Strokes can leave lifelong lingering issues, as neurons are damaged and die. But now, researchers at the University of Pittsburgh have identified a new drug that could help prevent damage even after a stroke, with tests in mice showing promise.

Classical physics describes how large objects and systems work on an everyday scale, while quantum physics describes the “spooky” subatomic world. Now scientists have observed a rare crossover where a quantum fluctuation affected a macroscale object.

A research team working to unravel the secrets of the gut microbiome has happened upon a specific signature of bacterial species that can be used to detect liver fibrosis and cirrhosis with an accuracy of greater than 90 percent.

Julien's Auctions is offering a trio of historic Apollo 11 artifacts as part of its Legends & Explorers auction. Three of the hand controllers used to steer the Columbia spacecraft are expected to fetch between US$80,000 and $200,000 each.

Researchers have developed an ultrafast-acting form of insulin that promises to work up to four times faster than current formulations. The novel drug has only been tested in animals so far but the researchers hope to test it in human trials soon.

Astronomers have discovered the intact, exposed core of a gas giant locked in a close orbit around a Sun-like star. The discovery will give astronomers a rare opportunity to probe the heart of an ancient alien world.

What would Earth’s climate naturally be doing if it weren’t for human intervention? Researchers have now analyzed 12,000 years of climate data, and found that human-induced warming interrupted and reversed a long-term natural global cooling period.

Researchers have developed a new electrode component for vanadium redox flow batteries that is said to outperform current solutions, thanks to the inclusion of an ingredient found in shrimp shells called chitin.

MRSA is a common and quite dangerous hospital infection that’s resistant to many drugs. Now researchers have developed a new treatment path that targets not the bacteria itself, but the toxins they produce. Tests on mice have proved promising so far.

University of Pennsylvania scientists have demonstrated how a glowing dye can be used to light up cancer cells in tumors and the lymph nodes of dogs, which they say offers hope for improved surgical outcomes in humans.

A new study has solved a long-standing mystery of how acute stress seems to amplify inflammatory disease, despite the fact many stress hormones actually suppress the immune system. It found a specific immune cell is released by fat cells when stressed.

New imaging research is offering insights into the relationship between Alzheimer’s and abnormal accumulations of iron in the brain. The study confirms a correlation between high iron deposits in some brain regions and rates of cognitive decline.
