The Arctic is comparatively clean. Due to the prevailing worldwide sea and air currents, the Arctic area is also the fallout region for long-range transport pollutants, and in some places the concentrations exceed the levels of densely populated urban areas. An example of this is the phenomenon of Arctic haze, which is commonly blamed on…

Omega 3 fatty acids are fats commonly found in marine and plant oils. The health effects of n-3 fatty acids supplementation are controversial. They are considered essential fatty acids, meaning that they cannot be synthesized by the human body but are vital for normal metabolism. A new study by the University of Oxford has shown…

It is one of the oldest beliefs throughout the history of mankind; that with age, comes greater wisdom. For most cases this is true, particularly in learning a skill such as playing an instrument or constructing a house. But does knowing how to perform a skill more efficiently really make that person smarter, or have…

On Mars’s poles there are ice caps of ice and dust with multiple layers that can tell us much about climate variations on Mars. Researchers from the Niels Bohr Institute have related the layers in the ice cap on Mars’s north pole to variations in solar insolation on Mars, thus established the first dated climate…

Climate change may have a profound effect on the world’s ability to produce wheat — one of its staple crops — and adaptation efforts must take into account both the positive and negative effects of climate shifts, say wheat experts.

What you eat tells a lot about one’s lifestyle. This is especially true in the animal kingdom and interestingly important for extinct species we know little about. Recent finds of two large compsognathid Sinocalliopteryx gigas in China’s Liaoning province by a paleontology team from the University of Alberta have drawn conclusions that this species was…

The amount of time it takes to recharge lithium-ion batteries has been a major impediment to consumer acceptance of electric vehicles. But a host of companies and researchers are working intensively to develop a battery that can recharge in 10 minutes and power a car for hundreds of miles. If stopping for gas took five…

Recycling has long been the low-hanging fruit of sustainability in both neighborhoods and offices. More municipalities and office buildings have recycling programs and for the consumer, pitching those cereal boxes, bottles and cans are even easier than before. Single-stream or “commingled” recycling programs make it even easier for us: the days of separate and clunky…

Hurricane Isaac was a slow-moving tropical cyclone that caused severe damage along the northern Gulf Coast of the United States in late-August 2012. Isaac reached hurricane strength the morning of August 28. The storm made its first U.S. landfall at 6:45 p.m. CDT that evening (2345 UTC), near the mouth of the Mississippi River. As…

Scientists say this year’s record declines in Arctic sea ice extent and volume are powerful evidence that the giant cap of ice at the top of the planet is on a trajectory to largely disappear in summer within a decade or two, with profound global consequences. As the northern summer draws to a close, two…
