How the mind and body work — brain, sleep, stress, habits and health — in plain English.
England's health secretary asks for an urgent plan to end corridor care for children, as 12-hour A&E waits reach 50,582 a month →
Yvette Cooper asked NHS England for urgent plans to stop children being treated in hospital corridors, and announced £140m for urgent care, as 12-hour waits for a bed rose to 50,582 in September.
US women's doctors update menopause advice for the first time since 2014, calling hormone therapy safe for most women under 60 →
A co-author of ACOG's new guidance calls hormone therapy probably the best option for women with symptoms who are under 60 or within 10 years of their last period, 22 years after a US warning drove most women off it.
NHS England tells hospitals to put trans patients on wards by biological sex, with medical need first, as mixed-sex ward breaches reach 5,520 a month →
New guidance published on Thursday says single-sex wards, toilets and changing rooms go by biological sex, and leaves the hardest cases to staff on the ward.
Eight US states sue OpenAI, saying ChatGPT harmed children and coached people towards suicide →
Arizona, Arkansas, Idaho, Iowa, Kansas, Montana, Nebraska and West Virginia each sued the maker of ChatGPT on Wednesday, saying a chatbot built to agree and sound caring misled families about its safety.
Women with autoimmune diseases are more often told their symptoms are psychological, and wait one to two years for a diagnosis, a survey of more than 6,600 patients finds →
In a Cambridge and East Anglia survey, women were 74% more likely than men to report being told their illness came from stress or anxiety, and the most common wait for a diagnosis was one to two years for women against under three months for men.
Menopause changes bone, liver and blood fat tests in one sudden step, not a slow slide, a study of 300 million lab tests finds →
Researchers lined up more than a million women by the time since their final period instead of by age, and 52 of 90 common blood and body tests jumped at that moment while men's did not.
US maternity wards close as Medicaid cuts take effect: 52 shut since the law passed in July 2025, eight more announced →
A US campaign group counts 52 birth wards closed since the law cutting Medicaid was passed, and the charity March of Dimes names 31 more rural ones at risk, while the federal survey that tracked mothers' health has been stopped.
The US food regulator's draft rule would let some chemicals be added straight into food without a safety review, if each stays under 0.5 parts per billion →
A rule sold in August as closing one food-safety loophole also widens another, campaigners found. Elsewhere, US reporters counted over 1,000 eye-damage reports on weight-loss drugs, and a world survey measured trust in science.
A Danish ethics panel and Guinea-Bissau approve a US-funded trial that delays the hepatitis B vaccine for half of 14,000 newborns →
Half the babies would wait six weeks for a vaccine the WHO says every newborn should get at birth, and four members of the Danish committee resigned over the vote.
England's mental health review says young people's distress is real, and help should no longer wait behind a diagnosis →
A 607-page review of mental health, ADHD and autism care in England found that distress has truly risen, that more than 800,000 people are waiting for an assessment, and that a diagnosis has become the only way to get help. It asks for help based on need instead.
Canada will keep people whose only illness is a mental illness out of assisted dying, with no end date →
Canada's government dropped a plan to open assisted dying to people with only a mental illness in March 2027, saying doctors cannot agree such an illness is beyond help; a gene therapy also restored some sight to blind patients.
Flu is rising about a month early in the US West, with a changed strain, and experts disagree on whether the season is unusual →
Flu tests and emergency visits have climbed since early September in California, Washington, Hawaii and Alaska, and Seattle doctors see a mutated strain. Others call it a normal start, and the US disease agency has said little.
Karl Deisseroth, Peter Hegemann and Georg Nagel win the medicine Nobel for a way to switch chosen brain cells on and off with light, using a protein from a green alga →
The 2026 Nobel Prize in Physiology or Medicine rewards optogenetics, a tool that lets scientists turn chosen nerve cells on or off and see what each one does.
Tau threads from Alzheimer's brains turned a mouse's own tau into the same shape, the way prions spread →
Scientists in Cambridge injected tau threads from patients' brains into ordinary mice, and the mice's own tau folded into the patients' shape, which backs the idea that the disease spreads by copying.
WHO says people now live almost as long as before COVID, while dementia has climbed from the 19th to the 5th biggest cause of death →
WHO's new estimates put life expectancy worldwide at 73.3 years in 2023, close to its 2019 level. Years lived in good health have not fully recovered, deaths from dementia have tripled since 2000, and anxiety and depression rose sharply per person after 2019.
Christa Pike survived two doses of the sedative meant to execute her, and Tennessee has stopped executions while it finds out why →
Pentobarbital kills by quieting the part of the brain that runs breathing. Her lawyers say it went under the skin of her arm instead of into a vein, and she is on a ventilator.
People who use cannabis were about twice as likely to commit violence, in a review of 63 studies of more than 265,000 people →
Users were also about one and a half times as likely to suffer violence. The review shows a link, not a cause, and most of its studies came before today's stronger cannabis.
Scientists replaced half of a mouse's brain with human brain cells, to study illnesses that mice do not get →
A Stanford team bred mice with almost no cortex of their own and filled the gap with lab-grown human brain tissue, which wired itself into the mouse's brain and spinal cord.
