To come to this conclusion, researchers first measured docosahexaenoic acid (DHA) concentration—a type of omega-3 fatty acid involved in the development of neurons and retinas—in the umbilical cord blood of 109 infants. “DHA concentration in the umbilical cord is a good indicator of intra-uterine exposure to omega-3s during the last trimester of pregnancy, a crucial period for the development of retinal photoreceptors and neurons,” explains Dr. Dewailly.
Tests conducted on these infants at 6 and 11 months revealed that their visual acuity as well as their cognitive and motor development were closely linked to DHA concentration in the umbilical cord blood at the time of their birth. However, there was very little relation between test results and DHA concentration in a mother’s milk among infants who were breast-fed. “These results highlight the crucial importance of prenatal exposure to omega-3s in a child’s development,” points out Dr. Muckle.
Researchers observed that DHA concentration in the umbilical cord blood was in direct relation with the concentration found in a mother’s blood, a reminder of the importance of a mother’s diet in providing omega-3 fatty acids for the fetus. They also noted that DHA concentration was higher in the fetus’s blood than in the mother’s. “While developing its nervous system, a fetus needs great quantities of DHA. It can even transform other types of omega-3s into DHA in order to develop its brain,” explains Dr. Dewailly.
For the members of the research team, there is no doubt that all pregnant women should be encouraged to get sufficient amounts of omega-3s. “A diet rich in omega-3s during pregnancy can’t be expected to solve everything, but our results show that such a diet has positive effects on a child’s sensory, cognitive, and motor development. Benefits from eating fish with low contaminant levels and high omega-3 contents, such as trout, salmon, and sardines, far outweigh potential risks even during pregnancy,” conclude the researchers.

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“.

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.
