Inventions of the Future

Question: What are some futuristic inventions that we’ll see In our lifetime?

Michio Kaku: So you ask a simple question. Invisibility: just decades away we will have something resembling Harry Potter’s invisibility cloak. 

Something equally astonishing is shape-shifting.  When you see science fiction movies like "Terminator II" and you see the evil robot turn into jelly and then ooze its way through obstacles, you say to yourself "No way, no way can that happen."  Believe it or not, we scientists are making huge inroads into that area.  It’s called programmable matter.  Matter itself that can rearrange itself, change color, change shape, change conductivity by pushing a button. And here is how it works: Why is it that certain substances can turn liquid and ooze its way across the room like in the movie "Terminator II?"  It’s because of atoms.  Atoms can slide over atoms, rearrange themselves, but what happens if atoms are replaced by chips, chips that are so small they’re smaller than the head of a pin. And you can change their electric charge.  By changing the electric charge they bind and reform in different ways and they’re intelligent because each dot is a computer chip perhaps as powerful as a PC.  These are called catoms and who is pushing this technology?  The Intel Corporation, the makers of the famous Pentium chip that drives your laptop.  The same company is now investigating the next several steps in the future, the ability to have programmable matter. 

Now think about it.  It means that if I have a clump of clay made of thousands of millions of little dots I push a button then the charges rearrange themselves to form a statue, a car, whatever you want.  This means that I can push another button and this clay turns into a house or I push another button and a whole city, a whole city rises out of the desert.  Sounds like science fiction, but the basic steps are being done today. And in fact, with a television crew I went to Carnegie Mellon University in Pittsburgh and photographed it.  Of course these catoms are quite large.  They’re about the size of a head of a pin, but it’s only a matter of time before these catoms become so microscopic and so powerful that they’ll be able to rearrange just like what you see in "Terminator II," just like what you see in the "Transformers," just like what you see in X-men comics.

The physicist believes that shape-shifting technology is near on the horizon. And "just decades away we will have something resembling Harry Potter’s invisibility cloak."

Can the keto diet help treat depression? Here’s what the science says so far

A growing body of research shows promising signs that the keto diet might be able to improve mental health.

Mind & Brain
  • The keto diet is known to be an effective tool for weight loss, however its effects on mental health remain largely unclear.
  • Recent studies suggests that the keto diet might be an effective tool for treating depression, and clearing up so-called "brain fog," though scientists caution more research is necessary before it can be recommended as a treatment.
  • Any experiments with the keto diet are best done in conjunction with a doctor, considering some people face problems when transitioning to the low-carb diet.

A world map of Virgin Mary apparitions

She met mere mortals with and without the Vatican's approval.

Strange Maps
  • For centuries, the Virgin Mary has appeared to the faithful, requesting devotion and promising comfort.
  • These maps show the geography of Marian apparitions – the handful approved by the Vatican, and many others.
  • Historically, Europe is where most apparitions have been reported, but the U.S. is pretty fertile ground too.
