High moral reasoning associated with increased activity in the human brain's reward system

A new study from Penn researchers found a strong association between high moral reasoning and increased activity in the brain's reward system. This link suggests that positive motivations towards others play a crucial role in moral reasoning development, with higher levels of morality linked to more advanced principles and ethical rules.

Mouse model of human immune system inadequate for stem cell studies

A study by Stanford researchers found that a widely used mouse model of the human immune system is inadequate for studying stem cell transplants. The humanized mice, engineered to have a human-like immune system, failed to robustly reject genetically mismatched human stem cells, making them unsuitable for studying immunosuppressive drugs.

Hormonal tug-of-war helps plant roots navigate their journey through the soil

A sophisticated mechanism allows plant roots to quickly respond to changes in soil conditions via the interactions of two antagonistic hormones, auxin and cytokinin. Cells sense relative changes in auxin levels to determine their location within the root and trigger a switch from cell division to elongation.
