AI makes non-invasive mind-reading possible by turning thoughts into text
Advance raises prospect of new ways to restore speech in those struggling to communicate due to stroke or motor neurone diseaseAn AI-based decoder that can translate brain activity into a continuous stream of text has been developed, in a breakthrough that allows a person ’s thoughts to be read non-invasively for the first time.The decoder could reconstruct speech with uncanny accuracy while people listened to a story – or even silently imagined one – using only fMRI scan data.Previous language decoding systems have required surgical implants, and the latest advance raises the prospect of new ways to restore speech i...

MRI scan that can predict stroke risk has 'promise to save lives'
Scientists at Oxford University develop non-invasive technique to measure amount of cholesterol in carotid plaquesA new type of MRI scan can predict the risk of having astroke, researchers have said in a study.The non-invasive technique, developed by scientists at the University of Oxford, predicts whether plaques in the carotid arteries are rich in cholesterol and therefore more likely to cause a stroke.Continue reading...

Lab notes: what a mammoth week for science!
Yes it ’s a big story in more ways than one – a team of Harvard scientists say that scientists say they are on thebrink of being able to create a hybrid elephant-mammoth embryo. There are lots of technical and ethical concerns to address before we actually have real, live mammoths (or mammophants, as they ’re being called by some) but the idea of “de-extinctifying” something that’s been gone for 4,000 years is pretty exciting. This isn’t the only genetic engineering story in town this week, though, as amajor US report out this week has prepared ground for genetic modification of human embryos, eggs and sperm ...

Portable brain-scanning helmet could be future for rapid brain injury assessments
Stroke victims and those felled by head injuries on the sports pitch or battlefield could benefit from a new wearable scanner currently being testedA transportable brain-scanning helmet that could be used for rapid brain injury assessments of stroke victims and those felled on the sports pitch or battlefield is being tested by US scientists.The wearable device, known as the PET helmet, is a miniaturised version of the hospital positron emission tomography (PET) scanner, a doughnut-shaped machine which occupies the volume of a small room.Continue reading...

Inside the mummies' embalmed bodies courtesy of a hospital CT scanner
The British Museum's next big exhibition reveals secrets that experts have been able only to guess at until nowSpare a thought for the unknown adult mummified in a Theban necropolis more than 2,500 years go. Not only did he suffer the most excruciating, possibly life-threatening dental abscesses, but the embalmer botched the afterlife preparation, leaving bits of brain in his skull as well as a broken section of the spatula he was using to remove it.Then there's Tamut, a temple singer with enough calcified plaque in her arteries to risk a heart attack or stroke.

Do No Harm: Stories of Life, Death and Brain Surgery review
Patients see neurosurgeons as gods, but what is the reality? Henry Marsh has written a memoir of startling candourWe go to doctors for help and healing; we don't expect them to make us worse. Most people know the aphorism taught to medical students, attributed to the ancient Greek Hippocrates but timeless in its quiet sanity: "First, do no harm." But many medical treatments do cause harm: learning how to navigate the risks of drug therapies, as well as the catastrophic consequences of botched or inadvised surgical operations, is a big part of why training doctors takes so long. Even the simplest of therapies carries the ri...

A safe, effective diet pill - the elusive holy grail
Trade in illegal, ineffective drugs flourishes as pharmaceutical industry repeatedly fails to produce successful pillAttempts to invent a safe and effective diet pill have foundered time and again, allowing the internet trade in illegal and ineffective herbal supplements and dangerous drugs, such as DNP, to flourish.A successful diet pill could make billions for the pharmaceutical industry, but efforts to date have ended in disaster, with patients harmed, drugs banned and massive compensation paid out.Fen-phen, an appetite suppressant, was the most spectacular failure. It was withdrawn in the US in 1997 after causing wides...

Stargazing Live | Death In Paradise | The Undateables | Primeval: New World | Taboo | PramfaceStargazing Live8pm, BBC2In what looks like it will be an annual fixture, Professor Brian Cox scans the night skies with that infectiously awestruck, half-moon smile of his. He's accompanied once more by comedian Dara Ó Briain, who makes for an effective sidekick with his comic rather than cosmic background and demeanour. He is shown how to spot and take pictures of celestial marvels, followed by half an hour of discussion with an invited audience over what hidden glories the telescope has revealed.

Should Hillary Clinton be back at work so soon after a blood clot?
A doctor on whether the US secretary of state should be taking it easy after her health scareHillary Clinton is back at work today with 12 meetings scheduled this week, just four weeks after a blood clot on the brain. What advice would I give her if she pitched up at my GP surgery in north London?Her problems apparently kicked off at the beginning of December with a nasty European tummy bug. She became so dehydrated that she fainted and banged her head. She was admitted to hospital on 30 December and diagnosed with a right transverse venous sinus thrombosis (a blood clot in the large vein that runs in the space between bra...
