Do AI-driven chemistry labs actually work? New metrics promise answers      (via sciencedaily.com)     Original source 

The fields of chemistry and materials science are seeing a surge of interest in 'self-driving labs,' which make use of artificial intelligence and automated systems to expedite research and discovery. Researchers are now proposing a suite of definitions and performance metrics that will allow researchers, non-experts, and future users to better understand both what these new technologies are doing and how each technology is performing in comparison to other self-driving labs.

Fundamental equation for superconducting quantum bits revised      (via sciencedaily.com)     Original source 

Physicists have uncovered that Josephson tunnel junctions -- the fundamental building blocks of superconducting quantum computers -- are more complex than previously thought. Just like overtones in a musical instrument, harmonics are superimposed on the fundamental mode. As a consequence, corrections may lead to quantum bits that are 2 to 7 times more stable. The researchers support their findings with experimental evidence from multiple laboratories across the globe.

Nanoparticles that can light up the lymph node cancer cells otherwise undetectable by MRI      (via sciencedaily.com)     Original source 

Researchers have developed a new nanoparticle that can 'hitch a ride' on immune cells, or monocytes. Because of its tiny size, the particle can tag along directly into lymph nodes and help metastasis show up on MRIs where it would otherwise be too hard to detect. The process offers game-changing benefits for the early detection of cancer metastasis in the lymph nodes. While previously, metastasis could only be assessed by an increase in lymph node size; the new particles could lead to MRI contrast agents that can highlight metastatic cells in lymph nodes that may otherwise appear normal.

Exploring the effect of ring closing on fluorescence of supramolecular polymers      (via sciencedaily.com)     Original source 

The properties of supramolecular polymers are dictated by the self-assembled state of the molecules. However, not much is known about the impact of morphologies on the properties of nano- and mesoscopic-scale polymeric assemblies. Recently, a research team demonstrated how terminus-free toroids and random coils derived from the same luminescent molecule show different photophysical properties. The team also presented a novel method for purifying the toroidal structure.

Scientists study the behaviors of chiral skyrmions in chiral flower-like obstacles      (via sciencedaily.com)     Original source 

Chiral skyrmions are a special type of spin textures in magnetic materials with asymmetric exchange interactions. They can be treated as quasi-particles and carry integer topological charges. Scientists have recently studied the random walk-behaviors of chiral skyrmions by simulating their dynamics within a ferromagnetic layer surrounded by chiral flower-like obstacles. The simulations reveal that the system behaves like a topological sorting device, indicating its use in information processing and computing devices.
