Despite complaints that Google Glass was too bulky and nerdy, rumours suggest the tech giant will release a new version with a larger prism display. The Enterprise Edition (EE) is also said to include an Intel Atom processor for improved performance and battery life. Some users of Glass, which was pulled in January following poor sales and mixed reviews, complained of eye strain after prolonged use. This may explain why Google might have decided to include a larger screen in its next design, 9to5Google reported. It’s rumoured that final iterations of the EE include a prism that extends further, allowing wearers to glance upwards and focus on the screen more comfortably than before.Rumours suggest Google will release a new version of Google Glass, dubbed the Enterprise Edition, with a larger prism displayImproved screen could help to reduce eye strain for wearersSmart specs are also said to include an Intel Atom processor for improved performance and battery life compared to the previous versionSome users of Glass, which was pulled in January following poor sales and mixed reviews, complained of eye strain after prolonged use

Satellite data show people are overdrawing water from some of the world's largest groundwater basins. Researchers from the University of California, Irvine say it's unclear how much water is left in the most overburdened aquifers. The problem is expected to worsen with climate change and population growth. The Arabian Aquifer System, an important water source for more than 60 million people, is the most overstressed in the world. The Indus Basin aquifer of northwestern India and Pakistan is the second-most overstressed, and the Murzuk-Djado Basin in northern Africa is third. California's Central Valley, used heavily for agriculture and suffering rapid depletion, was slightly better off, but was still labeled highly stressed in the first study.Arabian Aquifer System, an important water source for more than 60 million people, is the most overstressed in the worldResearchers say it's unclear how much water is left in most hard hit aquifers
