Scientists have a new recipe for batteries: Bake a leaf, add sodium. They used a carbonized oak leaf, pumped full of sodium, as a demonstration battery’s anode. Other studies have shown that melon skin, banana peels and peat moss can be used in this way, but a leaf needs less preparation. The scientists are trying to make a battery using sodium where most rechargeable batteries sold today use lithium. Sodium would hold more charge, but can’t handle as many charge-and-discharge cycles as Li can.

One of the roadblocks has been finding an anode material that is compatible with sodium, which is slightly larger than lithium...

Doctors have shown the benefits of a healthy diet and exercise in patients with heart failure. The annual congress of the Mexican Society of Cardiology is being held in Acapulco from 21 to 25 November 2015. Experts from the European Society of Cardiology (ESC) will present a special programme

In Mexico there are 750,000 patients living with heart failure and the problem is growing. It is estimated that 75,000 more patients will get heart failure each year. “Just 25% of men and 38% of women with heart failure in Mexico will be alive after 5 years,” said Dr Arturo Orea...
