Some calves are inherently optimistic or pessimistic, just as humans are, a new University of British Columbia study has found.

Recognizing these individual personality differences is important to ensure animals are treated well, says professor Marina von Keyserlingk, who led the research team from UBC’s animal welfare program in the faculty of land and food systems.

Researchers from North Carolina State University have developed a new technique that uses existing technologies to detect potential airborne radiological materials in hours instead of days.

The remote forests of Africa’s Congo Basin have long been a blind spot for scientists working to understand how Earth’s natural cycles respond to the environmentally unique characteristics of different regions.

Renewable energy solutions are often hindered by the inconsistencies of power produced by wind, water and sunlight and the continuously fluctuating demand for energy. New research by Mark Z. Jacobson, a professor of civil and environmental engineering at Stanford University, and colleagues at the University of California, Berkeley, and Aalborg University in Denmark finds several solutions to making clean, renewable energy reliable enough to power at least 139 countries.

Stanford geophysicists have developed a detailed map of the stresses that act in the Earth throughout the Permian Basin in West Texas and southeastern New Mexico, highlighting areas of the oil-rich region that could be at greater risk for future earthquakes induced by production operations.

The human microbiome – the trillions of tiny bacteria that live in and on our bodies – is emerging as an increasingly important player in health and wellness. But, our co-existence with these organisms is complex, and scientists are learning that even minor changes in this relationship can lead to big problems with our health. 

Exposure to air pollution, even imagining exposure to air pollution, may lead to unethical behavior, according to findings published in Psychological Science, a journal of the Association for Psychological Science. A combination of archival and experimental studies indicates that exposure to air pollution, either physically or mentally, is linked with unethical behavior such as crime and cheating. The experimental findings suggest that this association may be due, at least in part, to increased anxiety.

Pine trees become temporarily sterile when exposed to ultraviolet radiation as intense as some scientists believe the Earth experienced 252 million years ago during the planet’s largest mass extinction, lending support to the theory that ozone depletion contributed to the crisis.

Migratory birds use a magnetic compass in their eye for navigation. Its basic sensory mechanisms have long remained elusive, but now researchers reveal exactly where in the eye, the birds’ control center for navigation is situated.
