Legal highs flooding UK pose immense overdose risk, warns drugs tsar
Users face growing threat from 200-plus synthetic drugs in circulation across UK, says government's chief drugs adviserThe chief drugs adviser to the government has given his strongest warning yet on legal highs in Britain, saying there are now more than 200 synthetic psychoactive drugs being sold outside existing laws.Prof Les Iversen warned of the arrival of a new generation of compounds that imitate the effects of 1960s-style LSD psychedelics and cautioned that they could bring with them serious risk of overdose.Iversen, the chairman of the home secretary's advisory council on the misuse of drugs (ACMD), said these unte...

Joe Farman obituary
Scientist whose discovery of the depletion of the ozone layer sparked global action to phase out dangerous chemicalsJoe Farman, who has died aged 82, was the leader of a small group of scientists who made one of the most important discoveries in recent history. In 1985, they published a landmark paper on the ozone layer, the protective skin that filters the sun's ultraviolet rays and without which the rays can cause cancers and eye damage. Their research showed that the ozone layer was being rapidly depleted over the Antarctic.Just two years later, world governments signed the Montreal protocol, a treaty phasing out the us...

Chemists Demonstrate Nanoscale Alloys So Bright They Could Have Potential Medical Applications
Alloys like bronze and steel have been transformational for centuries, yielding top-of-the-line machines necessary for industry. As scientists move toward nanotechnology, however, the focus has shifted toward creating alloys at the nanometer scale - producing materials with properties unlike their predecessors. Now, research at the University of Pittsburgh demonstrates that nanometer-scale alloys possess the ability to emit light so bright they could have potential applications in medicine. The findings have been published in the Journal of the American Chemical Society... (Source: Health News from Medical News Today)

Natural 'keystone molecules' punch over their weight in ecosystems
(American Institute of Biological Sciences) Ecosystems are disproportionately influenced by "keystone molecules" that have powerful behavioral effects and contribute to ecosystem structure, according to a general theory described in the June issue of BioScience. The chemicals can each fill a variety of functions and affect multiple species. The actions of four keystone molecules are described, three of them toxins. (Source: EurekAlert! - Medicine and Health)

Vicious cycle: Obesity sustained by changes in brain biochemistry
(Brown University) In a new discovery reported in the Journal of Biological Chemistry, Brown University and Lifespan researchers show that in the brain cells of rats, obesity impedes the production of a hormone that curbs appetite and inspires calorie burning. The root cause appears to be a breakdown in the protein-processing mechanism of the cells. In the lab, the researchers showed they could fix the breakdown with drugs.

Jekyll into Hyde: Breathing auto emissions turns HDL cholesterol from 'good' to 'bad'
Academic researchers have found that breathing motor vehicle emissions triggers a change in high-density lipoprotein (HDL) cholesterol, altering its cardiovascular protective qualities so that it actually contributes to clogged arteries.
In addition to changing HDL from "good" to "bad," the inhalation of emissions activates other components of oxidation, the early cell and tissue damage that causes inflammation, leading to hardening of the arteries, according to the research team, which included scientists from UCLA and other institutions.
The findings of this early study, done in mice, are available in...

The UK's first anti-ageing fair: not all Botox and miracle fillers
Yes there was a barrage of waffle, loads of buzz-words and some 'miracle' treatments on offer – but good advice on offer tooDo you remember a time before anyone coined the term "anti-ageing"; a time when the most a beauty regime consisted of was slapping on some Pond's and a couple of cucumber slices? I don't like "anti-ageing". It's a wrong-headed term that manages to be both negative and misleading – as though the act of ageing represents some kind of personal failure. I appreciate it's catchy from a marketing point of view but can we not be a bit more honest, please? I love a new beauty treatment as much as the next...

How Much A Single Cell Breathes
Scanning electrochemical microscopy decisively optimized How active a living cell is can be seen by its oxygen consumption. The method for determining this consumption has now been significantly improved by chemists in Bochum. The problem up to now was that the measuring electrode altered the oxygen consumption in the cell's environment much more than the cell itself. "We already found that out twelve years ago," says Prof. Dr. Wolfgang Schuhmann from the Department of Analytical Chemistry at the Ruhr-Universitat. "Now we have finally managed to make the measuring electrode an spectator... (Source: Health News from Medical News Today)

No proof that red hair raises skin cancer risk
Conclusion
The researchers' article discusses potential ways in which the red pigment found in the cells of people with red hair might increase the risk of melanoma, the most serious form of skin cancer. It is not a standard report of a research study, but the authors put forward potential explanations for their previous research findings. These now need to be tested to see if they are correct.
The researchers' previous research found that mice genetically engineered to be predisposed to melanoma and red fur developed melanomas even without UV exposure. It is not clear to what extent these genetically engineered mice rep...

A large, multi-institutional research team involved in the NIH Epigenome Roadmap Project has published a sweeping analysis in the current issue of the journal Cell on how genes are turned on and off to direct early human development. Led by Bing Ren of the Ludwig Institute for Cancer Research, Joseph Ecker of The Salk Institute for Biological Studies and James Thomson of the Morgridge Institute for Research, the scientists also describe novel genetic phenomena likely to play a pivotal role not only in the genesis of the embryo, but that of cancer as well...
