The pressure on the environment of building during the past 5000 years can be observed clearly from the air. In a recent lecture at the Society of Chemical Industry (SCI), aerial photographer and concrete specialist Christopher Stanley illustrated the evolution of construction and its lasting impact, from stone circles to skyscrapers.
Stanley’s lecture ‘Managing the environment: a perspective from land, air and sea’ followed the presentation of the 2002 SCI Environment Medal in recognition of his contributions to improving the built environment. A Fellow of the Institute of Concrete Technology, Hong Kong, Christopher Stanley identified the constraints caused by environmental concerns on quarrying and aggregate supplies in the region. Previously, waste concrete from demolitions was just tipped into Hong Kong bay, but there is now a move to crush concrete and reuse it as an aggregate in new building work.
Stanley explained that the development of communities, from hamlets to towns to the modern metropolis, has left its mark on the environment. The advent of new building materials and the change in social patterns within modern developments has also altered the environments in which people live and work.

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
