Nanotechnology has been touted as the next technology revolution, transforming everything from communications to medicine, water decontamination to homeland security. But scientific progress has been accompanied by fears over unknown consequences of nanotechnology, with one pressure group even calling for a moratorium on all research until more is known. More specific concerns have been voiced by various parties – including the UK Royal Society and Royal Academy of Engineering – about exposure to manufactured nano-sized particles and the possible harmful effects on human health.
The future success of nanotechnology will depend on rational and informed work to understand and minimize these potential adverse effects on health and the environment. This is where Andrew Maynard of the Woodrow Wilson International Center for Scholars steps in. He explains what is known about effects of nanoparticles on the body in the latest issue of Nano Today magazine.
“We need to understand both how harmful a substance is, and how much of it can get into the body, if risk is to be understood and managed,” says Maynard.

For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.
According to Albert Einstein's Equivalence Principle, all bodies are accelerated at the same rate by the Earth's gravity, regardless of their properties. This...

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
