For the first time, a vaccine is successful to defeat Ebola – lanacion.com (Argentina)

LONDON For the first time, the world is about to be able to protect humans from Ebola, said yesterday the World Health Organization (WHO), after the results of a test in Guinea showed that a vaccine is one hundred percent effective.

Initial results of a study that evaluated the immunization of Merck and NewLink Genetics called VSV-ZEBOV more than 4,000 people who had been in direct contact with a patient with confirmed diagnosis of Ebola showed 100% protection after ten days.

The data were described as “exceptional” and “revolutionary” by specialists in global health. “We believe the world is about to have an effective vaccine against Ebola,” said the expert WHO immunization Marie Paule Kieny, at a press conference in Geneva.

The vaccine can now be used to help end the worst Ebola outbreak on record, which killed more than 11,200 people in West Africa since its inception in December 2013 is taken.

For years, scientists try to develop treatments and vaccines for Ebola, but they face many obstacles, including the sporadic nature of outbreaks.

The Director General of WHO, Margaret Chan, said the study results , published in the online edition of the medical journal The Lancet, was an “extremely promising development”.

“This is going to be revolutionary,” Chan told reporters. “It will change the handling of the current outbreak of Ebola and future outbreaks,” said

This and other trials of experimental immunizations were accelerated with a huge international effort., As researchers strive to achieve test potential therapies and vaccines at a time when the virus is in full circulation.

“We knew it was a race against time and the trial had to be implemented under the most challenging circumstances,” says John-Arne Rattingen, chief control of infectious diseases at the Norwegian Institute of Public Health and president of the group that led the trial.

The trial in Guinea to assess the effectiveness and safety of the vaccine began on March 23. a single dose of VSV-ZEBOV was tested using the strategy of “ring vaccination” in which people close to someone diagnosed with Ebola were immunized either immediately or a few days later.

As they began to emerge data showing a high rate of protection among vaccinated immediately, researchers on July 26 decided to no longer use the strategy “delayed” because it began to be clear that waiting involved unethical and unnecessary risk.

The trial continues and all participants receive a dose of the vaccine immediately. It will be extended to include children of 13-17 years and possibly to less than 6-12 years, WHO said.

“Our hope is that the vaccine now will help us end this epidemic [in Africa] and prepare for the inevitable future epidemics of Ebola, “said Jeremy Farrar, infectious disease specialist and director of the Wellcome Trust charity.

Doctors Without Borders, who led the fight against Ebola in West Africa, is asking that VSV-ZEBOV be applied in other epicenters of the current outbreak, Liberia and Sierra Leone, where they believe could cut the chains of transmission and protect health care workers.

For its part, WHO will now take charge of the fight against the virus after yesterday closed the Mission of the United Nations Emergency Response against Ebola.

“We have made progress considerable, but the crisis is not over, “he said, for his part, Secretary General of the UN, Ban Ki-moon to announce the closing of the mission.

The installed emergency mission last September in response to the slow response of WHO to disease and lack of coordination among various aid organizations.

Although new infections in Guinea, Liberia and Sierra Leone since the beginning of year fell sharply, still has not overcome the virus. A single infected person is enough to sprout again the epidemic.

Tonight the moon will be appreciated with gray and silver tones – El Diario de Yucatan

         

     

Mexico, July 31 (Notimex) .- A glance and from any part of Mexico, you can appreciate the Friday night “Blue Moon”, a phenomenon that occurs every three years.

The Institute of Geophysics of the National Autonomous University of Mexico (UNAM) said that contrary to its name, the moon is not blue, the term indicates that you can see the star filled two phases in the same month.

Because the lunar cycle is 29.53 days, after the first full moon falls at the beginning of the month is likely to be perceived as follows at the end and in gray, white or silver.

The first recorded use of the term “blue moon” dates from 1524, which referred to the third stage in a full season within which fell four full moons instead of the three that regularly occur in one season .

However, in 1946 when the term gets a new interpretation through an article in the US magazine Sky & amp; Telescope, which is called “Blue Moon,” the second full moon that falls within a calendar month.

It is reported that after forest fires or volcanic eruptions, the moon takes a slightly blue hue as ash particles that they are released generate the moonlight, passing through the Earth’s atmosphere, look for that color.

This phenomenon was seen after the eruption of the Krakatoa volcano in Indonesia in 1883 and Santa Elena, located in the United States in 1980 and Chichon in Mexico in 1983, among others, however, has nothing to do with the definition of blue moon.

