Finding hidden invaders in a Hawaiian rain forest

...ind in dense, wet forest in Hawaii. This study has helped us with a particularly difficult-to-map species with confusing signatures, Myrica faya. This is the first time in my experience that remote sensing has detected an understory species, kahili ginger, one of the most disruptive weeds in Hawaiian rain f...

DOE JGI launches IMG public online microbial genome data clearinghouse

...AP manages the IMG's data content and curation and helped develop the system, with additional support provided by DOE JGI's Microbial Ecology and Genome Data System groups. "The IMG system champions the principle of integration in an evolutionary context" said Kyrpides. "This is critical for enabling the ge...

Researchers test new therapy for advanced melanoma

...ofessor of medical microbiology and immunology who helped develop the technology used in the study. Electroporation is a technique in which a hand-held device applied to the skin delivers pulses of electricity to open up pores in the tumor cell membrane. This opening allows a small therapeutic molecule -- ...

Researchers pioneer new gene therapy technique using natural repair process

...researcher from UT Southwestern Medical Center has helped establish a method of gene therapy that can accurately and permanently correct mutations in disease-causing genes. The findings are available online in Nature. By artificially initiating a DNA repair process known as homologous recombination, Dr. M...

Beneficial Beetles Battle Pesky Saltcedar

...nd that a leafbeetle that they've investigated and helped import, Diorhabda elongata, has now defoliated hundreds of acres of saltcedar-infested test sites in Colorado, Nevada, Utah and Wyoming. Yet the beetle poses no hazard to people, pets or crops. DeLoach is with the ARS Grassland Protection Research U...

Genome study of beneficial microbe may help boost plant health

...osted online on June 26. "The genome sequence has helped us identify new chemical pathways that the microbe apparently uses to create what are known as 'secondary metabolites' ?possibly including new antibiotic compounds," says Ian Paulsen. He led the sequencing at The Institute for Genomic Research (TIGR)...

Researchers extend mouse lifespan by protecting against free radicals

... heart muscle tissue, indicating that the catalase helped protect from age-related heart problems seen in wild-type mice. The MCAT mitochondria also had fewer mutations, and the MCAT nuclear DNA had fewer oxidized components. "This study is very supportive of the free-radical theory of aging," said Rabinov...

International Team Determines Geographic Origin of Leprosy

...seases. Aggressive therapy with multiple drugs has helped drive down the number of registered leprosy cases around the world, notes Dr. Sizemore. However, despite drug treatment, the number of new cases of leprosy detected each year has stayed the same or risen. The new understanding of the genetic makeup o...

Assessing the Amazon River's sensitivity to deforestation

...ing us simulate the entire river through time, has helped us learn much about how the river flow and flooded area react to year-to-year variations in climate." Currently entering a third phase of study, a model of the Amazon River and floodplain will be combined with estimates of future deforestation to un...

Unexpected lock and key mechanism found for the assembly of tumor blood vessels

...pressed tumor growth, indicating that the integrin helped in the creation of tumors "Our study marks the first time this integrin was found to play a key role in angiogenesis," said Varner. "This integrin is known to regulate the body's inflammation response, but until this study it wasn't suspected of reg...

Identification of specific genes predicts which patients will respond to Hepatitis C treatment

...he support of my friends and hospital staff really helped me through the treatment. And I wanted to participate in this study so that the research could help others in the future." The study followed 31 patients with chronic Hepatitis C who were treated at Toronto Western Hospital from October 2001 until M...

Gifts from the sea

...s large nerve cell fiber, called a giant axon, has helped neuroscientists understand basic nervous system functions. MBL scientists studying squid have learned how electrical signals are transmitted from cell to cell, how nutrients and other important particles are transferred from cell to cell, and how cer...

Compound might defeat African sleeping sickness, clinical trial beginning this month

... carefully monitoring the trials," said Olson, who helped design and will oversee the study. She is an infectious disease expert who retired after a long career with Abbott Laboratories. "We're trying to improve the lives of these patients by treating the disease early on in the local villages before it pr...

OHSU research shows vitamin C counteracts some negative impacts of smoking on unborn babies

...lungs. While past research in the Spindel lab has helped define how nicotine causes these changes, many of the specific mechanisms for infant lung development problems remain unknown. However, previous research has clearly shown that infants born to smoking mothers often suffer from reduced lung air flow. ...

Scientists focus on 'dwarf eye'

...rg School of Public Health study in the 1970s that helped define the disease as genetic. In Sundin's study, the researchers examined the woman's DNA for possible gene mutations causing nanophthalmos. According to Sundin, MFRP was a surprise candidate. "Mutant MFRP was recently identified in mice as a c...

Biased reporting found in cancer prognostic studies

...ding only a sample. Both of these details may have helped to fabricate the strong prognostic factor/cancer association in these studies, according to the authors. "These biases may create a spurious knowledge base of cancer predictors that may be of no use and may be potentially harmful," conclude the auth...

Scientists show that tick-borne flaviviruses use a novel mechanism to evade host defenses

...ork, Dr. Bloom says, scientists knew only that NS5 helped tick-borne flaviviruses replicate. RML's Sonja Best, Ph.D., who spearheaded the Langat virus work, says the group will continue to study tick-borne flaviviruses by examining the role and location of NS5 in Powassan virus. Powassan virus, found in No...
