People often resort to using hate speech when searching about terrorism on a community social media platform, a study has found.
Community question answering sites (CQAs) are social media platforms where users ask questions, answer those submitted by others, and have the option to evaluate responses.
Previous studies have mainly looked at terrorism-related data drawn from Facebook and Twitter, this was the first to examine trends on the CQA site, Yahoo! Answers.
The RAF protein could be a therapeutical target to treat the tumor growth in regulated pathways by the p38 protein, according to a new study published in the journal Scientific Reports by a team of experts of the Faculty of Medicine and Health Sciences of the University of Barcelona and the Bellvitge Institute for Biomedical Research (IDIBELL).
The study analyzes the mechanisms that regulate some molecular signaling pathways related to carcinogenesis and tumor progression and opens new perspectives to the fight against human cancer.
All animal cells have an organelle called a centrosome, which is essential to the organization of their cell skeleton. The centrosome plays fundamental roles, especially during cell division, where it allows equal sharing of genetic information between two daughter cells. When the cells stop dividing, the centrioles, cylindrical structures composed of microtubules at the base of the centrosome, migrate to the plasma membrane and allow the formation of primary and mobile cilia, which are used respectively for the transfer of information and the genesis of movement.
Seizure disorders in babies are frightening and heartbreaking. A new basic science breakthrough offers hope for a potential treatment for rare developmental and epileptic encephalopathies resulting from a single genetic mutation. The gene in question, called SCN8A, controls a sodium channel that allows neurons to transmit an electric signal. When this gene is mutated, these channels can become hyperactive, resulting in recurrent seizures. The average age of onset of SCN8A-related encephalopathy is just four months old.
Proactive outreach, including knocking on the doors of individuals who recently overdosed on opioids, can be an effective way to engage more people who have opioid use disorder with long-term care, according to researchers at The University of Texas Health Science Center at Houston (UTHealth).
Scientists from Trinity College Dublin have made an important discovery with implications for those living with a common, debilitating eye disease (age-related macular degeneration, AMD) that can cause blindness.
They have discovered that the molecule TLR2, which recognises chemical patterns associated with infection in the body, also seems to play an important role in the development of retinal degeneration.
A signal originally detected by the Kepler spacecraft has been validated as an exoplanet using the Habitable-zone Planet Finder (HPF), an astronomical spectrograph built by a Penn State team and recently installed on the 10m Hobby-Eberly Telescope at McDonald Observatory in Texas. The HPF provides the highest precision measurements to date of infrared signals from nearby low-mass stars, and astronomers used it to validate the candidate planet by excluding all possibilities of contaminating signals to very high level of probability.
An international team of astronomers used two of the most powerful radio telescopes in the world to create more than three hundred images of planet-forming disks around very young stars in the Orion Clouds. These images reveal new details about the birthplaces of planets and the earliest stages of star formation.
Climate change, with more and more storms and heat waves, also has consequences for our energy supply. An international research team has now developed a new method for calculating how extreme weather affects energy systems.
Climate change is often described in terms of average temperature changes. But it is mainly extreme weather events, like cold snaps, autumn storms and summer heat waves, that have the greatest impact on the economy and society.
Researchers at the University of Toronto Engineering have developed a tiny "heater" - about the size of a pill - that could allow resource-limited regions around the world to test for infectious diseases without the need for specialized training or costly lab equipment.
The technology regulates the temperature of biological samples through different stages of diagnostic testing, which is crucial to the accuracy of test results.
In a new study published today in JAMA Cardiology, a team of researchers led by Rishi Wadhera, MD, MPP, MPhil, an investigator in the Smith Center for Outcomes Research in Cardiology at Beth Israel Deaconess Medical Center (BIDMC), found that hospitals that received awards from the American Heart Association (AHA) and American College of Cardiology (ACC) for the delivery of high-quality care for acute myocardial infarction (AMI) and heart failure (HF) were more likely to be financially penalized under value-based programs than other hospitals.
PITTSBURGH--Computational biologists at Carnegie Mellon University have taken an algorithm used to study social networks, such as Facebook communities, and adapted it to identify how DNA and proteins are interconnected into communities within the cell nucleus.
Using a mixture of oil droplets and hydrogel, medical active agents can be not only precisely dosed, but also continuously administered over periods of up to several days. The active agents inside the droplets are released at a constant rate, decreasing the risk of over- or underdosage.
Actually, Prof. Job Boekhoven was studying the origins of life: Together with his team at the Technical University of Munich (TUM), the chemist wanted to understand how molecules in the primordial ocean had managed to combine and form the precursors of the first living cells.
RIVERSIDE, Calif. -- Researchers at the University of California, Riverside, have completed a cross-sectional human study that compares biomarkers and metal concentrations in the urine of e-cigarette users, nonsmokers, and cigarette smokers.
They found that the biomarkers, which reflect exposure, effect, and potential harm, are both elevated in e-cigarette users compared to the other groups and linked to metal exposure and oxidative DNA damage.
The structure of vegetation and steam distance are important factors to consider in order to protect the biodiversity of forest arthropods, as stated in an article now published in the journal Forest Ecology and Management. The conclusions of the study note the farther we are from a river course, the better conditions for the communities of arthropods in the forests, since they need a cool and wet microclimate.
