Extinction cascading through ecosystems could spell trouble for humans
Humans rely on nature extensively for everything from food production to coastal protection, but those contributions might be more threatened than previously thought, according...
New perovskite LED emits a circularly polarized glow
Light-emitting diodes (LEDs) have revolutionized the displays industry. LEDs use electric current to produce visible light without the excess heat found in traditional light...
New proteins ‘out of nothing’
Proteins are the key component in all modern forms of life. Hemoglobin, for example, transports the oxygen in our blood; photosynthesis proteins in the...
Astronomers detect a black hole on the move
Scientists have long theorized that supermassive black holes can wander through space—but catching them in the act has proven difficult.

Traces of Earth’s early magma ocean identified in Greenland rocks
New research led by the University of Cambridge has found rare evidence -- preserved in the chemistry of ancient rocks from Greenland -- which...
Health risk? More than 500,000 Americans live within 3 miles of natural gas flares
More than a half-million Americans are exposed to oil and gas "flaring" events—the burning off of excess natural gas at production sites—resulting in potentially...
Shivering in the Pleistocene: New analyses of prehistoric climate conditions map human adaptations to...
Jesús Rodríguez and Ana Mateos, scientists at the Centro Nacional de Investigación sobre la Evolución Humana (CENIEH), working with the geographer Christian Willmes of...
Controlled by light alone, new smart materials twist, bend and move
Researchers at Tufts University School of Engineering have created light-activated composite devices able to execute precise, visible movements and form complex three-dimensional shapes without...
Scythian people weren’t just nomadic warriors, but sometimes settled down
Scythian people of ancient Ukraine led more complex lives than commonly assumed, according to a study published March 10, 2021 in the open-access journal PLOS...
IceCube detection of a high-energy particle proves 60-year-old theory
On December 6, 2016, a high-energy particle hurtled to Earth from outer space at close to the speed of light. The particle, an electron...
How a ladybug warps space-time
Researchers at the University of Vienna and the Austrian Academy of Sciences, led by Markus Aspelmeyer have succeeded in measuring the gravitational field of...
