Brain's white matter -- More 'talkative' than once thought

...discovered that as electrical impulses are carried along the nerves, glutamate is released and causes electrical signals in the OPCs. A further microscopic hunt revealed that pools of glutamate were present in the nerve fibers wherever they touched OPCs. All of the nerve cells in the white matter that rele...

Targeting sugar on blood vessels may inhibit cancer growth

...the growth of vasculature. The drug has been used along with chemotherapy in humans to successfully inhibit the growth of tumors in colon and lung cancers. "If novel drugs can be developed to target tumor heparan sulfate, we might be able to make a leap in cancer-fighting therapies, because several mol...

Newborn neurons like to hang with the 'in' crowd

... structures called synapses. As a signal traveling along a nerve branch arrives at the pre-synaptic area, it releases a chemical signal. The signaling molecules travel across the synapse and induce a signal on the neighboring, receiving nerve fiber or dendrite. A typical neuron sports about 7,000 synapses ...

UQ research heralds vaccine technology breakthrough

...the research project was double-barrelled because, along with helping children, it included forming a new type of vaccine. The research group has developed a "recombinant" vaccine using the existing Hepatitis B vaccine to carry the RSV peptides. "Hepatitis B surface antigen forms virus-like particles, wh...

Healthy coral reefs hit hard by warmer temperatures

...ked an infection called white syndrome in 48 reefs along more than 900 miles (1,500 kilometers) of Australia's coastline. The colorful coral colonies that attract visitors to the Great Barrier Reef live atop a limestone scaffolding built from the calcium carbonate secretions of each tiny coral, or polyp...

New bacteria test could improve quality of fruit and vegetable juice

.... This has complicated international trade. Japan, along with other developed countries, has a zero tolerance for this bacterium in imported juices, Lin said. He said identification is a challenge because spoilage can be difficult to distinguish visibly until test results are confirmed or ...

Scientists identify prion's infectious secret

...it other, properly folded proteins into misforming along with them, a process Lindquist calls a "conformational cascade." In many organisms, this conformational cascade creates long fibers called amyloids. (The brains of animals that have died from prion infections are literally packed with amyloid clumps....

UCLA AIDS Institute researchers find a peptide that encourages HIV infection

...peptides, the amino acids are strung like 18 beads along the molecule's backbone. The amino acids in RC-111, however, are in reverse order. The researchers had initially wanted to quantify previous research by Dr. Robert I. Lehrer, distinguished professor of medicine in the division of infectious disea...

'Short-circuit' found in ocean circulation

...bination of rapid mixing across and rapid movement along density surfaces creates a 'short-circuit' in the overturning circulation, meaning it is more concentrated in this part of the Southern Ocean. The researchers made use of a unique signal - the spread of helium released naturally from the Earth’s ...

Tissue engineered scaffolding allows reproduction of cartilage tissue

...into the body, where new cartilage tissue is grown along the structure. The study appears in the journal Artificial Organs. The procedure was extremely successful in tested mice as the study found these scaffolds to be a far more effective means of regenerating cartilage than traditional therapy. The shri...

...ollow the passing of natural shear waves traveling along the muscle fibers. By the way, the Scripps scient...ble paths as they travel from location to location along the west coast of North America. Transients, which also distinguish themselves by feeding primarily ...

From the deep -- Researchers find new species of sea anemone

...hat there are now far fewer major whale migrations along the California coast. While the flesh of a dead whale decomposes within weeks, the bones can last anywhere from 60 to 100 years. "As that happens, the bacteria that break down the bones release sulfur," Daly said. "A whole community of aquatic ...

Study warns deep-sea mining may pose serious threat to fragile marine ecosystems

... "The demand for metals is growing rapidly, and along with the sharp rise in metal prices, we have seen the depletion of metal-rich terrestrial mines," says Halfar. "For mining companies and their investors, undersea mining offers high concentrations of ore at relatively low production costs." The mi...

Cornell lab confirms deadly fish virus spreading to new species

... dead freshwater drum formed windrows of carcasses along the beaches of Lake Erie in 2006, all victims of VHSV. Other species from the Great Lakes Basin area that have tested positive by Cornell include bluegill, rock bass, black crappie, pumpkinseed, smallmouth and largemouth bass, muskellunge (New York...

Danish researches solve virus puzzle

Switching genes to overdrive improves muscular dystrophy symptoms in mice

..., PhD, the Dana-Farber researcher who led the team along with Christoph Handschin, PhD, formerly of Dana-Farber and now at the University of Zurich. Other authors are from the University of Iowa College of Medicine. Duchenne muscular dystrophy (DMD) is the most common type of muscular dystrophy in child...

In Iran, cheetahs collared for the first time

...rey during the early years of the 1979 revolution, along with degradation of habitat due to livestock grazing, have pushed this important predator to the brink of extinction. Historically cheetahs have played a significant role in Iranian culture, being trained by its emperors to hunt gazelles in ancient ...

Leeches ferry infection among newts

...ech's proboscis, and the infection would be passed along to the next newt the leech bites." The researchers point out that Ichthyophonus might not be as contagious as other leech-transmitted amphibian parasites. That is because this particular parasite lodges itself in muscle tissue instead of blood. A ...

Tibetan antelope slowly recovering, WCS says

...nged between 16,000-17,000 feet. There, Schaller, along with WCS staff member Aili Kang and a team of Tibetan and Han-Chinese biologists and field assistants, counted nearly 9,000 Tibetan antelope or chiru, more than expected. This may indicate an increase in some places for this endangered species, acco...
