Super Laser

QUEST visits the National Ignition Facility in Livermore, where scientists will soon aim the world’s largest laser at a target the size of a pencil eraser. The goal? Nuclear fusion — and, they say, the answer to the world’s clean energy needs.

Expelled Exposed: But Wait, There’s More!

I’ve already announced to you, twice, the emergence of a new web site called “Expelled Exposed” developed by the National Center for Science Education. Chances are you already went and looked at the site.But, as of a few minutes ago, the site has been totally refined and updated. The site that is now up at www.expelledexposed.com is presumably the intended product, and it is quite different from, more extensive, more informative, fancier, than the earlier site.

It is said that he was giving a talk on the phenomenon, and during the talk a student called out “black hole” as a suggested name for the phenomenon, and it stuck.

Elephants Were Aquatic

ResearchBlogging.orgThat elephants have an aquatic ancestry has been suspected for some time now. Moreover, the idea of elephant aquatic origins and elephant origins in general is part of a growing realization that many of the world’s aquatic mammals originated in a couple of regions of Africa that were for a very long time enormous inland seas (but that is another story I won’t cover here).i-6c35376f2760f31203073fcad7f65c38-elephant_baby_kruger.jpgThe earlier evidence came from observation of the ontogeny of the kidneys in elephants, during which the kidneys take on the characteristics that are found in aquatic mammals generally. That research was published in 1999, and is summarized here: Continue reading Elephants Were Aquatic
