3D printed nanomagnets unveil a world of patterns in the magnetic field
Peer-Reviewed Publication
Researchers from the University of Cambridge have created DNA-like magnetic nanostructures that form strong inter-helix magnetic bonds. These produce topological textures in the magnetic field, opening the door to the next generation of magnetic devices, and patterning magnetic fields on the nanoscale.
Particles in quantum systems have many potential values, making them hard to simulate with a conventional computer. Researchers have proposed a new way to prepare energy states of a simulated quantum system using a quantum computer. Researchers first determine the energy state they are interested in creating. The quantum computer starts the system in a simplified state, then produces different combinations of how the variables evolve over time, then eliminates the energy states that don’t match researchers’ targets.
Middle-aged men are around 50% more likely to die after surgery than middle-aged women, according to new research being presented at Euroanaesthesia, the annual meeting of the European Society of Anaesthesiology and Intensive Care (ESAIC), held online this year. The study of more than 100,000 non-cardiac patients at a leading German hospital found that mortality rates are higher in men in their 40s and 50s, as well as those in their 60s and 70s.
A computer analysis of hundreds of thousands of secure email messages between doctors and patients found that most doctors use language that is too complex for their patients to understand. The study also uncovered strategies some doctors use to overcome communication barriers.
Argonne scientist Laura Gagliardi has been elected to the Italian National Academy of Sciences.
What The Study Did: This study of 1.1 million commercially insured patients with type 2 diabetes investigated whether there are inequities in use of a class of diabetes medications known as glucagon-like peptide-1 receptor agonists (GLP-1 RA) based on race, ethnicity, sex and socioeconomic status.
The iconic tusked whale of the Arctic has a new enemy – noise. A unique study from the University of Copenhagen and the Greenland Institute of Natural Resources shows that narwhals are highly affected by noise from ships and seismic airgun pulses – even at 20-30 kilometers away. As ice melts, noise levels in the Arctic are rising, worrying scientists about the future of narwhals.
