Meta has launched an AI agent called Muse, designed to assist users but requiring them to share extensive personal information to function effectively. Coverage describes Muse's appearance as cartoonish and unusual, likened to a children's character crossed with a microbe.
A long-form explainer details the biology of chemotaxis, the process by which a single E. coli cell detects attractive chemicals and decides whether to swim forward or tumble to change direction. The piece walks through receptor proteins, membrane signaling, chemical modifications that act as memory, and the flagellar motor that drives movement, framing the bacterium as a sophisticated molecular computer rather than a simple organism.
Sierra Nevada Cheese Company has stopped making and shipping all Graziers Raw Milk Cheese products as health officials investigate an E. coli outbreak linked to the cheeses. Thirteen people have fallen ill, with eight requiring hospitalization, prompting a nationwide recall of the affected products.
The FSIS's century-old 'poke and sniff' meat inspection system, born from the 1906 Federal Meat Inspection Act, proved unable to detect microscopic pathogens like E. coli as beef consumption soared. The 1993 Jack in the Box E. coli outbreak, which sickened over 700 people and killed four children, forced federal regulators to speed up adoption of a science-based safety approach originally developed by NASA for feeding astronauts.
A frozen blueberry product sold at Walmart has been added to an expanding recall linked to an E. coli outbreak the CDC has been tracking since May. Health officials report a rising number of hospitalizations tied to contaminated frozen blueberries.
Researchers modified the tethered Ribo-T ribosome system in E. coli by appending open reading frames for GFP, DFR and HiBiT directly onto the 3′ end of 16S rRNA, creating 'Ribo-TM' constructs. Gel electrophoresis and RT-PCR confirmed the fused mRNA-rRNA molecules were intact and correctly assembled inside functioning ribosomes, and growth assays with mutant ribosomal subunits helped verify that translation activity depended on a functional ribosome.
Scientists engineered synthetic protein assemblies from the bottom up that can package and transport RNA molecules into human cells, using standard molecular cloning and transfection techniques in HEK293T cell lines. They validated the approach with a split-luciferase reporter system to confirm successful RNA delivery and functional expression inside cells.
The FDA has tracked over 12,800 illnesses linked to foodborne outbreaks in 2026, dwarfing the 895 cases recorded in all of 2025. Recent outbreaks include salmonella tied to jalapeños, eggs, and dog food, plus a combined E. coli and salmonella outbreak from alfalfa sprouts, following what experts call an unprecedented cyclospora outbreak from tainted lettuce that ranks as the largest since the 1990s.
The CDC has confirmed a growing multistate outbreak tied to alfalfa sprouts, with dozens of illnesses reported across 15 states and four people hospitalized. Michigan and Wisconsin have recorded the highest case counts, and the update comes just days after a recall of multiple alfalfa sprout products linked to the contamination.
