The Unconscious: Freud's Gift to Neuroscience
The idea that there's this massive amount happening under the hood came from Freud.
The history of understanding that there is an unconscious that’s riding under the radar of conscious awareness is such a new idea, historically. Several hundred years ago, people got pieces and parts of the idea, but it wasn't until Freud that he really nailed it.
Neuroscience has drifted off a little bit from the directions that Freud was going in terms of the interpretations of whether your unconscious mind is sending you particular hidden signals and so on. But the idea that there's this massive amount happening under the hood, that part was correct and so Freud really nailed that. And he lived before the blossoming of modern neuroscience, so he was able to do this just by outside observation and looking at how people acted.
Nowadays, we’re able to peer noninvasively inside people's heads as they're doing tasks, as they're thinking about things and making decisions, perceiving the world. We’re able to go a lot deeper into understanding this massive machinery under the hood.

What can 3D printing do for medicine? The "sky is the limit," says Northwell Health researcher Dr. Todd Goldstein.
- Medical professionals are currently using 3D printers to create prosthetics and patient-specific organ models that doctors can use to prepare for surgery.
- Eventually, scientists hope to print patient-specific organs that can be transplanted safely into the human body.
- Northwell Health, New York State's largest health care provider, is pioneering 3D printing in medicine in three key ways.
Torn between absolutism on the left and the right, classical liberalism—with its core values of compassion and incremental progress whereby the once-radical becomes the mainstream—is in need of a good defense. And Adam Gopnik is its lawyer.

The lost practice of face-to-face communication has made the world a more extreme place.
- The world was saner when we spoke face-to-face, argues John Cameron Mitchell. Not looking someone in the eye when you talk to them raises the potential for miscommunication and conflict.
- Social media has been an incredible force for activism and human rights, but it's also negatively affected our relationship with the media. We are now bombarded 24/7 with news that either drives us to anger or apathy.
- Sitting behind a screen makes polarization worse, and polarization is fertile ground for conspiracy theories and fascism, which Cameron describes as irrationally blaming someone else for your problems.
