Traditional concrete is so last century. A team of engineers has created a concrete that is strong but flexible, can generate electricity and have its qualities fine-tuned for tailor-made builds. And one day it might even help guide driverless cars.

By using a labeling system, a research team found that it was possible to shift dining choices away from climate-straining red meat consumption and towards more eco-friendly plant-based options.

A hormone released by muscles during exercise has been found to reduce levels of a protein associated with Parkinson’s disease. The promising animal study indicates future therapies may be developed based on the way this hormone improves brain health.

With the fitness wearable market exploding in popularity a team of researchers wondered whether these devices could be used to detect the earliest signs of dementia. A new study suggests that could be possible.
