Drug users are well informed about the harms associated with the drugs they use, and perceive alcohol and tobacco to be amongst the most dangerous substances, according to a survey by UCL (University College London) and Imperial College London researchers. The findings, published in the Journal of Psychopharmacology, suggest that the current system of classifying psychoactive drugs in the UK may need to be revisited. http://www.physorg.com/news178315435.html Medicine & Health Tue, 24 Nov 2009 20:30:01 EST news178315435 Haze in the early Earth atmosphere could have played a crucial role in the origin of life. By forming a protective shield, the haze would have safeguarded organic substances from harmful ultraviolet (UV) radiation. http://www.physorg.com/news174587577.html Space & Earth Mon, 12 Oct 2009 18:00:01 EST news174587577 (PhysOrg.com) -- Tracking down new active agents for cancer or malaria treatment could soon become easier - thanks to a computer program with which researchers from the Max Planck Institute of Molecular Physiology in Dortmund aim to facilitate the search for suitable pharmaceutical substances. The program, which is called Scaffold Hunter, acts as a tool for navigating chemical space. http://www.physorg.com/news167924736.html Chemistry Mon, 27 Jul 2009 15:30:02 EST news167924736 A new study shows that an alpha-particle emitting radiopeptide -radioactive material bound to a synthetic peptide, a component of protein -is effective for treating prostate cancer in mice, according to researchers. The results could eventually result in a significant breakthrough in prostate cancer treatment, especially for patients whose cancer recurs after the prostate is removed. http://www.physorg.com/news164292070.html Medicine & Health Mon, 15 Jun 2009 13:41:29 EST news164292070 New research documents a surprising chemical weapon used by some Amazonian poison frogs. The study identified for the first time a family of poisons never before known to exist in these brightly colored creatures or elsewhere in Nature, the N-methyldecahydroquinolines. The authors then speculated on its origin in the frogs` diet, most likely ants. The report is scheduled for the June 26 issue of ACS` Journal of Natural Products. http://www.physorg.com/news163350366.html Chemistry Thu, 04 Jun 2009 16:06:34 EST news163350366 A Canadian nuclear reactor that produced about a third of the world's supply of medical isotopes has halted operation for three months due to a heavy water leak, authorities said. http://www.physorg.com/news162708897.html Medicine & Health Thu, 28 May 2009 05:55:18 EST news162708897 Scientists in Washington State are reporting the first discovery of potent mutagenic substances in smoke from forest fires that often sweep through huge stands of Ponderosa pine in the western United States and Canada. http://www.physorg.com/news160233080.html Space & Earth Wed, 29 Apr 2009 14:11:38 EST news160233080 Veterinarians frequently suffer psychosocial stress and demoralization associated with heavy workloads. Research published in BioMed Central's open access Journal of Occupational Medicine and Toxicology analyses the extent of the problem and reveals a complex relationship with binge drinking, tobacco consumption and drug use. http://www.physorg.com/news154767300.html Medicine & Health Wed, 25 Feb 2009 06:55:47 EST news154767300 For airline passengers everywhere, good news. Scientists have successfully tested a liquid explosive detection system that may eventually keep dangerous substances off airplanes. This comes barely two years after a plot to make bombs out of liquids aboard planes taking off from London was foiled. http://www.physorg.com/news153054607.html Technology Thu, 05 Feb 2009 11:10:44 EST news153054607 The Canadian government reportedly is planning to release in February the world's first national regulation requiring companies to detail their use of engineered nanomaterials, according to environmental officials. The information gathered under the requirement will be used to evaluate the risks of engineered nanomaterials and will help to develop appropriate safety measures to protect human health and the environment. http://www.physorg.com/news152377937.html Nanotechnology Wed, 28 Jan 2009 15:12:52 EST news152377937 A research group from Sweden investigated the mechanisms underlying the reduction in gastric blood flow induced by a luminal water extract of Helicobacter pylori (H. pylori). They found that the H. pylori water extract reduces gastric mucosal blood flow acutely through iNOS- and nerve-mediated pathways. http://www.physorg.com/news151754929.html Medicine & Health Wed, 21 Jan 2009 10:09:20 EST news151754929 (PhysOrg.com) -- A team of medical scientists from the University of Leicester has published research which looks into the harmful substances in liquid medicines that premature babies are being exposed to. http://www.physorg.com/news151592061.html Medicine & Health Mon, 19 Jan 2009 19:00:01 EST news151592061 Substances in marijuana show promise for fighting deadly drug-resistant bacterial infections, including so-called "superbugs," without causing the drug's mood-altering effects, scientists in Italy and the United Kingdom are reporting. http://www.physorg.com/news140112587.html Chemistry Mon, 08 Sep 2008 17:09:47 EST news140112587 That evocative "earthy" scent of the soil returning to life in spring - and nasty earthy tastes and odors in fish and drinking water - actually results from two substances released by soil bacteria. Researchers in Rhode Island now report identifying how one of these substances forms, an understanding that could lead to improvements in the quality of water and food products. Their study, the first substantial research on the topic in 30 years, is scheduled for the July 23 issue of the weekly Journal of the American Chemical Society. http://www.physorg.com/news135869154.html Chemistry Mon, 21 Jul 2008 14:25:54 EST news135869154
