Researchers identify molecules with interesting anti-clotting properties
11-08-2007 · EurekAlert!Virginia Commonwealth University researchers have discovered a new mechanism to inhibit key enzymes that play a major role in clotting disorders, which could lead to novel therapies to treat clots in the lungs and those localized deep in the body in areas such as the legs.

- Selecting life: Scientists find new way to search for origin of life
11-09-2006 · EurekAlert!
Over the last half century, researchers have found that mineral surfaces may have played critical roles activating molecules that would become essential ingredients to life. Identifying which biomolecule/ mineral surface pairs, however, has stumped scientists for years because of countless possible combinations. Now a team of researchers, led by Robert Hazen of the Carnegie Institution's Geophysical Laboratory, has developed new protocols and procedures for adapting DNA microarray technology to rapidly identify promising molecule/mineral pairs.

- Chemists strike gold with new gold catalysts
03-23-2007 · EurekAlert!
Few people look beyond gold's glitter and rarity, but chemists have found that its chemical properties are just as interesting, making it a unique catalyst for producing unusual organic molecules. UC Berkeley's Dean Toste, a leader in the area of gold catalysis, attributes these properties to relativistic effects in the gold atom, the same effects that give gold its yellow luster.

- Does neural cell adhesion molecule-180 predict survival in colorectal cancer?
11-02-2007 · EurekAlert!
As cancer is one of the most fatal diseases worldwide, tumor markers and prognostic criterions are of great interest to researchers. Tumor suppressors and cell adhesion molecules play crucial roles in tumor pathophysiology, acting as potential targets for treatment modalities. NCAM-180 is a structural molecule that mediates cell-cell adhesion, resulting in tissue stabilization. It has been proposed as a tumor suppressor in colon carcinoma. A research group in Turkey has investigated the prognostic value of NCAM-180 in colorectal cancer.

- Biocapture surfaces produced for study of brain chemistry
12-13-2007 · EurekAlert!
A novel method has been developed for attaching small molecules, such as neurotransmitters, to surfaces, which then are used to capture large biomolecules. Researchers can make the technique applicable to a wide range of "bait" molecules including drugs, chemical warfare agents, and environmental pollutants. Ultimately, the researchers also hope to identify synthetic biomolecules that recognize neurotransmitters so that they can fabricate extremely small biosensors to study neurotransmission in the living brain.

- New Brandeis research sheds light on memory by erasing it
05-08-2007 · EurekAlert!
For years, scientists have studied the molecular basis of memory storage, trying to find the molecules that store memory, just as DNA stores genetic memory. In an important study published this week in the Journal of Neuroscience, Brandeis University researchers report for the first time that memory storage can be induced and then biochemically erased in slices of rat hippocampus by manipulating a so-called "memory molecule," a protein kinase known as CaMKII.

- Smart thin film membranes adopt properties of guest molecules
03-28-2007 · EurekAlert!
Virginia Tech researchers announced last year that they had created a nanostructured membrane that incorporates DNA base pairs in order to impart molecular recognition and binding ability to the synthetic material. This year they will show for the first time that these new films, membranes, and elastomers are compatible with diverse organic and inorganic molecules and will adopt properties of the guest molecules.

- Researchers identify molecule that causes destructive lung inflammation in cystic fibrosis patients
11-06-2006 · EurekAlert!
Scientists at Children's Hospital of Pittsburgh of UPMC have identified a protein that is critical to the development of inflammation during lung infection in patients with cystic fibrosis. The identification of this protein, called interleukin-23, is an important finding that gives researchers a specific target for developing new therapies.

- NRC team uses new Quantum Technology to control molecules
10-12-2006 · EurekAlert!
Researchers at the National Research Council Canada have developed a new Quantum Technology, described in the October 13 Web release of Science, which uses laser pulses to control quantum processes. Quantum technologies manipulate molecular scale behaviour for novel applications. The new method uses the electric field of the laser, rather than the usual absorption of light, to control molecules. This strong electric field puts forces on a reacting molecule, steering it towards a specific outcome.

- Clemson scientists shed light on molecules in living cells
08-21-2007 · EurekAlert!
Clemson University chemists have developed a method to dramatically improve the longevity of fluorescent nanoparticles that may someday help researchers track the motion of a single molecule as it travels through a living cell. The chemists are exploiting a process called "resonance energy transfer."
