Washington, Dec 18, 2016: Scientists have claimed to figured out how the world’s biggest and most-valuable diamonds formed, media reported on Sunday.

In a study published this week in the US journal Science, the scientists said large gem-quality diamonds, like the world-famous Cullinan or Lesotho Promise, may be born in metallic liquid deep inside the Earth’s mantle, Xinhua news agency reported.

The research team, led by Evan Smith of the Gemological Institute of America, reached the conclusion after examining so-called “offcuts” of massive diamonds, which are the pieces left over after the gem’s facets are cut for maximum sparkle.

They found tiny metallic grains trapped inside in more than 30 exceptionally large stones, which are made up of a mixture of metallic iron and nickel, along with carbon, sulfur, methane, and hydrogen.

These inclusions led the researchers to conclude that these diamonds formed, like all diamonds, in the Earth’s mantle, but they did so under conditions in which they were saturated by liquid metal.

Most diamonds formed at depths of 150 to 200 km under the continents and shoot to the surface in volcanic eruptions.

“Pure carbon crystallised in this mix of molten metallic liquid in Earth’s deep mantle to form diamonds,” the team explained in a statement.

“Small droplets of this metallic liquid were occasionally trapped within the diamonds as they grew,” offering useful clues that may help “advance our understanding of Earth’s deep mantle, hidden beneath tectonic plates and largely inaccessible for scientific observation,” the statement added.

The findings may tell scientists about oxygen availability in different parts of the mantle.

Near the surface, the mantle chemistry is more oxidized, which scientists can tell from the presence of carbon in the form of carbon dioxide in magmas erupted in volcanoes.

“Previous experiments and theory predicted for many years that parts of the deep mantle below about 250 km depth contain small amounts of metallic iron and have limited available oxygen,” Smith said. (IANS)

Aadhaar Helpline Mystery: French Security Expert Tweets of doing a Full Disclosure Tomorrow about Code of the Google SetUP Wizard App

Google’s admission that it had in 2014 inadvertently coded the 112 distress number and the UIDAI helpline number into its setup wizard for Android devices triggered another controversy on Saturday as India’s telecom regulator had only recommended the use of 112 as an emergency number in April 2015.

After a large section of smartphone users in India saw a toll-free helpline number of UIDAI saved in their phone-books by default, Google issued a statement, saying its “internal review revealed that in 2014, the then UIDAI helpline number and the 112 distress helpline number were inadvertently coded into the SetUp wizard of the Android release given to OEMs for use in India and has remained there since”.

However, the Telecom Regulatory Authority of India (TRAI) recommended only in April 2015 that the number 112 be adopted as the single emergency number for the country.

According to Google, “since the numbers get listed on a user’s contact list, these get  transferred accordingly to the contacts on any new device”.

Google was yet to comment on the new development.

Meanwhile, French security expert that goes by the name of Elliot Alderson and has been at the core of the entire Aadhaar controversy, tweeted on Saturday: “I just found something interesting. I will probably do full disclosure tomorrow”.

“I’m digging into the code of the @Google SetupWizard app and I found that”.

“As far as I can see this object is not used in the current code, so there is no implications. This is just a poor coding practice in term of security,” he further tweeted.

On Friday, both the Unique Identification Authority of India (UIDAI) as well as the telecom operators washed their hand of the issue.

While the telecom industry denied any role in the strange incident, the UIDAI said that he strange incident, the UIDAI said that some vested interests were trying to create “unwarranted confusion” in the public and clarified that it had not asked any manufacturer or telecom service provider to provide any such facility.

Twitter was abuzz with the new development after a huge uproar due to Telecom Regulatory Authority of India (TRAI) Chairman R.S. Sharma’s open Aadhaar challenge to critics and hackers.

Ethical hackers exposed at least 14 personal details of the TRAI Chairman, including mobile numbers, home address, date of birth, PAN number and voter ID among others. (IANS)
