Scientists have significantly improved a new type of laser that uses sound waves instead of light. This "phonon laser" has potential uses in deep-sea exploration, medical imaging, and other areas. The researchers were able to greatly boost the power and precision of the sound waves by adding a small electronic nudge. This paves the way for future devices using sound for a wider range of tasks.

Traditional optical anti-counterfeiting (AC) is achieved by static printed images, which makes them susceptible to lower levels of security and easier replication. Here in, we fabricated a multifunctional anti-counterfeiting (AC) device based on fluorescent electrophoretic particles, which can achieve dynamic AC display by switching the electric field and UV light. This work demonstrated that fluorescent electrophoretic display (EPD) has a fast response, dynamically switch image and bright luminescence, providing potential in multifunctional AC applications.

A cutting-edge study shows that integrating 5G technology with the BeiDou Navigation Satellite System (BDS) can significantly boost Real-Time Kinematic (RTK) positioning accuracy in urban environments. By combining 5G measurements with BDS, this approach addresses common challenges like signal blockages and visibility issues in cities. The integration reduces positioning errors and enhances the success rate of ambiguity resolution, crucial for applications in autonomous systems and the Internet of Things (IoT).

New research from the University of Washington found lockdowns during the COVID-19 pandemic resulted in unusually accelerated brain maturation in adolescents. This maturation was more pronounced in girls. When measured in terms of the number of years of accelerated brain development, the mean acceleration was 4.2 years in females and 1.4 years in males.

Spin is an intrinsic property of the electron. When electrons spin in the same direction at a given time, the quantity is called polarization. Understanding polarization helps examine the structure of nuclei of heavy elements. Now, nuclear physicists have measured the polarization of an electron beam more precisely than ever before.
