A wearable device measures cortisol in sweat

By drawing in a bit of sweat, a patch developed in the lab of Alberto Salleo can reveal how much cortisol a person is producing. Cortisol is known as the stress hormone but is involved in many important physiological functions.

Bacterial armor could be a new target for antibiotics

Boosting efforts to fight antibiotic resistance, Stanford researchers have found that a thin membrane, thought to be just a shrink wrap around some bacterial cell walls, has structural properties critical for survival.

Coulter grants move healthcare innovation to patients

Every healthcare innovation helping patients today started as no more than a dream and a clever prototype. Now, a new round of ideas is getting a jump start on the path to reality from a grant program intended to accelerate healthcare solutions.

Making intricate images with bacterial communities

A technique for growing sticky films of bacteria into elaborate microscopic images could reveal how potentially dangerous biofilms grow and transmit antibiotic resistance, and could lead to novel biomaterials or synthetic microbial communities.
