UAB scientists discover the origin of a mysterious physical force

...ate cell membranes to enter cells. These drugs are often proteins designed to prevent or strengthen the action of other substances. In these cases, accurately identifying the protein folding is essential, since the form these proteins take on when they fold influences how effectively they are able to act. ...

New, automated tool successfully classifies and relates proteins in unprecedented way

...ssigned manually by database curators, and this is often notconsistent between different curators," said Murphy.Murphy and his colleagues are currently amassing more protein imagedata using CD Tagging so that they can refine their approach further.They are also working on ways to "train" a general system t...

Recent breakthroughs in common adult leukemia highlighted in New England Journal of Medicine

...n 20 years after diagnosis. Since the disease most often strikes older adults, the patients whose disease follows this course usually die with the disease, not because of it. CLL may also follow a more aggressive course. In these cases, patients do require chemotherapy and have a lifespan of only about six...

Another Look Finds Promising Proteomics Test is Not Biologically Plausible

...ery important task," said Professor Williams. “We often think of flu as just a nasty illness which puts us in bed for a few days. But some outbreaks can cause death on a large scale ?the world-wide outbreak in 1918 killed more people than the First World War itself. We may now be facing another flu outbre...

Inexpensive, mass-produced genes core of synthetic biology advances at UH

"Conservation organizations such as WCS are therefore critical to the early detection of the conditions that can lead to deadly health emergencies." ...

U-M scientist to talk about tissue engineering at AAAS

Gene therapy converts dead bone graft to new, living tissue
