Corneal (EYE) tattooing is not only possible, but it has been known and done now for over 2,000 years — it became almost commonplace in the late 19th century and into the 20th century to correct defects such as corneal scarring and leucomas. These days, it is done less often because contact lenses are very effective at covering these defects, and prosthetic technology is also more accessible. However, not everyone can wear contact lenses, and not everyone wants their eyeball popped out even if it is blind; hence cosmetic tattooing of the eye.
The U.S. military’s premiere research agency is already trying to use math to predict human behavior and neuroscience to replicate a primate’s brain. The next step: Lean on the study of energy and heat to create an entirely new theory for how intelligence actually works.
Where you live has a good deal to do with how you will die. In the United States, the top two causes of death are responsible for more than 50 percent of the annual death toll. In the world at large, there's a lot more variety in how you meet your Maker. Here is our list of the 15 most common causes of death in the United States.
Global warming is the long-term, cumulative effect that greenhouse gases, primarily carbon dioxide and methane, have on Earth's temperature when they build up in the atmosphere and trap the sun's heat. It's also a hotly debated topic. Some wonder if it's really happening and, if it's real, is it the fault of human actions, natural causes or both? When we talk about global warming, we're not talking about how this summer's temperatures were hotter than last year's. Instead, we're talking about climate change, changes that happen to our environment, atmosphere and weather over time. Think decades, not seasons. The term global warming itself is a bit deceptive because it implies we should expect things to get hotter -- not necessarily stormier, drier and even, in some instances, colder. Climate change impacts the hydrology and biology of the planet -- everything, including winds, rains and temperature, is linked. Scientists have ob served that the Earth's climate has a long history of variability, from the cold climes of the Ice Age to temperatures as hot as an Easy-Bake oven. These changes are sometimes noted over a few decades and sometimes stretch over thousands of years. What can we expect from a planet undergoing climate changes? Scientists studying our climate have been able to observe and measure changes happening around us. For example, mountain glaciers are smaller now than they were 150 years ago, and in the last 100 years, the average global temperature has increased by roughly 1.4 degrees F (0.8 degrees C) [source: EPA]. Computer modeling allows scientists to predict what could happen if the climate pattern continues on its current course, projecting, for instance, that temperatures could rise an average of 2 to 11.5 degrees F (1.1 to 6.4 degrees C) by the end of the 21st century [source: EPA]. In this article, we'll look at 10 of the worst effects of climate change, including some immediate effects observed and some hypothesized through climate modeling.
The following is a reprint from Uncle John's Bathroom Reader Plunges Into the Universe. A while ago, we posted "10 Things That Science Fiction Got Wrong" but believe it or not, there are many things that sci-fi got right as well. From communication satellites to robotic pets, here are a few of the things that science fiction nailed before they happened. Science fiction is supposed to predict future events - and to be entirely honest, some of us are getting impatient waiting for our own rocket cars to the Moon, which we understood we'd have by now. Be that as it may, here are some things dreamed up by science fiction writers that are part of our real world.
Google is serious about scanning books. Throughout the objections raised over the years by authors and publishers and the more recent delays in its settlement with the Authors Guild, Google has been scanning millions of books all along trying to digitize as many as it possibly can. It is so serious about capturing and indexing the knowledge stored in books that it has a patent, which was issued on March 24, 2009, on how to scan books faster than was previously possible.
