WWI-Era Dazzle Camouflage Could Protect Modern Military Vehicles



During World War I, the navies of the world experimented with dazzle camouflage. The odd angular shapes and lines, such as those seen on the British minelayer pictured above, broke up the visual patterns of the vessels, making them harder to see at a distance. Now researchers at the University of Bristol (UK) think that it could still be useful for land vehicles on modern battlefields:

High-contrast dazzle camouflage could throw off an attacker’s perception of a target’s speed by a wide enough margin to cause a miss, the researchers said.

“In a typical situation involving an (rocket-propelled grenade) attack on a Land Rover, the reduction in perceived speed would be sufficient to make the grenade miss where it was aimed by about a meter (3.3 feet), which could be the difference between survival or otherwise for the occupants of the vehicle,” said Nick Scott-Samuel of the University of Bristol.


They arrived at this conclusion by examining the ability of people to perceive the speeds of objects covered variously by dazzle and conventional camouflage patterns. Participants experienced a 7% greater difficulty gauging the speed of the dazzle-covered objects -- which could be enough to save the lives of a significant number of soldiers.

The Top Ten Ghost Ships

The term ghost ship can refer to a mysterious apparition of a ship when a ship is not really there, or it can refer to an abandoned ship found with no crew or passengers, usually under mysterious circumstances. Both kinds are listed in these ten stories spooky enough to share with anyone to whom you want to give nightmares. Pictured is the Baychimo, used in Arctic waters until it became trapped in ice in 1931. The crew was airlifted and the ship abandoned. However, the boat survived to mysteriously float on its own for decades. It was last seen in 1969. Link -via Unique Daily

They're Alive: Real Scientific Reasons to Believe in Vampires, Werewolves, and Zombies


Dracula vs. Cujo

One dark and stormy evening, Spanish neurologist Juan Gomez-Alonso was watching a vampire movie when he realized something strange; he noticed that vampires behave an awful lot like people with rabies. The virus attacks the central nervous system, altering the moods and behaviors of those infected. Sufferers become agitated and demented, and, much like vampires, their moods can turn violent.

Rabies has several more vampire-like symptoms. It can cause insomnia, which explains the nocturnal portion of the legend. People with rabies also suffer from muscular spasms, which can lead them to spit up blood. What’s stunning is the fact that these spasms are triggered by bright lights, water, mirrors, and strong smells, such as the scent of garlic. (Sound Familiar?)

After watching the Dracula movies a few more times, Dr. Gomez Alonso felt compelled to continue studying vampire folklore and the medical history of rabies. Eventually, he discovered an even more profound connection between the two phenomena: Vampires stories became prominent in Europe at exactly the same time certain areas were experiencing rabies outbreaks. This was particularly true in Hungary between 1721 and 1728, when an epidemic plagued dogs, wolves, and humans and left the country in ruins. Gomez-Alonso theorized that rabies actually inspired the vampire legend, and his research was published by the distinguished medical journal Neurology in 1998.

The Madness Of King George

Dr. Gomez-Alonso wasn’t the first scientist who tried to pin vampirism to a real illness. In 1985, Canadian biochemist David Dolphin proposed a link between vampires and porphyria- a rare, chronic blood disorder characterized by the irregular production of heme, an iron-rich pigment found in blood. The disorder can cause seizures, trances, and hallucinations that last for days or weeks. As a result, people with porphyria often go insane. (Britain’s Kin George III, the one who inspired our founding fathers to start their own country, is thought to have suffered from it.) Porphyria sufferers also experience extreme sensitivity to light, suffering blisters and burns when their skin is exposed to the sun. Another symptom of porphyria is an intolerance to sulfur in foods. Which food contains a lot of sulfur? That’s right, garlic.
