Population science is more art than science so you can count on me to be a little skeptical. However, there are times when the numbers are just too alarming and we have to mobilize for action.

What is this looming population catastrophe? It's Elvis impersonators. Even the Center for Disease Control has sounded the alarm about this issue.  If the CDC is worried about an issue, so am I.

1) Exxon-Mobil = $16 million among 43 groups in the 8 years covering 1998 to 2005.
Dr Gavin Prideaux, paleontologist for Western Australian Museum and Flinders University, publishes an article in international journal Geology's January 2007 edition that is certain to fuel what has become one of palaeontology's longest-running and contentious debates.
The latest study is unique in providing a long-term perspective on the responses of the megafauna in the Naracoorte Caves region of south-eastern Australia to cyclical swings in Ice Age climates.
Australia lost 90% of its large fauna, including rhino-sized marsupials, 3-metre tall kangaroos and giant goannas within 20 thousand years of human arrival.

The longest-running search for radio signals from alien civilizations is getting a burst of new data from an upgraded Arecibo telescope, which means the SETI@home project needs more desktop computers to help crunch the data.

Since SETI@home launched eight years ago, the project based at the University of California, Berkeley's Space Sciences Laboratory has signed up more than 5 million interested volunteers and boasts the largest community of dedicated users of any Internet computing project: 170,000 devotees on 320,000 computers.

Yet, new and more sensitive receivers on the world's largest radio telescope in Arecibo, Puerto Rico, and better frequency coverage are generating 500 times more data for the project than before.

A breakthrough in understanding the way atoms move across cell membranes in the human body could pave the way for the development of new treatments for inflammatory diseases such as rheumatoid arthritis.

Scientists at the University of Leeds have identified a previously unknown natural mechanism that opens ion channels – proteins at the cell surface that act as doorways into and out of cells – through the naturally occurring protein thioredoxin.

Ion channels allow movement of ions - electrically charged atoms - across the cell membrane to carry out various functions such as pain transmission, timing of the heart beat, and regulation of blood glucose.

Russians, Americans and Chi-Coms all squared off against each other. Organized deception, intrigue, insults, reclusive personalities ... another day in international politics? Not this time. It's mathematicians. You think physicists are strange?   Try to figure out mathematicians some time.*

It starts with a bit of mathematical fluff called the Poincaré conjecture, encompasses certifiable silliness in the name of string theory and ends with a million dollars. You just don't get more intrigue than that.
