To reduce the severity of his seizures, Joe had the bridge between his left and right cerebral hemisphers (the corpus callosum) severed. As a result, his left and right brains no longer communicate through that pathway. This is an extraordinary insight into the machinary of the mind. Here’s what happens as a result:

All the crucial proteins in our bodies must fold into complex shapes to do their jobs. These snarled molecules grip other molecules to move them around, to speed up important chemical reactions or to grab onto our genes, turning them “on” and “off” to affect which proteins our cells make.

In a novel experiment, a USC biomedical engineer examines the intricate circuitry between hand manipulation skills and specialized neural circuits in the brain Quickly moving your fingertips to tap or press a surface is essential for everyday life to, say, pick up small objects, use a BlackBerry or an iPhone. But researchers at the University [...]

The GelSpray Liquid Bandage is a major advance in the management and care of combat casualty and civilian wounds. Much like epoxy is dispensed in household kits, the dressing is applied with a dual syringe that releases two polymer ingredients. These polymers react rapidly upon mixing to form a gel-based dressing that frontline combat soldiers [...]
Lab-on-a-Chip Breaks Protein-Expression Bottleneck
Posted by: Derya on: February 4, 2008
The Nucleic Acid Programmable Protein Array (NAPPA) was developed at the Harvard Institute of Proteomics and led to the spin-out of Auguron about a year ago. The firm says this technology enables proteins from any gene in the genome to be generated on microchips from surface printed DNA.
