Gold nanoparticles for controlled drug delivery
6.1.2009 | Press monitoring
Using tiny gold particles and infrared light, MIT researchers have developed a drug-delivery system that allows multiple drugs to be released in a controlled fashion.
Human hair waste provides nutrients to container plants
5.1.2009 | Press monitoring
Agricultural crop production relies on composted waste materials and byproducts, such as animal manure, municipal solid waste composts, and sewage sludge, as a necessary nutrient source.
Biologists Learn Structure, Mechanism of Powerful 'Molecular Motor' in Virus
4.1.2009 | Press monitoring
Researchers have discovered the atomic structure of a powerful "molecular motor" that packages DNA into the head segment of some viruses during their assembly, an essential step in their ability to multiply and infect new host organisms. The researchers, from Purdue University and The Catholic University of America, also have proposed a...
Newly Found Enzymes May Play Early Role in Cancer
2.1.2009 | Press monitoring
Researchers have discovered two enzymes that, when combined, could be involved in the earliest stages of cancer. Manipulating these enzymes genetically might lead to targeted therapies aimed at slowing or preventing the onset of tumors.
Progress Toward a Biological Fuel Cell?
1.1.2009 | Press monitoring
Biological fuel cells use enzymes or whole microorganisms as biocatalysts for the direct conversion of chemical energy to electrical energy. One type of microbial fuel cell uses anodes (positive electrodes) coated with a bacterial film. The fuel consists of a substrate that the bacteria can break down. The electrons released in this process must...
Nanotechnology May Be Used For Food Safety
31.12.2008 | Press monitoring
A microscopic biological sensor that detects Salmonella bacteria in lab tests has been developed by an Agricultural Research Service (ARS) scientist and university colleagues. The sensor could be adapted to detect other foodborne pathogens as well.
E.coli bacteria can be altered to make fuel
30.12.2008 | Press monitoring
E.coli, a strain of bacteria found in human digestive tracts, can be genetically altered to make fuel, a new study showed.
Biomedical researchers create artificial human bone marrow in a test tube
29.12.2008 | Press monitoring
Artificial bone marrow that can continuously make red and white blood cells has been created in a University of Michigan lab.
Recipe For Capturing Authentic Embryonic Stem Cells May Apply To Any Mammal, Study Suggests
28.12.2008 | Press monitoring
Researchers have what they think may be a basic recipe for capturing and maintaining indefinitely the most fundamental of embryonic stem cells from essentially any mammal, including cows, pigs and even humans. Two new studies reported in the December 26th issue of the journal Cell show that a cocktail first demonstrated to work in mice earlier...
Modified Plants May Yield More Biofuel
27.12.2008 | Press monitoring
Plants, genetically modified to ease the breaking down of their woody material, could be the key to a cheaper and greener way of making ethanol, according to researchers who add that the approach could also help turn agricultural waste into food for livestock.
