    The United Nations enacted a new international treaty to halt the erosion of genetic diversity of crops.

  2. Tech

    Nanorods go for the gold

    Gold blobs grown onto the ends of tiny, rod-shaped crystals provide potential points for electric contact and chemical liaisons that could enable such semiconductor bits to self-organize into complex circuits or structures.

  3. Humans

    The high cost of staying current

    Reading peer-reviewed journals remains a primary means by which researchers stay on top of developments in their fields, but the annual costs for these periodicals are steep.

  5. Earth

    Bacteria found to release arsenic into groundwater

    Arsenic gets into groundwater largely through the action of bacteria residing in aquifer sediments.

  6. Physics

    Quantum snare entraps key fifth photon

    By coaxing five quantum particles into a state of entanglement, physicists have taken an important step toward dependable quantum computers and more-versatile schemes for transferring quantum information.

  7. Tech

    Outer space on the cheap

    The first-ever private, manned space mission occurred on June 21.

  8. Female brains know how to fold ’em

    Women compensate for the smaller overall volume of their brains by squeezing more folds into some of the space than men do.

  9. Earth

    Sea Change: Carbon dioxide imperils marine ecosystems
