Atrial fibrillation is one of the most common kinds of arrhythmia, causing the heart not to contract properly in order to pump the blood, which can lead to the formation of thrombi (blood clots) and the consequent associated ...

The gene variant posing the greatest genetic risk of late-onset Alzheimer's disease (AD) is called APOE-ε4. A different variant of the same gene, APOE-ε2, is thought to confer protection against AD.

Spaceflight takes a physical toll on astronauts, causing muscles to atrophy, bones to thin and bodily fluids to shift. According to a new study published in the journal PNAS, we can now add another major change to that list. ...

Durotomy is a common neurosurgical complication involving a tear in the dura mater, the protective membrane surrounding the brain and spinal cord. Damage can cause cerebrospinal fluid (CSF) leakage, leading to delayed healing, ...

Researchers at University College London (UCL) have uncovered a key mechanism that helps the body switch off inflammation—a breakthrough that could lead to new treatments for chronic diseases affecting millions worldwide.

An international team of astronomers, including researchers from the Department of Physics at The University of Hong Kong (HKU), has uncovered the first decisive evidence that at least some fast radio burst (FRB) sources—brief ...

For decades, scientists have been counting annual growth rings—similar to tree rings—inside fossilized leg bones of Tyrannosaurus rex to estimate how old the giant carnivores were when they died and how quickly they grew ...

The phenomenon where electron spins align in a specific direction after passing through chiral materials is a cornerstone for future spin-based electronics. Yet, the precise process behind this effect has remained a mystery—until ...

Scientists have uncovered the mummified remains of cheetahs from caves in northern Saudi Arabia.

In a study published in the Journal of Archaeological Science: Reports, Dr. Ellery Frahm and his colleagues analyzed two unusual blue-green glazed ceramic sherds discovered in the Gobi Desert in 2016.

Each year, more than two million people die from advanced chronic liver disease (ACLD). Previous research has linked gut microbiome disruptions to this condition and suggested that bacteria typically found in the mouth may ...

Researchers at the Department of Energy's Oak Ridge National Laboratory are pioneering the design and synthesis of quantum materials, which are central to discovery science involving synergies with quantum computation. These ...
