...er animals from cheating by displaying a mark that indicates "I'm great" while actually being just average. Scientists hypothesize that social interactions discourage cheating, but demonstrations of such interactions have been elusive. Tibbetts noticed that for wasps in the species Polistes dominulus, the faci...

Drug may hinder recovery from heart attacks

...nase-2 (COX-2). The work from the Casey laboratory indicates that the reported side-effects of celecoxib may result from their unintended inhibition of the body's ability to move bicarbonate. The work was headed up by principal researcher Joe Casey, a University of Alberta physiology professor. Bicarbonate (HC...

Old riverbed keeps chemicals from entering Ohio River

Beneath sand and gravel on the grounds of Barium and Chemical Inc. in Steubenville, OH, lies an aquifer that contains chemicals such as nitrate and barium t...

Reassuring findings from first study on sperm donor identification

...rivacy and not intruding on his life. This finding indicates that the stereotypical concern of offspring showing up on the donor's doorstep is inaccurate and does not reflect the intentions of the actual youths going through the identity-release process." Dr Scheib said that the practice of open-identity sperm...

Rethinking new therapies for Crohn's disease at U.Va.

...ng inflammation of the intestines. Cominelli indicates that more cytokines- proteins that coordinate the immune response in inflammation- may be involved in Crohn's than scientists had previously thought. He believes that a growing body of evidence shows that both type 1 and type 2 helper T-cells are lik...

New study links low fish supply to increased bushmeat hunting

...sh prices were high when fish availability was low indicates that the link with high bushmeat sales was driven by low fish supply," said Andrew Balmford, senior lecturer in conservation biology at the University of Cambridge and co-author of the report. "It is the evidence for each of the links in the chain th...

Ancient fossil offers new clues to brown bears past

The recent findings and their implications, are the subject of an article in the Nov. 12 issue of the journal Science titled Pleistocene Brown Bears in the Mid-Continent of North...

New gene therapy promising for treating Fabry disease

...d fat reduction in target organs. "Current thought indicates that approximately a five per cent level of normal enzyme activity is enough to correct the disorder," says Medin. In a parallel study, Medin and his colleagues were able to monitor gene therapy vector activity in treated live mice at various points ...

...elded from host defensemechanisms. "The literature indicates that 500 to 5,000 times higher levels ofantibiotics are needed to achieve the same antimicrobial effects onbiofilm organisms as on planktonic microorganisms," say the researchers. In the study researchers examined whether or not electric currents(dir...

The lost genetic legacy of American gray wolves

Unfortunately, the new research indicates that the genetic diversity of historic US wolves was much greater than that of contemporaneous Canadian wolves because historic US wolves lived in an Ice Age, rich in genetic diversity. Approximately 400,000 wolves existed historically in the western...

A new species of amyloid peptide

Dr. Xu explains that the literature indicates amyloid β-peptide itself could be toxic to synapses and the accumulation of amyloid β-peptide could initiate a series of events contributing to cell death, including activation of cell death programs, oxidation of lipids and disruption of c...

New findings in innate immunity may lead to treatments for atherosclerosis

IRAK1 may provide a viable target for developing therapeutic interventions for atherosclerosis. Compounds or strategies directed at pre...

US trees affected by growing number of health concerns

...to reduce the spread of this disease, research now indicates that the pathogen that causes this disease is moving into new areas and finding new hosts. White pine blister rust enters through needles and bark and forms cankers on the branches and trunks, eventually causing death. Rare pines in fragile ecosystem...

In the ten square kilometers surrounding Los Ajos alone there are ten other large and spatially complex mound sites. These were thriving societies that probably were integrate...

...lls to act against tumor-derived cells. This data indicates that NK cells are key players in tumor surveillance in such malignancies. The authors suggest that people deficient in TYK2 may be predisposed to the formation of tumors. In addition, the absence of TYK2 in patients would predict a reduced response t...

Common lineage suggested for viruses that infect hosts from all three domains of life

While viral lineage is in itself a question that interests scientists, research in this area may ultimately inform anti-viral drug discovery. Structural similarities in viruses may point to sites of enzymatic activity that could be ...

To show that this approach could be used t...

Efforts to clone primates move forward

...ver, and the Pittsburgh team's experience thus far indicates the possibility for successful cloning of primates (and perhaps humans) is even more remote than previously believed. Dr. Schatten's group made 135 cloned monkey embryos and transferred them into 25 surrogate female rhesus macaques. No pregnancies w...

Study urges caution in contaminant source tracking

But several testing methods using E. coli to identify the sources of fecal contamination were less accurate in field application than previously rep...
