Wildfire smoke is more cooling on climate than computer models assume — ScienceDaily

A study of biomass burning aerosols led by University of Wyoming researchers revealed that smoke from wildfires has more of a cooling effect on the atmosphere than computer models assume. “The study addresses the impact of wildfires on global climate, and we extensively used the NCAR-Wyoming supercomputer (Cheyenne),” says Shane Murphy, a UW associate professor […]

Best computer speakers: Make music, video chats, and more a whole lot clearer

Elevate your audio with these great computer speakers. (Sebastian Bednarek via Unsplash/) Let’s face it: The audio capability of your PC, laptop, tablet, or smartphone probably isn’t anywhere near powerful enough to get the party started. Sure, many computers deliver sound that might be passable if you’re watching a tutorial, catching the latest viral video, […]

New findings from theoretical computer science — ScienceDaily

We are fascinated by machines that can control cars, compose symphonies, or defeat people at chess, Go, or Jeopardy! While more progress is being made all the time in Artificial Intelligence (AI), some scientists and philosophers warn of the dangers of an uncontrollable superintelligent AI. Using theoretical calculations, an international team of researchers, including scientists […]

Review of cognitive testing studies reveals how adding computer simulations could help — ScienceDaily

The introduction of computer simulation to the identification of symptoms in children with attention deficit/hyperactivity disorder (ADHD) has potential to provide an additional objective tool to gauge the presence and severity of behavioral problems, Ohio State University researchers suggest in a new publication. Most mental health disorders are diagnosed and treated based on clinical interviews […]

Important milestone in the creation of a quantum computer — ScienceDaily

Quantum computer: One of the obstacles for progress in the quest for a working quantum computer has been that the working devices that go into a quantum computer and perform the actual calculations, the qubits, have hitherto been made by universities and in small numbers. But in recent years, a pan-European collaboration, in partnership with […]

Researchers claim quantum supremacy with new light-based quantum computer

The quantum computer named Jiuzhang was able to complete a task 100 trillion times faster than one of the world’s fastest super computers. In an exciting new development, a team of researchers from multiple institutions in China claim to have achieved quantum supremacy (or the more accepted term quantum advantage) with their quantum computer called […]

China claims fastest quantum computer in the world

A team of Chinese scientists have developed the most powerful quantum computer in the world, capable of performing at least one task 100 trillion times faster than the world’s fastest supercomputers. In 2019, Google said it had built the first machine to achieve “quantum supremacy,” the first to outperform the world’s best supercomputers at quantum […]

Light-based quantum computer Jiuzhang achieves quantum supremacy

A new type of quantum computer has proven that it can reign supreme, too. A photonic quantum computer, which harnesses particles of light, or photons, performed a calculation that’s impossible for a conventional computer, researchers in China report online December 3 in Science. That milestone, known as quantum supremacy, has been met only once before, […]
