Supplementing the feed of high-producing dairy cows with the botanical extract capsicum oleoresin, obtained from chili peppers, or a combination of that extract and clove oil resulted in the animals using feed energy more efficiently and emitting less methane from their largest stomach, according to a new study conducted by Penn State researchers.

An often-overlooked water plant that can double its biomass in two days, capture nitrogen from the air — making it a valuable green fertilizer — and be fed to poultry and livestock could serve as life-saving food for humans in the event of a catastrophe or disaster, a new study led by Penn State researchers suggests.

Forests in the coolest, wettest parts of the western Pacific Northwest are likely to see the biggest increases in burn probability, fire size and number of blazes as the climate continues to get warmer and drier, according to new modeling led by an Oregon State University scientist.

Worsening human-induced climate change may have effects beyond the widely reported rising sea levels, higher temperatures, and impacts on food supply and migration – and may also extend to influencing mental distress among high schoolers in the United States.

Several years of drought have left a mark on Morocco.

Shrinking sea ice and shifts in summer food availability have shifted the whales’ migration patterns. 

For much of the last century, the drying effect of aerosols has masked increases in rainfall from greenhouse gases – but as aerosol emissions diminish, average and extreme rains may ramp up.

The Arctic region is experiencing climate change at a much faster rate than the rest of the world.

A team of researchers from the Spatial Epidemiology Lab (SpELL) of the Université libre de Bruxelles (ULB) and the bclimate group of the Vrije Universiteit Brussel (VUB) demonstrate in a new publication the contribution of climate change to the geographical expansion of West Nile virus in Europe. 

Pumpkin toadlets are in trouble. Progressively severe droughts are disrupting the microbiomes of the thumbnail-sized orange frogs, potentially leaving them vulnerable to a deadly fungal disease, according to a new study by an international research team.
