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.

Spectrally narrow x-ray pulses may be “sharpened” by purely mechanical means. This sounds surprisingly, but a team of theoretical and experimental physicists developed and realized such a method. It is based on fast motions, precisely synchronized with the pulses, of a target interacting with the x-ray light. Thereby, photons are redistributed within the x-ray pulse to the desired spectral region.
A team of theoretical physicists from the MPI for Nuclear Physics (MPIK) in Heidelberg has developed a novel method to intensify the spectrally broad x-ray...
Physicists working with researcher Oriol Romero-Isart devised a new simple scheme to theoretically generate arbitrarily short and focused electromagnetic fields. This new tool could be used for precise sensing and in microscopy.
Microwaves, heat radiation, light and X-radiation are examples for electromagnetic waves. Many applications require to focus the electromagnetic fields to...
Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers
Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...
Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
