Loneliness is a risk factor associated with adolescents being drawn into compulsive internet use. The risk of compulsive use has grown in the coronavirus pandemic: loneliness has become increasingly prevalent among adolescents, who spend longer and longer periods of time online. A study investigating detrimental internet use by adolescents involved a total of 1,750 Finnish … [Read more...] about Lonely adolescents are susceptible to internet addiction

A team of quantum theorists seeking to cure a basic problem with quantum annealing computers -- they have to run at a relatively slow pace to operate properly -- found something intriguing instead. While probing how quantum annealers perform when operated faster than desired, the team unexpectedly discovered a new effect that may account for the imbalanced distribution of … [Read more...] about Lack of symmetry in qubits can’t fix errors in quantum computing, might explain matter/antimatter

Cornell University scientists have identified a new contender when it comes to quantum materials for computing and low-temperature electronics. Using nitride-based materials, the researchers created a material structure that simultaneously exhibits superconductivity -- in which electrical resistance vanishes completely -- and the quantum Hall effect, which produces resistance … [Read more...] about ‘Beautiful marriage’ of quantum enemies

You might not like mosquitoes, but they like you, says Utah State University biologist Norah Saarman. And where you lead, they will follow. In addition to annoying bites and buzzing, some mosquitoes carry harmful diseases. Aedes aegypti, the so-called Yellow Fever mosquito and the subject of a recent study by Saarman and colleagues, is the primary vector for transmission of … [Read more...] about Scientists use machine-learning approach to track disease-carrying mosquitoes

One of the most performed medical diagnostic tests to ascertain the health of patients is a complete blood count, which typically includes an estimate of the hemoglobin concentration. The hemoglobin level in the blood is an important biochemical parameter that can indicate a host of medical conditions including anemia, polycythemia, and pulmonary fibrosis. In AIP Advances, by … [Read more...] about Measuring hemoglobin levels with AI microscope, microfluidic chips: A chip-based, microfluidic, AI-powered diagnostic platform could make medical diagnostics more affordable, accessible.

Critics claim environmental regulations hurt productivity and profits, but the reality is more nuanced, according to an analysis of environmental policies in China by a pair of Cornell economists. The analysis found that, contrary to conventional wisdom, market-based or incentive-based policies may actually benefit regulated firms in the traditional and "green" energy sectors, … [Read more...] about Environmental policies not always bad for business, study finds

To become climate neutral by 2050, the European Union launched two ambitious programmes: "Green Deal" and "DigitalStrategy." As a key component of their successful implementation, climate scientists and computer scientists launched the "Destination Earth" initiative, which will start in mid-2021 and is expected to run for up to ten years. During this period, a highly accurate … [Read more...] about Scientists begin building highly accurate digital twin of our planet

Engineers have developed a technique that allows them to precisely place microscopic devices formed from folded DNA molecules in not only a specific location but also in a specific orientation. As a proof-of-concept, they arranged more than 3,000 glowing moon-shaped nanoscale molecular devices into a flower-shaped instrument for indicating the polarization of light. Each of 12 … [Read more...] about Engineers place molecule-scale devices in precise orientation: Proof-of-concept project paves the way for the integration of molecules with computer chips.

Even in the world of the smallest particles with their own special rules, things cannot proceed infinitely fast. Physicists at the University of Bonn have now shown what the speed limit is for complex quantum operations. The study also involved scientists from MIT, the universities of Hamburg, Cologne and Padua, and the Jülich Research Center. The results are important for the … [Read more...] about A speed limit also applies in the quantum world: Study by the University of Bonn determines minimum time for complex quantum operations

Researchers at the Stowers Institute for Medical Research, in collaboration with colleagues at Stanford University and Technical University of Munich have developed advanced explainable artificial intelligence (AI) in a technical tour de force to decipher regulatory instructions encoded in DNA. In a report published online February 18, 2021, in Nature Genetics, the team found … [Read more...] about Explainable AI for decoding genome biology: Opening the black box to uncover the rules of the genome’s regulatory code
