"Double Whammy"

A new study shows that being overweight doubles the effect of alcohol on the liver, substantially increasing the likelihood of contracting diseases like cirrhosis.

A new study shows that being overweight doubles the effect of alcohol on the liver, substantially increasing the likelihood of contracting diseases like cirrhosis. "Two studies of more than a million UK men and women suggest excess weight and alcohol act together to raise the risk of cirrhosis and other liver diseases. Obese women who drink little more than a glass of wine a day have almost double the risk of liver disease than other women, the researchers said.


A similar effect is seen in men, the British Medical Journal reported. The authors of the research said 'safe' alcohol limits for the overweight may need to be redefined. Rates of liver disease and obesity are increasing in the UK. Alcohol is a major cause of liver cirrhosis and there is mounting evidence that excess weight also plays a role. In the first study, researchers at the University of Oxford studied more than a million middle-aged women in England and Wales. They found that being overweight or obese increased the likelihood of developing liver cirrhosis. Obese men who said they drank 15 or more units a week had the greatest risk of liver disease; almost 19 times higher than those who were slim."

'Upstreamism': Your zip code affects your health as much as genetics

Upstreamism advocate Rishi Manchanda calls us to understand health not as a "personal responsibility" but a "common good."

  • Upstreamism tasks health care professionals to combat unhealthy social and cultural influences that exist outside — or upstream — of medical facilities.
  • Patients from low-income neighborhoods are most at risk of negative health impacts.
  • Thankfully, health care professionals are not alone. Upstreamism is increasingly part of our cultural consciousness.

Meet the Bajau sea nomads — they can reportedly hold their breath for 13 minutes

The Bajau people's nomadic lifestyle has given them remarkable adaptions, enabling them to stay underwater for unbelievable periods of time. Their lifestyle, however, is quickly disappearing.

  • The Bajau people travel in small flotillas throughout the Phillipines, Malaysia, and Indonesia, hunting fish underwater for food.
  • Over the years, practicing this lifestyle has given the Bajau unique adaptations to swimming underwater. Many find it straightforward to dive up to 13 minutes 200 feet below the surface of the ocean.
  • Unfortunately, many disparate factors are erasing the traditional Bajau way of life.

Surprising Science
  • Fewer than 50 people worldwide have 'golden blood' — or Rh-null.
  • Blood is considered Rh-null if it lacks all of the 61 possible antigens in the Rh system.
  • It's also very dangerous to live with this blood type, as so few people have it.
