- Fast and slow -- How the spinal cord controls the speed of movement
02-28-2007 · EurekAlert!
Using a state-of-the-art technique to map neurons in the spinal cord of a larval zebrafish, Cornell University scientists have found a surprising pattern of activity that regulates the speed of the fish's movement. The research may have long-term implications for treating injured human spinal cords and Parkinson's disease, where movements slow down and become erratic.

- Fisheries Linked To Decline In Galapagos Waved Albatross Population
10-09-2006 · ScienceDaily
Fishermen caught and killed about 1 percent of the world's waved albatrosses in a year, according to a new study by Wake Forest University biologists. The research shows the waved albatrosses are unintentionally killed when caught in fishing nets or on fishing hooks, but are also intentionally harvested for human consumption.

- A chilling solution -- Measuring below-ground carbon without destroying trees
12-05-2006 · EurekAlert!
USDA Forest Service (FS) researchers have provided the first proof of concept for a method that allows scientists to study below-ground carbon allocation in trees without destroying them. In the latest issue of the journal Plant, Cell & Environment, Kurt Johnsen and fellow researchers at the FS Southern Research Station unit in Research Triangle Park, NC, describe a reversible, non-destructive chilling method that stops the movement of carbon into root systems.

- Predicting the perfect predator
02-13-2008 · EurekAlert!
Garlic mustard has become an invasive species in temperate forests across the United States, choking out native plants on forest floors and threatening ecosystem diversity. University of Illinois ecologist Adam Davis has created a computer model that in combination with quarantined research tests he believes will be able to predict the perfect predator -- a pest that can be introduced into a forested area that will help reduce the garlic mustard population.

- Ecologists discover city is 'uber-forest' for big owls
10-16-2007 · EurekAlert!
Charlotte has a spooky secret: the North Carolina city is home to a robust population of very large barred owls -- a species long-believed by ornithologists to require old growth forest for survival. According to ecologists doing the most extensive field study ever done on the species, the owls see urban life as an upgrade on the old woods, and Charlotteans are not at all creeped out by the big birds that share their yards.

- Paper challenges 1491 Amazonian population theories
03-06-2007 · EurekAlert!
There's a scholarly debate brewing about whether pre-Columbian Amazonian populations settled in large numbers acrossAmazonia and created the modern forest setting that many conservationists take to be "natural." The view is challenged in a recent paper from Dr. Mark Bush of the Florida Institute of Technology. His findings may rekindle a debate has major implications for land use and policy-setting in the rain forest.

- Biofeedback treats one type of chronic constipation
04-02-2007 · EurekAlert!
Chronic constipation affects 15 to 20 percent of the US population. Nearly one-third of affected people have dyssynergic defecation, in which muscles used for bowel movements do not work well, but there's some good news. University of Iowa research shows biofeedback treatment can successfully retrain muscles.

- First study transplanting angina patients' purified stem cells shows safety and symptom relief
06-26-2007 · EurekAlert!
The first U.S. study to transplant a potent form of purified adult stem cells into the heart muscle of patients with severe angina provided evidence that the procedure is safe and produced a reduction in angina pain as well as improved functioning in patients' daily lives, reports Northwestern University. The procedure was an effort to spur regrowth of small blood vessels that constitute the microcirculation of the heart muscle.
