Researchers examined the characteristics and qualifications of the STEM teacher workforce in high-need schools in the U.S. and how they have evolved over nearly 30 years of national workforce surveys. The study primarily used high-poverty schools as the lens for examining differences in STEM teacher qualifications and characteristics over time.
In this week’s Physics of Fluids, researchers study how Champatis roll and bounce down inclines. The authors released a heap of the seeds down an inclined plane while a camera recorded their descent to analyze their speed and the dynamics of their movement. The grains start to spread out slowly, then decrease quickly as they move downstream, akin to rock avalanches.
In this week’s Physics of Fluids, researchers employ machine learning to more accurately model the boundary layer wind field of tropical cyclones. Conventional approaches to storm forecasting involve large numerical simulations run on supercomputers incorporating mountains of observational data, and they still often result in inaccurate or incomplete predictions. In contrast, the author’s machine learning algorithm is equipped with atmospheric physics equations that can produce more accurate results faster and with less data.
Up until recently, habituation — a simple form of learning — was deemed the exclusive domain of complex organisms with brains and nervous systems, such as worms, insects, birds, and mammals. But a new study, published Nov. 19 in Current Biology, offers compelling evidence that even tiny single-cell creatures such as ciliates and amoebae, as well as the cells in our own bodies, could exhibit habituation akin to that seen in more complex organisms with brains.
Researchers have found that some coronavirus genes don’t produce a working protein, but nevertheless appear evolutionarily advantageous. Their work investigating how these mystery genes evolve could help forecast which viral variants might be more dangerous.
A group of investigators led by Cedars-Sinai have developed and successfully tested a new artificial intelligence (AI) method to make launching cancer clinical trials easier and faster.
A few years back, a group of weed scientists showed that soil-applied herbicides are less effective against agricultural weeds in the context of our changing climate. Now, the same research group, led by the USDA Agricultural Research Service and the University of Illinois Urbana-Champaign, has shown the same is true of post-emergence (POST) herbicides.
Case Western Reserve University President Eric W. Kaler and Provost Joy K. Ward announced that David Gerdes, a renowned physics scholar and department chair from University of Michigan, will become dean of the College of Arts and Sciences on March 1. Gerdes, the Arthur F. Thurnau Professor of Physics and a professor of astronomy, has served on the University of Michigan faculty since 1998 and as chair of the physics department since 2019.
A new study from the University of Georgia suggests that users value the unique virtual interactions with others offered by digital events in the metaverse.
Latinos who rely on Spanish-language social media for news were 11-20 percentage points more likely to believe false political narratives, finds study from NYU and UC San Diego.
