Crop breeding is not keeping pace with climate change
Crop yields will fall within the next decade due to climate change unless immediate action is taken to speed up the introduction of new and improved varieties, experts have warned. The researchers focused on maize in Africa but the underlying processes affect crops across the tropics.

Zika threatens world's blood supply: Experts
Blood safety researchers say it is highly likely that the mosquito-borne Zika virus can be transmitted through blood transfusions and are calling for an evidence-based approach to protecting the blood supply from the threat of Zika virus.

Predicting contagiousness to help limit the spread of disease
Imagine the workplace during flu season. Some people get sick and display clear symptoms — a warning sign to coworkers to avoid contact and for that individual to stay home. Others are infected, but never or only belatedly exhibit the tell-tale signs of sickness, meaning they can infect coworkers without knowing it. If healthcare professionals had the ability to test in advance whether a person is likely to spread a disease following infection, they could recommend specific measures to treat the person or limit exposure and perhaps keep an outbreak from growing into an epidemic or pandemic. DARPA’s new Prometheus program is setting out to develop that predictive capability.

Testing NYC subway biodefenses
Researchers took to the New York City subway system 9-13 May to study how a surrogate for a biological agent, such as anthrax, might disperse throughout the nation’s largest rapid transit system as a result of a terrorist attack or an accidental release. The study is part of a five-year DHS project called Underground Transport Restoration (UTR) and was conducted in accordance with the National Environmental Policy Act.

Electronic anti-theft systems pose a threat to cardiac device patients
Researchers say that electronic anti-theft systems still post a threat to cardiac device patients. Experts say that even though reported events are rare, prolonged exposure to electronic anti-theft systems, also called electronic article surveillance (EAS) systems, can cause pacing therapy to drop beats or in the worst case leave pacemaker dependent patients with no heartbeat, and cause ICDs to deliver inappropriate shocks.

Floridians uncomfortable with use of genetically modified mosquitoes to limit spread of disease
A small survey of residents of a Florida Keys neighborhood where officials hope to release genetically modified mosquitos to potentially reduce the threat of mosquito-borne illnesses such as Zika finds a lack of support for the control method.

New proposal seeks to focus on the fix for lead poisoning
The crisis of lead-contaminated drinking water in Flint, Michigan, continues to make headlines — but it is just the most prominent example of an “ongoing and needless tragedy of childhood lead poisoning,” says a leading expert on childhood lead poisoning prevention. The “debacle” in Flint should spur urgently needed but long-delayed action to address the continuing crisis of lead poisoning in the United States and around the world.

Zika virus expert: Tourists should “think twice” about going to Disney World
A leading public health expert has warned tourists to “think twice” about visiting parts of the United States, including Walt Disney World in Florida, because of the future threat of the Zika virus in the country. Pregnant women and couples looking to conceive should be particularly wary of going on holiday to southern states such as Florida, Texas, and Louisiana, he said.

Predicting the spread of the Zika virus
Countries that are well connected to Brazil have been at particularly high risk of importation of the Zika virus, according to researchers. However, subtropical and tropical countries with a history of dengue and other mosquito-borne diseases have the greatest risk of the virus spreading once it arrives in the country.

Pennsylvania superbug infection could mean "the end of the road" for antibiotics: Researchers
Researchers have, for the first time, found a person in the United States carrying a bacteria resistant to antibiotics of last resort. Top U.S. public health officials say this is alarming, and could mean “the end of the road” for antibiotics. Researchers say that the discovery “heralds the emergence of a truly pan-drug resistant bacteria.”

New paper filter removes viruses from water
More than 748 million people around the world lack access to safe drinking water and basic sanitation. Water-borne infections are among the global causes for mortality, especially in children under age of five, and viruses are among the most notorious water-borne infectious microorganisms. They can be both extremely resistant to disinfection and difficult to remove by filtration due to their small size. Scientists have developed a simple paper sheet which can improve the quality of life for millions of people by removing resistant viruses from water.

Rapid detection of E. coli in water
Tragedies like the E. coli outbreak in Ontario’s Walkerton in May 2000 could be averted today with a new invention by researchers at York University that can detect the deadly contaminant in drinking water early. Anew technology has cut down the time taken to detect E. coli from a few days to just a couple of hours.

Biodefense Panel welcomes key provision in defense authorization bill
In October 2015, the Blue Ribbon Study Panel on Biodefense found that insufficient federal coordination on strategy, budgeting, and policy; inadequate collaboration with other levels of government and the private sector; and lagging innovation in areas like biosurveillance and medical countermeasure development make the United States vulnerable to biological attacks and infectious disease outbreaks. The Panel welcomed the passing by the House of the National Defense Authorization Act, H.R. 4909, which includes a provision addressing one of the Panel’s most important recommendations.

A tool to help public health decisions on Zika virus to be cost-effective
A new study presents a cost-effectiveness tool that can help guide decisions regarding resource allocation to fund interventions targeted at curtailing the ongoing Zika virus outbreak. Analyses using the tool suggest that proposed funds to combat Zika in the United States and other countries would be cost-effective, based on quantification of the serious health conditions associated with Zika infection.

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.”
