How to blacken gray hair back?

The age is identical to the growth of gray hair, but there are times when gray hair grow too early so that it can interfere with performance. Now the researchers team from several universities in Europe had found a formula to repel gray hair and restore hair color.

Through the scientific reports published online in journal of the Federation of American Societies for Experimental Biology (FASEB), at the end of April, 2013, the researchers revealed the gray hair growth process. Hair bleaching process occurs due to an accumulation of hydrogen peroxide and peroxynitrite in the hair follicle (hair root bag). Buildup of hydrogen peroxide happens due the hair follicles which damaged and broken.

The buildup of these chemicals eventually trigger hair color fading from the outwards core. It occurs because the hydrogen peroxide blocking the normal production of melanin, the pigment that responsible for color of our hair, skin, and eyes.

The research team had found the gray hair producers have compound that can be overcome by administering a topical compound called NB-UVB in the presence of PC-KUS. UVB alone is an ultraviolet light that can be harvested from sunlight.

"Our findings suggest the hair bleaching treatments can be improved," said Karin U. Schallreuter, researchers from the School of Life Sciences University of Bradford, UK.

This cosmetic treatment is also effective for vitiligo skin disorder. Vitiligo patients experience a loss of pigment in certain parts of the skin. Consequently, pale white skin appear on the body of the patient. In the United States, the vitiligo is suffered by 1 of 2 million people.

Gerald Wejssmann, editorial director of the FASEB journal, praised the findings. According to him, for the first time the problem of gray hair can be treated directly from the root of the problem. Moreover, these treatments can also treat the vitiligo.

"These findings could have an impact on the socio-emotional mostly because it can improve the quality of life," he said. Although it has been shown to be effective, researchers have yet to specify when this treatment is offered to the public. *** [EKA | FROM VARIOUS SOURCES | LIVESCIENCE | FASEB | MEDICAL NEWS TODAY | ANTON HILMAN | KORAN TEMPO 4223]

Waiting for the Legend rebirth

The trucks with great performance and pertained for the military purpose was so familiar in Indonesia. In 1950-1960's era, Mercedes-Benz that was sale into Indonesia not just limited to sedans, but also buses and trucks. Even mini-truck super tough, Unimog or Universal Motor Gerat.

Is it true that the water on Earth and Moon came from the same source?

Water in the Earth and the Moon apparently derived from the same source. The conclusion was obtained by a team of researchers from Brown University. "The water that comes to the moon and earth from primitive meteorites are now located in outer of the asteroid belt," said Alberto Saal, a geochemist who led the study.

This finding indicates that the water may have existed on Earth before the giant collision befall the planet and created the Moon. Giant Mars-sized protoplanet collision on Earth happened about 4.5 billion years ago. The heat generated has been baking all materials contained water on the Moon. Many experts call this planet has parched surface.

However, five years ago the first evidence of the presence of hydrogen found in lunar samples from the Apollo missions. Hydrogen is the main ingredient of water, along with oxygen. To find the origin of this water scientists analyzed the crystal and glass from moon rocks brought by the Apollo 15 and 17. Glass in the crystal is recorded the Moon geology history.

Researchers found the deuterium ratio of hydrogen in Moon rocks similar to those seen on Earth as well. Overall these findings suggest that the water on the Moon and Earth have the same carbon chondrites in the meteorites that found in the asteroid belt between Mars and Jupiter, which is considered one of the oldest objects in the solar system.

According to Saal, there are follow-up questions. If the water in the Earth and the Moon is there before the giant collision, why the heat were not make all the water dries. One possibility is that the evaporation of trapped gas in it, such as soda. This factor plus the Earth gravity, help the planet stay rich hydrogen and water.

The problem is, the Moon has a much lower mass, as well as gravity. Other scientists found water on the Earth may have come from comets. The researchers team from the Max Planck Institute for Solar System Research, Paul Hartogh and his colleagues have found that the deuterium ratio of hydrogen seen in comets is suitable to those found in the water contained in the Earth. If comets bring water to Earth, they may also be able to do so at a later date. *** [EKA | FROM VARIOUS SOURCES | SPACE | KORAN TEMPO 4228]

Is it true that the Mount Toba eruption trigger the human extinction?

