New technique allows ultrasound to penetrate bone, metal

Researchers from North Carolina State University have developed a technique that allows ultrasound to penetrate bone or metal, using customized structures that offset the distortion usually caused by these so-called "aberrating ...

What evolved first—a dexterous hand or an agile foot?

Resolving a long-standing mystery in human evolution, new research from the RIKEN Brain Science Institute indicates that early hominids developed finger dexterity and tool use ability before the development of bipedal locomotion.

Quadcopter piloted by a smartphone

The quadcopter, which was developed at TU Vienna, can negotiate its way through a room completely on its own. It does not need any human interference, and in contrast to other models, it is not assisted by any external computer. ...

Models move from brain to rain

(Phys.org)—One of climate scientists' key ambitions is to predict future climate change more accurately. They create incredibly detailed computer models, but even these cannot calculate all the infinite detail of the real ...

Three-photon microscopy improves biological imaging

(Phys.org)—Scientists may be a step closer to cracking one of the world's most compelling mysteries: the impossible complexity of the brain and its billions of neurons. Cornell researchers have demonstrated a new way of ...

Human brains outpace chimp brains in the womb

Humans' superior brain size in comparison to their chimpanzee cousins traces all the way back to the womb. That's according to a study reported in the September 25 issue of Current Biology that is the first to track and compare ...
