At the end of a July that broke heat records across the country, a new report released by two California State agencies project that summer months of extreme heat will be the norm by 2060.
A genetic test to predict the risk for prostate cancer could reduce the need for repeat biopsies in men who have previously had negative biopsies.
The hallmark of sunburn – the reddish, painful yet protective immune response from over exposure to ultraviolet (UV) radiation — is a consequence of RNA damage to skin cells, reports a team of UC San Diego School of Medicine researchers and their colleagues.
Scientists from The Scripps Research Institute have shown a single protein can make the difference between an infection clearing out of the body or persisting for life.
Psoriasis is an autoimmune disorder of out-of-control skin cell proliferation. For hard-to-heal wounds, the problem is just the opposite: Restorative skin cells don’t grow well or fast enough. An international team of scientists, led by the UC San Diego School of Medicine, report on a molecule that may lead to new treatments for both conditions.
Roughly 100,000 years ago, human evolution hit a bottleneck: Our ancestors had been reduced to perhaps 5,000-10,000 individuals living in Africa. In time, modern humans would emerge from this population eventually replacing all other evolutionary cousins, such as the Neanderthals.
Scientists at The Scripps Research Institute (TSRI) have unraveled a complex chemical pathway that enables bacteria to form clusters known as “biofilms.” Biofilm formation occurs when bacterial cells adhere to each other and to surfaces as part of their growth cycle or to set up a defense against attack: Cells on the outside of a biofilm are susceptible to antibiotics but protected interior cells are more difficult to kill.
Scientists at The Scripps Research Institute have developed an injectable treatment that can protect mice from an otherwise lethal dose of cocaine. The findings could lead to human clinical trials of a ready-made solution of antibodies — similar to how snakebite is treated — designed to reverse the effects of cocaine in an emergency situation. Currently, cocaine is involved in more than 400,000 emergency-room visits and about 5,000 overdose deaths each year in the United States.
Medical providers can determine if someone is having or has recently had a heart attack, but cannot tell if a patient is on the cusp of having one in the next couple of weeks. This could change in a profound way following a study confirming the presence of abnormally large or misshapen circulating endothelial cells (CEC) in the blood stream in the days leading up to a heart attack.
Evidence uncovered in Florence, Italy supports a theory that a lost Leonardo da Vinci painting resides behind a superimposed mural. At stake, is confirmation of the painting “The Battle of Anghiari,” commissioned in 1503, and considered by some as one of da Vinci’s most significant works.
