Public release date: 11-Sep-2012 [ Print | E-mail Share ] [ Close Window ] Contact: Rachel Feldmanrfeldman@univ.haifa.ac.il 972-482-88722University of Haifa "The most important thing for us is to raise awareness of the dangers of artificial light at night and we have already come a long way now that the American Medical Association (AMA) recently announced its new policy recognizing adverse health effects of exposure to light at night and encouraging further research into the matter," said Prof.
Light Pollution May Be Dangerous: DNews Nugget. The Dangers of Light Pollution: Light pollution might seem an annoyance when trying to look at stars, but there are deeper dangers to that nightly glow.
Insects, plants and humans all depend on a nightly cycle. When that cycle is removed or altered, the rhythms of nature are affected. This alteration can increase illness, affect hormone production, body mass and even oxygen consumption. The American Medical Association (AMA) plans to study the "adverse health effects of exposure to light at night and encouraging further research into the matter," reports Phys.org. Welsh farmer leads anti-GM crop protest against pioneering wheat crop experiment. A West Wales farmer is leading calls against “irresponsible” and “negligent” genetically-modified (GM) crop research which could one day reduce pesticide use on agricultural land.

New Fatal Bird-Flu Virus Appears in Viet Nam. Poultry News New Fatal Bird-Flu Virus Appears in Viet Nam 12 September 2012 VIET NAM - A new highly-toxic avian flu virus, which can kill humans, is quickly spreading in northern and central Viet Nam, reported the National steering board for bird flu and foot-and-mouth disease prevention.
The acting head of the Veterinary Agency, Mr Hoang Van Nam, said the new virus still belongs to the 2.3.2.1 virus branch but it is different from the 2.3.2.1 virus (both A and B groups,) which caused the avian flu epidemic in Viet Nam last year. Mr Nam said that this virus can make the avian flu epidemic to spread widely in Viet Nam in the coming time. Hunting Practice Helps Spread Bird Flu. 'If you want red squirrels, you have to kill greys' A red squirrel at Trewithin Gardens, Cornwall.

Greys also carry a squirrelpox to which they are immune but which condemns reds to a lingering myxomatosis-like death within a fortnight. Scottish Natural Heritage, which has chipped in £7,000, says greys replace reds within 15 years of reaching an area – and 20 times more quickly if they carry the pox. There are now 2.5 million greys in the UK and the 160,000 reds have been squeezed to the outer edges – the Isle of Wight, Brownsea Island, Formby, Cumbria, Northumberland and the last real stronghold, Scotland.

Americans and Europeans have been slathering triclosan on ever since hospitals began using it in antibacterial soaps and sanitizers 40 years ago.
But that era may be passing, especially after the release this week of a University of California, Davis and University of Colorado study showing that the widely used chemical impairs muscle functions, including the heart.

Detection and quantitative analysis of 21 veterinary drugs in river water using high-pressure liquid chromatography coupled to tandem mass spectrometry.
Introduction The use of veterinary drugs in food production focuses on the control and improvement of animal health.
The disadvantage of this practice is that pharmaceuticals and their metabolites are released into the environment, finding their way to natural water systems and becoming a potential risk to non-target organism. Methods This paper reports the development and validation of a quantitative method, based on high-performance liquid chromatography coupled to tandem mass spectrometry, for the simultaneous analysis of 21 veterinary drugs, antimicrobials, corticosteroids, coccidiostats and antifungal agents, in surface water. Results. Antibiotic Resistance Spreads Through Environment, Threatens Modern Medicine.
Waste from people, pets, pigs and even seagulls may be playing a significant role in the rise of antibiotic-resistant infections, including methicillin-resistant Staphylococcus aureus (MRSA), a number of new studies warn.
Widespread fear of diminishing returns for modern medicine is becoming amplified, scientists say, by the discovery of soils and waterways polluted with both traces of antibiotics and bacteria encoded with antibiotic-resistant genes, the information that tells a microbe how to evade drugs designed to kill it. And even if that fortified microbe isn't capable of causing illness in humans itself, scientists add, its DNA could find its way into the more malignant microbes in the environment. Scottish fish farmers use record amounts of parasite pesticides. Scottish fish farmers have been forced to use record amounts of highly toxic pesticides to combat underwater parasites that prey on salmon, raising fears of significant damage to the marine environment.
