ARLINGTON HEIGHTS, Ill (November 13, 2020) - Parents of children with food allergies find their children are often bullied by classmates, as well as parents of other children and teachers. A new study being presented at this year's virtual American College of Allergy, Asthma and Immunology (ACAAI) Annual Scientific Meeting shows that nearly one in five parents of food-allergic kids are the target of bullying by a multitude of sources.
What The Study Did: This randomized trial compares the effects of fluvoxamine, a selective serotonin reuptake inhibitor with immunomodulatory effects, versus placebo on a composite of dyspnea or pneumonia and oxygen desaturation among adult outpatients with polymerase chain reaction-confirmed mild COVID-19 illness.
Authors: Eric J. Lenze, M.D., of the Washington University School of Medicine in St. Louis, is the corresponding author.
Researchers from Kumamoto University (Japan) have developed a system to quickly and easily measure the antioxidant capacity of food. The new electrochemical system uses a gel form Bicontinuous Microemulsion (BME), a mixture of water and oil that do not normally mix, integrated with a sheet-type electrode. This system can easily be used by anyone anywhere and is expected to be used for quality control in the production, manufacturing and sale of food products.
The quest for high throughput intelligent computing paradigms - for big data and artificial intelligence - and the ever-increasing volume of digital information has led to an intensified demand for high-speed and low-power consuming next-generation electronic devices. The "forgotten" world of antiferromagnets (AFM), a class of magnetic materials, offers promise in future electronic device development and complements present-day ferromagnet-based spintronic technologies (Fig. 1).
When you cool down liquid water, it crystallizes into ice. Consider a bucket filled with water, for example. When the water is liquid, the water molecules can be anywhere inside the bucket. In this sense, every point inside the bucket is equivalent. Once the water freezes, however, the water molecules occupy well-defined positions in space. Thus, not every point inside the bucket is equivalent anymore. Physicists refer to this phenomenon as spontaneous symmetry breaking. Here the translation symmetry in space is broken by the formation of the crystal.
Small electronic circuits power our everyday lives, from the tiny cameras in our phones to the microprocessors in our computers. To make those devices even smaller, scientists and engineers are designing circuitry components out of single molecules. Not only could miniaturized circuits offer the benefits of increased device density, speed, and energy efficiency -- for example in flexible electronics or in data storage -- but harnessing the physical properties of specific molecules could lead to devices with unique functionalities.
Europe is to become the first climate-neutral continent by 2050 - this goal of the "Green Deal" was announced by the EU in late 2019. Carbon emissions shall be reduced, while forestation, agriculture, environmentally friendly transport, recycling, and renewable energies shall be pushed. In Nature, scientists of Karlsruhe Institute of Technology (KIT) now show that this "Green Deal" might be a bad deal for the planet, as the EU will outsource environmental damage by high imports of agricultural products. The researchers recommend actions for the deal to push global sustainability.
Oceans are a bellwether for the planet's health, absorbing over 90% of the sun's energy. They demonstrate the extent to which rising temperatures are threatening coral reefs and other vital ecosystems that support biodiversity. In 2016 and 2017, an abrupt rise in surface temperatures in the Pacific Ocean caused mass bleaching on an unprecedented scale. Australia's Great Barrier Reef was especially hard-hit.
LARAMIE, Wyo. - For the first time, state and federal wildlife biologists have come together to map the migrations of ungulates - hooved mammals such as mule deer, elk, pronghorn, moose and bison - across America's West. The maps will help land managers and conservationists pinpoint actions necessary to keep migration routes open and functional to sustain healthy big-game populations.
The prevalence of caesarean section has increased globally in recent decades. While the World Health Organisation suggests that the procedure should be performed in less than 15% of births to prevent morbidity and mortality, the prevalence is higher in most countries. Children born by caesarean section have an increased risk of developing asthma and other immune-mediated diseases compared to children born by vaginal delivery. A link between caesarean section and later disease has been suggested to be mediated through microbial effects.
A glacier that had held an Alaskan slope in place for centuries is melting, releasing the soil beneath in what can be described as a slow-motion landslide, researchers say. But there's also the possibility of a real landslide that could cause a devastating tsunami.
In a study published last week, scientists noted that the slope on Barry Arm fjord on Prince William Sound in southeastern Alaska slid some 120 meters from 2010 to 2017. These are some of the first measurements to quantify how the slope is falling there.
JILA researchers have used a state-of-the-art atomic clock to narrow the search for elusive dark matter, an example of how continual improvements in clocks have value beyond timekeeping.
Liquids aren't as well behaved in space as they are on Earth. Inside a spacecraft, microgravity allows liquids to freely slosh and float about.
In April 2020, as Delaware and states across the country adopted social distancing measures to deal with the public health crisis caused by the coronavirus (COVID-19), University of Delaware professor Cristina Archer recalled having a bunch of people tell her that the skies looked bluer than usual.
A collaborative team of scientists has pinpointed two new potential therapeutic targets for rheumatoid arthritis - a painful inflammatory disease that affects an estimated 350 million people worldwide.
Rheumatoid arthritis (RA) is the most common form of Inflammatory arthritis, affecting 1-2% of the world's population. It is characterised by progressive joint inflammation, damage and disability, which severely impacts a patient's quality of life. There is currently no cure.
