Hubble is reprising one of its greatest hits. Twenty years after the release of its iconic image of the Eagle nebula's "Pillars of Creation", the space telescope – which turns 25 this year – has captured two new, even sharper views that peer through the pillars' shrouds of dust.

The original image, taken in 1995 with Hubble's Wide Field and Planetary Camera 2, revealed three towering "elephant trunks" of gas and dust that are in the process of forming new stars. The columns are also being sculpted and eroded by winds from nearby young star.

Scientists have zeroed in on a family of fragile molecules known as cocoa flavanols. Research suggests they can relax blood vessels, improve blood flow and, as Small found in his study, even increase activity in a part of the brain involved with age related memory loss.

But those flavanols largely disappear once the cocoa bean is heated, fermented and processed into chocolate. In other words, making chocolate destroys the very ingredient that is supposed to make it healthy.
