Top quality colour printing could be revolutionised thanks to the revival in Bristol of an old printing process once used to create, among other things, colour charts for selecting glass eyes. Art researchers from the University of the West of England have discovered a 21st century use for the process, known as collotype, which fell out of favour during the early 1900s. As an added bonus, new inks are being developed which unlike current computer colour printouts, won`t fade over time.

Photovoltaics is a science that examines light-electricity conversion. Conversion of solar energy carried by photons is transformed by solar cells into direct-current electrical energy. Interest in the use of photovoltaic (PV) solar technologies is growing rapidly, as it will permit the direct production of electricity from solar radiation without any harmful emissions or noise. Rising energy costs, the finite nature of fossil fuels and worries about climate change has renewed interest in making the

Along with Canadian colleagues, a University of North Carolina at Chapel Hill scientist has discovered fossils of plants dating back some 420 million years.

The discovery, made on Bathurst Island in the Northwest Territories about 800 miles from the North Pole, shows vascular plants were more complex at that time than paleontologists previously believed and is significant for that reason, the UNC researcher said.

“These are not the earliest vascular plants ever found, but they are

New measurements show that the flow of ice in the Greenland ice sheet has been accelerating since 1996 during the summer melt season. The results suggest that the ice sheet may be responding more quickly to the warming climate than previously thought.

Ph.D. candidate Nina Isoherranen wins Kaye Awards

Nina Isoherranen, a Ph.D. candidate at the Hebrew University School of Pharmacy, was awarded a Kaye Innovation Award this week for developing a new medication to treat epilepsy, migraine headaches, and chronic pain that does not cause birth defects in animal models, unlike other medicines currently used to treat epilepsy.

Ms. Isoherranen explained that 1% of the population suffers from epilepsy, a central nervous system (CNS)

Inks which cannot be photocopied – to confound bank-note forgers – are exciting printers of most of the world`s major currencies. A team from colour chemistry, led by Professor David Lewis and Dr Long Lin, has created an ink which changes colour when copied or scanned, to prevent forgers colour matching banknotes.

“There are already hundreds of security measures in place for banknotes,” said Professor Lewis. “But these don`t stop forgeries – some estimates put the number of forged banknotes
