Nutritional supplements taken to boost athletic performance can pose risks to the heart, according to a recent statement.

Researchers have created a gear-shaped photonic crystal microring that increases the strength of light-matter interactions without sacrificing optical quality. The result is an on-chip microresonator with an optical quality factor 50 times better than the prev…

A new analysis of lung transplantations performed nationally in the U.S. shows significant help for patients with severe, irreversible lung damage from COVID-19.

The drugs behind the new pills to treat COVID-19 remain very effective against the omicron variant of the virus in lab tests, according to a new study. However, lab tests also showed that the available antibody therapies -- typically given intravenously in hos…

The Omicron variant of SARS-CoV-2 diverged from previous SARS-CoV-2 variants as a result of adaptive evolution, in which beneficial mutations are passed on to future generations through natural selection, rather than through recombination between previous vari…

In adults who had previously received a full regimen of any of three COVID-19 vaccines granted Emergency Use Authorization (EUA) or approved by the Food and Drug Administration (FDA), an additional booster dose of any of these vaccines was safe and prompted an…

A new study has illuminated an important process that occurs during cell division and is a likely source of DNA damage under some circumstances, including cancer.

Resuming non-contact physical activity 72 hours after a concussion is safe, and may also reduce symptoms and the risk of delayed recovery, suggests the first and largest real-world, randomized clinical trial on the topic to be conducted with children and youth…

Blocking a key protein found in Anopheles gambiae mosquitoes -- the principal vector for malaria transmission to humans in Africa -- could thwart infection with malaria parasites and thus prevent them from transmitting the parasites to humans, according to a n…

Regular physical activity significantly changes the body's metabolite profile, and many of these changes are associated with a lower risk of type 2 diabetes, a new study shows. The study population included more than 7,000 men who were followed up for eight ye…

Families with young children who have type 1 diabetes use insulin pumps that require a lot of effort to operate. Scientists have shown in a clinical trial that automated insulin delivery is safe and effective even at the age of one to seven years.

A robot has performed laparoscopic surgery on the soft tissue of a pig without the guiding hand of a human -- a significant step in robotics toward fully automated surgery on humans.

Researchers have demonstrated that a novel combination of two drugs that act as targeted inhibitors, delivered in a nanoparticle formulation, extend the survival of mice with medulloblastoma. The research team believes this laboratory success could be translat…

A study compared two-week blocks of low-intensity training and high-intensity interval training in terms of performance and recovery. Both methods can improve endurance performance in recreational athletes after already two weeks when the training load is incr…

A study reports the discovery of a molecule with significant potential to disable the COVID-19 virus. The molecule was identified using high-throughput virtual screening -- a search through a library of 6.5 million in-stock compounds that could quickly be scal…

New research suggests that chemotherapy could better target brain tumors in mouse models when it was administered at night instead of during the day. That's because the blood-brain barrier was more likely to allow the chemotherapy to pass through it at night. …

Researchers exploring dementia-related proteins in the brain identified Apolipoprotein E (ApoE) as a key misfolded protein.
