New evidence suggests volcanoes caused biggest mass extinction ever
Researchers say mercury buried in ancient rock provides the strongest evidence yet that volcanoes caused the biggest mass extinction in the history of the...
Gravitational echo phenomenon will become a key to the new physics,...
Gravitational echoes may be caused by the collision of two black holes, and may indicate that these objects have completely new physical properties. This...
Best in snow: New scientific device creates electricity from snowfall
UCLA researchers and colleagues have designed a new device that creates electricity from falling snow. The first of its kind, this device is inexpensive,...

Need for social skills helped shape modern human face
As large-brained, short-faced hominins, our faces are different from other, now extinct hominins (such as the Neanderthals) and our closest living relatives (bonobos and chimpanzees), but...
Tiny fragment of a comet found inside a meteorite
A tiny piece of the building blocks from which comets formed has been discovered inside a primitive meteorite. The discovery by a Carnegie Institution...
To protect stem cells, plants have diverse genetic backup plans
Despite evolution driving a wide variety of differences, many plants function the same way. Now a new study has revealed the different genetic strategies...
The discrete-time physics hiding inside our continuous-time world
Scientists believe that time is continuous, not discrete—roughly speaking, they believe that it does not progress in "chunks," but rather "flows," smoothly and continuously....
Breezing through the space environment of Barnard’s Star b
The closest exoplanet to us, if we include only single stars like the Sun, is the planet around Barnard's Star, Barnard's Star-b ("BSb"). (The...
