Substances produced in the body that act like those found in the cannabis plant help preserve bone density, according to researchers at the Hebrew University of Jerusalem. Based on this finding, a prototype for a new drug to prevent osteoporosis (loss of bone density) without any psychoactive side effects has already been developed.
An article describing this research appears this week in the prestigious American journal PNAS (Proceedings of the National Academy of Sciences of the U.S.A.). The researchers, from the Bone Laboratory of the Hebrew University, are headed by Prof. Itai Bab, working in cooperation with Prof. Esther Shohami of the Laboratory for the Study of Bain Trauma; Prof. Raphael Mechoulam of the Hebrew University School of Pharmacy; doctoral students Orr Ofek, Vardits Krem and Yossi Tam; and master’s degree student Meirav Fogel.
Substances made in the body called endocannabinoids are composed mainly of fatty acids which were discovered during the last 15 years. (The fatty acid anandamid was discovered by Prof. Mechoulam in 1992.) These materials, which are produced mainly in the brain, are present also in the bone and other tissues and have similar effects to those of the active components in hashish and marijuana, produced from the cannabis plant.

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...
