“Surprisingly, some of the catalysts we’ve developed for use in the artificial leaf device actually heal themselves” Another innovative feature has been added to the world’s first practical “artificial leaf,” making the device even more suitable for providing people in developing countries and remote areas with electricity, scientists reported here today. It gives the leaf

ON Tuesday, Denny Chin, a federal judge in Manhattan, rejected the settlement between Google, which aims to digitize every book ever published, and a group of authors and publishers who had sued the company for copyright infringement. This decision is a victory for the public good, preventing one company from monopolizing access to our common cultural

Four days later, Chris woke up   The moment she saw him, Judy Cox knew her son was dead. It was an October morning in 2008, and she had just stepped out the door to run an errand when she found him lying faceup in the driveway, ghost white, covered in purple splotches. He wasn’t

A recent study by scientists from NUS revealed that the current biodiversity crisis may be much broader than widely assumed, and may affect even species thought to be common and tolerant of fragmentation and habitat loss. Specifically, the research team found that the effective population size and genetic diversity of a common fruit bat species — the

New Berkeley Lab analysis simulates fleet of self-driving taxis in Manhattan It may be only a matter of time before urban dwellers can hail a self-driving taxi, so researchers at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and UC Berkeley decided to analyze the cost, energy, and environmental implications of a fleet

“If localized drug delivery is an important goal, then nanospheres will fail” Many medically minded researchers are in hot pursuit of designs that will allow drug-carrying nanoparticles to navigate tissues and the interiors of cells, but University of Michigan engineers have discovered that these particles have another hurdle to overcome: escaping the bloodstream. Drug delivery

You know it when it happens: All of a sudden, everyone on the Internet is talking about the same thing. What does it mean for the future of information? Last month, over a billion people around the world suddenly knew the name and appearance of the very same woman, and simultaneously began exchanging opinions about

Physicists say they can make money that can’t be copied—at least in theory   Since the invention of paper money, counterfeiters have churned out fake bills. Some of their handiwork, created with high-tech inks, papers, and printing presses, is so good that it’s very difficult to distinguish from the real thing. National banks combat the

Their discovery has profound significance for dermatology. A research team at Karolinska Institutet in Sweden has succeeded in describing the structure and function of the outermost layer of the skin — the stratum corneum — at a molecular level. This opens the way not only for the large-scale delivery of drugs via the skin, but

New technology from Pittsburgh, Pennsylvania startup Dynamics Inc. could help cut the number of cards
