...were really frustrated with all these health rules and all these people who were getting stressed out trying to keep them. So we decided we would research them and find out the truth. We were surprised to find that most of them were based on very little - if any - data...
...doing a randomized [trial], where some people ate blueberries and some people ate raspberries? The second thing is, Was it in people or in rats or in Petri dishes? You want to look at how many people they studied. Obviously, the more people you study, the more accurate the data's going to be. And then, Who funded the study? It does seem that all the studies that are funded and published by the Blueberry Growers of America say you should eat blueberries...
...Extensive antiretroviral treatment can result in the development and transmission of drug-resistant strains of HIV - something the Lancet study did not consider. In the new study, published on Thursday, a team of scientists from the University of California, the University of Tennessee and the University of Ottawa analyzed data from San Francisco, where antiretroviral drugs have been extensively prescribed to HIV patients since AZT was introduced in 1987. In that city, drug resistance has grown steadily and, according to the team's models, drug-resistant infections are now on the verge of spiking. (See pictures of Africa's AIDS...
...paddies serve a similarly dual role for both CO2 and methane, acting as sources and sinks simultaneously. The challenge has been trying to tease out how those two functions balance out, but a new paper in the Jan. 14 issue of Science has provided some hard numbers. Using satellite data, investigators determined that wetlands contribute from 53% to 58% of global methane emissions and that rice paddies are responsible for more than a quarter of that output. The study could help make climate-change models more accurate, and help scientists understand whether increasing temperatures will lead to even higher methane...
...data Palmer and his colleagues used came from the Envisat satellite, launched by the European Space Agency, which gave them a rough picture of methane concentrations across the entire atmosphere. They then combined that with measurements from the multinational Gravity Recovery and Climate Experiment (GRACE) satellite, which gave them a broad estimate of planet-wide groundwater levels. Finally they added surface-temperature data from the U.S. National Center for Environmental Prediction/National CENTER for Atmospheric Research, because heat can increase methane emissions from wetlands as well.
