People with higher exposure to traffic-related air pollution were more likely to have high amounts of amyloid plaques in their brains associated with Alzheimer's disease after death, according to a new study. Researchers looked at fine particulate matter, PM2.5, which consists of pollutant particles of less than 2.5 microns in diameter suspended in air.
The iconic baleen whales, such as the blue, gray and humpback whale, depend on sound for communication in the vast marine environment where they live. Now researchers have for the first time found that baleen whales evolved novel structures in their larynx to make their vast array of underwater songs.
The drug finasteride, also known as Propecia or Proscar, treats male pattern baldness and enlarged prostate in millions of men worldwide. But a new study suggests the drug may also provide a surprising and life-saving benefit: lowering cholesterol and cutting the overall risk of cardiovascular disease.
For many genetic diseases, disabling or editing a gene using CRISPR is insufficient to overcome the effects of the underlying genetic mutation. A corrective gene needs to be added to the genome to fix the problem. Researchers have discovered a way to use a bird retrotransposon -- a type of junk DNA -- to insert […]
Scientists have discovered that the immune system stalwart I B has a moonlighting gig. A tiny protein sequence within I B activates another family of key immune proteins called POUs. The discovery may point to a new drug target for various autoimmune disorders.
Hundreds of novel ingredients never encountered by human physiology are now found in nearly 60 percent of the average adult's diet and nearly 70 percent of children's diets in the U.S. An emerging health hazard is the unprecedented consumption of these ultra-processed foods in the standard American diet. This may be the new 'silent' killer, […]
