Social- versus food-related brain cells
Researchers at Stanford demonstrated that direct stimulation of fewer than two dozen neurons linked to social interaction was enough to suppress a mouse’s drive to feed itself.
How bacteria harness fluid currents
Figuring out how bacteria bring in nutrients could point to ways of killing them without poison. More generally, this research could also reveal how small organisms cooperate by generating networks of flow patterns.
Mystery of a simple marine animal
Watching the movement of every cell in an adult animal all at once, the Prakash lab discovered ultra-fast cellular contractions. This research suggests a new role for cellular contractions in tissue cohesion.
Concussion study in high school football
Three Bay Area high school football teams have been outfitted with mouthguards that measure head motion. Stanford scientists hope to use the data to better understand what causes concussions.
Swimming in polygons to avoid stronger light
A bioengineering lab has found that Euglena, a microscopic organism that has been studied for hundreds of years, swims in precise polygons when exposed to increased light intensity.
Head, neck position affects concussion risk
The way the head and neck are positioned during a head-on impact may significantly affect the risk of concussion, but tensed up neck muscles seem to offer far less protection, Stanford researchers found.
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.
Teams are taking part in a Stanford competition to train virtual musculoskeletal models with a prosthetic leg to walk and run.
Karl Deisseroth wins Kyoto Prize
The award, which includes a gift of 100 million yen (about $913,000), recognizes the neuroscientist for pioneering and advancing a technology for studying brain circuits.
Protein mimic eases breathing
The material could be used to synthesize a film that coats the inner surface of lungs, possibly leading to better, cheaper treatments for acute lung injury in humans.
