The collaboration between cardiologist and orthopedist may at first seem novel, if not odd. But just such an interdisciplinary connection at the University of North Carolina at Chapel Hill has yielded potentially useful fruit: a bioengineered, rhythmically beating experimental model of heart muscle.
The new model system is a bioartificial trabeculum, or BAT. Trabecula are thin sections of cardiac tissue within the inner surface of the hearts main pumping chambers. Although still some
How can new technologies help to reveal the hidden lives of tropical animals and plants?
Difficult environmental conditions and complex biological interactions make it tough for tropical biologists to understand animal behavior, climate change effects and highly biodiverse plants and forest organisms. On Monday, July 29, 2002, the Smithsonian Tropical Research Institute (STRI) convened a diverse group of rainforest biologists with engineers at the forefront of sensor and communicatio
A physics professors invention to decontaminate industrial wastewater could become a powerful new weapon against anthrax.
Peter McIntyre and a group of colleagues at Texas A&M University have developed a cost-effective device to produce high energy electron beams that can break down harmful organic molecules in water – and destroy bacteria such as anthrax in food – or even on mail.
“William Cooper at the University of North Carolina showed that high-powered beams of e
On July 30th 2002, the engineers and scientists of the Association Euratom-CEA in Cadarache (France) have achieved a three and a half minutes long plasma discharge on Tore Supra, sustained by 3MW of current drive power, thus requiring to exhaust more than 600 Megajoules of thermal energy during the experiment. It establishes a new world record in this domain after the 280MJ discharges of 1996. Prior to the record discharge, a number of long pulse shots have been achieved, demonstrating the capability
When physicists sandwiched together different types of semiconductor to create the first transistor in 1947, they made bulky vacuum valves obsolete and so revolutionised the electronics industry. Since then researchers have been pushing the boundaries of semiconductor technology hoping for another revolution. At the 26th International Conference on the Physics of Semiconductors in Edinburgh from 29 July to 2 August, progress towards ultra-high density magnetic recording, and a new branch of nanotech
Health officials fear that lifesaving drugs can lose their effectiveness when overused. They are especially concerned about anti-microbial additives, found in everything from kitchen cleaners to face soaps, because the bacteria they try to kill are becoming resistant. Clemson University scientists have found a new bacteria fighter that does not promote bacterial resistance.
Food microbiologist Susan Barefoot and doctoral student researcher Priya Ratnam uncovered a new acne treatment that a
