MIT engineers probe spiders' polymer art
...ed spaghetti. They form a viscous solution but are slippery
enough to slide past each other easily and squeeze through the spider's ampullate gland. As the silk gel flows from the gland through an S-shaped, tapered canal to the outside of the spider's body, the long protein molecules become aligned and the vi...
Researcher gives hard thoughts on soft inheritance
...netics as soft inheritance in mammals puts us on a slippery
slope that many people don't want to visit," Richards says. Nutritional epigenomics Still, recent studies in mice and rats have fueled the controversy. Richards cited "a whole new world called nutritional epigenomics," where rese...
Sticky surfaces turn slippery with the flip of a molecular light switch
Changing a surface from sticky to slippery
could now be as easy as flipping a molecular light switch. Researchers at Rensselaer Polytechnic Institute have created an "optically switchable" material that alters its surface characteristics when exposed to ultraviolet (UV) light. The new materia...

film on ship hulls. If a single cell were analogous to one man, biofilms would be the "bacterial equivalent of mob mentality," says Blackwell. In the realm of health, biofilms are at the root of growing numbers of tenacious, and sometimes fatal, hos...
Ice core 'dipstick' indicates West Antarctic ice has thinned less than believed
... and gradual decline would have had to have a very slippery
bed to maintain its continuous flow, Waddington said, and it appears the ice flowed vigorously despite being relatively thin. One major implication of the research, he said, is that it disputes the theory that West Antarctic ice streams retreated wh...
