Researchers have known for some time of monochromatic light beams, such as Laguerre-Gauss beams, which carry orbital angular momentum also have a helical phase profile. According to Ole Steuernagel of the University of Hertfordshires Science and Technology Research Institute, UK, have helical wave fronts and can be made visible using interferometry. Such dark helices can […]
Finding sustainable alternatives to fossil fuels that would both solve the problem of dwindling supplies of oil and cut the net carbon dioxide emissions from vehicles running on hydrocarbon fuels is a cause high on the environmental agenda. The use of biomass as a source for fuels compounds has benefits, but the setting aside of […]
First electronic optical fibers with hydrogenated amorphous silicon are developed - A new chemical technique for depositing a non-crystalline form of silicon into the long, ultra-thin pores of optical fibers has been developed by an international team of scientists in the United States and the United Kingdom. The technique, which is the first of its […]
The TNA world that came before the RNA one - The question of how non-living chemicals emerged from the so-called primordial soup to give rise to life on Earth is one of the most intriguing in science. Finding an answer might not only help explain our origins but could give us important clues as to […]
