  • Portable Raman analyzer detects hydrogen leaks from a distance
    on April 24, 2025 at 5:20 pm

    Researchers have developed a new portable Raman analyzer that can accurately measure very low concentrations of hydrogen gas in ambient air. The instrument could be useful for detecting hydrogen leaks, which pose serious safety risks due to the gas’s flammability and tendency to accumulate in confined spaces.

  • Quantum sensors tested for next-generation particle physics experiments

    To learn more about the nature of matter, energy, space, and time, physicists smash high-energy particles together in large accelerator machines, creating sprays of millions of particles per second of a variety of masses and speeds. The collisions may also produce entirely new particles not predicted by the standard model, the prevailing theory of fundamental particles and forces in our universe. Plans are underway to create more powerful particle accelerators, whose collisions will unleash even larger subatomic storms. How will researchers sift through the chaos?

  • Scientists develop low-cost liquid lenses

    Filipino scientists have discovered a simple, affordable way to make dynamically adjustable water-based lenses that have a wide variety of potential future applications—from classrooms and research labs to cameras and even wearable gadgets. Their research is published in the journal Results in Optics.

  • Nanophotonic platform boosts efficiency of nonlinear-optical quantum teleportation
    on April 24, 2025 at 12:13 pm

    Researchers have long recognized that quantum communication systems would transmit quantum information more faithfully and be impervious to certain forms of error if nonlinear optical processes were used. However, past efforts at incorporating such processes could not operate with the extremely low light levels required for quantum communication.

  • Video game-inspired algorithm rapidly detects high-energy particle collisions for future fusion reactors
    on April 23, 2025 at 8:59 pm

    An innovative algorithm for detecting collisions of high-speed particles within nuclear fusion reactors has been developed, inspired by technologies used to determine whether bullets hit targets in video games. This advancement enables rapid predictions of collisions, significantly enhancing the stability and design efficiency of future fusion reactors.
