Low-cost imaging system detects natural gas leaks in real time
Researchers have developed an infrared imaging system that could one day offer low-cost, real-time detection of methane gas leaks in pipelines and at oil and gas facilities. Leaks of methane, the primary component of natural gas, can be costly and dangerous while also contributing to climate change as a greenhouse gas. Infrared device enables reliable monitoring under a range of environmental conditions.

Dual-use sciene, technological innovation
Scientific research can change our lives for the better, but it also presents risks – either through deliberate misuse or accident. Think about studying deadly pathogens; that’s how we can learn how to successfully ward them off, but it can be a safety issue too, as when CDC workers were exposed to anthrax in 2014 after an incomplete laboratory procedure left spores of the bacterium alive. Making decisions about the security implications of science and technology can be complicated. That’s why scientists and policymakers need clarity on the dual-use distinction to help consider our options.

Malaria superbugs pose threat to global malaria control
A lineage of multidrug resistant P. falciparum malaria superbugs has widely spread and is now established in parts of Thailand, Laos and Cambodia, causing high treatment failure rates for the main falciparum malaria medicines, artemisinin combination therapies (ACTs). The emergence and spread of artemisinin drug resistant P falciparum lineage represents a serious threat to global malaria control and eradication efforts.

Global partnership to prevent epidemics with new vaccines launched
A global coalition to create new vaccines for emerging infectious diseases, designed to help give the world an insurance policy against epidemics, launches today at the World Economic Forum in Davos, Switzerland.
With an initial investment of $460 million from the governments of Germany, Japan, and Norway, plus the Bill & Melinda Gates Foundation and the Wellcome Trust, CEPI - the Coalition for Epidemic Preparedness Innovations will seek to outsmart epidemics by developing safe and effective vaccines against known infectious disease threats that could be deployed rapidly to contain outbreaks, before they become global health emergencies.

Millions of tons of food could be saved with better logistics
Each year, nearly a quarter of a million tons of food is discarded in industry and retail in Sweden – unnecessarily. Researchers want to do something about it, giving companies in the food supply chain specific tools that can reduce both food waste and the environmental impact of food transport.

Cocktail of bacteria-killing viruses prevents cholera infection in animal models
Oral administration of viruses that specifically target cholera bacteria prevents infection and cholera-like symptoms in animal model experiments. The findings are the first to demonstrate the potential efficacy of bacteria-killing viruses—known as bacteriophages, or phages—as an orally administered preventive therapy against an acute gastrointestinal bacterial disease.

Stopping human-made droughts and floods before they start
Alberta’s rivers are a main source of water for irrigated agriculture in Canada’s Prairie provinces. But climate change and increased human interference mean that the flow of these headwaters is under threat. This could have major implications for Canadian gross domestic product, and even global food security.

What caused the Flint water crisis
Flint, Michigan, continues to grapple with the public health crisis that unfolded as lead levels in its tap water spiked to alarming levels. Now the scientists who helped uncover the crisis have tested galvanized iron pipes extracted from the “ground zero” house. They confirm that the lead that had accumulated on the interior surface of the pipes was the most likely source of the lead contamination.

Do Americans want to buy ‘smart’ guns?
“Smart gun” refers to firearms that include some sort of safety device designed to make sure that the gun can be fired only by an authorized user. These safety devices include fingerprint recognition, wearable “tags” that a gun can recognize and other similar features. Smart guns are not yet widely available on the market. But would Americans actually buy smart guns? We need more studies with larger, nationally representative samples and more detailed questions about smart guns. However, my study sheds light on how subgroups of Americans feel about the issue. Not all gun owners or nonowners feel the same way about smart guns. Support is not evenly divided by political party. American attitudes toward smart guns are complex and do not necessarily follow the patterns we might expect.

Engineering mosquitoes to fight Zika
The United States Agency for International Development (USAID) has awarded a $1 million grant to Michigan State University to fight the Zika virus in Mexico. The funding will be used by Zhiyong Xi, MSU associate professor of microbiology and molecular genetics, to build a mosquito factory in Yucatan, Mexico. The facility will be modeled after a similar facility in Guangzhou, China which Xi leads in partnership with Sun Yat-sen University.

Bioterrorism poses catastrophic threat to U.S. agriculture
The agriculture sector in the U.S. is a $1 trillion business and employs approximately 9.2 percent of American workers. In 2012, domestic animal agriculture – livestock and poultry production – generated approximately 1.8 million jobs, $346 billion in total economic output and $60 billion in household income. Experts are calling better understanding of the threats to agriculture posed by biological agents which can inflict catastrophic consequences on the U.S. population and economy.

World still “grossly underprepared” for infectious disease outbreaks
The world remains “grossly underprepared” for outbreaks of infectious disease, which are likely to become more frequent in the coming decades, warn a team of international experts. They reviewed reports on the recent Ebola virus outbreak in West Africa and say better preparedness and a faster, more coordinated response could have prevented most of the 11,000 deaths directly attributed to Ebola and also the broader economic, social, and health crises that ensued. “We will not be ready for the next outbreak without deeper and more comprehensive change,” they conclude.

U.S. harvests to suffer from climate change
Some of the most important crops risk substantial damage from rising temperatures. To better assess how climate change caused by human greenhouse gas emissions will likely impact wheat, maize and soybean, an international team of scientists now ran an unprecedentedly comprehensive set of computer simulations of U.S. crop yields. The simulations were shown to reproduce the observed strong reduction in past crop yields induced by high temperatures, thereby confirming that they capture one main mechanism for future projections.

Drug-resistant “nightmare bacteria” can diversify, spread
A family of highly drug-resistant and potentially deadly bacteria may be spreading more widely — and more stealthily — than previously thought. CRE, which tend to spread in hospitals and long-term care facilities, cause an estimated 9,300 infections and 600 deaths in the United States each year, according to the DCD.

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.”
