Scientists first measure the length of a day on a … – Terra Peru

know more and more and meet some of them habitable, but now a Dutch team has for the first time to measure the length of a day Beta Pictoris exoplanet in eight hours, using the Very Large Telescope located in Chile.

Exoplanets are those planets outside our solar system identified an area where there have been increasing in recent years discoveries : NASA in February estimated that there are 1,700 identified and more recently the discovery of the first exoplanet about the size of Earth where liquid water exist was confirmed, which would potentially habitable

A team. Dutch astronomers at Leiden University and the Institute for Space Research of the Netherlands (SRON) is achieved using the Very Large Telescope (VLT) on Cerro Paranal Chile, measure the length of a day on one of those exoplanets :. a day in the Beta Pictoris b runs in just eight hours

Scientists estimated that the largest Ecuador on this planet 16 times and with a mass 3,000 times that of Earth rotates at a speed of 100.000 mph, extremely fast compared to 17,000 kilometers per hour traveling to our planet and only comparable in the Solar System 47,000 kilometers per hour on Jupiter.

The relationship between mass and confirm the observed rotation to do exoplanets extended to conditions in the solar system, which could be related to the formation of planets.

“It is not known why some planets move faster and others more slowly, “said Remco de Kok, co-author of study published in the journal Nature on Wednesday,” but this first step of the rotation of an exoplanet shows that the trend seen in the solar system, where the most massive planets orbit faster can be applied to exoplanets. “

” There must be a universal consequence arising from the way the planets are created, “he added.

Beta Pictoris is a very young planet , only 20 million years, compared to 4,500 million earth, and is expected to grow as more cool and shrink, which would make rotase even faster.

Researchers were able to determine the rotation of Beta Pictoris b, a star formed by giant gas discovered in 2008 orbiting the Pictoris star located 63 light years of Earth, using a technique called spectroscopy.

The results of this research could lead to a detailed map of exoplanets, mass and specific conditions in the future.

“Now we know from this study that Beta Pictoris b is certainly not a planet a brown dwarf (often known as failed stars), so now this assumption is not used, “said for his part AFP Dimitri Mawet, an astronomer at the European Southern Observatory (ESO) who also works with the VLT.

“We have very important steps and serve to refine the model of the atmosphere of this planet (…) that will be the basis for others and understand how they are formed.”

Mawet said it is the first time that the rotational speed is shown. “It will allow us to have statistics and learn about the formation of the planets and their rotation speed, and also on the conditions of its surface. This opens the door to many exciting discoveries in the future.”

Yoshida: Virtual reality not start – LevelUp

In an interview with a U.S. news site last April 29, 2014, the president of Sony Computer Entertainment Worldwide Studios, Shuhei Yoshida said that the current state of virtual reality is the same as the graphic 3D on the PlayStation, meaning we will not see its full potential in this generation

During the interview, the manager said about the early days of the PS. “people were not sure how the 3D graphics could be used for games. Some people in the major Japanese distributors were very skeptical regarding 3D technology. But after 20 years things have really progressed. We amazing games like The Last of Us or Beyond Two Souls , which renderean real-time a variety of things in 3D. “

Yoshida also noted that virtual reality is still in early stages and has a lot where grow. “He has not even really begun. When we launch Project Morpheus or the Oculus [Rift] out for consumers, I can see another 20 years of progress in them. I feel it is as it says Mark Zuckerberg (founder of Facebook), sees a future vision of what this might be, rather than the first or second year. “

The executive also said that his virtual reality device , Project Morpheus, is very similar to Nintendo Wii U in the sense that offer asymmetric gameplay. He said that some games will allow the user to put the team on his head, while others can interact with it using a traditional screen. He compared it to Mario minigame Chase , Nintendo Land , in which a player uses the screen gamepad to flee to other 3 users, who use television to look.

Sony officially revealed Project Morpheus this year’s Game Developers Conference. The virtual reality equipment has 3 years in development and includes a 5” LCD screen, a field of view of 90 degrees, an accelerometer, a gyroscope and audio support.

Both Sony and Facebook say they will not seek to compete with each Both Sony and Facebook say they will not seek to compete with each other

Scientists create first synthetic chromosome – The Nation Costa Rica

Washington and Paris. AFP and EFE. A team international scientists created the first chromosome completely made in a laboratory from yeast.

The achievement is considered a great find in synthetic biology, which seeks to design agencies since its inception most basic, indicate two articles in magazines Science and Nature .

had already managed to build chromosomes of bacteria and viruses, this is the first time a chromosome to a eukaryotic organism, which are more complex is created (they are composed of cells with distinct nuclei and organized cytoplasm).

Thus, the first synthetic chromosome Tsar allow advanced research to produce new medicines and biofuels.

