Low levels of folic acid in plasma have been associated with an increased risk of miscarriage in a study published in Journal of the American Medical Association lately. On the other hand, no connection was found between high levels of folic acid and increased risk of miscarriage.
In the US folic acid is added to flour to prevent pregnant women from developing a deficit of folic acid. Previous studies have shown that both deficits and surpluses of folic acid can heighten the risk of miscarriage. In Sweden today there is no folic acid additive in foodstuffs.
“The result of our study can provide another piece of the puzzle for the Swedish National Food Agency to take into consideration. Those countries that add folic acid to foods can continue to do so,” says Professor Sven Cnattingius at Karolinska Institutet in Sweden.

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...
