Hotspots of mercury contamination identified in eastern North America

...some wildlife species. Fish consumption advisories responding to mercury contamination exist in all the states and provinces included in the study, and loons are adversely affected by mercury levels they experience. The hotspots have implications for "cap and trade" approaches being implemented for regulation o...

LIAI completes world's most comprehensive analysis on influenza virus data

... used one time, for example by a single individual responding to a single virus, or 100 different times. Now, scientists can search the database and find out all existing information on their particular topic. This will enable them to avoid unnecessary repetition and make faster progress toward new therapies ...

Protein's effects essential for kidney-to-bladder urine transfer

...uld be making the DLGH1 themselves, or they may be responding to cues from other cells that make the protein. "We have to answer that question before we can get serious about figuring out how this process works at a molecular level," Swat says. ...

Committee review of stem-cell fraud finds editors followed all rules

"In responding to the recommendations, we are now moving to develop criteria for the 'risk assessment' template described in the Report which should allow us to apply especially stringent attention as needed." In the future, he explained, "Authors may be asked to d...

... of the granulomas by preventing immune cells from responding aggressively and destroying the granuloma. Furthermore, decreased expression of the immunosuppressive factor IDO, and therefore decreased granuloma integrity, might explain why individuals treated with TNF-blocking agents (such as individuals with rh...

Global warming increases species extinctions worldwide

..., trees or butterflies, you're seeing some species responding strongly and some staying fairly stable," said Parmesan. "But within each group you're still seeing about half of the species showing a response. It's a very widespread phenomenon."...

Mysterious 'neural noise' actually primes brain for peak performance

...s to call the noise "variability." Our neurons are responding to the light, sounds, and other sensory information from the world around us. But if we want to do something, such as jump over a stream, we need to extract data that is not inherently part of that information. We need to process all the variables we...

Researchers identify cells that make relapse inevitable in acute lymphoblastic leukemia

White blood cells of cancer-resistant mice overwhelm natural defenses of cancer cells

...ffusible and surface signals from cancer cells and responding to those signals by migration and physical contact," they said. The researchers said that in ordinary mice, the white blood cells are suppressed by self-defensive signals coming from the cancer cells and don't attack the cancer. But the mutated gene...

The CReSA is working on a new strategy to combat spongiforms

...he "memory", enabling the animal cells to continue responding to the infectious agent). The main obstacle to achieving this objective is that the prions do not produce an immune response since the metabolism of the affected animal identifies it as one of its own antigens. The challenge, therefore, is to overc...

Urgent call to action issued to protect world's most vulnerable populations from influenza pandemic

"They seek to ensure continuity of basic needs, relief services, economic system...

Slow brain waves play key role in coordinating complex activity

... Institute at UC Berkeley. "A simple activity like responding to a question involves areas all over the brain that hear the sound, analyze it, extract the relevant information, formulate a response, and then coordinate your lips and mouth to speak. We have no idea how information moves between these areas." By...

Existing vaccine facilities can handle flu pandemic

...nd capacity, both of which are critical factors in responding to a pandemic, researchers said. It takes much longer to compile millions of hen eggs than it would to grow up existing cell lines from frozen vials, Lash said. While cell culture has a lower yield than egg culture, there is more existing capacity fo...

Chemical tests of cell growth enter third dimension

... easily tell if cancer cells in the laboratory are responding to an anti-cancer drug. The second -- because it tests several sets of cells at once -- allows for the simultaneous testing of different dosages, or the effect of a single drug on different kinds of cells taken from the body.

Abnormal overexpression of p53 is a predictive molecular biomarker

...on." "Selecting those who have the best chance of responding to p53 tumor suppressor gene therapy also helps perfect clinical trial testing," Licato said. The researchers specifically found, in a subset of patients from phase II clinical trials, that 73 percent of patients with p53-positive tumors responded t...

Biomarkers of response to VEGF pathway-targeted therapy discovered for renal cell carcinoma

...but researchers have not been able to identify the responding patients, prior to treatment. Now, a research team from the University of California, San Francisco (UCSF) and the Cleveland Clinic, has found that patients whose tumors produce greater amounts of vascular endothelial growth factor (VEGF) and its re...

Islands spark accelerated evolution

... It appears that some mainland species are already responding like island species: a 1989 study followed the island rule in linking fragmented habitat to body size changes in 25 European mammals over the past 200 years. How long animals can continue to evolve in the face of these changes, however, remains to be...

'Empty nester' parent birds use recruitment calls to extend offspring care

...fledglings to rich, divisible food sources (adults responding to the calls often met with aggression from the caller). The researchers found that fledglings that responded to this call were much more successful than those sticking to areas chosen by themselves. This work shows that recruitment calls by adult bi...
