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 am12203 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 am4265 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 am1271 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 am1584 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 am2022 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.

Instead of trying to fix these flaws, the team set out to use them to help direct molecules into the membrane pores.Infants expect leaders to right wrongs, study findsJul 29, 2019 2:00 pm1002 views Infants 17 months of age expect leaders – but not others – to intervene when one member of their group transgresses against another, a new study reveals. The findings add to growing evidence that children in their second year of life have a well-developed understanding of social hierarchies and power dynamics, the researchers say. Left eye? Right eye? American robins have preference when looking at decoy eggsJul 23, 2019 7:00 pm1134 views Just as humans are usually left- or right-handed, other species sometimes prefer one appendage, or eye, over the other. A new study reveals that American robins that preferentially use one eye significantly more than the other when looking at their own clutch of eggs are also more likely to detect, and reject, a foreign egg placed in their nest by another bird species – or by a devious scientist.For anemonefish, male-to-female sex change happens first in the brainJul 23, 2019 8:30 am1973 views The anemonefish is a gender-bending marvel. It starts out as a male, but can switch to female when circumstances allow – for example, when the only female present dies or disappears. In a new study, researchers found that the male-to-female sex-change occurs first in the fish’s brain and only later involves the gonads – sometimes after a delay of months or years.Human waste an asset to economy, environment, study findsJul 8, 2019 8:00 am2547 views Human waste might be an unpleasant public health burden, but scientists at the University of Illinois see sanitation as a valuable facet of global ecosystems and an overlooked source of nutrients, organic material and water.Aggressive, non-native wetland plants squelch species richness more than dominant natives doJun 19, 2019 8:30 am713 views Dominant, non-native plants reduce wetland biodiversity and abundance more than native plants do, researchers report in the journal Ecology Letters. Even native plants that dominate wetland landscapes play better with others, the team found.Biochar may boost carbon storage, but benefits to germination and growth appear scantJun 19, 2019 8:15 am1320 views Biochar may not be the miracle soil additive that many farmers and researchers hoped it to be, according to a new University of Illinois study. Biochar may boost the agricultural yield of some soils – especially poor quality ones – but there is no consensus on its effectiveness. Researchers tested different soils’ responses to multiple biochar types and were unable to verify their ability to increase plant growth. However, the study did show biochar’s ability to affect soil greenhouse gas emissions.New insight from Great Barrier Reef coral provides correction factor to global climate recordsJun 18, 2019 9:45 am920 views Newly developed geological techniques help uncover the most accurate and high-resolution climate records to date, according to a new study.
