Why does my body need zinc?

Zinc is one of several metals the body uses to build proteins and to help enzymes perform necessary reactions. Zinc is useful because of its chemical flexibility. It has the ability to bind in many different types of conformations, which is essential for building proteins that come in many different shapes and sizes. It can also help drive reactions by smoothing and speeding up chemical transformation. Because it often performs in a reusable situation, we don’t need large amounts of zinc in our diet.

Body's 'chemical calendar' discovered

The way the body can track the passing of the seasons in a "chemical calendar" has been discovered by scientists.

The team, found a cluster of thousands of cells that could exist in either a "summer" or "winter" state.

Hope for faster treatment of urinary tract infections

Urinary tract infections can be treated more quickly using a new DNA sequencing device, according to research.

Scientists from the University of East Anglia (UEA) say the device - the size of a USB stick - can detect bacteria directly from urine samples four times more quickly than traditional methods.

The technology could lead to faster treatment and better use of antibiotics, they say, according to BBC.
