The 3,000-kilometer-long Transantarctic Mountains are a dominant feature of the Antarctic continent, yet up to now scientists have been unable to adequately explain how they formed. In a new study, geologists report that the mountains appear to be the remnant edge of a gigantic high plateau that began stretching and thinning some 105 million years ago, leaving the peaks curving along the edge of a great plain.

Researchers exploring a remote terrain in Arctic Canada have made discoveries that may rock the world of Canadian geology.

Geologists from the University of Alberta have found that portions of Canada collided a minimum of 500 million years earlier than previously thought. Their research, published in the American journal Geology, is offering new insight into how the different continental fragments of North America assembled billions of years ago.

Ice loss from glaciers and ice caps is expected to cause more global sea rise during this century than the massive Greenland and Antarctic ice sheets, according to a new University of Colorado at Boulder study.

A NASA researcher has developed a new method to anticipate food shortages brought on by drought. Molly Brown of NASA’s Goddard Space Flight Center in Greenbelt, Md., and her colleagues created a model using data from satellite remote sensing of crop growth and food prices.

Ethanol is 'oversold' a new report says.

The future of biofuels is not in corn, says a new report released today by Food & Water Watch. The corn ethanol refinery industry, the beneficiary of new renewable fuel targets in the proposed energy legislation as well as proposed loan guarantee subsidies in the 2007 Farm Bill, will not significantly offset U.S. fossil fuel consumption without unacceptable environmental and economic consequences.

Primetime crime drama meets reality in forensic research taking place at the Midwest Forensics Resource Center at Iowa State University.

Ames Laboratory scientists are using the new Direct Analysis in Real Time mass spectrometry interface, which has made a guest appearance on the popular crime show "CSI: New York," to build a library of ink mass spectra using samples from the US Secret Service. The mass spectra library will help identify inks on fraudulent documents and other crime evidence.

You have a greater possibility of losing weight if you eat a diet that is high in foods like lentils that release energy slowly once they have been consumed, rather than one that is high in foods that rapidly release sugar into the blood stream such as white bread, a Cochrane Systematic Review has concluded.

Scientists say that using data from the Mars Express mission and numerical models they can determine how the orbit of Mars around the Sun accounts for the origin and perennial occurrence of water ice at the Martian South Pole.

Many earthquakes in the deep ocean are much smaller in magnitude than expected. Geophysicists from the Woods Hole Oceanographic Institution have found new evidence that the fragmented structure of seafloor faults, along with previously unrecognized volcanic activity, may be dampening the effects of these quakes.

A team of led by Norwich BioScience Institutes Professor Nick Harberd have discovered how plants evolved the ability to adapt to changes in climate and environment.

Plants adapt their growth, including key steps in their life cycle such as germination and flowering, to take advantage of environmental conditions. They can also repress growth when their environment is not favorable. This involves many complex signalling pathways which are integrated by the plant growth hormone gibberellin.
