Earth may be known as the Blue Planet now, but evidence suggests that back in the day, it was probably pink.

Scientists have discovered the earliest evidence for a color appearing in nature: "bright pink pigments" that exist in an ancient kind of chlorophyll, said Dr. Nur Gueneli, a researcher with the Australian National University. Discovered inside rocks found under the Sahara Desert in West Africa, these pigments are believed to be over 1.1 billion years old, Interesting Engineering reported.

While the chlorophyll we learn about in science classes today is green, this prehistoric version was used by marine bacteria that cast a "brilliant pink" color over the ocean all those years ago, Live Science explained. That hue wouldn't be overtaken by greener algae for hundreds of millions of years.

That algae eventually turned into the basis for the wide variety of life that led to the evolution of large animals, including humans. But a billion years ago, "the planet belonged to the bacteria," Live Science reported.

CNN just won a major victory in its lawsuit against President Trump. A judge said on Friday that the White House must restore CNN reporter Jim Acosta's press pass.

Judge Timothy J. Kelly, who was appointed by Trump, said that the White House did not provide Acosta with due process when it suspended his press pass last week, per CNN. Trump had done so after a contentious exchange during a press conference, in which Acosta held on to the microphone to ask a follow-up question as an intern tried to take it away. CNN sued members of the Trump administration, arguing that the suspension violated Acosta's First and Fifth Amendment rights.

Kelly did not actually reach a conclusion in the case itself, but he granted CNN's request for a temporary restraining order that will allow Acosta to return to work at the White House. The judge did, however, say that his ruling was limited and suggested the White House could try to revoke the pass again should it provide Acosta with due process, CNN reports.

CNN celebrated the decision on Friday. "We are gratified with this result and we look forward to a full resolution in the coming days," the network said in a statement. The network is also looking to have the judge rule on whether the decision to revoke Acosta's press pass was unconstitutional, and the case could still head to trial, The Washington Post reports. The White House subsequently said that it would "temporarily reinstate" Acosta's pass and "further develop rules and processes to ensure fair and orderly press conferences in the future."

Amazon's HQ2 means up to 25,000 new workers could end up in New York City. It also means there will be nearly 5,000 fewer homes for city's residents.

Queens-based manufacturer Plaxall had developed an in-depth plan to build 4,995 new homes in Long Island City, "1,250 of which developers would have set aside for low- and middle-income New Yorkers," Politico reports. But Amazon's imminent arrival has zapped much of their plans.

On Tuesday, Amazon confirmed it would split its second headquarters between Long Island City, Queens, and Crystal City, Virginia. New York City Mayor Bill De Blasio discussed the plan in a press conference later that day, saying that putting "one of the biggest companies on earth next to the biggest public housing development in the United States — the synergy is going to be extraordinary." The mayor promised to create 300,000 affordable apartments by 2026.

But the massive Amazon deal doesn't exactly match up with De Blasio's words. Plaxall will be left with just two of the 14.7 acres it originally slated for housing, and the company might just turn those leftovers into office space, Politico says. Another developer will lose space it set aside for 1,000 new units, including 250 that would've been designated as affordable.

Queensbridge public housing residents have mixed feelings about their new neighbors, especially since "the deal does not require Amazon give preferential hiring treatment" to public housing tenants, writes the New York Post. The deal will also cost New York $1.525 billion in tax incentives, leading Long Island City's state Sen. Michael Gianaris to tell Politico "the more we learn about this deal, the worse it gets."

Education Secretary Betsy DeVos is still receiving constant protection from the taxpayer-funded U.S. Marshals Service, and the security detail is now expected to cost nearly $20 million through September 2019, NBC News reported Friday.

DeVos has received this around-the-clock protection since being confirmed in February 2017, as was previously reported, with former Attorney General Jeff Sessions granting the request. This arrangement is unusual, NBC News writes, because an education secretary’s security would typically be handled by the department's internal enforcement, and DeVos is the only current member of the cabinet who has such a detail arranged.

In terms of the price tag, the report notes that former EPA Administrator Scott Pruitt's security cost $3.5 million during his first year in office, and the EPA's inspector general found that price tag to be "not justified." DeVos' security, on the other hand, is estimated to cost taxpayers $7.7 million just for the next fiscal year. It will reportedly be reimbursed by the Department of Education.

