Biodiversity goes digital. Scientists are working on a database of the earth's organisms, with genetic information about all the planet's animals and plants. It could be of great use to scientists - and to border police.
An international consortium of scientists is pushing for a database of all the earth's species. They are using DNA barcodes, designed to make the identification of species faster and more accurate than ever before.
Scientists around the world have been charged with collating the genetic data of all the insects, birds, animals and plants found in their countries. Our report visits a German scientist who is involved in compiling this vast inventory of life. The applications of the database, once complete, will range from conservation to pest control or even helping customs officials fight the illegal trade in animals.
The E-ELT, or European Extremely Large Telescope, is set to be the world's most powerful telescope ever. It's a project of the European Southern Observatory. It's not due to go into operation for about another decade, but the sense of anticipation is already growing.
We take a look at how "the worlds biggest eye on the sky" is coming along. One area that the E-ELT will be focusing on is the mystery of black holes. It will investigate for the first time the closer vicinity around the supermassive black hole at the center of our galaxy. We ask what scientists are hoping to discover and how fundamental their discoveries could be.
Professor Dieter Breitschwerdt will join us in the studio to discuss the telescope further. He heads up the Center for Astronomy and Astrophysics at Berlin's Technical University.
There are various different ways for relieving stress. Tobias Esch from the Coburg University of Applied Scientists has been researching meditation as a relaxation technique and the effect that it has on the body.
He discovered that at the start of meditation, the body surprisingly releases stimulating neurotransmitters like dopamine and noradrenalin. Esch believes this is perhaps part of the body's natural survival instinct. Only once it becomes clear that this is a safe time and place to relax are other neurotransmitters released which counteract the stress hormones, resulting in genuine relaxation.
Coronary angiography involves passing a guide wire through a blood vessel into the heart. It provides doctors with important information and is used for a range of preventive treatments.
The procedure is painless - yet it is fraught with anxiety for many patients. Music psychologists have discovered that certain kinds of music can provide help here. Studies show that patients are considerably less anxious when the music is played during surgery.
