Scientists have devised an intricate network of carbon dioxide sensors in the Bay Area that could offer objective measurements to evaluate which climate change initiatives are effective in reducing greenhouse gases in the atmosphere. The sensors provide real-time local data on how much carbon dioxide is being emitted, said lead researcher Ronald Cohen, a professor of chemistry and of earth and planetary sciences at the University of California, Berkeley.
A team of local biotech researchers may have found a way to avoid using essential food crops for fuel by genetically modifying harmless strains of a bacteria most people associate with human food poisoning. The result is an extremely expensive fuel — hardly competitive with fossil fuels at $25 per gallon — but marks the beginning of a new look at green energy.
