👀 Lara Croft joins the Delta Force TAKEOVER, the Tomb Raider crossover drops with Season Echo on April 21.
The X trailer places her in Delta Force's gritty setting: she'll fit into hardcore evac runs, large-scale PvP and a campaign in the vein of the "Fall of Black Hawk". Also incoming, new operator Morse, a visual/structural revamp of Zero Dam, plus optimization and technical fixes across PC, consoles and mobile for a proper cross‑pla...
Sensing biological forces with microscopic lasers is an emerging technique that offers significant advantages over conventional fluorescent probes and imaging-based techniques. However, the limited availability of suitable deformable or elastic microlaser materials is restricting the scale of forces that can be detected which strongly narrows their overall applicability. Here, we describe the synthesis of spherical whispering gallery mode microbead lasers from a commercially available elastomer material in a microfluidic system with high viscosity. Upon doping with an organic dye, the microbeads show multimode lasing with thresholds in the range of 2-11 nJ. Measurements of the mechanical properties reveal that the width of the laser modes is directly proportional to the applied external force. The measured mean Young's modulus is 36 kPa, comparable to the stiffness of single cells and soft tissues. We also demonstrate that elastomer microlasers are stable under cell culture conditions for several days and observe splitting of the laser modes for intracellular microlasers. The observed properties render elastomer microlasers as a robust material platform for biointegrated lasers that also allows further tuning of the mechanical and optical properties for tailored force sensing inside cells, tissues, and small animals.

Two Libyan officials say that Ukrainian forces are operating in western Libya and that they used the region to strike a Russian tanker in the Mediterranean last month. The Arctic Metagaz, carrying liquefied natural gas, was damaged in a suspected sea drone attack near Maltese waters in early March. All 30 crew members were rescued. The tanker is part of Russia’s shadow fleet, violating international sanctions. Ukrainian forces, mainly drone experts, are based in Misrata and other locations. The officials claim this is part of a covert deal between Kyiv and Libya’s government, backed by Western countries.
