An online education model in Russia in which national platforms license STEM (science, technology, engineering, and mathematics) courses from top universities to institutions with instructor shortages could significantly lower instruction costs, allowing resource-constrained universities to enroll more STEM students, according to a new study.

High-quality online courses are no less effective than traditional classes when it comes to student learning outcomes. Online courses provide an opportunity to expand access to high-quality education without increasing costs: the number of students that universities will be able to enroll increases by 15-18%. The results of a study carried out jointly by HSE University researchers and US researchers have been published in Science Advances.

BUFFALO, N.Y. -- Personal growth and job skills have taken a backseat to an increased focus on standardized test scores in schools across the nation, according to new University at Buffalo-led research.

The study, which analyzed the educational goals of principals at thousands of public, private and charter schools over two decades, found the shift in priorities is most pronounced in public schools.

The ability to generate light pulses of sub-femtosecond duration, first demonstrated some 20 years ago, has given rise to an entirely new field: attosecond science and technology. Table-top laser systems have emerged that enable studies that for decades were but a distant dream --- to follow, image and characterise electronic processes in atoms, molecules and solids on their natural, attosecond timescales. The laser systems that make such studies possible typically operate in the extreme ultraviolet spectral band. There has long been a push to achieve higher photon energies though.

ITHACA, N.Y. - Students learned just as much in online STEM college courses as they did in traditional classroom settings, and at a fraction of the cost, according to a first-of-its-kind study.

What The Study Did: The case of a patient with coronavirus disease 2019 (COVID-19) whose main symptom was a loss of smell without nasal obstruction is reported in this article.

Authors: Michael Eliezer, M.D, of Lariboisière University Hospital in Paris, is the corresponding author.

New research published in Academic Emergency Medicine indicates that for physicians and nurses working evening shifts in the emergency department, interacting with a therapy dog for several minutes may help lower stress.

What The Study Did: This survey study assessed public concerns about symptoms of coronavirus disease 2019 and individual actions in response to the pandemic.

The majority of New York City residents expect a long disruption to their daily life. While a quarter (25%) think the epidemic will disrupt their life for less than a month, 27% think its impact will last two months, 20% three months, and a substantial plurality, 28%, anticipate more than four months' disruption. The findings are part of the fourth weekly city and statewide tracking survey from CUNY Graduate School of Public Health & Health Policy (CUNY SPH), conducted April 3-5.

The brain is permanently exposed to new impressions. Even when sleeping, it does not rest and processes recent experiences. In very early childhood, it has been thought that sleep primarily promotes semantic memory. This includes general knowledge such as the meaning of words.

April 07, 2020-- Researchers have identified the most common clinical characteristics of 109 patients with COVID-19 related pneumonia who died in Wuhan, China in the early stages of the coronavirus pandemic, according to a new study published online in the Annals of the American Thoracic Society.

Washington, D.C., April 7, 2020 -- In states that have banned affirmative action, the share of underrepresented minorities among students admitted to and enrolling in public universities has steadily lost ground relative to changing demographic trends among those states' high school graduates, according to new research.

The study, by Mark Long at the University of Washington and Nicole Bateman at the Brookings Institution, was published today in Educational Evaluation and Policy Analysis, a peer-reviewed journal of the American Educational Research Association.

College students who listened to classical music by Beethoven and Chopin during a computer-interactive lecture on microeconomics -- and heard the music played again that night -- did better on a test the next day than did peers who were in the same lecture, but instead slept that evening with white noise in the background.

Global climate change will affect fish sizes in unpredictable ways and, consequently, impact complex food webs in our oceans, a new IMAS-led study has shown.

Led by IMAS and Centre for Marine Socioecology scientist Dr Asta Audzijonyte and published in the journal Nature Ecology and Evolution, the study analysed three decades of data from 30 000 surveys of rocky and coral reefs around Australia.

An international panel of cancer experts has recommended a one-week course of radiotherapy and delaying surgery as the best way to treat patients with bowel cancer during the COVID-19 pandemic.

The short course of treatment involves higher-intensity radiation rather than five weeks of radiotherapy coupled with chemotherapy. Surgery, which normally happens one to two weeks after radiotherapy, can be safely delayed by up to 12 weeks, say the expert panel.
