Scientists have developed a new biological tool for examining molecules - the building blocks of life - which they say could provide new insights and other benefits such as reducing the numbers of animals used in experiments.

For the first time ever, astronomers at The University of New Mexico say they've been able to observe and measure the orbital motion between two supermassive black holes hundreds of millions of light years from Earth - a ...

Many geckos inhabit trees, often living high in the canopy. Relying on their incredible adhesive strength to help them break their fall, they jump from trees, and land on either leaves or relatively smooth tree trunks. How ...

(Phys.org)A pair of researchers, one with the Weizmann Institute of Science in Israel the other with Princeton University in the U.S. has come up with a possible explanation for the inability of space scientists to find ...

Building transient electronics is usually about doing something to make them stop working: blast them with light, soak them with acid, dunk them in water.
