Microbes compete with animals for food by making it stink

...rt." Hay hopes the research will make ecologists think more critically about the broad role of microbes in the ecosystem. Microbes are often omitted or relegated to a minor role in food web diagrams, but they should be depicted as direct competitors with larger animals, he said. ...

ASU researchers test antibacterial effects of healing clays

.... "People are interested in natural cures and I think that there is a lot of nature that we don't understand yet," Williams says. "What if we discover a mechanism for controlling microbes that had never been discovered before? It is these avenues, at the boundaries of scientific discovery, at the edges ...

Free drug samples influence prescribing, say one in three doctors

... in the Journal of Medical Ethics. But they also think that other doctors are more likely to be influenced by incentives than they are, the data show. In March 2003, the research team surveyed 397 members of the American College of Obstetricians and Gynecologists about their relationships with the phar...

One-of-a-kind imaging probe reveals secrets useful for drug discovery

...t is now possible to approach problems we couldn't think about before," said Edison, who said he welcomes collaboration with other scientists interested in using the new probe. "For example, in mouse models of Parkinson's or Alzheimer's disease, there is not a lot of tissue to work with, especially if you'...

Novel experiment documents evolution of genome in near-real time

...witness evolution actually occurring, as we did, I think they'd be more likely to believe that it's not just a theory."...

Men with prostate cancer avoid radiation due to misconceptions

...rays would affect them. For example, some patients think that radiation cannot be controlled because it is invisible, that it will harm surrounding unprotected organs and that it is dangerous for family members to physically be near them when undergoing radiation treatment. Patients also said that the term...

Scientists crack rhino horn riddle

...g of horn for the black market. "Ultimately, we think our findings will help dispel some of the folk wisdom attached to the horn. The more we can learn about the horn, the better we can understand and manage rhino populations in the wild and in captivity," said Lawrence Witmer, a professor of anatomy in...

Mutant gene causes severe kidney disease in infants

...se of treatment. Based on this information, we now think that there may be a critical time window during which treatment can overcome the development defects caused by PLCE1's loss of function." The discovery has important implications for pediatric nephrologists and pediatricians who treat infants with...

Invasive ants territorial when neighbors are not kin

... other colonies of Argentine ants. The biologists think that the distinct supercolonies in southern California arose from separate introductions of the ants, possibly in the soil of plants used in landscaping. They hope that a better understanding of how the ants distinguish kin from non-kin, and the me...

Math model predicts cancer behavior

... can do so little: why is that"" Quaranta said. "I think the reason is that we need additional tools, and those are the tools of mathematics." The team's model is an initial effort. It is sophisticated enough to begin capturing tumor behavior, without being so complicated that computing power and running...

Uncovering DNA's 'sweet' secret

.... There are hundreds of sugars, as many as you can think of. It will be almost impossible to look at all of them," Egli said. "But the big red herring of this work could be that nature never went through these other sugars. Maybe it just hit on gold (these five-carbonsugars) very early and took off from ...

Einstein researchers demonstrate a novel approach to treating AIDS

...a combination of therapies--then we could start to think about curing HIV-infected patients." Dr. Goldstein, also a senior author of the study, notes that radioimmunotherapy might be particularly useful for people newly exposed to HIV, such as healthcare workers with needlestick injuries. "Studies show ...

Researchers seek to design first treatment for neuroAIDS

...V infection that lessens many patients' ability to think and move. As evidence of the progress, researchers at the University of Rochester Medical Center today received a $7 million grant to confirm that two new drug classes can protect the brain from HIV-related nerve damage. Driving their approach is the...

Anticipation plays a powerful role in human memory, brain study finds

... is anticipating a difficult situation. Scientists think the amygdala is associated with the formation of emotional memories, while the hippocampus helps the brain form long-term recollections, Nitschke says. The researchers studied the brain activity of 36 healthy volunteers using a technique known as f...

Peering into the shadow world of RNA

...number of RNA editing sites,?she says, “but now we think there may be as many as 20,000 sites involving perhaps 3,000 genes. Interestingly, most of the editing sites correlate with non-coding regions of DNA, the so-called junk DNA.? One reason for this, Nishikura and others speculate, may be that the maj...

Transplanted brain cells hold promise for Parkinson's disease

...ble to identify Parkinson’s in the early stage, we think this therapy will work. An important question that remains is, ‘Can we rescue neurons that are dying from Parkinson’s"?This would more accurately mimic what patients need." The researchers already have begun studies that delay the transplants until w...

Researchers link ocean organisms with increased cloud cover and potential climate change

..."Studies like this one may help reshape the way we think about how the biosphere interacts with clouds and climate," said Nenes, an assistant professor in Georgia Tech's School of Earth and Atmospheric Sciences. "One of the largest uncertainties right now in climate models is the ability to predict how cl...

Vaccination with embryonic stem cells prevents lung cancer in mice

Who gives stem cells their marching orders?

...f embryonic stem cells. Constam and his colleagues think that the signaling pathways used by tumor cells to migrate and invade new territory might be similar to those used in the embryonic development of the organism. Recent research from Northwestern University seems to confirm this, showing that aggressi...
