Fragmenting disk gives birth to binary star 'odd couple'  

Charlottesville VA (SPX) Dec 17, 2018 Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered that two young stars forming from the same swirling protoplanetary disk may be twins - in the sense that they came from the same parent cloud of star-forming material. Beyond that, however, they have shockingly little in common. The main, central star of this system, which is located approximately 11,

Pressure tuned magnetism paves the way for novel electronic devices  

Using very sensitive magnetic probes, an international team of researchers has found surprising evidence that magnetism which emerges at the interfaces between non-magnetic oxide thin layers can be easily tuned by exerting tiny mechanical forces. This discovery provides a new and unexpected handle to control magnetism, thus enabling denser magnetic memory, and opens new and unexpected routes for developing novel oxide-based spintronic devices.

Stop that clot! Quantitative assessment of the blood coagulation cascade  

Thrombosis is a harmful activation of the clotting process, which is associated with the occurrence of blood vessel-related diseases. Pathological enhancement of the clotting cascade causes thrombosis, and activated factor X (FXa) is pivotal to this process. Researchers showed that dielectric blood coagulometry provided an easy to use method to detect changes in FXa activity in the presence of various drugs that inhibit the actions of FXa.

Adventures in phase space: Unified map on plastic and elastic glasses  

A research team has simulated glassy colloidal solids to understand their mechanical and failure properties. Under strain, the hard-sphere glasses deformed elastically (reversibly), partly plastically (irreversibly), or underwent yielding or jamming. The size of the elastic and plastic zones on the phase diagram, and the nature of failure, depended on how deeply the glasses were annealed. A unified framework for amorphous solid rheology will have applications across technology and biology.
