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 am1046 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 pm1446 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 am909 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.

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 am18827 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 am3132 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 am1250 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 am1670 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 am2472 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 am1098 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.

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 am531 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 pm457 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 pm649 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 am796 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 am1622 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 pm1118 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 am570 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.
