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.

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.

Although ozone pollution is dropping across many parts of the United States, western Europe and Japan, many people living in those countries still experience numerous days every year in which levels of the lung irritant exceed health-based standards.

Vertical wind shear was still affecting Tropical Cyclone Cebile when NASA's Terra satellite passed over the Southern Pacific Ocean on Feb. 6. Cebile is undergoing a transition into a subtropical cyclone.

Hydrogen is the most abundant element in the universe. And as the race to find energy sources to replace our dwindling fossil fuel supplies continues, hydrogen is likely to play a crucial role.

Hundreds of methane flares observed offshore Western Svalbard in the Arctic are caused by a process that started at the end of the last ice age, according to the study. The methane release happens because the gas is freed from melting hydrates – an icy substance found below the ocean floor, containing methane in a cage of frozen water.

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.

Global ozone has been declining since the 1970s owing to certain man-made chemicals. Since these were banned, parts of the layer have been recovering, particularly at the poles.
