Despite recent rumors that Facebook and FarmVille developer Zynga were gearing up for a legal battle, the two announced yesterday that they have signed a five-year agreement over how virtual currency will be used. Quoting: "The source of the conflict ... comes down to Facebook's decision to introduce Facebook Credits, an over-arching currency system to be used in all games on its platform. This allows users to purchase just one type of currency for use in Facebook games, rather than buying directly from individual developers — a lack of direct control over its monetization that became a major point of contention for Zynga. Also likely an issue is Facebook's decision to take 30 percent of revenues gathered from credits, with 70 percent allocated to the developers."

An anonymous reader writes "The organizers of the game Foldit, where you fold proteins for scientific research, announced that a user has found a protein that may be able to bind influenza viruses. Researchers plan to test the protein in a lab over the next few weeks to see if it might be medically useful."

ElectricSteve writes "Researchers have been searching for a highly targeted medical treatment that attacks cancer cells but leaves healthy tissue alone. The approach taken by scientists at Washington University in St. Louis is to use 'gold nanocages' that, when injected, selectively accumulate in tumors. When the tumors are later bathed in laser light, the surrounding tissue is barely warmed, but the nanocages convert light to heat, killing the malignant cells. ... Although the tumors took up enough gold nanocages to give them a black cast, only 6 percent of the injected particles accumulated at the tumor site. They would like that number to be closer to 40 percent so that fewer particles would have to be injected. They plan to attach tailor-made ligands to the nanocages that recognize and lock onto receptors on the surface of the tumor cells. ... The scientists at WUSTL have just received a five-year, $2.1M grant from the National Cancer Institute to continue their work with photothermal therapy."

Last year we discussed somewhat similar research using titanium dioxide nanoparticles to target a particular kind of brain cancer.

The South Australian Environment Department has told farmers that they should use poison gas or even explosives to deal with the out-of-control rabbit population. Commonwealth Scientific and Industrial Research Organization Invasive Animals chief Professor Tony Peacock, owner of the largest business card ever, says that blowing up rabbits isn't as inhuman as people might think, and has been ranked by the RSPCA as one of the best ways to destroy warrens.
