'Lucky 13' as new gene discovery offers further hope for childhood blindness

... may be enough to restore vision. So our findings, together with the recently announced clinical trials, hold great promise." Mutations in LCA5 are relatively rare. As it is a recessive gene, a child would need to be carrying two copies of the gene to develop LCA, one from each parent. However, the disorde...

As a result,...

Progress toward an antitumor vaccine

...ir anchor is a thioether (two carbon atoms coupled together through a sulfur atom). To this end, the carrier protein is first equipped with a spacer, which has an allyl group (two carbon atoms attached by a double bond) at its end. The glycopeptide is coupled to a building block that causes thiols (sulfur–hyd...

Research finds that circadian rhythms dominate all life functions

...ness, the groups of genes that typically oscillate together -- such as genes responsible for the function of an organ or a specific tissue -- are chaotic under this state and don't function as a group. Lack of orchestration can be easily confused with the lack of oscillation. This makes the rhythm much harder...

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

...mann Institute’s Biological Regulation Department, together with Dr. Miri Eisenstein of Chemical Research Support, have recently developed a unique “switch” that can control the activity of any protein, raising it several-fold or stopping it almost completely. The method provides researchers with a simple and...

Putting feelings into words produces therapeutic effects in the brain

... “This is such an exciting study because it brings together the Buddha’s teachings — more than 2,500 years ago, he talked about the benefits of labeling your experience — with modern neuroscience,” Creswell said. “Now, for the first time since those teachings, we have shown there is actually a neurological re...

Normally, Cdk5 works with another enzyme to break up a molecule called NR2B, which is found in nerve-cell membranes and stimulates the cell to fire when a nerve-cell-signaling molecule, or neurotransmitter, binds to it. N...
