Australian scientists are much closer to developing a screening test for the early detection of Alzheimer's disease. They identified blood-based biological markers that are associated with the build up of a toxic protein in the brain which occurs years before symptoms appear and irreversible brain damage has occurred.

Do frogs live underground? The answer is yes, some amphibians, such as salamanders and frogs have been often reported to dwell in subterranean habitats, some of them completely adjusted to the life in darkness, and others just spending a phase of their lifecycle in an underground shelter. Up until 2010, however, no one suspected that the Mediterranean anuran frog Rana iberica - commonly kno

WHAT: NIH-supported scientists used lab-grown human lung cells to study the cells' response to infection by a novel human coronavirus (called nCoV) and compiled information about which genes are significantly disrupted in early and late stages of infection. The information about host response to nCoV allowed the researchers to predict drugs that might be used to inhibit either the virus

Staring at a small patch of sky for more than 50 hours with the ultra-sensitive Karl G. Jansky Very Large Array (VLA), astronomers have for the first time identified discrete sources that account for nearly all the radio waves coming from distant galaxies. They found that about 63 percent of the background radio emission comes from galaxies with gorging black holes at their cores and the remaining

When it comes to deciding which light bulb to buy, a label touting the product's environmental benefit may actually discourage politically conservative shoppers.

North America isn't known as a hotspot for crop plant diversity, yet a new inventory has uncovered nearly 4,600 wild relatives of crop plants in the United States, including close relatives of globally important food crops such as sunflower, bean, sweet potato, and strawberry.

Nesting green sea turtles are benefiting from marine protected areas by using habitats found within their boundaries, according to a U.S. Geological Survey study that is the first to track the federally protected turtles in Dry Tortugas National Park.

U.S. residents who believe in the scientific consensus on global warming are more likely to support government action to curb emissions, regardless of whether they are Republican or Democrat, according to a study led by a Michigan State University sociologist.

At the end of a long day, it can be more convenient to order your groceries online while sitting on the living room couch instead of making a late-night run to the store. New research shows it's also much more environmentally friendly to leave the car parked and opt for groceries delivered to your doorstep.

As temperatures warm, plants release gases that help form clouds and cool the atmosphere, according to research from IIASA and the University of Helsinki.
