A magnetic tool for removing kidney stones that's "sort of like using a stick to fish out a snot full of stone fragments" could mean fewer surgeries, and less pain, for people with the condition. www.newscientist.com/article/2502...

It can be hard to focus after a bad night's sleep...Now we may know why. It turns out that momentary lapses in attention may occur because the brain's trying to catch up with clearing out waste - something it usually does while we snooze. www.newscientist.com/article/2501...

Our bodies contain a ghostly web of thread-like vessels and bean-shaped nodes, called the lymphatic system. My latest cover story looks at how it could be a secret ingredient in treating some major health conditions from Alzheimer's disease to cancer. www.newscientist.com/article/2499...

Awesome story from @carissacwwong.bsky.social www.newscientist.com/article/2499...

The vast majority of long covid research has ignored how the condition may affect the menstrual cycle. Now a study suggests it may make periods longer and heavier. www.newscientist.com/article/2496...

Some of our immune cells fend off infections by undergoing an inflammatory form of cell death, but this may come at the cost of chronic inflammation later in life. www.newscientist.com/article/2496...

We’re spending more time on the loo 🚽because of smartphones 📱 - and that substantially increases the risk of getting piles, according to a small study 🧪 www.newscientist.com/article/2494...

Loved @davidarobson.bsky.social's latest column for @newscientist.com. I only started feeling comfortable in a swimsuit when I began appreciating my body for what it could do rather than how it looked. I am a big fan of the body-neutrality movement! www.newscientist.com/article/mg26...

You're probably familiar with the pain and peeling that comes with spending too much time in the sun, but what exactly is sunburn (hint: inflammation)? How can we treat it? And what are the long-term dangers? www.newscientist.com/article/2485...

It's costly and laborious to make the cells used in CAR T-cell therapy, a transformative treatment for some blood cancers. But a way of generating the therapy inside, rather than outside, the body could cut costs and make the treatment more accessible. www.newscientist.com/article/2485...

Tiny balls of lab-grown blood vessels restored blood flow to injured tissue in mice, suggesting the approach could help to minimise tissue damage that occurs after accidents or blood clots. www.newscientist.com/article/2484...

In my cover story for @newscientist.com this week, I dug into the fascinating new field of "cancer neuroscience". Scientists have found that tumours hack the nervous system to fuel their own growth - and disrupting this interplay could bring new treatments. www.newscientist.com/article/2482...

Gently massaging the face and neck with a device boosted the brain’s waste disposal system in mice, suggesting it could reduce the severity of conditions like Alzheimer’s disease. Read @newscientist.com. www.newscientist.com/article/2483...

Do ultra-processed foods contain especially high levels of microplastics that worsen mental health? That's the bold question being put forward by @ntfabiano.bsky.social and colleagues. So how plausible is the idea, and is it testable? Read @newscientist.com. www.newscientist.com/article/2481...

Microplastics, UPFs and mental health! A triple-whammy in this great analysis from @carissacwwong.bsky.social Given we don't actually know microplastics or UPFs are harmful, there is still a lot more work to do, but I find linking them intriguing www.newscientist.com/article/2481...
