Researchers at Pohang University of Science and Technology (POSTECH) and Seoul National University in South Korea have demonstrated a new way to enhance the energy efficiency of a non-volatile magnetic memory device called SOT-MRAM. Published in Advanced Materials, this finding opens up a new window of exciting opportunities for future energy-efficient magnetic memories based on spintronics.
Approximately 170,000 people die every year in Europe from the direct consequences of advanced chronic liver disease (cirrhosis). In Austria, cirrhosis of the liver is usually due to a fatty liver resulting from excessive alcohol consumption or overeating and/or poor diet and - thanks to effective antiviral therapies - less common due to viral hepatitis.
Chronic liver damage leads to scarring (fibrosis) of the liver tissue, which can ultimately lead to increased blood pressure in the vascular system of the gastrointestinal tract (i.e. portal hypertension).
Researchers at Hokkaido University and Amoeba Energy in Japan have, inspired by the efficient foraging behavior of a single-celled amoeba, developed an analog computer for finding a reliable and swift solution to the traveling salesman problem -- a representative combinatorial optimization problem.
Robotic animals could be the 'pawfect' replacement for our real-life furry friends, a new study published today by the University of Portsmouth has found.
Animals, especially dogs, can have therapeutic benefits for children and young people. A new paper, published in The International Journal of Social Robotics, has found that the robotic animal, 'MiRo-E', can be just as effective and may even be a better alternative.
Computer scientists have developed an entirely new way of interacting with video content that adapts to, and is controlled by, your body movement.
Fitness videos and other instructional content that aims to teach viewers new martial arts skills, exercises or yoga positions have been popular since VHS in the 80s and are abundant on Internet platforms like YouTube.
New research suggests testing people's memory over four weeks could identify who is at higher risk of developing Alzheimer's disease before it has developed. Importantly, the trial found testing people's ability to retain memories for longer time periods could predict this more accurately than classic memory tests, which test memory over half an hour.
Thanks to the remarkable progress that has been made in miniaturization over the last decade, wearable electronic devices that were considered far-fetched in the 2000's are within reach. Prime examples of such technology are smart glasses and similar head-mounted displays, which leverage recent advances in virtual and augmented reality to create an immersive experience or provide hands-free utilities.
Because of land use and climate change, lakes and reservoirs globally are seeing large decreases in oxygen concentrations in their bottom waters. It is well-documented that low oxygen levels have detrimental effects on fish and water quality, but little is known about how these conditions will affect the concentration of carbon dioxide and methane in freshwaters.
Alexandria, Va., USA -- The COVID-19 pandemic has revealed the need for consensus on the definition of essential oral healthcare. The article "Pandemic considerations on essential oral healthcare" provides a layered model of essential oral healthcare, integrating urgent and basic oral healthcare, as well as advanced and specialist oral healthcare.
Lisle, Ill. (Dec. 10) -- An estimated 31% of the world's oak species are threatened with extinction according to data compiled in a new report by The Morton Arboretum and the International Union for Conservation of Nature (IUCN) Global Tree Specialist Group, The Red List of Oaks 2020.
Police who investigate online crimes against children, and protect wider society from seeing images of violence against young people, are themselves at risk of moral injury and other psychological harms.
When plants absorb this gas to grow, they remove it from the atmosphere and it is sequestered in their branches, trunk or roots. An article published today in Science shows that this fertilizing effect of CO2 is decreasing worldwide, according to the text co-directed by Professor Josep Peñuelas of the CSIC at CREAF and Professor Yongguan Zhang of the University of Nanjin, with the participation of CREAF researchers Jordi Sardans and Marcos Fernández.
Around a quarter of the ground in the northern hemisphere is permanently frozen. These areas are estimated to contain about twice as much carbon as the world's current atmosphere. New research says that these permafrost soils are not only increasingly thawing out as the Earth becomes warmer, but also releasing that carbon, which accelerates the thawing.
BUFFALO, N.Y. -- University at Buffalo researchers are reporting a new, two-dimensional transistor made of graphene and the compound molybdenum disulfide that could help usher in a new era of computing.
As described in a paper accepted at the 2020 IEEE International Electron Devices Meeting, which is taking place virtually next week, the transistor requires half the voltage of current semiconductors. It also has a current density greater than similar transistors under development.
Fast facts:
Bioluminescence is an energy-conserving process of natural production of cold light that many lower organisms use for communication, capturing prey, or mating.
This wondrous phenomenon has long fascinated scientists and the public, but many details of the chemical reactions used to produce light remain unclear. For example, it remains uncertain why various beetle species can emit different colors of light, despite using very similar light-producing enzymes.
