Ant School: The First Formal Classroom Found in Nature - Live Science   Ants teach other ants how to find food using a poking and prodding technique called "tandem running," a new study reveals. The process is slow. The follower pauses every once and a while—creating a gap between it and the leader—to search for landmarks. When she''s ready to continue, the follower catches up and taps the leader on the hind legs. The experiment reveals the first non-human example of formal instruction. 
Astronomers Weigh "Recycled" Millisecond Pulsar - SpaceDaily   Left:  Shapiro delay in the pulsar PSRJ 1909-3744's signal due to the gravitational field of its companion. (See larger image) In the top panel, diagrams show the configuration of the pulsar and its white dwarf companion in their orbits relative to the line of sight to the observer on the Earth at two key points in the orbit: when the pulsar is closest to the Earth (left, the point of minimum Shapiro delay) and when the pulsar is on the far side of its companion as viewed from Earth (right, the point of maximum Shapiro delay).  This result is of special interest because it gives new insight into the production of millisecond pulsars and may shed light on the laws that govern nuclear matter. 

ESA And ANU Make Space Propulsion Breakthrough - SpaceDaily  The new engine is over ten times more fuel efficient than the one used on SMART-1. "Using a similar amount of propellant as SMART-1, with the right power supply, a future spacecraft using our new engine design wouldn't just reach the Moon, it would be able to leave the Solar System entirely," says Dr Roger Walker of ESA's Advanced Concepts Team, Research Fellow in Advanced Propulsion and Technical Manager of the project. The test model achieved voltage differences as high as 30kV and produced an ion exhaust plume that travelled at 210,000 m/s