The largest map yet of the brain's planning area reads which genes are switched on in 6.3 million cells from 1,494 donated brains →
Eight brain illnesses, from Alzheimer's to schizophrenia, share some cell changes and not others, and a healthy brain changes fast in early life and again from about 65. Also today: Fiji's HIV emergency, why weight-loss drugs fail some people, and a shingles vaccine linked to fewer heart problems.
Infections caused about one new cancer in eight in 2024, IARC estimates, and it says most could already be prevented →
The WHO's cancer agency counts 2.3 million cancers from 12 germs, led by the stomach bacterium H. pylori and HPV. Also today: fewer sad US teens, 175,000 menthol letters, metals in Maui residents and hearts that take on their new body's age.
Rabies almost always kills once symptoms start. This month WHO confirmed Bhutan and Chile had stopped dogs passing it to people →
Rabies is carried by dogs and kills almost everyone who gets symptoms. WHO confirmed this month that Bhutan and Chile have ended human deaths from it, by vaccinating their dogs over many years.
A review of 76 trials found that stopping an antidepressant slowly, with talking therapy alongside, kept depression away about as well as staying on it →
The US health secretary, Robert F. Kennedy Jr., has started a push to get Americans off antidepressants. How a person stops matters, because a fast drop can bring withdrawal symptoms or the illness back.
Bowel cancer in people under 50 has risen about 2% a year since the 1990s, and excess weight explains only 20 of every 100 extra cases →
Colorectal cancer is now the leading cause of cancer death among Americans under 50. Smoking, drinking and diet all improved while the cases climbed, so researchers are now looking at gut bacteria and at what happens in childhood.
Hepatitis B caught at birth tends to stay for life, and in 2024 only 45% of newborns got the vaccine dose due in their first day →
A WHO report says hepatitis B deaths rose 17% since 2015 while new infections fell by a third. Most lifelong infections start in the first five years of life, and the first vaccine dose is meant to arrive within 24 hours of birth.
Alzheimer's drugs clear a protein from the brain, and a review of 17 trials found the difference too small for patients to notice →
Two drugs that pull amyloid out of the brain slow decline by about four to six months over a year and a half, while blood tests that find the illness years early are arriving faster than treatments.
Ebola vaccines teach the body the shape of the virus's outer protein, and the Ebola spreading in Congo has a different one →
Congo has confirmed 6,757 Bundibugyo Ebola cases and 3,267 deaths since May, and the only licensed Ebola vaccine was made for a different species of the virus. Also today: US overdose deaths fell for a third year, a second weight-loss pill was approved, and more studies found no link between paracetamol in pregnancy and autism.
An injection given twice a year now stops HIV, and the town in Uganda that helped prove it has already run out →
Lenacapavir protects for six months from one jab, and 120 poorer countries are due cheap copies from 2027. Across today's edition the drugs and vaccines work; what keeps failing is the money and the delivery behind them.
Antivenom has worked for a hundred years, and in the Amazon what decided who lived was how far away it was kept →
Snake venom kills up to 138,000 people a year and the treatment is old, cheap and on the WHO's list of essential medicines. In four Indigenous districts of the Brazilian Amazon it was moved out of city hospitals and into village health units, and the share of patients treated within six hours went from two in five to three in four.
A seizure is a sudden burst of abnormal electrical activity, and after two medicines fail the next one works for about one person in 25 →
Half of people with epilepsy stop having seizures on the first medicine they try. After two have failed, the chance the next one works is about 4%, and more than thirty medicines have not changed that.
Coeliac disease is the gut's defences attacking wheat, and most people who have it have never been tested →
In coeliac disease, pieces of gluten the stomach cannot break down set off an immune attack on the gut lining. New UK rules from July 2026 let some adults skip the biopsy, but an estimated 75% to 83% of people with the disease have never been diagnosed.
Nearly everyone carries the virus behind glandular fever, and in multiple sclerosis the immune cells hunting it also attack the coating on the nerves →
Multiple sclerosis almost never happens without an earlier Epstein-Barr infection. New studies show how the virus points the immune system at the coating of the nerves, and why some researchers now want antivirals tested.
When the top of the heart quivers, blood sits still and can clot - and watches now find short episodes nobody knows whether to treat →
In atrial fibrillation the heart's upper chambers quiver instead of beating, and the stroke risk depends on how long it lasts. Smartwatches find far more of it, and trials have not shown the shortest episodes are worth treating.
These children's ears detected sound perfectly and passed none of it on - the missing piece was one protein, and a virus has put it back →
The US regulator approved the first gene therapy for deafness in April, on a study of twelve children. Nine of them reached a hearing level that normally avoids a cochlear implant.
Grief is the brain still expecting someone who has died, and for up to one bereaved person in ten it does not ease →
Prolonged grief became a diagnosis only in the last few years, the rules still count only human deaths, and the loss shows up in blood pressure, heart deaths and care homes.
In sleep apnoea the throat muscles go slack and the airway shuts, and the mask that holds it open works only for the hours it is worn →
A mask that pushes air into the throat stops almost every blocked breath, but people wear it for about half the night, so pills and a weight-loss injection are now being tested on those who take it off.
Migraine is a slow wave across the brain and a messenger released outside it - and the drugs that stop it barely enter the brain →
The brain cannot feel pain; the ache comes from its covering, where a messenger called CGRP fires the nerve. The new drugs block it there, and a first narcolepsy drug aimed at the cause was approved.
