A number of days in the past I watched, amazed, a video of a person paralysed from the waist down going for a stroll outside. 

Utilizing a body as assist, he was capable of transfer below his personal steam because of {an electrical} gadget surgically implanted in his backbone.

The affected person, a 29-year-old Italian referred to as Michel Roccati, had been badly injured in a motorbike accident in 2017, however work by researchers from the Swiss Federal Institute of Expertise in Lausanne meant he might now stroll, utilizing a pc pill wirelessly linked to the implant to stimulate the nerve cells — neurons — in his spinal wire.

‘The primary few steps have been unbelievable — a dream come true!’ he mentioned. ‘I’ve been by way of some fairly intense coaching up to now few months, and I’ve set myself a collection of targets.

Utilizing a body as assist, he was capable of transfer below his personal steam because of {an electrical} gadget surgically implanted in his backbone 

‘For example, I can now go up and down stairs, and I hope to have the ability to stroll one kilometre by this spring.’

This ‘medical miracle’ is the fruits of analysis on implants that have been initially developed over 30 years in the past to dam ache alerts travelling down the backbone. In reality, this therapy is obtainable on the NHS to sufferers in power ache who’ve tried different approaches.

Extra lately, researchers around the globe started to marvel if these implants may very well be modified in order that quite than block nerve messages, they stimulated them, to assist sufferers with damaged spinal cords regain motion.

A number of years in the past I did a TV collection the place we checked out pioneering spinal stimulation work being carried out on the College of Louisville in Kentucky.

The affected person was a 26-year-old Texan referred to as Kent who, like Michel, had damaged his again in a motorcycle accident and who was completely paralysed under the chest.

A crew, led by Dr Susan Harkema from the Kentucky Spinal Twine Damage Analysis Heart, had implanted a tool into his backbone, slightly below the harm. I had assumed that when the spinal wire has been damaged, the nerves under the break would progressively wither away.

So it was beautiful to see how a lot distinction the implant made. By stimulating the remaining nerves that they had made them extra excitable and extra aware of the faint messages nonetheless getting by way of from the mind.

It gave Kent again his bowel and bladder management, and likewise meant that he might stand, unaided, and even transfer his legs. Now two Swiss neuro scientists, Grégoire Courtine and Jocelyne Bloch, have taken this analysis a step additional, creating bigger implants that use synthetic intelligence to make sure way more exact management over the neurons that management the leg muscular tissues.

They put their specifically designed implants into three sufferers (one among them Michel Roccati), all of whom had very severe spinal accidents, and inside a day of getting their implants activated, all three have been, says Dr Courtine, ‘capable of stand, stroll, pedal and swim.’

Inside just a few months they have been additionally in a position to participate in social actions, corresponding to having a drink whereas standing at a bar.

That is nonetheless very early days however the firm, Onward Medical, who’re commercialising this analysis, inform me that they’re now planning larger trials, which can hopefully contain British sufferers, later this yr.

I’ll be following future developments with eager curiosity and hope to convey you an replace quickly.

What’s the correct quantity of sleep for a wholesome mind? You may assume extra is best, however a examine from the College of Oslo in Norway — primarily based on mind scans — means that on common you want simply 6.8 hours. The researchers discovered that individuals with the most important hippocampus (the realm of the mind important for reminiscence) have been among the many shortest sleepers, getting on common simply 6.2 hours. That’s reassuring for folks like me who wrestle to get the really useful 7-8 hours an evening.

Don’t panic! Consuming veg actually IS good for you

‘Consuming loads of veg might NOT assist keep at bay coronary heart illness’ was the stunning declare this week from researchers at Oxford College, who discovered that individuals who ate numerous cooked veg weren’t any higher off than veg dodgers.

This so flies within the face of earlier analysis I regarded on the examine to seek out out extra. The very first thing to say is that it was an impressively massive examine, involving practically 400,000 volunteers from the UK Biobank, an enormous analysis venture which, since 2006, has been serving to reply a number of vital well being questions.

Within the new examine, researchers analysed meals questionnaires these folks had stuffed in in the beginning of the examine, after which tracked down what had occurred to them 12 years later.

In addition to discovering that consuming numerous cooked veg didn’t appear to enhance coronary heart well being, the evaluation confirmed that whereas individuals who ate numerous uncooked greens have been much less more likely to die from coronary heart illness, this was largely because of different components, corresponding to earnings or way of life. So it wasn’t the uncooked veg that made the distinction however the truth that they tended to be wealthier and extra well being acutely aware.

However how do you clarify these findings about cooked veg? Tom Sanders, who’s Professor Emeritus of Vitamin and Dietetics at King’s Faculty, London, thinks this can be a case of ‘reverse causality’ — the place ‘the group consuming the best ranges of greens have been extra more likely to be receiving medicine for prime blood ldl cholesterol and hypertension’. In different phrases the ‘excessive veg group’ included folks already at larger danger of coronary heart illness and who have been consuming extra veg within the hope of stopping a coronary heart assault. If that’s the case, it’s not stunning they confirmed little profit.

And whereas the analysis didn’t present any coronary heart advantages, those that ate essentially the most veg had the bottom danger of dying prematurely from any trigger — probably as a result of consuming veg protects towards ailments corresponding to most cancers.

We all know veg comprises numerous vitamins and fibre, that are good for our general well being and our intestine micro organism.

So I’ll go on fortunately piling my plate with virtually any veg, besides Brussels sprouts.



What makes some folks extra engaging than others? This was the topic of a collection I did with John Cleese and Liz Hurley.

Some researchers advised it’s about having extra symmetrical options, which in flip is a mirrored image of how wholesome you’re; others thought it’s extra to do with the power of the opposite particular person’s immune system, which we will, apparently, unconsciously detect.

Assist for that idea comes from a latest U.S. examine, the place younger adults underwent blood assessments and photographs of them have been rated for attractiveness. Lo and behold, these thought-about extra engaging additionally had the healthiest immune system. This is sensible from an evolutionary perspective as mating with them can be more likely to produce more healthy offspring.

Folks in search of love may need to replace their courting profile to incorporate: ‘I’ve excessive ranges of pure killer cells’.
