New Battery Can Be Bent, Stretched, and Twisted

As researchers eye flexible form factors for mobile and electronic devices of the future, it makes sense that engineers also are working to invent batteries and other components that also can stretch to accommodate these designs. To that end, a team of researchers in Switzerland has developed a battery that can be bent, stretched, and twisted, making it well-suited for these future devices, said Markus Niederberger, professor for multifunctional materials at ETH Zurich, where the research was conducted.

If you want to roll or bend such a device, you also have to be able to bend or stretch the battery.” Niederberger said the company took a unique approach to design the battery that allowed them to build it layer by layer of flexible components, something that has historically been nearly impossible to achieve. “In the scientific literature, there is a lot of work on the individual components that are made flexible,&a...

(Reuters Health) - Consumers might make healthier choices if food labels showed how many minutes of walking or running was needed to burn off calories, instead of just a calorie number, a new study suggests.

For example, such labeling would show that a person would need to walk 42 minutes or run 22 minutes to burn off the 229 calories in a small bar of milk chocolate, said British researchers.

CONCLUSIONS: Reproducibility of a scientific method is the basis to prove the veracity of the observed results. Thus, it is necessary to have a greater number of publications that adopt a reproducible scientific method, for this review found inconsistencies in the description of Walker and Mason's model.
