Purdue creates self-generating nanotubes with 'dial-up' properties
...the outside of the spiral, the team has learned to attach other molecules, which hang off the tubes like charms on a charm bracelet. The attached molecules then lend their properties to the outside of the nanotube. For example, if the component molecules of nylon are attached, the nanotubes can then be tur...Rice bioengineers develop method to grow 3-D bone matrix

The mussel fibers consist largely of proteins, but one percent of their weight content is metallic--copper, zinc, or iron.

...er studies confirmed that the enzymes did, indeed, attach themselves to the receptors. To discover the role of beta-arrestin, the scientists tried the same experiment in cells engineered to lack beta-arrestin -- which occurs in two forms, beta-arrestin1 and beta-arrestin2. In those experiments, they found ...Scientists identify role of important cancer protein
...roteins, the cytoplasmic signaling proteins cannot attach to their nuclear counterparts. "This binding process is probably one of the major ways in which Ski disrupts the signaling proteins and, thus, suppresses the action of TGF-b," Shi says.

...cture reveals that parts of the LDL binding region attach to the "beta-propeller" region at low pH and thus cannot bind to LDL. It looks as if the "beta-propeller" region competes with LDL, Deisenhofer said. "The LDL receptor is crucial to clearance of LDL and in keeping your cholesterol levels healthy," Ru...Coral layers good proxy for Atlantic climate cycles
... coral begins to grow over the surface. They even attach a platform to the coral before they drill so that their hands do not damage the animals. "The only part of the coral that is living is a few millimeters on the top of the core," says Greer. "This is quickly replaced once the hole is filled."...Nanoparticles could aid biohazard detection, computer industry
... of Nano Letters, sprang from the team's desire to attach metals to semiconductors in precise locations. Computer chips, commonly made of silicon, contain circuits that are far smaller than those made from metal wires. But for an impulse from a keyboard or mouse to reach the microchip, the electronic signa...Observing proteins and cells in the wild
...eadily bind antibodies, the researchers could then attach the dots to their protein-specific antibody of choice. The critical test was to determine specificity: can quantum dots achieve the same exquisite selectivity that occurs when a protein is synthesized fused to GFP? To answer this question, Simon and ...Researchers developing new arsenal in war against cancer
...ens up huge new areas for fighting cancer. "We can attach the delivery vehicles, change the light we need, change the biological target in the cells, and design a molecule that reacts with that part," Brewer said. In other words, Brewer can develop different molecules for different areas of the cells, Storr...Smart polymers provide light-activated switch to turn enzymes on and off
