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.

Storing carbon dioxide (CO2) deep below the seabed is one way to counteract the increasing concentration of CO2 in the atmosphere. But what happens if such storage sites begin to leak and CO2 escapes through the seafloor? Answers to this question have now been provided by a study dealing with the effects of CO2 emissions on the inhabitants of sandy seabed areas.

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.

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.

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.

Dr Lori Lach, Senior Lecturer at JCU, said the study compared the feeding habits of healthy bees to those infected with the gut parasite Nosema ceranae.

An astonishing number of viruses are circulating around the Earth’s atmosphere – and falling from it – according to new research from scientists in Canada, Spain and the U.S.

Greenland’s vast ice sheet has long been home to Project Iceworm, an abandoned Cold War-era U.S. Army initiative designed to deploy ballistic missiles with nuclear warheads against the Soviet Union. When the project was shuttered in 1967, military planners expected that any materials left on site would be safely frozen in ice and snow in perpetuity.