The last “Blue Moon” occurred on August 31, 2012 and after tonight will be charged, will have to wait until January 2018 to return to see the next

Facebook presents drone to bring Internet to the world – The Economist

announced two developments to provide Internet connectivity to more than 4,000 million people lack access to the network.

Facebook announced two progress to provide Internet connectivity to more than 4,000 million people lack access to the network, which has been their mission since they launched internet.org.

In this way, the team Connectivity the company run by Marck Zuckerberg presented his drone named Aquila, powered by sun and capable of flying for 90 days at an altitude of 18.000 to 27,000 kilometers energy.

In turn, it has a frame carbon fiber and unique design, this UAV can reach remote areas to provide connection.

The company also introduced a laser that can deliver data 10 times faster than currently possible and only aim at a target the size of a penny provides Internet 10 kilometers away.

Today the firm continues with laser testing under real conditions and when the system is completed, may be used to connect the aircraft with one another and with the ground.

This, he said, would create a stratospheric network that can extend to the farthest regions.

Ebola vaccine 100% effective after first trial – The Economist

The first results, published in the British medical journal The Lancet, show that VSV-ZEBOV vaccine demonstrated an efficiency of 100% in the first 10 days for a clinical trial on the ground in Guinea, in more than 4,000 people.

A vaccine against Ebola virus was found to be 100% effective in a clinical trial on the ground in Guinea, more 4,000 people, announced on Friday July 31 the main participants in the project.

“An effective vaccine against the Ebola virus is to reach globally,” he said in a statement the Organization World Health Organization (WHO), which spoke of a “very promising development.”

The first results, published in the British medical journal The Lancet, show that VSV-ZEBOV vaccine demonstrated efficacy of 100% in the first 10 days after administration in an uninfected person but contact with the sick.

The vaccine was developed by the Public Health Agency of Canada (PHAC) and the license was filed by US Merck and NewLink Genetics Corp. The trial was made possible by a major international cooperation in the WHO and experts from Norway, France, Switzerland, USA, UK and Guinea participated.

“If the results are confirmed, this new vaccine could it be the miracle cure for Ebola, and help stem the current epidemic and curb similar epidemics in the future,” he said for his part Borge Brende, Norwegian Minister of Foreign Affairs.

The current Ebola epidemic, which broke out in Guinea in December 2013 and is the most serious in West Africa since the virus was identified in 1976 in central Africa, left 11,279 dead between 27.748 cases, a balance WHO considers even underestimated.

The VSV-ZEBOV vaccine is one of the two most advanced vaccine against the Ebola virus. The other, developed by the British firm GSK (GlaxoSmithKline) and the American Institute of Allergy and Infectious Diseases (NIAID), it is currently being tested in Liberia.

Tonight will be a “Blue Moon”, which happens every three years – RPP News

Friday, July 31, 2015 | 8:34 a.m.

On Friday, last day of July can be seen in the sky a “blue moon” , which occurs approximately every three years and that will not happen again until January 2018.

As noted by the Naval Observatory US on its website,

called “Blue Moon” the second full moon in a calendar month , July in this case.

Each lunar cycle lasts approximately 28 days, so when a full moon occurs at the beginning of the month it is likely to be a second at the end.

That’s what will happen this July, which had its first full moon Day 2 and will have a second, “Blue”, on Friday 31st.

“Blue Moon” is called but not be that color, but in shades of gray, white or silver , which is normally seen in the satellite.

According to experts, the moon has been dyed blue rarely, the effect of dust, ash and smoke into the atmosphere because of large volcanic eruptions or forest fires.

The last “blue moon” occurred on August 31, 2012 and for the next after this Friday, it will be necessary wait until January 2018.

Philae organic compounds found in comet – Televisa News

WASHINGTON, EU., July 30. 2015.- The Philae module which made history last November to successfully land on the comet 67P, found organic compounds considered precursors of life, reported the American Association for the Advancement of Science (AAAS).

The association today published a series of articles with scientific discoveries made with data Philae has been sending Rosetta from the European Space Agency which broke away to land on 12 November in comet 67P ( 67P / Churyumov-Gerasimenko).

In a study that appears published in the journal Science, the researchers explain that the Cometary Sampling and Composition (COSAC), one of the main instruments of Philae module, determined the existence of organic material in the comet.

Just 25 minutes after landing on the comet, the mass spectrometer of the COSAC took a measurement mode “sniffing”, similar to chemical detectors airports, which revealed the presence of 16 organic compounds, some with none nitrogen and sulfur, according to the study.

