Bioethics established itself in the late 1960s as a field concerned with the ethical and philosophical implications of certain biological and medical procedures, technologies, and treatments. Early issues included end-of-life decision-making, organ donation, and human experimentation. Human biotechnology became a concern when the first bioethics institutes were established in the early 1970s. This attention skyrocketed in 1990 when the U.S. Human Genome Project earmarked 3% to 5% of its $3 billion federal budget to the Ethical, Legal, and Social Implications (ELSI) research program, making its activities the world's largest bioethics program. Bioethics initially represented diverse ethical philosophies.
Lead is a highly toxic metal, whose neurotoxin has had sickening and deadly affect on humans for almost 3,000 years. And lead is still found in harmful quantities in a frighteningly large array of consumer products today. Why is such a toxic metal still in our products and in our homes?

Updated March 30, 2013 Page révisée le 30 mars 2013 [ Go to Canadian Social Research Links Home Page ] Statistics Canada cuts long data short: another longitudinal survey is cancelled http://milescorak.com/2012/06/18/statistics-canada-cuts-long-data-short-another-longitudinal-survey-is-cancelled/ June 18, 2012 The Survey of Labour and Income Dynamics died this morning. The notice was given quietly by Statistics Canada: “This is the last release of longitudinal data from the Survey of Labour and Income Dynamics. Effective with next year’s release of 2011 data, only cross-sectional estimates will be available.” [ http://goo.gl/gm5cT ] A short, simple, and slightly obtuse, statement of a profound change for the user community and Canadians in general.

La languette placée en état de superposition quantique. (O'Connell et al., Nature, Advance Online Publication) D e la physique quantique, oui, mais visible à l’œil nu! Andrew Cleland et son équipe de l’université de Californie ont réussi à placer une languette de métal de plusieurs dizaines de micromètres dans un état de superposition quantique.
It seems to be part of the job description of anyone in the sciences to periodically complain that scientific research funding is insufficient, with the situation going from bad to worse. For some recent examples, see this from Bruce Alberts, the Editor-in-Chief of Science, and this endorsement from Professor Matt Strassler. In the contrarian spirit of this blog, I want to suggest that the situation is actually quite a bit more complicated, and the story of research funding is not completely a one-sided one of the oppression and impoverishment of scientists.

Amyotrophic lateral sclerosis ( ALS ) – also referred to as motor neurone disease in some Commonwealth of Nations countries and as Lou Gehrig 's disease in the United States – is a debilitating disease with varied etiology characterized by rapidly progressive weakness, muscle atrophy and fasciculations , muscle spasticity , difficulty speaking ( dysarthria ), difficulty swallowing ( dysphagia ), and difficulty breathing ( dyspnea ). ALS is the most common of the five motor neuron diseases . [ edit ] Signs and symptoms The disorder causes muscle weakness and atrophy throughout the body caused by the degeneration of the upper and lower motor neurons . Unable to function, the muscles weaken and atrophy . Individuals affected by the disorder may ultimately lose the ability to initiate and control all voluntary movement, although bladder and bowel sphincters and the muscles responsible for eye movement are usually, but not always, spared until the terminal stages of the disease.

The critical discovery in this atomic model emerged a century ago in a talk before the Manchester Literary and Philosophical Society in March 1911 and a paper published soon after in the Philosophical Magazine. Both were by Ernest Rutherford, who had won the 1908 Nobel Prize in Chemistry in part for his discovery of the alpha particle, which he later proved was the nucleus of a helium atom. By 1911, scientists had already measured the charge and mass of an electron. But no one was sure how the atom was structured.
We like to feel superior to the people who lived centuries ago, what with their shitty mud huts and curing colds by drilling a hole in their skulls. But we have to give them credit: They left behind some artifacts that have left the smartest of modern scientists scratching their heads. For instance, you have the following enigmas that we believe were created for no other purpose than to fuck with future generations.
Prof. Robert Zoellner, with a model of the molecule created by ten year-old Clara Lazen I don't know about other people, but when I was a child, I was inventing things such as a musical instrument made out of a folded piece of cardboard and some rubber bands. Ten year-old Clara Lazen, however, has done something a little more noteworthy. The fifth-grader from Kansas City, Missouri, built a model of a molecule that is new to science. If the molecule itself were to actually be created, it could possibly be used for energy storage, or in explosives.
The more we understand about science and its complexities, the more important it is for scientific data to be shared openly. It’s not useful to have ten different labs doing the same research and not sharing their results; likewise, we’re much more likely to be able to pinpoint diseases if we have genomic data from a large pool of individuals. Since 2004, we’ve been focusing our efforts to expand the use of Creative Commons licenses to scientific and technical research.

Forensic Anthropology Forensic anthropology combines the theories and methods of anthropology, osteology and archaeology with legal investigations. The role of the forensic anthropologist can be varied, including aiding in the collection and analysis of human remains, the identification of victims beyond recognition, the estimation of time since death, and the establishment of injuries and potentially cause of death. The victims examined by anthropologists are usually in the late stages of decomposition, are completely skeletonised, or have been rendered otherwise unrecognisable by fire damage or other injuries. The forensic anthropologist will sometimes be called in when suspected human remains are first discovered to aid in the excavation and initial analysis of the bones. Following the careful excavation, documentation and collection of the remains, they are cleaned up in preparation for the analysis.
10 shops in a flat city and their Voronoi cells (larger version below ). In mathematics , a Voronoi diagram is a way of dividing space into a number of regions. A set of points (called seeds, sites, or generators) is specified beforehand and for each seed there will be a corresponding region consisting of all points closer to that seed than to any other. The regions are called Voronoi cells. It is dual to the Delaunay triangulation .
What's the Big Idea? The so-called "holy grail" of mathematics may have just been found. Shinichi Mochizuki , a professor at the Research Institute for Mathematical Sciences at Kyoto University, released a 500-page proof of the abc conjecture in number theory which involves the relationship between prime numbers, which I will attempt to describe as succinctly as possible below.
