Tobacco, used on a small scale as a natural organic pesticide for hundreds of years, is getting new scientific attention as a potential mass-produced alternative to traditional commercial pesticides. That's the topic of a report in ACS' bi-weekly journal Industrial & Engineering Chemistry Research.

Richmond, Va. (Oct. 27, 2010) – If you were dying from cancer, would you consider genetic testing? A recent study conducted by researchers from Virginia Commonwealth University Massey Cancer Center showed that most terminally ill cancer patients who were eligible for genetic testing never received it despite that it could potentially save a relative's life.
Quebec City, October 27, 2010—High doses or prolonged use of glucosamine causes the death of pancreatic cells and could increase the risk of developing diabetes, according to a team of researchers at Université Laval's Faculty of Pharmacy. Details of this discovery were recently published on the website of the Journal of Endocrinology.
VICTORIA – Industrial-scale aquaculture production magnifies environmental degradation, according to the first global assessment of the effects of marine finfish aquaculture (e.g. salmon, cod, turbot and grouper) released today. This is true even when farming operations implement the best current marine fish farming practices.
Dr. John Volpe and his team at the University of Victoria developed the Global Aquaculture Performance Index (GAPI), an unprecedented system for objectively measuring the environmental performance of fish farming.
When it comes to understanding where tendencies to overweight and obesity develop, you have to begin with the very young, says John Spence, a behavioural scientist in the Faculty of Physical Education and Recreation at the University of Alberta.
His research, the first of its kind to look at North American kids and published in the International Journal of Pediatric Obesity, examined four- and five year olds' avoidance or approach behaviours to food and their relationship with body weight.
An international team of primatologists have discovered a new species of monkey in Northern Myanmar (formerly Burma.) The research, published in the American Journal of Primatology, reveals how Rhinopithecus strykeri, a species of snub-nosed monkey, has an upturned nose which causes it to sneeze when it rains.
Nagoya, Japan, Wednesday 27 October 2010 (IUCN) – The most comprehensive assessment of the world's vertebrates confirms an extinction crisis with one-fifth of species threatened. However, the situation would be worse were it not for current global conservation efforts, according to a study launched today at the 10th Conference of the Parties to the Convention on Biological Diversity, CBD, in Nagoya, Japan.
A new analysis of several major global studies of future species shifts and losses foresees inevitable continuing decline of biodiversity during the 21st century but offers new hope that it could be slowed if emerging policy choices are pursued.
Increasing numbers of birds, mammals and amphibians have moved closer to extinction in the last several decades—but not as far as they would have if no conservation measures at all had been enacted, researchers report.
Their study is being published online by the journal Science, at the Science Express Web site, at 6:30 p.m., U.S. Eastern Time, Tuesday, 26 October. Science is the journal of AAAS, the nonprofit science society.
Dr. Jack Musick, emeritus professor at the Virginia Institute of Marine Science, has overseen a global study suggesting that 33 percent of shark, skate, and ray species are threatened with extinction.
Journals need to develop policies to handle the inevitable competing interests that arise when they publish papers that may bring them reprint revenue or increase their impact factors. This is the conclusion of a research article by Andreas Lundh and colleagues from the Nordic Cochrane Centre published in this weeks PLoS Medicine.
Current WHO pesticide classifications are based on toxicity in rats but basing regulation on human toxicity will make pesticide poisoning less hazardous and prevent hundreds of thousands of deaths globally without compromising agricultural needs. These are the key findings from a study by Andrew Dawson (South Asian Clinical Toxicology Research Collaboration, University of Peradeniya, Sri Lanka) and colleagues published in this week's PLoS Medicine.
Montreal −If you are a person who already has stable heart disease, how fast your heart beats at rest can predict your risk of dying, not only from heart disease but all other causes, Dr. Eva Lonn told the Canadian Cardiovascular Congress 2010, co-hosted by the Heart and Stroke Foundation and the Canadian Cardiovascular Society.
"The higher the heart rate, the higher the risk of death from cardiovascular and all causes, even after adjusting for all risk factors that could confound our results," says Dr. Lonn, a cardiologist and professor at McMaster University.
