New discovery may explain winter weight gain

We may have a new reason, in addition to vitamin D generation, to bask in a little sunshine.

A breakthrough study researchers has shown the fat cells that lie just beneath our skin shrink when exposed to the blue light emitted by the sun, according to Science Daily.

"When the sun's blue light wavelengths -- the light we can see with our eye -- penetrate our skin and reach the fat cells just beneath, lipid droplets reduce in size and are released out of the cell. In other words, our cells don't store as much fat," said Peter Light, senior author of the study, who is a professor .

Prolonged periods of sedentary time strongly associated with amount of fat around internal organs

A team of researchers has found new evidence to suggest that longer periods of sedentary time (defined as any sitting/reclining activity with low energy expenditure) are more strongly associated with the amount of fat deposited around internal organs, according to Science Daily.

The study, Obesity took 124 participants at high risk of type 2 diabetes and measured the length of time they spent sedentary over a period of 7 days using accelerometers fitted to their waist. The research team also scanned the participants using magnetic resonance imaging (MRI) equipment to accurately measure the amount of fat in the liver, inner (visceral) and outer (subcutaneous) fat layers, and total abdominal fat.

Even when accounting for age, and physical activity levels, the study team found that the longer a person remained sedentary during the day, the higher the levels of liver fat, inner (visceral) fat and total abdominal fat.

Virus could treat brain cancer and boost immune system

Patients with aggressive brain tumours could be treated with a virus, according to a new study. Injected directly into the bloodstream, the virus could also boost their immune system in the process.

Scientists at the University of Leeds and the Institute of Cancer Research in London carried out successful trials on nine brain cancer patients using a ‘reovirus’. The researchers found the virus could cross the protective membrane surrounding the brain to reach tumours, according to RT.

You DO burn more calories in the cold

You really can shiver off the calories this winter, according to personal trainers and  exercise physiologists, according to Daily Mail. 

The body's primary goal is to maintain stasis, or stability, and that includes keeping a steady temperature. 

So, in the cold, the body needs to burn extra fat, to produce energy to heat it back up to the ideal temperature. 

But there's a trick to it, and personal trainer Max Zeumer spoke about his surprisingly fun tips for how to optimize your cold weather workout.

Heart attack care dangerously unequal for women

Fewer women who suffer a heart attack would die if they were given the same treatments as men, a new study found.

Researchers analysed the outcomes of 180,368 Swedish patients who suffered a heart attack over a 10-year period, according to BBC.

They found women were three times more likely to die from their heart attack than men in the year after having one.

The British Heart Foundation said: "Heart attacks are often seen as a male health issue, but more women die from heart disease than breast cancer."
