper, the researchers showed th...
