Penn researchers show how nanocylinders deliver medicine better than nanospheres
...les align with the flow and persist in circulation considerably longer than any known spherical particles." In this study, the research team used skinny cylindrical nanoparticles composed of synthetic polymers to deliver the anticancer drug paclitaxel to a human lung tumor tissue implanted in mice. The cylinde...Researchers find link between food odors and lifespan in fruit flies

...amoorthy says that this area of research will grow considerably at U-M from implementing plans to set up a high magnetic field solid-state NMR spectrometer facility and an NIH-funded program. ...Palau's coral reefs show differential habitat recovery following the 1998 bleaching event
...eated thermal stress events and water temperatures considerably higher than historical averages. Using underwater digital video cameras, van Woesik and his team examined the rate of coral recovery at 13 different sites, and found that recovery rates increased over time; notably, sheltered bay areas...Arctic ice retreating more quickly than computer models project
..., and that the summer Arctic sea ice may disappear considerably earlier than IPCC projections," says Stroeve. Thirty years ahead of schedule The study indicates that, because of the disparity between the computer models and actual observations, the shrinking of summertime ice is about 30 years ahead of th...Mule deer moms rescue other fawns
... to defend it. As a result, whitetail fawns suffer considerably more predation during the first months of life than do mule deer fawns." Mule deer may have developed a more effective aggressive defence because they rely on fighting to protect themselves against predators year-round, while whitetails and many o...Brightening prospects of using fluorescent nanotubes in medical applications
...ve to ten times. The fact that the improvement was considerably larger – 20 to 100 times – came as a pleasant surprise. “Quantum efficiency is critical, but there are several other factors that make nanotubes particularly well suited for use in living systems,” says Hertel. These factors include: Nanotubes ...
