of drugs in its arsenal. If you are unwell, thereis avery good chance your doctor will prescribe a pill to get you back to health. What our medical system is less good at, however, is stopping medication.  \nTake antidepressants. The drugs aren’t effective for everyone, but they work well for some. Once the medication does its job, though, orthe life circumstances that broughton depression grow easier–what then? We don’t yet have a good answer.  \nBecause antidepressants are relatively safe drugs, they can often be dispensed for months or years on end, without much consideration about the long-term implications, as we discuss on page 36. But thousands of people struggle to stop taking them, with little help from doctors.  \nPUBLISHING & COMMERCIAL  \nDisplay advertising  \nTel +44 (0)203 615 6456 [Email](Email displayads@newscientist.com)[ displayads@newscientist.com](Email displayads@newscientist.com)[ ](Email displayads@newscientist.com)Sales director Claudia Nicoletti Partnership growth lead Joe Teal Agency partner Daniel Sinclair  \nNew Scientist Events  \nTel +44 (0)[203 615 6554](203 615 6554 Email live@newscientist.com)[ Email](203 615 6554 Email live@newscientist.com)[ live@newscientist.com](203 615 6554 Email live@newscientist.com)[ ](203 615 6554 Email live@newscientist.com)Sales director Jacqui McCarron Sales manager Maureen Ignacio Head of product delivery Henry Gomm Events and projects manager Georgia Hill Events and projects executive Ciara Lucas  \nNe","cbCaiehEBN2hVSQm","https://ap.wps.com/l/cbCaiehEBN2hVSQm","pdf",14548686,52,"English","# News\n## Fresh light on dark matter\n## Heating up\n## Like father, like daughter\n## Sleepy neurons\n# Views\n## Our upper limit\n## The Void Ages\n## Aperture\n## Book of the week\n## Letters\n# Features\n## Poking holes in reality\n## The antidepressant trap\n## Most dangerous algorithm\n# Back pages\n## Puzzles\n## Almost the last word\n## Tom Gauld for New Scientist\n## Feedback\n## Twisteddoodles for New Scientist","[{\"question\":\"What major topics are covered in this New Scientist issue?\",\"answer\":\"It covers immune cells in the world’s oldest people, European heatwaves intensified by ice melt, quantum theory, next-gen bananas, and why long-term antidepressant use may need rethinking, alongside other featured science questions.\"},{\"question\":\"Why does the issue discuss long-term antidepressant use as needing a rethink?\",\"answer\":\"It highlights that antidepressants can be used for months or years with limited long-term consideration, while withdrawal symptoms after long-term SSRI use appear more serious than previously thought.\"},{\"question\":\"How does the issue connect quantum theory to everyday understanding?\",\"answer\":\"It argues that quantum theory can finally make sense if irrational numbers are examined within the framework, asking what would happen if they were removed from quantum mechanics.\"}]","New Scientist 29 August 2026 - Vol 271 No 3610 | PDF",131]
