Protein suggests a new strategy to thwart infection
The newfound ability of a protein of the intestines and lungs to distinguish between human cells and the cells of bacterial invaders could underpin new strategies to fight infections.
3-D image of malaria 'conductor' aids search for antimalarial drugs
The first three-dimensional image capturing a critical malaria 'conductor' protein could lead to the development of a new class of antimalarial drugs.
Team first to model atomic structures of three bacterial nanomachines
Researchers at UCLA's California NanoSystems Institute have become the first to produce images of the atomic structures of three specific biological nanomachines, each derived from a different potentially deadly bacterium—an ...
New details of the transmission of stimuli in living organisms unveiled
Researchers unveil new details about how cells in a living being process stimuli. The study, partly funded by the Swiss National Science Foundation SNSF, focuses on so-called G-proteins, which help transmit external stimuli ...
Cell's protein-making machines shift modes under stress
Similar to a hybrid car that switches from gas to electric as it drives on major highways and secondary roads, Cornell researchers have discovered that the cell's protein-making machinery, called ribosomes, exists in a hybrid ...
New study brings medicine closer to non-addictive painkillers
Powerful opiate drugs are a mainstay in modern medicine, alleviating pain in both acute and chronic forms. These charms however, bear a curse. Users quickly develop tolerance to their effects, requiring ever-increasing doses ...
High-powered X-ray laser unlocks mechanics of pain relief without addiction
Using a newly developed X-ray source, scientists have revealed how a new type of pain-relievers works - bonding to the same neuroreceptors that morphine does, but without the accompanying physical dependence.
Imaging reveals tiny piece of protein-making machinery
Using powerful advances in imaging technology, researchers at Yale University have visualized a key component deep within the ribosome, the tiny cellular factory that produces nearly all the proteins essential for life.
Scientists gain first glimpse of one of nature's measuring 'rulers'
An international team of scientists, led by researchers from the University of St Andrews in the UK and Guelph in Canada, have used cutting edge X-ray and ultraviolet light studies to reveal the workings of the molecular ...
