Millions of people all over world use contact lenses to avoid wearing glasses or to escalate the appearance of their eyes. Usually, contact lenses offer better peripheral vision and do not affected by the rain, snow, or sweat. But, the matter is that, contact lenses can not tolerate fire because heat from fire melts the contact lenses as lenses are made of plastic. However, people also can go through cosmetic surgery instead of using contact lenses. Recently, a doctor, named Dr. Gregg Homer, who is the founder of the medical equipment company Stroma Medical, California, United States, has developed a new laser treatment to change the color of eyes to increase the appearance of the eyes.

According to the developer of the treatment, application of the laser light for 20 seconds can eliminate the pigments of the eyes, which helps to change the color of eyes form brown to blue. The blue color is already present in everyone’s eye, which is not visible for the pigments of the brown color. As the laser light eliminates the pigments permanently, the blue color would be permanent and irreversible.

During this treatment, firstly, the pigments in the iris are determined using computerized scanning system. Then a tolerable laser light is applied to a spot of the iris that agitates the pigments. Repeating the process for 20 seconds, the laser is applied to the whole areas where the pigments situated. At the end of the first week of the treatment, the eyes become darker. In the meantime, the digestion process starts, which changes the eye color to blue after two to three weeks.

However, some eye specialist have stated against the newly developed laser treatment. According to them, the elimination of the pigments could carry some eye problems like glare or double vision. They said that without the pigments, the eyes are not capable to control the light getting in. On the other hand, Homer strictly said that the laser treatment has no side effects. “This is only around one third to one half as thick as the pigment at the back of the iris and has no medical significance,” he said. He also admitted that he tested for several medical safeties before and after the treatment for three months. He said, “Thus far we have no evidence of any injury.”

The company believes that the laser treatment will be popular than the contact lenses and other cosmetic surgeries. Completing a survey Stroma Medical got that about 17 percent of 2,500 people are interested for the treatment and 35 percent of them would seriously consider it, according to the BBC reports. The company is now in search of an investment of $750,000 to complete the clinical observations. Homer estimated that the laser treatment would cost about $5,000.

Gaston Tissandier was the first airship that was run using electric motor. After that many aircraft have been developed like Charles Renard, Arthur Krebs, Antares 20E, e-Genius etc. However, recently, a team of three engineers, from the German company e-volo, has developed a new electric aircraft that is little bit different from the others.

Thomas Senkel, the lead engineer of the project, announced the successful flight of the newly developed aircraft and the helicopter was only 1 minute 30 second beyond the earth at its first flight.

The inventors of the aircraft used 16 electric blades, and so called electric multicopter. The blades have individual power supplies and motor controllers. The motors are organized in its four arms and each arm consists of four motors. The designed multicopter is very much simpler than the conventional helicopters as it can be controlled simply by joystick, like a computer game helicopter, with the pilot sitting above the blades. There is only one seat for the pilot and the overall weight of the multicopter is only 80 kilograms.

“The flight characteristics are good natured. Without any steering input it would just hover there on the spot,” said Thomas. The multicopter can be used for examining pipelines, as air-car, and where a big helicopter can not be used. The multicopter is currently capable to fly for around 20 minutes because it runs on lithium-ion batteries. However, the engineers are still working to develop hour-long flights in the near future.

The engineers said that the multicopter could fly if up to four motors fail. The controls could be integrated with GPS software so that the multicopter could avoid obstacle automatically. The company is planning to ship the multicopter commercially that would have one or multi-seat for the pilots.

The Facebook users all over the world became very worried and bothered when the threat to Facebookcame from the world’s most notorious hacker group Anonymous. Today remarks the day, that was fixed by Anonymous to attack the social networking giant Facebook. However, in a post today, the members of the hactivist group expressed that they are very upset about the reports of Facebook attack and also claims that the treat was not real, according to CNET news.

According to the statement posted today, the hacker group does not take any movement that may not be accepted by the people. Their movements depend on communicating with people around the world so that they can help one another. “If you are against how we communicate on facebook, twitter, and anonops for example then you are against anonymous and become our enemy since you are trying to disrupt our movement. Because of this we decided to social the Opfacebook skiddy and hack him,” the post said.

“One skiddy queer chap named Anthony Guerra from the US in Ohio decided to take it upon himself to have some lulz with creating an imaginary opfacebook and pawning it off as a legit anon op. Despite us telling this mate several times we did not support his op, he continued to push his agenda for lulz. This op is phony but he continues to say it’s an anon op,” Anonymous said. According to the post, no one member is bigger than the group. No one can work without the help of the other members of the group. The writer of the post wrote about the member who wanted to do such an imaginary task and also gave the address and phone number at the end of the post.

A woman received the phone, number listed in the post, and said that someone with the name Anthony lives there but he was not involved with Anonymous, according to CNET reports. It is obviously a good news for the users of Facebook. Thanks Anonymous for not taking down our favorite social networking site Facebook.

Only one week passed after the release of the only authorized biography of the Apple co-founder Steve Jobs. However, within a week the book, entitled “Steve Jobs,” has become the 18th bestselling book of the year in United States, according to BookScan’s reports.

