Researchers have unravelled a genetic puzzle that explains why black sheep have become a dying breed on one Scottish island.

They say the findings suggest natural selection can act on single-gene traits like coat colour in a way that's more complex than generally thought.

The Black Death that decimated populations in Europe and elsewhere during the middle of the 14th century may not have been a blindly indiscriminate killer as previously believed.

An analysis of 490 skeletons from a London cemetery for Black Death victims shows the infection did not affect everyone equally, researchers say.

Jan. 25, 2008 -- Well water of the tiny Canadian town of Gypsumville, Manitoba (population 65) has been poisoned by an extraterrestrial.

The invader: A meteorite which struck down almost a quarter-billion years ago, creating the 25-mile-wide (40-kilometer) Lake Martin impact crater.

Albuquerque, N.M. - An asteroid that exploded over Siberia a century ago, leaving 800 square miles of scorched or blown down trees, wasn't nearly as large as previously thought, a researcher concludes, suggesting a greater danger for Earth.

Washington, D.C. - A young star is speeding away from the Milky Way so fast that astronomers have been puzzled by where it came from; based on its young age it has traveled too far to have come from our galaxy. Now by analyzing its velocity, light intensity, and for the first time its tell-tale elemental composition, Carnegie astronomers Alceste Bonanos and Mercedes López-Morales, and collaborators Ian Hunter and Robert Ryans from Queen's University Belfast have determined that it came from our neighboring galaxy, the Large Magellanic Cloud (LMC). The result suggests that it was ejected from that galaxy by a yet-to-be-observed massive black hole. The research will be published in an upcoming issue of the Astrophysical Journal Letters.

As vulnerable as naked mole rats seem, researchers now find the hairless, bucktoothed rodents are invulnerable to the pain of acid and the sting of chili peppers.

A better understanding of pain resistance in these sausage-like creatures could lead to new drugs for people with chronic pain, scientists added.

Even though it is sensitive to touch, the naked mole rat doesn't even flinch when inflicted with burning acid.

ESA's Cluster mission has, for the first time, observed the extent of the region that triggers magnetic reconnection, and it is much larger than previously thought. This gives future space missions a much better chance of studying it.

On January 5, 2008, Project Camelot first released their ground a breaking 2012 disclosure by a well-placed Norwegian Politician. In it, he describes a massive network of deep underground survival bases.

This morning I was thumbing through a newly arrived book: Comet/Asteroid Impacts and Human Society, published by the eminent scientific publishing house, Springer, edited by Peter T. Bobrowsky and Hans Rickman. This book is a collection of scientific papers presented at a workshop under the aegis of the International Council for Science. In the introduction, we read:

The International Council for Science recently recognized that the societal implications (social, cultural, political and economic) of a comet/asteroid impact on Earth warrants an immediate consideration by all countries in the world.

Wow! You think? You mean it's not just us here at SOTT (and a few others on the net) who are keeping track of the increasing number of Fireballs and Meteorites that suggest we are passing through rather dangerous areas of space, or that maybe Something Wicked This Way Comes?

Yes, it seems so. In the chapter entitled "Social Perspectives on Comet/Asteroid Imact (CAI) Hazards: Technocratic Authority and the Geography of Social Vulnerability" we read:

Until quite recently, research into comet and asteroid hazards was focused on establishing the scale and scope of past impacts, credible estimates of their recurrence, and models for physical impact scenarios. ... CAI hazards have moved well beyond the realm of ungrounded speculation and apocalyptic visions. The results represent more than just new findings. They revolutionize, or are about to revolutionize, some basic understandings about the Earth, its history, biological evolution and future. Although human life has had a tiny place in the story so far, our longer term fate seems to be challenged by these forces and may be decided by them.

No kidding.

In a chapter entitled "Social Science and Near-Earth Objects: an Inventory of Issues", we read:

It would have been ridiculous, not too long ago, to admit openly that you were thinking about asteroids and comets slamming into the Earth. Such events could mean the end of the world as we know it - TEOTWAWKI as millenialists call it - and that kind of talk is often ridiculed. ...

Respectable people are pondering the issues. For example, S. Pete Worden, who is a Brigadier General in the US Air Force and Deputy Director for Command and Control Headquarters at the Pentagon, has said that he believes "we should pay more attention to the 'Tunguska-class' objects - 100 meter or so objects which can strike up to several times per century with the destructiveness of a nuclear weapon."

I located the General's comments and they are now in the SOTT database. It seems that the above is not all the general said. In fact, he states quite unequivocally:

I can show people evidence of real strikes inflicting local and regional damage less than a century ago. Even more compelling are the frequent kiloton-level detonations our early warning satellites see in the earth's atmosphere. ... Within the United States space community there is a growing concern over "space situational awareness."

The general was writing back in 2000. "Less than a century ago." That would be after 1900. He said that there were "real strikes inflicting local and regional damage" since 1900?!

Did I miss something? Did all of us miss something?

During four months prior to the fourth anniversary of its landing on Mars, NASA's Mars Exploration Rover Opportunity examined rocks inside an alcove called "Duck Bay" in the western portion of Victoria Crater.

The main body of the crater appears in the upper right of this panorama, with the far side of the crater lying about 800 meters (half a mile) away. Bracketing that part of the view are two promontories on the crater's rim at either side of Duck Bay.
