This. Attacking the result rather than addressing the root of the problem gets people nowhere. Very few children are 'bad', they just have things going on that need support. Look at the difference Freddie Flintoff and positive reinforcement made with those young guys in Preston.
"You can't physically chuck a 13-year-old over a school gate and say: ‘Go on, get in.’"
Actor Anna Maxwell Martin, who's navigated the SEND system as a parent, tells #R4Today that attitude is just as important as funding to help support children with special educational needs.

Over half of ppl with MS are 50+, yet trials, treatment guidelines & diagnostic tools have not kept pace, say top neuros in "Call to Action" in @NatRevNeurol.
Result: diagnosis blind spots, under-treatment & missed opportunities.

Salt Path. Raynor Winn’s statement says “He’s got CBD and here are the doctors’ letters to prove it”. Some of which say “He hasn’t got CBD.” Did she just hope no-one would read them?

Vitamin D isn't just a vitamin—it's a steroid hormone that regulates over 5% of your entire genome
Yet over 70% of Americans don't have adequate vitamin D levels, severely limiting their immune function, mood regulation, and cognitive health
Clinical evidence points to blood levels of 40-60 ng/mL being the sweet spot
Supplementing with 4,000 IU daily typically moves people from deficiency to sufficient levels (in general, 1,000 IU raises blood levels by roughly 5–10 ng/mL)

In a two-year randomized controlled trial involving 573 older adults, daily multivitamin use slowed cognitive aging by two years. Improvements in episodic memory performance were even more striking, equivalent to ~five years of preserved memory function.
A larger meta-analysis of over 5,000 individuals across three trials confirmed these effects, showing consistent gains in global cognition and memory compared to placebo.
These findings are especially relevant given that most Americans have insufficient intake of multiple essential micronutrients. The multivitamin used in the study was not exotic - it contained 20 essential vitamins and minerals, along with the carotenoids lutein and lycopene, which are known to accumulate in the brain and retina and influence cognitive and visual function.
A daily multivitamin might actually reverse brain aging
The COSMOS study—a comprehensive meta-analysis of randomized controlled trials—found older adults taking a multivitamin were less likely to suffer memory loss and cognitive dysfunction
Moreover, their overall cognitive health improved measurably, equivalent to having a brain two years younger
Accessibility in learning is my thing and JASP is a fantastic (free!) stats programme to support learners and to provide extension to R for those who want it. If you are new to it, look at this guide by me and Dr Naneva, share and use! sheffield.pressbooks.pub/hel… @HETLAssociation

Good lord...we are still talking about the dangers of concussions?? It's NOT concussions that are the problem, it's the long term exposure to Repetitive Head Impacts thst is causing the damage. Lowering exposure is the ONLY way to lower risk. WAKE UP

In 1945, six women pulled off a computing miracle.
They programmed the world’s first computer—with no manuals, no training.
Then, a SINGLE assumption erased them from tech history for decades.

“This is a global game, it really needs FIFA to take a lead on this.”
Dr Willie Stewart, a leading expert in brain injuries in sports, says the international football governing body needs to provide better safeguards for head injuries in the game.
