*University-Vikings partnership helps children lead healthier lives*
Even if you’re not a football fan, you’ve probably noticed the Minnesota Vikings in the news a lot, whether it’s in regard to the 2011 season or their push for a new stadium.
What often goes unnoticed is the team’s record of community engagement and financial benevolence. Over the years the Vikings have given millions to the local community. (more…)
Washington, DC — Scientists have long debated about the impact on global climate of water evaporated from vegetation. New research from Carnegie’s Global Ecology department concludes that evaporated water helps cool the earth as a whole, not just the local area of evaporation, demonstrating that evaporation of water from trees and lakes could have a cooling effect on the entire atmosphere. These findings, published September 14 in Environmental Research Letters, have major implications for land-use decision making.
Evaporative cooling is the process by which a local area is cooled by the energy used in the evaporation process, energy that would have otherwise heated the area’s surface. It is well known that the paving over of urban areas and the clearing of forests can contribute to local warming by decreasing local evaporative cooling, but it was not understood whether this decreased evaporation would also contribute to global warming (more…)
*Water significant limiting factor in growing crops like switchgrass*
Energy researchers and environmental advocates are excited about the prospect of gaining more efficient large-scale biofuel production by using large grasses like miscanthus or switchgrass rather than corn.
They have investigated yields, land use, economics and more, but one key factor of agriculture has been overlooked: water.
“While we are looking for solutions for energy through bioenergy crops, dependence on water gets ignored, and water can be a significant limiting factor,” said Praveen Kumar, an environmental engineer and atmospheric scientist at the University of Illinois at Urbana-Champaign. (more…)
Skewed skulls may have helped early whales find direction of sounds in water
Skewed skulls may have helped early whales find the direction of sounds in water and are not solely, as previously thought, a later adaptation related to echolocation. (more…)
WASHINGTON – The U.S. Environmental Protection Agency (EPA) is providing almost $10 million in grants to 37 states, territories and tribes to help protect swimmers and beachgoers at America’s beaches. The grants will help local authorities monitor beach water quality and notify the public of conditions that may be unsafe for swimming. The grants have enabled states and territories to more than double the number of beaches they monitor since 2003. This continues EPA’s efforts to help beach managers provide consistent public health protection and up-to-date information about local beach conditions. (more…)
Right now, it looks a little like one of those plastic containers you might fill with gasoline when your car has run dry. But Scott Gallager is not headed to the nearest Mobil station. The Woods Hole Oceanographic Institution (WHOI) biologist has other, grander plans for his revolutionary Swimming Behavioral Spectrophotometer (SBS), which employs one-celled protozoa to detect toxins in water sources.
Not only is he working on streamlining the boxy-looking contraption—eventually even evolving it into a computer chip—but he sees it as a tool to potentially “monitor all the drinking water in the world.
“It has a unique utility.” (more…)
COLUMBIA, Mo. – Parents are often amazed at how fast their child grows and develops. New research at the University of Missouri has determined that the ability to quantify – even things that are hard to quantify, such as liquid – may develop much sooner than most parents realize.
University of Missouri researcher Kristy vanMarle, an assistant professor in the Department of Psychological Sciences in the College of Arts and Science, has determined that contrary to what previous studies have shown, infants are able to quantify non-cohesive substances – like sand, water, or even Cheerios – as early as 10 months. As long as the difference between the two substances is large enough, vanMarle has found that infants will choose the larger amount, especially when it comes to food. (more…)
The National Science Foundation has signed a five-year, $34.5-million agreement with the University of Wisconsin-Madison to operate a unique telescope–a cubic kilometer in volume–buried in the Antarctic ice sheet between 1,400 meters and 2,400 meters deep.
The collaborative agreement covers the cost of operating the IceCube Neutrino Observatory, located in the ice under the U.S. Amundsen-Scott South Pole Station. The observatory records the rare collisions of neutrinos, elusive sub-atomic particles, with the atomic nuclei of the water frozen into ice. Neutrinos come from the sun, cosmic rays interacting with the Earth’s atmosphere, and dramatic astronomical sources such as exploding stars in the Milky Way and other distant galaxies. Trillions of neutrinos stream through the human body at any given moment, but they rarely interact with regular matter, and researchers want to know more about them and where they come from. (more…)
