UC San Diego has developed CHARM, a prototype ring that tracks up to four biochemical markers from sweat. Individual calibration for glucose estimation and validation on only three people highlight the challenges toward clinical application.
New geological modeling and 3D analysis of China's Bayan Obo deposit suggest rare earths may extend more than twice as deep as previously expected. A new theory proposing two overlapping volcanic events that supersized the deposit has also emerged, with hopes that potential resources could be several times larger than current estimates.
A research team at Nagoya University has established a “skeletal editing” technique that directly rearranges the internal bonds of robust nanographenes. This technology has enabled the introduction of ten-membered rings into giant molecules—previously considered extremely difficult—as well as precise asymmetric synthesis, opening the way for the development of next-generation materials with heat resistance and gas-adsorption capability.
Fusion venture Thea Energy has received $20 million in US government support to begin building a mass-production line for its proprietary planar high-temperature superconducting magnets. This technology compensates for complex geometry through control systems, shifting the manufacturing bottleneck from individual prototypes to uniform mass production, with the aim of accelerating the construction of a demonstration reactor.
A research team led by the University of Michigan has developed a technology that controls the direction of electron motion using only quantum interference of light, without applying any voltage. By interfering two-photon and three-photon absorption pathways, they generated bullet-like currents unaffected by impurity scattering, and succeeded in freely changing the current's direction simply by manipulating the polarization of light.
Photon Queue has deployed its room-temperature quantum memory—a device that temporarily holds photons—at Sandia National Laboratories and the University of Maryland. A $4 million round will expand manufacturing and customer deployment.
A new parallel computing method has been demonstrated in which hundreds of microscopic particles vibrating in a liquid transform data into high-dimensional representations through complex collective motion. Rather than relying on the precise control of electronic circuits, this approach harnesses physical phenomena themselves as a computational resource, achieving roughly a 50-fold speedup in data-processing latency and enabling the detection of subtle anomalies.
