How do you define good health – and achieve it – in a broken US medical system?

People with allergies must be able to travel without fear, and a compassionate society should respect that What are you most scared of? Perhaps snakes send a chill down your spine. Or heights leave your knees weak. Peanuts may sound like an odd source of phobia, but they have taken on an absurd bogeyman quality for me since my daughter was taken to hospital by ambulance after eating peanut butter when she was six months old. Just the sight of a bowl on a pub bar, or their shells discarded on the pavement, can raise my heart rate – even when I’m not with her. Nowhere is the sight of peanuts more confronting than at 30,000ft, especially now when millions are jetting back from their holidays. Travelling with a severely allergic child can be a nightmare for all sorts of reasons, but the idea you could be sat next to a passenger consuming the very thing that has hospitalised them is its own kind of hell.

Experts say findings mean breast screenings for cancer could also flag cardiovascular problems in women Doctors have discovered a way to use routine mammograms that screen for breast cancer to spot heart disease, the world’s leading – and frequently underdiagnosed – cause of death in women. Researchers analysed the scans using artificial intelligence and were able to successfully identify women with coronary heart disease, high blood pressure or who had suffered a stroke...

The pioneering Japanese artist talked openly about how her mental health and neurodivergence informed her creativity, paving the way for the likes of Turner prize winner Nnena Kalu Yayoi Kusama – who has died at the age of 97 – was 10 when she first started experiencing vivid hallucinations consisting of visual and aural disturbances, which she described as “flashes of light, auras, or dense fields of dots”. A drawing from 1939, of a woman in a kimono assumed to be her mother, shows her obliterated by those dots; they would become Kusama’s artistic obsession. She hallucinated flowers, too. “I was looking at the red flower patterns of the tablecloth on a table, and when I looked up I saw the same pattern covering the ceiling, the windows and the walls, and finally all over the room, my body and the universe”, she once said, when asked about that recurring motif. “I felt as if I had begun to self-obliterate, to revolve in the infinity of endless time and the absoluteness of space, and be reduced to nothingness.” For Kusama, art making was a means of survival. “I fight pain, anxiety, and fear every day, and the only method I have found that relieved my illness is to keep creating art. I followed the thread of art and somehow discovered a path that would allow me to live”, she said in a 2012 interview. In so doing, she became one of the most acclaimed and admired contemporary artists, staging happenings and influencing the pop art movement as a pioneering figure in the New York avant-garde. Her exhibitions and major retrospectives draw huge crowds. In 2022, due to enormous public demand, Tate Modern in London extended her Infinity Mirror Rooms show for a whole extra year (it ended up running until 2024)...
