| Roman seawater concrete holds the secret to cutting carbon emissions  | Scientists analyzed samples from a Roman breakwater submerged in the Bay of Naples for over two millennia, revealing the secrets of crystal chemistry that allow Roman seawater concrete to resist chemical attack and wave action for centuries. Materials and processes for manufacturing extraordinarily durable Roman maritime concrete released much less carbon than most modern concrete, presenting important opportunities for better quality and reduction of atmospheric carbon. | Read More »  Bringing cheaper, 'greener' lighting to market with inkjet-printed hybrid quantum dot LEDs  | It's not easy going green. For home lighting applications, organic light emitting diodes (OLEDs) hold the promise of being both environmentally friendly and versatile. Though not as efficient as regular light-emitting diodes (LEDs), they offer a wider range of material choices and are more energy efficient than traditional lights. OLEDs can also be applied to flexible surfaces, which may lead to lights or television displays that can be rolled up and stowed in a pocket. | Read More » Biomarker could help scientists choose the right cell line when conducting stem cell experiments  | Stem cells that strongly express a gene called WNT3 are biased to develop into cells and tissues including pancreas, liver and bladder. This discovery suggests that other genes may serve as biomarkers for selecting stem cells with a preference for turning into different tissue types. Such markers would make it easier for stem cell scientists to choose the right cell line to start with when generating specific tissues for study. | Read More » Genetic editing shows promise in Duchenne muscular dystrophy  | Using a novel genetic "editing" technique, biomedical engineers have been able to repair a defect responsible for one of the most common inherited disorders, Duchenne muscular dystrophy, in cell samples from Duchenne patients. | Read More » Heart health matters to your brain  | People suffering from type 2 diabetes and cardiovascular disease (CVD) are at an increased risk of cognitive decline, according to a new study. | Read More » Tiny airplanes and subs could be next hurricane hunters  | Scientists envision a day when unmanned vehicles will swarm over, under and through hurricanes to help predict the strength and path of the storms. | Read More » Spintronics approach enables new quantum technologies  | Researchers highlight the power of emerging quantum technologies in two recent articles.
