A winking coronary sign refers to the partial collapse of an artery situated over the ventricular septal rupture during systole and refilling of the same during diastole, which is seen as phasic filling and disappearance of the arterial segment during coronar…
It may sound surprising, but when times are tough and there is no other food available, some soil bacteria can consume traces of hydrogen in the air as an energy source.
A team from the University of Illinois has quantified the plant cell properties in two C4 species, including cell shape, chloroplast size, and distribution of cell-to-cell connections called plasmodesmata, providing information that can change how people mode…
NEW YORK, May 18 — Soon, you might only need to blow into a breathalyser to find out if you have Covid-19 or other, more serious diseases like cancer and diabetes. A team of US...
New experiments using one-dimensional gases of ultra-cold atoms reveal a universality in how quantum systems composed of many particles change over time following a large influx of energy that throws the system out of equilibrium. A team of physicists at Penn…
Earlier this year, Saturn lost its long-standing status as "moon king" to Jupiter after 12 new moons were added to the gas giant's 83 known satellites. But Jupiter's victory was short-lived. The ringed planet has reclaimed the title with the discovery of 62 a…
What makes some materials carry current with no resistance? Scientists are trying to unravel the complex characteristics. Harnessing this property, known as superconductivity, could lead to perfectly efficient power lines, ultrafast computers, and a range of …
A new paper discusses how light interacts with theoretical objects called "topological solitons" — kinks in the fabric of space-time that look just like black holes.

Do you look at this image and think ‘river’?NASA's Perseverance rover is getting a closer look at an area of Mars that scientists believe was once an ancient...
Back in 2020 astronomers observed a red nova, which while enormously powerful, is on the low side of energetic events in the universe. Now an astronomer has studied the event in close detail and has come to the conclusion that we have just witnessed a star de…
NASA and the U.S. Navy are testing with a giant disorientation device if certain head movements can ease motion sickness some astronauts and pilots experience.
Several areas of physics suggest reasons to think that unobservable universes with different natural laws could lie beyond ours. The theoretical physicist David Kaplan talks with Steven Strogatz about the mysteries that a multiverse would solve.
Evidence left in rocks is leading scientists to rethink what watery environments looked like on ancient Mars. New images from NASA's Perseverance rover reveal evidence of a powerful river on Mars, possibly deeper and faster-moving than previously known. The i…
