Training Your Brain

A new way to create and interpret real-time brain scans could help addicts consciously control their cravings by making them aware of how their brain is functioning.

Technology might not be advanced enough yet to let people read someone else's mind, but researchers are at least inching closer to helping people to read and control their own. In a study presented last week at the Society for Neuroscience meeting in San Diego, scientists used a combination of brain-scanning and feedback techniques to train subjects to move a cursor up and down with their thoughts. The subjects could perform this task after just five minutes of training. The scientists hope to use this information to help addicts learn to control their own brain states and, consequently, their cravings.

Plants have awareness and intelligence, argue scientists

Research in plant neurobiology shows that plants have senses, intelligence and emotions.

Human extinction! Don't panic; think about it like a philosopher.

Most people think human extinction would be bad. These people aren't philosophers.

  • A new opinion piece in The New York Times argues that humanity is so horrible to other forms of life that our extinction wouldn't be all that bad, morally speaking.
  • The author, Dr. Todd May, is a philosopher who is known for advising the writers of The Good Place.
  • The idea of human extinction is a big one, with lots of disagreement on its moral value.

Space is dead: A challenge to the standard model of quantum mechanics

Since the idea of locality is dead, space itself may not be an aloof vacuum: Something welds things together, even at great distances.

  • Realists believe that there is an exactly understandable way the world is — one that describes processes independent of our intervention. Anti-realists, however, believe realism is too ambitious — too hard. They believe we pragmatically describe our interactions with nature — not truths that are independent of us.
  • In nature, properties of Particle B may depend on what we choose to measure or manipulate with Particle A, even at great distances.
  • In quantum mechanics, there is no explanation for this. "It just comes out that way," says Smolin. Realists struggle with this because it would imply certain things can travel faster than light, which still seems improbable.
