Lack of symmetry in qubits can’t fix errors in quantum computing, might explain matter/antimatter

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 matter and antimatter in the universe…

Are Experts Underselling the Effectiveness of Covid-19 Vaccines?

David Leonhardt won a Pulitzer Prize for commentary in 2011.

Folding@Home Exascale Supercomputer Finds Potential Targets For COVID-19 Cure

An anonymous reader quotes a report from Network World: The Folding@home project has shared new results of its efforts to simulate proteins from the SARS-CoV-2 virus to better understand how they function and how to stop them. Folding@home is a distributed computing effort that uses small clients to run simulations for biomedical research when users’ PCs are idle. The clients operate…

Scientists Win Historic Nobel Chemistry Prize for ‘Genetic Scissors’

Two scientists have been awarded the 2020 Nobel Prize in Chemistry for developing the tools to edit DNA. Emmanuelle Charpentier and Jennifer Doudna are the first two women to share the prize, which honours their work on the technology of genome editing. From a report: Their discovery, known as Crispr-Cas9 “genetic scissors”, is a way of making specific and precise changes…

Hydroxychloroquine Advocate Angry Donald Trump Took ‘Experimental Antibody Stupidness’

“A doctor notorious for claiming hydroxychloroquine is a ‘cure’ for COVID-19 has denounced White House doctors for not giving President Donald Trump the drug to treat his infection…” reports Newsweek. “Other unsubstantiated claims from Immanuel include declarations that fasting can cure those affected by ‘witchcraft,’ that having sex with demons while dreaming can cause gynecological problems and that certain medications contain…
