Libyan Desert Glass
is strewn over an area of hundreds of square kilometers in the Great Sand Sea, a region desolate even by the high standards of the Sahara. As one account of a recent trip to acquire Libyan Desert Glass
puts it: "Out there, death sits on your shoulder like a vulture." While some would have you believe that Libyan Desert Glass is evidence of ancient atomic warfare, it is probably evidence
of a massive meteorite or comet explosion nearly thirty million years ago
, similar to Tunguska, but much bigger. The stone age Aterian peoples made tools
from it, but the remoteness and inhospitality of the Great Sand Sea has ensured that until recent times it has mostly been undisturbed. However, a breast ornament buried in Tutankhamen's tomb
has a scarab made from Libyan Desert Glass, the only piece made of the material to have been found by Egyptologists, and how Tutankhamen's jewelers acquired it has remained a mystery
. Until now

The nuclear weapons simulator
at CarlosLabs (previously)
has been updated to include fallout wind drift, pressure and thermal events to evaluate the impact of everything from a suitcase nuke to the Tsar Bomba
on your city. The Missile Range Tool
can show if you are in the vicinity of any delivery systems currently in service, or compare your location to the range of those used historically, such as the V2. For the effects of the cosmic collisions of asteroids and comets (and featuring rather more science) there's the Earth Impact Effects Program

What is the future of online news.
Will subscription eventually win through? Is there a viable business model that will allow independent publishers (such as Salon) to survive, or will we see further media consolidation? Where does blogging fit into this spectrum?

The stuff from which Myth is made.
A recent discovery of a meteor impact crater in the middle-east, dating around 2300BC, is shedding new light on the decline of many cultures and the rise of many legends.

Armageddon in 30 years?
Okay, so maybe hyped up a bit, but there's a 1:500 chance that whatever's out there might hit us. For now scientists don't know if it's really an asteroid, or just some leftover shuttle parts. [via SlashDot]
