Epithelial cells are the tiny shields that line and protect our bodies. In a developing embryo, epithelial cells grow, divide and move into positions to form the outer layers of our skin and the surfaces of our organs and ...
Iron is essential. Our cells need it to produce energy, carry oxygen throughout the body and power countless chemical reactions that sustain life. But this metal has a dark side. When too much of it is left free inside cells, ...
How many sharks should a coral reef have? It sounds like a simple question, but almost nowhere on Earth is there a reef that has not at some time been fished or otherwise affected by humans, so there is no yardstick against ...
ETH researchers have used a sustainability program for cocoa cultivation in Côte d'Ivoire to demonstrate that, in one in four cases, data was manipulated to meet the program's requirements. If the auditor were aware of the ...
Made entirely of muscle, with no rigid skeleton, muscular hydrostats like octopus arms, elephant trunks and human tongues can move in ways traditional mechanical systems cannot. Between crawling across the seafloor, picking ...
For several years, climate scientists have shown that the Atlantic Meridional Overturning Circulation (AMOC) could come to a halt if the world warms too much. New research from Utrecht University shows that this picture is ...
Astronomers have captured an unprecedented image of a cosmic recycling project in progress—fragments of a dying star being busted up, stripped and absorbed into interstellar space.
The building blocks of rocky planets may have begun forming just 100 million years after the Big Bang—long before the first galaxies even existed—according to new research from the University of Portsmouth.
New research involving the University of Liverpool has provided comprehensive insights into the largest flood event in Europe over the past millennium—the flood traditionally known as "St. Mary Magdalene's Flood" of 1342.
In the image above, a faint trail of stars can be seen stretching across the galaxy. These structures, known as globular cluster stellar streams, are coherent stellar structures that retain a record of their dynamical history ...
