Researchers have known for some time that the blood vessels that transport blood to and from tissues and organs in the body are more than just bodily pipelines. Arterioles and capillaries, the small vessels, actually play a key role in regulating the flow of the blood they're carrying. Biomedical engineers at Drexel University, who study cardiovascular function, are creating a mathematical model that explains just how they do it.
A team of researchers have found evidence that altering the chemistry of an electrode surface can help microbial communities to connect to the electrode to produce more electricity more rapidly compared to unmodified electrodes. Practical applications of these systems include current generation, wastewater treatment, and biochemical and biofuel production.
The SeaBioTech project, started in 2012, is intended to close some of these knowledge gaps by looking in the seas and oceans around the globe for life forms with novel properties. The aim is to find raw material for the world's biotechnology industry, with a particular emphasis on antibiotics and other medical compounds.
Demystifying the chemical processes that create a wine's aroma, and the invaluable potential application of that understanding in winemaking, is the new objective of scientists in Uruguay who, with European partners, also recently sequenced the genome of the high-value Tannat grape, from which 'the most healthy of red wines' are fermented.
Biological cells are surrounded by a membrane, and here some of the most important processes for sustaining life take place. There can also be something very beautiful happening in membranes, researchers from the University of Southern Denmark have discovered: Membranes can contain beautiful, mysterious patterns.
University of Washington researchers have performed what they believe is the first noninvasive human-to-human brain interface, with one researcher able to send a brain signal via the Internet to control the hand motions of a fellow researcher.
Researchers report on a new software tool known as DeNovoGear, which uses statistical probabilities to help identify mutations and more accurately pinpoint their source and their possible significance for health.
