The robot suit providing hope of a walking cure
Clothing that can help people learn how to walk again after a stroke is the brainchild of a Harvard team reinventing the way we use robot technologyConor Walsh ’s laboratory at Harvard University is not your everyday research centre. There are no bench-top centrifuges, no fume cupboards for removing noxious gases, no beakers or crucibles, no racks of test tubes and only a handful laptop computers. Instead, the place is dominated by clothing.On one side of the lab stands a group of mannequins dressed in T-shirts and black running trousers. Behind them, there are racks of sweatshirts and running shoes. On another wall of s...

Mediterranean diet 'could prevent 19,000 deaths a year in UK'
Major study of eating habits concludes diet rich in olive oil, fruits and vegetables could cut heart attack and stroke deathsThousands of deaths from heart disease and stroke could be prevented if everybody ate a Mediterranean diet, a major study of the UK ’s eating habits has shown.The health benefits of the Mediterranean diet, rich in olive oil and fruits and vegetables, are well-known, but the study is the first to look at it in the real world of the UK. Gathering data about eating habits among nearly 24,000 people in Norfolk over an average of 12 to 17 years, the researchers found that 12.5% of heart attack and strok...

Common painkillers linked to increased risk of heart failure, BMJ finds
Anti-inflammatory drugs such as ibuprofen add to dangers, particularly in the elderly, study of 10 million users concludesCommon painkillers such as ibuprofen used by millions of people in the UK are linked to an increased risk of heart failure, experts have said.Non-selective non-steroidal anti-inflammatory drugs (NSAIDs) could increase the risk of being admitted to hospital. Previous studies have linked the drugs to abnormal heart rhythm – which can cause heart failure – and an increased risk of heart attack and stroke if taken regularly.Continue reading...

How family tragedy turned Roald Dahl into a medical pioneer
After his wife ’s stroke and his daughter’s death from measles, Roald Dahl applied his genius to medicine – making extraordinary breakthroughs. His doctor and friend recalls what he learned while treating the author in the last year of his lifeIn 1990, I was a junior doctor at the John Radcliffe hospital in Oxford. I had finished all my training, and was now starting my first year on the wards.Roald Dahl was one of my patients. I can still remember the night I first met him.It was nearly midnight and the lights were low. I was working away on the ward computer when I became aware of this large figure wandering slowly...

WHO's recommended level of exercise too low to beat disease – study
Bigger reductions in risk of five common chronic diseases only achievable with five to seven times more activity, research findsHigher levels of physical activity can achieve bigger reductions in the risk of five common chronic diseases, but only if people engage in levels far above the recommended minimum exertion,a study has suggested.An analysis of 174 studies found that gardening, household chores and more strenuous activities, when done in sufficient quantities, were strongly associated with a lower risk of stroke and of contracting breast and bowel cancer,diabetes and heart disease.Continue reading...

Lab notes: welcome to the Guardian's weekly science roundup
Welcome to the first weekly roundup of the best of the Guardian’s science coverage. And what a week it’s been. Without question, the biggest story of the week has been the news that scientists in California trying to grow human organs inside pigs have successfully created part-human, part-pig embryos. Chimeras aside, we’ve also had the shocking news that air pollution is now a major contributor to stroke worldwide, and excitement as researchers discover the fossil remains of what appear to be the ancestors of the Flores ‘hobbits’. Noel Edmonds also distracted the internet with claims that an electronic box could ...

Air pollution now major contributor to stroke, global study finds
Scientists say finding is alarming, and shows that harm caused by air pollution to the lungs, heart and brain has been underestimatedAir pollution has become a major contributor to stroke for the first time, with unclean air now blamed for nearly one third of the years of healthy life lost to the condition worldwide.In an unprecedented survey of global risk factors for stroke, air pollution in the form of fine particulate matter ranked seventh in terms of its impact on healthy lifespan, while household air pollution from burning solid fuels ranked eighth. Continue reading...

If you can't imagine things, how can you learn?
We know some people can’t conjure up mental images. But we’re only beginning to understand the impact this “aphantasia” might have on their educationNever underestimate the power of visualisation. It may sound like a self-help mantra, but a growing body of evidence shows that mental imagery can accelerate learning and improve performance of all sorts of skills. For athletes and musicians, “going through the motions,” or mentally rehearsing the movements in the mind, is just as effective as physical training, and motor imagery can also help stroke patients regain function of their paralysed limbs.For most of us,...

A stroke of luck at a bleak time meant I got to take the ground-breaking Herceptin. It allowed me to live, and follow my dream of becoming an authorThough I loved being an English teacher, my dream from childhood was to be a writer. Aged 34, I was head of English in a secondary school, newly married, and about to start a family. Just three weeks after the wedding I found something strange in my right breast. It was more of a mass than a lump.On the 11 November 2004 at 1.35pm, I was told I had cancer. The words I remember were “no cure”, “mastectomy”, and “breast cancer and pregnancy don’t mix” – all said in...

The foul reign of the biological clock | Moira Weigel
It seems like the concept of the biological clock has been with us forever. In fact, the metaphor was invented in the late 1970s. And it has been used to reinforce sexist ideas ever sinceI wasted years with x!” I have never heard a straight man say this. But when a woman does, after a breakup, everyone immediately understands what she means. We are raised to believe that female bodies are time bombs. Any relationship that does not “work out” – which is to say, does not get a woman pregnant by a man committed to helping her raise their offspring – brings her closer to her expiration date. At the stroke of midnight...
