Treating oil spills with chemical dispersants may do more damage than good
Treating oil spills at sea with chemical dispersants is detrimental to European fisheries. Post-spill chemical dispersants may reduce problems for surface animals, but the increased contamination under the water reduces the ability for fish and other organisms to cope with subsequent environmental challenges.

Researchers highlight problem of legacy mercury in the environment
Researchers have published evidence that significant reductions in mercury emissions will be necessary just to stabilize current levels of the toxic element in the environment. So much mercury persists in surface reservoirs (soil, air, and water) from past pollution, going back thousands of years, that it will continue to persist in the ocean and accumulate in fish for decades to centuries, they report.

Increasing food production from existing farmland
A policy known as sustainable intensification could help meet the challenges of increasing demands for food from a growing global population. The goal of sustainable intensification is to increase food production from existing farmland. Sustainable intensification would minimize the pressure on the environment in a world in which land, water, and energy are in short supply.

Improving crop resilience, yields in a world of extreme weather
Farmers in the United States witnessed record-breaking extremes in temperature and drought during the last two summers, causing worldwide increases in the costs of food, feed and fiber. Indeed, many climate scientists caution that extreme weather events resulting from climate change is the new normal for farmers in North America and elsewhere, requiring novel agricultural strategies to prevent crop losses. UC Riverside-led research team develops new chemical for improving crop drought tolerance.

FDA warns about vulnerability of medical devices to hacking
The Food and Drug Administration (FDA) has warned manufactures of medical devices implanted into the human body, such as pacemakers and insulin pumps, to step up their cybersecurity efforts. The agency said it has discovered “cybersecurity vulnerabilities and incidents that could directly impact medical devices or hospital network operations.”

FDA-approved medications may stop deadly ebola
Ebola infections carry fatality rates of up to 90 percent. It strikes both humans and other primates, and there are fears it could be used as a biological weapon. There is no cure. New research suggests that a class of drugs that includes treatments for breast cancer and infertility appears able to inhibit the deadly, incurable Ebola virus.

The future of Colorado River flows
The Colorado River provides water for more than thirty million people, including those in the fast-growing cities of Las Vegas, Phoenix, and Los Angeles. Increasing demand for that water combined with reduced flow and the looming threat of climate change have prompted concern about how to manage the basin’s water in coming decades.

DHS wants to upgrade BioWatch, but admits the system addresses a receding threat
The BioWatch program has cost more than $1 billion so far, and DHS wants billions more for upgrading it. The system is designed to detect large-scale bioterror attacks, but DHS, in its revised assessment of bioterror threats to the United States, said that rather than a massive release of germs in an American city – the kind of attack BioWatch sensors were aimed to detect – the more likely bioterror attacks are small-scale releases of anthrax or other pathogens. Such small-scale attack would likely not be picked up by BioWatch. Lawmakers want to know whether investing billions more in the system is worthwhile.

Factors influencing spinach E. coli contamination before harvest
Researchers have identified a variety of factors that influence the likelihood of E. coli contamination of spinach on farms prior to harvest. They found that E. coli contamination of spinach on farms in Colorado and Texas was 172 times more likely if the produce field was within ten miles of a poultry farm, and sixty-four times more likely if irrigated by pond water.

New microfluidic chip useful in counterterrorism, water and food safety
A new process for making a three-dimensional microstructure that can be used in the analysis of cells could prove useful in counterterrorism measures and in water and food safety concerns. Researchers developed a new microfabrication technique to develop three-dimensional microfluidic devices in polymers. Microfluidics deals with the performance, control, and treatment of fluids that are constrained in some fashion.

Vaccine Integrity Project Says New FDA Rules on COVID-19 Vaccines Show Lack of Consensus, Clarity
Sidestepping both the FDA’s own Vaccines and Related Biological Products Advisory Committee and the CDC’s Advisory Committee on Immunization Practices (ACIP), two Trump-appointed FDA leaders penned an opinion piece in the New England Journal of Medicine to announce new, more restrictive, COVID-19 vaccine recommendations. Critics say that not seeking broad input into the new policy, which would help FDA to understand its implications, feasibility, and the potential for unintended consequences, amounts to policy by proclamation.
Are We Ready for a ‘DeepSeek for Bioweapons’?
Anthropic’s Claude 4 is a warning sign: AI that can help build bioweapons is coming, and could be widely available soon. Steven Adler writes that we need to be prepared for the consequences: “like a freely downloadable ‘DeepSeek for bioweapons,’ available across the internet, loadable to the computer of any amateur scientist who wishes to cause mass harm. With Anthropic’s Claude Opus 4 having finally triggered this level of safety risk, the clock is now ticking.”
“Tulsi Gabbard as US Intelligence Chief Would Undermine Efforts Against the Spread of Chemical and Biological Weapons”: Expert
The Senate, along party lines, last week confirmed Tulsi Gabbard as Director of National intelligence. One expert on biological and chemical weapons says that Gabbard’s “longstanding history of parroting Russian propaganda talking points, unfounded claims about Syria’s use of chemical weapons, and conspiracy theories all in efforts to undermine the quality of the community she now leads” make her confirmation a “national security malpractice.”
