Spin transport measured through molecular films now long enough to develop spintronic devices      (via sciencedaily.com)     Original source 

A research group has succeeded in measuring spin transport in a thin film of specific molecules -- a material well-known in organic light emitting diodes -- at room temperature. They found that this thin molecular film has a spin diffusion length of approximately 62 nm, a length that could have practical applications in developing spintronics technology. In addition, while electricity has been used to control spin transport in the past, the thin molecular film used in this study is photoconductive, allowing spin transport control using visible light.

Computers that power self-driving cars could be a huge driver of global carbon emissions      (via sciencedaily.com)     Original source 

A new model quantifies emissions that will be generated by computers on fully autonomous vehicles. If self-driving cars are widely adopted, their emissions will rival those generated by all the data centers in the world today. Keeping emissions at or below those levels would require hardware efficiency to improve more rapidly than its current pace.

Screen-printing method can make wearable electronics less expensive      (via sciencedaily.com)     Original source 

A new study demonstrates that electrodes can be made using just screen printing, creating a stretchable, durable circuit pattern that can be transferred to fabric and worn directly on human skin. Such wearable electronics can be used for health monitoring in hospitals or at home. Current commercial manufacturing of wearable electronics requires expensive processes involving clean rooms. While some use screen printing for parts of the process, this new method relies wholly on screen printing, which can make manufacturing flexible, wearable electronics much easier and less expensive.

Tracking radiation treatment in real time promises safer, more effective cancer therapy      (via sciencedaily.com) 

Radiation, used to treat half of all cancer patients, can be measured during treatment for the first time with precise 3D imaging. By capturing and amplifying tiny sound waves created when X-rays heat tissues in the body, medical professionals can map the radiation dose within the body, giving them new data to guide treatments in real time. It's a first-of-its-kind view of an interaction doctors have previously been unable to 'see.'

An exotic interplay of electrons      (via sciencedaily.com) 

Water that simply will not freeze, no matter how cold it gets -- a research group has discovered a quantum state that could be described in this way. Experts have managed to cool a special material to near absolute zero temperature. They found that a central property of atoms -- their alignment -- did not 'freeze', as usual, but remained in a 'liquid' state. The new quantum material could serve as a model system to develop novel, highly sensitive quantum sensors.
