A research team at the College of Science, National University of Defense Technology has proposed a compact way to generate and manipulate relativistic mid-infrared light using transversely magnetized plasma. Their studies demonstrated that a magnetized plasma can function as a relativistic waveplate, enabling both frequency conversion and polarization manipulation within a single laser-plasma interaction process. The advance points to a new class of plasma optical components capable of operating in regimes far beyond conventional optical devices.

Human epidermal growth factor receptor 2 (HER2) is a critical protein in cancer cell growth that signifies the aggressiveness of breast cancer (BC) and helps predict its prognosis.  Researchers at UCLA have introduced  a compact and cost-effective lensfree holography device integrated with deep learning for rapid, automated HER2 scoring of immunohistochemically stained breast tissue sections. 

Scientists have discovered that the electroactive bacterium Geobacter sulfurreducens can extract electrons directly from stainless steel to power its metabolism. Surprisingly, this is accomplished without destroying the metal’s protective chromium-oxide passive film, revealing a new mechanism by which microbes can accelerate corrosion of materials widely used in infrastructure and industry.
