A new study published by researchers from the University of Oxford, the Wildlife Conservation Society (WCS), CIFOR-ICRAF, and institutional partners reveals a disconnect between media and public perceptions on the risks of consuming wild meat in Central Africa during COVID-19 and sheds light on the complex relationship between media reporting, community beliefs, and behaviour change — offering important lessons for wildlife management and public health strategies.
A study comparing the effects of SARS-CoV-2 infection in lean and obese primates found different long-term consequences of the virus depending on prior obesity and metabolic disease. The results, which also highlighted how widespread long COVID symptoms are in animals, were published July 24th in the open-access journal PLOS Pathogens by Charles Roberts of Oregon Health & Science University, USA, and colleagues.
Over 950 billion (about 3.8 million tons) masks have been consumed in the last four years around the world to protect human beings from COVID-19 and air pollution. However, very few of these used masks are being recycled, with the majority of them being landfilled or incinerated. To address this issue, we propose a repurposing upcycling strategy by converting these polypropylene (PP)-based waste masks to high-performance thermally conductive nanocomposites (PP@G, where G refers to graphene) with exceptional electromagnetic interference shielding property. The PP@G is fabricated by loading tannic acid onto PP fibers via electrostatic self-assembling, followed by mixing with graphene nanoplatelets (GNPs). Because this strategy enables the GNPs to form efficient thermal and electrical conduction pathways along the PP fiber surface, the PP@G shows a high thermal conductivity of 87 W m-1 K-1 and exhibits an electromagnetic interference shielding effectiveness of 88 dB (1100 dB cm-1), making it potentially applicable for heat dissipation and electromagnetic shielding in advanced electronic devices. Life cycle assessment and techno-economic assessment results show that our repurposing strategy has significant advantages over existing methods in reducing environmental impacts and economic benefits. This strategy offers a facile and promising approach to upcycling/repurposing of fibrous waste plastics.
Infants, toddlers and preschoolers exhibit symptoms of long COVID, but the symptoms can be different and more difficult to identify in these children, according to Rutgers Health research.
The new study is part of the National Institutes of Health–funded Researching COVID to Enhance Recovery (RECOVER) initiative and published in the Journal of the American Medical Association Pediatrics.
A new study, led by experts at the University of Nottingham, has found that the Covid-19 pandemic may have accelerated people’s brain health, even if they were never infected with the virus.
They affect up to 50% of patients who have had an infection requiring hospitalization. An international consensus statement has been drawn up for radiologists to harmonize the management of post-COVID patients. The lead author is a radiologist from Università Cattolica at Rome campus, Italy
As the latest wave of COVID-19 shows no signs of abating, University of South Australia experts say it’s not just booster shots that could offer protection – healthy levels of vitamin D may also play a role.
Increased attention has been focused on the mental health of American children following the challenges posed by the COVID-19 pandemic. A survey of public school principals finds that nearly one-third of the nation’s K-12 U.S. public schools mandate mental health screening for students, with most offering in-person treatment or referral to a community mental health professional if a student is identified as having depression or anxiety.
