Genetically engineered bacteria prevent mosquitoes from transmitting malaria
Malaria kills more than 800,000 people worldwide each year, many are children; researchers have genetically modified a bacterium commonly found in the mosquito’s midgut and found that the parasite that causes malaria in people does not survive in mosquitoes carrying the modified bacterium

Researchers discover a molecule's previously unknown role in fighting off E. coli
Escherichia coli (abbreviated as E. coli) are a large and diverse family of bacteria; most strains of E. coli are harmless, but some can be deadly; E. coli creeps into the food supply through contamination by tiny (usually invisible) amounts of human or animal feces; many people may develop mild symptoms, but some suffer severe complications that can lead to kidney failure and death; researchers discover a molecule’s previously unknown role in fighting off E. coli and other bacterial infections, a discovery that could lead to new ways to protect people from these dangerous microorganisms

Poultry vaccines found to combine into new viruses
Researchers found that two different vaccine viruses — used simultaneously to control the same condition in chickens — have combined to produce new infectious viruses, prompting early response from Australia’s veterinary medicines regulator

Environmental changes lead stressed cows in southern U.S. to produce less milk
Researchers found that the decline in milk production due to climate change will vary across the United States, since there are significant differences in humidity and how much the temperature swings between night and day across the country; for instance, the humidity and hot nights make the Southeast the most unfriendly place in the country for dairy cows

A world free of foot-and-mouth disease within sight
The Departments of Homeland Security and Agriculture have developed a novel vaccine for one of the seven strains of the dreaded foot-and-mouth disease (FMD), paving the way for the development of the others; FMD is one of the most economically devastating diseases in the world for those who raise cows, sheep, pigs, goats, deer, and other cloven-hoofed animals is foot-and-mouth disease

USDA gives GenVec conditional approval for FMD vaccine for cattle
The USDA has issued a conditional license for GenVec’s foot-and-mouth disease (FMD) vaccine for use in cattle; GenVec’s cell line is capable of producing antigens without the use of the highly contagious FMD virus; because the vaccine is produced without using live or killed virus materials, it can be produced cost effectively in the United States and around the world

A record: half of U.S. land area is in various stages of drought
Analysis of the latest drought monitor data revealed that 46.84 percent of the U.S. land area is in various stages of drought, up from 42.8 percent a week ago; previous records were 45.87 percent in drought on 26 August 2003, and 45.64 percent on 10 September 2002; looking only at the forty-eight contiguous states, 55.96 percent of the country’s land area is in moderate drought or worse — also the highest percentage on record

U.K. potential food crisis
Many climate experts believe a slight rise in U.K. temperatures would be beneficial for the farming industry as yields could increase; as temperatures continue to rise, however, farmers would need to use more and more fertilizer on their crops and some livestock would not be as productive; consumers could thus face reduced food choices

Even a limited India-Pakistan nuclear war would substantially reduce global crop yields
Worries about nuclear winter have faded since the end of the cold war, but existing stockpiles of nuclear weapons still hold the potential for devastating global impacts; researchers have found that the climate effects of a hypothetical nuclear war between India and Pakistan would greatly reduce yields of staple crops, even in distant countries

Measuring the uncertainties of pandemic influenza
Researchers have highlighted three factors that could ultimately determine whether an outbreak of influenza becomes a serious epidemic that threatens national health; the research suggests that the numbers in current response plans could be out by a factor of two or more depending on the characteristics of the particular pandemic influenza

Combatting the Measles Threat Means Examining the Reasons for Declining Vaccination Rates
Measles was supposedly eradicated in Canada more than a quarter century ago. But today, measles is surging. The cause of this resurgence is declining vaccination rates.
Social Networks Are Not Effective at Mobilizing Vaccination Uptake
The persuasive power of social networks is immense, but not limitless. Vaccine preferences, based on the COVID experience in the United States, proved quite insensitive to persuasion, even through friendship networks.
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.”
