Unlike genetic mutations previously linked to rare, inherited forms of early-onset Alzheimer's disease — which can strike people as young as their 30s or 40s —…
By manipulating a specific gene in a mouse blastocyst — the structure that develops from a fertilized egg but is not yet an actual embryo — scientists with the…
The research suggests that it is not size alone that gives more brain power, but that, during evolution, increasingly sophisticated molecular processing of…
The bacterium that commonly causes stomach ulcers in humans is called Helicobacter pylori. Extensive research has been carried out on this bacterium and the…
A team of researchers at Harvard University have modeled in the laboratory a primitive cell, or protocell, that is capable of building, copying and containing…
Like human hands, many molecules that make up drugs come in two shapes, right and left. But usually only one of the two versions has the desired effect; the…
While niacin can increase plasma HDL levels, the mechanism of how it works has been mysterious, although it's believed that niacin does not actually increase…
Through both the normal aging process and external factors like UV damage, smooth, young skin inevitably becomes coarse and wrinkled. The basis of this…
Strain S19 is a naturally occurring strain of B. abortus that does not cause disease and was discovered by Dr. John Buck in 1923. It has been used for more…
Their study, published in the journal Molecular Cell, reveals a key mechanism in the interplay of molecules that allows cells to build the proteins needed to…
Today there is no single test or biomarker that can predict whether a particular person will develop Alzheimer´s disease and a definitive diagnosis is only…
Aaron Levine, assistant professor of public policy and author of the book Cloning: A Beginner’s Guide, studied how countries output of research papers related…
Researchers from the School of Medicine, Swansea University took samples from visitors to the Cheltenham Science Festival yesterday (Thursday 5 June 2008) to…
The technique, developed by University of Leeds engineers, is a potentially invaluable tool in drug manufacture, where controlling crystal forms is crucial…
When it comes to alternative fuels, currently ethanol is king. Almost all ethanol produced in the United States is fermented from readily available sugars in…
That is welcome news for ecologists and farmers in the debate over GM plants. Much of the debate surrounding the use of GM crops focuses on their effect on…
