Landmines are explosive wartime weapons. People bury them or leave them on the ground for their enemies to step on or drive over. Yet once peacetime arrives, some of these buried bombs may remain behind. They’re often in empty fields, where they can maim or kill innocent civilians. But a new technology can make it easy to find landmines — even from a safe distance. And this might let bomb crews disarm these weapons before someone gets hurt.
The International Campaign to Ban Landmines (ICBL) is a group based in Geneva, Switzerland. It aims to end the use of these explosives. These mines had become such a big problem that an international Mine Ban Treaty was enacted in 1997. ICBL played a major role in getting countries to agree to the ban. For its success, ICBL and its coordinator — Jody Williams — shared the 1997 Nobel Peace Prize. Yet even today, millions of these bombs may still be buried out of sight across the world, according to the United Nations. In 2015 alone, the group notes, landmines and similar bombs killed or injured more than 5,000 civilians. Almost four in every 10 of the victims were children. Trained workers typically go into a field with metal detectors to find and remove mines. But sometimes they don’t find the mines until they’re right on top of them, which can be very dangerous. That’s why the new technology is so promising. Using it, scouts now can identify landmines from a distance. Then they can send in experts to cautiously defuse or detonate the bombs.

By 1880, the U.S. population had grown so large that it took more than seven years to tabulate the U.S. Census results. The government sought a faster way to get the job done, giving rise to punch-card based computers that took up entire rooms.
Today, we carry more computing power on our smartphones than was available in these early models. The following brief history of computing is a timeline of how computers evolved from their humble beginnings to the machines of today that surf the Internet, play games and stream multimedia in addition to crunching numbers. 1801: In France, Joseph Marie Jacquard invents a loom that uses punched wooden cards to automatically weave fabric designs. Early computers would use similar punch cards. 1822: English mathematician Charles Babbage conceives of a steam-driven calculating machine that would be able to compute tables of numbers. The project, funded by the English government, is a failure. More than a century later, however, the world’s first computer was actually built. 1890: Herman Hollerith designs a punch card system to calculate the 1880 census, accomplishing the task in just three years and saving the government $5 million. He establishes a company that would ultimately become IBM. 1936: Alan Turing presents the notion of a universal machine, later called the Turing machine, capable of computing anything that is computable. The central concept of the modern computer was based on his ideas. Read Article: http://www.livescience.com/20718-computer-history.html What is the cloud? Where is the cloud? Are we in the cloud now? These are all questions you've probably heard or even asked yourself. The term "cloud computing" is everywhere.
In the simplest terms, cloud computing means storing and accessing data and programs over the Internet instead of your computer's hard drive. The cloud is just a metaphor for the Internet. It goes back to the days of flowcharts and presentations that would represent the gigantic server-farm infrastructure of the Internet as nothing but a puffy, white cumulus cloud, accepting connections and doling out information as it floats. Read Article: http://www.pcmag.com/article2/0,2817,2372163,00.asp The future is now, or at least it is coming soon. Today's technological developments are looking very much like what once was the domain of science fiction. Maybe we don't have domed cities and flying cars, but we do have buildings that reach to the heavens, and drones that soon could deliver our packages. Who needs a flying car when the self-driving car -- though still on the ground -- is just down the road?
The media often notes the comparisons of technological advances to science fiction, and the go-to examples cited are often Star Trek, The Jetsons and various 1980s and 90s cyberpunk novels and similar dark fiction. In many cases, this is because many tech advances actually are fairly easy comparisons to what those works of fictions presented. On the other hand, they tend to be really lazy comparisons. Every advance in holographic technology should not immediately evoke Star Trek's holodeck, and every servant-styled robot should not immediately be compared to Rosie, the maid-robot in The Jetsons.

Liquid crystals fall somewhere in between a liquid and a solid: they are made up of molecules that flow around freely as if they were a liquid but are all oriented in the same direction, as in a solid. Liquid crystals can be found in nature, such as in biological cell membranes. Alternatively, they can be made artificially -- such as those found in the liquid crystal displays commonly used in watches, smartphones, televisions, and other items that have display screens.

It had a range of functions, including medical ones. For example, it easily diagnosed injuries and disease in the Starfleet crew. Now, aspects of this science fiction invention are becoming reality. A device called DxtER has just won a multi-million-dollar competition. One day soon, the winners hope, such a tricorder-like device might become part of regular home health care — much like a medical thermometer is today.
In 2012, the XPRIZE Foundation and Qualcomm, a technology company, issued a challenge to inventors: Build the best real-world tricorder and you might just take home millions of dollars. The idea was to create some device that could help people diagnose ails from home. This would be particularly useful for those living in remote parts of the world with no easy access to doctors.

Recently, the team used its considerable expertise to create a prosthesis allowing a would-be cello player with only one arm to play his instrument of choice. Thanks to the tool they built, the Pittsburgh-based budding musician was able to play at his grade school recital.
