Davis, California - Rock soil droplets formed by heating most likely came from Stone Age house fires and not from a disastrous cosmic impact 12,900 years ago, according to new research from the University of California, Davis. The study, of soil from Syria, is the latest to discredit the controversial theory that a cosmic impact triggered the Younger Dryas cold period.

Davis, California - After it was first domesticated from the wild teosinte grass in southern Mexico, maize, or corn, took both a high road and a coastal low road as it moved into what is now the U.S. Southwest, reports an international research team that includes a UC Davis plant scientist and maize expert.

Stanford, California - In a new paper in Science a research team led by Stanford postdoctoral scholar Ling Cao and Professor Rosamond Naylor offers the clearest picture to date of China's enormous impact on wild fisheries. The study also presents a more sustainable alternative to the current practice of using wild-caught fish to feed farm-raised fish.

Cambridge, Massachusetts - MIT senior Katie Bodner thrives in fields that are full of unanswered questions: She arrived at the Institute with little research experience, and from a family with no scientists, but now a biological engineering major, she has found her place working on projects in synthetic biology, biological-based pharmaceuticals, and programmable vaccines.

Cambridge, Massachusetts - A team of researchers has built an array of light detectors sensitive enough to register the arrival of individual light particles, or photons, and mounted them on a silicon optical chip. Such arrays are crucial components of devices that use photons to perform quantum computations.

Cambridge, Massachusetts - In 2007, Google unleashed a fleet of cars with roof-mounted cameras to provide street-level images of roads around the world. Now MIT spinout Essess is bringing similar “drive-by” innovations to energy efficiency in homes and businesses.
