Decisions, decisions: Feedback influences decision making
Every day we are faced with a multitude of choices, but the majority of these fall into two categories: descriptive choice (based on what we are told) and experiential choice (based on our own personal experience).   view more (2008-11-13)

Lichens function as indicators of nitrogen pollution in forests
Scientists have found lichens can give insight into nitrogen air pollution effects on Sierra Nevada and San Bernardino mountain ecosystems, and protecting them provides safeguards for less sensitive species.   view more (2008-10-07)

Field of the future -- ecological experiment simulates conditions in 2100
A new experiment to find out how British plant ecosystems may be affected by future changes to climate and biodiversity is underway at Imperial College London.   view more (2008-09-29)

University of Virginia Study Reveals Promising Method for Reducing MRSA Infections in Hospital Intensive Care Units
Doctors at the University of Virginia Health System have significantly reduced MRSA infections among surgical intensive care patients by using antibiotic cycling, a method of rotating drugs at regular intervals.    view more (2008-09-05)

Study: Delaying evolution of drug resistance in malaria parasite possible
There's no magic bullet for wiping out malaria, but a new study offers strong support for a method that effectively delays the evolution of drug resistance in malaria parasites, a University of Florida researcher says.   view more (2008-09-05)

Evolving designer ecosystem sheds light on unintended consequences
Amidst the semi-arid stretches of Phoenix, a visitor might blink twice at the sight of a sailboat cutting across the horizon. Tempe Town Lake, on the northern edge of Arizona State University (ASU), is just one of a multitude of lakes, small ponds, canals and dams combining flood control, water... view more (2008-09-04)

A virtuous cycle: Safety in numbers for riders
It seems paradoxical but the more people ride bicycles on our city streets, the less likely they are to be injured in traffic accidents.   view more (2008-09-03)

Getting to the Root of the Matter
Like most things that exist underground, plant roots are out-of-sight and easily forgotten, but while flowers, leaves, and other aboveground plant parts are more familiar, plant roots are equally deserving of our appreciation. Beneath every towering tree, tasty crop, and dazzling ornamental lies a... view more (2008-08-20)

UNC trial: oral contraceptives may ease suffering of women with severe PMS
A new clinical trial at the University of North Carolina at Chapel Hill using a popular low-dose contraceptive could uncover a more effective treatment for the 5 to 10 percent of women who suffer from premenstrual dysphoric disorder (PMDD).   view more (2008-08-19)

Analysis of Lake Washington microbes shows the power of metagenomic approaches
Today's powerful sequencing machines can rapidly read the genomes of entire communities of microbes, but the challenge is to extract meaningful information from the jumbled reams of data.   view more (2008-08-18)

Tiny invasive snail impacts Great Lakes, alters ecology
Long a problem in the western U.S., the New Zealand mud snail currently inhabits four of the five Great Lakes and is spreading into rivers and tributaries, according to a Penn State team of researchers. These tiny creatures out-compete native snails and insects, but are not good fish food... view more (2008-08-11)

You're more likely to do sport if you are white, middle class, and middle-aged
The comfortably off, white, and middle aged are the most likely to participate in sporting activities, reveals a 10 year study published ahead of print in the British Journal of Sports Medicine.   view more (2008-07-24)

Air Quality Forecasts for China
With less than a month remaining before the Beijing Olympics, Chinese officials have introduced a series of measures to improve air quality for the Games. A new tool has been installed in the capital city to allow the Chinese to monitor the effectiveness of these efforts.   view more (2008-07-24)

Exercise could be the heart's fountain of youth
Absence may make the heart grow fonder, but endurance exercise seems to make it younger. According to a study conducted at Washington University School of Medicine in St. Louis, older people who did endurance exercise training for about a year ended up with metabolically much younger hearts.   view more (2008-07-24)

Outflow from World's Largest River - the Amazon - Powers Atlantic Ocean Carbon
Nutrients from the Amazon River's outflow spread well beyond the continental shelf and drive carbon cycling in the tropical ocean, say scientists who conducted a multi-year study. They will publish their results this week online in the journal Proceedings of the National Academy of Sciences (PNAS).   view more (2008-07-23)

Duckweed genome sequencing has global implications
Three plant biologists at Rutgers' Waksman Institute of Microbiology are obsessed with duckweed, a tiny aquatic plant with an unassuming name. Now they have convinced the federal government to focus its attention on duckweed's tremendous potential for cleaning up pollution, combating global warming... view more (2008-07-09)

Alzheimer's disease as a case of brake failure?
Rutgers researcher Karl Herrup and colleagues at Case Western Reserve University have discovered that a protein that suppresses cell division in brain cells effectively "puts the brakes" on the dementia that comes with Alzheimer's disease (AD). When the brakes fail, dementia results.   view more (2008-06-25)

Infant play drives chimpanzee respiratory disease cycles
The signature boom-bust cycling of childhood respiratory diseases was long attributed to environmental cycling.   view more (2008-06-18)

Brief, intense exercise benefits the heart
Short bursts of high intensity sprints-known to benefit muscle and improve exercise performance-can improve the function and structure of blood vessels, in particular arteries that deliver blood to our muscles and heart, according to new research from McMaster University.   view more (2008-06-05)

Molecular 'clock' could predict risk for developing breast cancer
A chemical reaction in genes that control breast cancer provides a molecular clock that could one day help researchers more accurately determine a woman's risk for developing breast cancer and provide a new approach for treatment, UT Southwestern Medical Center researchers have found.   view more (2008-05-14)

Obesity, inactivity as common among cancer survivors as rest of Canadians, study shows
New research supported by the Canadian Cancer Society shows that many cancer survivors in Canada are overweight and inactive, which could put them at risk for health problems, including their cancer returning.   view more (2008-04-21)

Cycling more intelligently
Cycling is fun - if you can find the right tread. But those who tire themselves out quickly lose the desire to conquer the world on two wheels.   view more (2008-04-14)

U of M researchers discover key for converting waste to electricity
Researchers at the University of Minnesota studying bacteria capable of generating electricity have discovered that riboflavin (commonly known as vitamin B-2) is responsible for much of the energy produced by these organisms.   view more (2008-03-04)

Yale study offers new paradigm on ecosystem ecology
Predators have considerably more influence than plants over how an ecosystem functions, according to a Yale study published today in Science.   view more (2008-02-15)

Studying rivers for clues to global carbon cycle
In the science world, in the media, and recently, in our daily lives, the debate continues over how carbon in the atmosphere is affecting global climate change. Studying just how carbon cycles throughout the Earth is an enormous challenge, but one Northwestern University professor is doing his part... view more (2008-02-11)
