Oxygen isn't always a good thing. Of course, people—and most organisms—cannot live without it. But oxygen can also be quite toxic and lead to profound health consequences.

An expedition led by the Royal Canadian Geographical Society in partnership with Woods Hole Oceanographic Institution has obtained the first close-up images of the wreck of Quest, the last ship of famed Antarctic explorer ...

Researchers have developed a new 3D printing technique that allows the printing of whole objects while controlling the temperature of the chemical reaction to stabilize the process. Academics in the University of Nottingham's ...

In a new study, researchers at the Indian Institute of Science (IISc) have resolved a longstanding mystery by showing how epithelial tissues exhibit slow-moving, glass-like behavior despite their fast-paced biological activity. ...

For decades, manufacturing plastic-bonded high explosives, or PBXs, has relied on legacy processes like slurry coating. In this method, explosive crystals are mixed with a binder, a polymer that helps hold the material together, ...

Newly developed microparticles can infiltrate stubborn bacterial matrices and release tiny oxygen bubbles to clean surfaces and wounds more efficiently than hydrogen peroxide or other cleaning agents alone, researchers at ...

For more than 150 years, scientists have debated when and how the Colorado River first carved its way through the Grand Canyon. Now, a new study led by researchers at the University of New Mexico offers evidence that the ...

A single monitoring network developed by McGill, Natural Resources Canada, Université du Québec à Montréal (UQAM) and Dalhousie University researchers can simultaneously track earthquakes, water behavior, human activity and ...

Scientists have identified a promising new strategy to tackle one of the biggest obstacles in treating glioblastoma, one of the most aggressive forms of brain cancer: resistance to chemotherapy. The study shows that an experimental ...

As heat waves continue one after another, we are feeling their effects on our own bodies: It becomes harder for us to function normally. Trees also have their limits when temperatures are too high. Above a certain critical ...

DZNE researchers have uncovered a mechanism that determines why a neuron usually forms a single, long extension called an "axon"—a phenomenon that is fundamental to how our brain functions. Contrary to the common view that ...

For the first time, astronomers have discovered stellar cocoons rich in complex organic molecules within a supernova remnant. A research team from Niigata University, Gifu University, RIKEN and Kyoto University in Japan used ...
