An accurate analog clock tick-tick-ticks with a constant precision and well known frequency: one tick per second. The longer you let it tick, the better to test its accuracy --10 times as long corresponds to a ten-fold i...

Many people get frustrated with technology when it malfunctions or is counterintuitive. The last thing people might expect is for that same technology to pick up on their emotions and engage with them differently as a re...

For the first time (in mice), a new article explains how baby neurons -- precursors called neuroblasts, generated from a permanent pocket of stem cells in a brain area called the V-SVZ -- make an incredible journey from ...

Scientists used muons, a by-product of cosmic rays, to image the interior of the Great Pyramid—and found a previously unknown space inside. Christopher Intagliata reports. --

Bacteria that live in the human digestive tract can influence how cancer responds to immunotherapy, opening a new avenue for research to improve treatment, medical researchers report.

Mexican doctors have safely reused donated pacemakers after sterilization, shows a new study. The findings create the possibility for patients to receive a pacemaker who otherwise could not afford one.

Chromosomes can 'cheat,' biasing the chance that they will make it into a sex cell. Biologists show how this bias arises in female cells, detecting molecular signals that create an asymmetry in the machinery that drives ...

Physicists at Emory University have shown how a system of lifeless particles can become "life-like" by collectively switching back and forth between crystalline and fluid states--even when the environment remains stable.

A new study indicates a potential benefit of the menopausal therapy for a certain type of memory.

Different changes to the microbial community of the stomach may explain why related conditions are associated with different risk levels and types of gastric tumor, according to a new study.

There's nothing new thing under the sun--except maybe light itself.

Mutations in a gene linked to autism in people causes neurons to form too many connections in rodents, according to a new study. The findings suggest that malfunctions in communication between brain cells could be at the...

Up to 5 per cent people who are concussed suffer long-term health problems. Research suggests that bouts of hyperbaric oxygen therapy might help

Mindfulness may offer an active coping mechanism for mothers faced with the stress of having a newborn diagnosed with congenital heart disease (CHD). Mindfulness, which aims to increase a person's awareness and acceptanc...

Even though men use tanning beds at lower rates than women, men who tan tend to do it in riskier ways, according to a new study. The findings should help public health officials rethink how, and to whom, they're targetin...

Scientists have uncovered a promising new therapeutic strategy to repair myelin in the brain. Surprisingly, it's associated with a protein in the blood.

For the first time, researchers have tied several brain circuits to alertness. The findings enhance scientists' understanding of the forces driving alertness, a brain state that's essential to survival, by showing that d...

New research findings raise hopes for developing combination targeted therapy to treat medulloblastoma and other tumors linked to over-activation of an important signaling pathway.

Researchers identified a brain circuit that controls neuron development in the adult brain. It runs from near the front of the brain back to the hippocampus, a learning- and memory-related structure. The finding ultimate...

Molecules called endosiRNAs help us avoid genetic chaos, according to a new study. Much of the human genome contains pieces of DNA called transposons, a form of genetic parasite. When active, transposons can damage genes...

Taking part in regular exercise can reduce fatigue and pain, and improve cardiovascular health and quality of life in women being treated for advanced breast cancer, according to new research.

Scientists have shown that members of Maroon communities in South America -- formed over four centuries ago by Africans who escaped slavery -- have remarkably preserved their African genetic heritage (98 percent). In con...
