The first artificial human prion has been synthesized, report researchers at Case Western Reserve University School of Medicine. This is an important development in efforts to combat a devastating form of brain disease that has so far eluded treatment and a cure. Prions are proteins that have folded incorrectly. They can bind to neighboring normal… Read more

A new form of microscopy that allows the observation of the formation and evolution of cell membrane focal adhesions has been developed by researchers at the Beckman Institute for Advanced Science and Technology and the Micro and Nanotechnology Laboratory at the University of Illinois. Their paper details how the new live cell imaging technique, called… Read more

Norovirus infects a rare type of intestinal cell called a tuft cell, so named because each cell sports a cluster of hairlike extensions on its surface, researchers at Washington University School of Medicine in St. Louis recently demonstrated. While tuft cells are few in number, the scientists’ findings indicate that once the virus strikes, such… Read more

All the genes required by a bacterium to use methanol as a food source have been identified by ETH Zurich researchers. The results will help scientists advance the use of this resource in the field of biotechnology. Many chemists are currently researching how small carbon molecules, such as methane and methanol, can be used to… Read more

A method for keeping private genetic information protected when scouring complete human genomes for the presence of disease-associated genes has been developed by Stanford researchers. The “genome cloaking” technique eases many concerns about genomic privacy and potential discrimination based on an individual’s genome sequence. Using the technique, the researchers were able to identify the responsible… Read more
