A Quadrillion Tons of Diamonds Lurk Deep Inside Earth
- Scientists found the astonishing quantity of sparkly gems using seismic waves rippling through Earth to estimate the composition of a particular planetary layer.
- This region holds what's known as cratonic roots—inverted mountains of "cold, stable, stiff mantle that's supporting the continents above them," says Joshua Garber, a postdoctoral researcher at Penn State University.
- In the new study, researchers used seismic data to study different models that simulate the three-dimensional warbling of waves moving through Earth.
- Researchers have long known that a massive amount of carbon swirls beneath Earth's crust as carbon dioxide and carbon-rich minerals such as graphite, calcite, and diamond.
- But it may not be the last word on Earth's diamond stash: “I'm taking the conclusions, personally, with a grain of salt,” says Suzan van der Lee, a seismologist at Northwestern University.
Astronomers Discovered 12 New Moons Around Jupiter. Here's How
- Like, say, a dozen previously unknown moons orbiting Jupiter, the discovery of which was announced Tuesday by the International Astronomical Union.
- They needed time for follow-up observations, to see which of the space rocks moved like moons (i.e. in predictable orbits) and which did not.
- Tuesday's announcement makes it official: Sheppard and his colleagues have discovered 12 new objects orbiting Jupiter, bringing the grand total of known Jovian satellites to 79.
- And the peculiar orbit of one of those satellites, in particular—a small object, no more than half a mile across—could explain how many of Jupiter's other moons came to be.
- It was the faintest of the objects Sheppard's team observed, which makes it not only the palest Jovian moon ever discovered, but likely the smallest, as well.
Clues Point to Occupant of Ancient 'Mystery' Sarcophagus
- The discovery of this 30-ton sealed granite sarcophagus, believed to be some 2,000 years old, is prompting speculation about its occupant across the Internet, as well as some questionable mummy jokes.
- Two weeks since its discovery, the sealed black granite sarcophagus uncovered at an Egyptian construction site—a find that has captured the attention of the Internet and sparked countless mummy jokes about the curse it may unleash—has yet to be opened.
- A worn alabaster head of a man, possibly the coffin's occupant, was found nearby, and the burial site was believed to date from the Ptolemaic period (ca.
- One of the two archaeologists believes that, since Alexandria wasn't even founded until the fourth century B.C., the massive sarcophagus may have been brought to the city empty, from an earlier, dynastic-period site down the Nile—such as Memphis—and then re-used to bury someone in later years.
Police are reportedly cutting too-long dresses off ethnic minority women in the middle of streets in China
- Women have been banned from wearing long skirts and burqas and residents barred from fasting during Ramadan, while hundreds of thousands — and possibly even 1 million— people have been sent to extrajudicial "re-education centers" for infringements like growing a beard, calling a loved one overseas or, in some cases, no apparent reason at all.
- Now images on social media appear to show police stopping women and cutting their long skirts and dresses in the middle of the street, despite some women choosing to wear these for comfort rather than religion.
- Although not all scissor-wielders in the photos are dressed like local police it appears they are all attempting to cut long dresses to sit around the hips.
- Authorities have installed surveillance apps on residents' phones and begun collecting DNA samples, fingerprints, iris scans, and blood types from residents aged between 12 and 65.
In Europe, Melania is the Trump sticking to the script
- If Melania Trump was flustered by her husband's somewhat caustic visit to NATO in Belgium earlier in the week, or the thousands of protesters waiting to parade down the streets of London Friday, beneath a large balloon interpretation of the US President in a baby's diaper, she didn't show it.
- The first lady has become something of an expert at the fine art of keeping her composure while her husband is under fire, this time creating a wake of caustic headlines at NATO meetings -- while Melania Trump spent the day tasting chocolates and listening to a violin concerto with leader spouses in a leafy Brussels suburb.
- Melania Trump displayed similar composure during her meeting with Queen Elizabeth II Friday afternoon at Windsor Castle, where she and the President had been invited for tea.
Kapwing is Adobe for the meme generation
- This scrappy new startup is building the vertical video era’s creative suite full of editing tools for every occasion.
- Kapwing hopes to rapidly adapt to shifting memescape and its fragmented media formats, seizing on opportunities like creators needing to turn their long-form landscape videos vertical for Instagram’s recently launched IGTV.
- While sites like Imgur and Imgflip offer lightweight tools for static memes and GIFs, “the tools and community for doing that for video are kinda inaccessible,” says co-founder and CEO Julia Enthoven.
- After starting with a meme editor for slapping text above and below images, Kapwing saw a sudden growth spurt as creators raced to convert landscape videos for vertical IGTV.
- That business model is always in danger of encroachment from free tools, though, so Kapwing hopes to also become a place to view the meme content it exports.
The Digest: VR Treatment, Even Without a Therapist, Helps People Overcome Fear of Heights
- All of the participants in the study filled out questionnaires about the severity of their fear of heights at the beginning of the trial, two weeks later (at the end of the VR treatment program), and again two weeks after that.
- By the end of the trial, 34 of the 49 volunteers in the treatment group expressed a fear of heights milder than the researchers required for them to participate in the study.
- As the study’s lead author, Daniel Freeman, noted in a press release, this could increase the number of people who receive the psychological treatment they need, and not just to address a fear of heights — the researchers plan to see if their automated, VR-powered approach to treatment can work for other mental health disorders, too.
Bear Grylls convinced Roger Federer to climb the Swiss Alps and eat fish eyeballs — and he said it was scarier than playing a Grand Slam final
- In an interview last week on BBC Radio 2, Grylls said how he had tried to convince Federer to come on the show for a long time, and how it was a unique episode.
- It was first to 11, and Grylls got in the lead at seven-love.
- Federer also told Grylls he was way out of his comfort zone, and was a "real scaredy cat" when faced with the climb.
- He added that it just shows, whoever you are, we're all human and we all have fears.
Trump says he and Putin will end up with 'extraordinary relationship' as meeting begins in Finland
- Trump has insisted the two leaders meet at the beginning of the summit without any aides present — stirring concerns that Putin, a former KGB officer, will outflank his American counterpart.
- Monday's highly anticipated meeting takes place in the wake of a contentious NATO summit, and only days after the U.S. Justice Department charged 12 Russian intelligence officers with hacking Democrats in an attempt to interfere with the 2016 election.
- In an interview with CBS that aired on Sunday, Trump said he would "certainly" ask the Russians in Helsinki about the hacking before pivoting to the role his predecessor may have had in the matter.
- Trump said he had not considered asking Putin for the extradition of the indicted agents to the U.S. to face the charges against them.
Russia's Vladimir Putin wins simply by sitting down with President Donald Trump
- He arrived in Helsinki after presiding over the final game of the World Cup soccer tournament in Moscow on Sunday, and was to meet a US president who has spent the last week berating his NATO allies and undercutting his host in Britain, Prime Minister Theresa May. Even the indictment announced on Friday in Washington against 12 Russian military intelligence officers could help Mr Putin by playing into a conspiracy theory long embraced by both the Kremlin and the White House, that the "deep state" is determined to sabotage Mr Trump's outreach to Russia.
- Mr Trump's persistent tirades on the expense of NATO and his fury at the trade practices of the EU, which he recently described as "possibly as bad as China, just smaller", have startled even Russian pundits who have for years watched as Mr Putin, like Soviet-era leaders before him, tried in vain to undermine the trans-Atlantic alliance.
