Scientists have long puzzled over the planet Mercury's excessively dark surface. New research suggests that carbon from passing comets could be the planet's mystery darkening agent.
An outbreak of a novel Escherichia coli (E.coli) strain resistant to antibiotics has been linked to contaminated endoscopes in a Washington state hospital. The study indicates that industry standard cleaning guidelines, which were exceeded by hospital staff, may not be sufficient for sterilizing endoscopes adequately.
Scientists have developed tiny ‘nanoneedles’ that have successfully prompted parts of the body to generate new blood vessels, in a trial in mice. The researchers hope their nanoneedle technique could ultimately help damaged organs and nerves to repair themselves and help transplanted organs to thrive.
Researchers have discovered that potentially aggressive T-cells that might lead to auto-immune disease can instead be enlisted to help "police" over-active immune responses, via the molecule CD5. This new breakthrough may open the door to design better treatments for autoimmune diseases, they say.
Biomedical researchers have successfully converted microbubble technology already used in diagnostic imaging into nanoparticles that stay trapped in tumors to potentially deliver targeted, therapeutic payloads.
Using a new high-speed, high-resolution imaging method, researchers were able to see blood flow and other functions inside a living mouse brain at faster rates than ever before.
It is widely accepted that, in humans, music confers numerous benefits. An extensive body of research indicates that these benefits extend even to patients under general anesthesia, and include reduced perceived pain, anxiety and stress.
The 2015 elections in Nigeria were chaotic, but the country’s voters displayed immense courage in showing up at all. More than 20 people were killed, not in electoral violence between competing parties but by gunmen who didn’t want the elections to happen at all. A further 23 were rumored beheaded on the eve of the vote. read more
According to research published today, music is beneficial for cats in the surgical environment. But not all music is equal in this respect - cats, it seems, benefit most from classical music. read more
Researchers at NYU Langone Medical Center have captured images of the underlying biological activity within brain cells and their tree-like extensions, or dendrites, in mice that show how their brains sort, store and make sense out of information during learning. read more
Over the last several decades, DNA – the genetic material of life as we know it – has completed a remarkable scientific cycle. In 1953, it was a mysterious blur on an X-ray diffractogram. By the 1970s, it was possible to determine the sequence of short nucleotide chains. Show More Summary
The body's immune system fights disease, infections and even cancer, acting like foot soldiers to protect against invaders and dissenters. But it turns out the immune system has traitors amongst their ranks. Dr. Karin de Visser and her...Show More Summary
The planet Mercury’s puzzlingly dark color could result from its bombardment with carbon-rich micrometeorites, reports a study in Nature Geoscience. This may explain why the Moon is lighter in color than Mercury, even though the Moon’s...Show More Summary
Warming winters have allowed mountain pine beetle outbreaks in the coldest areas of the western United States, but milder winters can't be blamed for the full extent of recent outbreaks in the region, a Dartmouth College and U.S. Forest Service study finds. read more
A new drug that shows potential in laboratory studies against a rare type of acute leukemia has been developed by scientists. And additional studies suggest the same compound could play a role in prostate cancer treatment as well, they say.
A study of peanut consumption showed that including them as a part of a high fat meal improved the post-meal triglyceride response and preserved endothelial function. Vascular dysfunction plays a major role in the development of atherosclerosis and the formation of coronary plaques and lesions that lead to coronary artery disease.
Something as easy as adding more spinach, kale, collards and mustard greens to your diet could help slow cognitive decline, according to new research. The study also examined the nutrients responsible for the effect, linking vitamin K consumption to slower cognitive decline for the first time.
New research into the changing ecology of thousands of shallow lakes on the North Slope of Alaska suggests that in scenarios of increasing global temperatures, methane-generating microbes, found in thawing lake sediments, may ramp up production of the potent greenhouse gas -- which has a global warming potential 25 times greater than carbon dioxide.
A large pilot study of a new bowel cancer screening test has demonstrated a major increase in participation rates across population groups. The new test is called a Fecal Immunochemical Test or FIT for short. In addition to being able...Show More Summary
The five-star ratings of hockey helmets, judging their abilities to help prevent concussions, have been released by experts. The findings so far: Only one of 32 tested hockey helmets earned three stars with all other models faring worse in laboratory impact tests.
