Researchers Activate False Memories in the Brain
Using light to activate specific proteins in the brain which recall memories, scientists have found that just a few cells in the hippocampus can contain rich and powerful memories.
What's the Latest Development?
Scientists have found that by activating just a few brain cells in the hippocampus, the brain's memory center, strong memories can be released. MIT researchers first isolated brain cells in mice that were active only when experiencing a new environment, then gave the mice electric shocks. Using light to later activate these same brain cells in a neutral environment, the mice immediately cowered into a defensive crouch, suggesting they were recalling the experience of being shocked, though the memory had been artificially stimulated.
What's the Big Idea?
The experiment settles some old philosophical questions by confirming that ethereal phenomena like memory are actually contained within physical brain cells. "René Descartes didn’t believe the mind can be studied as a natural science. He was wrong. This experimental method is the ultimate way of demonstrating that mind, like memory recall, is based on changes in matter," said the study's co-author co-author Xu Liu. Scientist say the experiment may also have applications in the study of neurodegenerative and neuropsychiatric disorders.

The stories we tell define history. So who gets the mic in America?
- History is written by lions. But it's also recorded by lambs.
- In order to understand American history, we need to look at the events of the past as more prismatic than the narrative given to us in high school textbooks.
- Including different voices can paint a more full and vibrant portrait of America. Which is why more walks of American life can and should be storytellers.
There is no doubt that the historical Jesus, the man who was executed by the Roman State in the first century CE, was a brown-skinned, Middle Eastern Jew.
I grew up in a Christian home, where a photo of Jesus hung on my bedroom wall. I still have it. It is schmaltzy and rather tacky in that 1970s kind of way, but as a little girl I loved it. In this picture, Jesus looks kind and gentle, he gazes down at me lovingly. He is also light-haired, blue-eyed, and very white.
