Too bad natural gas is trading about what it was in 1980 (largely from lot of new supply from fracking), and about 60% below its peak in 2009 - at least in the US [1]. Although prices in Japan are about 5X higher [2] 1 - http://www.eia.g

I believe that there are UV-resistant (sunlight) treatments for ABS. Many polymers (plastics) are vulnerable to UV light, but are still used in outdoor environments without major ill effects. And yes, my earlier implication was that it is

ABS plastic is a very common hard plastic. Its the stuff used in Lego bricks [1], for instance. [1] http://en.wikipedia.org/wiki/Acrylonitrile_butadiene_styrene

The title is extremely misleading, as the structural parts of the car are meant to be made of a metal tube frame, quote from article: "The design puts a tubular metal cage around the driver, “like a NASCAR roll cage,” Kor claims. And he als

Interesting, but not as new as they'd like you to think (article below from 2004, and the article mentions organ printing first being mentioned in 1999). http://www.ncbi.nlm.nih.gov/pubmed/12679063 Tissue engineering has been the "next bi

Seems a bit pre-mature for the conclusions of this article. The article is motivated by the grounding of the plane due to battery issues, but its not yet clear what is causing these batteries problems. In otherwords, the article's argumen

Can't comment on USA - in Canada we had an intro in high school then about a 1/2 course-credit module per year from second year until grad school in the engineering programs.

There are two problems with this article. First is that the "evidence" is from a scatter plot graph, with no statistical measurements attached to it. Stats really aren't something that you can rely on your eyes on. To me, it looks like a w

Original press release here, but it doesn't mention HIV http://www.ibn.a-star.edu.sg/images/cms_press/press_82.pdf My interpretation is that the hyrdagel-based "nanomeds" have the main advantage that they break-up biofilm colonies, which

One option would be non-alias usernames. Youtube seems to think this is the answer to poor-quality comments there, although I can see benefit for some HN posts being anonymous. The world is a tough place and life is too short to get worn d

I agree that his Special Relativity work was probably worked on with some contribution of Marić, but I think his later work was more individual. Others may deserve credit for some of it though http://en.wikipedia.org/wiki/Relativity_prior

I'm glad I searched before posting something similar. General Relatively is one of the greatest individual efforts in the history of science. I do think there is something noble about the self-isolation and dedication to his work that Ein

The snake example is good, but for me it is more intuitive to think of the z-y plane as having very small volume but infinite surface area as the plane extends infinately in both z and y.
