African parasite makes component of fat differently from all other organisms
...ies in a host's bloodstream. There, the parasite avoids detection by the human immune system by replacing each of the 10 million proteins on its outer layer - known as the cell membrane - with different proteins that are not recognized by immune cells. These proteins are attached to the cell membrane by a...Story tips from the Department of Energy's Oak Ridge National Laboratory, June 2006
...es not use external labels for detection, and thus avoids the need to use ultraviolet sources and optics to scan the information. In addition, the system uses cantilevers that have not been coated with receptor molecules, thereby avoiding cost and coating uniformity issues. The result of this patented techn...Who are we up against? Local vs. global competition influences cooperative behavior in humans
...ng at reciprocal cooperation is that participation avoids any punishment that would be handed out to non-collaborators. The impact of repeated interactions has been examined in the past by observing humans asked to play the Prisoner's Dilemma game. The dilemma in this game is that not cooperating (that is, ...Researchers look to nature for design inspiration

These approaches include transplantation of normal photoreceptor cells into the eye or implantation of electronic retinal "chips" to replace the photoreceptor function....New study suggests schools should add nondairy beverages to the lunch menu

The majority of African-Americans, Asian-Americans, and Hispanic-Americans are lactose intolerant.

...ase Center at UT Southwestern. The gene injection avoids a serious side-effect that caused the cancellation of a previous multi-center human trial with amyloid-beta 42, researchers said. UT Southwestern did not participate in that trial. In that earlier study, people received injections of the protein itse...Gene therapy for muscular dystrophy fixes frail muscle cells in animal model, Stanford study finds
... rely on a virus to disperse the DNA and therefore avoids some of the issues, including cancer and an immune reaction, that have turned up in viral gene therapy trials. Instead this approach uses naked DNA that travels through the bloodstream to cells of the body. For his part, Rando said that no matter how...Drunken elephants: The marula fruit myth
...xication would minimally require that the elephant avoids drinking water, consumes a diet of only marula fruit at a rate of at least 400 percent normal maximum food intake, and with a mean alcohol content of at least 3 percent," write the authors. Instead, the authors posit that an intoxicant other than al...Preclinical study of a new brain tumor therapy

The researchers found that the treatment was effective in mice implanted with human brain tumor cells that overexpressed EGFR. The treatment could eliminate established cancers and there was no evidence of recurren...The unfolding of amyloid's true colors

But Mickelson and his colleagues found they could do it. They were able to insert a pacing lead into the pericardial space, and the puncture site healed with...Neurologix announces positive results of gene therapy clinical trial in Parkinson's disease

Using the new technique, the researchers were able to visualize the muscle tissue in a form closer to its structure in the body than had previously been possible.
