A new study from the University of Alberta suggests it may be better to enroll your child in the first grade later than sooner.
The study says that students who entered Grade 1 at an older age relative to their classmates scored significantly better years later on tests that measure self-esteem. This is important, the study’s authors say, because there is much evidence linking higher self-esteem in childhood to happier, healthier, and more successful lives as adults.
Conversely, lower self-esteem in childhood can lead to the development of a variety of emotional disturbances and an increased risk of suicide, added Dr. Gus Thompson, lead author of the study and a population health professor at the U of A. "Given all this evidence, I would encourage parents to consider deferring school entry if the child is going to be among the youngest in Grade 1," he said.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
