Tanjore Brihadeeswara Temple - A Proof of Alien Existence?

The lush Tanjore city was the capital of Chola Emperors, before 1000 years. Among all the architectural wonders of the Cholas, the Tanjore Brihadeeswarar temple is their masterpiece. The temple was built by the great Raja Raja Chola, who was an avid devotee of Lord Shiva and arts and architecture of Dravidians.
Although many researches had been carried out to know the facts behind the temple construction, all of them went vain.

Great Unsolved Mysteries of Science

GIVEN the remarkable degree of understanding that science now provides about the physical world, it is easy to lose sight of the numerous, enormous unsolved mysteries that still haunt the dreams of scientists. Below is a list of some of the greatest of these unanswered questions which perhaps, with luck, will be answered (in part or in full) in the next hundred years. This list is by no means all inclusive, as there are important enigmas that remain in nearly every branch of science.

1. Dark Matter
We still have little understanding of dark matter, the strange and non-interacting material that seems to make up about 22% of the energy of our entire universe. We can infer its existence through its gravitational effects (which, for example, alter the properties of galaxies), but we have yet to detect it directly (though there are currently attempts underway to do so). If scientists are correct about dark matter’s existence, then it seems our own milky way galaxy has much more dark matter than other types of matter. There are a variety of theories now competing to describe what dark matter is composed of, but whatever it is it interacts so little with its environment that it can easily pass through our planet and our bodies without us being able to tell the difference.
2. Dark Energy
We still have very little idea about the nature of dark energy (which, despite its name, is unrelated to dark matter), a form of energy thought to permeate all of space. Dark energy appears to be required by theory in order to account for the idea that our universe has an accelerating rate of expansion (contradicting the old belief that gravity should be causing our universe’s growth to slow).

These weird helmet allows you to see through eyes of animals




In life, we only truly get to experience one perspective: our own. but we often wonder how the world looks through the eyes of, say, a deer. Or a dragon fly. Or a frog. Or an owl. I know I do!

Fortunately for us, the folks at the creative studio Marshmallow Laser Feast have discovered a new way for people to experience a walk through the woods – through the eyes of an animal.


The virtual forest rendering they’ve created allows you to experience the woods as some animals would.
Check out the video below for a real experience of life through the eyes of an animal.

This architect designed a self-sustaining underwater eco-village


Belgian architect Vincent Callebaut has made designs for an underwater ecovillage that is self-sustaining and could house up to 20,000 people.
The Aequorea project envisions spiraling “oceanscrapers” that are constructed entirely of recycled plastics of the Great Pacific Garbage Patch.
The Aequorea would house up to 20,000 people, have science labs, offices, hotels, sports fields and farms that would feed everyone in the eco-village. The plans call for 250 floors that reach a depth of 3,280 ft (1000 meters).

From science fiction to reality – a sonic tractor beam

UK researchers have invented a sonic tractor beam that can move small objects up to 40cm.
Tractor beams are mysterious rays that can grab and lift objects. The concept was created by science-fiction writers, but has since come to fascinate scientists and engineers. A team of researchers at the Universities of Sussex and Bristol, in collaboration with tech firm Ultrahaptics, have demonstrated a working tractor beam that uses high-amplitude soundwaves to generate an "acoustic hologram" able to pick up and move small objects.

sonic tractor beam 2015 technology
This technique, published yesterday in Nature Communications, could be developed for a wide range of applications. For example, a sonic production line could transport delicate objects and assemble them, without any physical contact. Or a miniature version could grip and transport drug capsules or microsurgical instruments through living tissue.
Sriram Subramanian, Professor of Informatics at the University of Sussex and co-founder of Ultrahaptics, explained: "In our device we manipulate objects in mid-air and seemingly defy gravity. We can individually control dozens of loudspeakers to tell us an optimal solution to generate an acoustic hologram that can manipulate multiple objects in real-time without contact."

Self-assembling material could lead to artificial veins

Researchers at Queen Mary University London (QMUL) have demonstrated a self-assembling organic material that grows and changes shape and which could lead to artificial veins.

