Thinking without a brain: Studies in brainless slime molds reveal that they use physical cues to decide where to grow

If you didn't have a brain, could you still figure out where you were and navigate your surroundings? Thanks to new research on slime molds, the answer may be "yes." Scientists from the Wyss Institute at Harvard University and the Allen Discovery Center at Tufts University have discovered that a brainless slime mold called Physarum polycephalum uses its body to sense mechanical cues in its surrounding environment, and performs computations similar to what we call "thinking" to decide in which direction to grow based on that information. Unlike previous studies with Physarum, these results were obtained without giving the organism any food or chemical signals to influence its behavior. The study is published in Advanced Materials.

Teens with secure family relationships 'pay it forward' with empathy for friends

Teens' ability to empathize—to understand others' perspectives and emotions, and to care for their wellbeing—is an important contributor to their relationships, including with friends. Prior research shows that teens who have more secure family relationships report higher levels of empathy for others. But little research examines whether teens with more secure family relationships actually show greater empathy when observed in real-life interactions with peers, or whether their empathic capacities show different patterns of growth over time.
