Memories have unique genetic signatures that reveal what they are. The finding could lead to ways to read and alter memories in people with PTSD or phobias

This one's for the books: in a jaw-dropping study, a team just turned the human brain from a read-only memory device to a rewritable one. “What?” you might ask. Of course the brain is rewritable. It's constantly usin...

Mechanical engineers at the University of California, Riverside, have reported success in using inexpensive materials to produce thermoelectric devices that transform low-level waste heat into electricity.

(Penn State) A newly discovered structure of a sodium-based material allows the materials to be used as an electrolyte in solid-state batteries, according to researchers from Penn State and Pacific Northwest National Lab...

A new study in BMJ Case Reports warns of the unexpected consequences of participating in hot chili pepper eating contests.

Researchers reveal later school start times improve sleep quality in children.

Bad news for life near Proxima Centauri - the star has been seen emitting explosive blasts of radiation that would destroy the ozone on its Earth-like planet

Researchers report nitric oxide plays a key role in regulating neural function. The findings shed new light on how neurodegeneration may occur.

A new study reveals our brains process weak visual stimuli better in the evenings and mornings than during daylight hours. Researchers say the transition from light to dark has greater influence on visual perception than...

According to folklore, earwigs like to crawl through the ears of sleeping humans, burrow into their brains, and lay eggs. Perhaps for this reason, or maybe because of their large rear-end pinchers, these insects tend to ...

Researchers at the National Institute of Standards and Technology (NIST) have created a chip on which laser light interacts with a tiny cloud of atoms to serve as a miniature toolkit for measuring important quantities su...

Researchers have published a new research framework that defines Alzheimer's disease by brain changes, not symptoms.

Metamaterials researchers at Duke University have demonstrated the design and construction of a thin material that can control the redirection and reflection of sound waves with almost perfect efficiency.

Researchers have successfully induced the sensations of touch and movement in the arm of a paralyzed man, with the help of a tiny array of electrodes implanted into the somatosensory cortex.

When power generators like windmills and solar panels transfer electricity to homes, businesses and the power grid, they lose almost 10 percent of the generated power. To address this problem, scientists are researching ...

Tuberculosis is both deadly and difficult to test for. But a new paper suggests rats might make the illness easier to sniff out.

The movement of thousands of electrons underlies electronics. Yet, ubiquitous as electrons are, the particulars of their behavior continue to stump physicists. One phenomenon has proven especially puzzling: how electrons...

A new method of using light to scan the human body, developed by researchers at the University of St Andrews, could result in less intrusive and more effective diagnosis for patients. The work is the result of a collabor...

Factoring very large numbers into their prime "building blocks" is extremely difficult for classical computers, and this difficulty underlies the security of many cryptographic algorithms. While it's easy to factor the n...

Reactions in solar panels, catalytic converters, and other devices are governed by the quick motion of electrons. To capture the movement of these electrons, scientists use pulses of extremely high energy x-rays. The cha...

A team of physicists at the University of Sussex are developing the science to create a safe and efficient 'paint' that can reveal, with terahertz (THz) radiation, the contents of luggage or objects hidden in clothing.

A German study casts doubt on the story that automation will destroy jobs. Could it be true elsewhere?
