- 1Secret Cold War bioweapons test exposed millions in Bay Area●The secret Cold War bioweapons test that exposed millions in the Bay Area
A newly detailed account revisits the 1950 Operation Sea-Spray, in which the US Navy sprayed Serratia marcescens bacteria over San Francisco from ships offshore to study how a biological attack might spread. The tests exposed an estimated 800,000 residents to the bacteria without their knowledge, and have since been linked to infections and at least one death. Readers are debating the ethics of secret government experiments on civilians and what accountability, if any, followed.
- 2New Blood Test Distinguishes Bacterial and Viral Infections in Newborns▼Blood Test Differentiates Bacterial and Viral Infections in Newborns
A new blood test can differentiate between bacterial and viral infections in newborns, according to a report by Inside Precision Medicine. The development could help doctors decide when antibiotics are truly needed in infants, where diagnosing infection has long been difficult and often leads to precautionary antibiotic use. The finding is drawing attention in medical and precision diagnostics circles.
- 3University of Kansas wins $5.8 million NIH grant against antibiotic resistance▼University of Kansas Lands $5.8 Million NIH Grant to Fight Antibiotic Resistance
The University of Kansas has been awarded a $5.8 million grant from the National Institutes of Health to support research into combating antibiotic resistance. The funding will back efforts to develop new approaches as drug-resistant bacteria remain a growing global health threat, with the university positioned among institutions receiving major federal support for this work.
- 4Bacteria on coral reef fish gills carry chemosynthesis genes, DNA study finds●DNA reveals chemosynthesis genes in bacteria living on coral reef fish gills
Scientists have found that bacteria living on the gills of coral reef fish carry genes for chemosynthesis, the process of making food from chemicals rather than sunlight. The discovery, reported by Phys.org, suggests gill-dwelling microbes may play a previously overlooked role in reef nutrient cycles and could reshape how researchers understand symbiosis on coral reefs.
- 5Tailored microbiome treatments called the future of veterinary medicine▼Tailored microbiome interventions ‘the future’ of veterinary medicine
Veterinary experts say individualised microbiome interventions are set to become the future of animal health care. Rather than one-size-fits-all treatments, vets would tailor therapies targeting the gut bacteria of individual animals, potentially improving outcomes for digestive, immune and behavioural conditions. The claim comes from VetTimes, which says personalised microbiome approaches could reshape how companion animals and livestock are treated in coming years.

A new finding reports that overlapping genes—genes whose sequences physically overlap on the genome—are subject to different evolutionary pressures depending on the organism. In bacteria, overlapping genes appear to evolve under one set of constraints, while in eukaryotes, or complex life, they follow another. The results suggest that genome architecture shapes how evolution acts on shared genetic material, challenging the assumption that overlapping genes obey universal rules across all living things.
