You are gazing over the clear stream, thinking of fishing the crystal waters in the Rockies. The next morning, you are stunned to see an orange-yellow sludge covering the stream as far as you can see. Is this the Colorado Gold King Mine spill into Cement Creek of August 5, 2015?

No, this describes the Clear Creek, CO spill of April, 2009 from a private mine or it could be the 1975 or 1978 Cement Creek spills from abandoned mines.

New species evolve whenever a lineage splits off into several branches and so a common metaphor for evolution has been to describe evolution as a 'tree of life', where every branch constitutes a species.

But since about 99.999% of all species that have ever existed are already extinct, and we have never even known about them, the tree is more like a bush with things constantly growing and falling off. Last year, a consortium of some hundred researchers reported that the relationship between all major bird clades had been mapped out by analyzing the complete genome of around 50 bird species. This included the exact order in which the various lineages had diverged.

Both donors and recipients want more information about each others' health before participating in transplant surgeries, according to a study which challenges current practices and policies on information disclosure for prospective living kidney donors and their intended recipients..

For students, the start of the school year means new classes, new friends, homework and sports. It also brings the threat of head lice. The itch-inducing pests lead to missed school days and frustrated parents, who could have even more reason to be wary of the bug this year. Scientists report that lice populations in at least 25 states have developed resistance to over-the-counter treatments still widely recommended by doctors and schools.

The researchers are presenting their work today at the 250th National Meeting&Exposition of the American Chemical Society (ACS), the world's largest scientific society. The meeting features more than 9,000 presentations on a wide range of science topics and is being held here through Thursday.

My wife and I went to see Big Bad Voodoo Daddy (“You and Me and the Bottle Makes Three”) Saturday at Conner Prairie, part of the Indianapolis Symphony Orchestra Symphony on the Prairie summer series. We got there a bit early and ended up sweating in the hot, hot sun waiting for the concert to start.

It used to be that clean energy was something that environmental lobbyists pretended to care about, at least when it came to raising money.  Greenpeace, NRDC, you name it, they all put clean energy in their tool chest of ways to get their hundreds and hundreds of millions of dollars in the bank.

Of course, they never actually built anything to help us get clean energy, just like they don't do any science and instead prefer to criticize those who know what they're talking about. They just embrace whatever isn't shown to be viable and abandon efforts that succeed, as they did with ethanol and natural gas after they got the uptake they insisted was needed.
