These signals are packaged in membrane-bound compartments called extracellular vesicles.Beneficial arthropods find winter sanctuary in uncultivated field edges, study findsJun 3, 2021 8:00 am637 views Many species of ground-dwelling beetles, ladybugs, hoverflies, damsel bugs, spiders and parasitic wasps kill and eat pest species that routinely plague farmers, including aphids and corn rootworm larvae and adults. But the beneficial arthropods that live in or near cropped lands also are susceptible to insecticides and other farming practices that erase biodiversity on the landscape. A new study reveals that beneficial arthropods are nearly twice as abundant and diverse in uncultivated field edges in the spring as they are in areas that are cropped – if those field edges are rich in an array of flowers and other broad-leaved plants and not just mowed grass.Geology helps map kidney stone formation from tiny to troublesomeMay 25, 2021 1:00 pm1211 views Advanced microscope technology and cutting-edge geological science are giving new perspectives to an old medical mystery: How do kidney stones form, why are some people more susceptible to them and can they be prevented?Study: Fluorescent light clarifies relationship between heat stress and crop yieldMay 24, 2021 9:15 am821 views Scientists report that it is possible to detect and predict heat damage in crops by measuring the fluorescent light signature of plant leaves experiencing heat stress. If collected via satellite, this fluorescent signal could support widespread monitoring of growth and crop yield under the heat stress of climate change, the researchers say.Portable, affordable, accurate, fast: Team invents new COVID-19 testMay 18, 2021 4:00 am1562 views A new coronavirus test can get accurate results from a saliva sample in less than 30 minutes, researchers report in the journal Nature Communications.

Team cracks eggs for scienceApr 8, 2021 8:00 am321 views Avian brood parasites lay their eggs in the nests of other bird species, forcing the hosts to do the hard work of raising the unrelated young. A team of scientists wanted to simulate the task of piercing an egg – a tactic that only a minority of host birds use to help grasp and eject the foreign eggs. Published in the Journal of Experimental Biology, the study offers insight into some of the physical challenges the discriminating host birds face.Study links prenatal phthalate exposure to altered information processing in infantsApr 6, 2021 7:30 am18581 views Researchers have found evidence linking pregnant women’s exposure to phthalates to altered cognitive outcomes in their infants.More protein doesn't mean more strength in resistance-trained middle-aged adultsMar 25, 2021 7:30 am3075 views A 10-week muscle-building and dietary program involving 50 middle-aged adults found no evidence that eating a high-protein diet increased strength or muscle mass more than consuming a moderate amount of protein while training. The intervention involved a standard strength-training protocol with sessions three times per week. None of the participants had previous weightlifting experience.Microscope that detects individual viruses could power rapid diagnosticsMar 19, 2021 11:30 am1205 views A fast, low-cost technique to see and count viruses or proteins from a sample in real time, without any chemicals or dyes, could underpin a new class of devices for rapid diagnostics and viral load monitoring, including HIV and the virus that causes COVID-19.Study: Black bears are eating pumas' lunchMar 19, 2021 8:00 am1480 views A camera-trap study in the Mendocino National Forest in Northern California reveals that black bears are adept at finding and stealing the remains of adult deer killed by pumas. This “kleptoparasitism” by bears, as scientists call it, reduces the calories pumas consume in seasons when the bears are most active. Perhaps in response to this shortage, the pumas hunt more often and eat more small game when the bears are not in hibernation.Not just CO2: Rising temperatures also alter photosynthesis in a changing climateMar 16, 2021 8:00 am2335 views A new review explores how increasing temperatures influence plant growth and viability despite the higher concentrations of atmospheric CO2.'Hunker down' stress genes boosted in women who live in violent neighborhoodsMar 11, 2021 9:00 am1055 views The chronic stress of living in neighborhoods