When parents are under stress, household rules about screen time often get abandoned, new University of Guelph research finds.
A first of its kind in Canada, the study found parents of young children reporting high levels of life or parenting stress were less likely to monitor and limit their kids' screen use and more likely to use their own devices in front of their children.
The COVID-19 pandemic threatens the survival of organizations nationwide that provide critical outdoor environmental and science education to K-12 students, with an alarming 63% of such groups uncertain about their ability to ever reopen their doors, according to a study released this week by the Lawrence Hall of Science at the University of California, Berkeley.
If past hospitalizations for pneumonia and other respiratory illnesses are any guide, many Americans could face high out-of-pocket medical costs for COVID-19 hospitalizations despite the fact that many insurers have waived their cost-sharing requirements, a study from researchers at Johns Hopkins Bloomberg School of Public Health suggests.
Picture 500 million cars stacked in rows. That's how much carbon--about 1,000 petagrams, or one billion metric tons--is locked away in Arctic permafrost.
Currently, scientists estimate that 5-15% of the carbon stored in surface permafrost soils could be emitted as the greenhouse gas carbon dioxide by 2100, given the current trajectory of global warming. This emission, spurred by microbial action, could lead to 0.3 to 0.4 degrees Celsius of additional global warming.
While crop diseases have devastating consequences on agriculture, causing losses of up to 30% in some crops, plants constantly evolve to maintain robust immune systems that allow them to perceive pathogens and develop defenses. One key player in this system is the plant cell wall, a complex structure that surrounds all plant cells. The plant cell wall is a dynamic structure modified by interactions with microbes and environmental stresses. These modifications alter the integrity of the cell wall and often activate plant immunity and disease resistance responses.
One in four households with children have reported a child experiencing hunger as a result of the COVID-19 health crisis, according to the latest CUNY SPH COVID-19 tracking survey. Many New Yorkers continued to report difficulties in getting the food they needed, but of particular concern is the impact on households with children under the age of 18. About one in three of these households reported that since the epidemic started a child had lost weight and almost one in four reported that a child had been hungry because they couldn't get enough food to feed them.
Imagine Earth completely covered in ice. While it's hard to picture all of today's oceans and land masses obscured with glaciers, such an ice-covered version of the planet was not so far-fetched millions of years ago.
Lasting from approximately 1,000 to 540 million years ago, the dramatic chapter is an important part of Earth's 4.5-billion-year history. Known as the Neoproterozoic Era, the period of severe glaciation was a time when multicellular organisms were beginning to diversify and spread across the planet.
June 15, 2020 -- The complex food shopping patterns that financially insecure families employ have been upended by the COVID-19 crisis. While increasing the maximum benefit for the Supplemental Nutrition Assistance Program (SNAP, formerly Food Stamps) is an essential step in addressing the current food insecurity crisis, this policy change alone will not address many of the barriers low-income families are facing in acquiring food during the pandemic.
Sophia Antipolis - 15 June 2020: Use the right tool for the job. Today experts outline the best way to identify people most likely to develop common and devastating heart rhythm disorders. The advice is published in EP Europace,1 a journal of the European Society of Cardiology (ESC) and presented on EHRA Essentials 4 You, a scientific platform of the ESC.
One of the biggest and longest-standing questions in the history of human thought is whether there are other intelligent life forms within our Universe. Obtaining good estimates of the number of possible extraterrestrial civilizations has however been very challenging.
Durham, NC - Results of a study released today in STEM CELLS Translational Medicine (SCTM) may point the way to a cure for a serious lung disease called silicosis that affects millions of workers worldwide. Silicosis results from years of breathing in dust microparticles of silica by workers in professions such as construction and sand blasting. The particles can eventually lead to inflammation and scarring of the lung tissue, which in turn makes it difficult to breathe and can result in death.
COLUMBUS, Ohio - Political candidates' use of humor on social media could sometimes backfire on them with potential supporters, new research suggests.
People were more likely to view messages using humor as inappropriate for a political candidate they didn't know, the study found. That led participants to rate a candidate using humor as less credible than one who didn't - and less likely to get their vote.
In the fight against cancer or chronic infections, the immune system must be active over long periods of time. However, in the long run, the immune defence system often becomes exhausted. Scientists at the German Cancer Research Center (DKFZ) have now found initial evidence in mice that skeletal muscles help to keep the immune system functional in chronic diseases.
In a sign that designer drugs are becoming more prevalent in Australia, synthetic cathinones - commonly known as 'bath salts' - have been detected in the nation's wastewater in the largest study of its kind in the country.
These emerging family of drugs mimic the effects of ecstasy and amphetamines are among 15 new psychoactive substances (NPS) found in a study of Australia's metropolitan and regional wastewaters over the past three years.
Tokyo, Japan - Type 1 diabetes mellitus (T1DM) results from an irreversible autoimmune destruction of insulin-producing pancreatic β-cells requiring life-long substitution of insulin. In a new study, researchers at the Institute of Industrial Science, The University of Tokyo discovered that the diameter of cell-laden hydrogels determines its longevity after transplantation, paving the way for efficacious cell therapy for T1DM.
