Gravitational lens (noun, “Graah-vih-TAY-shun-ul LENZ” verb, “gravitational lensing”)This effect occurs when gravity bends light from a distant object. If there is only empty space between the eye and, for instance, a faraway supernova (the huge explosion of a dying star) that supernova might be too faint to see. But if there is a big galaxy — a large cluster of stars — between the astronomer and...

Plants turn out to be secondhand smokers. They breathe in smoke, nicotine and other pollutants released by burning tobacco. And that can be a good thing for people. By sharing our environment with green plants, people may be able to breathe easier. But can plants that people eat also suck up pollutants? Yes, a new study finds. And that may explain why nicotine has been found in some herbal teas,...

The Ebola epidemic still ravaging West Africa has sickened an estimated 26,000 people so far. More than 10,800 of these people have died. A new study points to why caring for these dead can be dangerous: Their corpses remain infectious for 7 days.That’s the suspicion, anyway. The new study was not conducted with dead people. Instead, researchers studied macaques that took part in Ebola research....

A special coating for spacecraft that is blacker than even the inky darkness of space. Artificial muscles powering minuscule motors. Ultra-tiny sponges sopping up major oil spills. These are just some of the up-and-coming uses for exceptionally small structures assembled from individual carbon atoms. While it may sound like the stuff of science fiction, it’s actually science fact — or will be...

Learning some concepts in chemistry can require a lot of studying. It can be hard to memorize chemical reactions and keep track of atoms — the basic units of chemical elements — and their building blocks. A great way to learn some of this is to make the work a game — as in Ion. It’s a new card game.Ions are atoms or molecules that have electric charge due to losing or gaining electrons. Those...

The world’s best timepiece just got even better.Last year, U.S. government scientists announced they had developed the world’s most accurate clock. Now, a year later, they report having modified this atomic clock. The improvements mean it should not lose or gain a second for 15 billion years. That is as much time that has elapsed since, well, the dawn of time. The changes make the clock about...

We’ve all heard it — that loud “Crack!” when someone pulls on stiff knuckles. But what happens to make that sound? It’s something that scientists have puzzled over for decades. A new study has now used a high-speed camera to watch what happens to the joint. That popping sound comes from the formation of a bubble in the fluid between two bones in the finger, it finds.And these new data may just ...
