    Recycled tires could see new life in lithium-ion batteries that provide power to plug-in electric vehicles and store energy produced by wind and solar, say researchers. By modifying the microstructural characteristics of carbon black, a substance recovered from discarded tires, a team is developing a better anode for lithium-ion batteries.

  • Sens. John Boozman (R-Ark.) and James Inhofe (R-Okla.) predicted this week that lawmakers will find a new way to pay for U.S. transportation projects beyond the gas tax, according to the Fort Smith, Ark., Southwest Times Record...“Coming up between now and May, you’ll see a new funding mechanism that is going to change how we are funding our roads and highways,” Inhofe said, according to the report.

  • The cost of repairs and unfinished work on the $6.4 billion Bay Bridge eastern span is likely to exhaust what is left in the project's contingency fund for overruns, a Caltrans official warned Thursday. "We're trending in the wrong direction," Rich Foley, risk manager for the Caltrans toll bridge program, told the three-person committee that oversees the bridge project. "We are moving toward a cost overrun."

    It's become a given that ride services like Uber et al are disrupting city mobility, but for all the digital ink spilled over that trend, we don't have much data on what exactly the disruption looks like. (That is, other than the occasionally questionable data the services supply themselves.) So it's important for outside observers to pull the veil back a bit, and a research team at UC-Berkeley led by Lisa Rayle has done just that with a new working paper on "ridesourcing" services, as they're calling Uber, Lyft, Sidecar, and friends.

  • Michael Cassidy, a professor at UC Berkeley's Civil and Environmental Engineering department, has studied the phenomenon on Bay Area highways by carefully measuring freeway traffic with sensors and cameras..."Of all the maneuvers, it's probably the most disruptive to traffic," he said of the shenanigan. "If the police were to say, 'We're going to crack down on one type of maneuver,' that would be the one. It would likely have the most significant effect on traffic."

  • Lawmakers, Gov. Jerry Brown and ride-sharing companies have reached a deal on California legislation upping insurance requirements for the emerging companies such as Lyft and Uber...Both Uber and Lyft reversed course to support the bill, Lyft heralding a deal struck under the auspices of Brown and Senate leaders.

  • This week's big battle in the state Legislature was over AB2293, a bill that will require drivers for companies like Uber and Lyft to carry expanded insurance policies. The bill expands regulations that theCalifornia Public Utilities Commission has already begun: requiring drivers for these companies to carry commercial insurance coverage as soon as they log on to the phone applications that indicate they are available for driver services.

  • Massive savings to health-care spending can be had if governments implement a cap-and-trade carbon reduction program, say researchers at the Massachusetts Institute of Technology (MIT). In their study, the MIT researchers examined three types of carbon reduction policies in the U.S. and their effect on health-care spending and published their findings in the journal Nature Climate Change.

  • If "Goldilocks and the Three Bears" were written today, bike-share stations would play the role of the porridge. A station that's too full is a bad thing, because that means riders can't return a bike there. A station that's too empty is also a bad thing, because that means potential riders can't rent from there. To keep members happy, you need to get the number of bikes at a station just right.
