Phys.org / Significant grade inflation may be occurring in graduate education, according to decades' worth of data
Analysis of two decades of student data at a large U.S. university suggests that grade inflation exists in graduate education. Researcher Vivien Lee and colleagues at the University of Minnesota, U.S., present these findings ...
Tech Xplore / Researchers use machine learning and social network theory to identify formation patterns in digital forums
Researchers at Stevens Institute of Technology used machine learning tools and social network theory—the study of how people connect with each other—to better understand how people interact online. Using data from X, formerly ...
Medical Xpress / Fiber in whole wheat foods protects against gut inflammation in mice, research finds
Enriching the diet with wheat fiber protects mice against intestinal inflammation, according to a study published by researchers at the Institute for Biomedical Sciences (IBMS) at Georgia State University. The finding helps ...
Phys.org / Cactus catalog could help plant's prickly problem
With almost a third of cacti species threatened with extinction, a new open-access database of cactus ecology and evolution could help scientists and conservationists save species from the brink.
Medical Xpress / Gut-to-brain pathway explains how the immune system triggers loss of appetite during parasitic infection
Anyone who has weathered a bad stomach bug knows the feeling: a loss of appetite that sets in and lingers, even after the initial illness. For the millions of people around the world who are chronically infected with parasitic ...
Phys.org / Low-cost sensor system could warn farmers of salt stress in plants
Soil salinity is a critical concern in agriculture when excessive soluble salts restrict a plant's water uptake, according to the U.S. Department of Agriculture, hindering crop growth and reducing yields on roughly 30% of ...
Medical Xpress / Simple blood tests may predict response to lymphoma treatment
Many people with an aggressive blood cancer called diffuse large B cell lymphoma are cured by the current gold standard of treatment: an antibody designed to wipe out cancerous B cells plus a combination of four chemotherapy ...
Phys.org / New antibiotic alternative fights foodborne Salmonella
Antimicrobial-resistant Salmonella poses severe challenges to global food safety and public health. Researchers from China have now identified a novel bacteriophage that offers a highly promising "green" biocontrol solution ...
Phys.org / Hooking big fish in warming oceans comes with a catch
When it comes to fishing, reeling in the biggest one is often the goal. But as it turns out, leaving the largest and oldest fish in the water can help entire fish populations cope better with ocean warming—and the benefits ...
Phys.org / DNA origami precisely positions single-photon emitters for quantum technologies
An international research team led by scientists from Skoltech has developed a method to position molecules on the surface of ultrathin materials with unprecedented precision using molecular DNA self-assembly, enabling the ...
Medical Xpress / How STING gets moving: Study identifies transport protein key to immune response
UT Southwestern Medical Center researchers have identified how the quintessential immune protein known as stimulator of interferon genes (STING) migrates from one cellular organelle to another, a necessary step in its activation. ...
Medical Xpress / New medicine piggybacks onto fat absorption pathways to allow oral delivery in major depressive disorder
Monash University and Seaport Therapeutics have developed a new approach to delivering drug molecules that piggybacks onto natural fat absorption pathways to allow oral delivery of some drugs previously requiring injection. ...
