Superfast laser kills Viruses

A physicist, biologist and son destroyed a common virus with a vibrant super lasers, but not healthy cells. The discovery could lead to new therapies for the treatment of viruses such as HIV, which are not healing.

"We have a technique, using a laser to seduce the vibrations of the armature of a virus and damage, so it will not be the` more operational, "said Kong Tsen, professor of physics at Arizona State University. "We are testing again on HIV and hepatitis now."

Tsen Shaw and his son-Wei Tsen, pathology students at the Johns Hopkins University, came to the idea while strolling in the park, and the need for antiretroviral therapy, beyond vaccination . Tsen Senior experimented with ultra-long laser pulses (universal service), devices increasingly outside of physics.

Raydiance, a manufacturer of laser USP, has signed a contract with the FDA in July to explore laser therapies. How Wired News reported in the year, an official estimate from the FDA, it could be cent for medical applications USP Laser, Laser eye of the cell treatment by the removal of the tumor cells.

In the latest research, and his son Tsen showed that their techniques laser could destroy the protein shell or Kapside, mosaic virus tobacco, and leaves only harmless mucus hardening of molecules.

The laser is broken, Kapside low power consumption: 40 times lower, in fact, that energy, that the human T lymphocytes damage. Other types of radiation, such as ultraviolet rays, to kill microbes produce, but would harm human cells.

The virus can disable laser operates on the principle of resonance forced behalf. Scientists agree the laser on the same frequency, the virus vibrates. Then, until the crank to reduce the volume. Since much ohrenzerreißende his shaken the glass vibrates lasers, the virus until it breaks.

Lasers USP Releases energy Femtosekunden-Pulsen -- millionth of a nanosecond -- for a while.

"The extremely short pulses to the creation of a physical effect that the traditional lasers, and other types of approaches makes laser` t do, "said Scott Davison, president of the USP Venture Backed laser Raydiance. "What we are seeing is a new wave of exploration and discovery in implementing USP in a range of sectors and applications."

Unlike meat blow in laser surgery laser USP Don `Umsatzesaus much heat. Tsen said, the technique could be useful for the immediate removal of viruses in the blood in blood banks. Some viruses, such as HIV, have a window in which it is very difficult to detect.

"This technique is very useful to disinfect all viruses, known and unknown, Tsen said." That would be the very safe blood transfusion. "

The Tsens `success of the technology has been in test tubes. It must be examined in animals and then humans. Salaries are even further in the future. But with more walks in the park, everything seems possible.

Mysterious object Belmez!

In belmez de Los Angeles moraleda, Spain, sits in the Pereira family home, scene of the strange events that have lasted for more than 30 years. The events that began in 1971 when Maria Gomes Pereira seen strange to form burner of her kitchen. It looked like a human face, so that Maria's husband took Ax and destroyed burner, and it was planted with new cement. A week later appearing in the new floor. The family asked the city council to investigate and after weeks of digging a hole and found containing human bones under the direct burner. The pit was filled and developed new burner, but within weeks more faces began to emerge again. Whatever the Pereira family tried to destroy them, and the object returned. For thirty years the faces have visited by scientists, researchers and countless television crews. It is believed many of the faces were faked and that has been painted. But a thorough examination of the burner that showed the faces were painted cement instead of the highest. This seemed to prove that the phenomenon is real and one of scientists announced that it was "without doubt the most important Paranormal phenomenon of this century."

Tut Mummy on Public Display for First Time

The mummy of King Tutankhamun today went on public display for the first time—85 years to the day since his tomb was discovered in Egypt's famed Valley of the Kings.

Until now the boy pharaoh's remains had rested in his sarcophagus in the burial chamber of the tomb, which lies just north of the city of Luxor.

But on Sunday morning the remains—settled inside a wooden box—were carefully transferred to a high-tech glass display case about 30 feet (9 meters) away in the tomb's antechamber.

