Physicists create world's smallest engine![]() Dublin, Ireland (SPX) Aug 23, 2019 Theoretical physicists at Trinity College Dublin are among an international collaboration that has built the world's smallest engine - which, as a single calcium ion, is approximately ten billion times smaller than a car engine. Work performed by Professor John Goold's QuSys group in Trinity's School of Physics describes the science behind this tiny motor. The research, published in international journal Physical Review Letters, explains how random fluctuations affect the operation of microscopic ... read more |
DNA origami joins forces with molecular motors to build nanoscale machinesBoston MA (SPX) Jul 22, 2019 Every year, robots get more and more life-like. Solar-powered bees fly on lithe wings, humanoids stick backflips, and teams of soccer bots strategize how to dribble, pass, and score. And, the more r ... more

Pull Me to the Moon: Scientists Revolutionize Space Lift Concept to Save Cash on Lunar Missions New York NY (Sputnik) Sep 02, 2019
There is no need to tether a massive cable to the Earth's surface if you can "dangle" it into Earth's orbit from the Moon, a group of Columbia University scientists say. It would be difficult, but not impossible.
Scientists have come up with an interesting twist on the old concept of space lift, which should, in theory, significantly cut the cost of future Lunar missions, The Daily Star re ... more |
China's KZ-1A rocket launches two satellites Jiuquan, China (XNA) Sep 02, 2019
Two satellites for technological experiments were sent into space by a Kuaizhou-1A, or KZ-1A, carrier rocket from the Jiuquan Satellite Launch Center in northwest China on Saturday.
The rocket blasted off at 7:41 a.m. and sent the two satellites into their planned orbit.
Kuaizhou-1A, meaning speedy vessel, is a low-cost solid-fuel carrier rocket with high reliability and a short prep ... more |

Iraq paramilitary force says Israel behind latest drone attack Baghdad (AFP) Aug 25, 2019
Iraq's Hashed al-Shaabi accused Israel of a deadly drone attack on Sunday that left one paramilitary fighter dead, the first time the force has directly blamed the Jewish state for such a raid.
The attack struck a position held by Brigade 45, a Hashed al-Shaabi unit based near Al-Qaim about 15 kilometres (10 miles) from Iraq's western desertic border with neighbouring Syria.
It is the l ... more |

Towards an 'orrery' for quantum gauge theory Zurich, Switzerland (SPX) Aug 23, 2019
The interaction between fields and matter is a recurring theme throughout physics. Classical cases such as the trajectories of one celestial body moving in the gravitational field of others or the motion of an electron in a magnetic field are extremely well understood, and predictions can be made with astonishing accuracy.
However, when the quantum character of the particles and fields inv ... more |
