...ontact angle whichexceeds 90 degrees. However, the bulge arising from this instability maycoalesce with a neighboring channel and thus lead to a microbrigde between twochannels. These bridges can be used to construct fluid microchips ormicroreactors.

...t a police barricade. The cell membrane begins to bulge and eventually forms a "bubble" that seals the viral RNA off from the rest of the cell (see accompanying illustration). Thousands of newborn viruses now cling to the outside of the membrane, waiting for one final step to cut them loose and send the...Battle of the DNA bulge may help thwart cancer

A DNA bulge occurs where an extra base winds up on one side of the DNA strand. "A bulge is like having a ladder...New method of identifying and isolating stem cells developed
...cycling cells have been found in a "niche," a tiny bulge halfway up the side of a hair follicle shaft. Similar niches have been found in the eye's cornea and in intestinal cells, and are suspected to be present in several different tissue systems. Researchers discovered several years ago that skin niche ce...Simple sugars make cell walls like steel
...of normal. "They are really flimsy cells and they bulge out. Instead of being really nice and columnar as this tissue usually is, they get a little flabby. We deduced that these galactose appendages are required for XET to recognize where to clip the xyloglucans to allow expansion and then to retie them."...Stem cells offer promise for hair growth
...pected that stem cells located within the follicle bulge were responsible for hair growth. To test their theory, they used sophisticated cell labeling techniques to track the decedents of the stem cells during normal hair growth and isolate them in adult mice. They transplanted a slurry of these cells into...Skin stem cells give hairless mice hair
