Fluorescing Lab Worms Signal Longer Life Spans

Facebook X LinkedIn Email
BOULDER, Colo., July 28 -- University of Colorado at Boulder (CU-Boulder) scientists have used a fluorescent marker to predict the individual life spans of identical worms that were genetically engineered to illuminate stress levels, implying living organisms have "hidden physiological states" that dictate their ability to deal with the rigors of life. According to Shane Rea, a CU-Boulder research associate, the genetically identical nematodes were engineered with a green fluorescent "reporter" protein coupled to a stress protein that is present in most multicellular organisms as a monitor of...Read full article

    fluorescent protein
    Fluorescent proteins are proteins that exhibit the property of fluorescence, which is the ability to absorb light at a specific wavelength and emit light at a longer wavelength. These proteins are widely used as molecular tags or markers in molecular and cellular biology to visualize and study the location, movement, and interactions of specific proteins within living cells or organisms. Key features and points about fluorescent proteins include: Fluorescence emission: Fluorescent proteins...
