NASA’s Perseverance Rover Spots Megaripples, Proof Mars’ Soil Is Still Shifting

NASA’s Perseverance rover has discovered striking megaripples — giant Martian sand waves — at a site called Kerrlaguna in Jezero Crater. These formations, about a meter tall, are larger than Earth’s beach ripples but smaller than the biggest dunes. Scientists say they formed when Mars had a thicker atmosphere and stronger winds, and many now appear frozen in time, shifting only about a meter every nine Earth years.

The Big Idea: why we should embrace AI doctors

People are understandably wary of new technology, but human error is often more lethal

We expect our doctors to be demi-gods – flawless, tireless, always right. But they are only human. Increasingly, they are stretched thin, working long hours, under immense pressure, and often with limited resources. Of course, better conditions would help, including more staff and improved systems. But even in the best-funded clinics with the most committed professionals, standards can still fall short; doctors, like the rest of us, are working with stone age minds. Despite years of training, human brains are not optimally equipped for the pace, pressure, and complexity of modern healthcare.

Given that patient care is medicine’s core purpose, the question is who, or what, is best placed to deliver it? AI may still spark suspicion, but research increasingly shows how it could help fix some of the most persistent problems and overlooked failures – from misdiagnosis and error to unequal access to care.

‘They had everything, then nothing’: the prodigies the art world forgot

Robert Colquhoun and Bobby MacBryde were once the golden boys of London’s art scene – photographed in Vogue, filmed by Ken Russell and lauded by Francis Bacon. So why did they vanish into obscurity?

The world is burning. Fascism is rising. Countries are falling. And we’re on the brink of incredible technological change, which will either be the end of everything or a new beginning. So, who needs artists?

An August night in 1944. Robert Colquhoun’s hand shakes as he lights a candle in the blacked-out Notting Hill studio shared with his lover, fellow artist, Robert “Bobby” MacBryde. They are known – from Soho alleys to Bond Street galleries – as the Two Roberts: inseparable, incandescent, often in trouble. Where is Bobby tonight? The Colony Room Club, probably. Safe, Robert hopes. Though never from himself. Bombers prowl the skies above. Who will survive the night? “Fuck it,” Robert mutters, fag dancing on his lip. And he picks up his brush.

Caltech Scientists Stretch Quantum Memory Lifetimes 30x in Major Leap

Caltech scientists developed a hybrid quantum memory that stores qubit states 30 times longer by converting them into sound waves. The method, using mechanical oscillators at gigahertz frequencies, reduces energy loss and shows scalability potential. Published in Nature Physics, the breakthrough marks a step toward practical, long-term storage for superconducting quantum computers.
