Did breakthrough in US fentanyl crisis start in China?

As Donald Trump travels to Beijing this week, fentanyl – and China’s role in its supply chain – remains an enduring point of acrimony in bilateral relations.At a UN meeting in March, the US again accused China of failing to stop its chemical industry selling the precursors required to make the potent synthetic opioid, while China suggested the US was shifting the blame for its domestic drug problem.Yet there are growing signs that the US fentanyl crisis has turned a corner – and some experts believe that interventions made in China have played a key role.“There was a supply shock: the purity of fentanyl fell,” said Keith Humphreys, a professor at Stanford University. “The question is why was there a supply shock

Getting children to eat their vegetables starts in the womb, researchers suggest

Rather than bribery, or hiding carrots under ketchup, the key may be to expose foetuses to healthy flavoursIt is an age-old battle with small children that most parents will recognise: please, please, eat your vegetables.Some will read them books with titles such as The Boy Who Loved Broccoli. Others have been known to smother veg in tomato ketchup, or mix avocado and fruit with Greek yoghurt and call it icecream. Or resort to plain bribery.Now, a study suggests there may be a more effective approach – but mothers need to start early

Older people risk mental decline if they do long hours of caring, UK study shows

The stresses and strains of caring for someone for 50 hours or more a week leads to “accelerated cognitive decline” in middle-aged and older people, research shows.However, providing care for only five to nine hours a week has the opposite effect, boosting brain health so much that the benefits last until older age.Carers UK called the findings “extremely worrying” and said they highlight how long hours spent providing care raises the risk of social isolation and burnout.Dr Baowen Xue, an academic at University College London and the lead author of the paper, said: “Our study shows that the caring responsibilities many people take on in later life can be a double-edged sword.“On the one hand, lighter caring responsibilities can be good for you by providing mental stimulation from interacting with loved ones or others you’re helping and a sense of purpose and usefulness

Capacity of lifts not kept up with UK obesity levels, study shows

Lifts are no longer big enough to fit the UK’s larger citizens, according to researchers.A study of maximum capacity in elevators in the UK and mainland Europe found lifts have not kept up with increasing obesity levels, raising concerns about safety and equity.The research, presented at the European Congress on Obesity in Istanbul, Turkey, used photos of weight limits for 112 lifts manufactured between 1972 and 2024 in the UK, France, Germany, Italy, Spain, Austria and Finland.Prof Nick Finer, the president and chair of the International Prader-Willi Syndrome Organisation and lead author of the study, compared the average maximum weight allowance (total weight allowance divided by maximum passenger limits) with the average adult weight in the year the lift was manufactured.The research found that despite adults’ continued growing weight, total lift limits have not increased since about 2004

More than 6,000 children treated at obesity clinics in England, figures show

More than 6,000 children living with obesity, including hundreds as young as four, have required treatment at specialist NHS weight-loss clinics, new figures reveal.NHS England data, published for the first time, underlines the scale of the growing childhood obesity crisis.Since the first Complications from Excess Weight clinic (CEW) opened in 2021, the NHS has treated 6,497 children and teenagers. Of these, 423 were four years old, 1,088 were aged between five and eight, 1,791 were aged nine to 12 and 3,137 were aged between 13 and 17. The age of a further 58 is unknown

Consuming fruit and a cup of coffee a day can halve risk of unhealthy cell ageing, study suggests

Eating fruit and drinking a cup of coffee a day could halve the risk of cells ageing unhealthily, research suggests.Foods rich in polyphenols such as berries, apples, coffee, cocoa and tea are known to have antioxidant and anti-inflammatory properties, but a new study has found they are also associated with a lower risk of short telomeres, the “ends” or caps of DNA that, when shorter, increase the risk of cell death and unhealthy ageing.Researchers from the University of Navarra in Pamplona, Spain, measured the length of telomeres in samples from more than 1,700 adults in 2008 and also in 2015 and assessed participants’ total polyphenol consumption.The study, presented at this year’s European Congress on Obesity in Istanbul, found that compared with those who consumed the least polyphenols, those with the highest amounts in their diets had a 52% lower risk of short telomeres.Moderate coffee consumption (up to one cup per day) was associated with a 26% lower risk of short telomeres compared with non-consumers, while four to five servings of fruit a day was also linked to a lower risk, with participants consuming the most fruit having a 29% lower risk of having short telomeres compared with those who ate the least

Palantir’s access to identifiable NHS England patient data is ‘dangerous’, MPs say

MPs have warned that an NHS decision to grant Palantir access to identifiable patient information in its plan to use AI to improve the health service is “dangerous” and will fuel public fears that data privacy is not being prioritised.NHS England has allowed staff from the US tech firm and other contractors to access patient data before it has been pseudonymised, despite internal fears of a “risk of loss of public confidence”, the Financial Times reported.The health service made the move to allow Palantir to access the data in recent weeks according to the reports, which revealed an internal NHS briefing that said it would allow “unlimited access to non-NHSE staff” to part of the NHS’s federated data platform (FDP), which holds identifiable patient information.Palantir, which also supports Donald Trump’s ICE immigration crackdown and the Israeli, US and UK militaries, was awarded a £330m contract to help build the FDP, installing AI systems to integrate scattered health datasets and bring efficiencies to medical treatment. But the deal has been dogged by warnings from campaigners and MPs concerned about the security of patient records

‘The mouth is a gateway into your body’: the fascinating, frightening links between our gums and our health

Scientists are discovering more and more associations between poor oral health and everything from heart disease to dementia. But can flossing and brushing properly guarantee a longer life?Isn’t it weird that dentistry and medicine have been kept largely separate? Why should our mouths be treated differently from the rest of our bodies? Going to the dentist often feels like more of a lifestyle and cosmetic add-on, especially for adults in the UK. And, even if you can find an NHS dentist, the service is not free at the point of use like medical doctors are.The origin story for this rift is that dentistry began, in the middle ages, as a trade – with tooth extractions handled by “barber surgeons” and dentures crafted by jewellers and blacksmiths. Today, dentistry and medicine still have their own separate training routes, professional bodies and NHS setup

Experts call for UK four-day week as study links long work hours to obesity

Those who work longer hours are more likely to be obese and cutting how much time you spend working could help you keep the weight off, research suggests.International research presented at the European Congress on Obesity in Istanbul compared working patterns and obesity prevalence for 33 OECD countries from 1990 to 2022. The study found that countries such as the US, Mexico and Colombia, which have longer annual working hours, also had higher obesity rates, even though northern European countries consume more energy and fat on average than those in Latin America.Reducing annual working hours by 1% was associated with a 0.16% decrease in obesity rates
