CalTech Scientists Test World Cup Ball and a U.S. Prediction

You have to like the U.S. chances in advancing to the semi-finals of the World Cup. That's right, the semi-finals. If the U.S. beats Ghana on Saturday--and they should be a favorite--they play the winner of Uruguay and S. Korea in the quarterfinals.

Meanwhile, readers will find interesting this video from Reuters featuring CalTech scientists testing the controversial "Jabuluani" ball used at the World Cup.

What do you think? Like the U.S. chances to make the semis? Has the ball had an impact on the games?

3D printing might save your life one day. It's transforming medicine and health care.

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.

Permafrost is melting 70 years earlier than expected in Arctic Canada

It's a "canary in the coalmine," said one climate scientist.

Surprising Science
  • A team of researchers discovered that permafrost in Northern Canada is melting at unusually fast rates.
  • This could causes dangerous and costly erosion, and it's likely speeding up climate change because thawing permafrost releases heat-trapping gasses into the atmosphere.
  • This week, Canada's House of Commons declared a national climate emergency.

Has a black hole made of sound confirmed Hawking radiation?

One of Stephen Hawking's predictions seems to have been borne out in a man-made "black hole".

Surprising Science
  • Stephen Hawking predicted virtual particles splitting in two from the gravitational pull of black holes.
  • Black holes, he also said, would eventually evaporate due to the absorption of negatively charged virtual particles.
  • A scientist has built a black hole analogue based on sound instead of light.

Watch scientists melt a satellite part to save us from space junk

Not every part of a satellite burns up in reentry. Considering the growing number of satellites in orbital space, that's a big problem.

Technology & Innovation
  • Earth's orbital space is getting more crowded by the day.
  • The more satellites and space junk we put into orbit, the greater a risk that there could be a collision.
  • Not all materials burn up during reentry; that's why scientists need to stress test satellite parts to ensure that they won't become deadly falling objects.
