The red tide that is choking Florida’s southwest coast is causing symptoms including coughs, headaches and shortness of breath, local doctors say.

Today we have an interview with Sci-Hub creator, Alexandra Elbakyan who is committed to the free flow of scientific knowledge and is challenging the unfair journal system which charges outrageous fees to view scientific publications.
Hiding scientific knowledge behind paywalls
Around 70% of scientific publications are hidden behind paywalls, restricting access to knowledge and progress. We believe that this is unfair and that putting profit before the health of others is morally repugnant, and this is part of why we support the concept of Open Science, particularly the work of Alexandra Elbakyan.

Wealthy Singapore is hyper-connected and on a drive to digitise government records and essential services, including medical records which public hospitals and clinics can share via a centralised database.
But authorities have put the brakes on these plans while they investigate the cyberattack. A former judge will head a committee looking into the incident.
While the city state has some of the most advanced military weaponry in the region, the government says it fends off thousands of cyberattacks every day and has long warned of breaches by actors as varied as high-school students in their basements to nation states.

“The big problem is that hospitals don’t buy new devices, and they keep using really dangerous ones ad infinitum — until they just stop working,” Corman said.
Corman wants these old, unsecured devices gone from hospitals. The fear is that, beyond freezing systems or hijacking medical records as they did during WannaCry, hackers could also actively manipulate medical equipment to harm patients by, say, administering a lethal dose of medication via an infusion pump. While newer devices aren’t ironclad, they are typically built with more robust security features. So Corman and others are urging health-care providers to scrap old, or “legacy,” equipment and replace it with newer models.
To nudge health-care providers to trade up, he’s put forth an idea for an incentive program akin to “Cash for Clunkers,” the 2009 federal auto-rebate plan that aimed to run gas-guzzling cars off the road. Under that program, which was formally called the Car Allowance Rebate System, people received cash in exchange for turning in fuel-inefficient vehicles, which they could then put toward new, more efficient ones. (The program fizzled after a few months, when it depleted its allotted budget.) Similarly, in this version, health-care providers would be compensated for junking old equipment, and could use the rebates toward the purchase of new devices. Corman said he hasn’t fully worked out the economics, but he believes device makers might be willing to subsidize the program in part, since it would help them move inventory.

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.
