'Molecular computers' act as tiny ID tags
19.9.2006 | Press monitoring
Molecules capable of basic logic operations have been developed that could serve as tiny ID tags for identifying individual cells or nano-devices. The technique, called molecular computational identification (MCID), could produce tens of millions of unique tags.

Nanoscientists have transformed a molecule of chlorophyll-a from spinach into a complex biological switch that has possible future applications for green energy, technology and medicine.
New Generation Of Super Microscopes Poised For Scientific Use
17.9.2006 | Press monitoring
Super-high resolution optical microscopes, with powers that seemed physically impossible a decade ago, are poised to open a new era in imaging in molecular biology, according to a report scheduled for the Sept. 4 issue of Chemical & Engineering News, the ACS' weekly news magazine.
Live H5N1 avian flu virus vaccines show protection in animal studies
16.9.2006 | Press monitoring
When tested in mice and ferrets, experimental vaccines based on live, weakened versions of different strains of the H5N1 avian influenza virus were well-tolerated and protected the animals from a deadly infection with naturally occurring H5N1 flu viruses. The findings, which appear in the September 12 issue of PLoS Medicine, are also encouraging,...
Getting nanowires on the brain
16.9.2006 | Press monitoring
Researchers from Harvard University, US, have linked nanowire field-effect transistors to neurones, cells found in the brain and nervous system that create and transmit electrical signals. As well as offering the potential for hybrid biological/electronic devices and interfaces to neural prosthetics, the technique could provide high-resolution...

NORWICH (Reuters) - Enzymes rather than scarce and expensive platinum may hold the answer to the hydrogen fuel cells of the future to halt global warming and as the oil runs out, a scientist said on Wednesday.
Anti-inflammatory Drug Prevents Liver Cancer In At-risk Liver Patients
14.9.2006 | Press monitoring
Colchicine, an anti-inflammatory drug most often used to treat gout, prevented liver cancer in patients with hepatitis virus-related end-stage liver disease, according to a new study. Published in the October 15, 2006 issue of CANCER, a peer-reviewed journal of the American Cancer Society, the study found that over three years of follow-up,...
Ultrasound Delivers Therapeutic Molecules Into Living Cells
14.9.2006 | Press monitoring
Researchers have shown how ultrasound energy can briefly “open a door” in the protective outer membranes of living cells to allow entry of drugs and other therapeutic molecules – and how the cells themselves can then quickly close the door. Understanding this mechanism could advance the use of ultrasound for delivering gene therapies, targeting...
