Astronomers probing the edges of the Milky Way have in recent years observed some of the most brilliant pyrotechnic displays in the galaxy: superflares.
These events occur when stars, for reasons that scientists still don't understand, eject huge bursts of energy that can be seen from hundreds of light years away. Until recently, researchers assumed that such explosions occurred mostly on stars that, unlike Earth's, were young and active.
Researchers at CU Boulder have discovered hints that humanity's favorite star may have a dual personality, with intriguing discrepancies in its magnetic fields that could hold clues to the sun's own "internal clock."
Infectious proteins called prions cause a group of related, fatal and incurable neurodegenerative disorders, including bovine spongiform encephalopathy or Mad Cow disease and Creutzfeldt-Jakob disease, both of which affect humans.
Baltimore (June 11, 2019) - When prescribed the anticoagulant drug warfarin, many patients are told to limit foods rich in vitamin K, such as green vegetables. The results of a new clinical trial call that advice into question and suggest patients on warfarin actually benefit from increasing their vitamin K intake--as long as they keep their intake levels consistent.
Businesses actively embracing artificial intelligence and striving to bring technological advancements into their operations are reaping dividends not seen by companies who fail to properly adapt and adopt.
While most business and technology leaders are optimistic about the value-creating potential of AI in their enterprise - Enterprise Cognitive Computing (ECC) - the actual rate of adoption is low, and benefits have proved elusive for a majority of organisations.
A genome-wide search in thousands of children in the UK and Netherlands has revealed genetic variants associated with differing levels of protective antibodies produced after routine childhood immunizations. The findings, appearing June 11 in the journal Cell Reports, may inform the development of new vaccine strategies and could lead to personalized vaccination schedules to maximize vaccine effectiveness.
WASHINGTON, D.C., June 11, 2019 -- A new energy-efficient data routing algorithm developed by an international team could keep unmanned aerial vehicle swarms flying -- and helping -- longer, report an international team of researchers this month in the journal Chaos, from AIP Publishing.
There were more than 16.9 million Americans with a history of cancer on January 1, 2019, a number that is projected to reach more than 22.1 million by 2030 based on the growth and aging of the population alone, according to estimates from Cancer Treatment and Survivorship Statistics, 2019. The report is produced every three years by the American Cancer Society in collaboration with the National Cancer Institute to help the public health community better serve this growing population.
Bottom Line: In a new recommendation, the U.S. Preventive Services Task Force (USPSTF) recommends clinicians offer preexposure prophylaxis (PrEP) with effective antiretroviral therapy to people at high risk of acquiring HIV to decrease their risk of infection with the virus that causes AIDS. The USPSTF routinely makes recommendations about the effectiveness of preventive care services. This recommendation statement comes after a review of the evidence on the benefits of PrEP to prevent HIV infection.
Bottom Line: The U.S. Preventive Services Task Force (USPSTF) recommends screening for HIV infection in adolescents and adults ages 15 to 65; in those younger or older at increased risk of infection; and in all pregnant people. The USPSTF routinely makes recommendations about the effectiveness of preventive care services and this statement is an update of its 2013 recommendation. About 15% of people living with HIV are unaware of their infection, and it is estimated that those individuals are responsible for 40% of HIV transmissions in the United States.
WASHINGTON, D.C., June 11, 2019 - Sustainable communities supplied by local renewable energy production are beginning to be established in the U.S. By using energy-efficient buildings and distributing means of energy generation, such as solar panels, throughout buildings in these districts, the communities manage to produce enough energy for their local needs -- achieving a yearly net zero energy (NZE) balance.
A massive 'hit-and-run' collision profoundly impacted the evolutionary history of Vesta, the brightest asteroid visible from Earth. This finding, by a team of researchers from Tokyo Institute of Technology, Japan's National Institute of Polar Research and ETH Zurich, Switzerland, deepens our understanding of protoplanet formation more than 4.5 billion years ago, in the early infancy of the Solar System.
As multinational organizations such as the United Nations strive to improve life for people across the globe through initiatives like the Sustainable Development Goals, there is a tendency to look for indicators that can be used across the board to drive policy aimed at achieving these objectives.
A group of researchers from Japan has discovered a novel enzyme from a soil fungus. In their study published in the Journal of Biological Chemistry, they speculate that this enzyme plays important roles in the soil ecosystem, and then describe its structure and action. Once the usefulness of the main product of this enzyme is better understood in the future, this enzyme could also be exploited for industrial purposes.
A Swansea University study has revealed how as little as an hour a week of outdoor learning has tremendous benefits for children and also boosts teachers' job satisfaction.
Through interviews and focus groups, researchers explored the views and experiences of pupils and educators at three primary schools in south Wales that had adopted an outdoor learning programme, which entailed teaching the curriculum in the natural environment for at least an hour a week.
