The Coming Population Decline

As women in rising countries like China, Iran and Turkey lead increasingly independent lives, they are having children later in life and in fewer numbers which could prevent the much-feared population crisis.

As women in rising countries like China, Iran and Turkey lead increasingly independent lives, they are having children later in life and in fewer numbers which could prevent the much-feared population crisis. Fred Pearce has written a book on the matter called: The Coming Population Crash, and Our Planet's Surprising Future. He has recently written an article for Scientific American saying that "Women are having smaller families and grabbing a new life outside the home because, for the first time in history, they can. In the 20th century, the world largely eradicated the diseases that used to mean most children died before growing up. Mothers no longer need to have five or six children to ensure the next generation. So they do not. Two or three is enough."

Why is 18 the age of adulthood if the brain can take 30 years to mature?

Neuroscience research suggests it might be time to rethink our ideas about when exactly a child becomes an adult.

Mind & Brain
  • Research suggests that most human brains take about 25 years to develop, though these rates can vary among men and women, and among individuals.
  • Although the human brain matures in size during adolescence, important developments within the prefrontal cortex and other regions still take pace well into one's 20s.
  • The findings raise complex ethical questions about the way our criminal justice systems punishes criminals in their late teens and early 20s.

Does believing in true love make people act like jerks?

Sex & Relationships
  • Ghosting, or cutting off all contact suddenly with a romantic partner, is not nice.
  • Growth-oriented people (who think relationships are made, not born) do not appreciate it.
  • Destiny-oriented people (who believe in soulmates) are more likely to be okay with ghosting.

Mini-brains attach to spinal cord and twitch muscles

A new method of growing mini-brains produces some startling results.

(Lancaster, et al)
Surprising Science
  • Researchers find a new and inexpensive way to keep organoids growing for a year.
  • Axons from the study's organoids attached themselves to embryonic mouse spinal cord cells.
  • The mini-brains took control of muscles connected to the spinal cords.
