    An engineer and an ophthalmologist are working together to develop a portable sensor that can quickly and inexpensively determine whether an eye injury is mild or severe. The device, called OcuCheck, works by measuring levels of vitamin C in the fluids that coat or leak from the eye. The sensor could speed efforts to determine the extent of eye injuries at accident sites, in rural areas lacking ophthalmology specialists or on the battlefield, the researchers said.

    Bacteria have many methods of adapting to resist antibiotics, but a new class of spiral polypeptides developed at the University of Illinois targets one thing no bacterium can live without: an outer membrane.

  • Study: Alaskan boreal forest fires release more carbon than the trees can absorb

    A new analysis of fire activity in Alaska's Yukon Flats finds that so many forest fires are occurring there that the area has become a net exporter of carbon to the atmosphere. This is worrisome, the researchers say, because arctic and subarctic boreal forests like those of the Yukon Flats contain roughly one-third of the Earth's terrestrial carbon stores.

    A University of Illinois researcher is designing a robot – actually a computer system – that will communicate with humans through jazz improvisation and provide insight into artificial intelligence and human-computer interaction.

  • Catalyst combining reactivity and selectivity could speed drug development

    Chemists have long believed that inserting nitrogen – a beneficial ingredient for making many pharmaceuticals and other biologically active molecules – into a carbon-hydrogen bond requires a trade-off between catalyst reactivity and selectivity. But a new manganese-based catalyst developed by University of Illinois chemists has given researchers both in one efficient, lower-cost package.

  • COMPASS method points researchers to protein structures

    Searching for the precise, complexly folded three-dimensional structure of a protein can be like hacking through a jungle without a map: a long, intensive process with uncertain direction.

    Two of the 20th century’s greatest minds, one of them physicist Albert Einstein, came to intellectual blows one day in Paris in 1922. One immediate result of the controversy: There would be no mention of relativity in Einstein’s Nobel Prize. One long-term result: a split between science and the humanities. Science historian Jimena Canales tells the tale of that day and the debate that followed in a new book.

  • Mission possible: This device will self-destruct when heated

    Where do electronics go when they die? Most devices are laid to eternal rest in landfills. But what if they just dissolved away, or broke down to their molecular components so that the material could be recycled?
