How will global warming affect life on Earth? Uncertainties about future climate change and the impact of human activity make it difficult to predict exactly what lies ahead. But the past offers clues, say scientists who are studying a period of warming that occurred about 55 million years ago.
In a joint project of the University of Michigan, the University of New Hampshire and the Smithsonian Institution, researchers have been analyzing fossils from the badlands of Wyoming found in a distinctive layer of bright red sedimentary rock that was deposited at the boundary between the Paleocene and Eocene epochs---a time of apparent sudden climate change. The researchers described their findings in a paper presented Feb. 16 at the annual meeting of the American Association for the Advancement of Science.
"The interval of Earth history that were studying is marked by a short-term global warming event thought to have occurred when something triggered the release of methane from methane clathrate---a kind of methane ice found in ocean sediments," said Philip D. Gingerich, professor of geological sciences at the University of Michigan. Within about 10,000 years of peak warming, mammals such as primates and the groups that include horses and deer appeared together for the first time in North America, apparently having crossed land bridges from other continents.

Optical quantum computers can revolutionize computer technology. A team of researchers led by scientists from Münster University and KIT now succeeded in putting a quantum optical experimental set-up onto a chip. In doing so, they have met one of the requirements for making it possible to use photonic circuits for optical quantum computers.
Optical quantum computers are what people are pinning their hopes on for tomorrow’s computer technology – whether for tap-proof data encryption, ultrafast...
The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP has been developing various applications for OLED microdisplays based on organic semiconductors. By integrating the capabilities of an image sensor directly into the microdisplay, eye movements can be recorded by the smart glasses and utilized for guidance and control functions, as one example. The new design will be debuted at Augmented World Expo Europe (AWE) in Berlin at Booth B25, October 18th – 19th.

With the help of artificial intelligence, chemists from the University of Basel in Switzerland have computed the characteristics of about two million crystals made up of four chemical elements. The researchers were able to identify 90 previously unknown thermodynamically stable crystals that can be regarded as new materials. They report on their findings in the scientific journal Physical Review Letters.
