In 2016, a collaborative group of research and education specialists received funding from the National Science Foundation for the project 'Building a Comprehensive Evolutionary History of Flagellate Plants' -- also known as 'Genealogy of Flagellate Plants' (GoFlag). Members of the team have the ambitious goal of reconstructing the 470-million-year history of one of the most diverse groups of land plants on the planet.
An international team of researchers, affiliated with UNIST has unveiled a novel technology that could improve the learning ability of artificial neural networks (ANNs).
Professor Hongsik Jeong and his research team in the Department of Materials Science and Engineering at UNIST, in collaboration with researchers from Tsinghua University in China, proposed a new learning method to improve the learning ability of ANN chips by challenging its instability.
A chromatin-regulating enzyme has been shown by in-depth interdisciplinary investigations to be a key driver of a common type of lung cancer. Drugs that target the enzyme could improve treatment and survival rates for this particular cancer.
Basic, acidic, basic again: for pathogenic bacteria such as Salmonella, the human digestive tract is a sea change. So how do the bacteria manage to react to these changes? A team of researchers from the Max Planck Institute for Terrestrial Microbiology in Marburg led by Andreas Diepold has now provided a possible explanation: pathogenic bacteria can change components of their injection apparatus on the fly - like changing the tires on a moving car - to enable a rapid response.
Despite pandemic-driven restrictions on movement, there were over 12,000 accidents in Madrid in 2020, leading to 31 fatalities. In Barcelona, there were more than 5,700 collisions, causing 14 deaths. Pedestrian and vehicle safety is a priority, which is why a research project at the Universitat Oberta de Catalunya (UOC) is harnessing artificial intelligence (AI) to make decisions that will make cities safer. The researchers have looked into the correlation between the complexity of certain urban areas and the likelihood of an accident occurring there.
In the first all-sky survey by the eROSITA X-ray telescope onboard SRG, astronomers at the Max Planck Institute for Extraterrestrial Physics have identified a previously unknown supernova remnant, dubbed "Hoinga". The finding was confirmed in archival radio data and marks the first discovery of a joint Australian-eROSITA partnership established to explore our Galaxy using multiple wavelengths, from low-frequency radio waves to energetic X-rays.
A large study of people in 28 countries found men aged 50 and over had a 60% greater risk of death than women, partly explained by heavier rates of smoking and heart disease in men, although the gap varied across countries, according to new research in CMAJ (Canadian Medical Association Journal) .
ANN ARBOR, Mich. - For teens, pandemic restrictions may have meant months of virtual school, less time with friends and canceling activities like sports, band concerts and prom.
And for young people who rely heavily on social connections for emotional support, these adjustments may have taken a heavy toll on mental health, a new national poll suggests.
(COLUMBUS, Ohio) - High-powered magnets are small, shiny magnets made from powerful rare earth metals. Since they started showing up in children's toys in the early 2000s and then later in desk sets in 2009, high-powered magnets have caused thousands of injuries and are considered to be among the most dangerous ingestion hazards in children.
Around three times as many males are diagnosed with autism than females. This suggests that biological sex factors may play a role in the development and presentation of autism.
Studies on the neurobiology (brain biology) of males and females with autism have begun to examine brain networks but results have been mixed. This is largely due to the limited availability of data from autistic females.
Intake of a high-fat diet leads to an increased risk for obesity, type 2 diabetes, cardiovascular diseases and fatty liver. A study in mice from Karolinska Institutet in Sweden shows that it is possible to eliminate the deleterious effects of a high-fat diet by lowering the levels of apolipoprotein CIII (apoCIII), a key regulator of lipid metabolism. The study is published in the journal Science Advances.
New review explores effective sampling techniques for collecting airborne viruses and ultrafine part
As the world continues to grapple with the COVID-19 pandemic, an international team of researchers have published a review of the best techniques to collect airborne aerosols containing viruses.
In the review, which was published by the Science of the Total Environment journal, a team led by the University of Surrey concluded that the most effective way to collect and detect airborne pathogens, particularly viruses, was to use cyclone sampling techniques.
The Cabeza de los Gatos waste rock pile, left from mining activities in the town of Tharsis (Huelva), underwent a rehabilitation process consisting of remodelling the slope of the pile, applying liming materials and then a layer of soil. Finally, trees and shrubs typical of the area were planted and a hydroseeding with a mixture of shrub and herbaceous seeds was applied.
In asthma, the airways become hyperresponsive. Researchers from Uppsala University have found a new mechanism that contributes to, and explains, airway hyperresponsiveness. The results are published in the scientific journal Allergy.
Some 10 per cent of Sweden's population suffer from asthma. In asthmatics, the airways are hyperresponsive (overreactive) to various types of stimuli, such as cold air, physical exertion and chemicals. The airways become constricted, making breathing difficult.
Scientists have long theorized that supermassive black holes can wander through space--but catching them in the act has proven difficult.
Now, researchers at the Center for Astrophysics | Harvard & Smithsonian have identified the clearest case to date of a supermassive black hole in motion. Their results are published today in the Astrophysical Journal.
