Will your child become obese as an adult? New tool identifies those genetically at risk
This new resource may one day mean that those at highest risk will get targeted support to prevent them from becoming obese in the first place.
The tool, which assesses a person's
genetic risk of obesity , works twice as well as any other obesity risk predictor, academics said.
As well as identifying children at risk, it can also predict how well obese adults will respond to targeted weight-loss programmes.
Academics used data on the genetic variations from more than 5 million people to create a tool called a polygenic risk score, which analyses millions of DNA variations to predict a person's susceptibility to becoming overweight.

The tool could explain 17.6 per cent of the variation in the body mass index score (BMI) – calculated from a person's weight in kilograms divided by the square of their height in metres – from people in the UK, they found.

Are microplastics damaging our brains and our health? Experts say they do not yet know
Tiny shards of plastic called microplastics have been detected accumulating in human brains, but there is not yet enough evidence to say whether this is doing us harm, experts have said. Advertisement These mostly invisible pieces of plastic have been found everywhere from the top of mountains to the bottom of oceans, in the air we breathe and the food we eat. They have also been discovered riddled throughout human bodies, inside lungs, hearts, placentas and even crossing the blood-brain barrier. The increasing ubiquity of microplastics has become a key issue in efforts to hammer out the world's first plastic pollution treaty, with the latest round of UN talks being held in Geneva next week. Microplastic waste is seen among sand at a beach. Photo: Shutterstock The effects that microplastics and even smaller nanoplastics have on human health are not yet fully understood, but researchers have been working to find out more in this relatively new field.

‘Absolutely impossible': how China created super steel for nuclear fusion
In the quest to harness the power of the stars, one of the greatest challenges lies not in mastering fusion , but in finding materials strong enough to contain it. Advertisement At the heart of a nuclear fusion reactor is an ultra-powerful superconducting magnet, operating at temperatures near absolute zero and under immense magnetic stress. For decades, scientists from around the world have struggled to find materials that simultaneously endure such extreme cold and extreme force. Chinese scientists have detailed how they created CHSN01 (China high-strength low-temperature steel No 1), deployed it this year in the construction of world's first fusion nuclear power generation reactor and put China in a leading position in materials science. 02:24 A look inside the world's largest nuclear fusion reactor in Japan A look inside the world's largest nuclear fusion reactor in Japan It was a decade-long journey marked by setbacks, doubt and ultimate triumph. In 2011, the International Thermonuclear Experimental Reactor (ITER), which is under construction in southern France, faced a critical material challenge. Testing revealed that the cryogenic steel prepared had become brittle and lost its ductility. ITER, the world's largest fusion experiment, was launched in 2006 from a collaboration between seven members, including China. Advertisement At the core of the fusion device, superconducting magnets are armoured with cryogenic steel, like a jacket engineered to endure ultra-low temperatures. This material must withstand both liquid helium's 269 degrees Celsius (516 Fahrenheit) cryogenic environment and the massive Lorentz forces generated by intense magnetic fields.

Are you a highly sensitive person? How you can tell and why it can be a gift
Has anyone ever told you to 'stop being so sensitive' or to 'toughen up'? If you are regularly accused of being too sensitive, you may be a highly sensitive person (HSP), among an estimated 15 to 30 per cent of the global population. 'I was told my entire life I was oversensitive, or being overdramatic,' says Catherine Asta, an author, psychotherapist, and founder and host of The Late Discovered Club, a podcast that gives voice to autistic women. Asta is autistic , something that was identified late in her life. 'Over time, you learn to mask to protect yourself in all the spaces, faces and places that make it feel unsafe to be you.' It was not until she was in her thirties, after a period of repeated burnout , that Asta realised she had to change her lifestyle and the way she worked. Based in the United Kingdom, she trained to become a psychotherapist and is now writing her second book. Psychotherapist Catherine Asta works with others who have felt 'differently wired' all their lives without knowing why. Photo: Catherine Asta Her story, she saw, was not uncommon. Now she works with people – some in their seventies and eighties – who have felt 'differently wired' all their lives without knowing why.
