第1篇.Earth's Inner Core Speedier Than Outer Shell

Earth's inner core is a solid iron ball slightly smaller than the moon. Little is known about it, but geophysicists confirmed this year that it spins--faster than the solid layers of earth surrounding it.

Geophysicist Xiaodong Song of the University of Illinois at Urbana-Champaign and his colleagues studied seismic waves from doublets--pairs of earthquakes from the same place but occurring at different times. If the inner core was spinning faster, scientists reasoned, seismic waves from doublets would move through the core at different speeds as a result of the inconsistent makeup of the core's iron crystals.

Song calculates that the solid inner core spins just slightly faster per year than the rest of the planet, a difference that adds up to an extra revolution every 1000 years or so. His discovery could help explain how the inner core interacts with convection in the outer core to drive Earth's magnetic field. The field shields us from bombardment by charged particles from the sun.

"We have only a 30-to 40-year snapshot," cautions Song. The data his team uses first became available in the 1960s, when a worldwide seismographic network was established. What happened before that is unknown. Song expects more breakthroughs in the coming years--as long as Earth keeps quaking.

第2篇.Humanoid Robots Walk Tall

In 2005 a new generation of robots revolutionized the way humanoids walk, one of the greatest challenges in engineering. They followed Honda's ASIMO, which wowed a cheering audience last winter by breaking into a two-mile-per-hour trot. ASIMO is based on technology that is much like that of ashuffling windup toy. Every maneuver is part of a programmed pattern, each posture a frozen moment in time, and an enormous amout of energy is needed to keep the body plugging along in a stiff-looking gait. By contrast, a nameless robot unveiled by engineers at cornell University in February is modeled after antique toy figurines that make their way down a slope, depending only on gravity. The Cornell robot is the first to use principles of passivedynamic walking to stroll on level ground, employing electrical energy equivalent to the metablic energy a human would use. Most of the joints swing freely, naturally shifting mass like a pendulum. Another robot, named Rabbit, designed at the University of Michigan and the University of Nantes in France, may be the first to run in strides that look human. Its creators have made it dynamic, balancing on two points--it has no feet--and with the ability to adjust to obstacles and changes in terrain. Unlike ASIMO, which cannot balance in a fluid way, Rabbit can be shoved violently and regain its stability.
