How would today’s weather patterns look in a warmer, wetter atmosphere – an expected shift portended by climate change?Colorado State University researcher Kristen Rasmussen offers new insight into this question – specifically, how thunderstorms would be different in a warmer world.

HIV, dengue, papillomavirus, herpes and Ebola – these are just some of the many viruses that kill millions of people every year, mostly children in developing countries. While drugs can be used against some viruses, there is currently no broad-spectrum treatment that is effective against several at the same time, in the same way that…

Lakes suffering from harmful algal blooms may not respond to reduced, or even discontinued, artificial nitrogen loading.Many blue-green algae responsible for algal blooms can fix atmospheric nitrogen dissolved in the water, and therefore water stewards should focus their efforts on removing phosphorus from lakes to combat algal blooms.

Carbon capture could help the nation’s coal plants reduce greenhouse gas emissions, yet economic challenges are part of the reason the technology isn’t widely used today. That could change if power plants could turn captured carbon into a usable product.

Human emissions of the potentially harmful trace metal vanadium into Earth’s atmosphere have spiked sharply since the start of the 21st century due in large part to industry’s growing use of heavy oils, tar sands, bitumen and petroleum coke for energy, a new Duke University study finds.

For those of you dreaming of a white Christmas, you can find places that have the best chance of being a winter wonderland according to weather history. The “Historical Probability of a White Christmas” map shows the climatological probability of at least 1 inch of snow being on the ground on December 25 in the…

Aerial drone footage of bowhead whales in Canada’s Arctic has revealed that the large mammals moult and use rocks to rub off dead skin.The footage provides one answer to the mystery of why whales return to Cumberland Sound, Nunavut, every summer, and helps explain some unusual behaviour that has been noted historically by Inuit and…

Human emissions of the potentially harmful trace metal vanadium into Earth’s atmosphere have spiked sharply since the start of the 21st century due in large part to industry’s growing use of heavy oils, tar sands, bitumen and petroleum coke for energy, a new Duke University study finds.“Human emissions of vanadium to the atmosphere now exceed…

Old forests that contain large trees and a diversity of tree sizes and species may offer refuge to some types of birds facing threats in a warming climate, scientists have found.

Food safety practices that Americans take for granted — washing hands with soap, refrigeration, and not cutting raw meat and vegetables on the same surface without disinfection — are not widely practiced in other places around the world, and researchers in Penn State's College of Agricultural Sciences want to change that.
