Many current crop models focus on simulating crop growth and yield at the field scale, but lack genetic and physiological data, which may hamper accurate production and environmental impact assessment at larger scales.Cahokia's rise parallels onset of corn agricultureMay 14, 2020 8:15 am5216 views Corn cultivation spread from Mesoamerica to what is now the American Southwest by about 4000 B.C., but how and when the crop made it to other parts of North America is still a subject of debate. In a new study, scientists report that corn was not grown in the ancient metropolis of Cahokia until sometime between A.D. 900 and 1000, a relatively late date that corresponds to the start of the city’s rapid expansion.Molecule reduces multiple pathologies associated with Alzheimer’s diseaseMay 7, 2020 8:15 am1082 views When tested in brain cells and in a mouse model of Alzheimer’s disease, a new compound significantly reduced the number of amyloid plaques in the brain, lessened brain inflammation and diminished other molecular markers of the disease.Nanostimulators boost stem cells for muscle repairMay 1, 2020 8:00 am1211 views In regenerative medicine, an ideal treatment for patients whose muscles are damaged from lack of oxygen would be to invigorate them with an injection of their own stem cells. In a new study published in the journal ACS Nano, researchers at the University of Illinois at Urbana-Champaign demonstrated that “nanostimulators” – nanoparticles seeded with a molecule the body naturally produces to prompt stem cells to heal wounds – can amp up stem cells’ regenerative powers in a targeted limb in mice.Could Legionnaires' bacteria lurk in idled buildings?Apr 29, 2020 2:00 pm1105 views Many businesses are closed as a result of the coronavirus pandemic, and some building managers have shut off water and air conditioning to conserve resources. Unfortunately, warmth and lack of clean water flow can contribute to the growth of potentially dangerous microbes, including the bacteria that contribute to Legionnaires’ disease. Illinois Sustainable Technology Center chemist and industrial water treatment specialist Jeremy Overmann spoke with News Bureau life sciences editor Diana Yates about the problem and potential solutions.Spinal cord gives bio-bots walking rhythmApr 28, 2020 10:00 am739 views Miniature biological robots are making greater strides than ever, thanks to the spinal cord directing their steps.Virus-infected honey bees more likely to gain entrance to healthy hivesApr 27, 2020 2:00 pm3254 views Honey bees that guard hive entrances are twice as likely to allow in trespassers from other hives if the intruders are infected with the Israeli acute paralysis virus, a deadly pathogen of bees, researchers report. Their new study, reported in the Proceedings of the National Academy of Sciences, strongly suggests that IAPV infection alters honey bees’ behavior and physiology in ways that boost the virus’s ability to spread, the researchers say.Holistic approach best for tackling nonmedical drug use, study findsApr 24, 2020 8:15 am1314 views Health practitioners are constantly developing new ways to help those with drug and alcohol addictions wean themselves from their substance of choice. Most such programs have limited success, however. A new study finds that interventions that take a multidimensional approach – tackling the biological, social, environmental and mental health obstacles to overcome while also addressing a person’s substance use – work best for those hoping to stop using drugs.Are bats to blame for the coronavirus crisis?Apr 24, 2020 8:15 am2884 views Horseshoe bats in China are a natural wildlife reservoir of SARS-like coronaviruses. Some health experts think wildlife markets – specifically in Wuhan, China – led to the spillover of the new coronavirus into human populations. Though not confirmed, the hypothesis has given bats around the world a bad rap, and public fears of exposure to bats are on the rise. Illinois Natural History Survey wildlife biologist Tara Hohoff, the project coordinator of the Illinois Bat Conservation Program, spoke to News Bureau life sciences editor Diana Yates about bat biology and conservation, and the flying mammals’ role in human health.Inexpensive, portable detector identifies pathogens in minutesApr 23, 2020 12:00 pm3975 views Most viral test kits rely on labor- and time-intensive laboratory preparation and analysis techniques; for example, tests for the novel coronavirus can take days to detect the virus from nasal swabs. Now, researchers have demonstrated an inexpensive yet sensitive smartphone-based testing device for viral and bacterial pathogens that takes about 30 minutes to complete. The roughly $50 smartphone accessory could reduce the pressure on testing laboratories during a pandemic such as COVID-19.What's new with the plague? More than you might thinkApr 23, 2020 10:00 am2001 views Pandemics of the past are getting new attention, among them the plague of the 14th century. Known as the Black Death, it was medieval, European, bubonic and spread by rats – at least that’s what most of us think. Much of that needs adjustment, however, in large part due to discoveries of the past decade, says Carol Symes, a professor of medieval history at Illinois.Loss of senses of smell, taste could identify COVID-19 carriersApr 14, 2020 2:45 pm3825 views M. Yanina Pepino of the U. of I. is on a global team of experts investigating the abrupt loss of the senses of smell and taste with COVID-19 infection. Study reveals unique physical, chemical properties of cicada wingsApr 14, 2020 8:15 am1153 views Biological structures sometimes have unique features that engineers would like to copy. For example, many types of insect wings shed water, kill microbes, reflect light in unusual ways and are self-cleaning. While researchers have dissected the physical characteristics that likely contribute to such traits, a new study reveals that the chemical compounds that coat cicada wings also contribute to their ability to repel water and kill microbes.New study shows how oxygen transfer is altered in diseased lung tissueApr 9, 2020 12:00 pm2119 views A multidisciplinary team of researchers at the University of Illinois at Urbana-Champaign has developed tiny sensors that measure oxygen transport in bovine lung tissue.
