What if you found out that you could heal using only a finger? It sounds like science fiction, reminiscent of the 1982 movie "E.T." Well, it turns out that your body's own cells can do something similarly unexpected. Researchers ...

Algorithms and lasers tame chemical reactivity

Researchers have developed an algorithm for photochemistry, bringing the burgeoning field a step closer to the goal of using different colors of light like a switch to activate a range of different chemical reactions in one ...

Tracking cosmic ghosts

The idea was so far-fetched it seemed like science fiction: create an observatory out of a one cubic kilometer block of ice in Antarctica to track ghostly particles called neutrinos that pass through the Earth. But speaking ...

Researchers grow most lifelike bone yet from woven cells

Imagine using stem cells from your bone marrow to grow a piece of bone tissue in the lab, after which medical doctors explore which drugs have the desired effect on your bones. In this way, a tailor-made treatment plan would ...

Controlling the speed of light bullets

Though it sounds like something straight out of science fiction, controlling the speed of light has in fact been a long-standing challenge for physicists. In a study recently published in Communications Physics, researchers ...
