NYU researchers simulate molecular biological clock

... associate professor of biology Christopher Burge, provides thefirst evidence that microRNAs influence a large percentage of life'sfunctions.The team developed a computational method to define the relationshipbetween microRNAs and their target genes. In December 2003, the samegroup identified 400 genes in the...

Mitochondrial DNA mutations play significant role in prostate cancer

Poplar trees redirect resources in response to simulated attack

...esponse to a simulated insect attack. The research provides new insights on a long-debated theory about how plants respond to environmental stress, and shows that radiotracer imaging can be a big help in unraveling plant biochemistry. Done in collaboration with scientists from Tufts University and Stony Broo...

Vital step in cellular migration described by UCSD medical researchers

Taking Aim With Nanoparticle PEBBLEs

...cules that make PEBBLEs more visible in MRI images provides an added bonus, helping to show where tumors are located and how they respond to treatment. In recent experiments with a small number of rats that had a type of brain cancer called 9L-gliosarcoma, PEBBLE-based treatment significantly increased survi...

Open microfluidic and nanofluidic systems

The new PNAS study provides an instructive example for the close relation between basic research and technological development in the micro- and nanoregime: open systems with directly accessible surface channels can be used for micro- and nanofluidic applications but only if on...

Nanogen Issued Patent for Electronic Microarray With Memory

...lar diagnostic tests. Using local memory circuits provides for precise control of the currents delivered to individual electrodes on the array, while minimizing the utilization of "off-chip" circuitry and overall system costs. The electric potential is controlled at each of the NanoChip's 400 test sites to m...
