A new microscope system that can take 3-D pictures of an embryonic mouse organ over 24 to 48 hours has shown Duke Medical Center researchers the first glimpse of the formation of blood vessels during development.

A new study by Duke University researchers provides more evidence that the nitric oxide (NO) system in the life of a cell plays a key role in disease, and the findings point to ways to improve treatment of illnesses such as heart disease and cancer.

Building faultless objects from faulty components may seem like alchemy. Yet scientists from the Weizmann Institute’s Computer Science and Applied Mathematics, and Biological Chemistry Departments have achieved just that, using a mathematical concept called recursion.

One of the more intriguing workhorses of the cell, a protein conglomerate called telomerase, has in its short history been implicated in some critical areas of medicine including cancer, aging and keeping stem cells healthy.

Chemists from UCLA and the University of Washington have succeeded in creating “designer enzymes,” a major milestone in computational chemistry and protein engineering. Designer enzymes will have applications for defense against biological warfare, by deactivating pathogenic biological agents, and for creating more effective medications.

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.

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.

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 prot

University of Oregon scientists say they have identified a gene that is the key switch that allows embryonic cells to form into muscles in zebrafish .

Researchers at the Picower Institute for Learning and Memory at MIT report in the Jan. 24 online edition of Science that they have created a way to see, for the first time, the effect of blocking and unblocking a single neural circuit in a living animal.
