Lifestyle changes might guard against dementia

Lifestyle changes might guard against dementia

Seek a good education. Control blood pressure and diabetes. Get off the couch. There are some hints, but no proof yet, that these and other lifestyle changes just might help stave off dementia. A provocative report in the British journal Lancet Thursday raised the prospect that a third of dementia cases around the world could be delayed or even prevented by avoiding key risks starting in childhood that can make the brain more vulnerable to memory loss in old age….

Yoga and Meditation can change your genes, study shows

Yoga and Meditation can change your genes, study shows

Yoga and meditation may do more than just help you feel relaxed in the moment. A new scientific review suggests that these and other mindfulness exercises can actually reverse stress-related changes in genes linked to poor health and depression. In the new paper, published in Frontiers in Immunology, British researchers analyzed the findings from 18 previously published studies—involving a total of 846 people—on the biological effects of meditation, yoga, breathing exercises, Qi gong and Tai Chi. Together, the authors say,…

Dying is a happier experience than most people imagine

Dying is a happier experience than most people imagine

Dying is a more positive experience than most people imagine, psychologists have claimed. A recent YouGov survey found 68 per cent of people in Britain fear death – but according to the authors of new study, dying is “less sad and terrifying – and happier – than you think”. Researchers at the University of North Carolina analysed blogs written by terminally ill patients and last words of prisoners on death row.

This new gene therapy could help ‘turn-off’ asthma!

This new gene therapy could help ‘turn-off’ asthma!

Sydney: A new gene therapy has been developed by a team of researchers that could help to ‘turn-off’ the immune response which causes allergic reaction such as asthma, or potentially lethal food allergies. Ray Steptoe, Associate Professor at the University of Queensland in Australia said,”When someone has an allergy or asthma flare-up, the symptoms they experience results from immune cells reacting to protein in the allergen.” The study showed that the single treatment may give life-long protection from asthma as…

How one death saved seven lives

How one death saved seven lives

A seven-year-old boy’s heart has finally stopped beating 22 years after he was shot dead. Nicholas Green, from the US, was killed during a holiday in southern Italy in 1994 when attackers mistook his family’s rental car for one involved in a jewellery heist. His brave parents opted to donate their son’s organs and his heart, corneas, kidneys, liver and pancreas were given to seven people in desperate need – changing their lives forever.

The Woman with a strange “second sight”

The Woman with a strange “second sight”

It ranks among the most curious phenomena in cognitive neuroscience. A handful of people in the world have “blindsight”: they are blind, but their non-conscious brain can still sense their surroundings. Milina Cunning, from Wishaw in Scotland, lost her sight in her 20s, and later realised she had this blindsight ability. She has been studied extensively by researchers. “If I was to throw a ping pong ball at Milina’s head, she would probably raise her arm and duck out of…

Fear of talking about dying ‘leading to thousands of traumatic hospital deaths’

Fear of talking about dying ‘leading to thousands of traumatic hospital deaths’

Thousands of cancer patients would prefer to die at home but are forced to suffer “traumatic” deaths in hospital, according to Macmillan. Taboos around talking about death are fuelling a “crisis of communication” in the UK that prevents people from planning their final days, warned the organisation in a new report. Research by the charity found that while 38 per cent of people who die from cancer die in hospital, just one per cent would choose to do so, with…

45 minutes’ exercise a week boosts brain power in over-fifties

45 minutes’ exercise a week boosts brain power in over-fifties

Just 45 minutes of exercise a week boosts the brain power of people in their fifties and over, major new research has revealed. A review of dozens of previous studies found that even one session of moderate aerobic and resistance activity is enough to enhance people’s alertness, decision-making and memory. Scientists have long believed that exercising slows down the cognitive decline that occurs naturally as people move from middle to old age, however the new analysis is the first of…

How stress causes heart attacks and strokes

How stress causes heart attacks and strokes

The reason why stress causes heart attacks and strokes may finally have been discovered by scientists, leading to hopes that it could be prevented. For years experts have puzzled as to how chronic anxiety leads to heart problems. But now scientists have found that people who have heightened activity in a part of the brain linked to stress – the amygdala – are more likely to develop cardiovascular events.

Aging may be reversible, according to scientists

Aging may be reversible, according to scientists

Getting old may not be inevitable — scientists have found a way to turn back the clock on human and animal cells, making them look and behave like younger versions of themselves. The researchers also used the method to treat mice with a rare disease that causes them to age prematurely and die early, and found that the method increased the animals’ lifespan by 30 percent. And, when normal mice received the treatment, they appeared to be rejuvenated, with some of…
