Astrophysicists at MIPT's Laboratory of Fundamental and Applied Research of Relativistic Objects of the Universe have developed a model for testing a hypothesis about supermassive black holes that lie at the centers of galaxies. The new model enables scientists to predict how much rotational energy a black hole loses when it emits beams of ionized matter known as astrophysical jets. The energy loss is estimated based on measurements of a jet's magnetic field. The paper was published in the journal Frontiers in Astronomy and Space Sciences.
Web-based learning tools can help deepen science knowledge among all middle school students, and ease the science literacy gap for underachieving students, according to a three-year study published today in the International Journal of Science Education.
Researchers introduced four interactive online science units, which students and teachers accessed with computers or tablets, into 13 middle school in two US states.
Feb. 6, 2018--Thousands of lives would be saved each year, and many more serious illnesses avoided, if U.S. counties met standards set by the American Thoracic Society for the two most important air pollutants, according to a new report by the ATS and the Marron Institute of Urban Management at New York University.
The ATS's standards for ozone (O3) and fine particulate matter (PM2.5) are more protective than those adopted by the U.S. Environmental Protection Agency. If the ATS's standards were met, each year in the U.S. approximately:
6,270 lives would be saved,
PHILADELPHIA (February 5, 2018) - Pressure-related skin injuries, a nurse-sensitive quality indicator in hospitals, are associated with increased morbidity and higher costs of care. There's been much attention focused on hospital-acquired pressure injuries (HAPI) in the adult population. However, while preventable, immobility-related and medical device-related pressure injuries (MDPI) also occur in hospitalized infants and children.
In a study to be published online February 2 in Nature Communications, scientists from the Icahn School of Medicine at Mount Sinai describe an extensive analysis of novel grape-derived compounds, dihydrocaffeic acid (DHCA) and malvidin-3'-O-glucoside (Mal-gluc),which might be developed as therapeutic agents for the treatment of depression. The study results indicate that these natural compounds may attenuate depression by targeting newly discovered underlying mechanisms of the disease.
A research team from the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) has found the first evidence that a shaking motion in the structure of an atomically thin (2-D) material possesses a naturally occurring circular rotation.
This rotation could become the building block for a new form of information technology, and for the design of molecular-scale rotors to drive microscopic motors and machines.
RESEARCH TRIANGLE PARK, NC-- A recent nationally-representative U.S. Department of Education study found that 28 percent of fall 2009 ninth-graders had not yet enrolled in a trade school or college by February 2016-- roughly six-and-a-half years later.
Sixty percent of these high school graduates worried about having enough money for regular expenses according to the report written by RTI International. More than 25 percent also reported receiving regular help from their parents to cover rent and other housing expenses.
Researchers have developed a new tool which could benefit organisations and their staff by assessing employees' beliefs about how they manage challenging and stressful situations at work.
Self-efficacy - the belief in one's capabilities to achieve a goal or an outcome - is a key variable for understanding how people manage themselves and their behaviour at work, given its influence on motivation, well-being, and personal achievement and fulfilment.
WASHINGTON -- While the U.S. Department of Veterans Affairs (VA) provides mental health care of comparable or superior quality to care provided in private and non-VA public sectors, accessibility and quality of services vary across the VA health system, leaving a substantial unmet need for mental health services among veterans of the recent wars in Afghanistan and Iraq, says a new congressionally mandated report from the National Academies of Sciences, Engineering, and Medicine.
January 30, 2018 - The risks of penile reconstruction surgery (phalloplasty) appear higher in female-to-male transgender (transmale) patients undergoing gender confirmation surgery, compared to native male (cismale) patients undergoing phalloplasty for other reasons, reports a study in the February issue of Plastic and Reconstructive Surgery®, the offici
