(Phys.org) —Rice University bioengineers are developing a simple, highly accurate test to detect signs of HIV and its progress in patients in resource-poor settings.
Plants cut the mustard for basic discoveries in metabolism
You might think you have nothing in common with mustard except hotdogs. Yet based on research in a plant from the mustard family, Salk scientists have discovered a possible explanation for how organisms, ...
Better combustion through plasma
Mix together air, fuel, and heat and you get combustion, the chemical reaction that powers most engines in planes, trains and automobiles. And if you throw in some ionized gas (plasma), it turns out, you can sustain combustion ...
Researchers uncover a synthetic material that rebuilds itself through chemical communication
(Phys.org)—Self-moving gels can give synthetic materials the ability to "act alive" and mimic primitive biological communication, University of Pittsburgh researchers have found.
Team changes game for synthesizing new materials
University of Oregon chemist David C. Johnson likens his lab's newly published accomplishments to combining two flavors of ice cream—vanilla and chocolate—and churning out thousands of flavors to appeal ...
