Vitamin C affects whether genes are switched on or off inside mouse stem cells, suggesting that it could may play a fundamental role in helping to guide normal development in mice, humans and other animals, a team led by UC San Francisco researchers has discovered.

A new study shows that the first meal influences how the lizards disperse from their birthplaces, how they grow, and whether they survive. For young lizards born into this unpredictable world, their very first meal can be a major life changer. Neonates face a great challenge in acquiring their first meal, as is the case in many species that develop skills through learning to capture live prey.

Call it a bird’s eye view of migration. Scientists are taking a fresh look at animal movement with a big data approach that combines GPS tracking data with satellite weather and terrain information.

The new Environmental-Data Automated Track Annotation (Env-DATA) system, featured in the journal Movement Ecology, can handle millions of data points and serve a hundred scientists simultaneously, said co-founder Dr. Roland Kays, a zoologist with North Carolina State University and the North Carolina Museum of Natural Sciences.
