The world’s largest study of ecstasy-related deaths discovered that one in six people who died after taking ecstasy had not taken any other drug. “This clears up the debate once and for all – ecstasy alone can kill,” says Dr Fabrizio Schifano, whose work is published in the October edition of Human Psychopharmacology.
The study found that since 1996 there had been a clear year-on-year increase in deaths in England and Wales. “Just show anyone the graph and the message is clear – the situation is getting worse,” says Dr. Schifano, who works at the National Programme on Substance Abuse Deaths at St George’s Hospital Medical School, London. There were 12 deaths in 1996 and 1997; 26 in 1998; 40 in 1999; 52 in 2000 and 72 in 2001-2.
Dr. Schifano is also alarmed that so many of the victims are so young. Three quarters were below the age of 29 and 1 in 7 were younger than 19. On top of this, four out of five victims were male. These results paint a clear and alarming picture of increased risk for men between the age of 16 and 24.

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...