Many of these components were detected in the tail of most comets, but methyl isocyanate, acetone, propanal and acetamide compounds that had not been discovered earlier in other comets were also found.

But most important for astrobiology is that some of the materials found in comet dust are considered precursors to life, as involved in the formation of essential amino acids or nucleic bases.

The researchers stressed that comets preserve the pristine material in our solar system in the form of ice, dust, silicates and solid organic matter, which probably formed in interstellar space even before the solar nebula which then became the solar system appear.

The study of the chemical composition of comets also provides crucial information on this in the early solar system matter, whose study is of great importance from the geological point of view because it provides some of the keys to understanding how his training.

In addition, from the point of view of habitability, can help us understand the origin of water on Earth and other planets like Mars and, from the point of view astrobiology, are fundamental to understanding the origin of life on this planet.

Other studies released today describes the time when the robot Philae held its rugged arrival at the surface of the comet 67P, three rebounds and two landings.

After rebounding in the designated landing area, that turned out to have a layer of about 25 soft and grainy centimeters, the module finally stopped in a remote area of ​​rocky consistency, the edge of a crater and on uneven terrain.

The analysis of the two surfaces different consistencies and provided data on the evolution of comets and could serve to improve the design of new missions to others.

The analysis conducted by scientists from the data sent by Philae through Rosetta probe suggest that the landscape of Comet 67P has formed through erosion.

To get a clearer picture of the interior of the comet, scientists counted with measurements obtained from Philae directing electromagnetic signals through comet nucleus to be received by Rosetta on the opposite side.

These measurements suggest that the comet’s head has a fairly homogeneous composition and its interior is even.

To receive information Philae, the Rosetta probe has flown so far in optimal orbit to establish that communication, but on July 24 went to move over the southern hemisphere of the comet’s sunlit, to switch communication with the observation of Philae 67P / Churyumov-Gerasimenko.

ejections of gas and dust in the comet’s surface prevent Rosetta fly very close to the surface and force the probe is kept at a safe distance of between 170 and 190 km.

20 minutosLa ago NASA discovered a mysterious red marks on the … – Economíahoy.mx

Europa Press – 14:01 – 30/07/2015

NASA has found on the surface of Tethys, a moon of Saturn, mysterious red stains It elongated, as if the land had been the ‘aggression’ of a graffiti. The lines form an arc that is “inexplicable” for scientists.

The discovery was made thanks to the images obtained by the Cassini spacecraft, combining spectral filters clear, green, infrared and ultraviolet. According to experts, the pictures show a red bows of narrow and curved on the surface of the moon lines, and are among the most unusual features of color on the moons of this planet.

Some red bows can be seen faintly in the comments made earlier in the Cassini mission, which has been orbiting Saturn since 2004. But the color images for this observation, April 2015, are the first to show large areas of northern Tethys with this anomaly seen clearly.

This is also because, as the Saturn system moves to the northern hemisphere as a result of summer, the northern latitudes are better illuminated. “That’s why the arches are clearly visible for the first time,” he pointed the head of the mission, Paul Schenk. MYSTERY

The origin of the characteristics and their reddish color is a mystery to scientists from Cassini. The possibilities that are covered include chemical impurities in the ice covering the moon, or the result of the degassing of the interior of Tethys. They may also be associated with other characteristics such as geological fractures.

“The red bows must be geologically young because they are opposed to the characteristics of the oldest events such as impact craters, but do not know their actual age,” he pointed one of the scientists, Paul Helfenstein .

At the moment, researchers are waiting because, if the stain is only a thin veneer color on the frozen ground, its exposure to the space environment on the surface of Tethys could erase scales relatively short time.

The color of the image is not real. It has been artificially enhanced to show the chemical differences of the terrain of the moon of Saturn. In real terms, the tones of Tethys are fairly uniform and marks only be visible to the human eye.

Astronomers are not sure about the composition and origin of those marks. What is clear is that they are geologically much younger than the rest of the surface because, in fact, stained oldest brands, such as craters.

A blue moon will be Friday – FORTUNE

(CNN) – Have you heard the saying “once in a blue moon” Friday ?, you can use it.

A blue moon will be this July 31, as is known to the second time that a full moon is recorded in the same month. The last such event occurred in August 2012.

Each month has a full moon, but since the lunar cycle and timing are not perfectly synchronized, every three years we have a blue moon.

The first record of the term dates back to 1524 and referred to the third full moon in a season, according to the Institute of Astronomy at UNAM. However, the term was reinterpreted in 1946 cuandoun magazine article Sky and Telescope the defined as the second month.

