CLEVELAND, OHIO--In an underdog city, at an underdog NASA lab, researchers are thinking hard about an undeservedly neglected planet. Venus is Earth’s cousin, closest in composition and size, but for decades it has remained veiled. NASA hasn’t sent a mission there since 1989; more recent European and Japanese orbiters have made halting progress that stops largely at the planet’s thick sulfur clouds. No craft has touched down since 1985, when the last of a series of advanced Soviet landers clad in armored pressure vessels endured a couple hours before succumbing to the deep-ocean pressure and furnacelike temperature of the planet’s surface. The baleful conditions and lack of funding have made Venus, Earth’s closest neighbor, feel more distant than ever. That is, except here.

Like the surface of an alien planet, thin sheets of copper display a complex topography of ridges and valleys. These never-before-seen undulations may spell trouble for electronic gadgets: The zigzagging surface could contribute to the electrical resistance of miniature copper wires that snake throughout computer chips.
Using a scanning tunneling microscope, scientists observed nanoscale peaks and dips on a sheet of copper, with angles of a few degrees, researchers report in the July 28 Science. “When we saw that, we were absolutely shocked,” says materials scientist John Boland of Trinity College Dublin. Conventional wisdom was that the copper would lay mostly flat.
Copper and other metals are a conglomeration of smaller bits, known as grains. Within each grain, the atoms are neatly arranged, but at grain boundaries, the pattern is disrupted. In the type of copper the researchers studied, nanocrystalline copper, the grains are particularly small; each has around 1 million atoms. Boland and colleagues showed for the first time that, in films of nanocrystalline copper just tens of nanometers thick, peaks and dips appear where misaligned grains meet.

A long-lasting lake on ancient Mars provided stable environmental conditions that differed significantly from one part of the lake to another, according to a comprehensive look at findings from the first three-and-a-half years of NASA's Curiosity rover mission.

After two months in a coma, Chris Cahill woke up confused about where he was and what had happened to him. Cahill was found unconscious from unknown trauma resulting in severe injuries to his frontal lobe, with brain swelling so dramatic it was life-threatening. Physicians performed emergent surgery to relieve the brain swelling with the intent of replacing the skull after the swelling subsided. However, the patient’s own skull was infected and as a result was unusable. At that point, the doctors decided the best solution to replace the missing skull bone was to use 3-D printing to create a custom cranial skull implant.

3-D scanning using a dip scanner: The object is dipped in a bath of water (left) by a robot arm. The quality of the reconstruction improves as the number of dipping orientations is increased (from left to right).
'Using a robotic arm to immerse an object on an axis at various angles, and measuring the volume displacement of each dip, we combine each sequence and create a volumetric shape representation of an object,' says an expert.
