New research findings published online in The FASEB Journal provide more evidence that if we get smart about what we eat, our intelligence can improve. According to MIT scientists, dietary nutrients found in a wide range of foods from infant formula to eggs increase brain synapses and improve cognitive abilities.
"I hope human brains will, like those of experimental animals, respond to this kind of treatment by making more brain synapses and thus restoring cognitive abilities," said Richard Wurtman, MD, senior researcher on the project.
In the study, gerbils were given various combinations of three compounds needed for healthy brain membranes: choline, found in eggs; uridine monophosphate (UMP) found in beets; and docosahexaenoic acid (DHA), found in fish oils. Other gerbils were given none of these to serve as a baseline. Then they were checked for cognitive changes four weeks later. The scientists found that the gerbils given choline with UMP and/or DHA showed cognitive improvements in tasks thought to be relevant to gerbils, such as navigating mazes. After these tests were concluded, the researchers dissected the mouse brains for a biological cause for the improvement. They found biochemical evidence that there was more than the usual amount of brain synapse activity, which was consistent with behaviors indicating higher intelligence.
"Now that we know how to make gerbils smarter," said Gerald Weissmann, MD, Editor-in-Chief of The FASEB Journal, "it's not too far a stretch to hope that people's intelligence can also be improved. Quite frankly, this can't happen soon enough, as every environmentalist, advocate of evolution and war opponent will attest."

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
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.
