Scientists have long argued about where and how such pyrophilous (fire-loving) fungi survive, sometimes for decades, between fires. A new study finds that some of these fungi hide out in the tissues of mosses and lichens.Potato as effective as carbohydrate gels for boosting athletic performance, study findsOct 18, 2019 11:45 am11060 views Consuming potato puree during prolonged exercise works just as well as a commercial carbohydrate gel in sustaining blood glucose levels and boosting performance in trained athletes, scientists report.Prescribing oral opioids for dogs likely doesn’t help them, veterinary experts sayOct 14, 2019 7:45 am3719 views Sending ailing dogs home with oral opioids may not be an effective way to manage their pain, experts report in a free, online continuing education program recently developed for veterinarians. In light of growing evidence that such drugs don’t work well in dogs – added to the fact that humans sometimes abuse opioids prescribed for pets – the common practice of prescribing oral opioids for dogs in pain should be reexamined, the experts say. Anticipating the need among opioid prescribers for additional training to meet regulatory mandates, these experts created an online continuing education program that addresses the problem. The training includes cautions about unwarranted prescription of oral opioids and advice on effective pain management for veterinary patients. Researchers repurpose failed cancer drug into printable semiconductorOct 2, 2019 9:30 am1195 views Many potential pharmaceuticals end up failing during clinical trials, but thanks to new research from the University of Illinois, biological molecules once considered for cancer treatment are now being repurposed as organic semiconductors for use in chemical sensors and transistors.Study finds rising ozone a hidden threat to cornOct 1, 2019 6:00 am1403 views Like atmospheric methane and carbon dioxide, ground-level ozone is on the rise. But ozone, a noxious chemical byproduct of fossil fuel combustion, has received relatively little attention as a potential threat to corn agriculture. A new study begins to address this lapse by exposing a genetically diverse group of corn plants in the field to future ozone levels. The study found that some members of the corn family tree are more susceptible than others to yield losses under high ozone air pollution.Purple martin migration behavior perplexes researchersSep 30, 2019 8:00 am1451 views Purple martins will soon migrate south for their usual wintertime retreat, but this time the birds will be wearing what look like little backpacks, as scientists plan to track their roosting sites along the way. The researchers recently discovered that purple martins are roosting in small forest patches as they migrate from North America to Brazil, an unexpected behavior. The scientists published their findings in the Journal of Field Ornithology. How are Illinois birds faring?Sep 24, 2019 8:00 am2059 views According to a new study reported in the journal Science, bird populations in North America have experienced a troubling decline in the past five decades.