Simon and Schuster published the book, written by the former managing editor of Time Magazine, Walter Isaacson, on October 24, 2011. About 379,000 copies of the book have been sold in the United States in its first week on sale.

In the 656-page book, Walter mainly wrote about Job’s life and career and his cooperation in the modern technology. To complete the book, Walter interviewed a lot of people related to Jobs, both personally and professionally. He wrote both the bad and good sides of the late Steve Jobs that he found from the interviews.

The biography has beaten the next bestselling book of the week, John Grisham’s “The Litigators,” by more than three to one. It also outsold the third bestselling book, Bill O’Reilly’s nonfiction “Killing Lincoln” by more than eight to one.

We all know that there is no loss of energy in the universe. The energy only converts from one form to another form. The heat produced in our body is also one kind of energy that induced the form the energy of our food, but it is very low. This heat energy may be used, converting it into another form that is useful for our daily life. Some engineers of electronics company Imec in Belgium have developed a shirt, comprising with integrated devices, which can produce electricity from the heat induced in our body.

To create the newly developed shirt the researchers inserted Thermo Electronic Generator (TEG) that is entirely hidden in the shirt. The TEG consist of 16 thermopiles that mainly responsible to convert the heat into electricity. Two plates, one hot and one cold, are used to make a sandwich containing the thermopile. The thickness of the device is 5 mm. The voltage produced by the TEG is directly proportional to the temperature gradient across them. Ruud Vullers said that application of thermal gradient across two semiconductors produces a current flow between the semiconductors.

According to the developers of the shirt, the completely hidden TEG is capable to convert the heat of our body into electricity. The research results show that the devices can produce 1 mW power at 22 degree Celsius. Although, the produced electricity is very low in power, it can be used to run low-energy wearable electronic devices such as health-monitoring devices like electrocardiograms. The power rises to 2 mW when the user stands, and to 4 mW when the user walks.

Vullers said that they tried to integrate several devices into a shirt two years ago, but the shirt was not comfortable and also the devices were visible. However, the newly designed device has been integrated into an office style shirt and now the device is not visible from outside because the TEG has been significantly reduced in size. Besides, the shirt is far comfortable than the previous.

It’s a day of celebration in California in the United States after a renowned hospital in the area was able to successfully separate a conjoined two-year-old Filipino twins.

Doctors from the Stanford University Children’s Hospital successfully separated in a complicated nine-hour surgical operation sisters Angelina and Angelica Sabuco with the help of 400 people. Latest report state that the girls are now transferred to the intensive care unit, each with a scar stretching from her chest to her belly.

The tearful mother of the twins Ginady Sabuco was very grateful for the successful operation and thanked God and the doctors for doing the extra-ordinary medical procedure. Dr. Gary Hartman, the lead surgeon in the operation also expressed joy over the outcome of the operation and confident that the girls will have a smooth recovery after the operation.

“The long-term prognosis is that we should have a happy, healthy set of girls. We don’t see any barrier to a full recovery,” Hartman said. The girls along with their mother moved to the US last year to have the operation.

The twins currently live in San Jose California with their mother and 10-year-old brother. The girls were quite resilient in the operation which involves separating livers, diaphragms, breastbones, and chest and abdominal wall muscles. The twins are set to stay in the hospital in the next two weeks and could return home if everything will be okay and no complications will occur in these time frame.

They say eye is the most valuable organ in our body. The man who has lost the sight of his/her eye can only can feel how he/she is missing in the world. There are many treatments in medical science for the people who have lost their eyesight. Recently, some researchers from the Polenov Russian Neurosurgical Institute, Russia, and Institute of Medical Psychology, Germany, developed a new procedure for the treatment of blindness.

The new research and research result shows that non-invasive current stimulation has the ability to induce ‘neuroplastic’ changes in the brain and also improve the visual system structures. This is the main basis of the research.

The researchers treated 446 patients, who were blind because of nerve problem, with non-invasive repetitive transorbital alternating current stimulation (rtACS) for 10 days, which reduced the nerve lesions of the patients. Applying rtACS the visual field (VF) size was improved about 7.1 percent and 9.3 percent in the right and left eye, respectively, according to the result. The research report was published in the journal Brain Stimulation.

The lead researcher of the research Dr. Bernhard Sabel said, “We have shown for the first time that partial blindness can be reduced by a short-lasting therapeutic procedure using non-invasive electrical current stimulation.”

According to the result of the research, the rtACS improves the visual acuity and visual field size effectively. Because of some clinical and psychological requirements, the researchers are still working to get the clear result of the treatment.

The magician is a great wonder than a magic developed by him. Professional magician Simon Pierro is the wonder who has represented Apple iPad magically. He has created a special Halloween edition of his magical representation, blending his special brand of prestidigitation with wisely constructed digital wizardry.

After a hard working along with his helping hands, he has been able to surprise audiences with his new media magic tricks. Pierro said, “It was a hell of a lot of work” and he spent 10 weeks putting together this Halloween iPad acts. He also added, “Luckily my iOS programmer Masashi Beheim again joined the project. It took him more than 100 hours of programming this time, being as fanatical about details as I am”.

