    Why you need a computer to understand strings and knots


    Some questions are simply too big for humans to answer alone. “How does the universe work?” is a good example. James Halverson and Brent Nelson, physicists at Northeastern, are getting a little extra help from artificial intelligence to uncover the secrets of why we exist.

    ‘A network is crucial to describe how infectious disease spreads, and this is what we do’


    On Thursday, Joseph E. Aoun, president of Northeastern, joined Alessandro Vespignani, who directs the Network Science Institute, to discuss where we are now in the COVID-19 crisis, where we’re headed, and what policymakers can do to prepare for the next pandemic.

    Models can predict how COVID-19 will spread. What goes into them, and how can we use what they tell us?


    On Thursday, Joseph E. Aoun, president of Northeastern, will sit down for a conversation with Alessandro Vespignani, the director of Northeastern’s Network Science Institute, who is leading one of the major efforts to model this disease.

    The coronavirus was in the US in January. We need to understand how we missed it.


    SARS-CoV-2, the coronavirus that causes COVID-19, was circulating in major U.S. cities as early as January, says Alessandro Vespignani, director of Northeastern’s Network Science Institute. And if we want to keep our communities safe going forward, we need to understand how we missed a virus that was right under our noses.

    Network scientists identify 40 new drugs to test against COVID-19


    Researchers at Northeastern mapped the way proteins within human cells behave after a cell is hijacked by the virus to find new and existing drugs that might be able to fight COVID-19. The team is now working with other experimental researchers to begin testing those drugs.

    ‘Social distancing’ is only the first step toward stopping the COVID-19 pandemic


    After days of closures and requests—or orders—to stay home, many people caught in the heart of the COVID-19 pandemic are wondering if these efforts will be enough. Network scientist Alessandro Vespignani says the answer depends on the ways that local, regional, and federal governments use the time.

    Closing borders can delay, but can’t stop the spread of COVID-19, new report says


    Travel restrictions will not stop the spread of COVID-19, but observing quarantines and avoiding public events gives us a chance to slow the epidemic, says Matteo Chinazzi, a research scientist in the Network Science Institute. “Closing airports will buy you time, but it’s not enough.”

    Physicists may have accidentally discovered a new state of matter. The possibilities are endless.


    “Imagination is the limit,” says Swastik Kar, an associate professor of physics. “It could change the way we can detect and communicate signals. It could change the way we can sense things and the storage of information, and possibilities that we may not have even thought of yet.”

    How long can China’s mass quarantine stave off a coronavirus pandemic?


    Though the effort to head off a pandemic is centered in China now, the rest of the world cannot close itself off forever, said speakers at a panel on Northeastern’s Boston campus Wednesday convened to discuss the outbreak.
