As different as they may seem, zebrafish have many things in common with humans - some diseases, for example. Researchers have been investigating an eye disorder in zebrafish to help develop a treatment for use in people.
Zebrafish are surprisingly similar to humans. Swiss genetics researchers are using the fish to study an eye disease that also affects humans. In what is known as spontaneous nystagmus the eye does not track moving objects, but moves in the opposite direction.
The condition can lead to vision impairment. The scientists found that in fish with the disorder the optic nerves do not cross. They hope this discovery will help lead to a treatment in humans.
An archaeologist studying a Celtic burial mound in Germany has discovered that it was not only a grave site, but a huge astronomical chronometer. The prince's grave at its center is part of a gigantic calendar. With the help of technology developed by NASA the researcher found that the arrangement of the other 130 graves in the tumulus correspond to the constellations in the northern night sky.
The Celtic lunar calendar may be proof of the astronomical sophistication of a European culture long before the Roman era.
An archaeologist studying a Celtic burial mound in Germany has discovered that it was not only a grave site, but a huge astronomical chronometer. The prince's grave at its center is part of a gigantic calendar. We ask Dr. Matteo Valleriani why archaeological findings are important for people today.
Scientists in Erlangen have managed to produce graphene in large quantities with the help of soap and ultrasound. Graphene is the thinnest material known to us. It's transparent and harder than diamond. The ultra-thin carbon layer is an excellent conductor of electricity and heat.
Its properties have opened up a whole set of new industrial applications - like the mobile phone you can wrap around your arm, or a carbon-based computer. It also offers possibilities for making stable and highly conducting plastics.
