Researchers at Washington University have genetically-engineered cells to react to light.
By taking light-sensing receptors from the eye — called opsins — and inserting them into immune cells, the researchers were able to trick the cells into moving toward a laser beam, in the same way they would move toward a bacterial infection.
Washington University molecular biologist N. Gautam led the research.
In 2005, President Bill Clinton established the Clinton Global Initiative (CGI). The goal of the ongoing project is to “create and implement innovative solutions to the world's most pressing challenges.”
For many years, it’s been thought that Stonehenge, the ancient monolith in southwestern England, was created by Druids around 460 B.C.
New research shows that is incorrect. “Even today, a lot of people think Stonehenge is connected to Druids. We are very certain from radon carbon dating that it happened before,” said British archaeologist Mike Parker Pearson, Professor at the Institute of Archaeology, University College London and leader of the Stonehenge Riverside Project.
