Studies since the start of the pandemic have noted that pigs exposed to the coronavirus don't show clinical signs of disease nor do they transmit the virus to other animals. Scientists have uncovered important clues that...

In boys with undescended testis, the risk of developing infertility is traditionally predicted based on a decrease in germ cell count observed using testicular biopsy samples. However, the process of testicular biopsy ca...

Researchers at PSI have compared the electron distribution below the oxide layer of two semiconductors. The investigation is part of an effort to develop particularly stable quantum bits--and thus, in turn, particularly ...

A new study simulated the transmission of SARS-CoV-2, the virus that causes COVID-19, on a flight from London to Hanoi and on another flight from Singapore to Hangzhou.

New research conducted at Lawrence Livermore National Laboratory (LLNL) explores the expansion of a classical mechanics model, that has been useful for understanding asymmetries in inertial confinement fusion (ICF) implo...

The presence of friends increases arousal when people are exposed to scary stimuli, researchers report. Additionally, the stronger the response to the initial stimuli, the more fear response increases when exposed to sub...

The more connected people feel toward each other, the quicker they are to respond to one another in a conversation.

Missing enzymes may cause troublesome knots to appear in DNA.

An artificial pancreas is helping protect very young children with type 1 diabetes at a particularly vulnerable time of their lives. A study published today found that it is both safe to use and more effective at managin...

A spellbinding new video captures a Gentoo penguin's point of view as it feasts on a giant ball of sardines alongside diving albatross and cormorants.

Older adults who are socially isolated are more likely to have missing teeth--and to lose their teeth more quickly over time--than those with more social interaction, according to a new study of Chinese older adults.

Destroying senescent cells in the aging stem cell niche enhances hippocampal neurogenesis and cognitive function in mice, researchers report.

In 2011, the nuclear accident at Fukushima, Japan, resulted in the deposit of radioactive cesium (radiocesium) into habitats in the vicinity. A decade after the accident, researchers have collated the complicated dynamic...

The experiment was intended to assess the safety of such transplants, prior to them being tested in clinical trials.

A newly designed compact device for recording brain activity has a customizable configuration and could help people with restricted mobility regain control of their limbs or provide advanced warnings of epileptic seizure...

An experiment, performed by Istituto Nazionale di Ricerca Metrologica (INRIM) on 200 km of the Italian Quantum Backbone, in collaboration with Toshiba Europe, shows that coherent laser interferometry considerably improve...

New research shows that specific enzymes can remove lactic acid marks. This finding may increase our understanding of cancer medicine and how physical exercise, among other things, can affect human epigenetics.

By mapping all the protein interactions of a dementia-linked protein in the brain called Tau, a team of investigators has created a road map for identifying potential new treatment targets for Alzheimer's disease and rel...

A study has found that patients with cancer who receive chemotherapy -- and some targeted therapies, such as CDK4/6 inhibitors and therapies targeted at B cells -- may mount an inadequate immune response to COVID-19 vacc...

An investigational cancer drug that starves tumors of their energy supply also shows evidence of improving whole body metabolism, leading to improved weight control, according to a new study in mice.

An oral supplement intended to stimulate a natural body process appears to promote muscle endurance and mitochondrial health in humans. New research suggests that the supplement, urolithin A, may help improve or prolong ...

Scientists from the Graduate School of Engineering Science at Osaka University used optical tweezers for the first time inside superfluid helium. With a strongly focused beam of light, they demonstrated the stable trappi...
