Crystal confirmed as oldest known piece of Earth

On a sheep farm in Australia, scientists from the University of Wisconsin have found what they believe is the oldest piece of Earth ever discovered. 

"Here it is, a zircon crystal 4.4 billion years old. That's almost as old as the earth itself which is thought to be 4.5 billion years old." (Via CBS)

The crystals are thought to have formed just millions of years after our planet was only a ball of molten rock — much too hot to support life or even land masses. (Via History Channel

The study's lead researcher, professor John Valley, said in a statement, "This confirms our view of how the Earth cooled and became habitable. This may also help us understand how other habitable planets would form.” (Via University of Wisconsin)

The zircon crystals are so tiny, if you were holding one in the palm of your hand you wouldn't even know it without a microscope. They come in all different shapes and can be completely transparent all the way to a deep red color. 

The sheep farm in Australia, called Jack Hills where the crystals were found, was actually a beach about 3 billion years ago, researchers say. The scientists say even then the crystals were merely a speck of sand. (Via NASA)

Now, the position of the atoms in the crystals is how the researchers determined their age, but some critics say it's possible those atoms could have shifted — making the crystal appear older than they actually are. But the study's lead researcher explained to NPR his team was able to confirm the age using an instrument that can extract atoms from the crystals. 

A geologist at the Massachusetts Institute of Technology backed up the method, "I think people will be impressed with the technique and impressed with the conclusions and agree with them. Now we're talking about a history on this planet that goes back to almost the day that the planet was born."

Valley's team is now using that technique to look at zircons from the moon brought back from the Apollo astronauts. The hope is one day they will stumble over a larger form of a zircon that dates back just as far, if not farther than the new findings.

  • A pair of escalator mechanics have been arrested after police say they tampered with an escalator in the Langham Place mall in the Mong Kok area of Hong Kong, causing a dangerous situation. They were questioned after an incident in which the escalator abruptly changed directions, sending passengers plummeting to the ground floor of the mall. Eighteen were injured; one man was hospitalized in serious condition for a head wound. >> Read more trending news In a statement obtained by CNN, Otis Elevator Co. spokesperson Ian Fok called the arrest of its employees “a surprise.” He added, “Our legal team is working with law enforcement to clarify the situation and intends to defend our mechanics.” Video obtained by the South China Morning Post shows the moment the escalator changed directions, eliciting screams from dozens of people riding at the time.
  • A Canadian man will have to come up with a new vanity license plate, or decide to go with the standard tag, after he was told his plate could be misinterpreted. >> Read more trending news  Lorne Grabher has had his last name on his license plate for decades, but a few months ago received a letter from the Nova Scotia Registry of Motor Vehicles has canceled the plate after 25 years, CBC reported. That’s because others “can misinterpret it as a socially unacceptable slogan.” Grabher is now calling out Nova Scotia officials for discrimination. The Department of Transportation told the CBC via email that they received a complaint over the plate “as misogynistic and promoting violence against woman” and that they cannot mark that it is a name vs. an action. Nova Scotia has made about 3,100 words not acceptable for license plates including HESHE and GOD4U2.
  • The family of an American slain in last week's attack in London expressed gratitude Monday for the kindness of strangers as they insisted some good would come from the tragedy. Kurt W. Cochran from Utah was on the last day of a European trip celebrating his 25th wedding anniversary when he was killed when an attacker mowed down pedestrians on Westminster Bridge before stabbing a police officer in a Parliament courtyard. Cochran's wife, Melissa, suffered a broken leg and rib and a cut head, but is steadily improving. 'So many people have been so kind, and we are deeply touched by their goodness and generosity,' said Melissa Cochran's brother, Clint Payne. 'Your notes, prayers, donations and love have helped us so much.' Attacker Khalid Masood was shot dead by police after his deadly rampage, which police have revealed lasted just 82 seconds. Police believe Masood - a 52-year-old Briton with convictions for violence who had spent several years in Saudi Arabia - acted alone, but are trying to determine whether others helped inspire or direct his actions. Detectives on Monday continued to question a 30-year-old man arrested Sunday and a 58-year-old man arrested shortly after Wednesday's attack. Both were detained in the central England city of Birmingham, where Masood had recently lived. Meanwhile, the British government repeated calls for tech companies to give police and intelligence services access to encrypted messages exchanged by terrorism suspects.

  • Three days after a GOP health care bill melted down in the U.S. House before a vote, the White House said President Trump is not giving up on his desire to overhaul the Obama health law, as Republicans in the Congress also urged the President to keep pushing ahead on major health insurance changes. “I don’t think it’s dead,” said White House Press Secretary Sean Spicer said of the failed GOP health bill, which foundered even after repeated efforts by the President to twist the arms of reluctant Republican lawmakers. “We’re at the beginning of a process. I don’t think we’ve seen the end of health care,” Spicer added, labeling the Obama health law, “an abysmal failure.” Spicer said the White House is currently going through a post-mortem on what went right and what wrong in their effort, as he said members of both parties in Congress had already reached out to both the White House and Mr. Trump about finding some common ground on health care policy. Spicer: Trump has received calls from Republicans and Democrats offering to work with him to improve health care https://t.co/ZQHMnWGI3O — CNN Politics (@CNNPolitics) March 27, 2017 On Capitol Hill, both parties were still sifting through the embers of the GOP health care bill, which was yanked off the House floor on Friday afternoon before a final vote, clearly short on support, as it divided Republicans along several fault lines. For many GOP lawmakers, the idea of giving up after just 18 days of work on health care changes, was not an option. “We cannot walk away now, without even a vote,” said Rep. Luke Messer (R-IN), a junior member of the House GOP leadership, said on the House floor. “I will continue to fight for a conservative bill to repeal Obamacare and rebuild a people-first health care system,” said Rep. Richard Hudson (R-NC). But there was no immediate signal on whether the White House or GOP leaders in Congress would look to tinker with the failed health bill of last week, or maybe start to develop a new plan.
