Seeking secrets of worm’s regenerative power
No one knows exactly how flatworms can rebuild their entire bodies from the tiniest sliver. Now, bioengineers and materials scientists are building new tools to study the worms’ awesome regenerative powers.
Targeting cancer, sparing healthy cells
Stanford researchers have developed synthetic proteins that can rewire cancer cells in a lab dish by co-opting critical disease-associated pathways.
Possible role of deep brain structure in concussion
Through a combination of biometric tracking, simulated modeling and medical imaging, Stanford researchers have detailed how hits to the side of the head may cause concussion.
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.
