Hidden symmetry could be key to more robust quantum systems, researchers find
Researchers have found a way to protect highly fragile quantum systems from noise, which could aid in the design and development of new quantum devices, such as ultra-powerful quantum computers.
Dogs may never learn that every sound of a word matters
Despite their excellent auditory capacities, dogs do not attend to differences between words that differ only in one phoneme (e.g., "dog" vs "dig"), according to a new study by Hungarian researchers of the Eötvös Loránd University, Budapest (ELTE). In the study, they measured brain activity with non-invasive electroencephalography (EEG) on conscious dogs. This might be a reason why the number of words dogs learn to recognize typically remains low throughout their life. The study is published in Royal Society Open Science.

Steep rise in depressive symptoms among 7-12 year olds during UK-wide lockdown
The prevalence of depressive symptoms rose substantially among young children during the UK-wide lockdown in response to the first wave of the coronavirus pandemic, finds research focusing on one region of England and published online in Archives of Disease in Childhood.
Healthcare workers 7 times as likely to have severe COVID-19 as other workers
Healthcare workers are 7 times as likely to have severe COVID-19 infection as those with other types of 'non-essential' jobs, finds research focusing on the first UK-wide lockdown and published online in the journal Occupational & Environmental Medicine.
Capsule with asteroid samples arrives in Japan for research
Japanese space agency officials were delighted Tuesday by the return of a small capsule containing asteroid soil samples obtained by their Hayabusa2 spacecraft and they are anxiously waiting to look inside after preparations are complete.
China, Nepal say Everest a bit higher than past measurements
China and Nepal have jointly announced a new height for Mount Everest, ending a discrepancy between the two nations.
Researchers study the effects of parental job loss on families during the pandemic
A team of UTSA researchers has discovered that economic implications because of COVID-19 can have a devastating ripple effect on children. Monica Lawson, assistant professor of psychology, Megan Piel, assistant professor of social work and Michaela Simon, psychology graduate student in the UTSA College for Health, Community and Policy, have recently published a research article on the effects of parental job loss during the COVID-19 pandemic and risk of psychological and physical abuse toward children.
Britain starts virus vaccinations as California locks down
A pensioner became the first person to get the newly approved coronavirus jab on Tuesday, as a long-awaited vaccine roll-out began in Britain.
Research brief: Global trends in nature's contributions to people
In a new study published today in the Proceedings of the National Academy of Sciences, a research team co-led by the University of Minnesota, examined the risks to human well-being and prosperity stemming from ongoing environmental degradation.
Beavers may help amphibians threatened by climate change
The recovery of beavers may have beneficial consequences for amphibians because beaver dams can create the unique habitats that amphibians need.
Two discoveries advance basic and applied additive manufacturing research
A research team led by Tao Sun, associate professor of materials science and engineering at the University of Virginia, has made two discoveries that can expand additive manufacturing in aerospace and other industries that rely on strong metal parts.
Travel restrictions must be used in a targeted way to be effective at controlling local COVID-19 transmission: study
The measures may have limited impact on the epidemic within individual countries except those with low levels of the virus or that have strong travel links with countries experiencing high rates of infection.
Microbes to demonstrate biomining of asteroid material aboard space station
As humanity moves closer to the possibility of living and working millions of miles from Earth on planets like Mars, scientists are looking beyond our planet at how to acquire the materials needed to establish a self-sustaining presence in space.
Science leaders issue clarion call for evidence-based policy
Since the early days of the COVID-19 pandemic, US science leaders and others have expressed frustration with the lack of an informed and coherent federal response, a sentiment that echoes objections to the handling of other pressing issues, such as climate change. Writing in BioScience, an assemblage of the past presidents of the American Institute of Biological Sciences (AIBS) have issued an appeal for the reinvigoration of sound policy and governance through the careful consideration of sound science.
Scientists discover how COVID-19 virus causes multiple organ failure in mice
UCLA researchers are the first to create a version of COVID-19 in mice that shows how the disease damages organs other than the lungs. Using their model, the scientists discovered that the SARS-CoV-2 virus can shut down energy production in cells of the heart, kidneys, spleen and other organs.
Large US study confirms COVID-19 complications: Lung, kidney and cardiovascular issues
A large study of patients in the United States who contracted coronavirus disease 2019 (COVID-19) confirms many complications of the disease, according to new research in CMAJ (Canadian Medical Association Journal).
Natural reward theory could provide new foundation for biology
A link between evolution over short time frames (microevolution) and long time frames (macroevolution) that could open new approaches to understanding some of biology's deepest questions is proposed by Dr. Owen Gilbert of the Department of Integrative Biology at the University of Texas at Austin (U.S.) in a new paper, published in the open-access, peer-reviewed journal Rethinking Ecology.
Study identifies links between atopic dermatitis and autoimmune diseases
In a recent study published in the British Journal of Dermatology, individuals with atopic dermatitis, or eczema, were more likely to also have various autoimmune diseases, especially those involving the skin, the gastrointestinal tract, or the connective tissue.
Career thoughts and parental relationships in adolescents with ADHD
A new study published in The Career Development Quarterly looked for potential links between negative or dysfunctional career thoughts and the quality of parental relationships in high school students with attention-deficit/hyperactivity disorder (ADHD).
Most U.S. social studies teachers feel unprepared to teach civic learning
Only one in five social studies teachers in U.S. public schools report feeling very well prepared to support students' civic learning, saying they need additional aid with instructional materials, professional development and training, according to a RAND Corporation survey.
Digital stethoscope uses artificial intelligence for diagnosing lung abnormalities
Stethoscopes are a ubiquitous and cost-effective tool for medical diagnosis, but they open the door to subjectivity and can experience high levels of environmental noise. This makes it difficult to properly diagnose lung abnormalities, like COVID-19, by listening to sounds from the body.
What are schools doing to feed students during COVID-19-related closures?
As schools across the United States are grappling with remote and hybrid learning due to the COVID-19 pandemic, a new study in the Journal of Nutrition Education and Behavior, investigates the initial responses of child nutrition administrative agencies in all 50 US states and the District of Columbia (DC), five US territories, and the US Department of Interior Bureau of Indian Education (BIE).
