...lack the advanced lab resources to culture TB samples, they test for TB by smear microscopy - a laborious and often ineffective process in which a patient coughs up some sputum and a technician looks at the sample under a microscope, trying to pick out the bacteria by eye. That method "is very good at finding people who are infectious," says Liz Corbett, a clinical researcher from the London School of Hygiene and Tropical Medicine who works with TB patients in Zimbabwe. But a patient can have active, even lethal, TB without being very infectious. Using the standard smear-microscopy method...
...researchers still need to fine-tune their technology so it can be mass-produced cheaply. They also need a better method for treating sputum so it's ready for GCMS analysis. In 2009, Corbett will run a preliminary trial for them with 1,200 Zimbabweans suspected of having TB. If that evaluation goes well, the Wellcome Trust has said it will find a company to mass-produce the machine...
...silhouette strategy for planet hunting will not replace the wobble-watching method. Indeed, red dwarfs make that method easier and faster. "M-dwarf stars are small," says astronomer Geoff Marcy of UC Berkeley, one of the discoverers of 55 Cancri's newfound planet. "That means planets can kick them around more easily." And all that means the first twin of Earth might really be found before long--and the discovery of life on other worlds could get a whole lot closer. The 55 Cancri Family of Planets [This article contains a complex diagram. Please see hardcopy of magazine.] A SIMILIAR...
Instead, Petersen said that the user might have been downloading articles for “text-mining,” a research method that uses complex natural language processing to extract information from, and identify patterns in, large aggregations of text...
...Genotek's main customers are medical researchers, Big Pharma companies developing drugs that can be tailored to individuals, and researchers involved in large genetic studies. Chaim Birnboim, a research scientist and med-school professor who developed Oragene, knew there was demand for a simple, noninvasive DNA-collection method, "and I thought, I can do that." The trick was discovering that saliva was a rich source of DNA that could be easily stabilized. The product could have important implications for law enforcement, forensic sciences and the military. Individuals may even want an Oragene kit to preserve a bit of a loved...
