Ultra-processed food raises risk of heart attack and stroke, two studies show
Research presented to annual meeting of European Society of Cardiology prompts calls for actionUltra-processed food significantly raises the risk of high blood pressure, heart disease, heart attacks and strokes, according to two studies that one expert says should serve as a wake-up call for governments worldwide.Global consumption of heavily processed items such as cereals, protein bars, fizzy drinks, ready meals and fast food has soared in recent years. In the UK and US, well over half the average diet now consists of ultra-processed food (UPF). For some, especially people who are younger, poorer or from disadvantaged ar...

Salt-free diet ‘can reduce risk of heart problems by almost 20%’
Large new study using UK Biobank data shows even a small reduction in salt intake can be beneficialCutting out salt from meals can slash your risk of heart problems and strokes by almost a fifth, the largest study of its kind suggests.Research has documented how adding salt to food increases the likelihood of cardiovascular disease and premature death. Now experts have established just how big a difference you could make to your heart health – simply by reducing the number of meals to which you add salt or by ditching it altogether.Continue reading...

Paralysed woman able to ‘speak’ through digital avatar in world first
Latest technology uses tiny electrodes on brain surface and is faster than synthesisers which rely on eye trackingA severely paralysed woman has been able to speak through an avatar using technology that translated her brain signals into speech and facial expressions.The advance raises hopes that brain-computer-interfaces (BCIs) could be on the brink of transforming the lives of people who have lost the ability to speak due to conditions such as strokes and amyotrophic lateral sclerosis (ALS).Continue reading...

Scientists reconstruct Pink Floyd song by listening to people ’s brainwaves
Breakthrough raises hopes that musicality of natural speech can be restored in patients with disabling neurological conditionsScientists have reconstructed Pink Floyd ’s Another Brick in the Wall by eavesdropping on people’s brainwaves – the first time a recognisable song has been decoded from recordings of electrical brain activity.The hope is that doing so could ultimately help to restore the musicality of natural speech in patients who struggle to communicate because of disabling neurological conditions such as stroke or amyotrophic lateral sclerosis – the neurodegenerative disease that Stephen Hawking was diagn...

People who cram week ’s exercise into two days still reap heart benefits – study
‘Weekend warriors’ have similarly low risk of heart disease and stroke as those who spread out their physical activityPeople who fit an entire week ’s recommended exercise into a couple of days have a similarly low risk of heart disease and stroke as those who spread out their physical activity, researchers say.The results from a major study on “weekend warriors” against more regular exercisers suggest that even when people are too busy to exercise in the working week, making up for the inactivity at the weekend can still improve cardiovascular health.Continue reading...

Vitamin D supplements may cut risk of heart attacks, trial suggests
The largest study of its kind may prove a link between vitamin D levels and the risk of cardiovascular diseaseVitamin D supplements may cut the risk of serious cardiovascular events such as heart attacks in older people, according to the largest study of its kind.Cardiovascular disease (CVD) is one of the main causes of death globally. The number of cardiovascular events is predicted to surge as populations continue to age and chronic diseases become more common.Continue reading...

Supermarket trolley sensors could help to identify risk of stroke, say scientists
Study with 2,155 participants at Sainsbury ’s stores leads to atrial fibrillation diagnosis for 39 people unaware they had conditionSupermarket trolleys may be known for their wonky wheels and rusty frames, but researchers say the carts could be used to save lives by helping to identify people at risk of stroke through sensors in their handles.According to the British Heart Foundation, one in 45 people in the UK are living with atrial fibrillation (AF), which causes an abnormal heart rhythm and can increase the risk of stroke. While people may be unaware they have the condition, early detection and diagnosis is important...

A measurement for chronic pain is a scientific holy grail – and we’re getting closer | Abdul-Ghaaliq Lalkhen
People who have chronic pain without a visible injury are often not believed, but new research can help visualise that painMost people, including doctors, do not appreciate that the organ that produces pain is the brain. A broken bone, damaged tissue or a bleeding wound is often the focus, but the experience of pain is the sum total of more than just the physical injury – it is the result of information sent from our nerves being filtered through an individual’s unique psychological makeup, genetics, gender, beliefs, expectations, motivations and emotional context. Pain is therefore an individual experience, and often ...

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...

Are coincidences real?
The rationalist in me knows that coincidences are inevitable, mundane, meaningless. But I can ’t deny there is something strange and magical in them, tooIn the summer of 2021, I experienced a cluster of coincidences, some of which had a distinctly supernatural feel. Here ’s how it started. I keep a journal, and record dreams if they are especially vivid or strange. It doesn’t happen often, but I logged one in which my mother’s oldest friend, a woman called Rose, made an appearance to tell me that she (Rose) had just died. She had had another stroke, she said, and that was it. Come the morning, it occurred to me tha...
