Finding the "Cancer Beacon" That Immune Cells Recognize

When the body’s immune system fights cancer, how does it choose a specific target? Researchers from the Howard Hughes Medical Institute Investigator (HHMI) have spent decades studying the molecular structure of the immune system in an effort to answer this question. In December 2017, they reported a screening method that allowed them to identify which “signals” displayed by cancer cells were being recognized by the immune system, effectively discovering a “cancer beacon.”

How a Social Robot Helped Kids Fight Less

Many adults have tried to help kids argue less, perhaps as parents or teachers. If not, they have certainly been a kid and likely remember a few “conflict-resolution challenges" from their own youth. Researcher Solace Shen and her colleagues from Cornell University and University College London carried out an experiment examining if a remotely-controlled social robot might be able to help young people resolve disagreements over toys. They found that the robot they used, called “Keepon,” could do just that.

How Virtual Reality Is Used to Explore Empathy at Stanford, With Reflections from VHIL Director Jeremy Bailenson (PDF in new tab)

Virtual Reality (VR) may bring to mind advanced gaming possibilities and simulated, entertaining, sensory experiences. The team at Stanford University’s Virtual Human Interaction Lab (VHIL) is using VR in an innovative way: to teach and explore human empathy. They create immersive experiences in which learners virtually become a different person or even a member of a different species, and they are discovering that VR can powerfully affect and formulate our world views and behavior.
