Funding and bureaucracy, not access to journals, are chief obstacles to scientific productivity

... improved research productivity but they have also helped to maximize return on investment in scientific research." A number of recommendations to address the non-financial barriers to productivity were highlighted in the study including help with recruiting suitable research and administrative staff, aut...

Methane-belching bugs inspire a new theory of the origin of life on Earth

... sediment beneath kelp beds, he and his group have helped to break this impasse. Life may have emerged in just such an environment, and this microbe's unique biochemistry may harbor the molecular fossil of the first metabolism on Earth. While other microbes make methane from carbon monoxide, this particula...

Parallel evolution: Proteins do it, too

...duplication of a gene encoding a pancreatic enzyme helped Asian colobine monkeys cope with an unusual diet. "Colobines are different from other monkeys in that they primarily eat leaves rather than fruit or insects, and leaves are very difficult to digest," Zhang said. The monkeys manage with a digestive ...

UCLA study finds same genes act differently in males and females

...inesswomen interested in advancing women's health, helped fund the study. "Many of the genes we identified relate to processes that influence common diseases," said Yang. "This is crucial, because once we understand the gender gap in these disease mechanisms, we can create new strategies for designing an...

Major initiative proposed to address amphibian crisis

...y and one of the pioneers in this field, who first helped document amphibian declines almost 20 years ago. "These are bioindicators that something is wrong with the planet," he said. "But amphibians play a major role in many ecosystems, in some places the amphibian biomass is greater than that of all the...

All the eggs in one basket

...rvation efforts since the 1970's have dramatically helped increase green and hawksbill turtle populations that nest on protected beaches. However, they argue that dwindling turtle populations on many historically important nesting beaches are overlooked by conservation assessments that focus instead on the...

Race to halt global amphibian crisis boosted by rediscovery of endangered Colombian frogs

...rnational (CI) and American Bird Conservancy (ABC) helped Fundación ProAves of Colombia purchase the 1,600-acre site to protect it as a nature reserve. Neither of the rediscovered frog species had the deadly fungal disease chytridiomycosis, raising hopes that the species can be saved in the new protected a...

Researchers find protein that silences genes

...D., Washington University professor of chemistry, helped define the precise locations of the acetyl groups that HDA6 can remove, down to which acetylated amino acids are involved. "The bottom line is that HDA6 has very broad specificity. It can remove the acetyl groups from multiple histones and from mu...

Acid rain causing decline in sugar maples, say researchers

... rain. Though pollution-control legislation has helped reduce sulphuric acid by one-third since its high point in the 1960s, nitric acid from automobiles has not significantly declined. This research was supported by the National Science Foundation and the Hubbard Brook Ecosystem Study. ##...

Gene therapy prevents the onset of diabetic symptoms in mice

Test reveals effectiveness of potential Huntington's disease drugs

...sion of Huntington's in people, while riluzole has helped relieve some symptoms. "Our results provide the first systematic comparison of various clinically relevant glutamate pathway inhibitors for HD treatment and indicate that memantine holds the most promise based on its in vitro efficacy," Dr. Bezpr...

Trotting with emus to walk with dinosaurs

...dation. Among the emu revelations was one that helped resolve a mysterious "crossing over" track pattern seen at Red Gulch. Researchers had found that sometimes a dinosaur's tracks became crossed ?that is, the left foot crossing over the right and the right crossing over the left. That seemed pretty str...

UGA scientists unravel 'molecular inch-worm' structure of walking-pneumonia bacterium

...in-the-dark proteins and microcinematography, have helped unravel the development and function of a complex organelle in the bacterium that causes "walking pneumonia." The researchers have described in new, precise detail the unique cell extension that forms on one end of the bacterium Mycoplasma pneumonia...

New path from estrogen to survival in breast cancer cells described

...west mechanisms is dubbed "NEDDylation," which Yeh helped to find 10 years ago. This process requires multiple enzymes to attach NEDD8 to other proteins. To find proteins that can be altered by NEDD8, the four-member research team used yeast as their experimental platform, and SENP8 as a tool. This enzy...

International team analyzes human genetic variation in key immune region

...arly origins and the evolutionary forces that have helped to shape it over time. The findings also suggest that analyzing select SNPs within the HLA genes may offer a more economical alternative for characterizing the most common genetic variants in the region than standard HLA typing methods. Nearly thr...

Dinosaurs -- stones did not help with digestion

...ently many researchers have assumed that they were helped by stones which they swallowed. In their muscular stomach these then acted as a kind of 'gastric mill'. But this assumption does not seem to be correct, as scientists at the universities of Bonn and Tübingen have now proved. Their research findings c...

New technology used to construct the first map of structural variation in the human genome

...entified CNVs in the human genome. "This method helped us to develop the first comprehensive map of structural variation in the human genome," says Dr. Nigel Carter, one of the lead investigators on the project. "We used it to help identify 1,447 CNVs, which covered 12% of the human genome." The othe...

History-hunting geneticists can still follow familiar trail

"The study of mtDNA has helped to demonstrate the African origin of our species and the relationship between living humans and the Neanderthals," said Connie Mulligan, an associate professor of anthropology in the College of Liberal Arts and Sciences and an assistant director of t...

"This work represents a hallmark in the genomic and bioinformatic characterization of lactic acid bacteria that have an impact o...

High HPV concentrations combined with smoking significantly raise risks of cervical cancer
