Tiny blood vessels, viewed beneath a mouse’s skin with a newly developed application of multiphoton microscopy, appear so bright and vivid in high-resolution images that researchers can see the vessel walls ripple with each heartbeat — 640 times a minute.
The capillaries are illuminated in unprecedented detail using fluorescence imaging labels, which are molecule-size nanocrystals called quantum dots circulating through the bloodstream. Quantum dots are microscopic metal or semiconductor
A new method to accurately measure quantities of a cheese-ripening enzyme in milk could reduce the time and cost of producing cheese, according to a report by Purdue University researchers.
Infrared spectroscopy was used in combination with statistical analysis to determine the concentration of plasminogen, a form of the enzyme integral to cheese manufacturing. The study, by co-authors Lisa Mauer and Kirby Hayes, both assistant professors in the Department of Food Science, is published in th
Protein could be used as a treatment for Alzheimer’s, Parkinson’s, and Huntington’s disease
A team of researchers from Imperial College London, the Charing Cross Hospital and University College London have identified a protein which could be used to protect against neuro-degenerative conditions such as Alzheimers, Parkinsons, Huntingtons, motor neurone diseases and the damage caused by strokes.
According to research published today in The Journal of Biologi
Ohio University engineers are leading one of the first comprehensive efforts to examine how fuel cell technology could pave the way for cleaner coal-fired power plants. Supported by a $4 million U.S. Department of Energy grant secured by the Ohio Congressional delegation, the project aims to find ways to use coal – the environmentally dirtiest but most abundant fossil fuel in the world — to harness high-efficiency fuel cells.
Most government-sponsored energy research is focused on using nat
Single-molecule switches have the potential to shrink computing circuits dramatically, but new results from the Arizona State University lab that first described how to wire a single molecule between gold contacts now show that laboratory-standard wired molecules have an unavoidable tendency to “blink” randomly.
In the May 30, 2003, Science, Stuart Lindsay and colleagues identify the cause of this blinking behavior as random, temporary breaks in the chemical bond between the wired molecule
Assisted reproduction can safely help HIV positive men to become fathers without infecting their partners, according to new research from French fertility experts.
But, the news is not so good for HIV positive women. Assisted reproduction techniques do not seem to provide the same success for them, the researchers reported today (Thursday 29 May) in Europe’s leading reproductive medicine journal Human Reproduction[1].
Dr Jeanine Ohl and her Strasbourg-based team carried out various
