When nature vanishes, people of color and low-income Americans disproportionally lose critical environmental and health benefits--including air quality, crop productivity and disease control--a new study in Nature Communications finds. The research is the first national study to explore the unequal impacts on American society--by race and income--of projected declines in nature and its benefits. Researchers find multiple natural benefits will drop for people of color by an average of 224%-111% between 2020-2100, as white communities see gains.
For older adults, participating in social activities can protect against physical and mental signs of aging, but it may also pose risks, especially for women.
Researchers from York University and the University of British Columbia have found social media use to be one of the factors related to the spread of COVID-19 within dozens of countries during the early stages of the pandemic. The researchers say this finding resembles other examples of social media misinformation ranging from the initial phase of vaccine rollout to the 2021 Capitol riot in the United States.
Previous research suggests that COVID-19 has disproportionately affected some demographic groups. A new analysis using more individual-level data and including both inpatients and outpatients confirms a large role of structural factors. Data indicates striking disparities in the pandemic's impact.
Research from the University of Pennsylvania's Allyson Mackey and graduate student Cassidy McDermott shows that children from lower-income backgrounds and those who go through greater adverse childhood experiences get their first permanent molars sooner. The findings align with a broader pattern of accelerated development often seen under conditions of early-life stress.
New research shows transmission of the virus behind COVID-19 varies seasonally, but warmer conditions are not enough to prevent transmission.
Researchers explored suicide trends by firearms in white and black Americans ages 5 to 24 years from 1999 to 2018. From 2008 to 2018, rates of suicide by firearms quadrupled in those ages 5 to 14 years and increased by 50% in those ages 15 to 24 years. Suicide deaths by firearms were more prevalent in white than black Americans -- a marked contrast with homicide by firearms, which are far more prevalent in black than white Americans.
Real-world data from Sleep Number® smart bed sleepers shows a potential model for predicting and tracking COVID-19 infection using sleep and biometric measures. Analysis of 18.2 million 360 smart bed sleep sessions finds heart rate variability differs with age, gender and day of the week.
As many older adults get back to normal life across the United States thanks to high rates of vaccination and lower COVID-19 activity, a new poll suggests many should watch their alcohol intake.
New research reveals that only a minority of U.S. Medicare beneficiaries with knee osteoarthritis in 2005-2010 used non-surgical care such as physical therapy and knee injections, and few were treated by rheumatologists, physiatrists, or pain specialists. The study, which is published in Arthritis & Rheumatology, also found that non-surgical care was more common in regions with low rates of knee replacement surgery.
