Researchers harness basic and bizarre science to inform human biology and disease
Hundreds of Stanford scientists are studying what makes biology tick, from obscure molecular structures in the malaria parasite to flower-shaped sea squirts.
New findings on coronary artery formation could change how engineers try to regrow them
A new study shows that the process of turning a group of blood vessel cells into an artery actually requires that they stop growing.
New study shines light on how to better engineer fluorescent proteins
Researchers have now captured the ultrafast changes of green fluorescent proteins as they transition between a dark and fluorescent state, using an X-ray laser at …
The skinny on how chickens grow feathers and, perhaps, on how humans grow hair
How do skin cells make regularly spaced hairs in mammals and feathers in birds? Scientists had two opposing theories, but new research at the University …
Researchers discover new mechanism involved in gene silencing
Heterochromatin is a key player in gene regulation. This tightly packed complex of nuclear proteins and DNA is usually found in regions where genes are …
Calcium the conductor: New role found for mineral in bone development
It isn’t news that we need calcium to keep our bones dense and strong. If you don’t get enough calcium in your diet, or if …
Video provides behind-the-scenes look at unusual transport protein
For science geeks out there, this video offers a glimpse of a key protein tasked with transporting vitamin A into cells, and provides a unique …
What matters to Stanford’s Lucy Shapiro, and why
Fasten your seatbelt: Developmental biologist Lucy Shapiro, PhD, is driving, and we're zooming through her achievement-packed 40-year career in less than an hour. Speaking this week …
Epigenetics controls social dominance in African fish
For the few flashy, colorful male African cichlid fish, life is good. They control food, females and territory, and all the other fishies must follow …
