Physical rehabilitation and symptom management still remain the mainstay of treatment for stroke, as clot removal or dissolution is effective only within a narrow time frame after the stroke. After that, many patients are ...

Neural tissue normally dies quickly without oxygen. Yet bird retinas—among the most energy-demanding tissues in the animal kingdom—function permanently without it. This may be relevant in future treatment of stroke patients.

According to a new study by the University of Würzburg, Bavarian meadows are the most monotonous insect habitats. Surprisingly, fields and settlements often offer more diversity than grassland.

Researchers have reported new experimental results addressing the origin of rare proton-rich isotopes heavier than iron, called p-nuclei. Led by Artemis Tsantiri, then-graduate student at the Facility for Rare Isotope Beams ...

By resurrecting a 3.2-billion-year-old enzyme and studying it inside living microbes, researchers at the University of Wisconsin–Madison have created a new way to improve our understanding of the origins of life on Earth ...

Nano-sensors that work without batteries or wires could pave the way for more comfortable, less obtrusive sleep and health care monitoring at home, according to scientists at the University of Surrey.

The asteroid that struck the Earth 66 million years ago devastated life across the planet, wiping out the dinosaurs and other organisms in a hail of fire and catastrophic climate change. But new research shows that it also ...

Sweeping winds of vaporized metals have been found in a massive cloud that dimmed the light of a star for nearly nine months. This discovery, made with the Gemini South telescope in Chile, one half of the International Gemini ...

A clinical study shows that preoperative dynamic susceptibility contrast (DSC) perfusion magnetic resonance imaging (MRI) can help predict how microbubbles will distribute in the human brain. This is a key step toward optimizing ...

It's one of astronomy's great mysteries: how did black holes get so big, so massive, so quickly. An answer to this cosmic conundrum has now been provided by researchers at Ireland's Maynooth University (MU) and reported today ...

During pregnancy, maternal and fetal cells migrate back and forth across the placenta, with fetal cells entering the mother's bloodstream and tissues. They can settle in maternal organs such as the thyroid, liver, lungs, ...

A research team at Université Laval may have discovered why physical exercise and living in favorable socioeconomic conditions reduce the risk of depression. In lab animals exposed to chronic social stress, one of the main ...
