A new study shows that some of Yellowstone National Park’s forests may now be at a climate tipping point, and could be replaced by grassland by the middle of this century.

The new process converts infrared energy into visible light, allowing innocuous radiation to penetrate living tissue and other materials without the damage caused by high-intensity light exposure.

Vijay Modi, a professor in the Department of Mechanical Engineering at Columbia University and an Earth Institute faculty member, and his research group are studying how to decarbonize heating.

Armed with advanced genomic tools, Columbia scientists have uncovered an ingenious mechanism that underlies the brain’s ability to distinguish different smells.

A team from Columbia’s Earth Institute, led by senior research scientist Cynthia Rosenzweig, is helping to research and design adaptation strategies to help save the world’s second largest barrier reef.

The scientists identified a group of genes in roundworms that control the onset of puberty and induce sex differences in neural structures, raising questions of whether differences in male and female behavior are hardwired in our brains.
