UN successfully tests 'green' pesticide against locusts

...ture competes with formation of the DNA constraint until a chemical balance is reached," Silverman said. "In some cases, the DNA is like a barnacle, just stuck onto the RNA without perturbing its structure. In other cases, the DNA changes the RNA structure. We can predict which situation will occur based o...

New miniaturised chip dramatically reduces time taken for DNA analysis

... analysis already takes place in laboratories, but until now the experimental measures needed were not suitable for in situ analysis. By using the new sensors developed by UAB scientists, the time taken to identify the source of infection for Legionella would decrease from two days, as is currently the cas...

Survey reveals women and doctors aren't talking about HPV

...s in their lifetime, in some cases staying dormant until years after the initial infection. Yet few are talking about the relationship between HPV and cervical cancer despite the fact that advanced screening is available, which can detect the virus early and help prevent cervical cancer. "The communicatio...

Understanding how bacteria communicate may help scientists prevent disease

...changes in behavior," he said. What was not known until recently is a crucial missing link in the network in each bacterium that results in the ability to change behavior. Just before he came to Virginia Tech in August 2004, Kulkarni and his collaborators at Princeton solved the mystery. Using bioinformat...

New understanding of cell movement may yield ways to brake cancer's spread

From birth until death, our cells migrate: nerve cells make their vital connections, embryonic cells move to the proper places to form organs, immune cells zero in to destroy pathogenic organisms, and cancer cells metastasize, spreading deadly disease through the bod...

U of T researchers map role of Epstein-Barr virus in cancer

...een shown to work through this p53 protein, but up until now, no one's ever found any regulation of p53 that's associated with the Epstein-Barr virus. That was surprising because all other viruses that stimulate cell proliferation do it through p53. The question was why this one didn't. What our research s...

Immune system's distress signal tells bacteria when to strike back

...hat "bacteria are perfectly content in their niche until signals from the host ?usually during stress, such as after major surgery ?let them know there's a problem." For Pseudomonas, detecting interferon-gamma, "is like receiving a demolition notice from your landlord," Alverdy said. "It lets them know th...

Research on antibiotics receives historical recognition

... studied actinomycetes in the soil, but it was not until late 1930s that he turned his attention to the searching for microbes that attacked other microbes. Waksman received the Nobel Prize for physiology or medicine in 1952 for "ingenious, systematic and successful studies of the soil microbes" that led ...

Bacterial genome sheds light on synthesizing cancer-fighting compounds

...sea squirt produced the sought-after patellamides, until now. By searching for patellamide synthesis instructions in genomic sequences, scientists found the bacterium indeed has the necessary genes to produce these potentially important biochemicals, solving the source mystery. Knowing which genes Prochlo...

Stem cell therapy successfully treats heart attack in animals

...sites across the country. Results are not expected until mid-2006. "Ultimately, the goal is to develop a widely applicable treatment to repair and reverse the damage done to heart muscle that has been infarcted, or destroyed, after losing its blood supply," says cardiologist Joshua Hare, M.D., professor o...

Combination therapy leads to partial recovery from spinal cord injury in rats

...ired function after a spinal cord injury. However, until now it has not been clear whether promoting new myelin growth in the spinal cord can reverse this damage, says Scott R. Whittemore, Ph.D., of the University of Louisville in Kentucky, who led the new study. "Many other investigators have suggested th...

Scientists inhibit cancer gene

... to inhibit activated Ras have had limited success until now, but the Huntsman Cancer Institute researchers explain that they have discovered an enzyme that, when inhibited, appears to reduce the incidence of Ras-induced tumors in mice. They reported their findings in the May 9 - 13, 2005, issue of the jo...

By creating molecular bridge, scientists change function of a protein

In total, Zhao and Chen did four rounds of random mutagenesis and screened about 1 million mutants before they found two estrogen receptor mutants that can be activated by corticost...

Where Bacteria Get Their Genes

...ial world, has long been recognized as common. But until now scientists did not know which of a bacterium's genes came from lateral gene transfer and which had been inherited from its parent. In their study, the scientists focused on the best-studied group of bacteria, the Gamma-Proteobacteria. It include...

The researchers collected the fluid through a cannula, a surgically implanted tube that leads directly from the cow's hide into its rumen. The cow used in the study...

Bacteria feed on smelly breath (and feet)

The researchers found no difference between strains of bacteria found in the mouths of healthy volunteers and those suffering f...

When it comes to cell entry, being average has its advantages

The process is believed usually to involve clathrin, a protein that coats the invader to aid in the Velcro-like fastening. Yet scientists have shown that flu virus...
