For decades scientists have tried to find a way to measure the mass of the lightest matter particle known to exist. Three new approaches now have a chance to succeed In 1980, Hamish Robertson was a tenured professor at M...

A new brain mapping study reveals a neural network in cuttlefish that involves chemosensory function and body pattern control which the cuttlefish utilize for foraging and camouflage.

Researchers say a gene found in many centenarians can reverse the biological age of the heart by ten years. The findings offer a potential target for patients with heart failure.

The Danuri spacecraft arrived in lunar orbit in Dec. 2022, and its first image dump is out of this world.

The second law of thermodynamics is often considered to be one of only a few physical laws that is absolutely and unquestionably true. The law states that the amount of 'entropy'--a physical property--of any closed syste...

Researchers say mindfulness meditation has benefits for adolescents who have experienced trauma.

Panic-induced hyperventilation can reduce our ability to respond to environmental threats as it desensitizes body temperature to change.

Researchers reveal how the olfactory system aids in threat assessment and have identified neurons that learn whether a specific smell represents a threat.

Some patients diagnosed with behavioral-variant frontotemporal dementia (bv-FTD) may instead be suffering from a cerebrospinal fluid leak that leads to brain sagging.

The activation of dentate granule cells in the hippocampus plays a key role in alterations that occur during the development of post-traumatic epilepsy.

Frequent moderate to vigorous exercise is linked to better cognition and brain power during middle age. This intensity level was associated with better working memory and mental processes. Reducing the intensity to lower...

Injecting the brain molecule into mouse models of multiple sclerosis increased the number of oligodendrocytes. The findings suggest fractalkine may help to slow the progression, or potentially halt multiple sclerosis.

Anhedonia and depression arise when POMC neurons in the arcuate nucleus of the hypothalamus become hyperactive as a result of chronic stress. Reducing the activity also reduces feelings of depression and loss of pleasure...

Teenagers who suffer from inadequate or disrupted sleep may be at higher risk of developing multiple sclerosis later in life.

X-rays of a sword that had been sitting in museum storage reveals that it's actually from the Bronze Age.

What is behind dark energy--and what connects it to the cosmological constant introduced by Albert Einstein? Two physicists from the University of Luxembourg point the way to answering these open questions of physics.

Information processing devices such as smartphones are becoming more sophisticated because their information-recording density constantly increases, thanks to advances in microfabrication technology. In recent years, how...

Turbidity currents are cascades of sediment that tumble down Earth's 9000 submarine canyons carrying carbon, plastics and pharmaceuticals into the deep sea. We are finally learning just how often these dramatic events oc...

Research from an international team of scientists has cast new light on the physics of vitrification--the process by which glass forms.

The further out in time, the more unreliable a weather forecast. That's because small variations in initial weather conditions can completely change the entire system, making it unpredictable. Put another way, in the "bu...

Why some mushrooms are bioluminescent remains uncertain, but a study using LED lights adds to the evidence they attract insects that help the fungus disperse its spores

Humanity faces greater existential threats than it did during the Cold War, according to the Bulletin of Atomic Scientists