The valley was frenzied with TV camera crews, photographers, and journalists, who converged below the gravelly sun-drenched hills near the tomb.

The atmosphere seemed fit for a modern-day movie star, underscoring the enduring celebrity of a king who died more than 3,000 years ago.

The move will help preserve Tutankhamun's mummy, which experts say has been deteriorating rapidly because of exposure to heat and humidity.

The new display is also expected to increase visits to the tomb from about 350 to 900 tourists a day, generating funds for the protection of Egyptian antiquities.

"I can say for the first time that the mummy is safe, the mummy is well preserved, and also at the same time, all the tourists who will enter this tomb tomorrow morning will be able to see the face of Tutankhamun for the first time," said Zahi Hawass, secretary general of Egypt's Supreme Council of Antiquities and a National Geographic Society explorer-in-residence.

8-Foot Giant Catfish caught in Cambodia

Captured just before midnight on November 13 by fishermen in Cambodia, the Mekong giant catfish was 8 feet long (2.4 meters long) ands weighs 450 pounds (204 kilograms).

"This is the only giant catfish that was so far this year, making it the worst year on record for catching fish species giants," said Zeb Hogan (right), a fisheries biologist at the University Reno in Nevada.

After collecting data on fish, Hogan released unharmed.

Siluro giant once were abundant throughout Southeast Asia, the Mekong River Basin, including the Tonle Sap River-home of the fish in these exclusive pictures taken near Phnom Penh.

But in the last century, the giant Mekong catfish population has declined by 95 to 99 percent, scientists say. Only a few hundred adult giant catfish can stay.

Since 2000 five to ten fish have been caught accidentally every year across the Mekong area.

Earlier this year, Hogan launched the three-year period Megafishes Draft paper by world giant freshwater fishes (See photos of other giant fish.)

Satellite captures Earth 'rising' and 'setting'

Series of five images of the Earth 'setting' as seen from the Moon - taken by the Kaguya probe.

A Japanese satellite has captured the first high definition images of the Earth from the moon.

Footage taken from 62 miles above the lunar surface shows the most-detailed yet pictures of an "Earth-rise" and "Earth-set" above the moon's horizon.

Still photographs from the sequences show our planet in brilliant blue with Antarctica at the top, Australia in light brown on the left and the Middle East in the lower right section.

The images were taken last week using a high definition (HD) television camera, developed specially for use in space by the Japanese national broadcaster NHK.

This was mounted on Kaguya, a Japan Aerospace Exploration Agency (JAXA) probe which is carrying out the most extensive investigation of the moon since the Nasa Apollo missions.

Earth-rises and earth-sets can only be seen from satellites travelling in orbit around the moon as our planet is always seen in the same position from the lunar surface.

The Kaguya probe, named after a princess in a Japanese fairytale, was around 240,000 miles from Earth when it captured the footage.

The first ever image of the Earth was taken in 1959 by the US satellite Explorer VI while it was passing over the Pacific Ocean.

Kaguya, which launched in mid-September, will produce high resolution surface and gravity maps, observe lunar magnetic fields and search for water ice during its one-year mission.

Japan has been expanding its space operations, and has set a goal of sending an astronaut to the moon by 2020.


The onboard high definition camera of the moon explorer "KAGUYA," which is under initial functional verification, successfully acquired the world's first high definition images of an "Earth-rise" and "Earth-set." It was also the world's first HD images of the Earth from about 380,000 km away in space.

Indian man marries dog to beat 'curse'

An Indian farmer has married his dog in a bid to overcome what he believes is a curse caused by him having stoned to death two mating dogs in his rice field, press reports said.

Doctors were clueless, but an astrologer finally told him he was cursed by the spirits of the dogs he had killed. He could undo the curse only if he married a dog and live with it, the soothsayer said.

After a long search for a 'suitable bride', Selvakumar managed to get a four-year-old mongrel bitch from a friend and had a fully-fledged Hindu wedding in front of villagers and elders on Sunday, eyewitnesses said.

