Tufts-NEMC researchers identify enzyme that activates cancer cell growth and invasion

...blocking the MMP-1/PAR1 pathway with the pepducins described in our study could provide a novel therapeutic approach for treating invasive cancers and possibly other tissue remodeling processes such as inflammation and atherosclerosis," said Kuliopulos....

Ingestion of afterbirth appears to promote maternal behavior in mammals

... toward the young. "This activation is best described by focusing on two sites in the brain where it takes place," he says. "Increased opioid activity in the ventral tegmental area, a motivation area of the brain, facilitates the onset of maternal behavior. Increased opioid activity in the media...

Findings suggests that blocking estrogen may be crucial to lung cancer survival

.... "Evidence from our study confirms what has been described for breast cancer that blocking the estrogen receptor and the epidermal growth factor receptor pathways together is more effective," said Dr. Stabile. In the second study, Pamela Hershberger, Ph.D., assistant professor in the department of pharmaco...

...emperature, or electric potential. The experiments described in the PNAS study use a polymeric liquid that freezes quickly and can then be scanned directly with the tip of an atomic force microsope. However, the same morphology diagram should also apply to other liquids and other substrate materials. It should...

X-rays have become laser-like

...parallel to the incident laser. The phenomenon described above is not new. It has become a standard technique for routinely producing laser-like extreme ultraviolet radiation at wavelengths down to the 10 nanometer regime. Pushing the frontier of this technology to ever shorter wavelengths has proven ever ...

Mechanical tension helps shape lung development

... the turn of the last century, scientists commonly described biological phenomena in terms of mechanics. "The early developmental biologists watched embryos developing, and saw it as a mechanical process," Ingber says. This appreciation of mechanics and form fell away as the 20th century progressed. With the...

Teams build robots that walk like humans

...adapt to the terrain as it walks. The work, to be described in the Feb. 18 issue of the journal Science , could change the way humanoid robots are designed and controlled and has potential applications for robotic prostheses. It could also aid scientists' understanding of the human motor system. Developed at...

Robots walk with close-to-human efficiency

...unpowered and powered robots. For the robots being described in Science , the researchers at all three institutions have simply substituted small motors for gravity power. Ruina says the research followed the example of the Wright Brothers, who carefully researched gliders, then simply added a motor to achie...

The secret lives of whales

...g lawn of grass. While the first zombie worms were described only a few months ago from one whale skeleton off California, Craig and co-workers have just found another species off Sweden and now think these zombie worms may occur worldwide. Because of their ability to break down lipids in cold water, these an...

Coastal dead zones may lead to ecosystem-based fisheries management

...me most available oxygen in bottom layers. Crowder described how fish and shrimp can evade death simply by relocating to the zone's edge. "Basically, it's the same as the way forest wildlife might aggregate on the edge of a forest fire," Crowder said in an interview. And shrimpers and fishermen exploit that kn...

Muon opportunists: Detecting the unseen with natural probes

...heir charge makes them easy to track. Researchers described several promising uses for muon radiography, as it is called, at the annual meeting of the American Association for the Advancement of Science (AAAS). Arturo Menchaca-Rocha, director of the physics institute at the National Autonomous University of ...

Rapid, new test develped for inherited immune deficiency

...ce," she said. The development of the new test is described in the February issue of The Journal of Allergy and Clinical Immunology. Although the availability of the test raises the question of whether states should begin using it on all newborns, Dr. Puck concluded that the new test is not quite ready for wi...

Antibody that neutralizes most HIV strains described by scientists at The Scripps Research Institute

...es. The structure of one of these, called 4E10, is described in the latest issue of the journal Immunity. "This antibody is very broadly active," says Scripps Research Professor Dennis Burton, Ph.D., who led the research with Scripps Research Professor Ian Wilson, D.Phil. "It neutralized nearly 100 differ...

Elusive HIV shape change revealed; Key clue to how virus infects cells

... ago by another group. Harrison and Chen have now described gp120's structure before the shape change, yielding vital before-and-after information on how the molecule rearranges itself when it encounters the CD4 receptor. "Knowing how gp120 changes shape is a new route to inhibiting HIV by using compound...

The patent is assigned to VTIP and the Mayo Foundation for Medical Education and Research. "Pharmaceutical Preparations of Bioactiv...

First ever estimate of cod fishery in 1850s reveals 96% decline on Scotian Shelf

...fishing. To date, declines have only been vaguely described for predatory fish species and complex coral reef systems around the world. To estimate long ago fish levels, researchers used 1850s New England schooner records of daily catch locations and fleet activity on the fishing grounds. Fishers then, using...

Bugs, even 'bad' ones, can be educationally beneficial, new book says

Waldbauer uses examples from history, his career and conversations with his entomologist colleagues to illustrate what we ca...