with high rates of violence and poverty alters gene activity in immune cells, according to a new study of low-income single Black mothers on the South Side of Chicago. The changes in stress-related gene expression reflect the body’s “hunker down” response to long-term threat. This has implications for health outcomes in communities of color and other marginalized populations, said researchers at the University of Illinois Urbana-Champaign and collaborators.Study compares discrimination claims of younger and older Americans with cancerMar 10, 2021 8:00 am506 views Researchers assessed the employment discrimination claims made by younger and older American adults with cancer and found substantial differences in the nature – and outcomes – of their claims.Veterans see positive changes in emotional resilience after interventionMar 8, 2021 11:00 pm443 views A six-week training program designed to strengthen resilience against emotional distress in military veterans was associated with positive changes in brain function and increased confidence in their ability to regulate emotions, researchers report.Division of labor within regenerating liver maintains metabolism, mouse study findsMar 1, 2021 2:00 pm641 views The liver has a rare superpower among body organs – the ability to regenerate, even if 70% of its mass is removed. It also keeps up its metabolic and toxin-removing work during the process of regeneration, thanks to a subset of cells that expand their workload while the rest focus on multiplication, a new study in mice found.Online edition of Insect Fear Film Festival to feature pandemic vectors: fleasFeb 19, 2021 11:45 am771 views The Insect Fear Film Festival Featuring Fleas will look at the insects as entertainment in the form of flea circuses, as pests and as vectors of disease.Study: Preschoolers with higher cardiorespiratory fitness do better on cognitive testsFeb 18, 2021 8:15 am1565 views Researchers report that 4-6-year-old children who walk further than their peers during a timed test – a method used to estimate cardiorespiratory health – also do better on cognitive tests and other measures of brain function. Published in the Journal of Clinical Medicine, the study suggests that the link between cardiorespiratory fitness and cognitive health is evident even earlier in life than previously appreciated.3D microscopy clarifies understanding of body's immune response to obesityFeb 17, 2021 1:00 pm1091 views Researchers who focus on fat know that some adipose tissue is more prone to inflammation-related comorbidities than others, but the reasons why are not well understood. Thanks to a new analytical technique, scientists are getting a clearer view of the microenvironments found within adipose tissue associated with obesity. This advance may illuminate why some adipose tissues are more prone to inflammation – leading to diseases like type 2 diabetes, cancer and cardiovascular disorders – and help direct future drug therapies to treat obesity.Study links prolonged sedentary time to distractibility in adults with obesity or overweightFeb 17, 2021 8:15 am555 views Scientists used accelerometers to track daily activity levels for a week in 89 adults with obesity or overweight and, in a series of tests, measured their ability to multitask and maintain their attention despite distractions. The study revealed that individuals who spent more sedentary time in bouts lasting 20 minutes or more were less able to overcome distractions.Are science laboratories truly inclusive if not accessible to service-dog handlers?Feb 16, 2021 8:15 am2159 views According to a new commentary in Disability and Health Journal, people with disabilities who rely on service dogs often are prohibited from bringing their working dogs into teaching and research laboratories. This one barrier can stop them from pursuing careers in science, says Joey Ramp, a researcher in the Beckman Institute for Advanced Science and Technology and lead author of the commentary. Ramp spoke about the issue with News Bureau life sciences editor Diana Yates.Lipid epoxides target pain, inflammatory pathways in neuronsFeb 10, 2021 4:00 am1695 views A process known as epoxidation converts two naturally occurring lipids into potent agents that target multiple cannabinoid receptors in neurons, interrupting pathways that promote pain and inflammation, researchers report in a new study.

