We already knew that sleeping helped to reinforce what we’ve learned. But today, a study at the ULg demonstrates for the first time that the brain doesn’t wait until night to structure information. Day and night, the brain doesn’t stop (re)working what we learn.
Positron Emission Tomography (PET-scan) studies carried out recently at the ULg Cyclotron Research Centre have revealed the reactivation of cerebral activity associated with learning new information in humans while they sleep. (1,2) This supports the hypothesis of the role of sleep in memorizing.
Taking advantage of the new opportunities offered by 3 Tesla’s functional Magnetic Resonance Imaging (fMRI)(*), Philippe Peigneux and his colleagues at the University of Liege published findings this week in the international journal PLoS Biology (3). Their study revealed for the first time a phenomenon that occurs during active waking that is similar to reactivation of the cerebral activity linked to learning.

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...
