Zuckerberg's huge pledge reflects a new era in philanthropy
Posted on: 03 Dec 2015
The huge philanthropic pledge by Facebook CEO Mark Zuckerberg and his wife—totaling perhaps $45 billion—reflects the fast-paced emergence of a new Gilded Age of giving. The changes excite many in the charity world, but also raise questions about effectiveness, ethics and the impact on older charities that may not share in any windfall.
Runner’s GPS build
Posted on: 02 Dec 2015
Home This project is to build a portable GPS geared towards runners (well, me and what I think a runner wants a GPS thingy for). It’s sponsored by the University of Minnesota’s ECE Envision Fund. The hardware is basically complete, and the software is functional, if not polished. This is what the main screen looks like […]
Addressing climate change should start with policies to increase energy efficiency
Posted on: 02 Dec 2015
Replacing an old incandescent lightbulb with new LED lighting might seem insignificant in reducing energy consumption. It is a simple step, but an effective one that shouldn’t be overlooked, said Yu Wang, an assistant professor of political science, who studies global energy policy and energy efficiency, at Iowa State University.

I was frustrated by trying to remember my passwords for all my websites and got even more frustrated when i need to change a password again after some months. Dont even to mention the needed complexity of them nowadays. A bit insired by the mooltipass featured on hackaday, but too scared of the complexity and […]
Physicists confirm thermodynamic irreversibility in a quantum system
Posted on: 01 Dec 2015
(Phys.org)—For the first time, physicists have performed an experiment confirming that thermodynamic processes are irreversible in a quantum system—meaning that, even on the quantum level, you can’t put a broken egg back into its shell. The results have implications for understanding thermodynamics in quantum systems and, in turn, designing quantum computers and other quantum information technologies.

Six years of pest fruit fly species investigation compiled in a new special volume
Posted on: 30 Nov 2015
Considered among the agricultural pests with the greatest economic impact, the tephritid fruit flies (Diptera: Tephritidae) are a serious worldwide problem. Destroying fruit and vegetable production and markets across all major continents, some key species have raised international attention, leading to six years of coordinated multidisciplinary research that will contribute to overcome phytosanitary trade barriers and apply more sustainable pest management strategies such as the Sterile Insect Technique (SIT).
