In which foods and products are nanoparticles used? In what ways do consumers come into contact with nanoparticles? Does this lead to health risks? How can they be assessed? What information do consumers need about nanotechnologies? At the sixth BfR Consumer Protection Forum at the Federal Institute for Risk Assessment (BfR) in Berlin the list of questions from the 200 participants to be addressed was long.
Two physicists may have found an easier way to make things invisible. Cloaking devices, which are a form of advanced stealth technology, are used to render spacecraft invisible in Star Trek. So far all methods for invisibility require exotic materials and would only work at certain colours of light.
140 years since its discovery, and despite the best endeavours of many scientists, helium, the lightest of the 'noble' gases, still stubbornly refuses to enter into any chemical alliance. Now a new glimmer of hope has emerged as a chemist has calculated that two new compounds containing a helium-oxygen bond could be formed.
Just as artists at Disney and Pixar Animation Studios bring Mickey Mouse, Shrek and Nemo to life, life science artists are using animation to bring viruses, bacteria and even nanowires to life and demystify scientific concepts.
An EU-funded study by physicists in Germany, France and Hungary has demonstrated conclusively that the Standard Model of particle physics, a theory describing the fundamental interactions of the elementary particles that make up all visible matter in the universe, accurately accounts for the mass of protons and neutrons.
A team at Rice University has determined that a strip of graphite only 10 atoms thick can serve as the basic element in a new type of memory, making massive amounts of storage available for computers, handheld media players, cell phones and cameras.
A memorandum of understanding for cooperation on renewable energy sources was signed between the CAS Institute of Electrical Engineering (IEE) and the US National Renewable Energy Laboratory (NREL) on 11 November in Beijing.
The next generation of solar panels promises to be less conspicuous and expensive, but the technology still needs to be made more efficient, said Prof. Alan Heeger, winner of the 2000 Nobel Prize in Chemistry, during a lecture Thursday.
