Scientists from the Oswaldo Cruz Foundation (FIOCRUZ) in Pernambuco discovered a substance that can block Zika virus. However, years of study are still necessary before the 6-methylmercaptopurine riboside (6MMPr) can be turned into a medicine and be produced in large scale. »
A study found that children who slept on average one hour less a night had higher risk factors for type 2 diabetes, including higher levels of blood glucose and insulin resistance. »
As a part of their research to understand the evolution of the human brain and how it differs from those of other primates, scientists from Kent State University discovered proteins associated with Alzheimer's disease -- believed to be unique to humans -- in a sample of brains of aged chimpanzees. »
A new study identifies genes that are necessary in cancer cells for immunotherapy to work, addressing the problem of why some tumors don’t respond to immunotherapy or respond initially but then stop as tumor cells develop resistance to immunotherapy. »
Researchers have found that dopamine-producing neurons are connected with the brain's circadian center. »
Scientists exploring the brain for answers to certain sleep disorders may have been looking in the wrong place, suggests new research. »
Researchers from the National Institute of Mental Health have produced the first direct evidence that parts of our brains implicated in mental disorders may be shaped by a “residual echo” from our ancient past. »
Cells within an injured mouse eye can be coaxed into regenerating neurons and those new neurons appear to integrate themselves into the eye’s circuitry, new research shows. The findings potentially open the door to new treatments for eye trauma and retinal disease. »
A new study suggests that T cells, which help the body’s immune system recognize friend from foe, may play an important role in Parkinson’s disease. »
Tests on deceased former professional American football players showed nearly all of them had a chronic traumatic brain disease, according to scientific research published Tuesday in the JAMA medical journal. »
Scientists at the University of Florida have discovered a new method of observing the brain changes caused by Parkinson’s disease, which destroys neurons important for movement. »
A new high-precision feeding system for lab mice reinforces the idea that the time of day food is eaten is more critical to weight loss than the amount of calories ingested. »
How well cancer patients fared after chemotherapy was affected by their social interaction with other patients during treatment, according to a new study by researchers at the National Human Genome Research Institute and the University of Oxford in the United Kingdom. »
A new study led by scientists at the National Institute on Alcohol Abuse and Alcoholism (NIAAA), part of the National Institutes of Health, demonstrates that aldosterone, a hormone produced in the adrenal glands, may contribute to alcohol use disorder (AUD). »
A new antimalarial candidate could pave the way for a single-dose treatment that boosts malaria eradication when used in combination with other preventative measures. »
