Microbes under Greenland Ice may be preview of what scientists find under Mars' surface

...of Greenland's two-mile thick ice sheet could help guide scientists searching for similar bacterial life on Mars. Methane is a greenhouse gas present in the atmospheres of both Earth and Mars. If a class of ancient microbes called Archaea are the source of Mars' methane, as some scientists have proposed, ...

Children overprescribed antibiotics for sore throat

...objective criteria in the form of GABHS testing to guide the antibiotic treatment of children with sore throat. Limiting antibiotic prescribing to children with a positive GABHS test result is a feasible goal for primary care physicians and an important step toward judicious use of antibiotics overall," th...

... itself. These patent 'landscapes' will be used to guide the development of improved technology toolkits in a new, inclusive manner. Says Richard Jefferson, CAMBIA's CEO, "It's not so much about getting access to old patented technology ?it's about forging collaborations to develop better, more powerful t...

Poison + water = hydrogen. New microbial genome shows how

...es found there. "What we want to have is a field guide for these microbes, like those available for birds and mammals," Eisen says. "Right now, we can't even answer simple questions. Do similar hot springs, a world apart, share similar microbes? How do microbes move between hot springs? Our new work will...

Web model of influenza-host lifecycles will aid scientists in creating anti-viral drugs

...n the influenza virus and its human host will help guide researchers in creating new anti-viral drugs, say researchers at UT Southwestern Medical Center. The on-line map, part of a project called Reactome, is intended to teach scientists about parts of the influenza lifecycle they might not be familiar w...

Common molecular 'signature' identified in solid tumors

...rowing the list of the most active ones provides a guide to directing future research. "We know that there are hundreds of miRNAs, and some of them may have multiple gene targets. Finding the ones that appear over and over again in various forms of cancer will help us design new and better interventions,...

...orward." The 3D ultrasound probes also might help guide physicians during cardiac ablation therapy, he added. In such procedures, cardiologists use catheters to burn specific locations on the surface of the heart in patients with atrial fibrillation, a disorder characterized by an abnormal heart rhythm. ...

Rice bioengineers pioneer techniques for knee repair

...tes or hydrogels called scaffolds that are used to guide colonies of donor cells. Donor cells can be either adult stem cells or other immature cells. Athanasiou's latest work was done using chondrocytes, or cartilage cells. Athanasiou, a former president of the international Biomedical Engineering Society...

Researchers reverse juvenile diabetes in animal model

... doses of insulin to the dendritic cells will help guide the dendritic cells directly to the T cells. Adding the insulin ensures the dendritic cells are used specifically to block the T cell destruction of the beta cells, and not otherwise interrupt a person's immunity. In other words, the dendritic cells ...

CU, USDA team to curb two invasive, poisonous vines

... require federal approval. "Our research will help guide the selection of an effective agent." Milbrath, whose funding from USDA supports the Cornell collaboration on a three-year project, is working with researchers at a USDA facility in Montpellier, France, and other colleagues who are working in Ukrain...

Researchers use dirt to stay one step ahead of antibiotic resistance

...predict future clinical emergence, but it can also guide the development of therapies to counteract this resistance." Researchers screened 480 strains of soil bacteria isolated from diverse locations for resistance to 21 clinically relevant antibiotics. At high drug concentrations, the soil-dwelling bact...

When mice choose mates, experience counts

...elp scientists understand the brain chemicals that guide mate selection, Pfaff and his colleagues exposed female mice to odors of either a male mouse alone or a male mouse with a female. The females consistently preferred the scent of males linked to other females. "Our data suggest that female mice may u...

Researchers develop portable 'vein finder' for faster, more accurate injections

...box holds a reflector and needle guide. The needle guide is positioned parallel to the sound beam being transmitted by a transducer in the device's reusable section. As medics move the device along a patient's arm or leg, the transducer emits a thin acoustical beam, about the size of pencil lead, into ...

Chemical guidance of T cells leads to immunologic memory and long-term immunity

...ecifically, two molecules known as chemokines help guide them toward the cells that release these activation signals. "Understanding the processes whereby CD8+ T cells find their way in the lymph nodes is important because their activation is essential for eliminating infected cells and for providing, to...

Molecule does more than slice and dice RNA

... assimilated into large multiprotein complexes and guide those molecules to destinations in the cell where they turn off genes. "The size of these small RNAs is a determinant of their function," Hannon explained. "If the RNAs are too big or too small, they don't make it into the effector complexes." Thro...