Contrary to its name, the satellite does not acquire that tone.

Have you ever changes tone Moon? Yes, but chances that has been blue is a result of smoke or dust particles in the atmosphere, for example during a volcanic eruption.

An example occurred in 1883, when the Indonesian volcano Krakatoa erupted throwing so much ash into the atmosphere that the moon got a cerulean hue for years, night after night.

After the massive explosion that scientists believe is compared with a 100-megaton nuclear bomb, they caused the volcanic debris vibrant red sunsets and the moon to acquire a blue tint.

The last time the moon was blue was in Edinburgh, Scotland in September 1950.

The astronomer Robert Wilson of the Royal Observatory observed the event and concluded it was because the light satellite was traveling through a patch of clouds that had particles of smoke and ash from forest fires in Alberta, Canada.

These particles crossed the Atlantic and floated over Scotland during the lunar event, creating a rare spectacle, according to the National Oceanic and Atmospheric Administration of the United States.

The Blue Moon will be until January 2018.

Nope . Most blue moons are pale gray and white, Moon like you’ve seen on any other night.

That is a second full moon in a month really does not change its color, as explained on the website of NASA.

However, on rare occasions, moon might turn blue.

Already in 1883, for example, People saw blue moons almost every night after the Indonesian volcano Krakatoa exploded with the force of a 100-megaton nuclear bomb. Ash plumes rose to the top of the atmosphere of the Earth and the Moon … it turned blue!

The people also saw moons blue in 1983 after the eruption of the El Chichon volcano in Mexico.

However, is unusual for two full moons occur in a month , to the point that in the US when they want to indicate that something has happened unusual, they say it is something that only occurs when there is a Blue Moon . We invite you to enjoy the next

Astronomers observe auroras first outside our solar system – the Sun of San Luis

EFE

Madrid, SPAIN .- A group of astronomers discovered for the first time outside our solar system, the existence of auroras, similar to the northern or southern on Earth, in a brown dwarf star and a power phenomenon 10,000 times higher, according to a study published today in the journal Nature.

LSR J1835 + 3259 located 18 light years from Earth is the name where astronomers have discovered brown dwarf star the first dawn view a stellar object beyond the solar system.

The auroras are one of the most beautiful phenomena that can be seen in the Earth’s sky and is caused by the interaction of the planet’s magnetic field with the solar wind, but which has observer status in the star is due to a different process.

This discovery has implications for the study of exoplanets, the study conducted by experts from the universities of Sheffield and Oxford.

Brown dwarfs, also called “failed stars” are difficult to detect and remain difficult to classify, because it has a lot of mass to be planets but too small to shoot inside the thermonuclear reactions that feed the stars.

Dr Stuart Littlefair, University of Sheffield said that these results are further proof that we must think brown dwarfs as “reinforced rather than as failed stars planets”.

“We already knew that brown dwarfs have atmospheres with clouds, as though the planets are made of minerals that form rocks on Earth, but now we know that brown dwarfs also have powerful auroras,” he said.

The international team of researchers looked at J1835 + 3259 LSR from the radio astronomy observatory Karl G. Jansky Very Large Array (VLA) in New Mexico, as well as to the Hel Palomar and Keck telescopes in Hawaii.

Their observations show that cooler stars and brown dwarfs have atmospheres that support external auroral activity, rather than the type of magnetic activity seen in other hottest and most massive stars.

This discovery reveals an important difference between the magnetic activity of stars more massive and registered in brown dwarfs and planets.

“All magnetic activity we have seen in this object can be explained by powerful auroras, “said Gregg Hallinan, California Institute of Technology (Caltech) and director of the study adding that this indicates that the auroral activity replaces the solar corona in brown dwarfs and smaller objects.

The aurora scientists observed seemed driven by a dynamo process little understood and similar to that seen in large planets in the solar system.

“What we have seen in that object appears the same phenomenon that we have observed, for example, on Jupiter, but hundreds of times more powerful, “Hallinan said,” suggesting that it may be possible to detect this type of activity on extrasolar planets, many of which have a mass significantly greater than that of Jupiter. “

Littlefair, meanwhile, said that” sometimes the best of a scientific result is simply discover something exciting and new. “

The northern lights “They are one of the most spectacular and beautiful things that can be seen” and as always wanted to see one and so far has not had the opportunity, Littlefair considered a “irony” have uncovered a much larger and more powerful than those on Earth aurora “many light years away.” EFE / AM
