The secret to desire in a long-term relationship
Who is talking? Psychotherapist and marriage coach Esther Perel.
What is she on about? The tension between desire and domestic life. She argues that erotic desire is not about toys, lingerie or Hollywood-derived spontaneity, but the freedom to keep exploring life away from your partner.
Is she right? You would have to ask the couples she works with.
Highlight: Her thesis that “the erotic mind is not very politically correct” because “most of us will get turned on at night by the very same things we protest about during the day.”

Printing a human kidney
Who is talking? Anthony Atala, a surgeon and director of the Wake Forest Institute for Regenerative Medicine.
What is he on about? The capacity of 3D-printing technology to one day solve the organ-donor problem by printing human kidneys one layer of cells at a time.

Do schools kill creativity?
Who is talking? Educationalist, author, academic and government adviser Kenneth Robinson.

Is he right? Perhaps. He is certainly popular. With over 23 million views, Robinson’s 20-minute lecture is the most-watched TED talk so far.

Moral behavior in animals
Who is talking? Professor Frans de Waal, a primatologist.
What is he on about? The capacity of animals to cooperate and empathize with one another, as demonstrated by chimps, elephants and capuchin monkeys. De Waal argues that this capacity in animals suggests morality has prehuman evolutionary roots.
Is he right? Perhaps, although the explanation may have more to do with survival than any meaningful notion of altruism.
Highlight: The capuchin monkeys rejecting unequal pay.
