Cosmos for creationists

Cosmos for creationists | Gavagai | Scoop.it

Over the following weeks since the show’s premiere, many creationists effectively covered their ears, saying 'La, la, la! I can’t hear you!' or have attacked the content of the show only to highlight the fact that they didn’t understand it and were closed off to learning. Now, it has hit a breaking point with Young Earth Creationists actually demanding equal air time to provide the 'science' of divine creation. What would their show even look like? Thanks to the folks at Funny Or Die, we have an answer.

Fossils give us a snapshot of life right after a huge meteorite impact | Gavagai | Scoop.it

About 14.6 million years ago, a meteorite over half a mile wide smashed into the Earth, creating a massive crater of melted rock. Although temperatures there were as high as 36,000 degrees Fahrenheit, researchers have found that life took hold there soon after.

What will happen when the Earth's magnetic field switches | Gavagai | Scoop.it
The Earth's magnetic field protects life on Earth, shielding it from damaging radiation and moderating our climate. So the idea that it could completely flip around, or collapse altogether, should cause us to worry, right? Well, yes and no.

Cassini may have witnessed the birth of a new Saturn moon

Cassini may have witnessed the birth of a new Saturn moon | Gavagai | Scoop.it
The potential moon (nicknamed Peggy) is tiny, probably only about a kilometer (0.6 miles) across — really a moonlet — and is invisible in the Cassini pictures. However, its presence is betrayed by an odd clumping of material at the very edge of Saturn’s A ring, the outermost of Saturn’s main rings.

Corvid behaviour: much to crow about | Gavagai | Scoop.it

By recreating the setting from Aesop's Fable 'The crow and the pitcher', researchers have shown that corvids are not just capable of grasping that solid objects displace water, but more crucially, they seem to understand the causal relationship between the properties of such objects and their effectiveness.

As humans, it’s tempting to think of ourselves as the pinnacle of evolutionary progress. But evolution can only work with what’s available, resulting in a body that’s a bundle of compromises.

Why are diamonds clear, but coal black?

Why are diamonds clear, but coal black? | Gavagai | Scoop.it

Diamonds and coal are different colors because coal isn’t pure carbon. The stuff is loaded with impurities: hydrogen, sulfur, mercury, and more. There’s a reason you don’t want to live next door to a coal-fired power plant and that reason is all the nasty stuff that gets released when the carbon in coal burns.

Scans can be vital in judging severity of brain damage | Gavagai | Scoop.it

Determining levels of consciousness in people who have severe brain injury is notoriously hard. That task may become a little easier with the finding that brain scans can help doctors identify whether patients in a vegetative or minimally conscious state are likely to recover to some degree.

For the first time, a mammalian organ has been persuaded to renew itself

For the first time, a mammalian organ has been persuaded to renew itself | Gavagai | Scoop.it

Clare Blackburn of Edinburgh University in Britain, and her colleagues have treated, in mice, an organ called the thymus, a part of the immune system that runs down in old age. Instead of adding stem cells they have stimulated their animals’ thymuses to make more of a protein known as FOXN1. This is a transcription factor (a molecular switch that activates genes), and for the thymus it turns out to be an elixir of life.
