There and back again: Extending optical storage lifetime by retrieving photon echoes from semiconductor spin excitations

There and back again: Extending optical storage lifetime by retrieving photon echoes from semiconductor spin excitations | Science technology and reaserch | Scoop.it
(Phys.org) —For all of their differences, classical and quantum communication have at least one thing in common: the importance of being able to store optical information. That being said, optical storage is a complex process that depends largely on the material being used to convert, store and retrieve ...

New superconductor world record set

New superconductor world record set | Science technology and reaserch | Scoop.it
A new record for a trapped field in a superconductor, beating a record that has stood for more than a decade, could herald the arrival of materials in a broad range of fields. Researchers managed to 'trap' a magnetic field with a strength of 17.6 Tesla -- roughly 100 times stronger than the field generated by a typical fridge magnet -- in a high temperature gadolinium barium copper oxide (GdBaCuO) superconductor, beating the previous record by 0.4 Tesla.

Let there be light: Chemists develop magnetically responsive liquid crystals for writing tablets, billboards and more | Science technology and reaserch | Scoop.it
Chemists have constructed liquid crystals with optical properties that can be instantly and reversibly controlled by an external magnetic field. The research opens the door to display applications relying on the instantaneous and contactless nature of magnetic manipulation -- such as signage, posters, writing tablets, and billboards. Requiring no electrodes, the liquid crystals have applications in anti-counterfeit technology and optical communication devices for controlling the amplitude, phase, polarization, propagation direction of light.

Sperm-inspired robots controlled by magnetic fields may be useful for drug delivery, IVF, cell sorting and other applications

Sperm-inspired robots controlled by magnetic fields may be useful for drug delivery, IVF, cell sorting and other applications | Science technology and reaserch | Scoop.it
A team of researchers has developed sperm-inspired microrobots, which consist of a head coated in a thick cobalt-nickel layer and an uncoated tail. When the robot is subjected to an oscillating field of less than five millitesla, it experiences a magnetic torque on its head, which causes its flagellum to oscillate and propel it forward. The researchers are then able to steer the robot by directing the magnetic field lines towards a reference point.

Precise, programmable biological circuits | Science technology and reaserch | Scoop.it
Several new components for biological circuits have been developed by researchers. These components are key building blocks for constructing precisely functioning and programmable bio-computers. "The ability to combine biological components at will in a modular, plug-and-play fashion means that we now approach the stage when the concept of programming as we know it from software engineering can be applied to biological computers. Bio-engineers will literally be able to program in future."

Climate change and the ecology of fear

Climate change and the ecology of fear | Science technology and reaserch | Scoop.it
Climate change is predicted to have major impacts on the many species that call our rocky shorelines home. Indeed, species living in these intertidal habitats, which spend half their day exposed to air and the other half submerged by water, may be subjected to a double whammy as both air and water temperatures rise. Given the reliance of human society on nearshore coastal ecosystems, it is critical that we better understand how climate change will affect them.