Researchers at Queen Mary University of London have developed a way of assembling organic molecules into complex, tubular, tissue-like structures, without the use of moulds or techniques like 3D printing.
The study, published this week in the journal Nature Chemistry, describes how peptides and proteins can be used to create materials that exhibit dynamic behaviours found in biological tissues – like growth, morphogenesis, and healing.

self assembling organic material artificial arteries
The method uses solutions of peptide and protein molecules that, upon touching each other, self-assemble to form a dynamic tissue at the point at which they meet. As the material assembles itself, it can be easily guided to grow into complex shapes.

Self-healing sensor brings 'electronic skin' closer to reality

Scientists have developed a self-healing, flexible sensor that mimics the self-healing properties of human skin. Cuts or scratches to the sensors "heal" themselves in less than one day.

electronic skin future technology

Flexible sensors have been developed for use in consumer electronics, robotics, health care, and space flight. Future possible applications could include the creation of ‘electronic skin’ and prosthetic limbs that allow wearers to ‘feel’ changes in their environments.
One problem with current flexible sensors, however, is that they can be easily scratched and otherwise damaged, potentially destroying their functionality. Researchers in the Department of Chemical Engineering at the Technion – Israel Institute of Technology in Haifa (Israel), who were inspired by the healing properties in human skin, have developed materials that can be integrated into flexible devices to “heal” incidental scratches or damaging cuts that might compromise device functionality. The advancement, using a new kind of synthetic polymer (a polymer is a large molecule composed of many repeated smaller molecules) has self-healing properties that mimic human skin, which means that e-skin “wounds” can quickly “heal” themselves in remarkably short time – less than a day.

Futurist Predictions in the World of Technology

Avatar:















While avatars (like this one from the game Second Life) and surrogates were once just the stuff of games, virtual reality and computer interfacing, now they're taking on more active roles as replacements for living, breathing humans.

Maybe you aren't comfortable with all of the futurist predictions and even the current rate of technological advance, and that's OK. You can be yourself and interact in the world in a fairly low-tech way while allowing a surrogate, avatar or robot to live your online and tech life for you. Even the U.S. Defense Advanced Research Projects Agency (DARPA) has budgeted millions of dollars to create avatars that will act as surrogates for real, live soldiers
While avatars and surrogates were once the stuff of games, virtual reality and computer interfacing, they are taking on more and more active roles as replacements for living breathing humans. Or, are they enhancements for humans?

Fully-realized robotic machines have become more and more widespread in medical technology and scientific development, both in the lab and in hospitals, enabling those with paralysis to move limbs, for instance. "Living" life with 'second life' surrogates is likely to become more and more common every day for those of us in less specialized fields, too.
Neurocontrol
Will there be a day when you say "I can't read your mind, you know!" and the reply will be "Oh, stop it -- of course you can!"? It could happen. Neuroscientists are finding ways to read people's minds with machines, and although this has been in the works for decades, real progress is being made by researchers at the University of California, Berkeley, and elsewhere. Translating electrical activity from the brain by means of decoding brainwaves is one way to help sufferers of dementia, for example, who have complications with neurotransmitters relaying thoughts into comprehensible speech or holding thoughts long enough to get them out verbally before they're forgotten.
  • On the other hand, it is more than a little frightening to know that science and machines could soon have access to our innermost thoughts. Implications for neurohacking into people's thoughts have also been studied in relation to neuromarketing, which targets people's brains by manipulating their wants and desires through marketing and advertising. Our thoughts and actions could actually be hijacked by a form of media that makes us think we're getting what we want, when really, we're going for something our brains may only think is supposed to be good

Nokia is developing a phone that would charge while you're walking around with it!



Nokia has already created indestructible phones, but now the phone company is trying to create a phone that will harvest radio waves in order to recharge the battery on the phone while it is on standby.
Basically, whenever you're just sitting around on the couch watching television, your phone could be charging while in your pocket! The eventual goal for a phone like this would be that the user of the phone would NEVER have to plug their phone into something to charge it!

