Fit elderly 'can boost longevity'
(Feb 12, 2008)

It is never too late to reap the benefits of a healthy, active lifestyle, research has concluded. Scientists found 70-year-olds who take regular exercise, eat well, and do not smoke greatly increase their chance of living until 90. The researchers estimate that longevity is only at most 30% down to our genes – the rest is down to lifestyle factors.

Deep stimulation 'boosts memory'
(Jan 30, 2008)

Electrical stimulation of areas deep within the brain could improve memory, early research suggests. A team of doctors in Canada stumbled upon the finding while attempting to treat a morbidly obese man through deep brain stimulation (DBS). The electrical stimulation caused the patient to experience vivid memories.

Sedentary life 'speeds up ageing'
(Jan 30, 2008)

Leading a sedentary lifestyle may make us genetically old before our time, a study suggests. A study of twins found those who were physically active during their leisure time appeared biologically younger than their sedentary peers. The researchers found key pieces of DNA called telomeres shortened more quickly in inactive people. It is thought that could signify faster cellular ageing.

Morning coffee is 'meal in a cup'
(Jan 27, 2008)

The coffee you grab on the way to work may contain up to a fifth of your daily recommended calories, a study says. Some of those tested by Which? topped the scales at almost 400 calories. Researchers said lashings of full-fat milk, cream and chocolate are the culprits with a skimmed milk cappuccino weighing in at fewer than 30 calories.

Who wants to live for ever?
(Jan 24, 2008)

A genetically engineered organism that lives 10 times longer than normal has been created by scientists in California. It is the greatest extension of longevity yet achieved by researchers investigating the scientific nature of ageing. If this work could ever be translated into humans, it would mean that we might one day see people living for 800 years.

Broccoli 'fights' heart disease
(Jan 22, 2008)

Eating broccoli may protect against heart disease, US research suggests. Rats were fed an extract of the vegetable for a month, and the effect on their heart muscle was measured. Compared with animals whose diet did not change, the hearts of the broccoli rats functioned better and displayed less damage when deprived of oxygen.

Sunday 'worst sleep' of the week
(Jan 22, 2008)

Sunday is the hardest night of the week to get a good, undisturbed sleep, research suggests. The study of 3,500 adults, commissioned by the hotel chain Travelodge, found nearly 60% of workers have their worst night's sleep on a Sunday. More than a quarter of those surveyed admitted to calling in sick on Monday after having a dreadful night's sleep.

Scientists unveil 'supercarrot'
(Jan 18, 2008)

Scientists in the US say they have created a genetically-engineered carrot that provides extra calcium. They hope that adding the vegetable to a normal diet could help ward off conditions such as brittle bone disease and osteoporosis. Someone eating the new carrot absorbs 41% more calcium than if they ate the old, the Proceedings of the National Academy of Sciences study suggests.

'Spare part heart' beats in lab
(Jan 14, 2008)

The stripped-out shell of a heart has been made to work again – using brand new cells planted inside it. Scientists removed all the muscle cells in a rat heart, leaving just a "scaffold" of other tissues such as blood vessels and valves. When the University of Minnesota team added heart cells, they quickly grew and produced a pumping action.

Healthy living 'can add 14 years'
(Jan 8, 2008)

Taking exercise, drinking moderately, eating sufficient fruit and vegetables and not smoking can add as much as 14 years to your life, a study has found. Research involving 20,000 people over a decade found those who failed on all criteria were four times more likely to have died than those who succeeded.

Super-wine might boost lifespan
(Jan 7, 2008)

Would you drink wine made from genetically engineered grapes if it had extra benefits? Such wine could be on the menu, thanks to a grape variety six times richer than normal in resveratrol, the compound in red wine associated with increased longevity, decreased heart disease and a host of other benefits.
