Bacteria Can Produce Plastic

| | Comments (0)

Not all of the fossil fuel we use goes to power our cars or heat our homes: Some is used to make plastic. The Discovery Channel tells us that researchers at Genomatica, a company in San Diego, CA, say they've developed bacteria that make an important ingredient of the plastic that's used in products from Spandex to car bumpers. The company says it can go into production as early as next year, and that its product will be cheaper even if the cost of oil drops as low as $50 a barrel.

The child of a science writer I know once hopped into her mother's lap and took control of the family computer. My friend was amazed to watch her daughter, who was 3 at the time, use the wheel on the mouse to scroll down the screen. "Oh," the science writer said, "that's what that does!"

Perhaps John McCain has felt just that kind of wonderment this year, as his staff and family have taught the 72-year-old Arizona senator how to browse the Web and read his daughter Meghan's campaign blog. The Republican nominee has described himself as a technological "Neanderthal" and computer "illiterate." And now his Democratic opponent has turned those comments into a campaign ad that paints McCain as "out of touch."

As satellite imagery and aerial photography have become more accessible, state and local governments are finding multiple uses for them in areas that include disaster response, law enforcement, transportation and urban planning.

Computer chips have become more powerful by cramming more and smaller transistors into the same space, and the industry right now is moving from technology where the key size measurement is 65 nanometers to 45-nanometer technology. But as CNET News reports, IBM is looking a couple technology generations ahead, to 22-nanometer devices. The challenge they're tackling: Technology to produce such small features doesn't yet exist, and it's not obvious how to create it.

Worried that the transition to digital television will result in a nationwide dumping of lead-laden analog TV sets early next year, environmentalists pushing for a response are beginning to gain traction in Congress. But the attention from lawmakers may be too late to limit damage.

Two resolutions (S Res 663 and H Res 1395) calling for the United States to join other nations in banning the export of electronic waste to developing countries have been introduced. But even if enacted, they would have little or no legal impact. The prospects for any other substantial congressional action in the short term are dim.

The effort to provide free WiFi connections for low-income residents of San Francisco is proceeding apace, the city says. Mayor Gavin Newsom and wireless router company Meraki said this week they're adding wireless coverage to 12 low-income housing projects in the Tenderloin neighborhood, CNET News says. Meraki says about 150,000 of the city's 860,000 residents are on its network, and it will be a few more years before the entire city is covered.

Call it the Google lift or the Microsoft bump. This spring, these tech powerhouses announced they were entering the field of personal health records, and that has energized other players in the field. It also has set many in the health IT community to thinking: Will the presence of these Internet giants provide the oomph needed to turn the corner on converting patients' paper medical records into a digital system that connects hospitals to doctors and other providers of health care?

Tired of the stress of stop-and-go driving? An engineer in San Francisco has a proposed solution, a robot-driven car that makes the decisions for you---speeding up, braking, staying in the lane all on its own. CNET News reports that the engineer, Anthony Levandowski, demonstrated the system he built into a Toyota Prius by having the car navigate its own way through San Francisco last week.

Airplanes Remain No-Call Zones

Airlines have started providing Internet hookups on their flights, but at least one says that passengers won't be allowed to use voice-over-Internet-Protocol (VoIP) to make telephone calls over the connections. The New York Times says that service-provider Aircell and American Airlines block Skype, Vonage, and similar programs, because they worry the conversations will annoy other passengers. No airline so far plans to allow phone calls.

According to New Scientist, engineers have tested a converted craft to carry medical samples of blood, urine, or sputum, or up to two units of blood, for between hard-to-reach clinics in parts of South Africa and distant medical labs. Use of the vehicles - which, at about 1 foot long, resemble toys -  should speed up diagnosis and treatment of diseases such as tuberculosis.
