Summary: Cortical representations for the sounds and meanings of new words learned form within an hour or two following exposure.

How much time does a brain need to learn a new word? A team of Skoltech researchers and their colleagues monitored changes in brain activity associated with learning new words and found that cortical representations of the sound and meaning of these words may form in just 1 to 2 hours after exposure without any night’s sleep consolidation, as earlier research suggested. This research has implications for diagnosing speech disorders and improving the efficiency of learning. The paper was published in the journal Frontiers in Neuroscience.

Ira Pastor Comments:

Getting blood drawn is not a fun activity for many. It can be scary for some (especially if you have children); it can be painful for others (especially where frequent blood draws are required).

Studies show that a remarkable 20% of the population has some degree of fear of needles or injections, and 10% within that number suffer from what is known as Trypanophobia (a psychological term for people with an extreme fear of medical procedures involving injections or hypodermic needles), who on top of their anxiety, completely avoid necessary tests and treatment.

One of the more curious challenges in physics is to understand the nature of time. At the microscopic level, the laws of physics are symmetric with respect to time—they work just as well whether time runs forwards or backwards. But at the macroscopic level, processes all have a preferred direction. The great physicist Arthur Eddington called this the “arrow of time.”

Just why this arrow points in one direction but not the other is one of the great scientific puzzles. The standard answer is that the arrow of time follows from the Second Law of Thermodynamics—that disorder, or entropy, always increases in a closed system.

That’s why milk mixes easily in tea but never emerges from a brew, why scrambled eggs never spontaneously unscramble, and why your morning mug of coffee heats your hands as you hold it and not the other way around.
