As 3-D printing has become a mainstream technology, industry and academic researchers have been investigating printable structures that will fold themselves into useful three-dimensional shapes when heated or immersed in water.

In a paper appearing in the American Chemical Society’s journal Applied Materials and Interfaces, researchers from MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) and colleagues report something new: a printable structure that begins to fold itself up as soon as it’s peeled off the printing platform.

Technologies that allow the preservation of scarce fossil resources will pave the way towards resource security. The two main factors that contribute to a sustainable future industry are the source of electric energy and the carbon feedstock. First, the electrical power production based on renewable resources, such as wind and solar energy, is promoted. Second, renewable feedstocks and waste streams are considered as valuable precursors for the production of commodities and fuels. Building a bridge between both factors means linking the conversion of electric energy - especially from local peak productions - to chemical energy carriers and commodities. Researchers in a consortium led by Dr. Falk Harnisch from the UFZ show that this bridge can be build.

Former Hurricane Otis was not showing any thunderstorm development or precipitation on satellite imagery on Sept. 19. As a result, the National Hurricane Center declared Otis a remnant low pressure area.

At Carnegie Mellon, Professor Peter Adams is working to make sure that everyone who is affected by air pollution has the tools they need to understand the quality of their air.  When we talk about studying air pollution, we typically think of official government agencies and university labs, measuring particles and tracking wind speed—and with good reason. Until very recently, modeling the movement of pollution in the air required very complex calculations—models that often took days and even weeks to run. But air quality affects everyone: not just governments and universities, but average citizens, children, pets. At Carnegie Mellon, Civil and Environmental Engineering (CEE) and Engineering and Public Policy (EPP) Professor Peter Adams is working to make sure that everyone who is affected by air pollution has the tools they need to understand the quality of their air.

Teenagers who try e-cigarettes double their risk for smoking tobacco cigarettes, according to a new study.

The study — from the University of Waterloo and the Wake Forest School of Medicine — found that students in grades seven to 12 who had tried an e-cigarette are 2.16 times more likely to be susceptible to cigarette smoking.
