Ecologists uncover links between fever and living fast, dying young
10-29-2007 · EurekAlert!Fever is an effective defence against disease, but new research suggests that not all animals use it when exposed to infection. The study, published online in the British Ecological Society's journal Functional Ecology, found large differences in fever responses among closely related species of mice and suggests that an animal's reproductive strategy could explain some of this intriguing variation.

- Ecologists work to link kids with nature
08-07-2007 · EurekAlert!
Now ecological scientists -- well-positioned because of their field of study -- are stepping up to do their part. The symposium "No child left indoors: Ecologists linking young people with nature" will feature eight case studies offered by ecologists of different ages, races, and cultures and employing different outreach tools. Case studies will range from outdoor laboratories in Montana, to inspiring kids via tree canopy walkways, to community restoration activities on Catalina Island in California.

- Scientists uncover how hormones achieve their effects
10-22-2007 · EurekAlert!
New insights into the cellular signal chain through which pheromones stimulate mating in yeast have been gained by scientists at the European Molecular Biology Laboratory. Similar signal chains are found in humans, where they are involved in many important processes such as the differentiation of nerve cells and the development of cancer. A sophisticated microscopy technique allowed the researchers to observe for the first time the interplay of signalling molecules in living yeast cells.

- Relative abundance of common microbes living in the gut may contribute to obesity
12-20-2006 · EurekAlert!
A link between obesity and the microbial communities living in our guts is suggested by new research at Washington University School of Medicine in St. Louis. The findings indicate that our gut microbes are biomarkers, mediators and potential therapeutic targets in the war against the worldwide obesity epidemic.

- Sports concussion research using fMRI provides insight for safe return-to-play decisions
08-06-2007 · EurekAlert!
Concussions are common in young athletes but the underlying changes in brain function that occur have been poorly understood. Now, a University of Pittsburgh study is the first to link changes in brain function directly to the recovery of the athlete. The study results confirm that changes in brain function seen on fMRI may be reliably measured by neuropsychological testing, a tool commonly used nationwide by team doctors in making critical decisions about safe concussion management.

- Baltimore inner-city homes unsafe for young children, Hopkins study finds
07-24-2007 · EurekAlert!
Infants and young children living in Baltimore's inner-city homes are at risk for serious perils, including fires, falls and poisoning, according to a small but revealing study from the Johns Hopkins Children’s Center. A survey of 32 urban homes found that many lacked functioning fire alarms, staircase gates and safe storage for medications, researchers report in the August issue of Pediatrics. Fires, falls and poisonings are the top causes of childhood home injuries in Baltimore.

- Dead clams tell many tales
10-29-2007 · EurekAlert!
Inventories of living and dead organisms could serve as a relatively fast, simple and inexpensive preliminary means of assessing human impact on ecosystems. The University of Chicago's Susan Kidwell explains how measuring the degree of live-dead mismatch could be used as an ecological tool in the Oct. 26 early online edition of the Proceedings of the National Academy of Sciences.

- First-ever study to link increased mortality specifically to carbon dioxide emissions
01-03-2008 · EurekAlert!
A Stanford scientist has spelled out for the first time the direct links between increased levels of carbon dioxide in the atmosphere and increases in human mortality, using a state-of-the-art computer model of the atmosphere incorporating scores of physical and chemical environmental processes. The new findings, to be published in Geophysical Research Letters, come to light just after the Environmental Protection Agency's recent ruling against states setting specific emission standards for this greenhouse gas.

- Emergency responses greatly increase risk to firefighters of dying on duty from heart disease
03-21-2007 · EurekAlert!
In a new, large-scale study, researchers from the Harvard School of Public Health examined the link between CHD deaths and firefighting and looked at specific job duties to see which might increase the risk of dying from a coronary event. The landmark study provides the strongest link to date between CHD and emergency firefighting duties. It found that putting out fires was associated with a risk about 10 to 100 times greater than the risk of dying from nonemergency duties.
