Re What will our hospital system look like when the last baby boomers retire?

Question: What will our hospital system look like when the last baby boomers retire?

Robert Butler: In the first place, I think we shouldn't have this many people in the hospitals. I think we can do much more outpatient care and we have already seen that happen quite wonderfully. I mean cataracts are now like an hour in the outpatient department and then to your home. So, I think we are going to have to do much more care that keeps people at home and not in the hospital.

Robert Butler: They better go to work on their diets. Since the reason this is the fattest country in the world is because of the baby boomers. They are fat and they are still smoking, at least half of them are and they aren’t saving their money and they are not exercising despite the notion that baby boomers that are out there are physically exercising, they are really not. So, they have a lot to do and they could do it, but it is going to be tough for them to suddenly change their lives [Inaudible] the oldest ones, 12,000 [Inaudible] that will become 62 today.

We can do a lot more, Butler says, with outpatient care.

How to make a black hole

Here's the science of black holes, from supermassive monsters to ones the size of ping-pong balls.

  • There's more than one way to make a black hole, says NASA's Michelle Thaller. They're not always formed from dead stars. For example, there are teeny tiny black holes all around us, the result of high-energy cosmic rays slamming into our atmosphere with enough force to cram matter together so densely that no light can escape.
  • CERN is trying to create artificial black holes right now, but don't worry, it's not dangerous. Scientists there are attempting to smash two particles together with such intensity that it creates a black hole that would live for just a millionth of a second.
  • Thaller uses a brilliant analogy involving a rubber sheet, a marble, and an elephant to explain why different black holes have varying densities. Watch and learn!
  • Bonus fact: If the Earth became a black hole, it would be crushed to the size of a ping-pong ball.

Project 100,000: The Vietnam War's cruel and deadly experiment

Military recruits are supposed to be assessed to see whether they're fit for service. What happens when they're not?

  • During the Vietnam War, Robert McNamara began a program called Project 100,000.
  • The program brought over 300,000 men to Vietnam who failed to meet minimum criteria for military service, both physically and mentally.
  • Project 100,000 recruits were killed in disproportionate numbers and fared worse after their military service than their civilian peers, making the program one of the biggest—and possibly cruelest—mistakes of the Vietnam War.

China’s artificial sun reaches fusion temperature: 100 million degrees

In a breakthrough for nuclear fusion research, scientists at China's Experimental Advanced Superconducting Tokamak (EAST) reactor have produced temperatures necessary for nuclear fusion on Earth.

Surprising Science
  • The EAST reactor was able to heat hydrogen to temperatures exceeding 100 million degrees Celsius.
  • Nuclear fusion could someday provide the planet with a virtually limitless supply of clean energy.
  • Still, scientists have many other obstacles to pass before fusion technology becomes a viable energy source.
