Cooling the Planet With a Bubble Bath 219

cremeglace writes "A Harvard University physicist has come up with a new way to cool parts of the planet: pump vast swarms of tiny bubbles into the sea to increase its reflectivity and lower water temperatures. 'Since water covers most of the earth, don't dim the sun,' says the scientist, Russell Seitz, speaking from an international meeting on geoengineering research. 'Brighten the water.' From ScienceNOW: 'Computer simulations show that tiny bubbles could have a profound cooling effect. Using a model that simulates how light, water, and air interact, Seitz found that microbubbles could double the reflectivity of water at a concentration of only one part per million by volume. When Seitz plugged that data into a climate model, he found that the microbubble strategy could cool the planet by up to 3C. He has submitted a paper on the concept he calls “Bright Water" to the journal Climatic Change.'"

Political Affiliation Can Be Differentiated By Appearance 262

quaith writes "It's not the way they dress, but the appearance of their face. A study published in PLoS One by Nicholas O. Rule and Nalini Ambady of Tufts University used closely cropped greyscale photos of people's faces, standardized for size. Undergrads were asked to categorize each person as either a Democrat or Republican. In the first study, students were able to differentiate Republican from Democrat senate candidates. In the second, students were able to differentiate the political affiliation of other college students. Accuracy in both studies was about 60% — not perfect, but way better than chance."

Game Developers Note Net Neutrality Concerns To FCC 74

eldavojohn writes "A list of notes from game developers (PDF) was sent in a letter to the FCC which represented a net neutrality discussion between the developers and FCC representatives. Game Politics sums it up nicely, but the surprise is that developers are concerned with latency, not bandwidth, unlike the members of many other net neutrality discussions. One concern is that each and every game developer will need to negotiate with each and every ISP to ensure their traffic achieves acceptable levels of latency for users. 'Mr. Dyl of Turbine stated that ISPs sometimes block traffic from online gaming providers, for reasons that are not clear, but they do not necessarily continue those blocks if they are contacted. He recalled Turbine having to call ISPs that had detected the high UDP traffic from Turbine, and had apparently decided to block the traffic and wait to see who complained.' It seems a lot of the net neutrality discussions have only worried about one part of the problem — Netflix, YouTube and P2P — while an equally important source of concern went unnoticed: latency in online games."

Yellowstone Supervolcano Larger Than First Thought 451

drewtheman writes "New studies of the plumbing that feeds the Yellowstone supervolcano in Wyoming's Yellowstone National Park shows the plume and the magma chamber under the volcano are larger than first thought and contradicts claims that only shallow hot rock exists. University of Utah research professor of geophysics Robert Smith led four separate studies that verify a plume of hot and molten rock at least 410 miles deep that rises at an angle from the northwest."
