Invasion of the island bats

...d organisms were thought to lose their competitive edge and so they hardly ever re-colonized the continent from which they originated. These views suffered a severe blow recently when evolutionary studies of birds of the South Pacific and Caribbean lizards uncovered at least three separate cases of is...

Biologists develop large gene dataset for rice plant

...nd wheat." Research on small RNAs "is a leading edge in plant biotechnology," said Machi Dilworth, Director of the National Science Foundation (NSF)'s Division of Biological Infrastructure, which along with the U.S. Department of Agriculture, funded the research. "This work will contribute to an unders...

Amur leopard still on the brink of extinction, scientists say

... see that its population has been balancing on the edge of survival for many years," said Dr. Dale Miquelle, director of the Wildlife Conservation Society's Russia program and coordinator of the previous census in 2005. "But to understand the reasons, we should research the ecology of the predator in a...

Scientists design simple dipstick test for cocaine, other drugs

...pad. The rehydrated aggregates then migrate to the edge of the membrane, which they cannot penetrate because of their large size. The aptamers quickly bind to any targeted molecules that are present, freeing some of the gold nanoparticles. The red-colored nanoparticles then migrate along the membrane, w...

An artificial cornea is in sight, thanks to biomimetic hydrogels

...crete. They even 'remodel.'" Collagen binds to the edge of the synthetic disc and forms a junction between natural and synthetic tissues. Then a clear layer of epithelial cells grow over the disc. 'Broadly interdisciplinary' Stanford's program to develop an artificial cornea is "broadly interdiscipl...

Protein 'fingerprint' in spinal fluid could spot Alzheimer's disease

The Cornell study combined cutting edge "proteomics" technology, detailed image analysis, and complex computational and statistical analyses to simultaneously compare 2,000 cerebrospinal fluid proteins from 34 patients with autopsy-proven Alzheimer's disease to those of 34 age-matched cont...

Edge density key to controlling gypsy moth spread

...to below the donor threshold." This would decrease edge populations and prevent the periodic surges of growth that expand the territory. Other invading species may also exhibit pulsed spreading. If researchers can determine that the Allee effect is in place, than this same plan of containment might aid ...

Brains can recover from alcoholic damage but patients should stop drinking as soon as possible

...eyond their previous limits, with an outward brain edge shift for the outer regions and an inward shift for the inner ones. "In addition, on average across all the patients, cerebellar choline levels increased by about 20%, while levels of NAA in the cerebellar and frontal region of the brain and front...

Parasitic plants sniff out hosts

...er paper disk. A tomato plant was placed near the edge of the disk and the dodder plant was allowed to grow and attempt to locate its host. Dodder plants search for hosts by growing and moving in a circular pattern. In the past, many assumed that the search was random and the location of a host simply ...

A rice future for Asia

...c backwater, but is, in fact, right on the cutting edge of international scientific activity," Dr. Zeigler said. "The recent sequencing of the rice genome attracted enormous international attention, especially among the scientific community, yet most young Asians still don't know it even happened, let alo...

Ring-like formations in drying DNA drops could affect hybridization studies

...ons. "The DNA alignment parallel to the droplet's edge was counterintuitive," Wong said. "We had expected the DNA to extend along the direction of flow, which was mainly in the radial direction. But, instead of resembling the spokes of a bicycle wheel, the transported DNA resembled the rim of a bicycle w...

Creating a window on 'oceans in motion'

... shelves average about 80 km (50 mi) wide, and the edge of the shelf occurs at an average depth of about 200 m (660 ft), where it falls steeply into the deep sea. Salmon and many other marine animals travel extensively along shelves. A pilot array has been successfully demonstrated by the British Columb...
