If you flew from the sea towards the land in the north slope of Alaska, you would cross from the water, over a narrow beach, and then to the tundra. From the air, that tundra would look like a landscape of room-sized polygonal shapes. Those shapes are the surface manifestations of the ice in the frozen ground below, a solidified earth known as permafrost.

Emissions from coal-fired power plants in China are fertilizing the North Pacific Ocean with a metal nutrient important for marine life, according to new findings from a USC-led research team.

The researchers believe these metals could change the ocean ecosystem, though it's unclear whether it would be for better or worse.

The presence of insecticides in streams is increasingly a global concern, yet information on safe concentrations for aquatic ecosystems is sometimes sparse. In a new study led by Colorado State University's Janet Miller and researchers at the United States Geological Survey, the team found a common insecticide, fipronil, and related compounds were more toxic to stream communities than previous research has found.

New Rochelle, NY, October 23, 2020--The National Commission on Correctional Health Care (NCCHC) (https://www.ncchc.org/) has awarded the contract to publish Journal of Correctional Health Care (https://home.liebertpub.com/publications/journal-of-correctional-health-care/664/overview) to Mary Ann Liebert, Inc., publishers, (

MIAMI--As the world enters a next wave of the ongoing COVID-19 pandemic, we are aware now more than ever of the importance of a healthy immune system to protect ourselves from disease. This is not only true for humans but corals too, which are in an ongoing battle to ward off deadly diseases spreading on a reef.

Tokyo, Japan - Researchers from Tokyo Metropolitan University have discovered a new mechanism by which clumps of tau protein are created in the brain, killing brain cells and causing Alzheimer's disease. A specific mutation to an enzyme called MARK4 changed the properties of tau, usually an important part of the skeletal structure of cells, making it more likely to aggregate, and more insoluble. Getting to grips with mechanisms like this may lead to breakthrough treatments.

Despite their high accuracy, the majority of the existing instrumental laboratory methods are very laborious and insufficient in terms of quick analysis of the objects under study. A team of scientists of Samara Polytech design cost effective portable analyzers. The recent research results are published in the journal of the American Chemical Society (doi.org/10.1021/acssensors.0c01018).

CHAMPAIGN, Ill. -- A multidisciplinary group that studies the physical and chemical properties of insect wings has demonstrated the ability to reproduce the nanostructures that help cicada wings repel water and prevent bacteria from establishing on the surface. The new technique - which uses commercial nail polish - is economical and straightforward, and the researchers said it will help fabricate future high-tech waterproof materials.

A new discovery about how the body transports dexamethasone, a drug that can increase the survival chances of patients with severe COVID-19, suggests diabetes and other factors may reduce its potentially lifesaving effectiveness. Based on their findings, the researchers say doctors may need to rethink how they dose the drug for certain groups of patients.

Being highly connected to a strong social network has its benefits. Now a new University of Alberta study is showing the same goes for trees, thanks to their underground neighbours.

The study, published in the Journal of Ecology, is the first to show that the growth of adult trees is linked to their participation in fungal networks living in the forest soil.

Boston - A medication frequently used to treat diabetic macular edema, which is the most common cause of blindness in people with diabetes, is less effective when used to treat the condition in Black patients, new study results show. Led by researchers at Boston Medical Center, the study demonstrated that Black patients were significantly less likely than white patients to show short-term visual improvement after both a single injection and a series of three injections with the drug bevacizumab (Avastin), the most common treatment in the U.S. for diabetic macular edema.

Today, the Energy Futures Initiative (EFI) and Stanford University released "An Action Plan for Carbon Capture and Storage in California: Opportunities, Challenges, and Solutions," a report providing policymakers with options for near-term actions to deploy carbon capture and storage (CCS) to meet the state's climate goals.

WASHINGTON (Oct. 22, 2020)--A "safety net" made up of multiple ambitious and interlinked goals is needed to tackle nature's alarming decline, according to an international team of researchers analyzing the new goals for biodiversity being drafted by the UN's Convention on Biological Diversity (CBD).

Poop is full of secrets. For scientists, digging into feces provides insights into animal diets and is particularly useful for understanding nocturnal or rare species. When animals eat, prey DNA travels all the way through animal digestive tracts and comes out again. Poop contains very precise information about the prey species consumed. At the Smithsonian Tropical Research Institute (STRI), a team explored the eating habits of the fringe-lipped bat (Trachops cirrhosus) by examining its poop.

PITTSBURGH, Oct. 22, 2020 - A metabolite produced following consumption of dietary soy may decrease a key risk factor for dementia--with the help of the right bacteria, according to a new discovery led by researchers at the University of Pittsburgh Graduate School of Public Health.
