Healthy lifestyle helps body's cells fight ageing: Scientists

Scientists says strategy is structured around a whole-food‚ plant-based diet‚ moderate daily exercise‚ yoga-based relaxation.

Scientists said that they had proof

 that a healthy lifestyle helps the 

body's cells fight ageing.

They said that the strategy is 

structured around a whole-food‚

 plant-based diet‚ moderate daily

 exercise‚ yoga-based relaxation

 and stress management.

The researcher said that the 

implications of this relatively 

small pilot study may go beyond 

men with prostate cancer.

If validated by large-scale 

randomized controlled trials‚ these comprehensive lifestyle changes may significantly reduce the

 risk of a wide variety of diseases and premature mortality.

Sleep boosts brain cell numbers

Sleep boosts brain cell numbers

In contrast‚ the genes involved in cell death and stress 

responses were turned on when the mice were forced to 

stay awake.

Scientists believe that

 they have discovered 

a new reason why we 

need to sleep it replenishes

 a type of brain cell.

Dr Chiara Cirelli and 

colleagues from the 

University of Wisconsin

 found that the production

 rate of the myelin making

 cells‚ immature 

oligodendrocytes‚ doubled

 as mice slept.

The increase was most marked during the type of sleep that is associated with 

dreaming - REM or rapid eye movement sleep - and was driven by genes.

In contrast‚ the genes involved in cell death and stress responses were turned on when the

 mice were forced to stay awake.

Dr Cirelli said that for a long time‚ sleep researchers focused on how the activity of nerve 

cells differs when animals are awake versus when they are asleep.

Sleep loss can make you fat: Study

Sleep loss can make you fat: Study

Researchers have long pointed to a correlation between a 

steep rise in obesity in industrialized nations and a decline in 

sleep duration.

Scientists had found evidence

 that a lack of sleep causes 

changes in brain activity that 

lead to people feeling hungrier

 and craving more fattening

 foods.

Researchers have long pointed

 to a correlation between a

 steep rise in obesity in

 industrialized nations and a

 decline in sleep duration.

A causal link was suspected‚

 but science has not been able to explain the mechanism‚ until now.

A team from the University of California said they used MRI (magnetic resonance imaging)

 scans to spot changes in the brain activity of sleep-deprived test subjects.

Researchers said these findings provide an explanatory brain mechanism by which

 insufficient sleep may lead to the development/maintenance of obesity.

Scientists find clue to age-related memory loss

Scientists find clue to age-related memory loss

Experiments on mice suggested low levels of a protein in the brain 

may be responsible for memory loss.

A clue to why memory deteriorates with age has been found by US

 researchers.

Experiments on mice suggested low levels of a protein in the brain 

may be responsible for memory loss.

It is hoped the discovery could lead to treatments to reverse 

forgetfulness‚ but it is a big leap from the mouse to a human brain.

The team at Columbia University Medical Centre started by analysing 

the brains of eight dead people‚ aged between 22 and 88‚ who had 

donated their organ for medical research.

Thirsty work: drinking water can improve reaction times

Thirsty work: drinking water can improve reaction times

Around 80 percent of the brain is water‚ so it is clearly important 

to make sure it gets enough.

Scientists have found that the Quenching your thirst during the hot weather with a glass of water 

can help make your brain work faster.

Published in the journal Frontiers in Human Neuroscience discovered that people who drank a pint

 of water before conducing mental tasks had reaction times that were 14% faster than those who did 

not have drink.

Dr Caroline Edmonds a psychologist said that Reaction time seemed to be most affected by water‚ 

particularly if the people were thirsty.

Around 80 percent of the brain is water‚ so it is clearly important to make sure it gets enough.
