Scientists in Korea have found a new way to control the alignment state of magnetic atoms in an antiferromagnetic material, showing promise for the development of tiny sensors and memory devices. Researchers at the Daegu Gyeongbuk Institute of Science and Technology (DGIST) describe their new approach featuring a controllable exchange bias effect, which enables the asymmetric magnetic actions of devices comprised of complex combination structure of different types of magnetic materials, in the journal Acta Materialia.

In an international cooperation with partners from industry and research, physicists from the University of Vienna, together with Thorlabs, the National Institute of Standards and Technology (NIST), and the University of Kansas, have now succeeded for the first time in demonstrating high-performance laser mirrors in the sensing-relevant mid-infrared wavelength range that absorb less than ten out of a million photons.

Collaboration between two NCCR MARVEL labs has identified a new type of defect as the most common source of disorder in on-surface synthesized graphene nanoribbons (GNRs). The researchers identified the atomic structure of these "bite" defects and investigated their effect on quantum electronic transport in two different types of GNR. They also established guidelines for minimizing the detrimental impact of these defects and proposed defective zigzag-edged nanoribbons as suitable platforms for certain applications in spintronics.

China's Large High Altitude Air Shower Observatory (LHAASO)--one of the country's key national science and technology infrastructure facilities--has found a dozen ultra-high-energy (UHE) cosmic accelerators within the Milky Way. It has also detected photons with energies exceeding 1 peta-electron-volt (quadrillion electron-volts or PeV), including one at 1.4 PeV. The latter is the highest energy photon ever observed.

Urban megaprojects tend to be the antithesis of good urban planning. They have a negative impact on local water systems, deprive local communities of water-related human rights, and their funders and sponsors have little accountability for their impact.

Fossils of land animals from South America have been found in the Antilles, but how did these animals get there? According to scientists from the CNRS, l'Université des Antilles, l'Université de Montpellier and d'Université Côte d'Azur, land emerged in this region and then disappeared beneath the waves for millions of years, explaining how some species were able to migrate to the Antilles. This study will be published in June 2021 issue in Earth-Science Reviews.

The research team, led by Academician GUO Guangcan from University of Science and Technology of China (USTC) of the Chinese Academy of Sciences, collaborating with LI Bo from Shangrao Normal University and CHEN Jingling from Nankai University, achieved the masking of optical quantum information. The researchers concealed quantum information into non-local quantum entangled states. The study was published in the journal Physical Review Letters.

Fields of opium poppies once bloomed where the Zurich Opera House underground garage now stands. Through a new analysis of archaeological seeds, researchers at the University of Basel have been able to bolster the hypothesis that prehistoric farmers throughout the Alps participated in domesticating the opium poppy.

Researchers have identified specific influenza targets that could be used to better protect Indigenous people from experiencing severe influenza disease through a universal, T cell-based vaccine.In a collaboration with Monash Biomedicine Discovery Institute, Menzies School of Health Research and CQUniversity, Peter Doherty Institute for Infection and Immunity (Doherty Institute) researchers took a deep-dive look into how the immune system can protect Aboriginal and Torres Strait Islander people from severe influenza disease.

An international team of scientists have developed an experimental direct-acting antiviral therapy to treat COVID-19. Traditional antivirals reduce symptoms and help people recover earlier. This next-generation antiviral approach used gene-silencing RNA technology called siRNA (small-interfering RNA) to attack the virus' genome directly, which stops the virus from replicating, as well as lipid nanoparticles designed at Griffith University and City of Hope to deliver the siRNA to the lungs, the critical site of infection.

A rigorous meta-analysis of randomized clinical trials (RCTs) that compared the effects of medical therapies alone with medical therapies plus revascularization in patients with stable ischemic heart disease (SIHD) was presented at EuroPCR on May 18, 2021.

An artificial intelligence program accurately predicts the risk that lung nodules detected on screening CT will become cancerous, according to a new study.

When it comes sharing recipes on social media, what users post, and what they cook may be two different things according to a recent study led by Hong Xue, PhD at George Mason University. The study, published in the Journal of Medical Internet Research (JMIR), analyzed hundreds of recipes and found users liked and pinned posts that were healthy but more heavily engaged off-line with recipes that were high in fat, sugar, and total calories.

The first-ever discovery of an extraterrestrial radioactive isotope on Earth has scientists rethinking the origins of the elements on our planet.

Vaccines are turning the tide in the pandemic, but the risk of infection is still present. Instant at-home tests would help us return to normal, but current options aren't very accurate. A new discovery could help get reliable tests on the market.

Scientists from Hokkaido University have developed a rapid, efficient protocol for cross-coupling reactions, vastly expanding the pool of chemicals that can be used for the synthesis of useful organic compounds.

Scientists have confirmed the species and origin of a colony of wild African vervet monkeys that landed in Dania Beach more than 70 years ago. They escaped from the Dania Chimpanzee Farm in 1948 and settled in a thick mangrove forest near the Fort Lauderdale-Hollywood International Airport in South Florida. The facility acted as a zoo and also provided primates imported from Africa as research subjects in the development of the polio vaccine and other medical research.

In sports, it is common practice to apply ice to sore muscles in order to reduce inflammation. However, a Kobe University-led study on mice has revealed that icing severe muscle injuries may actually prolong the healing process. The results indicate that cooling the injury makes it difficult for macrophages to enter the damaged cells in order to repair them.

New King's College London research - funded by the Medical Research Foundation and published today in Translational Psychiatry - reveals how subtle differences in brain connectivity could offer a sign of risk for postpartum psychosis in women.

A research group led by Specially appointed professor, Dr. Tatsuo Suzuki of Shinshu University's School of Medicine developed a new purification protocol for Postsynaptic density (PSD) lattice, a core structure of the PSD of excitatory synapses in the central nervous system. The components of the PSD lattice were identified by comprehensive shotgun mass spectrometry, and categorized as either minimum essential component (MEC) or non-MEC proteins. Tubulin was found to be a major component of ...
