Science Debunks Halloween, Part 3: No Ghosts

Using Isaac Newton's Laws of Motion, scientists have demonstrated that ghosts would not be able to walk and pass through walls

In movies such as “Ghostbusters”, ghosts often walk like humans, pass through walls and pick up objects. But that portrayal cannot be accurate, Efthimiou says. For ghosts to have the ability to walk like humans, they would need to put a force upon the floor, which would exert an equal and opposite force in return.

But ghosts' ability to pass through walls and have humans walk right through them demonstrates that they cannot apply any force. LINK

Science Debunks Halloween, Part 2: No Zombies

The laws of science can debunk popular myths zombies according to a paper published by Efthimiou and Sohang Gandhi.

"These popular myths make for a lot of Halloween fun and great movies with special effects, but they just don't hold up to the strict tests of science," Efthimiou said.

Efthimiou provides a practical explanation for "voodoo zombiefication," which suggests that zombies "come about by a voodoo hex being placed by a sorcerer on one of his enemies." He reviewed the case of a Haitian adolescent who was pronounced dead by a local doctor after a week of dramatic convulsions.

After the boy was buried, he returned in an incoherent state, and Haitians pronounced that a sorcerer had raised him from the dead in the state of a zombie.

Science, however, has a less-supernatural explanation. A highly-toxic substance called tetrodotoxin is found in a breed of puffer fish native to Haitian waters. Contact with this substance generally results in a rapid death. However, in some cases, the right dose of the toxin will result in a state that mimics death and slows vital signs to a level that is unable to be measured. Eventually, the victim snaps out of the death-like coma and returns to his or her regular condition.



Scientific analysis has shown that oxygen deprivation is consistent with the boy's brain damage and his incoherent state.

"It would seem that zombiefication is nothing more than a skillful act of poisoning," Efthimiou said. LINK

Science Debunks Halloween, Part 1: No Vampires

The laws of physics and math debunk popular myths about ghosts and vampires, according to a newly published paper.



Basic math disproves the legend of humans turning into vampires after they are bitten, Efthimiou explains, because the entire human population in 1600 would have been wiped out in less than three years.

Movies such as "Dracula" suggest that vampires feed on human blood and that once a human has been bitten, he or she turns into a vampire and begins feeding on other humans. To disprove the existence of vampires, Efthimiou relied on a basic math principle known as geometric progression.

Efthimiou supposed that the first vampire arrived Jan. 1, 1600, when the human population was 536,870,911. Assuming that the vampire fed once a month and the victim turned into a vampire, there would be two vampires and 536,870,910 humans on Feb. 1. There would be four vampires on March 1 and eight on April 1. If this trend continued, all of the original humans would become vampires within two and a half years and the vampires' food source would disappear.



"In the long run, humans cannot survive under these conditions, even if our population were doubling each month," Efthimiou said. "And doubling is clearly way beyond the human capacity of reproduction." LINK

Gamma Rays From M87

Astrophysicists report the discovery of fast variability in very-high-energy (VHE) gamma rays from the giant elliptical galaxy M 87. The detection of these gamma-ray photons - with energies more than a million million times the energy of visible light - from one of the most famous extragalactic objects on the sky is remarkable, though long-expected given the many potential sites of particle acceleration (and thus gamma-ray production) within M 87.



Much more surprising was the discovery of drastic gamma-ray flux variations on time-scales of days. These results, for the first time, exclude all possible options for sites of gamma-ray production, except for the most exciting and extraordinary one: the immediate vicinity of the super-massive black hole which is located in the centre of M 87

Morbid Anatomy of Some of the Most Important Parts of the Human Body

More Atomic Surgery in Action!

Matthew Baille, a Scottish pathologist, was born this day in 1761. His book, Morbid Anatomy of Some of the Most Important Parts of the Human Body (1793), was the first publication in English on pathology as a separate subject and the first systematic study of pathology ever made. It established morbid anatomy as an independent science. The first American edition was published in Albany in 1795.

John Peel's Record Collection

LINK

John Peel left his coveted collection of more than 25,000 records to his wife in his will, it emerged last night. Sheila Ravenscroft will also receive the legendary Radio 1 DJ's estate, valued at more than £1.5m.

Ravenscroft was granted the 25,000 vinyl albums and thousands of CDs after Peel, who died in October 2004, failed to specifically assign them in his will. In typically laid-back fashion, he said: "I ask her (but without imposing any binding obligation) to give effect to any wishes of mine which may come to her attention as to their disposal."

Peel's four children were left more than £250,000 in trust to be split between them. Peel enjoyed national acclaim in a career that spanned over 40 years and included Radio 4.
