Empathy and cooperation go hand in hand
Taking a game theory approach to study cooperation, School of Arts and Sciences evolutionary biologists find that empathy can help cooperative behavior ‘win out’ over selfishness.
Cells control their own fate by manipulating their environment
Muscle, blood, brain, and skin cells are different from one another, but they all share the same DNA. Stem cells’ transformation into specialized cells is controlled through various signals from their surroundings. A study suggests that cells may have more control over their fate than previously thought.
Answering big questions by studying small particles
Using electronics designed at Penn, particle physicists study neutrinos, incredibly small and nearly massless subatomic particles, to understand the fundamental nature of the universe.
Unlocking the female bias in lupus
The majority of lupus patients are female, and new findings from Montserrat Anguera of the School of Veterinary Medicine and colleagues shed light on why. The research suggests that female lupus patients don’t fully silence their second X chromosome in T cells, leading to an immune response gone awry.
