Researchers at the Niels Bohr Institute, University of Copenhagen and DTU Space in Lyngby have determined the emission of extremely energetic light particles during the death of a very heavy star for the first time. The discovery was made in collaboration with a large, international team of scientists. The light particles were measured with the telescope MAGIC, situated on the Canary Islands. The researchers at the Niels Bohr Institute subsequently measured the particles with the neighboring Nordic Optical Telescope.
Dutch artist M.C. Escher's most famous drawing, "Circle Limit IV (Heaven and Hell)", shows angels and demons in a tessellation that fills a circle without empty spaces. This masterful woodcut inspired an international partnership of researchers including Politecnico di Milano Physics Department to author the cover-story article published in Physical Review Letters (*).
This free and unconventional work-of-art has provided a valuable assistance to science.
A high percentage of schools buildings in Andalusia does not have the necessary mechanical ventilation equipment or filtration systems in place, so air has to be renewed by means of infiltrations or opening the windows. A recent University of Seville study has analysed the air tightness of classrooms in Andalusia and the evolution of CO2 levels during the school day, via in situ monitoring, which serves as an indicator to determine air quality.
Redox flow batteries are an emerging technology for electrochemical energy storage that could help enhance the use of power produced by renewable energy resources. These power resources are inherently irregular in their supply, which doesn't typically align with demand on the power grid. In principle, redox flow batteries can be designed to have an energy-storage capacity that is independent of its power rating.
From a modest 150 words to the length of a children's book - the number of words used by politicians in their election manifestos has grown substantially in the past century, new research shows.
Far from becoming irrelevant because few voters now manage to plough through the mammoth documents, manifestos now have a quasi-constitutional significance, according to historians.
The local release of antitumoral drugs through bacterial proteins in the treatment of breast cancer can mark a before and after in precision medicine. In this sense, researchers at the CIBER of Bioengineering, Biomaterials and Nanomedicine (CIBER-BBN) of the Universitat Autònoma de Barcelona (UAB), the Vall d'Hebron Research Institute (VHIR) and the Spanish National Research Council (CSIC) have created Escherichia coli cell structures to produce non-toxic bacterial amyloids.
The quest to develop the understanding for time crystalline behaviour in quantum systems has taken a new, exciting twist.
Physics experts from the Universities of Exeter, Iceland, and ITMO University in St. Petersburg, have revealed that the existence of genuine time crystals for closed quantum systems is possible.
A tide of public momentum is swelling against the crisis of petroleum-based plastics, which are sitting in our landfills, floating in our oceans, and showing up in our air and even our food.
Meanwhile, in a Colorado State University chemistry laboratory, polymer scientists are toiling toward what they think is a viable solution. Every day, they are working on new chemistry for sustainable materials that could compete with, and eventually even replace, the hard-to-recycle, non-degradable commodity plastics that have overwhelmed our environment for decades.
ATLANTA--The number of U.S. adults who perceive e-cigarettes to be at as harmful as, or more harmful than, cigarettes has increased between 2017 and 2018, even prior to the national outbreak of vaping-related lung disease and deaths, a study by tobacco researchers from Georgia State University's School of Public Health has found.
The findings, published in JAMA Network Open, augment earlier work by the researchers that found an increase in perceived harm of e-cigarettes relative to cigarettes between 2012 and 2017.
NASA's Aqua satellite captured an image of Tropical Depression Kalmaegi in the South China Sea as it was dissipating.
On Nov. 20, Kalmaegi had crossed over Luzon, the northernmost island of the Philippines. The storm then moved into the South China Sea where it encountered stronger wind shear, winds that can tear a storm apart. Kalmaegi is known locally in the Philippines as Tropical Cyclone Ramon.
With seemingly endless emails, phone calls and meetings, it's no secret that working in an office environment can be quite stressful. Understanding how stress manifests by exposing the effects of distractions can help unlock an office workers' full potential, according to new data collected by researchers from three university laboratories.
Adjusting the water flow rate in a river can prevent invasive species from moving upstream and expanding their range. An applied mathematician at UT has developed a partial differential equation model to find the desired flow rate to reduce invasive populations.
The model is detailed in a new paper by Suzanne Lenhart, Chancellor's Professor and James R. Cox Professor of Mathematics, published in Mathematics.
A review of the literature led by researchers from the University of Florida attempts to provide clarification and analysis on various aspects of what a controlled environment system entails and the extent to which differing food production approaches can be applied to the many current and hopeful endeavors of Urban Agriculture.
NASA's Terra satellite captured a visible image of Tropical Storm Sebastien that showed wind shear had pushed the bulk of its clouds and showers to the southeast of the center.
Most mammals walk at slow speeds and run or trot at intermediate speeds because these movement strategies are energetically optimal, according to a study published in PLOS Computational Biology by Delyle Polet and John Bertram of the University of Calgary in Alberta, Canada.