Theory of mass extinction of mankind by the eruption of Mount Toba, which is categorized as a super-volcano, it is not entirely true. From the Recent research from the University of Oxford actually mention the impact of a giant volcanic eruption on the Sumatra island, it does not threaten human civilization.

Indonesia is itself now the site

A series of Toba eruptions at 75 thousand years ago was recorded as the largest super-volcano eruption in the last 2.5 million years. Mount Toba spew take more than 2,800 cubic kilometers of magma, equivalent to a mass of more than 19 million Empire State Buildings in America. Vomit Toba volcanic ash from spreading to the South China Sea to the Arabian Sea. For comparison, the eruption of Krakatoa which occurred in 1883 and is one of the largest eruptions in recorded history just spewed 12 cubic kilometers of magma.

As in one of the genetic studies have revealed that the number of modern humans at the time of the Mount Toba eruption is turned down drastically. Today existing human grown from a few thousand survivors of the disaster. "Researchers in the past suspected the human extinction caused by volcanic winter that caused by the Toba eruption," said Christine Lane, a geologist at the University of Oxford, on Thursday, May 2, 2013.

A super-volcano eruption could wreak havoc with the equivalent hunjaman asteroid. Vomit volcanic ash block out the sunlight and reflect it into space. As a result, the Earth became dark and cold this phenomenon is called "volcanic winter."

This theory is refuted by Lane and her team. Their research suggests that the Toba eruption was not destroy the human civilization. As the proof is the discovery of prehistoric artifacts in India. The artifacts from the period right after the Toba eruption suggests that humans are able to overcome the impact of the eruption. "Toba eruption did not significantly alter the climate," said Lane.

Now about a dozen remaining super-volcano that spread across several regions. Most of the giant volcano that is located on the seabed. *** [EKA | FROM VARIOUS SOURCES | HUFFINGTONPOST | MAHARDIKA SATRIA HADI | KORAN TEMPO 4221]

QUest for the Limits of LifE

Japan and Brazil are located on two different continents. One in Asia and another in America. Although the distance between the two countries reached more than 18 thousand kilometers, the urge to solve the lost continent mystery has led researchers team from the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) institute to Brazil.

The trees scream when they thirst

Water being one of the main factors mortal existence. In the dry season or when the volume of water is reduced, they felt the impact. The team of scientists believe they have made the first ever recording of a tree gasping for water.

Researchers used slivers of dead pine wood covered in hydrogel to recreate the conditions of a living tree. (Picture from: http://now.msn.com/)

So, just like the human voice while breathing, the tree also make an ultrasonic sounds. It happened because they attract moisture as much as possible to survive the dry season. Remarkably, the resulting sound turned out a hundred times faster than it can be heard by the human ear.

The scientists team led by France physicist, Philippe Marmottant from Grenoble University, believe that they have been able to slow down the process, so that the voice of the plant can be heard during the experiment in the laboratory.

They use dead pine tree wood slices are given a lot of hydrogels. Conditions are made ​​as similar as possible as the tree of life. The gel begins to dry out due to environmental influences. Here, the researchers listened to the wood like started making popping sounds. The noise comes from air bubbles rise, then disappeared. This process is called cavitation.

The trees create air bubbles through the effort of trying to pull in water from the ground through their root system. (Picture from: http://www.dailymail.co.uk/)

Like the leaves on the tree that collects carbon dioxide, they open up the pores, making it vulnerable to water loss. To overcome this, the trees take water from the soil through its root system. Efforts to attract water and the humidity of the soil creates air bubbles. "We can track the articulation bubble and what we found was mayorrtas audible sound associated with the bubble," said Marmottant, on May 2, 2013.

Majority the sounds appears there may be other causes, such as wood cracks or insect. However, most of the noise that occurs during cavitation is this bubble. Now, a team of researchers beriomba try with equipment capable of listening to the unique sounds created by nature. *** [EKA | FROM VARIOUS SOURCES | DAILYMAIL | ISMI WAHID | KORAN TEMPO 4222]
