Antioxidant benefits of sleep

 Understanding sleep has become increasingly important in modern society, where chronic loss of sleep has become rampant and pervasive. As evidence mounts for a correlation between lack of sleep and negative health effects, the core function of sleep remains a mystery. But in a new study, Vanessa Hill, Mimi Shirasu-Hiza and colleagues at Columbia University, New York, found that short-sleeping fruit fly mutants shared the common defect of sensitivity to acute oxidative stress, and thus that sleep supports antioxidant processes. Understanding this ancient bi-directional relationship between sleep and oxidative stress in the humble fruit fly could provide much-needed insight into modern human diseases such as sleep disorders and neurodegenerative diseases, according to Science Daily.

An orange a day keeps macular degeneration away: 15-year study

A new study has shown that people who regularly eat oranges are less likely to develop macular degeneration than people who do not eat oranges, according to Science Daily.

Researchers at the Westmead Institute for Medical Research interviewed more than 2,000 adults aged over 50 and followed them over a 15-year period.

The research showed that people who ate at least one serving of oranges every day had more than a 60% reduced risk of developing late macular degeneration 15 years later.

Children are more likely to become snorers if they are exposed to second-hand smoke, finds study

Children exposed to second-hand tobacco smoke may become snorers, scientists claim.

An analysis of existing research suggests their risk of becoming snorers rises by up to 87 per cent, if regularly exposed to lingering cigarette smoke, according to Daily Mail.

The odds of youngsters going on to become snorers rose by around two per cent for every cigarette smoked daily in the home.

Chinese scientists reviewed 24 studies that included nearly 88,000 children to come to the conclusion.

Give your bones a workout, public told

Too many of us are neglecting to do exercises for strong muscles and bones, says Public Health England (PHE).
It's launched a new report giving advice on how people can age better by doing the right workouts.
While the message about doing aerobic exercise for a healthy heart and lungs is getting through, people are less clear about the need to look after their overall strength too, it says.

Espresso replaces insulin in potentially groundbreaking diabetes treatment

Scientists have found a rather humdrum, but still rather miraculous, way for diabetics to keep insulin in check – a good old-fashioned cup of coffee.

A team led by Biotechnologist Martin Fussenegger at the Swiss Federal Institute of Technology believes it has developed an insulin substitute that can be activated by caffeine, according to RT.

“You could completely integrate this into your lifestyle,” Fussenegger said in a statement cited by New Scientist. “You have a tea or coffee in the morning, another after lunch, and another at dinner, depending on how much drug you need to get your glucose back down.”