Mice that had experienced stress when young were more likely to develop the autoimmune disorder and less likely to respond to a common treatment, researchers at the University of Illinois Urbana-Champaign found. However, treatment that activated an immune-cell receptor mitigated the effects of childhood stress in the mice.Culture shapes willingness to share personal data to reduce COVID-19 spreadJan 27, 2021 8:00 am1009 views Culture, civic-mindedness and privacy concerns influence how willing people are to share personal location information to help stem the transmission of COVID-19 in their communities, a new study finds. Such sharing includes giving public health authorities access to their geographic information via data gathered from phone calls, mobile apps, credit card purchases, wristband trackers or other technologies.Genome-editing tool TALEN outperforms CRISPR-Cas9 in tightly packed DNAJan 27, 2021 4:00 am1790 views Researchers used single-molecule imaging to compare the genome-editing tools CRISPR-Cas9 and TALEN. Their experiments revealed that TALEN is up to five times more efficient than CRISPR-Cas9 in parts of the genome, called heterochromatin, that are densely packed. Fragile X syndrome, sickle cell anemia, beta-thalassemia and other diseases are the result of genetic defects in the heterochromatin.Medicaid expansion helps uncover undiagnosed HIV infectionsJan 26, 2021 8:00 am673 views The Medicaid expansion facilitated by the Affordable Care Act led to a 13.9% increase in the identification of undiagnosed HIV infections, says research co-written by a team of University of Illinois Urbana-Champaign experts who study health care and public policy.Online smell, taste challenge offered as early detection tool for COVID-19Jan 25, 2021 3:00 pm2448 views The smell and taste challenge, developed by the Global Consortium for Chemosensory Research, is a web-based tool people can use to easily monitor changes in these senses using their favorite morning beverage.COVID-19 cases, deaths in U.S. increase with higher income inequalityJan 25, 2021 9:45 am1187 views U.S. counties with higher income inequality faced higher rates of COVID-19 cases and deaths in the earlier months of the pandemic, according to a new study led by University of Illinois Urbana-Champaign sociology professor Tim Liao. Counties with higher proportions of Black or Hispanic residents also had higher rates, the study found, reinforcing earlier research showing the disparate effects of the virus on those communities.Study: Negative mental health effects of pandemic lockdowns spike, then fadeJan 25, 2021 8:00 am1558 views Social distancing policies correlated with immediate increases in interest in information about “isolation” and “worry” – but those effects tapered off two to four weeks after their respective peaks, says new research co-written by Dolores Albarracín, a professor of psychology and of business administration at Illinois, and Bita Fayaz Farkhad, an economist and a postdoctoral researcher in psychology at Illinois.Gut bacteria help digest dietary fiber, release important antioxidantJan 19, 2021 11:00 am1133 views Dietary fiber found in grains is a large component of many diets, but little is understood about how we digest the fiber, as humans lack enzymes to break down the complex molecules. Some species of gut bacteria break down the fiber in such a way that it not only becomes digestible, but releases ferulic acid, an important antioxidant with multiple health benefits, according to a new study led by researchers at the University of Illinois Urbana-Champaign.50 million-year-old fossil assassin bug has unusually well-preserved genitaliaJan 19, 2021 8:30 am1208 views The fossilized insect is tiny and its genital capsule, called a pygophore, is roughly the length of a grain of rice. It is remarkable, scientists say, because the bug’s physical characteristics – from the bold banding pattern on its legs to the internal features of its genitalia – are clearly visible and well-preserved. Recovered from the Green River Formation in present-day Colorado, the fossil represents a new genus and species of predatory insects known as assassin bugs.Latch, load and release: Elastic motion makes click beetles click, study findsJan 18, 2021 2:00 pm1525 views Click beetles can propel themselves more than 20 body lengths into the air, and they do so without using their legs. While the jump’s motion has been studied in depth, the physical mechanisms that enable the beetles’ signature clicking maneuver have not. A new study examines the forces behind this super-fast energy release and provides guidelines for studying extreme motion, energy storage and energy release in other small animals like trap-jaw ants and mantis shrimps.Pollinators not getting the 'buzz' they need in news coverageJan 13, 2021 8:45 am841 views A dramatic decline in bees and other pollinating insects presents a threat to the global food supply, yet it’s getting little attention in mainstream news, says a new University of Illinois Urbana-Champaign study. The research is based on a search of millions of news items in the university’s Global News Index, a unique database that draws from thousands of global news sources and decades of their publications.Study: Religion, psychology share methods for reducing distressJan 8, 2021 9:00 am1720 views Religious people facing life crises rely on emotion-regulation strategies that psychologists also use, a new study finds. They look for positive ways of thinking about hardship, a practice known to psychologists as “cognitive reappraisal.” They also tend to have confidence in their ability to cope with difficulty, a trait called “coping self-efficacy.” Both have been shown to reduce symptoms of anxiety and depression.Retracted scientific paper persists in new citations, study findsJan 5, 2021 9:00 am1229 views Information sciences professor Jodi Schneider is leading an effort to prevent the spread of retracted research.What happens when the coronavirus mutates?Jan 5, 2021 8:15 am3592 views New mutations to the coronavirus that causes COVID-19 are emerging, including a more-infectious variant first found in the United Kingdom, even as vaccines containing bits of viral genetic material are beginning distribution.
