Green, saltwater-based battery leans on a new anode to go the distance

The lithium-ion batteries that power much of the modern world may be our best solution currently, but scientists continue to experiment with their makeup in pursuit of devices that are safer and less environmentally costly (among other desirable attrib… Continue reading Green, saltwater-based battery leans on a new anode to go the distance

Next-gen battery leans on copper-tin film to avoid rapid failure

Scientists at the University of Central Florida studying alternative lithium battery designs have come up with a modification to one they say could lead to great performance gains for these devices. The breakthrough centers on a new protective coating … Continue reading Next-gen battery leans on copper-tin film to avoid rapid failure

Arecibo Observatory damaged in accident, operations suspended

Science operations have been suspended at the Arecibo Observatory in Puerto Rico after the radio telescope was damaged on Monday August 10. An auxiliary cable supporting a platform appears to have snapped and fallen, damaging the dish.Continue ReadingC… Continue reading Arecibo Observatory damaged in accident, operations suspended

Spacetime wave packets: New class of laser defies laws of light physics

Scientists have created a new class of laser beam that appears to violate long-held laws of light physics. These new beams, which the team calls “spacetime wave packets,” follow different rules of refraction, which could lead to new communication techn… Continue reading Spacetime wave packets: New class of laser defies laws of light physics

World-first “impossible” rotating detonation engine fires up

A Florida team working with the US Air Force claims that it’s built and tested an experimental model of a rotating detonation rocket engine, which uses spinning explosions inside a ring channel to create super-efficient thrust.Continue ReadingCategory:… Continue reading World-first “impossible” rotating detonation engine fires up
