Mercury Poisoning Prevention (video from AOL.com)

Video – Some fish have levels of mercury so high that it may be harmful, especially for pregnant women and young children. Find out if you may have been exposed to mercury.

Remember these prevention tips.

Ask yourself:  If mercury poisoning is not a problem worthy of EPA’s new standards to prevent mercury pollution, why are health officials warning us to restrict our intake of fish that soak up the mercury emitted by coal-fired power plants?

 

[No, I can’t figure out why the video doesn’t show here.  Look at the VodPod widget in the right column, a bit lower, and look at the video there.  Or, click on the link, and go to the site with the video.]

News from NASA about a cool picture and feature on Mercury:

Rachmaninoff on Mercury

The International Astronomical Union (IAU) recently approved the name Rachmaninoff for an intriguing double-ring basin on Mercury. This basin, first imaged in its entirety during MESSENGER’s third Mercury flyby, was quickly identified as a feature of high scientific interest, because of its fresh appearance, its distinctively colored interior plains, and the extensional troughs on its floor. The basin’s name honors the Russian composer, pianist and conductor, Sergei Rachmaninoff (1873-1943).

IAU names craters on Mercury after “deceased artists, musicians, painters and authors who have made outstanding or fundamental contributions to their field and have been recognized as art historically significant figures for more than 50 years.” The process of proposing a new crater name includes gathering fundamental information about the crater, such as the crater’s central latitude, central longitude, and diameter. Justification is provided as to why the crater is of sufficient scientific importance to be named, and details are provided about the name choice, including sources that support the worthy contributions made by that individual. Ten newly named craters join 42 others named since MESSENGER’s first Mercury flybyin January 2008.
