Climate change might help pests resist corn’s genetic weapon

Climate change might be great news for pests looking to munch on genetically modified crops, researchers propose. In particular, researchers analyzed 21 years of data from Maryland cornfields and suggest that rising temperatures might help corn earworms (Helicoverpa zea) develop resistance faster to a widespread genetically built-in crop protection. Some commercial varieties of corn have […]

Mars has nighttime snow storms

Nighttime may be snow-time on Mars. Low evening temperatures could cool clouds and trigger turbulent winds that fuel fast-falling snowstorms on the Red Planet, new simulations suggest. This process, reported August 21 in Nature Geoscience, may account for surprising observations of snowfall by one of NASA’s Martian landers. “Clouds and snowfall have emerged in recent […]
