Can breakdown cleaning agent residuals and pesticides as well as pharmacological substances  Many harmful substances in waste water stubbornly resist being broken down by biological waste water treatment plants. Fraunhofer researchers have developed a photochemical reaction system in which water can be reliably treated at high flow rates by UV light without having to add

Key findings indicate wind energy prices at all-time lows as wind turbines grow larger Wind energy pricing remains attractive, according to an annual report released by the U.S. Department of Energy and prepared by Lawrence Berkeley National Laboratory (Berkeley Lab). At an average of around 2 cents per kilowatt-hour (kWh), prices offered by newly built

Genetic archaeology may help save wheat from climate change A genetic archaeologist of sorts, Cary Fowler works to save the wild species threatened by crop domestication. Fowler is the executive director of the Global Crop Diversity Trust, an organization that seeks to preserve the genetic diversity of plants in seed banks. By providing a backup of

Instead of being constrained by only being able to study sick patients, this platform projects virtual illnesses onto healthy subjects. The Hannover Medical School has developed an augmented reality simulation app called mARble that enables med students to get as much hands-on experience as they’d like. Instead of being constrained by only being able to study sick patients,

Computers will someday soon automatically provide short video digests of a day in your life, your family vacation or an eight-hour police patrol, say computer scientists at The University of Texas at Austin. The researchers are working to develop tools to help make sense of the vast quantities of video that are going to be

Asier Marzo has worked with the professor at the University of Bristol Bruce Drinkwater on this technology that could be used for surgical operations without incisions Asier Marzo-Pérez, researcher at the Public University of Navarre (NUP/UPNA), and Bruce Drinkwater, lecturer at the University of Bristol (United Kingdom), have for the first time achieved the acoustic

Image via Wikipedia THE print hanging behind the receptionist’s desk at Foundation Capital screams, “Our greatest thrill is to loan you money” — in chunky, capitalized red letters. That’s encouraging news for Michael Bauer, because he wants money and has put himself in a prime position to get it. Mr. Bauer has set up shop

MIT researchers develop an organic solar cell that breaks 100 percent quantum efficiency Solar cells are picky. If an incoming photon has too little energy, the cell won’t absorb it. If a photon has too much, the excess is wasted as heat. No matter what, a silicon solar cell can never generate more than one

“Create electricity, just by walking” “Create electricity, just by walking” is an evocative statement, and one which surely warrants some attention in these eco-efficient times when the need to seek alternative energy sources is well understood. Pavegen – a system for harvesting kinetic energy from foot traffic, and which the catchy soundbite belongs to –

I.B.M. researchers said Thursday that they had designed high-speed circuits from graphene, an ultra-thin material that has a host of promising applications, from high-bandwidth communication to a new generation of low-cost smartphone and television displays. The I.B.M. advance, which the researchers reported in the journal Science, is a circuit known as a broadband frequency mixer
