 Stratasys Ltd., a manufacturer of 3D printers and production systems for prototyping and manufacturing, says that the "magic arms" WREX exoskeleton, designed by Nemours/Alfred l. duPont Hospital for Children, has been nominated for the Designs of the Year 2013 awards by London's Design Museum. 


While the cultural debate of nationalized health care is whether or not to let obese people and smokers die(1), a new paper in Spain says males are pressuring women to be thin and it is making females less happy.

The psychologists also contend that women who are not comfortable with their body perceive women with a normal body as a threat. Specifically, when these women see a "normal" body they experience feelings of displeasure and lack of control, since they feel they have not any control on their own body and cannot make it be as they want.


The sun has terrific energy potential but harnessing its electricity with silicon solar cells is too expensive; at times 10 times the price of coal energy it is fine for wealthier people but unrealistic in developing nations, where CO2 emissions are rising the fastest.


At least in America, CO2 emissions have dropped dramatically. The energy sector, the largest producer of CO2, is already back at early 1990s levels of emissions and the traditionally worst offender, coal, is at early 1980s levels.

CO2 is the primary greenhouse gas emitted by human activity. A simple way to measure climate sensitivity is to calculate how much the mean air temperature will rise if we were to double the level of overall CO2 emissions compared to the world's pre-industrialized level around the year 1750. If we continue to emit greenhouse gases at our current rate, estimates are that we risk doubling that atmospheric CO2 level in roughly 2050.


About ten percent of all cases of malignant melanoma are familial cases. The genome of affected families tells scientists a lot about how the disease develops. Prof. Dr. Rajiv Kumar of the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ) together with Prof. Dr. Dirk Schadendorf from Essen University Hospital studied a family where 14 family members were affected by malignant melanoma.


Decentralization is the greatest challenge facing energy companies in Germany - directing energy efficiently has become more important than how much to produce. 

"Distribution System Operators (DSO) and energy companies are working feverishly on various new models and technologies to ensure the right amounts of energy get to the right places at the right times, as well as attempting to pre-empt looming new questions," said Tobias Rothacher, Senior Manager of Renewable Energies and Resources at Germany Trade&Invest.

Electric cars of the future will present a whole host of new riddles in power availability that will need answering, as will eventual turns to electric forms of heating and/or cooling.
