News of the Week
In science news around the world this week, Biosphere 2 launched a key watershed experiment, dengue fever has sickened more than 1300 people on Madeira, hunters have killed an estimated 10 wolves from Yellowstone National Park, the International Commission for the Conservation of Atlantic Tunas agreed to consider explicitly including shark conservation in its mandate, four more cases of a new coronavirus have been confirmed, a neurologist has been implicated in an insider trading case, the Atacama Large Millimeter/submillimeter Array has appointed French astronomer Pierre Cox as its new director, and European researchers still don't know how much money they will have to spend in the coming years.
Researchers in Austria have turned the eye of science on what makes a dahlia black, concluding that the black color comes from high levels of anthocyanins, the pigments that—at lower levels—also give orange and red dahlias their colors. In other news, a message to aliens that an MIT graduate student transcribed onto a metal disk last spring could outlast Earth itself. And this week's numbers quantify the drop in HIV infections since 2001 and the amount being committed to create a new drug research facility in Canada.
