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.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
