...Oncologists are also excited about a new generation of tests that enable doctors to do a better job of matching the treatment to the tumor. Oncotype Dx, introduced in 2004, looks at 21 genes in biopsied tissue to determine whether or not chemotherapy will be helpful for early breast cancer patients with recent diagnoses. At Duke University, molecular geneticist Joseph Nevins is testing a similar gene-based test for lung cancer. Researchers are aiming for tools that will tell them not only whether chemo is needed but also which specific drugs to use. Such a screen already exists for Herceptin...
...across other AIM sectors, assessing overseas businesses from London can be like drilling for oil with a blindfold. That risk is particularly acute in emerging-markets companies. "The best way to test for integrity is to ask around," says Simon Cawkwell, an independent trader who's invested millions in AIM since its launch. But, he adds, "You can't ask around in China...
Basalt sequestration is one of several efforts to boost Iceland's role in climate-change science, including research into soil carbon sequestration and hydrogen-powered transportation. And Grimsson isn't above doing some firsthand testing. "I probably shouldn't tell you this, but I was the first person to exceed the speed limit in a hydrogen-powered car," he says. "I wanted to test its capability...
...Department of Energy is funding seven research partnerships to test sequestration technologies. This summer, one of those projects will inject a modest 2,000 metric tons of CO2 into the sandstone subsurface beneath a spread of tomato fields near Thornton, Calif., where it would stay, in effect, forever...
Many people would feel a lot better about psychiatry were there definitive tests for its catalog of disorders. For now, its practitioners make judgments on the basis of checklists and observation - solid methodology as far as it goes, but not the same as, say, a blood test for anaemia or an x-ray of a broken femur. In the search for a test offering this kind of diagnostic certainty in mental illness, two Australian researchers believe they've made a leap. Gin Malhi and Jim Lagopoulos, from the department of psychological medicine at Sydney's Royal North Shore Hospital, report...