“I came up with the idea to tell a story about a killer and together with my magic colleague Thomas Fraps we decided to take the clown as the usual suspect,” Pierro said.

However, the background is not a short story of this wonderful magical representation, so obviously thanks to Simon Pierro to dazzle our eyes with a new magical device.

Copper cable, optical fibers, free spaces are mainly used as the communication path in the present world’s networking and information society. The conventional semiconductor lasers, used for the ever faster optical data transmission, have a maximum speed of 50 GHz. However, increasingly networking and the necessity of transmitting large amounts of data are the main obstacles of the speed over the transmitting path. Researchers all over the world are trying and researching to speed up the data transmission more and more. Recently, the researchers, of the Ruhr University Bochum (RUB) in Germany, have developed a new concept of ultrafast semiconductor lasers, called ‘spin laser’, which could inaugurate a new era to the high-speed data transmission for the Internet of tomorrow.

The Scientists of the RUB make intelligent use of natural angular momentum of electrons, called spin, to break the previous obstacles efficaciously. New spin-laser modulation frequencies can reach well above 100 GHz in the future. This is a crucial step for the high-speed data transmission in the future global networking.

In the spin lasers, the spin of the electrons are determined from the previous spin state, whereas, in the conventional technology, the spin of the electrons was randomly determined. The use of the electrons in the new model, forces the laser to work simultaneously on two laser modes with different frequencies. “This frequency difference can easily be tuned using the so-called birefringence in the resonator, for example by simply bending the microlaser” said Dr. Nils Gerhardt. Using these two modes in the micro-resonator can speed up the transmission rate upto 100 GHz, according to the news release of the RUB.

The researchers tested the new model and obtained their results in the collaborative research center 491 of the Universities of Bochum and Duisburg-Essen. The report of their research was published in the journal ‘Applied Physics Letters’ of the American Institute of Physics.

World famous social networking website, Facebook, is apparently making news again after a security expert had discovered a subtle programming error on their website code. This researcher, Nathan Power, who is works at the CDW consultancy firm apparently found out about a programming error on the website’s code which could allow a user to send a malicious code or a virus to another user, via its messaging option. This problem is a reminiscent of the May 2011 error which allowed all advertisers and app developers to access the personal information of the users, where no serious damage was caused in spite of all the fear it generated. However, Facebook as taken a long time to acknowledge this one as it has already been lingering around for a month.

According to a blog post by Power, this flaw allowed the user an option which would be just send an ERROR message under normal circumstances, due to the company’s policy on account privacy. After suspecting something out of place, Power than decided to investigate on his own by analyzing the POST request code, that was circulating in the servers. After a testing the code, he realized that by he could manipulate the POST request simply by typing a small message near the filename variable, thus allowing him to send an executable message or an attachment with relative ease. To put it in simple terms, this hole in the code can allow a person to send a potentially malicious or virus laden file attachment to any user, thus increasing the risk of the circulation of a harmful virus that can potentially damage the entire server, thus putting the private information of millions at risk.

In a surprising turn of events, the company officials merely brushed aside the error as a minor glitch. Ryan McGeehan, who is the head of the website’s security department, released a statement to the press valiantly claiming that such a glitch can only be misused if the perpetrator has some additional technical acumen that can allow him to bypass the website’s secondary security features. So, all we can do is hope that Facebook really does have the problem in control which means there is nothing to worry about.

Operations always put hurt on the body of patients, and particularly it is obvious for complex operations. Usually, the surgeons use 3D X-rays to observe the results of the operation in the operation theater. Although the use of the X-rays helps to detect any kinds of problem, it requires stopping the operations before using the usual X-rays technology. However, the German researchers have been researching to develop such a 3D X-ray system that will help the surgeons to check the operation complexity without any interruption.

The researchers of the Fraunhofer Institute for Production Systems and Design Technology (IPK) and Charité-Universitätsmedizin Berlin medical school have been working together to integrate the new 3D X-ray technology into operation. Maneuverability X-ray source is mounted on a hinged support that can be attached to the ceiling or mounted on a wheeled stands for mobile applications, so that X-ray scanning always takes place from above.

According to the researchers, the new technology will speed up the checking without interrupting whereas the usual ‘C-arm’ system takes about 15 minutes to produce the image of the checking results. Professor Dr. Erwin Keeve said, “Unlike existing three-dimensional imaging procedures, ORBIT doesn’t have to surround the patient to capture images. Instead, it’s an open system in which the X-ray source follows a circular path above the operating table. This makes capturing images much quicker, because it does away with time-consuming preparation.”

The new system is advantageous than the usual ‘C-arm’ system in many ways. It is very easier than the ‘C-arm’ technology because the surgeons need not to use various analytic tools in the operation theater. The images produced by the new technology are less affected by the interference of metals as its X-ray plate and detector move on different plane.

The prototype of the new 3D X-ray technology is under construction and its testing will be started in next year. It is expected that the 3D X-ray system will be ready for shipping in three to five years after.