You don't know it, but your television, microwave, car, the phones of your friends and family all release radio waves, and these radio waves are going to be used to charge your cellphones, and maybe, other electronic devices!
A wireless transfer of energy has already been tried in 1893, where Nikola Tesla tried to send electricity to an intercontinental transmission tower! It was a little too futuristic for Tesla, but maybe not for Nokia!

Tiny Robot Mosquito Drones being Researched by the US Government

Story:

Is this a mosquito? No. It’s an insect spy drone for urban areas, already in production, funded by the US Government. It can be remotely controlled and is equipped with a camera and a microphone. It can land on you, and it may have the potential to take a DNA sample or leave RFID tracking nanotechnology on your skin. It can fly through an open window, or it can attach to your clothing until you take it in your home.

Analysis:

The story comes with a picture claiming to show a Mosquito spy drone that can take photographs and DNA samples of people, and that it is funded by the U.S government for tracking people.
It is a fact that there are reports suggesting that research is going on to develop the MAV's, i.e. Micro Air Vehicles in the form of tiny flying objects like a mosquito. The purpose of these MAVs is to be useful in scientific and military applications. The micro flying robot can have cameras, microphones and other sensors that can take pictures, videos and other useful scientific and biological information from people and places where humans (or the military) cannot reach. This way the tiny flying robots can also be used as spies and weapons against enemies.

Earlier Citations

In 2007, at the International Conference on Intelligent Robots and Systems (IROS), the latest developments in unmanned aerial vehicles (UAVs) were showcased. Scientists talked about the design of micro UAVs of insect-size that actually flap their tiny little wings, and convey important communication information in a given mission. Not just from U.S, there were in total 20 UAV-related papers at the conference, from four continents and eight countries, including Portugal, Germany, France, Switzerland, Japan, Australia, Mexico, and Brazil.
In 2008, the U.S. military engineers were trying to design flying robots disguised as insects which can fly and spy on enemies to conduct dangerous missions without risking human lives. Refer to an animated picture in the image section below. Greg Parker, who helps lead this research at Wright-Patterson Air Force Base in Dayton talks about this saying:
"The way we envision it is, there would be a bunch of these sent out in a swarm. If we know there's a possibility of bad guys in a certain building, how do we find out? We think this would fill that void."
Parker and his team planned to start and develop such a bird-sized robot as soon as 2015, followed by the insect-sized models by 2030.

The Facts

The picture shown in the story is not a real robot mosquito drone, but simply one such proposed 'prototype' that may become reality in future, and perhaps they will also be able to take photographs and DNA samples of people. But as of now, these are only speculations, and not facts in practical. A quote from RT America confirms the same:
As early as in 2007 the US government was accused of secretly developing robotic insect spies when anti-war protesters in the US saw some flying objects similar to dragonflies or little helicopters hovering above them. No government agency has admitted to developing insect-size spy drones though some official and private organizations have admitted that they were trying.

Watch the video, it explains the same story.

Flying Cars to Come Soon...
















Flying Cars to Come Soon - Facts Analysis

Story: 

The Flying Car - A Fantasy Soon To Come True!!
The flying car which is popularly called the TF-X will be a hybrid of a car, helicopter and plane, which can be driven as well as flown like a personal jet plane.
First model set to go on sale in two years - and there is even a version that can take off vertically if you get stuck in a traffic jam.

Analysis:

Circulating messages talk about the fantasy of flying cars becoming a reality soon, also those which can take off vertically when you get stuck in a traffic jam. It is a fact with some misinformation.
The flying car, known as the Transition Flying Car was developed by a Massachusetts based company called Terrafugia (means Escape the Earth in Latin). It was founded in Woburn by pilot-engineers from Massachusetts Institute of Technology. The company mainly works around building practical flying cars, and its motto is to bring personal aviation into the mainstream.

