Shifting Ozone Hole Exposed South America to More Ultraviolet Light in 2009 PDF Print E-mail
Wednesday, 01 September 2010 23:07
The ozone layer, which protects humans, plants, and animals from potentially damaging ultraviolet (UV) light from the Sun, develops a hole above Antarctica in September that typically lasts until early December. However, in November 2009, that hole shifted its position, leaving the southern tip of South America exposed to UV light at levels much greater than normal.

Wonder of the Natural World: Key to Christmas Island's Red Crab Migration Discovered PDF Print E-mail
Wednesday, 01 September 2010 23:03
One of the most spectacular migrations on Earth is that of the Christmas Island red crab (Gecarcoidea natalis). Acknowledged as one of the wonders of the natural world, every year millions of the crabs simultaneously embark on a five-kilometre breeding migration. Now, scientists have discovered the key to their remarkable athletic feat.

Aquatic invaders can topple plant and fish populations in Northeast PDF Print E-mail
Monday, 30 August 2010 23:13

The introduction of species like "Frankenfish" or "Rock Snot" into Pennsylvania waters doesn't sound pretty, and it's not. These are just two of the more colorful nicknames for aquatic invaders, but the innocent-sounding ones -- such as parrot feather or water chestnut -- also have the capacity to spell doom for some local ponds and streams.

Commercial trap for wasps, hornets and yellowjackets 'baited' with new technology PDF Print E-mail
Monday, 30 August 2010 23:09

Forget the ants marching one by one--yellowjackets are the real party-crashers when it comes to spoiling picnics, outdoor barbeques and other summer fun where cold beverages and meat are present.

Fortunately, a new trap is available that lures these stinging, sugar-sipping pests to their doom, thanks to attractants developed by U.S. Department of Agriculture (USDA) scientists and commercialized by Sterling International, Inc., of Spokane, Wash. The scientists work for USDA's chief intramural scientific research agency, the Agricultural Research Service (ARS).

Nanobiotechnology-Manipulated Light Particles Used to Accelerate Algae Growth PDF Print E-mail
Wednesday, 25 August 2010 16:37
Scientists and engineers seek to meet three goals in the production of biofuels from non-edible sources such as microalgae: efficiency, economical production and ecological sustainability. Syracuse University's Radhakrishna Sureshkumar, professor and chair of biomedical and chemical engineering in the L.C. Smith College of Engineering and Computer Science, and SU chemical engineering Ph.D. student Satvik Wani have uncovered a process that is a promising step toward accomplishing these three goals.

Is the Ice in the Arctic Ocean Getting Thinner? PDF Print E-mail
Tuesday, 24 August 2010 03:05
The extent of the sea ice in the Arctic will reach its annual minimum in September. Forecasts indicate that it will not be as low as in 2007, the year of the smallest area covered by sea ice since satellites started recording such data. Nevertheless, sea ice physicists at the Alfred Wegener Institute are concerned about the long-term equilibrium in the Arctic Ocean.

Scientists Map and Confirm Origin of Large, Underwater Hydrocarbon Plume in Gulf PDF Print E-mail
Tuesday, 24 August 2010 03:02
Scientists at the Woods Hole Oceanographic Institution (WHOI) have detected a plume of hydrocarbons that is at least 22 miles long and more than 3,000 feet below the surface of the Gulf of Mexico, a residue of the BP Deepwater Horizon oil spill.

Marine Animals Suggest Evidence for a Trans-Antarctic Seaway PDF Print E-mail
Wednesday, 01 September 2010 23:05
A tiny marine filter-feeder, that anchors itself to the sea bed, offers new clues to scientists studying the stability of the West Antarctic Ice Sheet -- a region that is thought to be vulnerable to collapse.

As part of a study for the Census of Antarctic Marine Life (CAML), scientists from British Antarctic Survey (BAS) analysed sea-bed colonies of bryozoans from coastal and deep sea regions around the continent and from further afield.

Impact Hypothesis Loses Its Sparkle: Shock-Synthesized Diamonds Said to Prove Catastrophic Impact Killed Off N. American Megafauna Can't Be Found PDF Print E-mail
Wednesday, 01 September 2010 23:01
About 12,900 years ago, a sudden cold snap interrupted the gradual warming that had followed the last Ice Age. The cold lasted for the 1,300-year interval known as the Younger Dryas (YD) before the climate began to warm again.

'Swindon Honeybee' could save Britain's bees PDF Print E-mail
Monday, 30 August 2010 23:11

Honey bee numbers have been declining almost everywhere due to a pesticide-resistant mite called Varroa. Now a beekeeper in Britain claims to have discovered a strain of bee that destroys the parasite through grooming.

Ron Hoskins, a 79-year-old retired heating engineer from Swindon, has spent the last 18 years searching for a breed of honey bee that is resistant to the Varroa mite, and has now bred a strain in which the bees remove the mites by grooming one another.

Controlling insects in stored grain PDF Print E-mail
Monday, 30 August 2010 23:07

Aeration -- blowing ambient air through grain storage bins -- has been used for decades to maintain the quality of grain by keeping it cool, as well as to manage stored insect pests. But few recent studies have examined whether it's better to direct air from above or below as a means of using temperatures of 60 degrees Fahrenheit or below to control insects.

Sea Level to Rise Even With Aggressive Geo-Engineering and Greenhouse Gas Control, Study Finds PDF Print E-mail
Saturday, 28 August 2010 02:01
New findings by international research group of scientists from England, China and Denmark just published suggest that sea level will likely be 30-70 centimetres higher by 2100 than at the start of the century even if all but the most aggressive geo-engineering schemes are undertaken to mitigate the effects of global warming and greenhouse gas emissions are stringently controlled.

Tropically Speaking, NASA Investigates Precipitation Shapes, Sizes for Severity PDF Print E-mail
Saturday, 28 August 2010 01:56
Rain drops are fat and snowflakes are fluffy, but why does it matter in terms of predicting severe storms?

We've all seen fat rain drops, skinny rain drops, round hailstones, fluffy snowflakes and even ice needles. This summer, NASA researchers are going to get a look at just how much these shapes influence severe storm weather.

Deep Plumes of Oil Could Cause Dead Zones in the Gulf PDF Print E-mail
Tuesday, 24 August 2010 03:04
A new simulation of oil and methane leaked into the Gulf of Mexico suggests that deep hypoxic zones or "dead zones" could form near the source of the pollution. The research investigates five scenarios of oil and methane plumes at different depths and incorporates an estimated rate of flow from the Deepwater Horizon spill, which released oil and methane gas into the Gulf from April to mid July of this year.
