In their final report, the scientists call for improved conservation management of the region to address and halt threats from ...

Simulations unravel outer membrane transport mechanism

... in the system, the researchers ran simulations of various scenarios to test which hypotheses were most feasible. Their work relied on detailed crystallographic studies of the molecules provided by University of Virginia researcher Michael C. Wiener. “The good thing about simulations is that you can monit...

Newly found sensing system enables certain bacteria to resist human immune defenses

...se anthrax, strep throat, flesh-eating disease and various types of food poisoning. In gram-negative bacteria—such as those that cause plague and salmonellosis—a sensory and gene regulation system named PhoP/PhoQ protects invading bacteria, and scientists believe if they develop a better understanding of ...

Sun exposure early in life linked to specific skin cancer gene mutation

...bout their risk factors for melanoma and about the various places they had lived. Each patient's UV sun exposure was estimated from their residential history and satellite-base measurements. DNA from the patients' melanomas was then analyzed for mutations. Patients with melanomas that contained the BRAF m...

Mutating the entire genome

...multiple generations of mice with loxP surrounding various large stretches of DNA. Then the first part of the new method is used: The mice are bred with mice that carry the Cre gene so any large stretch of DNA that is located between two short pieces of loxP DNA can be mutated. Because the whole mous...

Blood-brain barrier breached by new therapeutic strategy

These methods involve invasive procedures that result in only localized delivery around the site of injection. The new research provides a safe and non-invasive method for delivering thera...

Weizmann Institute scientists develop a general 'control switch' for protein activity

...known. To reveal this function, scientists perform various genetic manipulations to increase or, conversely, decrease the production of a certain protein, but existing manipulations of this sort are complicated and do not fully meet the researchers’ needs. Prof. Mordechai “Moti” Liscovitch and graduate stud...

Researchers develop buckyballs to fight allergy
