    Gadget makers have for decades relied on ever-shrinking microchips to make more portable, yet more powerful, devices. But as the components used to make these chips become smaller, with widths measured in dozens rather than hundreds of nanometers, they become increasingly more difficult to assemble.  Since microchips are the engines performing the logic functions that make computers, cell phones and countless other electronic gadgets run, technology makers like IBM have been looking to pack more transistors closer together in smaller spaces. Now comes a potential solution.

    The Environment: birds; strategic conservation; big cats.

    The Environment: birds; strategic conservation; big cats.

    In this episode, Cambridge conservation scientist Andrew Balmford discusses the state of the world's birds; the US Fish and Wildlife Service's Rex Johnson talks about a new, strategic approach to conservation (both men were presenters at the recent conference "Conserving Birds in Human-Dominated Landscapes" at the American Museum of Natural History in New York City); and the Wildlife Conservation Society's Alan Rabinowitz describes his efforts to save the world's big cats. Plus, test your knowledge about some recent science in the news.
