How to Reverse Aging

Enzymes like Telomerase and Resveratrol, though not the Fountain of Youth unto themselves, offer tantalizing clues to how we may soon unravel the aging process.

Every Wednesday, Michio Kaku will be answering reader questions about physics and futuristic science. If you have a question for Dr. Kaku, just post it in the comments section below and check back on Wednesdays to see if he answers it.


Today, Dr. Kaku addresses a question posed by Paul Cellura: Do you think the enzyme Telomerase could be used to reverse the aging process in our lifetime?

Plants have awareness and intelligence, argue scientists

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

Surprising Science
  • The field of plant neurobiology studies the complex behavior of plants.
  • Plants were found to have 15-20 senses, including many like humans.
  • Some argue that plants may have awareness and intelligence, while detractors persist.

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 be 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.
