Social media sites often present users with social exclusion information that may actually inhibit intelligent thought, according to the co-author of a University at Buffalo study that takes a critical look not just at Facebook and other similar platforms, but at the peculiarities of the systems on which these sites operate.

Plants in the Arctic are growing taller because of climate change, according to research from a global scientific collaboration.

A University of Adelaide-led team of researchers has found a link between sudden cardiac death (when the heart suddenly stops beating) and a common heart condition known as mitral valve prolapse that affects around 12 in every 1000 people worldwide.

The Sherpa people of the Himalayas have long been recognized for their unique ability to excel physically in the thin air of higher altitudes. But new research from UBC’s Okanagan campus, published last week in the Journal of Physiology, now suggests that their specially adapted muscles give them up to twice the resistance to muscle fatigue of lowlanders.

One of the major sources of uncertainty about the future climate is whether ecosystems will continue to take up carbon dioxide or release it to the atmosphere. University of Montana researchers and co-authors confronted this problem using atmospheric measurements and satellite observations to test model simulations in a recent study published on Sept. 5 in Nature Communications.

With bee populations in decline, a new study offers hope for a relatively simple mechanism to promote bee health and well-being: providing bees access to sunflowers.

An innovation in liquid metal chemistry could help one tenth of the planet’s population get access to clean drinking water at very low cost following breakthrough research.

Mountaintop removal, a coal-mining technique used in much of Central Appalachia, is an extreme form of surface mining, that excavates ridges as deep as 600 feet — twice the length of a football field — and buries adjacent valleys and streams in bedrock and coal residue. This mining activity has long been known to have negative impacts on water quality downstream.

A new NASA-led study helps answer decades-old questions about the role of smoke and human-caused air pollution on clouds and rainfall. Looking specifically at deep convective clouds -- tall clouds like thunderclouds, formed by warm air rising -- the study shows that smoky air makes it harder for these clouds to grow. Pollution, on the other hand, energizes their growth, but only if the pollution isn't heavy. Extreme pollution is likely to shut down cloud growth.

It seems “hangry” isn’t just a made-up term.

University of Guelph researchers have revealed that the sudden drop in glucose we experience when we are hungry can impact our mood.
