Affymetrix and the Karolinska Institutet Announce Translational Medicine Strategic Alliance

...icine Initiative. 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 microar...

Unprecedented water level rise in Somalia

...ll as electric power lines. The destruction of the bridge limits the accessibility and mobility of the population around the city, affecting daily activities such as commuting to work, school and accessing hospitals and markets. The floods affected at least 170 households. ...

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

...ht eventually create 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, transmissi...

Computational Method Speeds Mapping of Cell Signaling Networks

...naling networks at once. This new work should help bridge that gap. Human T-cells--the system Nolan and Lauffenburger's team used to validate their technique--rely on a complex signaling network to protect the body from pathogens such as viruses. When a T-cell encounters a foreign invader, it relays a dang...

New World founders small in number

...cendants of archaic humans crossed the Bering land bridge from Siberia to North America. Several lines of evidence support this model, but that's where the consensus ends and the details are hotly debated. In a paper published in the premier open-access journal PLoS Biology, Jody Hey now reveals how the siz...

Pair of cancer genes found to drive both cell migration and division

...esearchers also hope their findings will provide a bridge between two scientific fields that have traditionally kept to themselves. "Scientists studying cell migration have focused on the front of the cell and what drives it, while cell division researchers have concentrated on the furrow within the dividi...

Critical step traced in anthrax infection

...est the potency of the anthrax toxin. "We tried to bridge reductionist science with the in vivo situation ?we have to do both to make correlations," he said. The researchers, who were funded by the National Institutes of Health and the National Science Foundation, will continue to study protein unfolding i...

By creating molecular bridge, scientists change function of a protein

...functions," Zhao said. "Our approach is to build a bridge between the existing protein function to the target new function by adding some intermediate functions followed by stepwise directed evolution of these intermediate functions. If done, it gives you the ability to create protein functions for any purp...

Wild grasses and man-made wheats advance research capabilities

...type of greenbug or rust in wheat may require some bridge building. Dr. Jackie Rudd, associate professor at...-made hexaploid wheats, provides a more accessible bridge to the wild species, he said. Most synthetic hexaploid wheats are crosses between Durum (pasta-type...

Wild Gorillas Handy with a Stick

...n front of her, and, walking upright, used it as a bridge to cross the muck. That tool use was seen in lowland gorillas and not mountain gorillas—the most intensively studied gorillas—may reflect the different ecological challenges facing the two populations, supporting the notion that ecology influences t...

Implantable pumps extend lives of patients too sick for transplant

...ot of data on the device when it was being used as bridge to transplantation," he continued. "We knew it could go for extended periods without problems, and that was the most compelling argument to use for implanting the device in patients who have no other options." For the trial, researchers enrolled 55 ...

Sahara's edge studied from ground, air and space to improve water management

...p a technical, human and institutional capacity to bridge Africa's water information gap using satellite data. ESA launched TIGER in 2002, as a response to that year's World Summit on Sustainable Development (WSSD) in Johannesburg, which stressed the potential of space-based systems to help achieve sustai...

Researchers make long DNA 'wires' for future medical and electronic devices

... of DNA solution," Guan said. Computer chips that bridge the gap between the electronic and the biological could make detection of certain chemicals easier, and speed disease diagnosis. But first, researchers must develop technologies to mass produce DNA circuits as they produce chip circuits today. The t...

New methods offer insight into regulatory DNA

...ual people and individual disease. The HapMap is a bridge from sequence data to the differences in individuals." The project focused on three regions of the human genome. The first, called the ENCODE regions, and about 30 million base-pairs of DNA, are being intensively studied around the world as a group...

Ancient humans brought bottle gourds to the Americas from Asia

...Asia in boats or who walked across an ancient land bridge between the continents, or that the gourds floated across the Bering Strait after being transported by humans from their native Africa to far northeastern Asia. "This finding paints a new picture of the founding of the Americas," says co-author Bruc...

New maps reveal true extent of human footprint on Earth

..." says Jonathan Foley, director of SAGE. To help bridge that gap, SAGE researchers are working towards a new "Earth Collaboratory," an unprecedented Internet-based data bank that would simultaneously draw on the knowledge of global scientists, local environmentalists and everyday citizens. Adds Foley: "[T...

Front-line immune cells mature in four stages, study shows

...is a stem-cell marker, so that told us there was a bridge between stem cells and NK cells." Once we discovered where to look (in lymph tissue), it was just a matter of careful, diligent work." The researchers also isolated cells of each stage and showed that under the proper conditions, stage-1 progenitor...

Cincinnati surgeons report new treatment for often-fatal injury

.... Giglia explains, but they are too short to fully bridge the damaged area in the chest. "Used alone, extender cuffs are hard to align and often slip into the defect to cause further complications," says Dr. Giglia. "Using a fixed stent provides an easy-to-see 'scaffolding' that can guide the surgeon to m...

Ancient global warming drove early primates' dispersal

...North America and traveled across a temporary land bridge connecting Siberia and Alaska. A third hypothesis is that primates had their origins in Africa or Asia and traveled through North America to reach western Europe. Finally, it has been suggested that the group originated in Asia and fanned out eastwar...

How plants avoid feeling the burn

... fast the electrons traveled across the carotenoid bridge between the electrodes. By measuring carotenoids of different chemical lengths, the team showed that the travel rate was fast enough to match or exceed measurements performed in the plant system. One of the greatest challenges of the experiment came...
