Increased UV From Ozone Depletion Sterilizes Trees

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.

Here is the Perfect Spot for a Birds' Inner Compass

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.

Sick Bees Eat Healthier

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.

Tiny Pollutants Intensify Storms in the Amazon

Ultrafine aerosol particles found in polluted urban air can contribute to more intense storms in the Amazon rainforest, with potential knock-on effects for weather and climate patterns in the region and beyond, researchers have warned.

Carleton University Partners with Cuso International to Help Farmers in Peru

Carleton University students are consulting with small-scale farmers in Peru as part of a partnership with the international development organization Cuso International.

Students in the Bachelor of Global and International Studies program (BGInS) at Carleton University are gaining hands-on experience while improving food security in Peru thanks to an innovative partnership with Cuso International. The partnership, which began in January, is the first of what Cuso International hopes will be a new wave of e-volunteering opportunities for students at Carleton and across Canada.

New research reveals patterns of US and global ozone pollution

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.

NASA Finds Wind Shear Still Affecting Tropical Cyclone Cebile

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: Fuel of the Future?

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.

Sea Floor Uplift After Last Ice Age Causes Methane Release in the Arctic Today

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.

Viruses - Lots of Them - Are Falling From the Sky

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.
