The quest to find new ways to harness solar power has taken a step forward after researchers successfully split water into hydrogen and oxygen by altering the photosynthetic machinery in plants.

Photosynthesis is the process plants use to convert sunlight into energy. Oxygen is produced as by-product of photosynthesis when the water absorbed by plants is ‘split’. It is one of the most important reactions on the planet because it is the source of nearly all of the world’s oxygen. Hydrogen which is produced when the water is split could potentially be a green and unlimited source of renewable energy.

A new study, led by academics at St John’s College, University of Cambridge, used semi-artificial photosynthesis to explore new ways to produce and store solar energy. They used natural sunlight to convert water into hydrogen and oxygen using a mixture of biological components and manmade technologies.

It’s the year 2038. The word “flavor” has fallen into disuse. Sugar is the new cigarettes, and we have managed to replace salt with healthy plants. We live in a society in which we eat fruit grown using genetics. We drink synthetic wine, scramble eggs that do not come from chickens, grill meat that was not taken from animals, and roast fish that never saw the sea… Here’s a futurist outlook at the next two decades of food developments, from robot farmers to 3D-printed meals to AI monitoring of your daily calorie intake.

Researchers from the University of Cambridge developed the technique, which involves splitting water into oxygen and hydrogen in plants.

Nearly a century after its founding, physicists and philosophers still don’t know—but they’re working on it.

A new study by an international team of researchers, led by scientists from the University of Bristol, has revealed the origins and evolution of animal body plans.

Animals evolved from unicellular ancestors, diversifying into thirty or forty distinct anatomical designs. When and how these designs emerged has been the focus of debate, both on the speed of evolutionary change, and the mechanisms by which fundamental evolutionary change occurs.

Did animal body plans emerge over eons of gradual evolutionary change, as Darwin suggested, or did these designs emerge in an explosive diversification episode during the Cambrian Period, about half a billion years ago?

Children born through IVF are six times more likely to suffer high blood pressure than naturally conceived children, putting them at greater risk of heart attacks and strokes, new research suggests.

In a study of 96 youngsters, researchers in the Switzerland found one in seven teenagers who were born through assisted reproduction had clinically high blood pressure by the age of 16, compared with just 2.3 per cent of those born naturally.

Around 20,000 babies are born through IVF in Britain each year. But the oldest test-tube baby — Louise Brown — is only 40 years old, so the long term impact of fertility treatment is still unknown.
