Ants Genetic Engineering Leads To Species Interdependency

Findings reported last week reveal how anevolutionary innovation involving the sharing of genes between two antspecies has given rise to a deep-seated dependency between them for thesurvival of both species populations.The new work illustrates how genetic exchange thr...

Papers of DNA Pioneer and Nobel Laureate Francis Crick Added to National Library of Medicine’s Profiles in Science Web Site

...thesis of proteins. In 1961, he and Sydney Brenner reported evidence that the genetic code is to be read three letters at a time, evidence that made possible the full elucidation of the code by 1966. Crick then turned to developmental biology, the study of how genes control the growth and specialization of or...

Deficiency of growth hormone and IGF-1 reduces cancer and kidney disease, but creates other problems

...artilage degeneration," Sonntag and his colleagues reported in an article in Endocrinology, published on-line today. But the hormones also increase cancer and other diseases that limit lifespan. The researchers developed a strain of dwarf rats that were naturally deficient in both growth hormone and in IGF-1...

New SARS Protein Linked To Important Cell Doorway

...look for potentially important viral proteins. As reported recently in the journal Structure, their efforts revealed orf7a, a SARS protein that makes its home in a structure cells use to modify proteins destined for transport to the cell surface. Researchers don't have any hard evidence of orf7a's function, ...

NYC's First Rapid HIV Drug-resistant AIDS Case Prompts Call to Step Up HIV Prevention

The individual then progressed to a diagnosis of highly drug-resistant AIDS by mid-January. Ordinarily, it has t...

NIAID Initiates Trial of Experimental Avian Flu Vaccine

...ses of and 46 deaths from H5N1 infection in humans reported to the World Health Organization. To date, there has been a small number of cases where human-to-human transmission of the virus may have occurred. However, public health experts fear that the virus may evolve into one that is more easily transmitted...

The Shapes Of Life: NIGMS Project Yields More Than 1,000 Protein Structures

...years of the pilot phase, the centers in aggregate reported 109, 217, and 348 structures, respectively. Now, halfway through the fifth year, they’ve surpassed a total of 1,000. Many of these structures are very different from previously known structures, said Norvell. The findings contribute to the initiativ...

New insight into people who 'see' colors in letters and numbers

...d. They chose those graphemes that the synesthetes reported elicited specific colors. They designed the experiment so that if the synesthetes really were seeing the colors, that color perception would help them distinguish shapes such as triangles or squares formed by the graphemes. In another experiment, the...

Newly Discovered Compound Blocks Known Cancer-Causing Protein

... new compound, called cysmethynil. Their finding, reported in the March 22, 2005, issue of Proceedings of the National Academy of Sciences, is the first step toward developing a new class of anti-cancer drugs that block the Icmt protein from activating uncontrolled cell growth, a hallmark of cancer, accordin...

Implanted Devices Detect High-Risk Heart Failure Patients

... suffer from the condition, with 400,000 new cases reported each year. Roughly one-half of patients die within five years of diagnosis. Although there is no cure, drugs can improve the strength of the heartbeat (digoxin), relax blood vessels (ACE inhibitors)or remove the excess buildup of fluid in the lungs ...

VCU Researchers Identify Networks Of Genes Responding To Alcohol In The Brain