The request for this detail was made shortly after DeVos was heckled by a group of protesters when she visited a middle school in February 2017. The Justice Department says the order was issued after the Department of Education contacted them about "threats received by the Secretary of Education," although an Education Department spokesperson says DeVos didn't make the request. Since she started receiving her security detail, DeVos has reportedly spent less than four percent of her time visiting public schools. Read more at NBC News. Brendan Morrow

William Goldman, the award-winning screenwriter behind The Princess Bride, Butch Cassidy and the Sundance Kid, and All the President's Men, has died at 87, Deadline and The Washington Post reported Friday.

Goldman died Thursday night at his home in Manhattan, Deadline reports, noting that he had been in ill health and his condition had deteriorated over the summer. No cause of death has been released.

Goldman began his career as a novelist, but he soon transitioned into Hollywood and became best known for his movies — screenwriter C. Robert Cargill on Friday described him as the "patron saint of screenwriting." His first screenplay was the 1969 classic Butch Cassidy and the Sundance Kid, for which he took home an Academy Award. He would go on to win a second Academy Award for writing All the President's Men in 1976, and he also wrote the screenplay for The Princess Bride, which was based on his novel of the same name. Over the course of his career, Goldman produced dozens of screenplays and consistently worked as a script doctor; some of his other movies included The Stepford Wives, Marathon Man, Heat, Misery, and Chaplin.

After winning his second Oscar, Goldman shared his knowledge of the industry in the book Adventures in the Screen Trade, in which he famously declared that in Hollywood, "Nobody knows anything." Brendan Morrow

North Korean leader Kim Jong Un attended an inspection of what state media there is describing as an "ultramodern tactical weapon," The Washington Post reports Friday.

This is the first time North Korea has publicly announced a weapons test since November 2017, CBS News reports, while noting that this does not appear to be a nuclear device or a long-range missile; the country previously said it would suspend its nuclear and missile tests. A military expert told CBS News that a "tactical weapon" in North Korea would refer to a "weapon aimed at striking South Korea, including U.S. military bases." An anonymous South Korean government official told CNN that it's likely a "multiple rocket launcher;" a South Korean-based researcher told CNN it's probably not a missile, though, as South Korea would have detected that.

Since President Trump participated in a summit with Kim Jong Un earlier this year, North Korea has demanded sanctions against them be lifted, and a North Korean Foreign Ministry official recently said Kim could start "building up nuclear forces" if the U.S. doesn't do so, CNN reports. Vice President Mike Pence on Thursday said Trump and Kim will meet again in 2019 even without North Korea providing a list of its nuclear weapons and missile sites, though Pence said it's "imperative" for the U.S. to come away from this second summit with a "plan for dismantling nuclear weapons." North Korea's state media said Friday that Kim was could barely contain his "passionate joy" after the successful weapons test, The Washington Post reports. Brendan Morrow

President Trump last week floated the idea of a "new election" in Arizona. But now, it's Democrat Stacey Abrams who may be pushing for that option in Georgia.

Republican Brian Kemp currently holds an 18,000-vote lead over Abrams in the Georgia gubernatorial election, but with the official state certification of the results possibly coming on Friday, The Associated Press reports that Abrams' campaign is preparing an "unprecedented legal challenge" that could involve pushing for a new vote.

Abrams would be challenging the result by saying there was "misconduct, fraud, or irregularities," enough "to change or place in doubt the results," as outlined in Georgia election law. Her team would then assemble affidavits from voters who say they were disenfranchised. Abrams accused Kemp of voter suppression throughout the campaign; in one example, tens of thousands of voters' registrations were put on hold because information on their applications wasn't an exact match with information in voter databases. There were also reports on Election Day of long lines, a problem exacerbated by some technical issues in the state's second-largest county, and voters not being offered provisional ballots when they should have been.

If Abrams' team took this case to court, their argument would be that as many as 18,000 voters could have been disenfranchised; had Abrams received that many additional votes, she would be able to force a runoff election in December. Abrams' lawyers, however, say no decisions have been finalized and they are "considering all options," one of which would involve a judge reopening the certified results to address potential irregularities. Kemp declared victory last week, and his campaign argues Abrams is trying to "count illegal votes" and that his lead is too great for any remaining uncounted ballots to make a difference.
