Women remain much choosier than men when it comes to dating. Is this difference a vestige of our early ancestry? Or could it be the result of something more modern and mundane?
Evolutionary psychologists have long thought that women are choosier than men when it comes to dating because in prehistoric times "dating" was much riskier for women—men could shrug off a one-night-stand, while women who chose an unfit mate could end up with years of motherhood without the help of a stable partner. "That is less true today, yet women remain much more selective," notes Wray Herbert. "Is this difference a vestige of our early ancestry? Or might it be totally unrelated to reproductive risk, the result of something more modern and mundane?"

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

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