The idea that a woman’s emotional state during pregnancy affects her unborn child has persisted for centuries and has, in recent years, been supported by science. Called the "fetal programming hypothesis," it theorizes that certain disturbing factors occurring during certain sensitive periods of development in utero can "program" set points in a variety of biological systems in the unborn child. This, then, affects the ability of those biological systems to change later in life, resulting in difficulties adapting physiologically and ultimately predisposing a child to disease and disorder.
We decided to investigate the affect of high levels of anxiety during a woman’s pregnancy on her child’s susceptibility for attention deficits, hyperactivity, acting out and anxiety disorders in childhood. We also wanted to learn whether there are specific vulnerable periods during the pregnancy in which this anxiety "programs" the child’s biological system, thus increasing the fetus’ susceptibility for such disorders.
We evaluated data collected on 71 normal mothers and their 72 first-born children during pregnancy and when their children were 8 or 9. The mothers completed questionnaires to measure their anxiety levels throughout their pregnancy. When the children were 8 or 9, the mothers, a teacher, and an impartial observer completed questionnaires to measure the child’s attention and hyperactivity, acting-out behavior and anxiety level.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
