Scientists report that rats exposed to high-energy particles, simulating conditions astronauts would face on a long-term deep space mission, show lapses in attention and slower reaction times, even when the radiation exposure is in extremely low dose ranges.
Scientists have captured an elusive brain signal underlying memory transfer and, in doing so,...
A novel compound that targets an important brain receptor has a dramatic effect against a host...
A study describes a circuit in the brain of fruit flies that controls their daily, rhythmic behavior of rest and activity. It also found that the fly version of a human brain protein is a major coordinating molecule in this circuit.
The National Institutes of Health (NIH) Design Requirements Manual (DRM) is the only comprehensive design requirements and guidance manual for biomedical research laboratory and animal research facilities in the U.S. Compliance with the DRM ensures that NIH owned, leased and funded facilities will be of the highest quality and provides the minimum standards for other institutions around the world.
Australian researchers are trying a novel way to boost the power of cochlear implants: They used the technology to beam gene therapy into the ears of deaf animals and found the combination improved hearing.
Most people think the development of the heart only happens in the womb, however the days and weeks following birth are full of cellular changes that play a role in the structure and function of the heart.
Researchers have done what is believed to be the first direct genetic study to document the important function for the Ron receptor, a cell surface protein often found in certain cancers, and its genetic growth factor, responsible for stimulating cell growth, in the development and progression of IBD.
Researchers have investigated, possibly for the first time in any species, the direct impact of pain on sexual behavior in mice.
Men's susceptibility to serious health conditions may be influenced by low exposure to testosterone in the womb, new research suggests.
Nonsteroidal antinflamatory drugs (NSAIDs) that block an enzyme called COX-2 relieve pain and inflammation but can cause heart attacks, stroke, heart failure, and even sudden cardiac death. This has prompted a decade-plus search for safer, but still effective, alternatives to these commonly prescribed, pain-relieving drugs.
Working with mice and rabbits, Johns Hopkins scientists have found a way to block abnormal cholesterol production, transport and breakdown, successfully preventing the development of atherosclerosis.
Working in a secretive quarantined lab, scientists in the US have discovered a small molecule that saves monkeys and rodents from one of the world's most terrifying viruses.
Scientists have shown new genetic evidence that could strengthen the link between the role of dietary fats and colon cancer progression.
When we get sick it feels natural to try to hasten our recovery by getting some extra shuteye. Researchers found that this response has a definite purpose, in fruitflies: enhancing immune system response and recovery to infection.
There have always been limitations to experiments done on mice, but new technology, which allows scientists to replace mouse genes with human genes, could clear the way for new ground to be broken.
A single type of cell in the lining of the bladder is responsible for most cases of invasive bladder cancer. A study, conducted in mice, is the first to pinpoint the normal cell type that can give rise to invasive bladder cancers.
Although doctors have long known that people with Down syndrome have a heightened risk of developing acute lymphoblastic leukemia (ALL) during childhood, they haven’t been able to explain why. Now, investigators have uncovered a connection between the two conditions.
