Breakthrough in plant research
The research groups of the Department of Biological and Environmental Sciences of the University of Helsinki and the University of California in San Diego have discovered a gene that is centrally involved in the regulation of carbon dioxide uptake for photosynthesis and water evaporation in plants.   view more (2008-02-28)

Colorado River streamflow history reveals megadrought before 1490
An epic drought during the mid-1100s dwarfs any drought previously documented for a region that includes areas of Arizona, Colorado, New Mexico, Utah and Wyoming.   view more (2007-05-18)

Disease-impact models may rely on incorrect assumptions
Even when we know how a disease affects individual animals, it is challenging to predict what impact it will have on the whole population, and yet predicting how disease affects a population is a primary concern for wildlife conservation and even public health.   view more (2006-04-13)

New climate record shows century-long droughts in eastern North America
A stalagmite in a West Virginia cave has yielded the most detailed geological record to date on climate cycles in eastern North America over the past 7,000 years.   view more (2008-08-19)

AgriLife Research breeder develops drought-tolerant corn
At the end of the day, drought tolerance in corn has to equate to good yields and good quality, not just good looks, said a Texas AgriLife Research scientist.   view more (2008-08-26)

Underlying cause of massive pinyon pine die-off revealed
The high heat that accompanied the recent drought was the underlying cause of death for millions of pinyon pines throughout the Southwest, according to new research.   view more (2005-10-11)

Climate change threatens Amazonian small farmers
A six-year study of Amazonian small farmers and their responses to climate change shows the farmers are vulnerable to natural catastrophes and risky land use practices, say Indiana University Bloomington anthropologists Eduardo Brondizio and Emilio Moran.   view more (2008-03-26)

Western prairies face impending water crisis
The Canadian prairies are facing an unprecedented water crisis due to a combination of climate warming, increase in human activity and historic drought.   view more (2006-04-04)

Scientists use new techniques to narrow down impact of global warming on specific regions
People will soon be able to find out how vulnerable their own local area is to global warming, thanks to new techniques developed by scientists.   view more (2005-11-28)

Research Europe 25 April issue: stories on MEPs and ethics, the neutron drought, Grenoble genomics, research tax and primate facilities.
MEPs warned off FP6 ethics challenge MEPs have been warned that reopening the issue of ethics in Framework 6 will undermine the whole programme. The warning came during three-way negotiations between the Spanish presidency of the EU, MEPs and the Commission last week. The meetings are intended to... view more (2002-04-25)

NASA researchers find satellite data can warn of famine
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.   view more (2007-08-06)

UWE scientists find link between wilting plants and impotence
Researchers studying plant behaviour have discovered similarities between the processes preventing plants from wilting and humans from suffering impotence. Data recently published by the University of the West of England shows the same chemical chain of events is involved in both situations - and... view more (2002-02-21)

New strategy developed to combat West Nile Virus
The spread of West Nile Virus appears to be triggered by a complex interaction of mosquitoes, nesting birds and specific weather patterns, scientists say, which leads to "amplification" of the virus within mosquito populations.   view more (2006-05-05)

Earth, Wind and Volcanoes - Disaster Science
Ash with Altitude "Volcanic ash, ejected into the stratosphere and spread horizontally by the winds, can cause serious damage to aircraft engines and sensors," says Dr Charles Sprinkle of the US National Weather Service. Modern jet engines operate at such high temperatures that volcanic... view more (1999-10-26)

New study links Western wildfires to Atlantic Ocean surface temperatures
Western U.S. wildfires are likely to increase in the coming decades, according to a new tree-ring study led by the University of Comahue in Argentina and involving the University of Colorado at Boulder that links episodic fire outbreaks in the past five centuries with periods of warming sea surface... view more (2006-12-27)

Perennial wheat research looks at options for producers
Perennial wheat? The possibility is being looked at by a Texas Agricultural Experiment Station researcher.   view more (2006-11-29)

Seeing the wood for the trees: research reveals the survival secrets of forest trees
Species extinction or `biodiversity loss` has accelerated at an alarming rate over the past century. Although much of the blame has been laid at the door of human activity, biologists are looking at the factors that influence how species-particularly similar species-co-exist, in their efforts to... view more (2002-05-30)

Many weather factors needed for accurate climate change predictions
Current climate change impact models that consider only one weather variable, such as increasing temperature, sometimes spawn unsubstantiated doomsday predictions, according to researchers at Purdue and North Carolina universities.   view more (2006-11-07)

Disease damages wheat roots, thwarts water uptake
Alterations in irrigation schedules may be needed when wheat streak mosaic infection is suspected in winter wheat crops, according to a Texas Agricultural Experiment Station researcher in Amarillo.   view more (2006-03-02)

Eddies Warm Up The Ocean
Eddies appear in the ocean like in the atmosphere. Atmospheric eddies are short-lived, extremely speedy, and often very hazardous. Oceanic eddies are slower and can be observed only with the use of special equipment, but these eddies gently mixing ocean waters affect the climate in general. For... view more (2002-02-19)

Symbiotic fungi promote invasion into diverse plant communities (Rudgers et al.)
The biodiversity of a community can affect its functional properties, such as its productiveness or its ability to resist invasion by exotic species. Many grass species host fungi in their leaves that can render them more resistant to herbivory, drought, and competition. In a forthcoming issue of... view more (2003-12-10)

How trees manage water in arid environments
The summer of 2006 was the second warmest in the continental United States since records began in 1895, according to the National Climatic Data Center. Moderate to extreme drought conditions were evident in about 40 percent of the country.   view more (2007-01-05)

A link between greenhouse gases and the evolution of C4 grasses
How a changing climate can affect ecosystems is an important and timely question, especially considering the recent global rise in greenhouse gases.   view more (2007-12-21)

Lake Mead Could Be Dry by 2021
There is a 50 percent chance Lake Mead, a key source of water for millions of people in the southwestern United States, will be dry by 2021 if climate changes as expected and future water usage is not curtailed, according to a pair of researchers at Scripps Institution of Oceanography, UC San Diego.   view more (2008-02-13)

Surprising Killer of Southeastern Salt Marshes: Common Sea Snails
Periwinkles, the spiral-shelled snails commonly found along rocky U.S. shorelines, play a primary role in the unprecedented disappearance of salt marsh in the southeastern states, according to new research published in Science.   view more (2005-12-16)
