Saturn Moon Has Necessary Conditions to Harbor Life

An ice-encrusted moon orbiting Saturn appears to have the conditions necessary for life, NASA announced on April 13, unveiling new findings made by its unmanned Cassini spacecraft. Cassini has detected hydrogen molecules in vapor plumes emanating from cracks in the surface of Enceladus, a small ocean moon coated in a thick layer of ice, the US space agency said. The plumes have led scientists to infer that hydrothermal chemical reactions between the moon's rocky core and its ocean -- located under the ice crust -- are likely occurring on Enceladus. On Earth, those chemical reactions allow microbes to flourish in hot cracks in the planet's ocean floors -- depths sunlight cannot reach -- meaning the Saturn moon could also nourish life. The new research appeared in the journal Science.

High Sugar Tax Can Reduce India’s Diabetes Burden

A new research published in the British Medical Journal (BMJ) shows that a 20 percent tax on sugary drinks in India can reduce the prevalence of overweight people and obesity by 3 percent, and incidence of Type 2 diabetes by 1.6 percent in the next 10 years. This assumes significance, given that the diabetes burden in India has doubled in the last 10 years from 32 million to 63 million and is projected to grow to 101.2 million in the next 15 years. The study suggests a higher tax can avert at least 400,000 cardiac deaths. Similarly, the prevalence of obesity is also as high as 22 percent among adults as well as children in India. Hypertension is also fast growing in India with a prevalence rate of 25.4 percent among adults.

Obese and Underweight Women More Likely to Get Migraine

Migraine is a headache of varying intensity, often accompanied by nausea and sensitivity to light and sound. Young women who are obese or underweight may be at an increased risk of getting migraine, claims a study. The study revealed that people who are obese (defined as a body mass index or BMI of 30 or higher) were 27 percent more likely to have migraine than people of normal weight. On the other hand, people who were underweight (defined as a BMI of less than 18.5) were 13 percent more likely to have migraine than people of normal weight, said lead author B. Lee Peterlin, from Johns Hopkins University School of Medicine. The study has been detailed in the journal Neurology.
