For the first time in the world: It skull transplantation

Doctors in Texas have made partial transplants skull and scalp for the first time in the world, helping a man with a large head wound from cancer treatment.

Jim Boysen patient, 55-year-old - is expected to come from the hospital on Thursday, with a new kidney and pancreas, together with the scalp and skull transplanted, REL reports.

He said he was amazed at how the doctors had managed to find an organ donor with similar skin and color.

"It is somewhat shocking, really. I will have more hair than when I was 21 years old ", did Boysen joked in an interview with The Associated Press.

Last year, doctors in the Netherlands said they had replaced most of the skull of a woman with a plastic 3D printer to print.

Texas operation is thought to be the first transplant of a skull from a human donor, compared with an artificial plants are made.

Over the last decade, they are made transplants that were considered impossible to make.

More than 70 hand transplants have been done worldwide.

Last October, a Swedish woman became the world's first born child after a womb transplant.

A host of patients have received transplants or plants from body parts printed by 3D printers.

Lightning aircraft - new aircraft of US war (Video)

This week for the first time in American military participates Exercises "Lockheed Martin" with the F-35 Lightning fighter aircraft (lightning), Which is Another Step in the Development of the program's Biggest Weapons Pentagon Officials have announced US War Aviation.

The exercise Named "Green Flag West" is intended testing of the US military's Ability to participate in air-land Conflicts and to help ground Troops preparing for war.

Three Types of aircraft "F-35 Lightning with variants A, B and C are Designed and developed in" Lockheed Martin "in Texas, Reports 

Some Types of model A, with aircraft Other Weapons Will Also participate in the Exercises.

Gen. Herbert Carlisle, Commander of the air action, Reuters Told That the Exercises are Important BECAUSE of the global real war scenarios.

"It is Extremely Important to spend beyond theory to access dynamic soft ... Which region Changes continuously," Said Carlisle.

He added modus That US aviation aircraft USED previous Exercises Prepared by the sponsors of the F-35, and now is the first time the aircraft BEING USED That "Operational more representative."

Said Carlisle That fighter aircraft works on solving Still Some Problems on the way of Transmission of information to the pilot WHO come from Different radar sensors.

He expects to swear up during Exercises Successful aircraft.

It is Expected That the plans of the US military in July to PUBLISH the order of ten F-35B supersonic ready for use.

F-35 program is worth more than 400 billion dollars.  

Forget the batteries, the handset will soon fill with boiling

Say goodbye to batteries and by filling power. Very soon we will be able to use Wi-Fi to connect to other devices and to have the batteries forever in our mobiles.

You will not need to fill in your phone to send a message and also will not have to stand on a chair to get the best signal.

All these will be part of the past, because American engineers have recently designed a technology that interacts with Wi-Fi signals and turns them into energy. They have created a prototype modem for this job.

During tests, these so-called PoWiFi modems supplied cameras without batteries from five meters away and to do so without interfering with Internet speed line owners.

The technology was first introduced by researchers at Washington University, but the main engineering, Shyam Gollakota, recently demonstrated a prototype Digital EmTech conference.

His team installed a modem PoWiFi in six home and asked the Gods to use the Internet as usual for 24 hours.

Technology makes it possible for two devices to communicate without batteries using wave signals.

PCs powered by radio frequencies are small devices that operate and communicate using the energy received from the radio frequency signals.

Modem used in tests conveyed radio waves which were converted into a direct voltage by using what is known as a 'refiner. This is similar to how solar panels convert light energy into electricity.

A DC-DC converter was then used to increase the voltage level signals to match the requirements of the sensor or microcontroller.

Technology is not the first that uses energy from sources of radio frequency environment, but it is the first that does not require a dedicated gateway to connect to the web.

More specifically, the team reuse the existing infrastructure of Wi-Fi to provide about these low power devices. And as uses radio frequency signals to the environment that are already around us, it does not require a dedicated infrastructure to strengthen power.

Users experimental homes said that they saw no significant change in their Internet experience, during the operation of charging the phone through Wi-Fi.

The researchers explained that the modem can empower a camera without the battery up to five meters away from the modem. Also it reinforced a temperature sensor without batteries.

In the study team called "To empower billions of devices with Wi-Fi", the researchers said, there is a growing interest in the things of the internet, where small sensors and mobile devices are embedded in everyday objects and the environment.

A key issue is how to strengthen these devices as becoming smaller and more numerous. The new system uses energy delivery Wi-Fi chips and minimizes the impact on network performance Wi-Fi.

Scientists claim to have made the first prototype of temperature sensors and cameras without batteries to receive electricity with Wi-Fi. "We also showed the feasibility of filling the wave of mobile phone batteries with nickel metal hybrid and lithium ion", said the scientists.

Over time, the technology could lead to network devices and sensors that send data reflecting the current signals to exchange information without the need for batteries. For example, everyday objects can be used to communicate with each other. Thus, it can be used to help users know where they leave the house keys.

Intelligent sensors can be built and placed permanently in each structure, then they can communicate with each other. This may include a bridge that monitors performance and leading alerts if one of the sensors picked up anything that is wrong.

Last year, researchers tested the technology with prototype equipment to the amount of credit cards placed inside each other. For each device, the researchers built antenna in common circuit boards that provide a light when receiving a communication signal from one device to another.

Groups of devices tested in a variety of configurations in the Seattle area, including an apartment, a street corner and a high-level garage. These locations ranging from one kilometer from a television tower up to 10 kilometers. They functioned thus giving hope to soon be saved from the charger and chips can get new energy for mobile phones and other technological devices through the waves.

DNA discovered biological clock

American scientists have discovered the biological clock based on DNA, which measures the speed of the aging of tissues and organs in our body.

This hour shows that the majority of old tissue with the same speed as the whole body, but there are parts of the body aging more quickly or more slowly. Diseased organs, for example, can be up to ten years "old" rather than sound and organs in the same body.

The team of researchers from the University of California at Los Angeles (UCLA) believes that deciphering the mechanism of work of this ore would enable scientists to better understand the aging process, and thus also come with medicines and therapy new which could slow down aging.

"It would be very interesting if we developed new therapies that will" reset "the clock and keep us younger longer," said team leader Steve Horvath, a professor of genetics and biostatistikës.

In a study published in the journal "Genome Biology", US researchers stressed that they had examined the DNA of 8,000 samples from 51 healthy cells and tissues and cancer. In particular, they analyzed how methylation, a natural process that chemically modifies DNA varies with age.

Horvath and his colleagues concluded that methylation of 353 DNA markers changes continuously during aging, and it can serve as a biological clock.

Flap time soon until the age of 20 years, and then slows down. So far it is not known whether changes in DNA that cause aging or are in fact a consequence of aging.

"The appearance of gray hair is a sign of aging, but no one would say that what causes aging," said Horvath.

Research so far has led to interesting results. Tests on healthy heart tissue showed that there are about nine years "younger", as breast tissue was older than the rest of the body, in an average of two years.

Diseased tissue aging at a different pace. Cancer, for example, the clock speeds by an average of 36 years.

Horvath study also showed that the biological clock can return to zero when the cells of an adult stem cells reprogrammed through.

The conversion process cells, adult stem cells similar, which found John Gurdon of Cambridge University and Shinya Yamanaka of Kyoto University, was awarded the Nobel Prize last year.

"This concept is evidence that the return back the biological clock is possible," says Horvat, the next step of which is the study of how neurodegenerative and infectious diseases affect the biological clock and vice versa
