Protein discovery targets antibiotic-resistant bacteria

...r group is the first to solve the structure and to begin to understand the function of this particular protein,?says Dr. Nancy Martin (Microbiology & Immunology), who coordinated the study with Dr. Zongchao Jia (Biochemistry). “It turns out to be a potentially good target in a wide range of bacteria th...

New study may show how to forestall a fatal, virus-caused immune-system meltdown

...c fibrosis and so on ?we find that things suddenly begin to make sense,?said UTMB professor Norbert Herzog, one of the paper’s senior authors. “Cell signaling networks are like spider webs—pulling on one strand causes all the strands to move, and the Ingenuity system helped us see and comprehend connection...

Post oak grasshoppers emerging

... her lifetime. In the spring, when post oak leaves begin to emerge, the eggs hatch and the nymphs begin to climb trees to feed. They go through at least five developmental stages before becoming adults, a...

FSU researchers determine a critical factor in workings of proteins

...urther study," Zhou said. "For example, we now can begin to uncover the molecular bases of large variations in association rate among proteins. It also might be possible to design proteins with the desired association rate." Attila Szabo, chief of the Theoretical Biophysical Chemistry section of the Nat...

Cheaper, better disease treatments expected from faster approach to developing antibodies

...k those bacteria and grew large numbers of them to begin refining the steps needed for mass-scale production of promising therapeutic antibodies. ...

Molecular signature may identify cisplatin-sensitive breast tumors

... will be tested in a clinical trial anticipated to begin at the MGH Gillette Center for Breast Cancer and collaborating institutions later this spring. "This paper describes a specific molecular pathway that makes these tumors sensitive to a therapy infrequently used for breast cancer," says Leif Ellisen...

Birth rate, competition are major players in hominid extinctions

... "Why did they not start eating bunnies? They did begin fishing." Jablonski believes that competition from modern humans was already too strong. The environment was marginal and modern humans were already foraging and small-animal collecting. "I think they were out-competed at the very end," says ...

UF scientists discover new genus of frogmouth bird in Solomon Islands

...that frogmouths are an enigmatic group of birds to begin with. "That this should prove to be such a distinctive new genus, which it unquestionably is, has profound biogeographical implications and represents a real breakthrough in elucidating the evolutionary history of the family," Olson said. ...

Researchers discover genetic cause for word-finding disease

...ough no exact statistics are available. People can begin to show symptoms of PPA as early as in their 40's and 50's. Scientists discovered the gene mutation, called a progranulin gene mutation, in two unrelated families in which nearly all the siblings suffered from PPA. In the first family, three out o...

Scientists perform 'tricky' operation

...ific genes of interest to the whole chromosome and begin the mapping process. "Mapping the genome is the next step in the genome sequencing of T. vaginalis and will create a visual blueprint of the parasite, allowing researchers to see where their genes fit in to the big picture." The results of the...

Largest genomic search finds genes that may contribute to autism

...reen young children for autism at an early age and begin interventions earlier, which can have a dramatic effect for some children," Dawson said. A second phase of the Autism Genome Project also was announced today to continue the effort to discover the genes that cause the disorder. This $14.5 million...

Experimental vaccine given during pregnancy reduces stillbirths from common virus

...e viral DNA to the animal’s cells. The cells then begin manufacturing the viral protein. Cells of the guinea pigs?immune system detect the viral protein and launch an attack against it. In so doing, they learn to recognize CMV. The gene used in the experimental guinea pig CMV vaccine—UL83, also called ...

Meeting the ethanol challenge: Scientists use supercomputer to target cellulose bottleneck

...chain. This gives the enzyme a crucial foothold to begin the process of digesting or "unzipping" the cellulose into sugar molecules. To the scientists, the simulation is like a stop-motion film of a baseball pitcher throwing a curveball. In real-life the process occurs far too quickly to evaluate visua...

In presence of fragrant cleaning products, air purifiers that emit ozone can dirty the air

...ndoor air purifiers will be important as officials begin the process of regulating air purifiers that emit ozone. In September 2006, California Gov. Arnold Schwarzenegger signed into law Assembly Bill 2276, requiring the California Air Resources Board to develop regulations that will set emission standards...

Engineering the heart piece by piece

...and pH level. This can then encourage the cells to begin producing the kinds of molecules needed to signal to and connect with other cells, and to produce the extracellular matrix that supports cells in tissue. The U-M Artificial Heart Laboratory has teamed up with a commercial partner to develop a nov...

Light-based probe 'sees' early cancers in first tests on human tissue

...imaging technique," Wax said. His team plans to begin a small clinical trial of the advanced endoscope in collaboration with researchers at Duke University Medical Center. The team also is conducting animal studies to test the feasibility of incorporating fa/LCI into instruments for examining the colon,...

New science of metagenomics 'will transform modern microbiology'
