Using a unique and relatively simple cell-based fluorescent assay they developed, scientists with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC), Berkeley have ide…
Australian researchers have identified a way to measure the structure of membrane proteins despite being damaged when using X-ray Free-Electron Lasers (XFELs), a discovery that will help fast track the development of targeted drugs using emerging XF…
Like an overprotective parent on the first day of school, a targeting factor sometimes needs a little push to let go of its cargo. Scientists at the European Molecular Biology Laboratory (EMBL) in Grenoble, France, have visualised one such hand-…
The researchers characterize their new technique as a neat solution to the “needle in a haystack” problem of nanoscale microscopy, but it’s more like the difference between finding the coffee table in a darkened room either by walking around u…
A protein defective in two types of muscular dystrophy also appears to be important in repairing damaged muscle, according to Howard Hughes Medical Institute researchers at the University of Iowa College of Medicine. The discovery reveals the first known component of the machinery that repairs the damaged membrane in a muscle fiber. Further studies of this and related proteins could lead to a better understanding of disorders that affect cardiac and skeletal muscles.
Researchers at the University of Rochester have created the highest resolution optical image ever, revealing structures as small as carbon nanotubes just a few billionths of an inch across. The new method should open the door to previously inaccessible chemical and structural information in samples as small as the proteins embedded in a cell’s membrane. The research appears in today’s issue of Physical Review Letters.
