W.M. Keck Foundation funds study of friendly microbes

...hers at the School of Medicine will help fill this gap by funding a study to develop new approaches for isolating, sequencing and analyzing the genomes of "friendly" bacteria that inhabit the intestine and identifying the natural metabolic products that they synthesize in their native gut habitats. The ...

...nd gonadal tumor development. Thispericentromeric gap was one of the few holes remaining in the"finished" sequence of the human genome reported last October by theInternational Human Genome Sequencing Consortium. This "finished"sequence was the culmination of a 13-year effort to elucidate the orderand o...

Affymetrix and the Karolinska Institutet Announce Translational Medicine Strategic Alliance

...ative. The goal of the initiative is to bridge the gap between clinical research and application of genomics in patient care by bringing together leading clinical research institutes with advanced Affymetrix microarray technology. Karolinska Institutet will have access to a number of new microarray tech...

Fibril Shape Is The Basis Of Prion Strains And Cross-species Prion Infection

...prion fibril strains that can bridge the infection gap between previously separate animals like humans and elk and deer, which suffer from a prion disease called chronic wasting disease. Surewicz stresses, however, prion infection between species is still rare. "Fortunately, transmission by eating is ve...

An (ecological) origin of species for tropical reef fish

... Amazon North to Trinidad and Tabago. This 2000 km gap is believed to be a strong barrier for corals and associated reef organisms." "My idea was to test whether or not wrasses in the genus Halichoeres were genetically different North and South of this barrier. Since all of these species have similar ab...

Survey reveals women and doctors aren't talking about HPV

...help prevent cervical cancer. "The communications gap between providers and patients related to cervical cancer and HPV is an issue that is largely due to time constraints, and a reluctance to discuss a sexually transmitted infection with women," said Dr. Beth Jordan, medical director at ARHP. "But beca...

New Vaccine To Be Used For First Time In Polio Outbreak Response

...nt of the mOPV1 vaccine. However, a global funding gap of US$ 50 million must urgently be filled by July, to finance continued intensification of immunization campaigns in the second half of the year. Global eradication efforts have reduced the number of polio cases from 350 000 annually in 1988 to 1267...

Gap-climbing fruit flies reveal components of goal-driven behaviors

...s forced to decide whether to attempt to cross the gap "by foot." The researchers found that the flies first visually measure the gap width and then only cross the gap if it is a traversable width. If the chasm is short, flies engage ...

Beetle-inspired switch uses water for bonding

...ts, Steen said. "This new technology bridges the gap between scales as large as our hands and nanoscales," said Steen. "We need devices that allow us to communicate between the two scales." Co-authors include Michael Vogel, a postdoctoral researcher in Cornell's Department of Chemical and Biomolecul...

Cultural norms not unique to human societies

... two-action methodology. This approach bridges the gap between two conventional research methods: population-level observations on wild apes and one-to-one social learning experiments. In the study, researchers introduced a naturalistic foraging task into three groups (two experimental and one control) ...

Can two killers make a cure?

...He is preparing the results for publication. "The gap between monkeys and humans is much smaller than from mice to monkeys," says Ray Pickles, a gene therapy researcher at the University of North Carolina, Chapel Hill. "This could be in human trials pretty soon." Kobinger now plans a more extensive mon...

Unweaving amyloid fibers to solve prion puzzles

...e with mad cows and humans.," says Lindquist. That gap has also been observed between other species, she notes: "In fact, some type of prions from infected hamsters can't make the species jump into mice, while others do, and vice versa." While the results of this research are clearly of interest to scie...

Progress on HIV/AIDS significant but insufficient

...DS (UNAIDS) Executive Director Peter Piot said the gap between need and action remained enormously wide. Unless AIDS was controlled, the epidemic would expand for decades, killing large numbers and wrecking entire societies. The global response required that several milestones be met: world leaders shoul...

Retina adapts to seek the unexpected, ignore the commonplace

Because this adaptation occurred in both salamanders and rabbits, Meister concluded that it typifies retinal function in both amphibians and mammals, animals that differ grea...

Ancient anthropoid origins discovered in Africa

... to Seiffert, the latest findings help fill in the gap between later anthropoids and the oldest undisputed anthropoid, called Algeripithecus, found in Algeria, which lived around 45 million years ago. That species had been characterized by only a few teeth, which precluded significant insight into the sp...