The Transition Flying Car

As mentioned in the message, the Transition flying car is an hybrid car, helicopter and plane that can be driven as well as flown like a personal plane. The hybrid flying car is a two-seater aircraft with folding wings. The company is keen on this street-legal airplane that converts between flying and driving modes within a minute.
The prototypes of these Transition cars have in fact been flying for years, as the company is testing its durability and the certification by federal aviation and highway safety agencies. The company said that it is planning to start delivering the flying car to customers in 2015 or 2016. In the first video, you can watch a test flight of this Terrafugia Transition flying car conducted in 2009.

The TF-X™

Terrafugia is also working on a successor model of this flying car called as TF-X™, which can take off and land vertically, flying at more than 200 mph and for 500 miles - carrying four people. The company announced about these studies of vertical takeoff and landing (VTOL) plug-in hybrid-electric flying car in a press statement released on May 5th, 2013. Terrafugia plans to incorporate the state-of-the-art intelligent systems and control technology in the proposed TF-X™ so as to increase the level of safety and comfort of personal aviation.
However, this vertical take off car is in the earliest stages of design and feasibility studies. The second video shows the design vision of this VTOL car. The company said that they are planning to develop the TF-X™ to have the most control over the flight so that even a person without a license would be able to fly it.
These flying cars will be a good news for the frustrated commuters, also for the fact that it gives them a new dimension of personal freedom.

Talking Angela app' is Dangerous to Children with Electronic Devices


'Talking Angela app' is Dangerous to Children with Electronic Devices - Facts Analysis

Story:

Warning for to all parents with children that have any electronic devices, ex : ipod, tablets etc.... there is a site called Talking Angela, this site asks kids questions like : there names, where they go to school and also take pictures of their faces by pushing a heart on the bottom left corner without any notices.
Please check your children's ipods and all to make sure they do not have this app !!! Please pass this message on to your friends and family that have kids !!!!

Analysis:

The message comes as a warning to all parents with children having electronic devices like ipods
and tablets, claiming that there is a site called Talking Angela that will hack the children's personal information including their pictures - without any notice. The message is not a fact.

About Talking Angela

Unlike mentioned in the message, Talking Angela is not a website as such, it is an interactive application for iOS, Android and Facebook. The app is a product from Out Fit 7 Ltd., the same company that developed the famous Talking Tom Cat app. Talking Angela is a two-way interactive app meant for entertainment, where Angela, the chat bot talks to the user about various topics and answers in text and voice. In Child Mode, the purpose of the Talking Angela app is to wait until the child says something and then mimic what they say back to them in a cat-like fashion.

Facts about Child Privacy

As mentioned in the message, the Talking Angela app does have a Heart button, but it does not take a picture without notice. When the heart button is pushed, the app takes your picture, and then pops up a screen with 'option' to share your picture with Angela on social networks like Facebook and Twitter. The app does not gather any personal information initially, but in payments page, just like other apps, does collect your personal information. However, the Legal Notice mentioned in the description of the app says that the personal information is only stored as anonymized data and not shared with anyone:
LEGAL NOTICE: We are collecting anonymized data log files containing details on the usage of the app. More details: http://outfit7.com/privacy/
And as mentioned in the privacy disclaimer of Out Fit 7, the company is also keen to protect children's privacy while using their products:
Our products and services are not directed to, and we do not knowingly collect personal information from, children under 13. If we learn that we have collected personal information of a child under 13, we will take all reasonable steps to delete the information as soon as possible.
If you become aware that your child has provided us with personal information without your consent, please contact us at http://outfit7.com/contact/
Therefore, the warning about Talking Angela as a threat to children's privacy appears to be nothing more than a scare. It need not be shared. However, it is always a good idea to keep a close eye on what your children are doing online, especially when they are using devices connected to internet

Smartphone Pictures Pose Privacy Risks


Smartphone Pictures Pose Privacy Risks - Facts

Warning if you take photos with your cell phone of your kids, grand kids, elderly family members --
WATCH THIS!
This is truly alarming - please take the time to watch this video, AND TAKE THE RECOMMENDED PRECAUTIONS. At the end they'll tell you how to set your phone so you don't run this risk!
PLEASE PASS THIS INFO TO ANYONE YOU KNOW WHO TAKES PICTURES WITH THEIR CELL OR SMART PHONE AND POSTS THEM ONLINE. Be sure to share with all your family and friends. This is important info, about what your posting pictures/info on your cell phones can do TO YOU!!! Too much technology out there these days so beware...........

