How can we preserve prehistoric artworks like those in southern France's Lascaux caves while still allowing modern visitors to experience them in some way?

In Transcranial Direct Current Stimulation, an electrical current is applied to the head and passed to the brain. Preliminary results suggest that TDCS could enhance memory and learning.

While we can manipulate elaborate equations with square roots and derivatives, new research shows monkeys can “count” audible beeps and equate them to visual representations of the same amount.
