Television Wars

Blogger Jeff Jarvis wades into the television fight by suggesting that Cablevision customers switch to the “better service” Verizon Fios—but that doesn’t mean he’s siding with ABC!

Blogger Jeff Jarvis wades into the television fight by suggesting that Cablevision customers switch to the "better service" Verizon Fios—but that doesn’t mean he’s siding with ABC! He says: "[ABC]—like Fox before them—are trying to get us to pay for free TV channels. This was a point I wanted to make at last week’s FCC workshop on the future of media: It’s no longer true that broadcast channels are free. Fewer than 13% of Americans get broadcast channels over the air; the rest of us have to pay for cable or satellite to get access and now these channels—which got our spectrum for free—are trying to charge us yet more. Who’s fighting for us? Not the FCC. But I think that as these fees are fought over and granted to broadcast channels and passed on to viewers—adding up to a likely $72 for New York’s half-a-dozen commercial channels—then I still think that there will be a consumer revolt and the FCC will have the cause it seems to have wanted to require a la carte pricing for cable. Then both broadcasters and cable operators and their parent companies will get their just desserts. I will not pay for 90 percent of the channels I am forced to pay for now. That will reduce revenue to cable. It will mean that many channels will no longer be subsidized. It will kill marginal channels."

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.
