That's the finding of a new longitudinal study conducted by researchers at the University of Montreal and the University of Minnesota. The research appears in the November/December 2010 issue of the journal Child Development.
The study, of 60 Canadian children at ages 1, 1-1/2, and 2, looked at the effects of infants' sleep on executive functioning. Among children, executive functioning includes the ability to control impulses, remember things, and show mental flexibility. Executive functioning develops rapidly between ages 1 and 6, but little is known about why certain children are better than others at acquiring these skills.
"We found that infants' sleep is associated with cognitive functions that depend on brain structures that develop rapidly in the first two years of life," explains Annie Bernier, professor of psychology at the University of Montreal, who led the study. "This may imply that good nighttime sleep in infancy sets in motion a cascade of neural effects that has implications for later executive skills."
When the infants were 1 year old and 1-1/2 years old, their mothers filled out three-day sleep diaries that included hour-by-hour patterns, daytime naps, and nighttime wakings. When the children were 1-1/2 and 2, the researchers measured how the children did on the skills involved with executive functioning.
Children who got most of their sleep during the night did better on the tasks, especially those involving impulse control. The link between sleep and the skills remained, even after the researchers took into consideration such factors as parents' education and income and the children's general cognitive skills. The number of times infants woke at night and the total time spent sleeping were not found to relate to the infants' executive functioning skills.
"These findings add to previous research with school-age children, which has shown that sleep plays a role in the development of higher-order cognitive functions that involve the brain's prefrontal cortex," according to Bernier.

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.
