Children's Laughter the Apex of Joy
The sound of children laughing delights listeners more than any other noise, a New Zealand study has found. Psychologist Aaron Jarden says it is because laughter is associated with well-being.
What's the Latest Development?
In a recent study out of New Zealand, people were asked which sounds they most closely associate with joy. At the top of the list was the sound of children laughing, followed by sounds of nature and animals. "I think that is purely an evolutionary mechanism in the sense that laughter is a sign that things are going well," says psychologist Aaron Jarden. He said picturing a baby evoked a feeling of well-being but adding the sound of laughter made it more potent. At the bottom of the list were armpit farts, V-8 engines and firecrackers.
What's the Big Idea?
How does the noise in our environment affect our well-being? The results of recent research indicate that our sense of joy plummets when we are surrounded by a dull hum or loud bursts of sound. "Jarden, the lead investigator in New Zealand for an international wellbeing survey, said regularly experiencing joy was a vital component in the wellbeing spectrum, along with positive emotion, engagement and meaning in life, positive relationships and accomplishment. 'Those are the five key areas, if you are topping those, and doing well in those, you will have wellbeing.'"
What can 3D printing do for medicine? The "sky is the limit," says Northwell Health researcher Dr. Todd Goldstein.
- Medical professionals are currently using 3D printers to create prosthetics and patient-specific organ models that doctors can use to prepare for surgery.
- Eventually, scientists hope to print patient-specific organs that can be transplanted safely into the human body.
- Northwell Health, New York State's largest health care provider, is pioneering 3D printing in medicine in three key ways.
Mega-rich entrepreneurs are taking us where no human being has gone before.
- During the first golden era of space exploration, we went to the moon. Then we sort of dropped the ball for 50 years.
- The problem is space travel is very expensive, especially the way governments do space travel.
- Because it costs $10,000 to put a pound of anything into orbit around the planet, we need to have an infusion of public and private funds. That's where billionaires such as Elon Musk and Jeff Bezos come into the picture. With their help, we have new energies, new strategies, and new plans to go back into outer space.
