The Next Global Pandemic: Mental Health

Posted by in categories: biotech/medical, health, neuroscience

What if the next global health crisis is a mental health pandemic? It is here now.

According to Gallup, anger, stress, worry and sadness have been on the rise globally for the past decade — long before the COVID-19 pandemic — and all reached record highs in 2020.

People die from COVID-19 — they also die from depression and anxiety disorders. The U.S. has seen spikes in deaths from suicide and “deaths of despair.”

New Brain Maps Can Predict Behaviors

Posted by in categories: mapping, neuroscience

Rapid advances in large-scale connectomics are beginning to spotlight the importance of individual variations in the neural circuitry. They also highlight the limitations of “wiring diagrams” alone.

Sean Carroll: Is Consciousness Emergent?

Posted by in categories: cosmology, neuroscience, physics

Theoretical physicist Sean Carroll joins us to discuss whether it make sense to think of consciousness as an emergent phenomenon, and whether contemporary physics points in this direction.

We discussed Sean’s essay responding to Philip’s book ‘Galileo’s Error,’ and Philip’s counter-response essay. Both are available here:

These gorgeous images could transform science education

Posted by in categories: biotech/medical, education, neuroscience, science

Science isn’t all lab coats and test tubes. Beautiful visuals can engage people—especially students—and inspire them to learn about science more broadly.

Scientists have often invited the public to see what they see, using everything from engraved woodblocks to electron microscopes to explore the complexity of the scientific enterprise and the beauty of life. Sharing these visions through illustrations, photography, and videos has allowed laypeople to explore a range of discoveries, from new bird species to the inner workings of the human cell.

This Ingenious Technique Helped Scientist to ‘Read Minds’ of Jellyfish

Posted by in categories: food, neuroscience

Scientists have found a way to interpret jellyfish’s thoughts regardless of not having any neurons, study finds.

They were able to observe how well the cells in a tiny type of see-through jellyfish operate collectively, to produce complicated independent motions, such as capturing and consuming food source. This is all thanks to ingenious molecular manipulation.

Karl Deisseroth: Optogenetics, Psychiatry, Emotion, Autism, Dissociation & “Projections” | #35

Posted by in categories: genetics, neuroscience

Nick talks to Stanford psychiatrist and neuroscientist Dr. Karl Deisseroth. They discuss a range of topics about the brain, including autism, depression, bipolar disorder, dissociation, and more. They also talk about optogenetics, a technique Karl co-developed which uses light to control specific neurons in the brain, allowing neuroscientists to turn circuits in the brain on and off to reveal how the brain generates perception, emotion, and behavior. They also talk about Karls’ new book, “Projections: A Story of Human Emotion.”

Can Science Survive the Death of the Universe?

Posted by in categories: biotech/medical, climatology, cosmology, ethics, neuroscience, particle physics, science, sustainability

Let me back up a moment. I recently concurred with megapundit Steven Pinker that over the last two centuries we have achieved material, moral and intellectual progress, which should give us hope that we can achieve still more. I expected, and have gotten, pushback. Pessimists argue that our progress will prove to be ephemeral; that we will inevitably succumb to our own nastiness and stupidity and destroy ourselves.

Maybe, maybe not. Just for the sake of argument, let’s say that within the next century or two we solve our biggest problems, including tyranny, injustice, poverty, pandemics, climate change and war. Let’s say we create a world in which we can do pretty much anything we choose. Many will pursue pleasure, finding ever more exciting ways to enjoy themselves. Others may seek spiritual enlightenment or devote themselves to artistic expression.

No matter what our descendants choose to do, some will surely keep investigating the universe and everything in it, including us. How long can the quest for knowledge continue? Not long, I argued 25 years ago this month in The End of Science, which contends that particle physics, cosmology, neuroscience and other fields are bumping into fundamental limits. I still think I’m right, but I could be wrong. Below I describe the views of three physicists—Freeman Dyson, Roger Penrose and David Deutsch—who hold that knowledge seeking can continue for a long, long time, and possibly forever, even in the face of the heat death of the universe.
