Re: What should be the big issues of the 2008 election?
As a complete outsider I don't think it's my place to suggest any big issues for the presidential candidates to deal with. However, there are some smaller issues on which I would find it very enlightening to hear the candidates opinions.
From a human rights perspective I would very much like to learn whether or not the candidates are planning to uphold the American Servicemembers protection act, not only because of the "The Hague invasion clause" embedded in that act, but also because it embodies the current stance of the United States of America to the ICC.
Another smaller issue on which I would like to hear the candidates point of view include their ideas about the trias politica, and the specific division of power between the executive, legislative and judicial branches, as that division seems to have become somewhat muddled lately.
At any rate I would like to hear less about the fact candidates wanting to restore the prestige of the USA and more about how they intend to do this.
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.
It's a "canary in the coalmine," said one climate scientist.
- 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.
One of Stephen Hawking's predictions seems to have been borne out in a man-made "black hole".
- 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.
Not every part of a satellite burns up in reentry. Considering the growing number of satellites in orbital space, that's a big problem.
- 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.
