Google Earth turned 10 years old and celebrates with new features – Los Andes (Argentina)

Google Earth is 10 years old and celebrates by providing users with two new features. Traveller and Earth View

 Since its inception a decade ago, the service that allows to know the world through the web, has advanced image quality and differentiation servicios.Viajero is a function-for the moment only to computers-indicating destinations and color difference according its popularity. Also, it offers pictures and historical reviews that guide searches. For a better view you can get pictures of cities and towns in 3D.

Meanwhile, Earth View is a gallery that collects the best photos taken by satellites. Images can be downloaded at no cost and use it as wallpaper. “On the tenth birthday, we expanded the collection of Earth View 1500 landscapes from all continents and oceans,” said the official blog engineering director of Google Earth, Sean Askay.

10 years , Google executives sought to make the Earth a much more connected to those who take the time to explore, discover and share what they learn (or just for those who have been wanting to see from space the roof of their houses) instead. And they did it when they created Google Earth. Million users, compared to the screen of their devices, have access to the most remote places on Earth with high definition photos captured by satellite.

The trivial facet of Google Earth turned towards the social aftermath of Hurricane Katrina, then he demonstrated the usefulness of mapping.

The rainbow of Facebook not enough, according to the LGBT community – FORTUNE

Facebook was filled this week painted with the colors of aicoíris as a way to celebrate the legalization of gay marriage across America photographs, however, part of the LGBTQ community considers the social network not supported since their policies impede the use of pseudonyms.

Among the participants of the Gay Pride parade in San Francisco last weekend, were about 70 members #MyNameIs, a coalition of LGBTQ people with signs in which “shame read, Facebook “and” #MyNameIs “( my name is ) to protest against the policy of real names, they consider discriminates against community members.

The group had asked Facebook to refrain from participating in the parade, but organizers voted to allow it.

“Facebook is proud of our commitment to diversity and our support for the LGBTQ community as a company and as an employer,” said a spokesman for Facebook. “We have been strong supporters of the parade of San Francisco for many years.”

However, people who were expelled from the site by the names they chose for themselves known remain unconvinced.

A slow change

Users of Facebook can bring people to use false names. After complaints had the LGBTQ communities and others who want to protect their identity, Facebook changed its policy.

Instead of real names, Facebook now asks users to give their “true identity”.

Since then, Facebook has restored thousands of accounts were blocked and people belonging to the network using names other than his legal name.

“But that was just a Band-Aid,” he said Lil Miss Hot Mess a drag queen whose account was temporarily blocked in September 2014 as reported he used a false name. “The more people we helped, the more he was injured to the cause in general. It seemed that Facebook wanted to handle things case by case basis rather than changing the policies.”

Facebook expanded options accepted identifications and credentials now includes libraries, mail subscriptions and magazines, among others.

“But I do not have a library card with the name Little Miss Hot Mess” said drag queen of San Francisco. “In addition, they ask that the identification has birthdate and photography; a library card has never photo, not the mail.”

Identity Crisis

Other participants of the protest #MyNameIs say that Facebook refuses to accept people who question their identity.

Dotie Lux, lesbian, producer and cabaret artist, said that people of the LGBTQ community may have a different name because of the lack of support from family and friends.

“For me it was really important tune my own identity and find out who I am,” he says. “Facebook has told me I do not exist but for the people who gave me life.”

Zip, an employee transgender Facebook that initiated the much celebrated genre depending on the extent to Facebook, was blocked on Sunday June 28.

“I chose my name Facebook six years ago and started my transition. All the people I’ve met since then generally know me by that name and that is in part precisely to use it in Facebook” Zip, who is named in the credential used on the website Medium she said.

Facebook needs to allow marginalized communities have access to friends and support without having to take a forced name, said Zip.

Real names, real dangers

Facebook noted that identity verification is intended to determine responsibilities, prevent fraud and reduce the harm and harassment that They take refuge in anonymity.

However, the policy also prevents people hide their identity, resulting in a safety.

“We’ve known women who contact the former aggressors or stalkers, gay and transgender people have feared losing their jobs,” said Trisha Fogelman, advocate for victims of domestic violence, in the statement that #MyNameIs published Sunday.

Facebook takes action based on the comments received, but refuses to completely eliminate its policy because its policy of authenticity is what sets them apart from other social networks.

As an actor you may prove what is your true identity. But for members of the LGBTQ community who have not disclosed their real situation for survivors of violence and to others who want to use pseudonyms that can not be easily verified, the limit becomes more diffuse.

USA, 30 / 06/2015 (The People’s Daily Online) – This Tuesday, June 30 is the longest day of the year 2015 due to the slowdown of the motion of the planet, however, only be a second time.

“The Earth’s rotation is gradually slowing down and called leap seconds are used to adjust,” says Daniel MacMillan, Center Goddard Space Flight NASA.

The Earth . gradually slows down due to a braking force caused by the gravitational struggle between the Earth, Moon and Sun

So this 30 June to reach 23:59:59, the clock will strike 23: 59:60 00:00:00 before giving.

According to experts the world since 1972 has won 15 seconds due to these changes.