I had no idea this could happen from taking pictures on the blackberry or cell phone. It's scary.

Analysis:


http://www.youtube.com/watch?v=N2vARzvWxwY

The Solution:

To avoid this risk, one can disable the Geotagging feature on their smartphone and digital cameras. From reference section below, you can learn how to do it in various smartphone devices. Instead, you can use Exif metadata editor to change/remove the location information associated with your pictures. Also, you can save your pictures in a format that does not support Exif metadata. But unlike what is warned, some social media sites like Facebook and Twitter in fact automatically delete the location data from the uploaded pictures. Google+ and Instagram do not delete this location information automatically, but provide an option of hiding it.

Brain implant could turn you into one of the X-Men
















Imagine this: RAW agents with enhanced senses of smell, emergency responders that can hear sounds clearly from beneath rubble and dirt, and cab drivers always knowing the direction of true north. This might sound like an issue of popular comic book series The X-Men, but scientists at Duke University are experimenting with a brain implant device that could make these things possible in the real world — and without the need to be born a mutant.
As it stands, our five senses are very limited, although our brain capacity should be able to allow us to do more with them. The Duke scientists wanted to explore the possibility of using a brain implant in possibly turning up and enhancing those senses. The implants were used on mice, which allowed the mice to be taught to see infrared light, which is generally invisible to the naked eye.
The experiment began with teaching the mice to recognize an LED light: when it lit up, the mice learned to poke their noses into an appropriately-related hole. Infrared cameras were then attached to their heads and wired into their brains where sensory processing occurs naturally. Then, the animals were exposed to infrared light. The camera would stimulate the brain, becoming stronger as the mice got closer to the infrared light or looked in its direction. After that, the mice were put back into their original surroundings and the LED light was replaced with an infrared light. Although it took nearly a month of training, the mice learned to respond to the infrared light by poking their noses in the correct holes.
The mice also responded to additional stimulation, leading the scientists to believe that the brain can handle a variety of sensory input via the implant at any given time. This could lead to better prosthetics for artificial limbs in the future, allowing those wearing them to have better control over those parts of their bodies. There is also the potential for ordinary humans to be given super-human sensory powers, making something like The X-Men more reality than fiction.

Light Stopped Inside Crystal For A Whole Minute By Scientists



Introduction:
In the ever-evolving realm of science and technology, a group of researchers from the University of Darmstadt has achieved something truly extraordinary. They've managed to stop light for an entire minute inside a crystal. To put this feat into perspective, it's like hitting the pause button on a phenomenon that is universally recognized as the fastest thing in the universe. The implications of this achievement are far-reaching and open up exciting possibilities in the world of quantum communication and information storage.

Light: The Usain Bolt of the Universe
To understand the significance of this accomplishment, let's first appreciate the speed of light. In a vacuum, it travels at a mind-boggling 299,792,458 meters per second (over 980 million feet per second). Whether light behaves as a wave or a particle remains a subject of debate among scientists, but its speed is undeniable. So, the ability to slow it down for a whole minute is nothing short of amazing.

A Journey of Milestones
This journey to stop light didn't happen overnight. In 1999, the first attempt to alter the speed of light resulted in it being slowed to a mere 17 meters per second. Subsequent efforts in 2001 allowed scientists to pause light for less than a second. Even earlier this year, a breakthrough had light being stopped for a mere 16 seconds.

The Crystal Key
So, how did this research team manage to hit the one-minute mark? They used an ingenious approach involving an opaque crystal and laser beams. By disrupting the quantum states of the crystal's atoms, they created two states within the crystal. One of these states became transparent to a specific frequency of light.

Then, a laser beam of that frequency was directed into the crystal. Almost simultaneously, another laser beam was fired, which rendered the crystal opaque again. For those precious seconds, light was effectively trapped within the crystal. Magnetic fields were also employed to extend the crystal's storage time.

