The courts have played a central role in climate change policy, starting with a landmark Supreme Court case that led to the mandatory regulation of greenhouse gases in the United States. How do the courts address climate cases today? Who wins, who loses and what kinds of strategies make a difference in the courtroom?

Researchers at the George Washington University (GW) have published a study in Nature Climate Change that for the first time analyzes all U.S climate change lawsuits over a 26-year period.

“This first-of-a-kind study outlines the types of climate change lawsuits that are more likely to win or lose, and why,” said lead author Sabrina McCormick, Ph.D., MA, an Associate Professor of Environmental and Occupational Health at GW’s Milken Institute School of Public Health (Milken Institute SPH). “Efforts to affect U.S. climate change policy should consider current trends in the courtroom.”

The life-threatening bacteria called MRSA can cripple a hospital since it spreads quickly and is resistant to treatment. But scientists report that they are now making advances in a new technique that avoids antibiotics. Instead, they are using light to activate oxygen, which then wipes out antibiotic-resistant bacteria. The method also could be used to treat other microbial infections, and possibly even cancer.

The researchers are presenting their results today at the 256th National Meeting & Exposition of the American Chemical Society (ACS).

Clinical facilities currently have few alternatives when trying to rid their patients of MRSA (methicillin-resistant Staphylococcus aureus). The Veterans Health Care System, for example, hires infection prevention staff to track hand hygiene. Going even further, one recent study found that disinfecting every patient admitted to an acute-care setting cut the rate of bloodstream infections in half. However, this procedure isn’t feasible at most hospitals.

Dartmouth scientists have created a more sustainable feed for aquaculture by using a marine microalga co-product as a feed ingredient. The study is the first of its kind to evaluate replacing fishmeal with a co-product in feed designed specifically for Nile tilapia. The results are published in the open access journal, PLOS ONE.

Aquaculture is the world’s fastest growing food sector, surpassing the global capture fisheries production in 2014. It provides more than 50 percent of the food supply to humans; however, it poses several environmental concerns. Aquaculture feed (aquafeeds) draws on 70 percent of the world’s fishmeal and fish oil, which is obtained from small, ocean-caught fish such as anchovies, sardines, herring, menhaden, and mackerel¬, that are essential to the lower end of the marine food chain. Analysts project that by 2040, the demand for fishmeal and fish oil will exceed supply. Aquafeeds also draw on large amounts of soy and corn from industrial farms, which pose other environmental concerns due to the use of fertilizers and potential runoff into rivers, lakes and coastal waters. In addition, aquafeeds may trigger nutrient pollution in aquaculture effluent, as fish are unable to fully digest soy and corn, which are major feed ingredients.

To address the environmental sustainability concerns regarding aquafeed, a Dartmouth team has been developing sustainable feeds for Nile tilapia, which examine the effectiveness of replacing fishmeal and fish oil with different types of marine microalgae. Marine microalgae are excellent sources of essential amino acids, minerals, vitamins, and omega-3 fatty acids, and can therefore, meet the nutrient requirements of fish. Omega-3 fatty acids are important for maintaining fish health; they also have neurological, cardiovascular and anti-cancer benefits to humans.

Herpes Viruses And Alzheimer’s: A Possible Link : Shots — Health News Two herpes viruses that cause skin rashes in toddlers may accelerate Alzheimer’s disease when they infect brain cells. The finding suggests antiviral drugs might help protect the brain.

A global plastic waste crisis is building, with major implications for health and the environment. Under its so-called “National Sword” policy, China has sharply reduced imports of foreign scrap materials. As a result, piles of plastic waste are building up in ports and recycling facilities across the United States.

In response, support is growing nationally and worldwide for banning or restricting single-use consumer plastics, such as straws and grocery bags. These efforts are also spurred by chilling findings about how micro-plastics travel through oceans and waterways and up the food chain.

A new form of electronics manufacturing which embeds silicon nanowires into flexible surfaces could lead to radical new forms of bendable electronics, scientists say.

In a new paper published today in the journal Microsystems and Nanoengineering, engineers from the University of Glasgow describe how they have for the first time been able to affordably ‘print’ high-mobility semiconductor nanowires onto flexible surfaces to develop high-performance ultra-thin electronic layers.

Those surfaces, which can be bent, flexed and twisted, could lay the foundations for a wide range of applications including video screens, improved health monitoring devices, implantable devices and synthetic skin for prosthetics.
