    Study finds producers, consumers must share burden of global plastic pollution

    A new study by an international team of researchers explores the global patterns of plastic packaging waste. The study finds three countries – the U.S., Brazil, and China – are the top suppliers of waste.

    150,000-year-old human tooth rare evidence of Denisovans

    If confirmed, this discovery would be the first fossil evidence that Denisovans — an extinct hominin species that co-existed with Neanderthals and modern humans — lived in southeast Asia.

  • Physics professor Charles Gammie and his team contributed to research that produced the first direct visual evidence of the Sagittarius A star, the supermassive black hole at the center of the Milky Way galaxy.  Image courtesy Event Horizon Telescope collaboration

    U of I astronomers help capture first image of Milky Way's black hole

    Illinois researchers are part of a large international collaboration that unveiled the first image of the supermassive black hole at the center of the Milky Way.

    Ice-capped volcanoes slower to erupt, study finds

    Undergraduate researcher Lilian Lucas and geology professor Patricia Gregg found that additional pressure from thick overlying glacial ice can make volcanic systems more stable and slower to erupt than volcanoes without ice.

    Gas, blasts, and a mystery of star formation

    Post-starburst galaxies were previously thought to scatter all of their gas and dust in violent bursts of energy. A study co-authored by a U of I astronomer reveals that these galaxies don’t scatter all of their star-forming fuel after all. 

  • Illinois researchers Pamela P. Martinez, Christopher B. Brooke and Rebecca L. Smith led a study of SARS-CoV-2 infection dynamics in adults, testing 60 participants daily for up to 14 days.

    Study tracks COVID-19 infection dynamics in adults

    'We capture the most complete, high-resolution, quantitative picture of how SARS-CoV-2 replicates and sheds in people during natural infection. There are no other data like this,' said U. of I. microbiology professor Christopher B. Brooke