Scientists led by Jef Boeke Langone Medical Center University of New York, made the first artificial copy of a yeast chromosome.

The research was input from scientists in the U.S.. UU. and Europe and took over seven years.

In the process, the scientists were able to cut, split and manipulate DNA of yeast used to make beer until the first chromosome made entirely a laboratory.

Boeke began research at Johns Hopkins in Baltimore, and with the collaboration of his students to make the daunting task of creating this genome, which required 273,871 join base pairs of yeast chromosomes. This amount is less than its natural counterpart whose genome has exactly 316,667 pairs.

The scientists began with the DNA fragments available and were added to other majors. Later added to yeast cells so that finally succeeded in producing a totally artificial version of the chromosome.

This was due to the team of specialists made alterations in the genetic basis of This DNA, including the elimination of redundant portions of the chromosome for reproduction and growth.

The eukaryotic chromosome (a structure containing the genes in the nucleus of cells of all plants and animals), which experienced unprecedented changes, then joined live yeast cells.

latter behave normally, but have new properties that do not have natural yeast, stressed the researchers, who recalled that the yeast has a total of 16 pairs of chromosomes, while humans have 23 pairs.

Once completed the experiment, Boeke said the entire chromosome was “amazingly normal” and that the yeast with synthetic DNA “You behaved almost identically to natural yeast cells.”

An extrasolar giant planet with a day that lasts only eight hours – País.com (Spain)

id=”cuerpo_noticia”> From extrasolar planets, in addition to discovering more and more every day, astronomers are observing new features ever more precise data which not long ago seemed impossible to obtain but are accessible resulting with advanced telescopes and ingenious strategies cameras observing scientists. The latest development is the direct measurement of the length of day in a giant extrasolar planet who meets a complete rotation on its axis every eight hours. It is a gaseous body discovered six years orbiting Beta Pictoris, a star located about 63 light-years away from Earth. To get an idea of ​​how quickly the body turns blue, and the brevity of their day-just compare their speed (100,000 kilometers per hour in Ecuador) with the Earth (1674.4 kph) and Jupiter (47,000 kilometers per hour measured in the equatorial atmosphere).

Beta Pictoris b, the planet as it is called, is much larger than Jupiter, with a radius of 1.65 times and a mass 10 times greater; compared to the Earth, is 16 times more massive 3,000. It is still very young (about 20 million years, compared to about 4,500 million years of our planet) and hot, so astronomers expect that, as cool and shrink, increase its rotation (for conservation of angular momentum, the same effect that makes a skater spin faster on himself when his arms about the body), explains the Observatorio European (ESO) , which together with VLT telescopes in Chile, astronomers have been able to take new measures Beta Pictoris b. Ignas A. G. Snellen ( University of Leiden , the Netherlands) and colleagues presented these new data on extrasolar planet magazine Nature.

“No one knows why some planets spin faster and some slower, but this first step of the rotation of an exoplanet shows that the trend observed in the solar system, where the most massive planets spin faster, it is also true for extrasolar; should be a universal consequence of the way in which these bodies are formed, “says Remco J. de Kok, one of the astronomers of the team. Yes, in the Solar System, “escape from this trend Mercury and Venus, significantly slowed due to gravitational interaction with the Sun and other disturbances,” said Travis Barman, an expert from the University of Arizona , commenting Nature about the discovery.

Beta Pictoris b is an extrasolar planet known to astronomers. Discovered six years ago, was one of the first to be able to shoot straight. Its star is about eight times the distance between Earth and the Sun

In his observations accuracy Snellen and his colleagues have used the technique of spectroscopy to separate the light from the planet in their constituents, different wavelengths, and are based on Doppler color (wavelength seemingly stretches is or shrinks depending on whether the issuer or away About observer) to measure how different parts of the world move at different speeds and in different directions. So they have managed to extract your data signal the planet’s rotation. “We measured the wavelengths emitted by the planet with an accuracy of one part in 100,000,” says Snellen. “With this technique we have found that different parts of the planet’s surface are moving to or from us at different speeds, which can only mean that is rotating around its axis.” The astronomer added that this observation technique can be applied in many more extrasolar planets with high resolution will the future European giant telescope E-ELT.

All the knowledge you are gaining on extrasolar planets allow unravel formation processes of planetary systems in the universe. “The rotation of the planets is something we notice every day on Earth to rise and set in the sky the sun, moon, planets and stars” recalls Barman. “Of the planets in our solar system five rapidly rotating in the same direction as they orbit around the Sun; is unlikely to be by chance and reflects important but poorly understood how planets form aspects, “adds the scientist from the University of Arizona, emphasizing the importance of this research.
