The Politics of Your Eyes
Liberals and conservatives have different ways of looking at other people—literally. Scientists say that conservatives tend to ignore what other people look at.
In a recent study, psychologists from the University of Nebraska at Lincoln studied how liberals and conservatives respond to "gaze cues," which refer to "a person's tendency to shift attention in a direction consistent with another person's eye movements." In a release about the report, the University of Nebraska explains: Liberals responded strongly to the prompts, consistently moving their attention in the direction suggested to them by a face on a computer screen. Conservatives, on the other hand, did not. Why? Researchers suggested that conservatives' value on personal autonomy might make them less likely to be influenced by others, and therefore less responsive to the visual prompts.

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.
Does believing in true love make people act like jerks?
- 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.
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.
