Roller Coaster of Death

That’s the purpose of the “Euthanasia Coaster,” a giant big-dipper design aimed at taking its passengers through a series of extreme drops and loops that would create euphoria and then kill them by starving the brain of oxygen. This macabre invention is the brainchild of Lithuanian engineer Julijonas Urbonas, who designed it in 2010 as a Ph.D. candidate in design interactions at the Royal College of Art in London. Urbonas, who developed a romance for amusement parks during the years he worked at one, saw this horror-movie scenario as an alternative death ritual propelling people to the afterlife, as he puts it, “humanely with elegance and euphoria.” No one’s actually built it yet, except as a scale model.

But this touch feedback technology has uses far beyond enhancing your game experience; it’s used in rehabilitation of stroke patients and even surgical training. 10 Scientific Ideas That Scientists Wish You Would Stop Misusing. I highly agree with #6, because I see even proper scientists getting really confused about what they consider to be a 'gene', and fuss over the definition of 'junk DNA', when there are better words to explain the various elements found in DNA.

10 Scientific Ideas That Scientists Wish You Would Stop Misusing

You have protein coding DNA, you have RNA coding DNA, and you have a variety of promoters, inhibitors, and enhancers that control the production of all of those, plus other binding spots for proteins of various sorts.

Plants Know They Are Being Eaten

And they don't like it. That plants possess an intelligence is not new knowledge, but according to Modern Farmer, a new study from the University of Missouri shows plants can sense when they are being eaten and send out defense mechanisms to try to stop it from happening. The study was carried out on thale cress, or Arabidopsis as it's known scientifically, which is closely related to broccoli, kale, mustard greens, and other siblings of the brassica family and is popular for science experiments.

It is commonly used in experiments because it was the first plant to have its genome sequenced, and scientists are intimately familiar with how it works. The researchers controlled the experiment by coming up with other vibrations that simulated other natural vibrations like wind noise that the plant might encounter. The results? How 3D Printing Humans Might Be Possible Some Day. 3D printing is all the rage right now; people are printing machine parts, statues of cosplayers, model homes, and even prosthetic hands that look like Iron Man’s.

Voyager 1 Hits Rumble Strips At the Edge of the Solar System

After 35 years of travel, NASA’s oldest interstellar spacecraft is now some 20 billion kilometres from the Sun. It’s easy to imagine that conditions in this isolated region of space would be quiet and calm but on 25 August, the spacecraft’s instruments suddenly went haywire, recording changes unlike anything it has seen throughout its long journey. Today, Bill Webber at New Mexico State University in Las Cruces and a few pals detail the dramatic changes Voyager has experienced and suggest various explanations for the phenomenon. Voyager 1 is currently investigating the outer reaches of the Sun’s influence, the region where the solar magnetic field ploughs into the galactic field as the Sun moves through the Milky Way.

This creates a magnetic bow wave that traps charged particles in various ways. 12 Events That Will Change Everything, Made Interactive.

I CONTACT is essentially a mouse fitted to your eyeball. The lens is inserted like any other normal contact lens except it’s laced with sensors to track eye movement, relaying that position to a receiver connected to your computer. Theoretically that should give you full control over a mouse cursor. I’d imagine holding a blink correlates to mouse clicks. The idea was originally created for people with disabilities but anyone could use it. Spontaneous Human Combustion. Spontaneous Human Combustion Spontaneous human combustion is the alleged burning of a person's body without a readily apparent, identifiable external source of ignition. The combustion may result in simple burns and blisters to the skin, smoking, or a complete incineration of the body. Evolution Of Man. Evolution Of Man - What is it? The modern theory concerning the evolution of man proposes that humans and apes derive from an apelike ancestor that lived on earth a few million years ago.

The theory states that man, through a combination of environmental and genetic factors, emerged as a species to produce the variety of ethnicities seen today, while modern apes evolved on a separate evolutionary pathway. Perhaps the most famous proponent of evolutionary theory is Charles Darwin (1809-82) who authored The Origin of Species (1859) to describe his theory of evolution.

C.C.T.-TED VIDEOS. How High Can We Build? Slab of Barrier Reef sea floor collapsing, could cause tsunami, say scientists. By Agence France-PresseThursday, December 20, 2012 21:45 EDT A huge slab of sea floor near the Great Barrier Reef is in the early stages of collapse and could generate a tsunami when it finally breaks off, researchers warned Friday. Marine geologists from Australia’s James Cook University have been using advanced 3D mapping techniques on the deepest parts of the reef — below diving depth — since 2007 and have discovered dozens of sub-marine canyons. On a recent trip, they came across the one cubic kilometre slab of sea floor, the remains of an ancient underwater landslide, which is perched on the continental shelf. Transparency - Walk This Way.

Continuum of Change: The Hairless Human. Darwin doubters have sometimes questioned evolutionary theory by asserting that no “missing link” exists between humans and other primates. But the fossil record shows that there was no instant leap to humanity: rather our species’ physical hallmarks appeared gradually over the past several million years. “Humans did not suddenly come into existence, but we share features with many other [species],” John G.
