Scientists in Mexico, home of the taco, found that tortillas made from blue corn had less starch and a lower glycæmic index than their white counter parts. They also found that the blue tortillas had 20% more protein than white (Journal of the Science of Food and Agriculture, DOI 10.1002/jsfa.3008).
The glycæmic index (GI) ranks carbohydrates according to their effects on blood glucose levels. Foods with a lower GI are considered healthier as they slowly release sugar into the bloodstream. This reduces fluctuations in our blood glucose and insulin levels, helping to maintain a steady supply of energy. Low GI foods are said to have long-term health benefits, reducing your risk of heart disease and diabetes as well as aiding and maintaining weight loss.
Juscelino Tovar, an author of the study, said that one important benefit of the lower GI blue tortillas is their potential role in preventing or controlling metabolic syndrome, a combination of disorders which increase the risk of heart disease, stroke and diabetes.
NB The blue colouring is due to the presence of anthocyanins in the corn. These are the same health promoting compounds found purple berries and red wine.

At the 2018 ILA Berlin Air Show from April 25–29, the Fraunhofer Institute for Laser Technology ILT is showcasing extreme high-speed Laser Material Deposition (EHLA): A video documents how for metal components that are highly loaded, EHLA has already proved itself as an alternative to hard chrome plating, which is now allowed only under special conditions.
When the EU restricted the use of hexavalent chromium compounds to special applications requiring authorization, the move prompted a rethink in the surface...
At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.
Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
