Plant-based diets are recommended to reduce the risk of heart disease; however, some plant-based diets are associated with a higher risk of heart disease, according to a new study.

To respond to stress optimally, the body needs to produce glucocorticoid hormones, such as cortisol, extremely quickly. New research has revealed the molecular network that enables rapid glucocorticoid production within ...

After decades of arguing whether junk DNA exists, a study has calculated that without it we'd all have to reproduce in huge numbers to escape harmful mutations

Scientists have teamed up to evaluate the tools used to probe the cancer genome. Their work classifies and describes the strengths and weaknesses of more than 20 algorithms developed by independent research groups.

The first exoplanet was spotted in 1988. Since then more than 3,000 planets have been found outside our solar system, and it's thought that around 20% of Sun-like stars have an Earth-like planet in their habitable zones....

Elon Musk has urged a gathering of governors to regulate artificial intelligence now, before potentially dangerous outcomes start occurring.

Doctors in England recently removed 27 contact lenses from a woman's eye, according to a new case report.

Here's why elephants can't run as fast as cheetahs.

An animal's maximum speed is based on how fast it can accelerate, which explains why the largest animals are not the fastest

From cheetahs to the Peregrine falcon to slippery squid, the animal kingdom is full of speedy organisms built for their environment.

More than a third of Americans don't get enough sleep, and growing evidence suggests it's not only taking a toll on their physical health through heart disease, diabetes, stroke, and/or other conditions, but hurting thei...
