― IV drips can be left in place [physorg.com]
Small intravenous devices (IVDs) commonly used in the hand or arm do not need to be moved routinely every 3 days. A randomized controlled trial comparing regular relocation with relocation on clinical indication, published in the open access journal BMC Medicine, found that rates of complications were the same for both regimens.

― Researchers analyze impact of chemical BPA in dental sealants used in children [physorg.com]
Researchers from Mount Sinai School of Medicine have found that bisphenol A (BPA) released from some plastic resins used in pediatric dentistry is detectable in the saliva after placement in children's mouths. BPA is a widely used synthetic chemical that has been associated with changes in behavior, prostate and urinary tract development, and early onset of puberty. The findings are published in the current issue of Pediatrics.

― Flying fish glide as well as birds [physorg.com]
How well do flying fish fly? This is the question that puzzled Haecheon Choi from Seoul National University, Korea. Measuring aerodynamic forces on dried darkedged-wing flying fish in a wind tunnel, Choi and Hyungmin Park discovered that flying fish glide better than insects and as well as birds. The fish also derive an aerodynamic advantage from gliding close to the water's surface to cover distances as great as 400 meters.

― If Fine-Structure Constant Varies, Then The Laws Of Physics Throughout The Universe Do Too [science20.com]
What happens to the laws of physics if a fundamental constant turns out to be not a constant after all. The 'magic number' known as the fine-structure constant, called 'alpha' by physicists, appears to vary throughout the universe, according to a team of astrophysicists. That means the laws of physics would vary throughout the universe also. The preprint describes how one of the supposed fundamental constants of Nature appears not to be constant after all. Instead, this 'magic number'...

For the first time, a team of MIT chemical engineers has observed single ions marching through a tiny carbon-nanotube channel. Such channels could be used as extremely sensitive detectors or as part of a new water-desalination system. They could also allow scientists to study chemical reactions at the single-molecule level. Carbon nanotubes — tiny, hollow cylinders whose walls are lattices of carbon atoms — are about 10,000 times thinner than a human hair. Since their discovery nearly 20...
