Biodiversity improves water quality in streams through a division of labor

ANN ARBOR, Mich.— Biologically diverse streams are better at cleaning up pollutants than less rich waterways, and a University of Michigan ecologist says he has uncovered the long-sought mechanism that explains why this is so.

Bradley Cardinale used 150 miniature model streams, which use recirculating water in flumes to mimic the variety of flow conditions found in natural streams. He grew between one and eight species of algae in each of the mini-streams, then measured each algae community’s ability to soak up nitrate, a nitrogen compound that is a nutrient pollutant of global concern.

*More Turkish Viewers Watch Online Video on Facebook Than YouTube*

London, UK, April 7, 2011 – comScore, Inc., a leader in measuring the digital world, today announced the launch of Video Metrix in Turkey. This online video measurement service, which was the first to market in the U.S. more than four years ago, has been developed to enable comScore’s clients to succeed in the online video marketplace. The debut Video Metrix report in Turkey showed that nearly 3 billion online videos were viewed by 20.2 million unique viewers in February 2011.

“At Nokta, we are firm believers in the value of transparency – not just to our business, but to the marketplace as a whole […],” says Tümay Asena, CEO at Nokta Medya. ”After a quick and easy tag implementation process, we are now looking forward to being able to showcase the full value of our video offering in ways that suit both the targeting needs of media planners, and the Nokta business model. The introduction of Video Metrix, comScore’s video measurement service, will make a true difference to the Turkish market.” (more…)

Berkeley Lab Researchers Create Next-Generation Chemical Mapping on the Nanoscale

A pixel is worth a thousand words? Not exactly how the saying goes, but in this case, it holds true: scientists at Berkeley Lab’s Molecular Foundry have pioneered a new chemical mapping method that provides unprecedented insight into materials at the nanoscale. Moving beyond traditional static imaging techniques, which provide a snapshot in time, these new maps will guide researchers in deciphering molecular chemistry and interactions at the nanoscale—critical for artificial photosynthesis, biofuels production and light-harvesting applications such as solar cells.

“This new technique allows us to capture very high-resolution images of nanomaterials with a huge amount of physical and chemical information at each pixel,” says Alexander Weber-Bargioni, a postdoctoral scholar in the Imaging and Manipulation of Nanostructures Facility at the Foundry. “Usually when you take an image, you just get a picture of what this material looks like, but nothing more. With our method, we can now gain information about the functionality of a nanostructure with rich detail.” (more…)

Did Obama’s Election Kill the Antiwar Movement?

ANN ARBOR, Mich.— Since 2003, the antiwar movement in the United States has had much to protest with Americans fighting in Iraq, Afghanistan and now Libya, but the movement—which has dropped off sharply the past two years—may be more anti-Republican than antiwar, says a University of Michigan researcher.

A new study by U-M’s Michael Heaney and colleague Fabio Rojas of Indiana University shows that the antiwar movement in the United States demobilized as Democrats, who had been motivated to participate by anti-Republican sentiments, withdrew from antiwar protests when the Democratic Party achieved electoral success, first with Congress in 2006 and then with the presidency in 2008.

Caterpillars that masquerade as twigs to avoid becoming a bird’s dinner are actually using clever behavioural strategies to outwit their predators, according to a new study. (more…)

Deflating Scientific Fallacies

Yale neurologist Steven Novella populates his podcasts and blogs with aliens, ghosts and creationists for a single purpose: to help resurrect the lost art of scientific thinking.

“I am interested in how otherwise intelligent people can get things so horribly wrong,” says Novella. In the process of answering that question he created the website Skeptics Guide to the Universe — which, with 150,000 listeners a week, is one of the 10 most popular science sites on the internet.

It might look like an abstract painting, but this splash of colors is in fact a busy star-forming complex called Rho Ophiuchi. NASA’s Wide-field Infrared Explorer, or WISE, captured the picturesque image of the region, which is one of the closest star-forming complexes to Earth. (more…)
