Emerald Spectre haunts Ontario's ash forests

...of 2002. A native of southeast Asia, the insect is capable of rapidly spreading with a little human help. Adult beetles lay eggs under tree bark and the feeding larvae kill trees by disrupting the flow of nutrients in the soft tissues under the bark. The new study funded by the Natural Sciences and Engineer...

'License to kill' enables powerful immune attack cells in mice

...ies, natural killer cells in mice became much more capable of mounting attacks against invaders after they first encountered the mouse version of MHC. "The structure of these receptors on human natural killer cells is different from the mouse version, but they have a similar function," says lead author Sung...

NHGRI expands effort to revolutionize sequencing technologies

...oup will develop and implement an efficient method capable of sequencing mammalian size genomes by amplifying single template molecules, and subjecting the product to Sanger sequencing and a highly parallel, capillary electrophoresis separation system. Greg Kellogg, Ph.D., Network Biosystems, Woburn, Mass. ...

Tiny avalanche photodiodes target bioterrorism agents

... Devices to create an inexpensive detection system capable of identifying the unique spectral fingerprints of...n of more than 700. The tiny-sized APDs should be capable of efficient detection of light with near single photon precision. Previously, photomultiplier tubes...

European Commission funds EBI to do new research on synergies between bioinformatics and medical informatics

...e new study shows less pathogenic strains are also capable of jumping to humans, giving them the opportunity to swap genetic material with human strains, which could result in a more virulent virus. Researchers in Italy studied outbreaks that occurred among poultry between 1999 and 2003, to determine the r...

Eating, body weight regulated by specific neurons

...e new study shows less pathogenic strains are also capable of jumping to humans, giving them the opportunity to swap genetic material with human strains, which could result in a more virulent virus. Researchers in Italy studied outbreaks that occurred among poultry between 1999 and 2003, to determine the r...

First Whole Genome Map of Genetic Variability in Parkinson’s Disease

Transplanting Animal Organs Could Soon Be A Reality

...e new study shows less pathogenic strains are also capable of jumping to humans, giving them the opportunity to swap genetic material with human strains, which could result in a more virulent virus.

Making plant cells work like miniature factories

...the team must construct new analytical instruments capable of identifying molecules in such minute quantities. "Developing the instrumentation is a large part of the proposal and we're building a special, high-resolution mass spectrometer," Yeung said, "because there's nothing available commercially that me...

UCLA scientists reveal how Nipah virus infects cells

...irus can be used as a potential bioterrorism agent capable of devastating an entire country's public health and economy," said Dr. Benhur Lee, principal investigator and UCLA assistant professor of microbiology, immunology and molecular genetics. "Now that we understand how the virus operates, we can develop...

Vibrio bacteria could be a risk to fish as well as humans

..., only 100 bacterial cells from the pathogens were capable of causing disease. This means that the bacteria are extremely aggressive and could pose a great risk to sea animals, as disease is often caused by enzymes produced by bacteria." It is not yet clear to what extent these new vibrios affect marine ani...

Researchers Create DNA-Based Sensors for Nano-Tongues and Nano-Noses

...they become an extremely versatile type of sensor, capable of finding tiny amounts of a specific molecule." Given the size of such sensors each carbon nanotube is about a billionth of a meter wide, Johnson and his colleagues believe arrays of these sensors could serve as passive detection systems in almost ...

Results of world's first gene therapy trial for arthritis show approach safe, feasible

...ed Maloney Murine Leukemia Virus, has since become capable of replication in their patients. "At the outset, our primary objective was proving the safety of gene therapy, especially for a clinical application to a nonlethal disease, such as arthritis. Once we learned of the adverse events in the X-SCID tria...

Mosquito study shows new, faster way West Nile can spread

...f the West Nile virus in their blood, were thought capable of passing it on to uninfected mosquitoes. "None of the models that have attempted to predict the spread of West Nile virus take into account the possibility that mammals such as horses may be involved in the proliferation of this virus. Direct tran...

'Underground' tunnels discovered as means for communication between immune system cells

Pollution-eating bacteria produce electricity

...rican Society for Microbiology. "The bacteria are capable of continuously generating electricity at levels that could be used to operate small electronic devices. As long as the bacteria are fed fuel they are able to produce electricity 24 hours a day," says Charles Milliken of the Medical University of Sou...

UIC developing drug for SARS

...its advance. Protease inhibitors, a class of drugs capable of disrupting enzymes that digest proteins, have been successfully used to thwart the human immunodeficiency virus, which causes AIDS. "Data from SARS patients indicate that replication of the virus peaks 10 days after the onset of fever," said Mich...

Why do aneurysms form? New studies suggest leading role for white blood cells

...be associated with high levels of enzymes that are capable of doing that eating. But the question of how those enzymes get there, and what prompts them to arrive, has been unanswered. "Neutrophils are known to carry some of these enzymes, called matrix metalloproteinases and chemokines, which help them atta...

Sleeping beauty plays a significant role in identifying cancer genes

...y, he noted that the Sleeping Beauty technology is capable of providing important information about the genes that current methods do not -- such as the specific combinations of mutant genes that can work together to cause cancer. "With this information, we will understand the development of tumors at the ge...
