This isn't exactly the stamp of approval most scientists look for, though, and in this case the puffery is especially unfortunate because the actual scientific finding, described in a paper published on May 19 in the online journal PLoS One, really is important. First, the young mammal, which would have looked like a cross between a lemur and a small monkey, is astonishingly complete. "Most of what we understand about primate evolution is pieced together from bits of teeth and jaws," says Michael Novacek, curator of paleontology at the American Museum of Natural History. Ida, by contrast, has pretty...
...past few years, researchers have challenged the effectiveness of Prozac and other SSRIs in several studies. For instance, a review published in the Journal of Affective Disorders in February attributed 68% of the benefit from antidepressants to the placebo effect. Likewise, a paper published in PLoS Medicine a year earlier suggested that widely used SSRIs, including Prozac, Effexor and Paxil, offer no clinically significant benefit over placebos for patients with moderate or severe depression. Meanwhile, pharmaceutical companies maintain that their research shows that SSRIs are powerful weapons against depression. (Here's a helpful blog post that summarizes the debate...
...ecosystem. On Palmyra Atoll, 1,000 miles south of Hawaii, a population explosion of corallimorph, an aggressive creature similar to anemones and coral, killed almost all the coral growing around a long-line fishing vessel that sank in 1991, according to a report published in August in the journal PLoS One by Thierry Work, a wildlife-disease specialist at the U.S. Geological Survey, and his colleagues. The corallimorph were probably attracted to the leaching iron, a valuable nutrient in the sea, says Work. Since the organism, which sparsely populates other parts of the reef, grows fast, is aggressive and reproduces...
...Netherlands, with its permissive marijuana laws, may be known as the cannabis capital of the world. But a survey published this month in PLoS Medicine, a journal of the Public Library of Science, suggests that the Dutch don't actually experiment with pot as much as one would expect. Despite tougher drug policies in the U.S., Americans were twice as likely to have tried marijuana than the Dutch, according to the survey. In fact, Americans were more likely to have tried marijuana or cocaine than people in any of the 16 other countries, including France, Spain, South Africa, Mexico...
...only data set we have that is not biased." He points out that currently, researchers are not compelled to produce all results to an independent body once the drugs have been approved; but until they are, they must hand over all data. For that reason, while the PLoS Medicine paper data may not be perfect, it may still be among the best...