The canine bride, named Selvi, was adorned in a sari and flowers and brought to the temple by village women. A Hindu priest conducted the ceremony.

The reports, however, said Selvi the dog attempted to make a run for it -- apparently due to the large crowds -- but was eventually tracked down and returned to her new 'husband'.

"The dog is only for lifting the curse and after that, he plans to get a real bride," a friend of the groom said.

Six-legged frog is star attraction

A Chinese restaurant has found a six-legged frog - and is keeping it to attract diners.

The frog is on display in a glass tank at the restaurant in Quanzhou city, reports People's Daily.

"I bought more than 5 kilos of frogs from the market the other day, and upon coming back found that one of them has six legs," says chef Xiao Song.

The frog has two extra legs on the front left side which, according to waiters, means that it has a lopsided hop.

Experts at the local forestry department say the extra legs were most likely caused by genetic mutation.

Article~Time Dilation

The special theory of relativity describes how motion affects measurements of time and distance. Einstein concluded that these measurements must depend on how the person making the measurements is moving. The basis of this theory is that all people, whether moving or stationary, must agree on certain basic physical phenomena, especially those involving the behavior of light.

Imagine that you are standing on the Earth while our friend is traveling across our solar system at a high speed, as shown in the accompanying sketch. You set off a flashbulb that emits sudden bright flash of light. The radiation moves away from you at the same speed at all directions, and thus you see an expanding spherical shell of light. What does your high-speed friend see?

Einstein argued that this person must also see light moving away from her at the same speed in all directions, and thus she also sees an expanding spherical shell of light.By requiring that both people observe a spherical shell, Einstein derived a series of equations to relate specific measurements of time and distance between two people. These equations are named the Lorentz transformations, after the famous Dutch physicist Hendrik Antoon Lorentz (a contemporary of Einstein who developed these equations independently but did not grasp their true meaning.) These equations tell us exactly how a moving person's clock slow down and how rulers shrink.

To appreciate the Lorentz transformations, again imagine that you are on Earth while a friend is moving at a speed v with respect to you. Suppose that you both observe the same phenomenon on Earth - say, the beating of your heart or the ticking of your watch, which appears to occur over an interval of time. According to your clock (which is not moving relative to the phenomenon), the phenomenon lasts for T0 seconds. This is called the proper time of the phenomenon. But according to your friend's clock (which is moving relative to the phenomenon), the same phenomenon lasts for a different length of time, T seconds. The Lorentz transformation for time tells us that these two time intervals are related by:

Lorentz transformation for time





T = time interval measured by an observer moving relative to the phenomenon
T0 = time interval measured by an observer not moving relative to the phonomenon
v = speed of the moving observer
c = speed of light

EXAMPLE: Suppose that your friend is moving at 98% of the speed of light. Then, v/c = 0.98 so that

=> T = 5T0




The Lorentz transformation for time is plotted in the accompanying graph, which shows how 1 second measured on a stationary clock is stretched out when measured using a clock carried by a moving observer. Note that significant differencesEXAMPLE: Fast-moving protons from interstellar space frequently collide with atoms in the Earth's upper atmosphere. When they do, they can create unstable particles called muons (pronounced "mewons") that decay in an average time of 2.2 x 10 to power -6 seconds. Such muons typically move at 99.9% of the speed of light and are formed at an altitude of 10kn. As measured by an observer on the Earth, the time that a muon would take to reach the Earth's surface is




This is 15 times longer than the life expectancy of a muon, so it would seem that muon would never reach the Earth's surface before decaying. In fact, these muons are detected by experiments on the surface! The reason is that as seen by an Earth observer, the muon is a "moving clock", and hence its decay is slowed down by time dilation. To an Earth observer, the actual lifetime of a muon is



Thus, as measured by an Earth observer, muons live more than long enough for them to reach the surface. The detection at the Earth's surface of muons from the upper atmosphere is compelling evidence for the reality of the time dilation.
