Electron beam reduces virus-related health risk in lettuce, spinach
Current health-care costs in the United States associated with foodborne viruses are estimated at about $6 billion; scientists show that electron-beam irradiation can reduce the health risks in iceberg lettuce and spinach, but note that electron-beams are not meant to be used as a “stand-alone” or “clean-up” technology

Cold plasma reduces harmful bacteria on raw chicken
Recent high-profile outbreaks of foodborne illness have involved contaminated fresh produce, but the most common source of harmful bacteria in food is uncooked poultry and other meat products; studies have shown that plasma could successfully reduce pathogens on the surface of fruits and vegetables without cooking them, and scientists demonstrates that plasma can be an effective method for killing pathogens on uncooked poultry

Understanding – and averting -- drug resistance in bacteria
Bacterial resistance to antibiotics is growing exponentially, contributing to an estimated 99,000 deaths from hospital-associated infections in the U.S. annually; one reason that this is happening is that drug resistant proteins are transporting “good” antibiotics, or inhibitors, out of the cells, leaving them to mutate

Research collaboration to fight Campylobacter jejuni
Campylobacter, primarily C. jejuni, is the third leading cause of death from foodborne infections in the world; in the United States alone, it affects nearly 2.4 million people, causes an estimated 58,000 illnesses and 200 deaths, and costs companies millions of dollars in recall losses each year

Invaders wreak havoc on U.S. ecosystems
In the decade since the 9/11 attacks, DHS’ focus on combatting terrorism has left some of its core agencies ill-equipped to perform its other missions, namely the Customs and Border Protection’s (CBP) ability to prevent invasive plants and insects from entering the United States and wreaking havoc on crops

Protein study to help in superbug battle
Scientists have shed light on the way superbugs such as MRSA are able to become resistant to antibiotics; the researchers have done it by mapping the complex molecular structure of an enzyme found in many bacteria

Scientists offer new information for fighting flu
Influenza is the world’s leading cause of morbidity and mortality; seasonal viruses affect up to 15 percent of the human population and cause severe illness in five million people a year; in the United States, financial losses caused by seasonal influenza are estimated to exceed $87 billion annually

Stealthy leprosy pathogen evades immune response
Leprosy, one of the world’s oldest known diseases, is a chronic infectious disease that affects the skin, the peripheral nerves, the upper respiratory tract, and the eyes and can lead to disfigurement of the hands, face, and feet; scientists’ findings point to new treatment pathways for leprosy – and other infectious diseases

How new viruses evolve and become deadly
Scientists demonstrate how a new virus evolves, which sheds light on how easy it can be for diseases to gain dangerous mutations; this demonstration follows recent news that scientists in the United States and the Netherlands produced a deadly version of bird flu

Scientists urge accelerated flu research
The discovery by scientists that H5N1 virus could potentially be transmitted between mammals has led to fears both of misuse and of accidental release – and to requests of two leading science publication to edit and redact portions of two articles in which the findings of the research are reported; a leading specialist argues that H5N1 viruses circulating in nature may already pose a threat because influenza viruses constantly mutate and can cause pandemics

Farmers urge Congress to reject antibiotic restrictions in animals
Pending bills H.R. 965 (House) and S. 1211 (Senate) would remove specific antibiotics and classes of antibiotics from animal feed; the purpose is to make sure that bacteria these antibiotics are aimed to combat do not become drug-resistant, thus endangering human health and lives; farmers and ranchers say the bills go too far

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.”
