UrduA new study at the University of Minnesota found students who attended large classes live via Zoom (synchronously) did better on exams than students who later watched recorded lectures (asynchronously), particularly when sex and ethnicity were considered.

To Better Understand Speech, Focus on Who Is Talking
Researchers have found that matching the locations of faces with the speech sounds they are producing significantly improves our ability to understand them, especially in noisy areas where other talkers are present. In the Journal of the Acoustical Society of America, they outline a set of online experiments that mimicked aspects of distracting scenes to learn more about how we focus on one audio-visual talker and ignore others.
Strategic Air Purifier Placement Reduces Virus Spread Within Music Classrooms
The University of Minnesota School of Music was concerned about one-on-one teaching during the COVID-19 pandemic and wondered if it should supplement its ventilation system with portable HEPA air purifiers. So, school officials reached out to Suo Yang, a professor within the College of Science and Engineering, and his team to figure it out. In Physics of Fluids, Yang and the researchers describe their work to predict how virus particles spread within a music classroom.
Advanced Simulations Reveal How Air Conditioning Spreads COVID-19 Aerosols
A restaurant outbreak in China was widely reported as strong evidence of airflow-induced transmission of COVID-19, but it lacked a detailed investigation about exactly how transmission occurred. In Physics of Fluids, researchers at the University of Minnesota report using advanced simulation methods to capture the complex flows that occur when the cold airflow from air conditioners interacts with the hot plume from a dining table and the transport of virus-loading particles within such flows.
National Science Foundation Funds Development of a Science Gateway for New Materials Discovery
The National Science Foundation has awarded a $1 million Research Advanced by
Interdisciplinary Science and Engineering (RAISE) grant to a multidisciplinary team of researchers at the San Diego Supercomputer Center (SDSC) at the University of California San Diego, the University of Minnesota, Carnegie Mellon University, and Cornell University to create the X-ray Imaging of Microstructures Gateway (XIMG), a science gateway designed to make it possible for global material sciences researchers to study the behavior of new and existing materials using X-ray diffraction.
High-Tech Printing May Help Eliminate Painful Shots
Painful hypodermic needles may not be needed in the future to give shots, inject drugs and get blood samples. With 4D printing, Rutgers engineers have created tiny needles that mimic parasites that attach to skin and could replace hypodermic needles, according to a study in the journal Advanced Functional Materials.
