Benefits of non-drug techniques top most popular sleeping pill, Ambien
A study by researchers at Beth Israel Deaconess Medical Center (BIDMC) and Harvard Medical School has found cognitive behavioral therapy (CBT) is more effective than sleeping pills in treating chronic sleep-onset insomnia. The findings, which appear in the Sept. 27 issue of the Archives of Internal Medicine, show non-drug techniques yield better short and long-term results than the most widely prescribed sleeping pill, zolpidem, commonly known as Ambien. It is the first placebo-controlled trial to evaluate the separate and combined effects of CBT and pharmacological therapies in treating insomnia in young and middle-aged adults.
"Sleeping pills are the most frequent treatment for insomnia, yet, CBT techniques clearly were more successful in helping the majority of study participants to become normal sleepers. The pills were found to be only moderately effective compared to CBT and lost their effectiveness as soon as they were discontinued," said study leader Gregg Jacobs, Ph.D., insomnia specialist in the Sleep Disorders Center of BIDMC and an assistant professor of psychiatry at Harvard Medical School. "Our results suggest CBT should now be considered the first line treatment for insomnia, which is experienced on a nightly basis by one-third of the nations adult population," added Jacobs.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
