A compact 300-GHz-band 4×4 bi-directional phased-array transceiver in 65-nm CMOS has been developed, as reported by researchers from Institute of Science Tokyo. While free space path loss is a significant challenge for the 300-GHz-band in wireless systems, this development can mitigate the problem, resulting in significant advancement in 6G wireless communication. 

Traumatic brain injury disrupts complex glial cell networks that influence inflammation, white matter repair, and long-term neurological recovery. A new review highlights how microglia, astrocytes, and oligodendrocytes interact dynamically after injury and explains why future therapies may require carefully timed, multi-target strategies instead of single-drug approaches. The study also outlines emerging treatments that promote remyelination, reduce harmful inflammation, and support regenerative repair processes across different stages of traumatic brain injury progression.

Urban redevelopment in densely populated areas often involves removing existing piles, backfilling boreholes, and installing new piles. Strength differences between backfilled soil and original ground can lead to drilling deviations, compromising building integrity and leading to economic losses. However, current countermeasures are based on experience-based judgements. In a new study, researchers present a new quantitative framework for evaluating drilling instability induced by backfilling, offering practical guidelines for improving resource efficiency, resilience, and sustainability.

RNA design is central to next-generation therapeutics, yet identifying sequences that reliably fold into desired structures remains a major computational challenge, often constrained by high cost and time. A new study from Keio University explores the use of factorization machine with quadratic-optimization annealing (FMQA) for RNA inverse folding, while also examining how different encoding strategies may influence artificial intelligence (AI)-driven design performance, revealing an underexplored dimension of biomolecular engineering.

Chinese scientists have identified five major fundamental scientific questions for extreme complex geological disaster chains: “disaster gestation through multi-sphere interactions, disaster regulation by multi-interface control, disaster propulsion by multi-dynamic coupling, disaster initiation by extreme events, and disaster amplification through multi-disaster chain interactions.” They further reveal the core characteristics of disaster chains from the three dimensions of time, space, and human activities, and construct a coherent “mechanism–prediction–prevention and control” research framework.

A new study published in the Proceedings of the National Academy of Sciences (PNAS) finds that individual human neurons are capable of significantly more complex computations than those of other mammals, offering a fresh view to what makes the human brain unique.
