How African Feminism Changed the World

'Feminism' has often been seen as a Western concept, but African women are increasingly redefining it to suit their own purposes. This, in turn, is influencing the rest of the world.

Mars: Cosmic Bullseye?

Will Mars be rocked by a massive comet in 2014? Maybe a little. Maybe a lot. A comet will definitely pass close to the Red Planet on October 19, 2014. [more inside]

Solid Sunlight

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. [Previously]

påske-krim

How do you write crime fiction in the wake of a massacre? The mass slaughter on Utøya in July shook Norway to its core. Now the country's crime writers must come to terms with what happened…

"FUBAR" cannot be expressed as a numeric output

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.

At least Michael Bay won't be directing...

In the year 2182 -- 172 years time -- there's a 1 in 1000 chance that we might be hit by a very large asteroid. With two centuries advance notice, will we be able to develop effective asteroid deflection techniques? [more inside]

Jupiter is a Large Target

Early this morning, local time, two amateur astronomers independently captured images of something colliding with Jupiter. Anthony Wesley (cache) in Broken Hill, Australia noticed it first. Wesley spread the word and Christopher Go (cache) in Cebu City, Philippines also found that he'd documented the event, which occurred at 20:31 June 3, Universal Time. [more inside]

Jupiter under fire

Sunday morning amateur astronomer Anthony Wesley captured a photo of an apparent asteroid or comet strike on Jupiter. Alerted by the announcement on the ALPO-Jupiter email list, other amateurs soon posted follow-up images. [more inside]

Armageddon's Deep Impact

An interactive map of the 174 major meteor impact craters. The largest crater we know of is the Vredefort Dome in South Africa, caused by a meteor some 10 km in diameter. Almost as large in the Sudbury Structure, located in Ontario, which contains some of the world's richest nickel and copper reserves, and has been only confirmed recently to be a crater. Third largest is the now-famous Chicxulub crater in the Yucatan, which probably killed the dinosaurs. Then take a look at an animation of asteroids near Earth [animated gif] and the list of minor planets that could hit us. Want to find out what happens when an meteor impacts in your area? Use the handy Earth Impacts Effects Program!

It's the end of the World as we know it...

How will civilization end? With a bang, a crunch(last link is PDF), a splash? Are we no longer more likely to kill ourselves than being killed by "Mother Nature"? (more inside)

The Wildlife Conservatory Society has just released a new map of the Human Footprint on Earth. With this map (pdf) you can see just how much wild space isn't left. For a closer look at each continent look here. So what do we do about it? Terraform the moon? Or maybe Mars? Or is our best bet for keeping Earth habitable simply to go electric?

And just to clarify, I'm talking about the impact of humanity on the earth's natural resources, not the supposed giants humans that walked with dinosaurs.

What is the future of online news.

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.

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?

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]
