There may be an ancient Earth inside the Earth

A team of scientists at Harvard University believes they have found evidence that there is an ancient Earth within our planet. The team believes that a previously unexplained isotopic relationship from deep within the Earth could be a signal of the material before our world collided with another body the size of a planet, which led to the creation of the Moon. This could be an echo of an ancient Earth that existed 4,500 million years ago, before the proposed collision.

The current favored theory says that the Moon was formed 4.5 billion years ago when the Earth collided with a mass the size of Mars, nicknamed “Theia”. This theory states that the heat generated by the collision would have melted the entire planet before some of the debris splintered to create the Moon.

But now, the Harvard team, led by Associate Professor Sujoy Mukhopadhyay, believes they have found evidence that only part of the Earth melted and that an old part still exists within the mantle of the planet.

According to Professor Mukhopadhyay: “The energy released by the impact between Earth and Theia would have been enormous, certainly enough to melt the entire planet. But we believe that the impact energy was not distributed evenly throughout the ancient Earth. This means that a large part of the impacted hemisphere would probably have vaporized completely, but the opposite hemisphere would have been partially protected, and would not have completely melted. ”

The team analyzed the proportions of noble gas isotopes from deep within the Earth’s mantle and compared the results with the isotope ratios closest to the surface. They found that the ratio of 3He to 22Ne from the shallow mantle is significantly higher than the equivalent ratio within the mantle.

Professor Mukhopadhyay commented: “This implies that the last giant impact did not completely mix the mantle and there was not an entire ocean mantle of magma.”

More evidence comes from the analysis of the relationship of 129-Xenon to 120-Xenon. The material that reaches the surface from the deep mantle has a lower proportion than is normally found near the surface. Because 129-xenon is produced by the radioactive decay of 129-iodine, the isotopes locate the age of formation of the ancient mantle section within the first 100 million years of Earth’s history.

“The geochemistry indicates that there are differences between the isotope ratios of noble gases in different parts of the planet, and these must be explained. The idea that a very disruptive collision of the Earth with another body the size of a planet, the largest event in the geological history of our planet, was not completely fused and homogenized, challenges some of our notions about the formation of planets and the energy of giant impacts. “If the theory is correct, we may be seeing echoes of the ancient Earth, from a moment before the collision,” said Professor Mukhopadhyay.

Researchers exploit the system that sends presidential emergency alerts

Researchers discovered a manner to exploit the system that sends presidential emergency alerts to our phones, simulating their method on a 50,000 seat football stadium in Colorado with a ninety percentage achievement charge.

Researchers at the university of Colorado Boulder posted a paper this month that details how they were capable of spoof assault the wi-fi Emergency Alert (WEA) software, which could ship out AMBER indicators, presidential signals, and each extreme and severe threats to safety.

Emergency alerts are sent to every cell tool within variety of the broadcasting mobile tower. but the researchers word that a malicious cell tower channel is capable of fooling the device, and in turn sending out an inauthentic emergency alert to all gadgets within its variety.

The researchers tested this LTE vulnerability by using developing their very own malicious cellular tower channel using off-the-shelf hardware and open-supply software to deploy their exploit, which in one instance become used in an test at Folsom subject on the college of Colorado Boulder.

The researchers didn’t perform an actual assault on a live crowd on the stadium or on real cell gadgets, Eric Wustrow, a researcher on the paper, instructed Gizmodo in an e mail. The assessments performed have been rather accomplished in remoted RF protect bins, Wustrow stated, “and our analysis of Folsom area changed into a aggregate of empirically collected data and simulation.” A screenshot from the paper beneath displays what those spoof attacks looked like on both a Samsung Galaxy S8 and an iPhone X.

North Korea Published a Letter From “Abraham Lincoln” to Obama

It’s common for the North to throw operatic insults at the military and diplomatic skill of both South Korea and the US. In April 2016, they went one step further, conjuring a letter from deceased 16th president Abraham Lincoln to President Obama. The “Lincoln letter – “dvice from Lincoln to Obama” was published on the internal state-run website DPRK Today, and was titled “Advice from Lincoln to Obama.”

Concern trolling Obama by saying that it looks like he has “a lot on his mind,” the letter scolds him and the US for not reducing their nuclear weapons stockpile, while simultaneously demanding the DPRK reduce theirs. “Lincoln” even throws himself under the bus, saying the American people won’t stand to be deceived the way he did back in the day.

“Hi there, Obama,” begins the letter in a guess-who’s-back-motherfucker kind of way. “I understand how perplexed you must feel nowadays, but I think this is the time for you to gather your thoughts as a president of a nation.”

In the letter, Lincoln derides Obama’s Nobel Peace Prize-winning push to build a nuclear-free world by questioning why the United States has not taken the initiative to scale back its nuclear arsenal first, even as it asks countries such as North Korea to scrap their atomic programs.

“If the United States, a country with the world’s largest nuclear weapons stockpile, only pays lip service, like a parrot, and doesn’t do anything actively, it will be a mockery to the entire world,” the letter has Lincoln say.

Although the fake Lincoln criticizes Obama, the North doesn’t portray the late president as a good leader.

Student briefly become the owner of Google.com domain

It happened a few years ago! Google forgot to renew and the name was snapped up by a student who paid $12.00 for it. He initially thought the listing was an error, but was surprised when his payment went through and he got a confirmation email saying he was now the owner of the world’s most-visited domain.

He owned it for a minute, and the reports say that he ‘even had access to the inner workings of the site’ though I don’t how that can be possible.

He actually bought it through Google domains who had listed it as available, and received an email congratulating him on now owning the worlds most visited domain! Google apparently paid him a fee that looks like Google 6006.13, but when they learned he was donating it to charity, they doubled it!

Google regularly gives financial rewards to computer researchers who alert them to bugs or errors in their services – in the blog post, they revealed that they paid out over $2 million (£1.4 million) to more than 300 security tipsters in 2015 alone.

Researcher Tomasz Bojarski was the most prolific bug-finder of 2015, spotting 70 bugs in Google throughout the year. One of these bugs, ironically, was found in the web form where users can report security flaws.
