Achilles heel of the herpes virus possibly found

...s been hindered by the fact that the virus is very good at entering so many kinds of cells. The many possibilities for virus binding to cells make deciphering the entry process a difficult problem to solve. The gene that encodes B5 had in fact been sequenced, but not characterized, as part of the Human G...

Study shows humans have ability to track odors, much like bloodhounds

...y and that, with practice, you could become really good at it." In future experiments, UC Berkeley biophysics graduate student Jess Porter and Sobel plan to train volunteers to track odors in the field and test the limits of odor localization in humans. Porter, Sobel and their colleagues reported the re...

Scripps research scientists identify infertility molecule

...the mechanisms involving these proteins might make good targets for therapeutic intervention, perhaps even leading to new treatments and successful pregnancies for some of the more than 6 million American women affected by infertility. Fertility and the Demographics of the Western World In the Western w...

Researcher gets NSF grant to create mutant maize lines

...ble to obtain the seeds for their experiments. "A good chunk of this project is developing a community resource," Brutnell says. By providing these lines to the community, researchers with a wide range of interests and goals will have access to genetically unique seeds. For instance, researchers could us...

Scripps research scientists solve structure of a critical innate immune system protein

...s that make it harder, but not impossible, to form good crystals. A number of leucine-rich repeat proteins have been determined, but never one with this many leucine-rich repeats or so many carbohydrates. ### The article, "Crystal structure of human Toll-like receptor 3 (TLR3) ectodomain" is authored by...

Newly discovered genetic disease sheds light on body's water balance

...nism was disrupting fluid homeostasis. "This is a good example of the value of humility about what we know and don't know in clinical medicine," said Gitelman. "When something seems to fit a classic pattern, but actually doesn't, our job as physician scientists is to recognize the discrepancy and get to ...

Purdue scientists may have found key to halting spinal cord damage

...e root of some health problems. "Antioxidants are good scavengers of free radicals, and it's certainly wise to have plenty of them circulating in your bloodstream," he said. "The trouble is that when free radicals start attacking tissue, it happens in a tiny fraction of a second, after which they are gon...

Scientists turn tobacco against cancer

...?he says. “The antibody produced in tobacco is as good as the antibody produced in animal cells,?says Dr. Koprowski, noting that tobacco-derived antibody should be safer and less expensive to produce. The Jefferson scientists are seeking industry partners to begin mass production of the antibody. The ne...

Improving the potential of cancer vaccines

... specific antibody. "But you may also deplete the good cells needed for fighting cancer," said Wang. He and his group identified particular ligands (a special stretch of guanosine-containing DNA material) that can bind specifically to a particular receptor called human Toll-like receptor 8 and then turn...

Other laboratories have shown that notch plays a key role during human development in forming blood vessels. O...

Fundamental discovery -- Bone fracture

...problem and a lot of work has been done to develop good diagnostics. The leading diagnostic is bone mineral density." Measuring bone mineral density is valuable because it reveals how much bone a person has left. The amount of an individual's bone mineral density peaks around age 30, then decreases for t...

Structures of marine toxins provide insight into their effectiveness as cancer drugs

...er to chemically synthesize a better drug, it is a good idea to know how the natural compound works," he says. "Scientists who study natural products take their cues from what nature has already done. We're adding deep biochemical meaning to this area." He adds that synthetic chemists hope that actin-b...

Brain size may depend upon how neural cells are cleaved

..., we knew that heterotrimeric G proteins were very good candidates as regulators of the plane of cell division in neural precursors," said Tsai. "And this is a very important question, because how these cells divide ultimately determines the final number of cells that will be generated during brain devel...