Today is the longest day of the year. – Efe

Madrid <- - end pub!> |

The next June 30 will have a second to compensate for slight variations in the duration of day that they accumulate and produce a lag between the time when the clocks and the rotation period of the Earth are based.

This was decided by the International Earth Rotation Service, based in Paris in a bulletin released earlier this year, Francisco Colomer, the National Astronomical Observatory (NAO) said.

In particular, Colomer explained, the last minute of June 30 will have 61 seconds.

The need of inserting an extra second is that tiny variations in day length accumulate because the Earth is not a rigid body, its rotation is affected by the coupling of core liquid mantle, oceans, atmosphere.

These accumulations produce a gap between the Coordinated Universal Time, which is the atomic time when it comes to our watches is based, and time bound to the Earth’s rotation, which draws on the Sun’s position, explained

The invention of atomic clocks measure time allowed for more accurate and in 1970 an international agreement recognized the existence of the two timescales:. the planet’s rotation period and the so-called Coordinated Universal Time or UTC. Service International Earth Rotation and Reference Systems Jump is the organization that looks at the difference between the two scales and notes must be inserted or removed when one second of UTC.

NASA explains why tomorrow, Tuesday, the day will have a second … – Economy and Business online

On Tuesday the day is imperceptibly longer than usual, as it will add one second.

“The Earth’s rotation is slowing somewhat gradually, so this extra second realizes that, “said Daniel MacMillan, the Goddard Space Flight Center in Greenbelt, Maryland. A day lasts exactly 86,400 seconds.

However, the average solar day is what it takes for the Earth to make one complete rotation is about 86400.002 seconds. This is because this rotation is slowing gradually, due to forces that slow as the gravitational pull between the Earth, Moon and Sun. Scientists estimate that the last time that day lasted exactly 86.4 thousand seconds was about 1820.

This difference of two milliseconds, much less a note not blinked. But when it is repeated daily for a year it becomes almost a second.

The day length is influenced by several factors, notably atmospheric type as those produced by El Niño. Other factors contributing to this are groundwater and ice.

Scientists monitor what it takes Earth to complete rotation using an extremely precise technique called “Very Long Baseline Interferometry”. These measurements are made through a network of global stations, which are coordinated by Goddard, which also analyzed and the data are archived.

With this information, you decide to add a second when necessary, determination making the Service and Reference Systems International Earth Rotation. The second to be added is not something you can predict a long time, so it was elegico insert the June 30 or December 31.

Private space capsule “Dragon” Sunday exploded a few minutes later taking off from Cape Canaveral, Florida, bound for the International Space Station (ISS). “Missed something at launch,” wrote the US space agency NASA on Twitter.

The unmanned spacecraft was destroyed. appeared “irregularity” to be investigated, wrote the responsible firm SpaceX on Twitter without elaborating. For this afternoon, NASA announced a press conference.

The explosion is a blow to NASA and SpaceX. The “Dragon” was carrying 2,000 kilograms of supplies and scientists to the three astronauts currently stationed at the ISS equipment. It was the seventh supply freighter flight to the station. On previous trips there were minor problems but always the mission was accomplished.

In late October the “Cygnus”, another ferry unmanned developed by Orbital signature Sciences, also exploded during takeoff to the ISS.

The ISS received supplies last April through the capsule “Dragon”. NASA did not say so far whether this represents a problem for the supply of astronauts. In general, the ISS is usually stocked with several emergency rations. “I watched the launch from space,” wrote the American astronaut Scott Kelly from the ISS. “Sadly went wrong. The work in space is difficult.”

An employee of the Russian space navigation would not give his name spoke of a serious loss. On board were spacesuits for US astronauts and important tools, the Russian news agency Interfax reported.

(Technology) EDITION WATCH THE APPLE IS A BAD … – Terra Mexico

(TECH) THE APPLE EDITION WATCH IS A BAD INVESTMENT

MEXICO, Infosel June. 26. From this Friday it will begin marketing the Apple Watch in Mexico, the smart watch with Californians made a couple of months his triumphant debut at the wearable technology market. Business is so good for the company founded by Steve Jobs, that since Apple Watch was released excess orders caused the device to acquire customers have to wait even a few weeks to get it.

The cheapest model costs six thousand 799 dollars and the most expensive 315 000 pesos. By price, the first costs (Liverpool) more than a watch Nivada Moonmaster and second short of Girard Perregaux 1966, both pieces of fine Swiss machinery. Notably between fine watches machinery notable differences hence the gap between their prices; however when it comes to cheaper wearable signature and gold edition there are no technical differences so your machine is exactly the same.

But the smart luxury watches do not compete with much less fine watches and pieces of fine watchmaking, because their natural obsolescence implies a subsequent devaluation and consequently a bad investment. The example they put cell phones, like the Nokia 6700 classic Gold Edition and 88 Tauri Lamborghini Mobile.

The Finnish was announced in late 2009; its starting price was about $ 400 and two years later the team and was quoted at $ 150 per internet. Its technical characteristics are now practically obsolete; contemporary reference is iPhone 3GS. The Galaxy S range was not yet submitted.