Mind-Boggling Comparisons
Just how incredible is the feat of stopping light for a minute? To put it in perspective, during that time, light could have traveled between Earth and the moon a staggering 20 times. It's an astonishing achievement that hints at the limitless potential of human ingenuity.

Quantum Communication's New Frontier
This groundbreaking achievement has profound implications, particularly in the realm of information storage. It's a game-changer for quantum communication. Quantum communication relies on the principles of quantum entanglement, enabling secure communication over vast distances. Quantum repeaters, which require the storage of quantum information for extended periods, are now within reach.

The Practical Implications
In a remarkable experiment, the research team encoded a laser with simple information. Even after the light was stopped for a full minute, the information could be retrieved. This discovery hints at the incredible applications this technology may soon have. Think of it as a quantum version of data storage, offering unprecedented security and reliability.

The Future Beckons
While this achievement is certainly thrilling, it's important to note that more research is required to harness its full potential. Scientists are already exploring other materials and methods that could further extend the storage time of light. The possibilities seem boundless, from quantum computing to revolutionizing secure long-distance communication.

In conclusion, the ability to stop light in its tracks for a whole minute is a testament to human innovation and scientific progress. It's a quantum leap towards a future where secure, long-distance communication and data storage are not just dreams but practical realities. The speed of light, once an absolute constant, is no longer an insurmountable barrier, thanks to the brilliance of our scientists.

3D printing with paper


THERE are more than a dozen sorts of three-dimensional (3D) printer. They all build up objects, layer by layer, but what the layers are made of varies from one to another. Some extrude filaments of molten plastic. Some spray special “inks”, such as liquid polymers that solidify when exposed to ultraviolet light. Some use powdered plastic or powdered metal that is then fixed in place with a laser or an electron beam. Now there is yet another way. Staples, an office-supplies company, has introduced it at its store in Almere in the Netherlands. And the layers their machine prints are made of a substance that Staples has in abundance: A4 sheets of paper.

The process was invented by Conor MacCormack, an Irish aerospace engineer, and his brother Fintan, an electrical engineer. They worked with 3D printers but found the materials expensive. (Many manufacturers put a high markup on their bespoke printing materials, just as the producers of 2D printers do on their ink.) The MacCormacks therefore set out to make a full-colour 3D printer with exceptionally low operating costs. They call the result “Selective Deposition Lamination” (SDL) and they reckon the cost of the paper needed for it works out at about 5% of the cost of the materials for other 3D systems.
Like those other systems, SDL begins by taking a series of digital slices through the object to be replicated. These are then sent to the printer, which reproduces each layer in turn. In the case of SDL, the process starts by the machine applying drops of adhesive to a sheet of paper. More adhesive is applied to the area which will form the first layer of the object; less (but still some) is applied elsewhere. The lightly glued area acts as a support while the structure is built up.
Next, the machine slides a second sheet of paper on top of the first and presses them together to bond them. This done, it uses a tungsten-carbide blade to slice around the outline of the object (ie, between the heavily and lightly glued areas). The process continues, layer by layer, until the object is complete. It is then removed from the machine, the supporting material is peeled away, and the finished item, which has a consistency similar to wood (not surprising, since paper is made of wood pulp), is revealed.
Adding colour involves a bit of old-fashioned two-dimensional printing. Each sheet, before it is put in the stack, is printed top and bottom with appropriate ink in a pattern that follows the edge of the item at the level this sheet of paper will occupy. The ink soaks through the paper so that when it is cut no white is visible.
So far the new printers, which are made by the MacCormacks’ company, Mcor Technologies, have been used mainly to produce things like architects’ models, three-dimensional maps, prototypes of parts, moulds and various arts-and-crafts items such as figurines. A doctor is also using a Mcor machine to make surgical guides for facial reconstruction. Staples hopes people will use their imaginations and print all sorts of other things as they expand the service to more stores. And one day, as more office documents migrate to cyberspace, 3D printing with paper may even overtake the 2D sort
