A central tenet of biology may need updating given new measurements of start codons by researchers working at NIST.
Listeria, a common food-borne bacterium, may pose a greater risk of miscarriage in the early stages of pregnancy than appreciated, according to researchers at the University of Wisconsin-Madison School of Veterinary Medicine studying how pathogens affect fetal development and change the outcome of pregnancy.
Cancer mortality rates vary considerably within the growing Hispanic population in the United States, with significant differences among the major Hispanic ethnic groups.
The amyloid dye Thioflavin T emerged as the superstar when age researchers in three independent laboratories tested ten already-promising pro-longevity chemicals across a range of distinctive strains and species of tiny nematode worms known as Caenorhabditis. The project, dubbed the Caenorhabditis Intervention Testing Program (CITP), tackled reproducibility, which has been a lingering problem in age research, given that some of the field's most prominent research findings cannot be replicated by other labs.
Scientists from India have discovered seven new frog species belonging to the genus Nyctibatrachus, commonly known as Night Frogs. This find is a result of five years of extensive explorations in the Western Ghats global biodiversity hotspot in India. Four out of seven of the new species are miniature-sized frogs (12.2-15.4 mm), which can comfortably sit on a coin or a thumbnail. These are among the smallest known frogs in the world.
A tiny snail may offer an alternative to opioids for pain relief. Scientists at the University of Utah have found a compound that blocks pain by targeting a pathway not associated with opioids. Research in rodents indicates that the benefits continue long after the compound have cleared the body.
Eating fish and seafood with higher levels of mercury may be linked to a higher risk of amyotrophic lateral sclerosis (ALS), according to a preliminary study released today that will be presented at the American Academy of Neurology's 69th Annual Meeting in Boston, April 22 to 28, 2017. However, fish and seafood consumption as a regular part of the diet was not associated with ALS.
Last year, headlines in The New York Times, The Atlantic, Scientific American and other outlets declared that a decades-old paleontological mystery had been solved. The 'Tully monster,' an ancient animal that had long defied classification, was in fact a vertebrate, two groups of scientists claimed. Specifically, it seemed to be a type of fish called a lamprey. The problem with this resolution? According to a group of paleobiologists led by the University of Pennsylvania's Lauren Sallan, it's plain wrong.
An experimental malaria vaccine protected healthy subjects from infection with a malaria strain different from that contained in the vaccine, according to a new study.
DNA, the stuff of life, may very well also pack quite the jolt for engineers trying to advance the development of tiny, low-cost electronic devices. Much like flipping your light switch at home -- only on a scale 1,000 times smaller than a human hair -- an ASU-led team has now developed the first controllable DNA switch to regulate the flow of electricity within a single, atomic-sized molecule.
