    Coordinating complex behaviors between hundreds of robots

    In one of the more memorable scenes from the 2002 blockbuster film Minority Report, Tom Cruise is forced to hide from a swarm of spider-like robots scouring a towering apartment complex. While most viewers are likely transfixed by the small, agile bloodhound replacements, a computer engineer might marvel instead at their elegant control system. In […] More

    Clinical-grade wearables offer continuous monitoring for COVID-19

    Although it might be tempting to rely on your fitness tracker to catch early signs of COVID-19, Northwestern University researchers caution that consumer wearables are not sophisticated enough to monitor the complicated illness. The Northwestern team, led by bioelectronics pioneer John A. Rogers, published a perspective today (July 1) in the journal Science Advances, in […] More

    Toward principles of gene regulation in multicellular systems?

    A team of quantitative biology researchers from Northwestern University have uncovered new insights into the impact of stochasticity in gene expression, offering new evolutionary clues into organismal design principles in the face of physical constraints. In cells, genes are expressed through transcription, a process where genetic information encoded in DNA is copied into messenger RNA […] More

    Tabletop quantum experiment could detect gravitational waves

    Predicted by Einstein’s general theory of relativity, gravitational waves are ripples in space-time generated by certain movements of massive objects. They are important to study because they allow us to detect events in the universe that would otherwise leave little or no observable light, like black hole collisions. In 2015, the Laser Interferometer Gravitational-Wave Observatory […] More

    Study reveals magnetic process that can lead to more energy-efficient memory in computers

    Researchers at Virginia Commonwealth University and the University of California, Los Angeles have made an important advance that could lead to more energy efficient magnetic memory storage components for computers and other devices. Magnets are widely used for computer memory because their “up” or “down” polarity — the magnetic state — can be “flipped” to […] More

    Ultrafast light wave electronics: Light from inside the tunnel

    Steering and monitoring the light-driven motion of electrons inside matter on the time-scale of a single optical cycle is a key challenge in ultrafast light wave electronics and laser-based material processing. Physicists from the Max Born Institute in Berlin and the University of Rostock have now revealed a so-far overlooked nonlinear optical mechanism that emerges […] More
