Technique could lead to new drug delivery systems, biological warfare sensors
Using a lab technique called domain insertion, Johns Hopkins researchers have joined two proteins in a way that creates a molecular “switch.” The result, the researchers say, is a microscopic protein partnership in which one member controls the activity of the other. Similarly coupled proteins may someday be used to produce specialized molecules that deliver lethal drugs only to cancerous cells. They also m
Mobile DNAs role in vancomycin resistance of Enterococcus faecalis
‘Jumping’ elements of DNA have enabled the bacterium Enterococcus faecalis to acquire stubborn resistance to a range of antibiotics – including a “drug of last resort” that is used against such bacterial pathogens.
That is one of the conclusions reached by scientists at The Institute for Genomic Research (TIGR), which sequenced and analyzed the complete genome of E. faecalis V583, a strain of the
Researchers at the University of California, San Diego have discovered how to transfer the optical properties of silicon crystal sensors to plastic, an achievement that could lead to the development of flexible, implantable devices capable of monitoring the delivery of drugs within the body, the strains on a weak joint or even the healing of a suture.
The discovery is detailed in the March 28 issue of Science by a UCSD team that pioneered the development of a number of novel optical sensor
Timing of childbirth cited as key factor
Europe’s population has aged to such a degree that it will likely continue to shrink, even if birthrates rebound to a one-for-one replacement level, a new study suggests. A major part of this trend is due to the fact that women have been postponing childbirth for increasing lengths of time, the authors have found. Their research appears in the journal Science, published by the American Association for the Advancement of Science (AAAS).
The manufacture of electronic devices such as the new generation of video mobile phones could be revolutionised thanks to assembly research being pioneered at the University of Greenwich.
This research will provide industry with the microsystems assembly technology to allow cheaper mass production of the next generation of intelligent products, such as mobiles, visual display equipment and medical devices. It could, for example, be used to develop minute invisible hearing aids.
A pulsed electric arc could provide an alternative to chlorination and other chemical methods of disinfecting water, according to researchers from the University of Poitiers, France, speaking to the Institute of Physics Congress on March 27 at Heriot-Watt University.
Water treatment is usually carried out using chlorine-containing disinfecting agents but these produce by-products that are coming under increasing scrutiny by the European Community. Chemical agents to destroy pollutants
