Firm says results of research create ‘path to medical superintelligence’ but plays down job implications
Microsoft has revealed details of an artificial intelligence system that performs better than human doctors at complex health diagnoses, creating a “path to medical superintelligence”.
The company’s AI unit, which is led by the British tech pioneer Mustafa Suleyman, has developed a system that imitates a panel of expert physicians tackling “diagnostically complex and intellectually demanding” cases.

These supposedly serious cetaceans have been spotted massaging each other with kelp stalks. This is the sort of performative nonsense you’d expect from dolphins
I’ve thought for a while that it would be nice to be an orca. Not because I hate boats and they sink them (though I get it – the briny depths are none of our human business). What actually appeals is the idea of being charismatic megafauna – I love that phrase – and also important as a post-menopausal female. Orcas are one of very few species that go through menopause, living for decades after their reproductive years. These older matriarchs remain an integral part of the community, improving pod survival rates thanks to being “repositories of ecological knowledge”, caring for young and even, research suggests, keeping their giant adult sons safe from being attacked. The fact that they’re fashion-conscious is a bonus: the 80s orca trend for wearing jaunty salmon fascinators was revived, intriguingly, in some pods last December; other orcas have been observed draping themselves artistically in kelp.
But new research is giving me pause. Now orcas in the Salish Sea off the coast of Washington state have been filmed picking kelp stalks and “massaging” each other with them. In sightings of this behaviour, reported and dubbed “allokelping” by the Center for Whale Research, “the two whales then manoeuvre to keep the kelp between them while rolling it across their bodies … During contact, whales roll and twist their bodies, often adopting an exaggerated S-shaped posture.”

Occasional sensitivity to lactose can occur as we get older, or through stress, but for most people it’s only temporary
Most of us aren’t inherently dairy intolerant, but we can go through periods where we become more sensitive to lactose in our diet, says Amanda Avery, an associate professor in nutrition and dietetics at the University of Nottingham.
She says that when people talk about being “dairy intolerant”, they’re usually referring to lactose, the sugar found in milk and dairy products, such as milk, cheese and yoghurt. In most people, that sugar is broken down by an enzyme called lactase, which is found in our small intestine. It helps our bodies digest and absorb lactose without causing discomfort. “We’re born with plenty of lactase. But as our diets diversify, our lactase levels decline,” says Avery. “If there is minimal milk in the dairy diet then lactase levels may be zero, thus people from some cultural backgrounds and countries where dairy intake is negligible may be intolerant.”

Does a good apology contain five steps, seven steps – even eight? And why do we find it so difficult?
Got something to say sorry for? Here are words that have no place in your apologies, according to those who have spent years analysing them: “It was not my intent”. “What I meant was”. “Sorry you misunderstood”. And any use of the word “obviously”.
Marjorie Ingall and Susan McCarthy call it “bad apology bingo”. They have heard a lot of them as co-authors of Sorry, Sorry, Sorry: The Case for Good Apologies and the blog Sorrywatch, where they critique public apologies. “We’ve looked at so many studies, from so many different fields, on what makes an effective apology,” Ingall says.

With close encounters due in 2029 and 2032, space scientists are getting to grips with an existential threat
It is a scenario beloved of Hollywood: a huge asteroid, several miles wide, is on a collision course with Earth. Scientists check and recheck their calculations but there is no mistake – civilisation is facing a cataclysmic end unless the space rock can be deflected.
It may sound like science fiction, but it is a threat that is being taken seriously by scientists.
