Widespread DNA testing has shed light on the ancestry of millions of Americans. But these services have limitations, and the results can be uncertain, says Joseph Pickrell, a Columbia University computational geneticist.
Adam Sobel, a Columbia University atmospheric scientist, discusses the role climate change played in the flooding that occurred as a result of Tropical Storm Harvey.
Researchers have developed a new method for fabricating a highly efficient selective solar absorber that can harness and convert sunlight to heat for use in energy-related applications, from heating water and generating steam to residential heating.
Climatologists at Columbia University fear that warmer winters will cause the southern pine beetle to infest more and more forests in the northeast in the coming decades.
Over the next few decades, global warming-related rises in winter temperatures could significantly extend the range of the southern pine beetle, one of the world’s most aggressive tree-killing insects, through much of the northern U.S. and southern Canada.
