Cloud Seeding Measurement

澳门开奖结果2023开奖记录 atmospheric scientist Katja Friedrich and her colleagues have, for the first time, accurately measured the volume of snow produced through cloud seeding, a process that turns lightweight water vapor into heavier droplets to produce precipitation. Last January, they used radar to measure three seeding events in Idaho and found that, combined, they produced a total of about 282 Olympic-sized swimming pools worth of water. The research can help scientists determine whether cloud-seeding efforts are useful in the long run to produce rain or snow in areas that need more water.

Forest Recovery, Post-Beetles

Warmer and drier conditions in U.S. forests have caused an influx of bark beetle outbreaks. In Colorado alone, spruce beetles have affected more than 1.8 million acres of Engelmann spruce trees since 2000. CU research, published in the journal Ecology, reveals that beetle outbreaks aren鈥檛 completely detrimental to forests, however. 鈥淲e found that 86% of the stands of trees that we surveyed are currently on a trajectory for recovery,鈥� said lead author Robert Andrus (PhDGeog鈥�19). Their findings can help determine more targeted responses to forest disturbances.

SickStick Wins Top Prize

In the virtual finale of a 150-company contest, the 鈥淪ickStick鈥� by Darwin Biosciences won CU鈥檚 New Venture Challenge, gaining $55,000 in prize money and investments. The developing SickStick technology is a saliva-based diagnostic that will determine illness before symptoms occur. The company hopes to use the over-the-counter device to test for COVID-19 later this year.
