Fresh ‘quantum advantage’ claim made by computing firm D-Wave
A ‘quantum processor’ has solved a physics problem on the behaviour of magnetism in certain solids that would take hundreds of thousands of years to calculate on the largest conventional supercomputers. The result is the latest claim of machine showing ‘quantum advantage’ over classical computers. Although Google and others have claimed to achieve quantum advantage…

Did Mars harbour life? One of the strongest signs yet is spotted in a peculiar rock
The black-ringed ‘leopard spots’ on a Martian rock might be evidence of chemical reactions that could have involved micro-organisms. Credit: NASA/JPL-Caltech/MSSS NASA’s Perseverance rover has found possible hints of ancient life on Mars― one of the strongest signs yet of Martian life, according to planetary scientists. Dark-rimmed ‘leopard spots’ in a rock studied by the…

Alcohol and cancer risk: what you need to know
Early this year, the US surgeon general issued a bombshell report. Before his term ended in January, Vivek Murthy warned that alcohol increases the risk of at least seven types of cancer and called for alcoholic drinks to carry cancer warning labels as cigarette packs do. The report1 triggered a flurry of headlines about a…

Quantum Glitches: Scientists Catch Nature’s ‘State Changes’ in Superconducting Circuits
In a significant advancement for quantum science, researchers have successfully observed both first and second-order dissipative phase transitions in a superconducting quantum system—a feat that could reshape future quantum computing technologies. The study, published March 10 in Nature Communications, documents how a team led by Professor Pasquale Scarlino at EPFL (École Polytechnique Fédérale de Lausanne)…

Why we organized ‘Stand Up For Science’
In the USA, the Trump administration has signed executive orders that impose censorship on key areas of scientific research, strip government scientists of their jobs and reduce federal funding for science. Five co-organizers of the nationwide Stand Up For Science movement explain the need for collective action at this time. Download PDF Credit: Emma Courtney.…
