Who doesn’t enjoy a morbid love of vampires? And who doesn’t love the history of vampires even more?

What Vampire Graves Tell Us About Ancient Superstitions

Hundreds of years ago, ignorance about decomposition and disease sparked fears that the dead returned to drink the blood of the living.

“In 1846, a man named Horace Ray died of tuberculosis in Griswold, Connecticut. Within the next six years, two of his grown sons died of the same disease. When yet another son fell ill two years later, Ray’s family and friends could think of only one explanation: The dead sons were somehow feeding on and sickening the living one—from the afterlife. In an effort to keep the remaining son from getting even worse, they exhumed the dead sons’ bodies and burned them.

This wasn’t an isolated incident. In 1874, a Rhode Island man named William Rose dug up his own daughter’s body and burned her heart, and in 1875 a victim of “consumption,” as TB was called then, had her lungs burned posthumously for good measure.

This practice of digging up, burning, or otherwise attempting to restrain the deceased was a widespread practice in many Western countries until the early 20th century, and it was intended to prevent what people at the time thought of as vampires: Dead victims of disease that literally sucked the life out of the living from beyond the grave.

We now imagine vampires as blood-drinking, cloaked Counts—or possibly sparkly, sexy teenagers—but throughout history everyone from the Ancient Greeks, to the Eastern Europeans, to 19th-century Americans saw them as disease victims (and sometimes simply dead miscreants) who could prey on the living from the Great Beyond…”

Chickens with dino snouts. What will they think of next?

Chicken Grows Face of Dinosaur

by Melissa Hogenboom (Earth Blog – BBC)

A chicken embryo with a dinosaur-like snout instead of a beak has been developed by scientists

“Sixty-five million years ago, an asteroid is believed to have crashed into Earth. The impact wiped out huge numbers of species, including almost all of the dinosaurs.

One group of dinosaurs managed to survive the disaster. Today, we know them as birds.

The idea that birds evolved from dinosaurs has been around since the 19th century, when scientists discovered the fossil of an early bird called Archaeopteryx. It had wings and feathers, but it also looked a lot like a dinosaur. More recent fossils look similar.

But these early birds didn’t look the same as modern ones. In particular, they didn’t have beaks: they had snouts, like those of their dinosaur ancestors.

To understand how one changed into another, a team has been tampering with the molecular processes that make up a beak in chickens…”

Civilization is very, very ancient indeed. But did it start with humans, or someone much older?

Oldest stone tools raise questions about their creators
The 3.3-million-year-old implements predate the first members of the Homo genus.
by Ewen Callaway (Nature)

“The oldest stone tools on record may spell the end for the theory that complex toolmaking began with the genus Homo, to which humans belong. The 3.3-million-year-old artefacts, revealed at a conference in California last week, predate the first members of Homo, and suggest that more-ancient hominin ancestors had the intelligence and dexterity to craft sophisticated tools.

“This is a landmark discovery pertaining to one of the key evolutionary milestones,” says Zeresenay Alemseged, a palaeoanthropologist at the California Academy of Sciences in San Francisco, who attended the talk at the annual meeting of the Paleoanthropology Society in San Francisco, on 14 April.

More than 80 years ago, anthropologist Louis Leakey found stone tools in Olduvai Gorge in Tanzania. Decades later, he and his wife Mary and their team found bones from a species that the Leakeys named Homo habilis — ‘the handy man’. This led to the prevailing view that human stone-tool use began with Homo, a group that includes modern humans and their big-brained and tall forebears. The oldest of these Oldowan tools date to 2.6 million years ago — around the time of the earliest Homo fossils. Climate upheavals that transformed dense forest into open savannah might have catalysed ancient humans into developing the new technology so that they could hunt or scavenge grass-eating animals, the theory goes…”
