HSE University researchers have confirmed that the level of phonological processing skills in children can impact their ability to master reading. Complex phonological tests are best suited to detect phonological impairment. The study was published on September 6, 2020, in the Journal of Research in Reading.
Greenwood, SC (September 17, 2020) - Greenwood Genetic Center (GGC) researchers, in collaboration with scientists from Belgium, Spain, and Italy, have confirmed that variants in LMNB1 cause syndromic microcephaly with variable short stature, intellectual disability, and other neurological symptoms. The findings are reported in the October issue of the American Journal of Human Genetics.
High-speed cameras can take pictures in quick succession. This makes them useful for visualizing ultrafast dynamic phenomena, such as femtosecond laser ablation for precise machining and manufacturing processes, fast ignition for nuclear fusion energy systems, shock-wave interactions in living cells, and certain chemical reactions.
About a year ago, a conversation during a faculty meeting piqued Marcus Crede's interest. A senior faculty member in Iowa State University's Department of Psychology said that he believed frequent quizzes help students better grasp classroom material. Crede, an associate professor of psychology, was skeptical that something as simple as a quiz could positively impact students' academic performance. He decided to dig deeper and conduct a meta-analytic study of existing research to see if there was any merit to the claim. What he discovered truly surprised him.
Fruit flies have the uncanny ability to wake up from a months-long hibernation right when their food of choice—say, the fruit from apple or Hawthorn trees—is at its peak. They’re active for a couple of weeks, eating and mating, before going dormant for the rest of the year. How this synchronization and remarkable timing happens has long been a mystery. In a world where global climate change is shifting the growing seasons, somehow the fruit flies keep up.
An Australian collaboration has reviewed the fundamental theories underpinning the quantum anomalous Hall effect (QAHE).
QAHE is one of the most fascinating and important recent discoveries in condensed-matter physics.
It is key to the function of emerging 'quantum' materials, which offer potential for ultra-low energy electronics.
QAHE causes the flow of zero-resistance electrical current along the edges of a material.
QAHE IN TOPOLOGICAL MATERIALS: KEY TO LOW-ENERGY ELECTRONICS
A new study by researchers at the University of Illinois Chicago and the University of Pittsburgh suggests that a significant proportion of older patients receiving opioids at dental visits also use psychotropic medications -- a potentially harmful combination. Their findings are published in the journal Pharmacotherapy.
A new study led by Dr. Matthew Rossheim at the George Mason University College of Health and Human Services provides important findings on how labeling of secondhand emissions from e-cigarettes can help more effectively communicate the harm from e-cigarettes and build support for tobacco-free campus policies. In the study Aerosol, vapor, or chemicals?
EAST LANSING, Mich. - When people say that they want to change things about their personalities, they might not know about the inadvertent consequences these changes could bring. In fact, changes in personality may also lead to changes in political ideologies, say researchers from Michigan State University and the University of Granada, who led the study.
A team of researchers from North Carolina State University has demonstrated a way to use low-energy, visible light to produce polymer gel objects from pure monomer solutions. The work not only poses a potential solution to current challenges in producing these materials, it also sheds further light on the ways in which low energy photons can combine to produce high energy excited states.
Ling Gao and colleagues have developed a strategy that uses exosomes - tiny membrane-bound sacs secreted by cells - to mimic the heart-regenerating effects of cardiac cell transplants, while potentially avoiding risks associated with whole-cell transplants. Their approach, which accelerated recovery from heart attack in pigs, could address issues with safety and effectiveness that have prevented whole-cell heart therapies from reaching clinical adoption.
Leesburg, VA, September 16, 2020--According to ARRS' American Journal of Roentgenology (AJR), ultrasound-guided carpal tunnel release (UGCTR) quickly improves hand function and reduces hand discomfort, making UGCTR a safe, effective, and less invasive alternative to traditional open or endoscopic surgery.
A research team from Caltech and the UCLA Samueli School of Engineering has demonstrated a promising way to efficiently convert carbon dioxide into ethylene -- an important chemical used to produce plastics, solvents, cosmetics and other important products globally.
For many people who are struggling to conceive, in-vitro fertilization (IVF) can offer a life-changing solution. But the average success rate for IVF is only about 30 percent. Investigators from Brigham and Women's Hospital and Massachusetts General Hospital are developing an artificial intelligence system with the goal of improving IVF success by helping embryologists objectively select embryos most likely to result in a healthy birth.
Strata completeness refers to "the fraction of time intervals of some specified length (t) that have been preserved". Since the 1780s, it has been widely accepted that most stratigraphic sections are riddled with gaps and are discontinuous over a range of temporal scales.
