Carbon-carbon covalent bonds far more flexible than presumed

A Hokkaido University research group has successfully demonstrated that carbon-carbon (C-C) covalent bonds expand and contract flexibly in response to light and heat. This unexpected flexibility of C-C bonds could confer ...

Detection of gravitational wave 'lensing' could be some way off

Gravitational wave scientists looking for evidence of "lensing," in which the faintest gravitational wave signals become amplified, are unlikely to make these detections in the near future according to new analysis by scientists ...

Image: Simulated satellite rendezvous

A camera closes in on a detailed model satellite, to simulate the extreme "guidance navigation and control" (GNC) challenge of rendezvousing with an uncooperative target, such as a derelict satellite or distant asteroid.

New type of plastic made from reclaimed waste

A new type of plastic made of reclaimed waste readily degrades in less than a year. The substance that will soon serve to manufacture and break down mainly disposable products in an ecofriendly way goes by the name of polyhydroxybutyrate. ...

Simulator for drilling at depths up to 5,000 meters

To tap into geothermal reservoirs, boreholes must be drilled deeply into the earth's crust. Due to the extreme pressures and temperatures involved, this is expensive and time consuming. A research team from Fraunhofer IEG ...
