Negative pressure is a rare and challenging-to-detect phenomenon in physics. Using liquid-filled optical fibers and sound waves, researchers have now discovered a new method to measure it. In ...

When scientists study how materials behave under extreme conditions, they typically examine what happens under compression. But what occurs when you pull matter apart in all directions simultaneously?

For diseases that travel through the air, like COVID-19, special hospital rooms are essential for controlling pathogens and making sure they stay contained to one patient’s room, rather than infecting ...
