Climatic impacts of megapolitan expansion
Arizona’s Sun Corridor is the most rapidly-growing megapolitan area in the United States. Nestled in a semi-arid environment, it is composed of four metropolitan areas: Phoenix, Tucson, Prescott, and Nogales. With a population projection expected to exceed 9 million people by 2040; a first study of its kind, attempting to quantify the impact of rapidly expanding megapolitan areas on regional climate, showed that local maximum summertime warming resulting from projected expansion of the urban Sun Corridor could approach 4 degrees Celsius

Water sustainability flows through complex human-nature interactions
The fate of water in China mirrors problems across the world: water is fouled, pushed far from its natural origins, squandered, and exploited; China’s crisis is daunting, though not unique: two-thirds of China’s 669 cities have water shortages, more than 40 percent of its rivers are severely polluted, 80 percent of its lakes suffer from eutrophication — an over abundance of nutrients — and about 300 million rural residents lack access to safe drinking water

Immediate, in-the-field identification of hazardous materials
Soldiers in war zones, and law enforcement and first responders on the scene will soon have the ability to collect and immediately analyze trace amounts of potentially dangerous chemical, explosive, or biological agents with the help of a surface swabbing device developed and prototyped by a Maine-based technology company with the help of the University of Maine researchers

USDA’s proposed chicken safety inspection policy could mean trouble for consumers
The federal government has come up with a new proposal to examine chickens for contaminates and diseases, and the proposal has some people concerned and others outright scared; the proposal would reduce the number USDA food safety inspectors at poultry plants from four to one – and rely on plant’s employees to do safety inspections instead

Improved disaster resilience is imperative for U.S: report
A new report from the National Academies says that it is essential for the United States to bolster resilience to natural and human-caused disasters, and that this will require complementary federal policies and locally driven actions that center on a national vision – a culture of resilience; improving resilience should be seen as a long-term process, but it can be coordinated around measurable short-term goals that will allow communities better to prepare and plan for, withstand, recover from, and adapt to adverse events

Extreme summer heat events, global warming linked: research
Since the late 1980s researches have been asserting that global warming would reach a point in the coming decades when its connection to extreme events would become more apparent; while some warming should coincide with a noticeable boost in extreme events, the natural variability in climate and weather can be so large as to disguise the trend; to distinguish the trend from natural variability, NASA researchers turned to statistics; the researchers did not focus on the causes of temperature change, analyzing instead surface temperature data

Canadian company offers the first treatment to neutralize red mud
Red mud is the most significant waste product of the traditional Bayer process for aluminum production; the industry produces more than 100 million tons of red mud a year, of which less than 5 percent is be reused; the rest is stored in ponds and reservoirs, posing serious environmental and economic risk; on 4 October 2010, for example, a flood of toxic red mud devastated Hungary after a retaining dyke ruptured, causing an ecological disaster; Canadian company Orbite Aluminae offers a technology to tackle the aluminum industry’s most serious problem

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.”
