Detection Of Two Titanium Oxides Discovered Around The Giant Star VY Canis Majoris
2013-03-27 09:17:50

Max Planck Institute for Radio Astronomy An international team of astronomers, including researchers from the Max Planck Institute for Radio Astronomy and from the University of Cologne, discovered two titanium oxides, TiO and TiO2, at radio wavelengths using telescope arrays in the USA and in France. The detection was made in the environment of VY Canis Majoris, a giant star close to the end of its life. The discovery was made in the course of a study of a spectacular star, VY Canis...

Burmese Amber Reveals Ancient Caddisfly Fossils

The examination of insects in Burmese amber by researchers at the University of Cologne, Germany and National Museums Scotland revealed a new genus of caddisfly, which has been named Palerasnitsynus. The discovery, based on two specimens, constitute the first record of the living family Psychomyiidae in Burmese amber and the oldest known member of this family in the fossil record. Burmese amber is 100 million years old, from the Cretaceous Period, so this discovery adds to our...

By exploiting the exquisite image quality of the NASA/ESA Hubble Space Telescope and comparing two observations made ten years apart astronomers have, for the first time, managed to measure the tiny motions of several hundred young stars within the central cluster of the star-forming region NGC 3603. The team was surprised to find that the stars are moving in ways that are at odds with the current understanding of how such clusters evolve. The stars in the cluster have not "settled down" as...

BASF Plant Science and the Botanical Institute of the University of Cologne announce that they have entered a cooperation in plant biotechnology. Focus is on plant traits that increase the yield of crops like soybeans, rice, and canola and improve their tolerance to adverse environmental conditions like cold, drought or salinization. The cooperation comprises both a license and an R&D agreement, which were negotiated by PROvendis, the patent marketing company for North Rhine-Westphalia's...

Scientists in the US and Germany have discovered two of the most complex molecules ever to be found in space, and their scientific models imply that even larger molecules, such as amino acids, may also exist. Scientists from the Max Planck Institute for Radio Astronomy in Bonn, Germany, Cornell University in the US, and the University of Cologne in Germany have reported the discovery of ethyl formate and n-propyl cyanide in space. Using the IRAM 30 m telescope in Spain, the team discovered...

Mendel solved the logic of inheritance in his monastery garden with no more technology than Darwin had in his garden at Down House. So why couldn't Darwin have done it too? A Journal of Biology article* argues that Darwin's background, influences and research focus gave him a viewpoint that prevented him from interpreting the evidence that was all around him, even in his own work. Darwin's commitment to quantitative variation as the raw material of evolution meant he could not see the logic...

Astronomers have used two different telescopes simultaneously to study the violent flares from the supermassive black hole in the centre of the Milky Way. They have detected outbursts from this region, known as Sagittarius A*, which reveal material being stretched out as it orbits in the intense gravity close to the central black hole. The team of European and US astronomers used ESO's Very Large Telescope (VLT) and the Atacama Pathfinder Experiment (APEX) telescope, both in Chile, to study...

A recent study on the future of climate changes suggests that the once-green Sahara turned to desert over thousands of years rather than in an abrupt shift as previously believed. The study's lead author said that parts of the Sahara now show signs of a tiny shift back towards greener conditions, apparently due to global warming.The researchers looked at ancient pollen, spores and aquatic organisms in sediments in Lake Yoa in northern Chad that show that the region gradually shifted from...
