Engineers have developed the smallest-ever remote-controlled walking robot -- and it comes in the form of a tiny, adorable peekytoe crab. Just a half-millimeter wide, the tiny crabs can bend, twist, crawl, walk, turn and even jump. Although the research is exploratory at this point, the researchers believe their technology might bring the field closer to realizing micro-sized robots that can perform practical tasks inside tightly confined spaces.

Researchers have now designed a micro-sized artificial cilial system using platinum-based components that can control the movement of fluids at such a scale. The technology could someday enable low-cost, portable diagnostic devices for testing blood samples, manipulating cells or assisting in microfabrication processes.

Researchers have succeeded in teleporting quantum information across a rudimentary network. This first of its kind is an important step towards a future quantum Internet. This breakthrough was made possible by a greatly improved quantum memory and enhanced quality of the quantum links between the three nodes of the network.

Several hundred settlements from the time between 500 and 1400 AD lie in the Bolivian Llanos de Mojos savannah and have fascinated archaeologists for years. Researchers have now visualized the dimensions of the largest known settlement of the so-called Casarabe culture. Mapping with the laser technology LIDAR indicates that it is an early urbanism with a low population density -- the only known case so far from the Amazon lowlands. The results shed new light on how globally widespread and diverse early urban life was and how earlier societies lived in the Amazon.

Our brains lose the ability to link related memories as we age. Scientists genetically restored this brain function in middle-aged mice and identified an FDA-approved drug that achieves the same thing. The study suggests a new approach for combating middle-aged memory loss and a possible early intervention for dementia.

Paleontologists have debated whether dinosaurs were warm-blooded, like modern mammals and birds, or cold-blooded, like modern reptiles. In a new paper, scientists are unveiling a new method for studying dinosaurs' metabolic rates, using clues in their bones.

A team of astrophysicists has arrived at a major result regarding star populations beyond the Milky Way. The result could change our understanding of a wide range of astronomical phenomena, including the formation of black holes, supernovae and why galaxies die.

Researchers have created a solar cell with a record 39.5 percent efficiency under 1-sun global illumination. This is believed to be the highest efficiency solar cell of any type, measured using standard 1-sun conditions.

NASA's Hubble Space Telescope has calibrated more than 40 'milepost markers' of space and time to help scientists precisely measure the expansion rate of the universe -- a quest with a plot twist.

Researchers have used functional magnetic resonance imaging (fMRI) to study the precise spatial distribution of synchronously working brain regions in anesthetized humans, long-tailed macaques, common marmosets and rats. The scientists were able to show that the areas where burst-suppression is evident differ significantly in primates and rodents.
