It's never too late to get it back! Aging interrupted

...ls to provide energy when it is starving. Then it replaces these cells when a meal is eaten. It seems it is the total number of calories which are consumed, rather than the type of food which is the key to the effects of low calorie diets on the ageing process. However, it is known that vegetarians and f...

Scientists learn the origin of rogue B cells

.... In normal circumstances, this new, good receptor replaces the bad one, but what Casellas and Dr. Patrick C. Wilson of the Oklahoma Medical Research Foundation found was that about 10 percent of the body's B cells retain both receptors: a good, useful one and the faulty self-reactive one that the good recept...

Lead with a poisonous electron shield

...s, three of which involve a sulfur atom. When lead replaces zinc, it only binds to the three sulfur atoms. The reason for this is the emerging free electron pair of the lead cation. It acts as an electronic shield on one side, pushing away the fourth ligand. Such a dramatic geometrical distortion at the activ...

Researcher studies, treats military with 'silent disease'

...nt had cirrhosis, a condition in which scar tissue replaces healthy tissue, blocking the flow of blood through the organ and preventing it from working as it should. Cirrhosis is the twelfth leading cause of death by disease, killing about 26,000 people each year, according to The National Digestive Diseases ...

The molecular post office inside the cell

...w the receptor interacts with ribosome and SRP and replaces parts of the SRP molecule. In this way, specific sites are made available for the translocon, which allows it to bind to the ribosome. Understanding this key event during protein sorting is essential to understanding how secretory and membrane protei...

MIT 'seeing machine' offers hope to blind

...c feedback of the SLO. The new seeing machine also replaces the laser of the SLO with light-emitting diodes, another source of high-intensity light that is much cheaper. Like its inspiration, the seeing machine is designed to be used by one eye. The pilot clinical trial of the seeing machine involved visuall...

Wisconsin scientists grow two new stem cell lines in animal cell-free culture

...remaining animal products such as bovine serum and replaces them with products of human origin in a recipe that is completely defined. But while the new Wisconsin work represents an important advance for stem cell technology, the ability to now grow embryonic stem cells in cultures free of animal products co...

Mouse study reveals human X-SCID gene therapy poses substantial cancer risk

... Genetics, discovered that the healthy copy, which replaces the defective gene can itself promote cancer development. Their findings appear in this week's issue of the journal Nature. Niels-Bjarne R. Woods, Ph.D., a post-doctoral researcher in Inder Verma's team followed mice treated with the IL2RG gene thre...

UW-Madison scientists zero in on drugs' sweet spots

...se are very complex molecules." The new technique replaces enzymes, biological catalysts, with a robust chemical method, allowing researchers to easily manipulate and exchange the sugars found in natural agents. Critically, the method allows medicinal chemists to investigate the biological effects of the ma...

Computers close in on protein structure prediction

...others like their distance. In stage two, Rosetta replaces the fuzzy picture of the side chains with detailed, physically realistic models with all the atoms represented. From the positions of the atoms in the sidechains and the protein backbone, the computer then uses a detailed physical chemistry based for...

Ophthalmologists implant five patients with artificial silicon retina microchip

... that removes the gel in the middle of the eye and replaces it with saline. They then make a pinpoint opening in the retina through which they inject fluid to lift up a portion of the retina from the back of the eye, creating a small pocket in the "subretinal space" just wide enough to accommodate the ASR. T...
