Fire ant-attacking fly spreading rapidly in Texas

...Texas. "It is rewarding to see the first species expanding over more than four million acres of Texas," says Gilbert, "but we've failed miserably in parts of Texas, like South Texas, to which these first phorids apparently cannot adapt. That's why we are focusing research efforts in parts of Argentina that l...

Iowa State researchers improving plastics made from corn and soy proteins

...s," he said. "We see biorenewables taking hold and expanding every day." Sam Senti, an application specialist for Vibroacoustics Solutions Inc., said the company would like to use biorenewable and biodegradable plastics in a stick lubricant it has developed. The bio-based lubricant rubs off on metals ?it, f...

Learning the language of DNA

... majority of genes in the mouse and human genomes, expanding the number of known promoters by five- to ten-fold," Professor Hume said. The findings of the consortium have also upended the traditional view that each gene has a single promoter and a single starting position. The team found that, while genes ...

Embryos exposed in 3-D

...application in the treatment and cure of a rapidly expanding list of diseases and injuries. Scientists believe cell-based therapies could be used to repair damaged heart muscle following a heart attack, replace skin for burn victims, restore movement after a spinal cord injury and regenerate pancreatic tissue...

New technology enables faster, more efficient cell harvest: Cell therapy meeting study

Expanding waistlines triggered by your genes

...n meshwork that holds fat cells in place and frees expanding fat cells, allowing their spread and expansion underneath the skin. The study illustrates a relationship between the gene and obesity and metabolism. The MT1-MMP gene is specifically important in regulation of fat cell size and metabolic gene expres...

Science captures the essence of fruit

...omb is confident they will also play a role in the expanding health food market. "Researchers are finding ever greater numbers of foods and food compounds that can enhance human heath and wellbeing. The trouble is, they don't always taste very good ?and until they do it will be difficult to encourage consume...

DOE JGI finishes 100th microbial genome

...ticularly productive vein to mine in exploring and expanding the frontier of microbiology. Especially where, through conventional culture methods, we are unable to shed light on the metabolic profiles of these microorganisms and their environmental implications, DNA sequencing provides us a welcome set of tool...

Viral genetic differences are possible key to HIV dementia

...s still exploratory: "We are now in the process of expanding this to a survey of 100 to 150 individuals." The study's co-authors were Sergei L. Kosakovsky Pond, PhD, of UC San Diego; Yang Liu, PhD, of Monogram Biosciences, South San Francisco; Benjamin M. Good, MS, of UCSD and VA San Diego Healthcare System;...

Creating a window on 'oceans in motion'

...a large, vivid new global window on marine life by expanding worldwide the work of two pioneering North America-based programs that follow the movements of important species using electronic tags. Convening at Dalhousie University, Halifax, the experts will announce a global collaboration, the Ocean Tracking ...

Marine 'dead zone' off Oregon is spreading

...s to have begun, scientists say, and apparently is expanding its scope beyond Oregon waters. This year for the first time, the effect of the low-oxygen zone is also being seen in coastal waters off Washington, researchers at OSU and the Olympic Coast National Marine Sanctuary indicate. There have been repo...

AIDS-related cognitive impairment exists in two separate forms

...udy analyzed prostatectomy samples, Epigenomics is expanding its research to see if the same results can be obtained from prostate biopsies. "If the test is a strong enough predictor of a good prognosis at the stage of biopsy, men with indolent cancer may not need surgery or radiation at all," she said. "We k...

Markers of gene, protein, or micro-RNA activity predict outcome in prostate and colorectal cancers

"If the test is a strong enough predictor of a good prognosis at the stage of biopsy, men with indolent cancer may not need surgery or radiation at all," she said. "We k...

Wisconsin scientists grow two new stem cell lines in animal cell-free culture

...e United States, researchers have been calling for expanding the number of lines approved for federal funding because existing lines have been shown to accumulate genetic mutations that, while not a serious impediment to scientific research, make the lines questionable for therapeutic use. What's more, some sc...

Salmonella bacteria use RNA to assess and adjust magnesium levels

...to sense and respond to a metal ion, substantially expanding the types of molecules that riboswitches can detect to help cells assess and react to their environment. First identified in 2002, riboswitches sense when a protein is needed and stop the creation of the protein if it isn't. That in itself isn't re...

New licensing agreement to maximize AIDS drug development

...SAID committed to improving reproductive health by expanding the contraceptive choices of women and men and by helping to prevent the transmission of HIV/AIDS and other sexually transmitted diseases.
