School closures disproportionately hit disadvantaged students in the US

A study analyzing the distribution of school closures due to COVID concludes that racial minorities, students in need and with already poor academic performance have been more likely engaged in remote schooling since September 2020

2021-03-26
(Press-News.org) The uneven distribution of school closures in the US since September 2020 threatens to exacerbate regional, racial and class-based divides in educational performance, according to research by Zachary Parolin, of Bocconi University's Department of Social and Political Science, recently published in Nature Human Behavior. For example, in October, only 35% of White students were on distance learning, compared with 52% of Black students, 60% of Hispanic students and 65% of Asian students. And schools recording the lowest math scores were 15% more likely to be closed.

Professor Parolin and Emma Lee (Columbia University) found in fact that exposure to distance learning from September through December 2020 was more common among schools with lower academic performance (measured with third-grade math scores), a higher share of students experiencing homelessness, more students eligible for free/reduced-price lunches and from racial/ethnic minorities.

"If the schools and students with the greatest pre-COVID disadvantages are also those most exposed to school closures and distance learning, inequalities in learning outcomes may worsen," Professor Parolin says. Recent studies have demonstrated, in fact, that distance learning is less effective than traditional schooling, and that reductions in test scores appear to be particularly steep for students with less educated parents.

The authors measured in-person attendance using an anonymized mobile-phone database able to track traffic around locations, which covers 94% of US school districts and 98% of counties. A school was identified as "closed" or "mostly closed" if it experienced a 50% year-over-year decline in in-person visits during a given month.

"The race/ethnicity and math score gaps are particularly striking," Parolin and Lee write. "In October, 35% of White students were exposed to distance learning, compared with 52% of Black students, 60% of Hispanic students and 65% of Asian students. Moreover, schools recording the lowest third-grade math scores prior to the pandemic were, on average, around 15 percentage points more likely to be closed during September to December 2020 relative to schools with average test scores."

Disparities seem to be mainly driven by geography: larger and denser cities are both at greater risk of COVID spread and more diverse in population, while rural and less populated areas are more frequently white. Politics can also play a role, as Democrats (in power in denser, race-mixed areas, such as California or Washington DC) tended to be more rigorous in COVID restrictions than Republicans.

"The results of the study don't imply we are taking position on whether schools should close", Prof. Parolin warns. "School closures may save lives if they prevent the spread of COVID and the decision to turn to distance learning is undoubtedly difficult. Our study only observes that closures may be widening the educational gap."

Eat me: The cell signal of death
2021-03-26
Scientists at the Institute for Integrated Cell-Material Sciences (iCeMS) and colleagues in Japan have revealed molecular mechanisms involved in eliminating unwanted cells in the body. A nuclear protein fragment released into the cytoplasm activates a plasma membrane protein to display a lipid on the cell surface, signalling other cells to get rid of it. The findings were published in the journal Molecular Cell. "Every day, ten billion cells die and are engulfed by blood cells called phagocytes. If this didn't happen, dead cells would burst, triggering an auto-immune reaction," explains iCeMS biochemist Jun Suzuki, who led the study. "It is important to understand how dead cells are eliminated as part of our body's maintenance." Scientists ...

Intensity of tropical cyclones is probably increasing due to climate change

2021-03-26
Many tropical cyclone-prone regions of the world are expected to experience storm systems of greater intensity over the coming century, according to a review of research published today in ScienceBrief Review. Moreover, sea level rise will aggravate coastal flood risk from tropical cyclones and other phenomena, even if the tropical cyclones themselves do not change at all. Models also project an increase in future tropical-cyclone precipitation rates, which could further elevate the risk of flooding. Researchers at Princeton University, the U.S. National Oceanic and Atmospheric Administration (NOAA), and the University of East Anglia (UEA) examined more than 90 peer-reviewed articles to assess whether human activity is influencing ...

New genetic clues point to new treatments for 'silent' stroke

2021-03-26
Scientists have identified new genetic clues in people who've had small and often apparently 'silent' strokes that are difficult to treat and a major cause of vascular dementia, according to research funded by the British Heart Foundation (BHF) and published in The Lancet Neurology. Researchers discovered changes to 12 genetic regions in the DNA of people who have had a lacunar stroke - a type of stroke caused by weakening of the small blood vessels deep within the brain. Over time, damage to the blood vessels and subsequent interruption to blood flow can lead to long-term disability, causing difficulty with thinking, memory, walking and ultimately ...

Researchers harvest energy from radio waves to power wearable devices

Researchers harvest energy from radio waves to power wearable devices
2021-03-25
From microwave ovens to Wi-Fi connections, the radio waves that permeate the environment are not just signals of energy consumed but are also sources of energy themselves. An international team of researchers, led by Huanyu "Larry" Cheng, Dorothy Quiggle Career Development Professor in the Penn State Department of Engineering Science and Mechanics, has developed a way to harvest energy from radio waves to power wearable devices. The researchers recently published their method inMaterials Today Physics. According to Cheng, current energy sources for wearable health-monitoring devices have their place in powering sensor devices, but each has its setbacks. Solar power, for example, can only harvest energy when exposed to the sun. A self-powered triboelectric device can only ...

A T-cell stimulatory protein and interleukin-10 synergize to prevent gut inflammation

A T-cell stimulatory protein and interleukin-10 synergize to prevent gut inflammation
2021-03-25
BIRMINGHAM, Ala. - Researchers have found an unexpected synergy between a T-cell stimulatory protein -- the ICOS ligand -- and interleukin-10, an immunoregulatory cytokine, to prevent inflammatory bowel disease in mice. The study will aid the understanding of, and future research into, this immune disorder, which includes Crohn's disease and ulcerative colitis. About 1.6 million Americans have inflammatory bowel disease. Interleukin-10, or IL-10, was already known as a major player to prevent gut inflammation by establishing and maintaining immune homeostasis in the gut, where it is vital for the host to have a peaceful coexistence with normal intestinal microbes, while the immune system still stands ...

Turning wood into plastic

2021-03-25
Efforts to shift from petrochemical plastics to renewable and biodegradable plastics have proven tricky -- the production process can require toxic chemicals and is expensive, and the mechanical strength and water stability is often insufficient. But researchers have made a breakthrough, using wood byproducts, that shows promise for producing more durable and sustainable bioplastics. A study published in Nature Sustainability, co-authored by Yuan Yao, assistant professor of industrial ecology and sustainable systems at Yale School of the Environment (YSE), outlines the process of deconstructing the porous matrix of natural wood into a slurry. The researchers say the resulting material shows ...
