FDA sees nanotech challenges in every product category it regulates

... in the Task Force report, FDA will not be able to keep pace with today’s rapidly developing nanotechnology market or engender consumer and investor confidence in emerging products.” Just released, this is the first report from the Food and Drug Administration’s Nanotechnology Task Force about the agency...

Longer treatment benefits sleep apnea patients

... works by blowing just enough air into the nose to keep the patient's throat open. Because they often find the CPAP device cumbersome, many patients do not use it consistently or for long enough periods while sleeping. In the current study, for example, patients used CPAP on average about 5 hours a n...

ASU research shows connection between testosterone, dietary antioxidants and bird coloration

...e immune costs of testosterone elevation and still keep their attractive and bright colors,” McGraw said. Most previous studies of this sort have focused on physiological or even genetic links between testosterone and health. He adds that it is worth considering the implications for human nutrition and he...

Study investigates 'divorce' among Galapagos seabirds

...eing a devoted husband and father is not enough to keep an avian marriage together for the Nazca booby, a long-lived seabird found in the Galapagos Islands off the coast of Ecuador. Many Nazca booby females switch mates after successfully raising a chick, according to a Wake Forest University study sched...

Reconstructing the biology of extinct species: A new approach

...triggering the neck and eye muscles to reflexively keep the visual image stable. The basic hypothesis of the project was that the organ of balance -- which helps stabilize an animal's gaze and coordinate its movements as it travels through the environment -- should be irrevocably linked to the type o...

Study identifies 5 genetic themes key to keeping stem cells in a primitive, flexible state

...ording to this research, stem cells are cells that keep their DNA packaged in a flexible format, keep cell division tightly controlled, prevent signals that might trigger death, repair DNA very effectiv...

How brain pacemakers erase diseased messages

... stimulation delivered at too slow a pace fails to keep bad information at bay. Indeed, slower pulses can actually add to problematic bursts, they showed. The model's findings closely parallel the clinical responses of patients, who typically experience the greatest relief from symptoms when their devi...

Lessons from the orangutans: Upright walking may have begun in the trees

Technique monitors thousands of molecules simultaneously

...eaction at only electrodes that were turned on. To keep the palladium(II) from going to a neighboring electrode a second reagent was added to the solution above the chip that destroyed the palladium(II) reagent. In this way, nothing happened at electrodes that were not being used. Reversing the polarit...

'Insulator' helps silence genes in dormant herpes virus

...tists have long puzzled over the mechanism used to keep this small region of the genome going while nearby genes remain quiescent. Now, scientists at The Wistar Institute have discovered a molecular mechanism that keeps HSV-1 activation restricted to a single gene for months or even years. The research...

The carbon nanotubes are extremely long compared to predecessors--the lo...

Sleepless for science: Flies show link between sleep, immune system in Stanford study

...to it so they could nap." Another option was to keep the flies in continuous light. But Schneider and Shirasu-Hiza decided that an even better way would be to turn to established fly strains isolated decades ago that possess disruptions in their genes controlling circadian rhythm. In this case, these m...
