A molecule produced by gut microbes may help spur heart disease
A leftover from microbes’ meals is linked to early heart disease in people. In mice, it contributed to plaque buildup in the arteries.

You may already have some protection from bird flu, but don’t count on it
Studies suggest that people who had seasonal flus or vaccinations have low antibody levels against H5N1 bird flu.

Climate change may be pushing fungal allergy season earlier
Rising temperatures and changing rainfall patterns may be lengthening fungal allergy season, which starts 3 weeks earlier than it did two decades ago.

Gut microbes may flush ‘forever chemicals’ from the body
Experiments in mice show that some gut bacteria can absorb toxic PFAS chemicals, allowing animals to expel them through feces.

As bird flu evolves, keeping it out of farm flocks is getting harder
New versions of the H5N1 virus are increasingly adept at spreading. Suggestions to either let it rip in poultry or vaccinate the birds could backfire.

Many U.S. babies may lack gut bacteria that train their immune systems
Too little Bifidobacterium, used to digest breast milk, in babies' gut microbiomes can increase their risk of developing allergies and asthma.

Humans have shockingly few ways to treat fungal infections
It's not quite as bad as The Last of Us. But progress has been achingly slow in developing new antifungal vaccines and drugs.

Lining medical stents with hairlike fuzz could fend off infections
Implanted tubes that transport bodily fluids can get gross. A lab prototype suggests a new vibration-based way to keep them clean and prevent infection.

Bird flu in cows shows no signs of adapting to humans — yet
Easy replication in cattle mammary glands means H5N1 bird flu is under no evolutionary pressure to adapt to spread easily in humans.

Fermenting miso in orbit reveals how space can affect a food’s taste
A miso test on the International Space Station shows fermenting food is not only possible in space, it adds nuttier notes to the Japanese condiment.

A new antifungal drug works in a surprising way
Mandimycin, which targets a different essential fungi cell resource than other antifungal drugs, should harm other cell types as collateral — but doesn’t.
