A project supported by the Austrian Science Fund FWF wants to uncover the history, significance and precise origins of Islamic art contained in Viennese art collections; comprehensive work to reconstruct the background of several Ottoman flags has already been carried out with impressive results.

Traces of the era of the Turkish wars - such as the tradition of the Vienna coffee house and the Ring boulevard that encircles the city centre - are still evident today in the day-to-day culture and street layout of the Austrian capital. The Turkish sieges of Vienna (16th/17th century) led to an expansion of the city's fortifications and heralded the introduction of coffee.

People are always going on about the life expectancy of babies and people in general.   Now quantum states are getting their due.

For the first time, scientists have succeeded in measuring and controlling the lifetime of quantum states with potential use in optoelectronic chips. This achievement is highly significant for the ongoing development of this cutting-edge technology. The breakthrough involved measuring the intersubband relaxation time of charge states in silicon-germanium SiGe structures on a picosecond scale. Experiments have also shown that it is possible to control and extend these times. As a result, this body of work  represents a major advance in the development of data processing based on optoelectronic chips.

Fat people require more food and that requires more farming and greenhouse gas emissions.  Therefore, maintaining a healthy body weight is also good for the environment, according to a study which appears today in the International Journal of Epidemiology.

They highlight poor, third world countries like Vietnam as a model because they they can't afford food so they consume almost 20% less of it (and therefore cause fewer greenhouse gases to be produced) than a population in which over 40% of people are obese, where the USA and a few nations in Europe are heading by 2020.

Global warming gets all the press today but there was a time when pollution-caused global cooling was the concern - and if you map the planet's recent history, 90,000 out of every 100,000 years were ice ages and it's been 12,000 years since the last one so the historical reason for concern was not unfounded.  A new book, "The Late Eocene Earth - Hothouse, Icehouse, and Impacts" tackles what global cooling was like.

New evidence gleaned from CT scans of fossils locked inside rocks may flip the order in which two kinds of four-limbed animals with backbones were known to have moved from fish to landlubber.

Both extinct species, known as Ichthyostega and Acanthostega, lived an estimated 360-370 million years ago in what is now Greenland. Acanthostega was thought to have been the most primitive tetrapod, that is, the first vertebrate animal to possess limbs with digits rather than fish fins. 

The ferroelectric materials found in today's "smart cards" used in subway, ATM and fuel cards soon may eliminate the time-consuming booting and rebooting of computer operating systems by providing an "instant-on" capability as well as preventing losses from power outages.

Researchers supported by a National Science Foundation (NSF) nanoscale interdisciplinary research team award and three Materials Research Science and Engineering Centers at Cornell University, Penn State University and Northwestern University recently added ferroelectric capability to material used in common computer transistors, a feat scientists tried to achieve for more than half a century.
