AFP - The United States on Wednesday ordered oil and gas firms to permanently plug nearly 3,500 unused wells and dismantle hundreds of idle platforms in the Gulf of Mexico, in a bid to shore up industry safety after the disastrous BP...

Climate change: Can geoengineering satisfy everyone?

Reflecting sunlight from the Earth by geoengineering would undoubtedly cool the climate, but would different countries agree on how much to reflect? Research by climate scientists at the University of Bristol shows that the impact of geoengineering would be felt in very different ways across the world.

Does your insurance company know who the good doctors/surgeons are?

Several health plans have introduced physician rating systems to offer consumers more information when choosing their doctors. However, a recent study presented in the September issue of the Journal of Bone and Joint Surgery (JBJS) reveals that physician-tiering guidelines and results are not consistent across insurance companies, do not fully define quality; and could confuse consumers.

Nano research creates new products to market

Two new Arkansas start up companies have announced exclusive license agreements with UALR to bring to market patent-pending technology developed by the University`s Nanotechnology Center Research to provide anti-counterfeiting solutions for manufacturers.

Nerve cells use internal amplifiers to compensate for discrepancies in optic input

(PhysOrg.com) -- Generally speaking, animals and humans maintain their sense of balance in their three-dimensional environment without difficulty. In addition to the vestibular system, their navigation is often aided by the eyes. Every movement causes the environment to move past the eyes in a characteristic way. On the basis of this "optic flow", the nerve cells then calculate the organism's...

New supercomputer 'sees' well enough to drive a car someday (w/ Video)

(PhysOrg.com) -- Navigating our way down the street is something most of us take for granted; we seem to recognize cars, other people, trees and lampposts instantaneously and without much thought. In fact, visually interpreting our environment as quickly as we do is an astonishing feat requiring an enormous number of computations-which is just one reason that coming up with a computer-driven...

Scientists find genes related to body mass

Johns Hopkins scientists who specialize in unconventional hunts for genetic information outside nuclear DNA sequences have bagged a weighty quarry - 13 genes linked to human body mass. The experiments screened the so-called epigenome for key information that cells remember other than the DNA code itself and may have serious implications for preventing and treating obesity, the investigators say.
