Ancient retrovirus sheds light on modern pandemic

...en them. They then used this information to make a partial viral genome. During reconstruction the viral segment was debilitated, enabling only one round of infection in cells. Working with cells in the laboratory, the researchers found that the human antiviral protein TRIM5a effectively neutralizes this ext...

Researchers use MRI to predict recovery after spinal cord injury

...gists can better predict the likelihood of full or partial recovery of patients with acute spinal cord injuries (SCI), according to a study published in the June issue of the journal Radiology. "Our study demonstrates that the possibility and extent of neurological recovery after SCI can be predicted withi...

Stanford-led study closes in on genes that may predispose some people to severe depression

...some people, but there are others who have only a partial response or no response at all," he said. "Understanding the biology would help the search for better treatments." The next phase of the consortium's research is already under way. This phase is an even more detailed look at more than 2,000 in...

Study suggests some drug resistance to influenza B medications

...ic in Japan showed the development of viruses with partial resistance to the drugs, according to a study in the April 4 issue of JAMA. Two antiviral drugs, zanamivir and oseltamivir, which are a type of drugs known as neuraminidase inhibitors, have been effective against influenza and are used extensively. ...

Arsenic in chicken feed may pose health risks to humans, C&EN reports

...olon cancer, while low-level exposures can lead to partial paralysis and diabetes, the article notes. Use of roxarsone has become a topic of increasing controversy. A growing number of food suppliers have stopped using the compound, including the nation’s largest poultry producer, Tyson Foods, according ...

Robotic exoskeleton replaces muscle work

...unction, which is encouraging news for people with partial nervous system impairment, say University of Michigan researchers. The ankle exoskeleton developed at U-M was worn by healthy subjects to measure how the device affected ankle function. The U-M team has no plans to build a commercial exoskeleton, bu...

New species declared: Clouded leopard on Borneo and Sumatra

...or, with a tendency toward tawny-colored fur and a partial double dorsal stripe. “Who said a leopard can never change its spots? For over a hundred years we have been looking at this animal and never realized it was unique,?said Adam Tomasek, head of WWF’s Borneo and Sumatra program. “The fact that Born...

New UD technology removes viruses from drinking water

...rchers decided to pursue some experiments. With partial support from the U.S. Department of Agriculture and the Delaware Water Resources Center, through its graduate fellowship program, the scientists and their students began evaluating the effectiveness of iron granules in removing viruses from water und...

Discovery of the first resistance gene to rice yellow mottle virus

... results show that the transgenic plants have only partial resistance, and for only a short time, and can even end up with a heightened susceptibility. In the particular case of the rice/RYMV interaction, the strategy of introducing a viral gene by transgenic techniques does not bring any advantages compared...

First Biodiversity Census of coral reef ecosystems in the NW Hawaiian Islands

Information from this effort will be posted on the CReefs website at www.creefs.org , and the cruise can also be followed at www.hawaiianatolls.org and http://sanctuaries.noaa.gov/ . Further...

New dwarf buffalo discovered by chance in the Philippines

...he size and features of the new species based on a partial skeleton consisting of two teeth, two vertebrae, two upper arm bones, a foot bone, and two hoof bones. The fossil could not be dated with certainty, but the authors estimate that it probably lived during the Pleistocene ("Ice Age"), probably between ...

MRSA vaccine shows promise in mouse study

...lected bacterial subunits, produced, at best, only partial immunity. "For S. aureus vaccines to succeed," sa...a vaccine, each of the four proteins provided only partial or no protection. Fifty to 70 percent of mice vaccinated with one of these proteins and injected wi...

Massive duplication of genes may solve Darwin's 'abominable mystery' about flowering plants

...omes of a number of plant species for which only a partial DNA sequence has been determined. The team uncovered evidence of whole-genome duplications by confining their study to duplicated genes. The challenge was to distinguish isolated duplications from whole-genome duplications after a period of time in...

How ancient whales lost their legs, got sleek and conquered the oceans

...Sonic hedgehog required to grow a complete or even partial limb, although it is active elsewhere in the embryo. The team also showed why Sonic hedgehog became inactive and all traces of hind limbs vanished at the end of this stage of whale evolution, said Cohn. A gene called Hand2, which normally functions ...

Brain enzyme treatment relieves memory lapse in Alzheimer's mice

... initiates a signaling cascade that results in the partial inhibition of proteasome activity more rapidly than is likely as the result of the accumulation of misfolded or undigestable proteins." "Our data suggest that Uch-L1 could be an attractive target for the development of new therapeutic approaches to...

Plastic surgeons countdown first full facial transplantation

New method enables gene disruption in destructive fungal pathogen

...y selection of the new mutants, as well as a short partial target gene that integrates and disrupts genes in the pathogen's genome. Richard Oliver, director of the Australian Centre for Necrotrophic Fungal Pathogens and professor of Molecular Plant Pathology at Murdoch University, Perth, commented: "The ne...
