Scientists at the Institute of Physics of the University of Tartu have found a way to develop optical quantum computers of a new type. Central to the discovery are rare earth ions that have certain characteristics and can act as quantum bits. These would give quantum computers ultrafast computation speed and better reliability compared to earlier solutions. The University of Tartu researchers Vladimir Hizhnyakov, Vadim Boltrushko, Helle Kaasik and Yurii Orlovskii published the results of their research in the scientific journal Optics Communications.
Liquids are ubiquitous in Nature: from the water that we consume daily to superfluid helium which is a quantum liquid appearing at temperatures as low as only a few degrees above the absolute zero. A common feature of these vastly different liquids is being self-bound in free space in the form of droplets. Understanding from a microscopic perspective how a liquid is formed by adding particles one by one is a significant challenge.
COLUMBIA, Mo. - When he was in middle school, teachers would give Sam Curran a list of words to type in a computer to practice his vocabulary. But Sam, who has autism, was unable to stay focused on the task and required a significant amount of one-to-one direction from a teacher to complete his work. After his mother, Alicia, persuaded his teachers to allow Sam to change the colors of the words, he was able to complete work more independently and began making remarkable progress.
MEDFORD/SOMERVILLE, Mass. (Jan. 14, 2021)-- Exposure to discrimination plays a significant role in the risk of developing anxiety and related disorders, even - in a first - after accounting for potential genetic risks, according to a multidisciplinary team of health researchers led by Tufts University and the Harvard T.H. Chan School of Public Health.
Researchers at the UC Davis Violence Prevention Research Program (VPRP) assessed the prevalence of exposure to violence, such as robbery or assault, and its impacts on the mental health and social functioning of California adults. Their study, published in the Journal of Interpersonal Violence, shows the far-reaching psychological effects an incident of gun violence can have on victims and those close to them.
Many students, especially non-science majors, dread chemistry. The first lesson in an introductory chemistry course typically deals with how to interpret the periodic table of elements, but its complexity can be overwhelming to students with little or no previous exposure. Now, researchers reporting in ACS' Journal of Chemical Education introduce an innovative way to make learning about the elements much more approachable -- by using "pseudo" periodic tables filled with superheroes, foods and apps.
COLUMBUS, Ohio - While we wait for our turn to get vaccinated against SARS-CoV-2, we could - and probably should - use the time to make sure we bring our healthiest emotional and physical selves to the treatment, a new review of previous research suggests.
Ohio State University researchers reviewed 49 vaccine studies in humans dating back 30 years that document how stress, depression and poor health behaviors can negatively affect the body's immune response to vaccination, and how improving health factors can enhance that response.
Decades of research show that depression, stress, loneliness, and poor health behaviors can weaken the body's immune system and lower the effectiveness of certain vaccines. A new report accepted for publication in Perspectives on Psychological Science suggests that the same may be true for the new COVID-19 vaccines that are in development and the early stages of global distribution. Fortunately, it may be possible to reduce these negative effects with simple steps like exercise and sleep.
Crowdsourced Responses from Dermatologists on Twitter Found to be as Effective as Formal Telemedicine
BOSTON - New research from Boston Medical Center finds that using clear, unambiguous language when recommending HPV vaccination both increases vaccine acceptance and increases conversation efficiency while preserving patient satisfaction.
Traditional gendered patterns of child care persisted during the COVID-19 shutdown, with more than a third of couples relying on women to provide most or all of it, according to a study from University of Georgia researcher Kristen Shockley.
Some previous research has found that typical familial patterns may get upended during crises, but that's not what Shockley and her colleagues found in the early months of the COVID-19 shutdown.
CLEVELAND--The combined effectiveness of three COVID-prevention strategies on college campuses--mask-wearing, social distancing, and routine testing--are as effective in preventing coronavirus infections as the Pfizer and Moderna vaccines approved by the U.S. Food and Drug Administration (FDA), according to a new study co-authored by a Case Western Reserve University researcher.
The research, published in Annals of Internal Medicine, has immediate significance as college semesters are poised to start again--and as the distribution of approved vaccines lags behind goals.
You are likely familiar with the serious consequences of anorexia for those who experience it, but you might not be aware that the disorder may not be purely psychological. A recent review from researchers at the University of Oxford in the open-access journal
Conflict between divorced or separated parents increases the risk of children developing physical and mental health problems.
A new study from the Arizona State University Research and Education Advancing Children's Health (REACH) Institute has found that children experience fear of being abandoned when their divorced or separated parents engage in conflict. Worrying about being abandoned predicted future mental health problems in children. The work will be published in Child Development on January 12.
Toronto (Jan. 12, 2021) - More than half the clinicians surveyed at the Peter Munk Cardiac Centre reported burnout and high levels of distress according to a series of studies published today in the Canadian Medical Association Journal Open (CMAJ-OPEN). In these studies carried out before the COVID-19 pandemic, 78% of nurses, 73% of allied health staff and 65% of physicians described experiencing burnout.
