Using biological means to detoxify large, contaminated sites is receiving high praise as an alternative to incineration or landfill methods

A pesticide used extensively all over the world is receiving attention these days more for methods being used to clean it up than for its use as chemical to control insects and mites.

Endosulfan, classified as an organochlorine (the same family as DDT), is registered for use as a pesticide on 60 U.S. crops. Its residues have been found i

The spectacular aurora borealis displays that light up the northern nights could be powered by a gigantic “slinky” effect in Earth’s magnetic field lines, according to research performed at the University of Minnesota. Earth’s magnetic field resemble a slinky in that when “wiggled,” it undulates in waves that travel down the field lines at speeds up to 25 million miles per hour. These waves can pass energy to electrons, accelerating them along the magnetic field lines toward Earth. When the

Mysterious patterns arise through simple feedback mechanisms and self-organization

Perfect circles of stones cover the ground in parts of Alaska and the Norwegian islands of Spitsbergen. Elsewhere in the far north, stones form other striking patterns on the ground: polygons, stripes, islands, and labyrinths. No, pranksters are not at work in these remote areas, nor are aliens, elves, or any other outside forces moving the stones around. According to scientists who have studied the phe

GAIKER is a participant in a project at a multinational level which is financed by the European Union Competitive and Sustainable Growth Project. The project is to develop innovative technology which will have two aspects or stages: firstly the separation and recovery of components capable of being reused and, subsequently, the recycling of materials used in electronic printed circuit boards (from telephones, T.V.’s, and so on). The great quantity of small parts, different components, solder and oth

Wheat growers turn to aerial imagery to overcome economic, environmental challenges

Today’s wheat growers face many economic and environmental challenges, but arguably their greatest challenge is the efficient use of fertilizer.

Growers need to apply nitrogen-based fertilizer in sufficient quantities to achieve the highest possible crop yields without over-applying – a situation that could lead to serious environmental effects. In wheat, a critical factor comes down to

A doctor gets a better view inside a patient by probing the body with CAT and MRI scanning equipment. Now, NASA meteorologists have done a kind of “full-body scan” of an evolving thunderstorm in the tropics, using advanced radar equipment to provide a remarkable picture of the storm’s anatomy. The observations are expected to help double-check satellite rainfall measurements, improve computer models of storms, and make the skies safer for airplanes to navigate.

NASA-funded scientists have recently learned that cloud-to-ground lightning frequently strikes the ground in two or more places and that the chances of being struck are about 45 percent higher than what people commonly assume.

Recently, William C. Valine and E. Philip Krider in the Institute of Atmospheric Physics at the University of Arizona, co-authors of the study, took to the field using video and other technology to study lightning, which is one of the biggest weather-related killers i

Findings detailed in Jan. 16 issue of Nature; greenhouse gases implicated

A study by University of Massachusetts Amherst geoscientist Robert DeConto posits an alternative theory regarding why Antarctica suddenly became glaciated 34 million years ago. The study challenges previous thinking about why the ice sheet formed and holds ramifications for the next several hundred years as greenhouse gases continue to rise. DeConto, who collaborated with David Pollard of Pennsylvania State Univ

Two University of York graduates have found and preserved the giant tusk of the largest elephant fossil of its type ever to be found in the Middle East.

The tusk, two-and-a-half metres long and thought to be between six and eight million years old, was discovered by Dr Mark Beech, who finished his PhD at York recently and is now senior resident archaeologist for the Abu Dhabi Islands Archaeological Survey (ADIAS).

Mark discovered the tusk in Abu Dhabi’s Western Region last October

Climate change had little to do with the demise of the dinosaurs, but the last million years before their extinction had a complex pattern of warming and cooling events that are important to our understanding of the end of their reign, according to geologists.

“The terrestrial paleoclimate record near the K-T is historically contradictory and poorly resolved,” says Dr. Peter Wilf, assistant professor of geosciences at Penn State. “In contrast, the resolution of K-T marine climates that has

A dramatic increase in deformed frogs and other amphibians is being caused by a range of environmental factors, all of which ultimately can be linked to human impacts on habitat, but the primary cause of many of the deformities is an epidemic of a key parasite.

These findings are the results of eight years of research by scientists around the world, and are presented in the February issue of Scientific American by researchers from Oregon State University and the University of Wisconsin.

A rare dolphin species known for assisting fishermen by driving fish into their nets may soon disappear from the great Asian river for which the animals are named. According to a recent scientific survey by the Wildlife Conservation Society (WCS) and its partners, the Irrawaddy dolphin may vanish from the Ayeyarwady River (formerly Irrawaddy) without efforts to protect these aquatic mammals from human activities along the river.

A research team with members from WCS, WDCS (the Whale and Dol

Innovative tests trigger clean up efforts at popular California beach

A UC Irvine-led study has proved instrumental for significantly improving the quality of beach water at a popular California tourist destination. The same study also provides the blueprint for assisting similar beachside communities with an innovative approach for pinpointing the causes of water pollution.

The research was headed by UCI environmental engineer Stanley Grant and USC microbiologist Jed Fuhrman

With fewer than 300 northern right whales remaining, the seriously endangered species may face yet another obstacle to recovery. The right whale is regularly exposed to the neurotoxins responsible for paralytic shellfish poisoning (PSP) through feeding on contaminated zooplankton. These toxins could affect respiratory capabilities, feeding behavior, and ultimately the reproduction condition of the whale population.

In the current issue of the journal Harmful Algae, a team of scientists, led

Unless the pace of global warming is abated, polar bears could disappear within 100 years, says a University of Alberta expert in Arctic ecosystems.

While it has been known for some time that the polar bear is in trouble, new research shows that Arctic ice–the polar bear’s primary habitat–is melting much faster than scientists had believed, says U of A biologist Dr. Andrew Derocher.

“The climate predictions coming out are showing massive changes in sea-ice distribution,” sa

Scientists at Long Ashton Research Station have identified a gene with a pivotal role in regulating seed germination. According to an article published in the January issue of BBSRC business, the Arabidopsis COMATOSE (CTS) gene, is vital for breaking seed dormancy. It is also analogous to the human X-ALD gene, which featured in the 1992 film “Lorenzo’s oil”. Treatment of cts mutants with a plant version of Lorenzo’s oil cures their inability to germinate.

The researchers were inves
