Just how stressed are teachers? A recent Gallup poll found teachers are tied with nurses for the most stressful occupation in America today. Unfortunately, that stress can have a trickle-down effect on their students, leading to disruptive behavior that results in student suspensions.
One of those overburdened teachers is Jennifer Lloyd, a high school English teacher in Maryland and a graduate student at the University of Missouri. She has noticed how perceptive her students are to her mood and their ability to feed off of her energy, for better or worse.
INDIANAPOLlS - In a novel study the authors hope will contribute to improved patient care, Richard L. Roudebush Veterans Affairs Medical Center and Regenstrief Institute researchers examine how Black patients with mental health concerns evaluate verbal and non-verbal communication during treatment.
Ultraviolet light endangers the integrity of human genetic information and may cause skin cancer. For the first time, researchers of Karlsruhe Institute of Technology (KIT) have demonstrated that DNA damage may also occur far away from the point of incidence of the radiation. They produced an artificially modeled DNA sequence in new architecture and succeeded in detecting DNA damage at a distance of 30 DNA building blocks. The results are reported in Angewandte Chemie (DOI: 10.1002/anie.202009216).
Kanazawa, Japan - A team of scientists led by Kanazawa University proposed a new mathematical framework to understand the properties of the fundamental particles called neutrinos. This work may help cosmologists make progress on the apparent paradox of the existence of matter in the Universe.
Superconducting wires can transport electricity without loss. This would allow for less power production, reducing both costs and greenhouse gasses. Unfortunately, extensive cooling stands in the way, because existing superconductors only lose their resistance at extremely low temperatures. In the journal Angewandte Chemie, scientist have now introduced new findings about hydrogen sulfide in the H(3)S form, and its deuterium analogue D(3)S, which become superconducting at the relatively high temperatures of -77 and -107 °C, respectively.
LAWRENCE -- "She was totally flirting with you," my friend told me after the hosts left our table.
"No, she wasn't. She was just being polite," said another friend.
Misunderstandings about flirting can potentially result in awkwardness or even accusations of sexual harassment. How can we figure out what other people mean when they smile at us? Is there a unique, identifiable facial expression representing flirting -- and if there is, what does it convey, and how effective is it?
A potential response of river fish to environmental changes is to colonize new habitats. But what happens when dams and weirs restrict their movement? And are native and alien species similarly affected? Researchers from the Leibniz-Institute of Freshwater Ecology and Inland Fisheries (IGB) and the Spanish University of Girona (UdG) have addressed these questions in a recent study.
Scientists have shown that the babies of mothers dealing with anxiety or depression exhibit physiologically stronger signs of stress than babies of healthy mothers, when given a standard stress test. These babies show a significantly increased heart rate, which researchers fear may lead to imprinted emotional stresses as the child grows up.
Surgeons could dramatically reduce the risk of infection after an operation by simply changing the antiseptic they use.
New analysis by the University of Leeds and the University of Bern of more than 14,000 operations has found that using alcoholic chlorhexidine gluconate (CHG) halves the risk of infection in certain types of surgery when compared to the more commonly used povidone-iodine (PVI).
Infection after surgery could result in a range of issues including readmission to hospital and possibly further surgery.
Lasing - the emission of a collimated light beam of light with a well-defined wavelength (color) and phase - results from a self-organization process, in which a collection of emission centers synchronizes itself to produce identical light particles (photons). A similar self-organized synchronization phenomenon can also lead to the generation of coherent vibrations - a phonon laser, where phonon denotes, in analogy to photons, the quantum particles of sound.
The Human Molecular Genetics laboratory of the de Duve Institute (UCLouvain), headed by Professor Miikka Vikkula, recently identified mutations in a novel gene, ANGPT2, responsible for primary lymphedema. Together with the Wihuri Research Institute and it's director Professor Kari Alitalo at the University of Helsinki, Finland, the laboratories could show how these mutations cause the disease.
ST. LOUIS - A team of researchers led by Kenton Johnston, Ph.D., an associate professor of health management and policy at Saint Louis University's College for Public Health and Social Justice, conducted a study to investigate how outpatient clinicians that treated disproportionately high caseloads of socially at-risk Medicare patients (safety-net clinicians) performed under Medicare's new mandatory Merit-Based Incentive Payment System (MIPS).
ACM, the Association for Computing Machinery, recently released its eighth annual Study of Non-Doctoral Granting Departments in Computing (NDC study). With the aim of providing a comprehensive look at computing education, the study includes information on enrollments, degree completions, faculty demographics, and faculty salaries. For the first time, this year's ACM NDC study includes enrollment and degree completion data from the National Student Clearinghouse Research Center (NSC).
CLEVELAND--New geologic findings about the makeup of the Earth's mantle are helping scientists better understand long-term climate stability and even how seismic waves move through the planet's layers.
The research by a team including Case Western Reserve University scientists focused on the "deep carbon cycle," part of the overall cycle by which carbon moves through the Earth's various systems.
In simplest terms, the deep carbon cycle involves two steps:
PITTSBURGH, Sept. 10, 2020 - Vocabulary that one uses to describe their emotions is an indicator of mental and physical health and overall well-being, according to an analysis led by a scientist at the University of Pittsburgh School of Medicine and published today in Nature Communications. A larger negative emotion vocabulary--or different ways to describe similar feelings--correlates with more psychological distress and poorer physical health, while a larger positive emotion vocabulary correlates with better well-being and physical health.
