Now more than ever, people who want to learn a new language turn to their mobile devices for help as language learning applications have become increasingly available. While these apps allow users to study a new language from anywhere at any time, how effective are they?
That is a question Shawn Loewen, professor in the Department of Linguistics and Germanic, Slavic, Asian and African Languages at Michigan State University, is trying to answer.
A ten-year study shows that Asian black bears' diets vary greatly depending on sex, stage of life, and resource availability, providing important information on foraging strategy according to age-sex classes. Researchers in Japan published their findings on April 15 in Mammal Study.
Magnesium is a promising material for use in structural materials because they are lightweight, have high-specific strength, and high-specific stiffness. However, its limited formability at room temperature keeps its potential use limited.
Two decades of research among female athletes over the age of 13 years shows that a lack of nutrition knowledge about what they need to eat to stay healthy and compete may contribute to poor performance, low energy and nutrient intake, and potential health risks, according to a Rutgers Robert Wood Johnson Medical School study.
Toronto, Ontario--Harmful flame retardants may be lurking on your hands and cell phone, according to a peer-reviewed study published today in Environmental Science & Technology Letters.
The researchers found that halogenated flame retardants added to plastic TV cases can move from the TV to indoor air and dust, to hands, and then to cell phones and other hand-held electronic devices. Once on your cell phone, that surface provides an ongoing source of exposure to these chemicals each time you touch your cell phone.
Dating archaeological objects precisely is difficult, even when using techniques such as radiocarbon dating. Using a recently developed method, based on the presence of sudden spikes in carbon-14 concentration, scientists at the University of Groningen, together with Russian colleagues, have pinned the date for the construction of an eighth-century complex in southern Siberia to a specific year. This allows archaeologists to finally understand the purpose for building the complex - and why it was never used.
Irvine, Calif., June 8, 2020 -- Oncology pharmacy practitioners around the globe are fighting to provide cancer patients high quality cancer care with increasingly limited and sometimes restricted personal protective equipment supply as well as impaired access to essential anticancer medication, according to University of California, Irvine-led study.
NEWPORT NEWS, VA - It's not often in nuclear physics that you can clearly get both sides of the story, but a recent experiment allowed researchers to do just that. They compared very similar nuclei to each other to get a clearer view of how the components of nuclei are arranged and found that there's still more to learn about the heart of matter. The research, carried out at the Department of Energy's Thomas Jefferson National Accelerator Facility, was recently published as an editors' suggested read in Physical Review Letters.
PROVIDENCE, R.I. [Brown University] -- A team of Brown University physicists has developed a new type of compact, ultra-sensitive magnetometer. The new device could be useful in a variety of applications involving weak magnetic fields, the researchers say.
HOUSTON - (June 8, 2020) - Rice University scientists have developed an easy and affordable tool to count and characterize nanoparticles.
The Rice labs of chemists Christy Landes and Stephan Link created an open-source program called SEMseg to acquire data about nanoparticles, objects smaller than 100 nanometers, from scanning electron microscope (SEM) images that are otherwise difficult if not impossible to analyze.
NEW YORK, NY (June 8, 2020) --- Hospitalized COVID-19 patients at a New York City medical facility had higher rates of kidney complications than other COVID-19 patient groups in different areas of the U.S. and other countries, according to a new study from researchers at Columbia University Irving Medical Center and NewYork-Presbyterian.
The study, using data from electronic health records and published recently in the British Medical Journal, also found the need for mechanical ventilation was greatest at two different points after symptom onset.
Philadelphia, June 8, 2020--Cancer researchers at Children's Hospital of Philadelphia (CHOP) have harnessed tools used for the development of cancer immunotherapies and adapted them to identify regions of the SARS-CoV-2 virus to target with a vaccine, employing the same approach used to elicit an immune response against cancer cells to stimulate an immune response against the virus. Using this strategy, the researchers believe a resulting vaccine would provide protection across the human population and drive a long-term immune response.
ANCA-associated vasculitis (AAV) is a systemic disease involving the formation of special autoantibodies (so-called anti-neutrophil cytoplasmic antibodies/ANCA) and vascular inflammation. There are several diseases associated with involvement of the kidneys, lungs, upper respiratory tract, heart, skin and the nervous system; potentially life-threatening courses of disease are also possible.
Systemic lupus erythematosus (SLE) is a chronic, inflammatory, autoimmune disease, in which damage is caused to multiple organs and tissues by the formation and deposition of immune complexes (antigen-antibody complexes). The kidneys are also affected in about half of the patients when immune complexes accumulate in the glomeruli, resulting in a glomerulonephritis called lupus nephritis (LN). The severity of LN varies considerably, ranging from unnoticed, to acute and/or chronic terminal kidney failure despite intensive therapy.
The Paris Agreement lays out national quotas on CO2 emissions but not removal, and that must be urgently addressed, say the authors of a new study.
The Paris Agreement aims to keep global temperature rise this century well below 2°C above pre-industrial levels and to pursue efforts to limit it to 1.5°C. Reaching these targets will require mitigation - lowering the carbon dioxide (CO2) emitted through changes such as increased use of renewable energy sources, and removal of CO2 from the atmosphere through measures such as reforestation and carbon capture and storage.
