Scientists discover new species of distinctive cloud-forest rodent
01-24-2007 · EurekAlert!
A strikingly unusual animal was recently discovered in the cloud-forests of Peru. The large rodent is about the size of a squirrel.The nocturnal, climbing rodent is beautiful yet strange looking, with long dense fur, a broad blocky head and thickly furred tail. A blackish crest of fur on the crown, nape and shoulders add to its distinctive appearance. Two color illustrations of Isothrix barbarabrownae, the bushy rodent, are available to the media.

RIT study predicts how fast a black hole can be booted from a galaxy
05-30-2007 · EurekAlert!
Scientists at RIT have discovered for the first time just how fast a supermassive black hole can be thrown from a galaxy when it merges with another black hole. The crucial factor in producing large "kicks" turns out to be the spin that the black holes carry prior to the merger.Manuela Campanelli and her team derived a formula that for the first time predicts the size and direction of the kick, or radiation recoil.

Killing only a few animals won't do any harm -- or will it?
07-23-2007 · EurekAlert!
Sometimes killing even a few individuals can have dramatic consequences, causing populations to fluctuate wildly. The regulation of populations is usually determined by the properties of one specific size class of individuals. When such a crucial size class is the target of mortality, unexpected things may happen. In harvested cannibalistic fish populations, individuals may reach "giant" sizes, more than double the size of those in unharvested population in heavily fished lakes.

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.

Jefferson researchers develop combined procedure for uterine preservation in treating fibroids
12-05-2006 · EurekAlert!
Although fibroids can cause pelvic pain, abnormal vaginal bleeding and infertility, women of childbearing age often choose to forego treatment because the options don't guarantee fertility.In the December issue of The Female Patient, physicians at Thomas Jefferson University Hospital in Philadelphia present a case history of a 35-year-old woman whose numerous fibroids formed a large mass in her pelvic area that, when initially diagnosed, was of a size comparable to a full-term pregnancy.

Big-brained birds survive better in nature
01-08-2007 · University of Bath
Birds with brains that are large in relation to their body size have a lower mortality rate than those with smaller brains, according to new research by Dr Tamas Szekely from the Department of Biology & Biochemistry published in the journal Proceedings of the Royal Society B: Biological Sciences today.

Humans fostering forest-destroying disease
08-15-2007 · EurekAlert!
Paradoxically, the spread of Sudden Oak Death -- a potentially catastrophic tree killing disease that first invaded California in the 1990s -- is being encouraged by human landscape management practices that have increased the size and density of west coast oak forests, according to a forthcoming study. Research shows that other human activities may be involved as well.

Technique controls nanoparticle size, makes large numbers
12-04-2007 · EurekAlert!
Pratim Biswas of Washington University in St. Louis conducts research on nanoparticles, which are the building blocks for nanotechnology. For the first time, Biswas has shown that he can independently control the size of the nanoparticles that he makes, keeping their other properties the same. He's also shown with his technique that the nanoparticles can be made in large quantities in scalable systems, opening up the possibility for more applications and different techniques.

Human's ecological footprint in 2015 and Amazonia revealed
02-06-2007 · EurekAlert!
In the February issue of Frontiers in Ecology and the Environment, a recent study shows human population size and affluence are the main drivers of human-caused environmental stressors, while urbanization, economic structure and age of population have little effect. In a review in the same issue, researchers review newly revealed changes in the Amazon rainforests and the ecosystem services they provide.

Mind the gap
11-22-2006 · EurekAlert!
Researchers have found a gap between water and a water-repelling surface that can give new insight into the way water and oil separate. By using high-energy X-rays at the ESRF, an international team defined the size and characteristics of this gap. The knowledge of the structure of a hydrophobic interface is important because they are crucial in biological systems, and can give insight in protein folding and stability.
