University of Iowa neuroscientists find in a new study that the brain waves of parents and their child are synced when the parent combines speech with gestures during instruction. The findings could help improve a child’s ability to learn and develop. Results published in the journal Developmental Cognitive Neuroscience.

As electronic devices become increasingly connected, hardware authentication must move beyond stored digital secrets that can be copied or emulated. Researchers developed a graphene-based optical physical unclonable function that uses different combinations of red, green, and blue light as programmable challenges. A transformer-based model converts the resulting diffraction patterns into compact binary response units, demonstrating a route toward spectrally programmable optical authentication for future hardware security in connected devices and edge systems.

In a recent study published in Science China Earth Sciences, researchers from the Research Group of Seismic Anisotropy and Deep Tectoncis, the Institute of Earthquake Forecasting, China Earthquake Administration, present a lithospheric azimuthal anisotropic model in the E margin and SE margin of Tibetan Plateau (model AniCD-L). The model reveals distinct north–south zonation of lithospheric anisotropy and provides evidence that the southwestern boundary of the South China block extends at least to the vicinity of the Red River Fault at the upper mantle scale. The model AniCD-L provides new seismological constraints on intracontinental deformation mechanisms associated with the India–Eurasia collision.
