Blood Mystery Solved

RBC Compatibility chart In addition to donatin...Image via WikipediaBlood Mystery Solved: You probably know your blood type: A, B, AB or O. You may even know if you're Rhesus positive or negative. But how about the Langereis blood type? Or the Junior blood type? Positive or negative? Most people have never even heard of these. Yet this knowledge could be "a matter of life and death," says University of Vermont biologist Bryan Ballif.

While blood transfusion problems due to Langereis and Junior blood types are rare worldwide, several ethnic populations are at risk, Ballif notes. "More than 50,000 Japanese are thought to be Junior negative and may encounter blood transfusion problems or mother-fetus incompatibility," he writes.

But the molecular basis of these two blood types has remained a mystery - until now.

In the February issue of Nature Genetics, Ballif and his colleagues report on their discovery of two proteins on red blood cells responsible for these lesser-known blood types.

Is Another Mass Extinction Event on the Way?

English: K/T extinction event theory. An artis...Image via WikipediaIs Another Mass Extinction Event on the Way?: Why have mass extinctions of species occurred since the late Proterozoic (from 580 million years ago) and repeatedly through the Phanerozoic? Integral to these extinctions were abrupt changes in the physical and chemical properties of the atmosphere, ocean and land, inducing environmental changes at a pace to which many species could not adapt.

The best documented example to date is the 65 million years-old K-T boundary asteroid impact and extinction event. But several other mass extinctions were associated with volcanic eruptions and asteroid/comet impacts (see Figure 1).

Instantaneous effects of impacts (initial fireball flash as the asteroid or comet enters the atmosphere, crater explosion, seismic shock, tsunami waves, incandescent ejecta, dust plumes, greenhouse gas release from carbon-rich limestone and shale) occurred over periods ranging from seconds to weeks and months.

As shown in figure 1, Phanerozoic history (since about 540 million years ago) is marked with a number of mass extinction events. About 80% of genera were lost at the ~251 Ma Permian-Triassic boundary event. This was a consequence of both volcanic eruptions (known as the Siberian Norilsk traps) and an asteroid impact near Araguinha, Brazil (Araguinha: 40 km-diameter; 252.7+/-3.8 Ma).

Family of three die from apparent starvation in Japan

Discovery raises questions over the official response to rising poverty levels among the elderly and the unemployed in Japan

Authorities in Japan are under pressure to explain how three members of the same family were allowed to die of apparent starvation, after their bodies were discovered two months after their deaths.
Police found the bodies of a couple believed to be in their 60s and their son, thought to be in his 30s, at their apartment in Saitama, north of Tokyo, after the building's owner said he had been unable to contact them.

P.702 - §7 The ice age is the last completed geologic period, the so-called Pleistocene, over two million years in length.

P.702 - §8 35,000 years ago marks the termination of the great ice age excepting in the polar regions of the planet. This date is also significant in that it approximates the arrival of a Material Son and Daughter and the beginning of the Adamic dispensation, roughly corresponding to the beginning of the Holocene or postglacial period.

America's Shrinking Corporate Giants

America's Shrinking Corporate Giants:

This post originally appeared at 24/7 Wall St.

It is rare for one of America’s largest companies to lose a third or more of its sales in a brief time. When it happens, it is usually either because of market or economic forces, or because of a designed refocusing. 24/7 Wall St. identified the eight largest American companies whose revenue fell the most in the past five years and analyzed the reasons behind the drops.
