Study finds a link between post-traumatic brain activity and an increase in anxiety symptoms six months after a traumatic event.

Moment-to-moment fluctuations in brain activity over a three-minute period can reliably predict how receptive a person with social anxiety will be to cognitive behavioral therapy.

Women with polycystic ovary syndrome (PCOS) who take the contraceptive pill have three-quarters of the diabetes risk as those with PCOS who don't

Memories of objects from stressful situations rely on similar neural activity to memories of the stressful events themselves.

A new study reveals our genes play a key role in how our bodies respond to exercise. Researchers also identified specific genes that influence the outcome of different types of physical activity.

Each person has a specific brain "fingerprint", and that fingerprint changes over the course of our lives, a new study reports.

Those with a genetic predisposition to clinical depression are more likely to exhibit physical symptoms including migraines, chronic pain, and fatigue, researchers report.

How do we make decisions during times when we are uncertain? A new study may have clues. Researchers identified a specific set of neurons that prevent the brain from using unreliable information when faced with decision-...

Everyone has a unique pattern of brain activity and it can be spotted after just 100 seconds inside a brain scanner

A new type of strong, flexible self-healing plastic can repair itself rapidly, even in salty or acidic water, which may be useful for divers or underwater pipes

Researchers at Delft University of Technology have found a new way to cool radio waves all the way down to their quantum ground state. To do so, they used circuits that employ an analog of the so-called laser cooling tec...

Dehumidifiers remove excess moisture from a room, but does a dehumidifier cool a room? We explore the answer here.

Researchers have identified a protein that plays a key role in how the brain regulates appetite and metabolism. Loss of the protein, XRN1, from the forebrain, resulted in obese mice with an insatiable appetite, according...

Valerio Piazza is creating new 3D architectures built from an inventive form of nanowire. His research aims to push the boundaries of miniaturization and pave the way to more powerful electronic devices. He has just won ...

From the internet, to fiber or satellite communications and medical diagnostics, our everyday life relies on optical technologies. These technologies use optical pulsed sources to transfer, retrieve or compute informatio...

A team of fusion researchers at the Department of Energy's Oak Ridge National Laboratory used datasets from measurements on the Joint European Torus, or JET, tokamak to model an improved method for quantifying the amount...

Impurities in the plasmas in fusion tokamaks can reduce performance. These impurities are created by interactions between the hot plasma and the metal tokamak walls. These walls are often armored with tungsten. This mate...

Assistant Professor Kang Hao Cheong and his research team from the Singapore University of Technology and Design (SUTD) have set out to apply concepts from quantum Parrondo's paradox in search of a working protocol for s...

It's widely known that the world has a plastics problem. From landfills to the ocean, the stuff is everywhere, and our conscientious efforts to recycle don't do nearly as much good as we think. What's less widely known i...

EPFL and Microsoft Research scientists demonstrated ultrafast optical circuit switching using a chip-based soliton comb laser and a completely passive diffraction grating device. This particular architecture could enable...

In the search for dark matter particles, a tabletop experiment in the heart of a Canadian mine might do the trick. The SENSEI collaboration uses skipper charged-couple devices, or CCDs, which are the most sensitive senso...

The immune cells, known as microglia, also help regulate blood flow and maintain the brain's critical blood vessels, researchers have discovered. The findings may prove important in cognitive decline, dementia and stroke...
