Did last ice age affect breast feeding in Native Americans?

Dr. Leslea Hlusko, Associate Professor of Integrative Biology, and her lab have interesting new findings. "The critical role that breast feeding plays in infant survival may have led, during the last ice age, to a common genetic mutation in East Asians and Native Americans that also, surprisingly, affects the shape of their teeth."

Increased UV from ozone depletion sterilizes trees

“Paleontologists have come up with various kill scenarios for mass extinctions, but plant life may not be affected by dying suddenly as much as through interrupting one part of the life cycle, such as reproduction, over a long period of time, causing the population to dwindle and potentially disappear,” said co-author Cindy Looy, a UC Berkeley associate professor of Integrative Biology.

California’s Dry Regions are Hotspots of Plant Diversity

The first “big data” analysis of California’s native plants, using digitized information from more than 22 herbaria and botanical gardens around the state, provides some surprises about one of the most thoroughly studied and unique areas in the country.

For one, the state’s arid regions, including deserts such as Death Valley, are hotspots for originating new plant species and providing refuges for older plants that have disappeared elsewhere.

Fourteen HHMI Professors Take On Important Challenges in Science Education

The Howard Hughes Medical Institute (HHMI) announced today that 14 leading scientists have been named HHMI professors, an award that recognizes excellence in research and education and empowers recipients to explore new approaches to important challenges in science education. HHMI is awarding 10 individual grants of $1 million each and two grants for collaborative projects that will receive a total of $1.5 million each over five years.
