It is possible to create steam within seconds by focusing sunlight on nanoparticles mixed into water, according to new research. That observation, reported by scientists at Rice University in Texas, suggests myriad applications in places that lack electricity or burnable fuels. A sun-powered boiler could desalinate sea water, distill alcohol, sterilize medical equipment and perform…
The “uncrackable codes” made by exploiting the branch of physics called quantum mechanics have been sent down kilometres of standard broadband fibre. This “quantum key distribution” has until now needed a dedicated fibre separate from that used to carry data. The technique, reported in Physical Review X, shows how to unpick normal data streams from…
Scientists and ethicists call for public debate about the future use of drugs or other enhancements in the workplace
Fully fledged quantum computers are still a long way off. But devices that can simulate quantum systems are proving uniquely useful.
For years, scientists and engineers have been juggling various combinations of acids, steam, bacteria, catalysts and the digestive juices of microorganisms to convert agricultural waste and even household garbage into motor fuel. So far, such alternative fuels have not moved beyond small pilot plants, despite federal incentives to encourage companies to develop them. But that…
Obama wants to invest in science and technology, but a divided Congress and looming budget cuts could make it difficult to keep his promises.
John Wiley has reached an agreement with TED, the nonprofit specializing in spreading discussions on technology, entertainment, design and other subjects, to produce instructional material for TED Studies, 21 collections of curated discussions aimed at the school market and organized under academic subject categories. The Wiley/TED instructional content will be offered for free along with…
With the growth of online science networks, geography and economics no longer dictate how research is undertaken or published. Just as matchmaking sites connect romance-seekers based on their relationship compatibility, new academic social networks are connecting scientists based on their professional research interests. These sites obviously lack the general appeal of Facebook, which topped one…
The search for the Higgs boson using the Large Hadron Collider at Cern has taken years of research and cost billions. It is a prime example of big money being spent on fundamental research into scientific principles, that critics say provides no answers to the problems the world faces today. In these austere times and…
Using the power of the sun and ultrathin films of iron oxide (commonly known as rust), Technion-Israel Institute of Technology researchers have found a novel way to split water molecules into hydrogen and oxygen. The breakthrough, published this week in Nature Materials could lead to less expensive, more efficient ways to store solar energy in…
