Prospective teachers appear more likely to misperceive Black children as angry than white children, which may undermine the education of Black youth, according to new research published by the American Psychological Association.
The bad news, not that anyone needs more of it: The dangers of COVID-19 could worsen if misinformation on social media continues to spread unchecked. Essentially, what people choose to share on social media about the pandemic could become a life-or death decision.
The good news? Though there is no practical way to fully stem the tide of harmful misinformation on social media, certain tactics could help improve the quality of information that people share online about this deadly disease.
In sufferers of Parkinson's disease, clumps of α-synuclein (alpha-synuclein), sometimes known as the 'Parkinson's protein', are found in the brain. These destroy cell membranes, eventually resulting in cell death. Now, a new method developed at Chalmers University of Technology, Sweden, reveals how the composition of cell membranes seems to be a decisive factor for how small quantities of α-synuclein cause damage.
Specific sleep problems among babies and very young children can be linked to mental disorders in adolescents, a new study has found.
A team at the University of Birmingham's School of Psychology studied questionnaire data from the Children of the 90s, a UK-based longitudinal study which recruited pregnant mothers of 14,000 babies when it was set up almost three decades ago.
Washington, DC-- You've heard the expression form follows function? In materials science, function follows form.
New research by Carnegie's Olivier Gagné and collaborator Frank Hawthorne of the University of Manitoba categorizes the causes of structural asymmetry, some surprising, which underpin useful properties of crystals, including ferroelectricity, photoluminescence, and photovoltaic ability. Their findings are published this week as a lead article in the International Union of Crystallography Journal.
PITTSBURGH--Researchers at Carnegie Mellon University have demonstrated that they can combine iPhone videos shot "in the wild" by separate cameras to create 4D visualizations that allow viewers to watch action from various angles, or even erase people or objects that temporarily block sight lines.
Imagine a visualization of a wedding reception, where dancers can be seen from as many angles as there were cameras, and the tipsy guest who walked in front of the bridal party is nowhere to be seen.
Biomacromolecules incorporated into tailored metal-organic frameworks using peptide modulators are well shielded but highly active thanks to carefully tuned nanoarchitecture. As scientists report in the journal Angewandte Chemie, this strategy can be used to synthesize an "artificial cell" that functions as an optical glucose sensor.
With a specialised telescope in Namibia a DESY-led team of researchers has proven a certain type of binary star as a new kind of source for very high-energy cosmic gamma-radiation. Eta Carinae is located 7500 lightyears away in the constellation Carina (the ship's keel) in the Southern Sky and, based on the data collected, emits gamma rays with energies all the way up to 400 gigaelectronvolts (GeV), some 100 billion times more than the energy of visible light.
Currently, there are no specific guidelines on the most effective materials and designs for facemasks to minimize the spread of droplets from coughs or sneezes to mitigate the transmission of COVID-19. While there have been prior studies on how medical-grade masks perform, data on cloth-based coverings used by the vast majority of the general public are sparse.
With graduation ceremonies, weddings, funeral, annual parades, and many other gatherings called off, it is apparent that our lives are filled with rituals. UConn Assistant Professor of Anthropology Dimitris Xygalatas studies rituals and how they impact our health. In research published today in Philosophical Transactions of the Royal Society, Xygalatas and collaborators from Masaryk University, Czech Republic, including former UConn student Martin Lang, examine the important roles rituals play in reducing our anxiety levels.
LAWRENCE -- New information emerges about the novel coronavirus on a daily basis, sometimes confirming, other times contradicting what we thought we knew the day before. Our reaction to this constant information flow depends not only on our understanding of the COVID-19 pandemic but also our sources, environment and how we estimate risk. A recent University of Kansas study found that while Kansas survey participants relied on multiple sources about reliable COVID-19 information, they tended to prefer local authorities and distrust social media.
Light to moderate drinking may preserve brain function in older age, according to a new study from the University of Georgia.
The study examined the link between alcohol consumption and changes in cognitive function over time among middle-aged and older adults in the U.S.
"We know there are some older people who believe that drinking a little wine everyday could maintain a good cognitive condition," said lead author Ruiyuan Zhang, a doctoral student at UGA's College of Public Health.
New Zealand's monster penguins that lived 62 million years ago had doppelgangers in Japan, the USA and Canada, a study published today in the Journal of Zoological Systematics and Evolutionary Research has found.
Scientists have identified striking similarities between the penguins' fossilised bones and those of a group of much younger Northern Hemisphere birds, the plotopterids.
These similarities suggest plotopterids and ancient penguins looked very similar and might help scientists understand how birds started using their wings to swim instead of fly.
Long-term morbidity as well as a lower level of education and employment rate are common among adults who underwent congenital heart surgery during childhood, regardless of the severity of the defect.
A congenital heart defect in childhood increases the risk of chronic diseases, such as arrhythmia and heart failure, in adulthood. The risk of other diseases, including asthma, epilepsy and even psychiatric diseases, is also higher than usual. These adverse effects occur regardless of the severity of the heart defect.
ANN ARBOR, Mich. - Kindergartners in face masks. Closed playground structures. Random COVID-19 testing.
They are among the long list of hypothetical scenarios for school in the pandemic era.
And as lawmakers and educators reimagine the K-12 model for fall, a new survey assessed parents' plans for in-person school and support for 15 potential measures to reduce the risk of COVID-19 in schools in Illinois, Michigan, and Ohio.
