Small, self-controlled planes combine plant pathology and engineering

...Schmale and his colleagues collected more than 500 viable colonies of Fusarium, representing at least a dozen species. “For 11 of these Fusarium species, this is the first report of their ability to be transported great distances above the surface of the earth,” Schmale said. “Our work has important impl...

Plastic that grows on trees

...s most abundant sugar. “But getting a commercially viable yield of HMF from glucose has been very challenging,” Zhang said. “In addition to low yield until now, we always generate many different byproducts,” including levulinic acid, making product purification expensive and uncompetitive with petroleum-bas...

Staphylococcus aureus hides out in cells

...sult of antibiotic treatment, the team still found viable bacteria in their model system two weeks after infection. The findings may help in understanding persistent infections, and in designing new antibacterial drugs. S. aureus has not traditionally been considered an intracellular pathogen, but the m...

Sandia researchers take new approach to studying how cells respond to pathogens

...crofluidic modules -- one for trapping and imaging viable cells during stimulation with pathogens. The other combines cell preparation steps, cell selection and sorting followed by analysis of protein content in the selected cell subpopulations. "In effect, we are taking many work-horse technologies such...

The sturdier sex? -- Study by Pittsburgh scientists finds female stem cells work better

...act on the successful development of stem cells as viable therapies for a variety of diseases and conditions, according to the study’s senior author, Johnny Huard, PhD, director of the Stem Cell Research Center at Children’s and the Henry J. Mankin Professor and Vice Chair for Research in the Department of ...

OHSU surgeon implants donated tissue allografts

...for up to 28 days in a medium that keeps the cells viable and the tissue healthy so it continues to live after transplantation. Cooperation between Community Tissue Services, which has been serving Portland and the greater Oregon community for decades, and the tissue preparation and coordination resourc...

Mimicking how the brain recognizes street scenes

...n intriguing idea or technology and a commercially viable concept. Recognizing Scenes The IEEE paper describes how the team "showed" the model randomly selected images so that it could "learn" to identify commonly occurring features in real-word objects, such as trees, cars, and people. In so-called...

ConocoPhillips establishes $22.5M biofuels research program at Iowa State

...search programs with major universities to produce viable solutions to diversify America's energy sources. ConocoPhillips will make an initial $1.5 million grant in 2007 to support Iowa State researchers, with additional grants of $3 million per year for seven years. Biorenewable fuels are produced fr...

Antibody therapy prevents type 1 diabetes in mice

..., this therapy, if given early enough, may offer a viable method for preventing the onset of type 1 diabetes in genetically at-risk people. "Our studies and others suggest that CD137 plays a significant role in the development of and genetic predisposition to type 1 diabetes. In this study, for the first ...

Dual gene therapy suppresses lung cancer in preclinical test

...showed that the gene combination cut the number of viable cells in four lines of human non-small cell lung cancer by 70 to 80 percent 48 hours after treatment while leaving a control group of normal cells unaffected. The cancer cell lines treated with the gene combination had 2 to 3 times more cells killed ...

Penn study on lung-infecting bacterial enzyme suggests new approach to cystic fibrosis treatment

...tic treatments and supportive measures, might be a viable near-term approach to improving length and quality of life for many CF patients, before CF gene therapy becomes a reality. The Penn research team demonstrated the disruptive action of SMase in frog oocytes (egg cells) engineered to place CFTR in t...

Researchers discover new details about HIV-1 entry and infection

...a of women infected with HIV-1 while LC may harbor viable virus for some time before spreading it to other cells. These results reveal that it is necessary to consider mechanisms of viral entry into both CD4+ T and LC when searching for an effective way to interfere with infection through the vaginal epi...

Swell gel could bring relief to back pain sufferers

...by our findings, much work lies ahead to develop a viable non-surgical repair technology to replace spinal fusion as the standard surgical treatment for chronic lower back pain." He added that future work will investigate biodegradable microgels that release additives to stimulate regeneration of interve...

Penn researchers replace organ in adult mice using 'single-parent' stem cells

McLaughlin and his colleagues report their findings in the Feb. 15 issue of the journal Genes & Development. "While previous rese...

Ultrathin films deliver DNA as possible gene therapy tool

...ntists' imaginations for decades, but is not yet a viable therapeutic method. One sizeable hurdle is getting the right genes into the right place at the right time. Engineers at the University of Wisconsin-Madison are now developing a tool to tackle this problem. David M. Lynn and his colleagues have cre...

'Exercise pill' switches on gene that tells cells to burn fat

...oncept that metabolic engineering is a potentially viable approach, it offers no help to an adult whose muscles are already formed and who now would benefit greatly from having more active, fat-burning muscles. That is why the potential of chemical metabolic engineering - possibly a one-a-day pill as o...
