Biomedicine professor Mark Post predicts that we will soon be growing steaks in labs. He's already produced the first ever burger from stem cells. He says culturing meat is far more environmentally friendly than keeping and killing livestock.

The Viennese food scientist Hanni Rützler examines this question. Her thesis is that food production should not be understood as big business if everyone on earth is to have enough to eat.Instead, traditional and new forms of agriculture should co-exist - fields on the one hand, urban farming on the other. And how about insects as an alternative source of protein? How realistic are these expectations? DW’s Maria Lesser spoke to Hanni Rützler.

Dutch researcher mark Post is convinced that in future, steaks could be lab-grown. The biomedicine professor at the University of Maastricht is a specialist in tissue culture. He is convinced that using stem cells, beef and pork could be grown in labs. Just like is being done for medical purposes. In 2013, Post already succeeded in artificially growing the first ever burger patty. It cost 250,000 Euros to make. Post reckons that cultured meat from stem cells will soon become mainstream...

Practically all species of rhino around the world are now endangered, their numbers depleted by poachers who then sell their horns on the lucrative black market. Demand is especially high in China and Vietnam, where rhino horns are used for medicinal purposes. A biotech team in the US, however, is now making bioengineered replicas of horns with a 3D printer that are visually and genetically identical to the real thing...

Most species of rhino have been decimated by poachers, who sell their horns on the lucrative black market. Researchers want to put them out of business with cut-price artificial replicas. Will the idea help the animals?

Cancer researchers in Bonn are using high-energy sound waves to destroy tumors. The therapy holds promise for patients where surgery would be too risky. When high-intensity sound waves are focused similar to the way that a magnifying glass focuses the rays of the sun, the sound waves can generate intense heat that destroys tumor cells. If this high-frequency focused ultrasound therapy proves successful, it may be a way to help patients with inoperable tumors.

Cancer researchers in Bonn are testing a new therapy to treat cancers that are inoperable, for example because they have spread to vital organs. The therapy involves ultrasound, which is more familiar in diagnostic procedures. When high-intensity sound waves are focused similar to the way that a magnifying glass focuses the rays of the sun, the sound waves can generate intense heat that destroys tumor cells...

Can trauma be healed? Is it hereditary? Malek Bajbouj is a psychiatrist and neurologist at the Charité Hospital in Berlin. He works with traumatized patients from Arabic-speaking countries in a specially created outpatient clinic.Many refugees come to him and he is collaborating with fellow-doctors in Jordan. A few years ago, he set up a project in Syria offering psychological help to people traumatized by war. DW visits the therapist to find out how science can help overcome trauma.

Researchers at Germany's Fraunhofer Institute for Industrial Engineering are working to develop the lighting systems of the future. These systems will be able to adjust themselves to people's daily rhythms -- both at home, and at the office. Light regulates our biological clock, determines when we sleep and wake up, and influences heart rate and blood pressure.Blue light is particularly important. During the day, it makes people more active because it suppresses the sleep hormone melatonin...
