Bright quantum dots help basic cancer biology studies
March 27th, 2008
Though there is little doubt that nanoscale devices are going to play a critical role in improving cancer detection and treatment over the next five to ten years, nanoparticles are already having a major impact on the way that cancer biologists study the processes that go awry within malignant and metastatic cells.

New type of nanoparticle created by spray pyrolysis
March 26th, 2008
Researchers at the University of California, Davis, have created a new type of nanoparticle that could be used in tests for medical diagnostics, environmental pollution, and contamination of food products. Read more
Human proteins evolving slowly thanks to multi-tasking genes
March 26th, 2008
Many human proteins are not as good as they might be because the gene sequences that code for them have a double role which slows down the rate at which they evolve, according to new research published in PLoS Biology. Read more
Horse genome sequence assembled
March 25th, 2008
The first draft of the horse genome sequence has been deposited in public databases and is freely available for use by biomedical and veterinary researchers around the globe, leaders of the international Horse Genome Sequencing Project announced today.<?XML:NAMESPACE PREFIX = O /> Read more
Loss of a universal tRNA feature
March 25th, 2008
Scientists at the Virginia Bioinformatics Institute (VBI) report in the Journal of Bacteriology that two alphaproteobacteria lack the universal extra guanylate nucleotide typically found in the transfer RNA molecule tRNAHis. tRNAs are the molecules responsible for decoding sequence information specified by messenger RNA molecules, information...

Natural molecules to create pseudo-cell factories
March 24th, 2008
Carnegie Mellon University's Philip LeDuc predicts the use of artificially created cells could be a potential new therapeutic approach for treating diseases in an ever-changing world. Read more
Scientists discover master switches for adult blood stem cells
March 24th, 2008
Johns Hopkins Kimmel Cancer Center scientists have found a set of "master switches" that keep adult blood-forming stem cells in their primitive state. Read more
Scientists find connection between nerve cells and immune system
March 23rd, 2008
A direct connection exists between the brain and the immune system - at least in mice. Scientists at the Helmholtz Centre for Infection Research in Braunschweig conducted a comprehensive study of mice intestine and the surrounding blood and lymph vessels using special microscopy and marking techniques.

Scientists discover enzym that activates epigenetically silenced genes
March 23rd, 2008
For several years now, cancer researchers have been studying a mechanism that contributes to the development of malignant tumors: The cell attaches small molecules containing a carbon atom, called methyl groups, to specific building blocks of DNA, thereby individually switching off the genes thus labeled.