The Lamborghini model was launched in late 2014 with a starting price of six thousand dollars; despite their technical specifications are much weaker than those that integrated the Google Nexus 5 of leaving an estimated cost was $ 520. The website The Verge compared to a “supercar” is nothing but car accelerates from 0 to 60 mph in five seconds.

On the smartwatches, some other companies besides Apple have chosen to manufacture luxury technological devices, such as HP and designer Michael Bastian and more recently Google, which announced a partnership with the Swiss company TAG Heuer watches with which also plans to launch a luxury SmartWatch. Switzerland has always been known for its watch industry, it is one of the best in the world and supplies 50% of world production of watches; however with the arrival of the SmartWatch it was thought that this would mean a major setback for the Swiss industry, however the same watchmakers ensure that devices like Apple Watch pose no competition.

An example is opined by Guy Semon, director of brand Tag Heuer, who said that “Apple Watch is not really a watch” while challenging assured that “all Swiss watches are smart” this part of the world’s largest exhibition of watchmaking in the Swiss city of Basel Baselworld.

In an interview Infosel, Jose Alberto Garcia, a watch collector with over 20 years experience in this activity, said a traditional clock is a personal item that defines and identifies the male figure, what specifically Watch Golden Apple is far from the features that an expert looking for.

He also added that the wearable “lacks personality, is androgynous and delicate, is beautiful and fine, but ignores 100 years of struggle against the elements of the wristwatch” also confronted the behavior of the device spaces won by the Swiss watch and clock analogy compares with a “beautiful girlfriend who can not bare that gives cold”.

Garcia says the Apple Watch does not comply with the features that a collector looking at a clock fine machinery as the first base of collecting is the value of an investment over which the wearable gold Apple is just “added value”.

He also added that the SmartWatch giant’s Cupertino right now is a coveted and expensive item, but when they pass their peak “will have more pieces on the market that collectors willing to pay for what will go down (much) the price, while a clock is re-assessed after 30 years and 50 reaches its best “.

Corals mutate their DNA to adapt to climate change: … – LaRed21

Evolution

hours

Australian and American scientists, who work at the University of Texas, have found that the corals of this variety are transmitting heat tolerance in their DNA, which is allowing them to survive more amount, in the warmer waters of the oceans where his predecessors enjoyed more moderate temperatures.

The corals are particularly sensitive to temperature changes in the sea surface, and kills whitening colonies , but some survive better than others, although all come from the same latitudes where they were living for millions of years, until changes induced by man, altered their habitats.

The crossing of species could save coral

The last study published in the journal Science, crossed corals of the same variety, but from two niches with five degrees of latitude difference: Princess Charlotte Bay and Orpheus Island, both in the Great Barrier Reef of Australia, but with more than 2 degrees apart. Coral larvae born, were exposed to increasingly warm temperatures and turns to cross. The genes of individuals who were born in the new generations, had a 10 times greater resistance to exposure to heat, than the originals.

The work, “suggests that resistance to temperature corals which varies depending on the latitude, it is passed from generation to generation and remote coral populations are not simply acclimatize to their different environments, “explains Sync agency that collects the report.

The news opens a promising field in the world of corals, whose extinction has been anticipated by scientists in the context of increasing climate change and its impact on the oceans.

Some corals and adapt to global warming – Time Patagonico

Coral reefs are threatened worldwide by increasing the temperature of the sea surface, which causes its whitening and therefore his death in the absence of food. However, some species of coral have greater resistance to high temperatures, but so far no known reason.

American and Australian researchers led by the University of Texas at Austin (USA), now reveal that some populations of corals already have genetic variants that allow them to tolerate the warm waters of the oceans. To demonstrate this, the team crossed Acroporamillepora corals originating in the Australian Great Barrier Reef, specifically two places with a difference of five degrees of latitude between them: Princess Charlotte Bay and the island Orpheus.

In the study, published this week in Science, scientists exposed for long periods of coral larvae to increasingly warm temperatures, and then analyzed the genes of individuals who survived. The results show that the cálidas- more heat-tolerant corals Princess Charlotte Bay-at northern Australia, with water 2 ° C produced larvae that were 10 times more likely to survive exposure to heat larvae corals Orpheus Island -more south and less resistentes-. The researchers were thus able to identify differences in gene expression of corals, which appeared to be related to hereditaria- and heat resistance. The work suggests that corals resistance to temperature, which varies depending on the latitude, transmitted from generation to generation and remote coral populations is not simply acclimatize to their different environments.

Swap corals to save

“Corals do not have to wait for new mutations to appear. So to prevent the extinction of corals could exchange some populations and extend its existing genetic variant “said Mikhail Matz, a scientist at the University of Texas. The team showed that if corals Princess Charlotte Bay intersect with corals Orpheus Island can transmit heat resistance to their offspring.” Although coral larvae can move naturally from oceans, humans can also help relocate corals adults and restart the process, “says Matz.

” This finding allows us to better understand the potential of corals to overcome increased ocean temperature, “he concludes Line Bay, co-author and researcher at the Australian Institute of Marine Science (Australia)
