Phys.org / A little bit more than magic: The secret to quantum computing may lie in negativity
Quantum computers hold great promise for applications from drug discovery to cybersecurity. Yet figuring out what would give quantum computers their edge over everyday "classical" computers is a subtle problem. A new theoretical ...
Medical Xpress / Q&A: Short animation changes how people see addiction
Social stigma—judgment from employers, neighbors, clinicians and family—is one of the main reasons why only one in 10 of the roughly 400 million people worldwide with alcohol or drug use disorders receive adequate care, according ...
Phys.org / Laser-cut aluminum foil could replace costly terahertz polarizers
When physicists at the ARC Centre for Transformative Meta-Optical Systems (TMOS) needed a key component for their terahertz experiments, they ran into a frustrating problem—they needed tiny optical devices, known as wire-grid ...
Phys.org / Human rights rankings reveal surprising over- and underperformers
When it comes to human rights, it probably won't surprise you that Scandinavian countries perform well by statistical measures, along with Canada and Australia. But did you know that Mozambique, the Philippines, and Rwanda ...
Phys.org / Astronomers catch hot birth of galaxy cluster more than 11 billion light-years away
Astronomers have detected an enormous cloud of gas tens of millions of degrees hot surrounding one of the most extreme structures known in the early universe. The study offers one of the clearest views yet of a galaxy cluster ...
Medical Xpress / How the brain distinguishes the consequences of our own choices from events beyond our control
A study led by the University of Oxford has identified the brain mechanisms that help us work out whether the consequences we experience are caused by our own actions or by circumstances beyond our control.
Phys.org / Thunderquakes enable seismic imaging of Earth's shallow subsurface
Seismic waves produced by thunderstorms, called thunderquakes, can be used as a novel source for seismic imaging, according to a new study led by researchers at Penn State.
Tech Xplore / Workers in China worry over being replaced as they adapt to the growing impact of AI on jobs
Computer programmer Fei Zhaojun's boss asked him if artificial intelligence could soon replace humans in coding jobs. Two weeks later, he was laid off from his job in Beijing, together with about 160 of his colleagues.
Medical Xpress / How shoulder replacement changes bone mineral density
Driven by the potential advantages of preserving bone stock and easier implant removal during revision surgery, the use of cementless short-stem implants in shoulder arthroplasty has increased in recent years. Despite this, ...
Phys.org / First 15 days of egg development may determine survival for California's most endangered salmon
Sacramento River winter-run Chinook salmon are California's most endangered salmon, with a single surviving population and an average of a few thousand returning fish in recent decades. Shasta Dam blocks their original habitat ...
Tech Xplore / AI agents can build consensus on a scale humans can't
Everyone is familiar with the situation: A larger group of people plans to visit a restaurant together, but it can take time and sometimes a great deal of patience to agree on a time and place to meet. The better the participants ...
Phys.org / Turning a quantum battery's environmental sensitivity into an advantage
Quantum batteries, devices that store energy by exploiting quantum mechanical phenomena, could, in principle, be charged faster and more efficiently than classical ones. Despite their potential, connecting these batteries ...
