New Look at DNA Hints at Origin of UV Damage

...mals. "The importance of our work is that it will permit us to use a model whose genetics can be easily manipulated as a viable alternative not only for the identification of novel Y. pestis virulence factors but also to study conserved innate immune responses to the bacterium," Aballay said. "This may hel...

Researchers Discover That Microbes Can Produce Miniature Electrical Wires

...miniature wires extending from the cell that would permit Geobacter to carry out its unique ability to transfer electrons outside the cell onto metals and electrodes. This was confirmed in a study in which microbiologist Gemma Ruegera teamed with physicists Mark T. Tuominen and Kevin D. McCarthy to probe th...

Scientists reveal how disease bacterium survives inside immune system cell

...eutrophils, dictate whether our immune system will permit or prevent bacterial infections. A paper describing the research was released today online in The Journal of Immunology. Frank R. DeLeo, Ph.D., of Rocky Mountain Laboratories (RML), part of the National Institute of Allergy and Infectious Diseases (N...

Team Invents Device For Weighing Individual Molecules

... do with cancer." The new method might ultimately permit the creation of microchips, each possessing arrays of miniature mass spectrometers, which are devices for identifying molecules based on their weight. Today, high-throughput proteomics searches are often done at facilities possessing arrays of conven...

Study of energy and health in Africa focuses spotlight on charcoal and forest management

...ys going out in the woods, almost always without a permit and on somebody else's land, cutting down a tree or two, chopping it up, lighting it, covering it with dirt, and then hovering around it for two to four days while it becomes charcoal," Kammen said. "It's no surprise it's not generally a high-efficie...

Tendency to hair loss inherited from the mother

...ore androgen receptors in the scalp. "Our findings permit two explanations," Axel Hillmer from Prof. Nöthen's team explains. "Either more androgen receptors are formed among the men affected, or the variant of the receptor which develops as a result of the genetic change is more stable and is not broken dow...

Basis for DNA ejection from single phage particles

...ed whether the energy thus stored is sufficient to permit phage DNA ejection, or only to initiate that process. The researchers used fluorescently labeled phage DNA to investigate in real time (and with a resolution time of 750 milliseconds) the dynamics of DNA ejection from single phages. The ejected DNA ...

UN votes to ban human cloning

...ecognize that other sovereign States might want to permit strictly controlled applications of therapeutic cloning. The Declaration was a non-binding political statement, which would not affect Britain's position on the issue. China felt the prohibitions in the text might be "misunderstood" as covering all ...

Nanoparticles offer new hope for detection and treatment

...emically," Lanza says. The nanoparticles also may permit more effective follow up, because a doctor could use them to discern whether a tumor was still growing after radiation or chemotherapy treatments. Although this study focused on melanoma tumors, the researchers believe the technology should work for...

Surprising findings reported about iron overload

...ekly removal of a pint of blood by phlebotomy ?can permit the progressive accumulation of iron deposits in target organs that may result in complications such as cirrhosis of the liver, liver cancer, arthritis, diabetes, impotence and heart failure. "The finding that Asians and Pacific Islanders have high ...

Bound for destruction: Ubiquitination protects against improper Notch signaling

.... Thiscompetition between two ubiquitin ligases to permit or suppressactivation of a signaling pathway represents a neat solution to theproblem confronting cells of how to prevent molecular loose cannonsfrom fouling their precisely ordered workplans....
