NASA's planet-hunting Kepler telescope is broken, potentially jeopardizing the search for other worlds where life could exist outside our solar system.
Engineers have transformed bacterial cells into living calculators that can compute logarithms, divide and take square roots, using three or fewer genetic parts.
Pioneering X-ray technology is making it possible to read fragile rolled-up historical documents for the first time in centuries.
Chinese scientists have conducted an experiment in the high-altitude atmosphere and near-Earth space with the launch of a sounding rocket.
Researchers have developed guidelines that are being used by the timber industry and government foresters to get a jump on climate change when planting trees.
Two fossil discoveries from the East African Rift reveal new information about the evolution of primates.
A dramatic new image of cosmic clouds in the constellation of Orion reveals what seems to be a fiery ribbon in the sky.
