ROME - Have you ever asked yourself whether you were awake or asleep? As it turns out, in our brain, and especially in our memory, there is not much difference between being awake or being asleep. A new study by Italian researchers delves into this gray area, discovering clues about the brain process that allows us to remember our dreams the morning after.

The study, whose findings were just published in the Journal of Neuroscience, aims to answer two key questions: "Why do we sometimes forget and other times remember the dreams when we awake?" and "Do these two options involve different areas of our brain?"

In any case, this is what Putin — who put Russia's nuclear forces on alert just after the start of the invasion in late February — is aiming to achieve: to terrorize populations in Western countries to push their leaders to let go of Ukraine.

Central to the tragic absurdity of this war is the question of language. Vladimir Putin has repeated that protecting ethnic Russians and the Russian-speaking populations of Ukraine was a driving motivation for his invasion.

Yet one month on, a quick look at the map shows that many of the worst-hit cities are those where Russian is the predominant language: Kharkiv, Odesa, Kherson.
