When Lauren Arrington decided to study the lionfish for her sixth grade science fair, the 12-year-old had no idea she would make a discovery that would surprise conservationists.

The Jupiter, Florida, youth had long been interested by the lionfish, an invasive species known for its spiky (and venomous) fin rays. Along with her father, who has a Ph.D. in fish ecology, Lauren worked on determining how far lionfish can make it in water that's not salty. Her dad believed they wouldn't be able to survive in salinity of less than 12 parts per 1,000, which is about a third as salty as ocean water. Lauren decided to go lower than that, and slowly went down to six parts per 1,000. The fish continued to do well, but Lauren stopped there, afraid she might kill her subjects if she dipped below that number.

Lauren's research shows conservationists that lionfish might be able to make their way into more waters than previously thought. North Carolina State University ecology professor Craig Layman used her findings and expanded upon them in a new study; he was sure to give Lauren credit for her discovery. Catherine Garcia

The U.S. Justice Department filed a civil rights lawsuit against Ferguson, Missouri, on Wednesday, with Attorney General Loretta Lynch saying the city's residents have "suffered the deprivation of their constitutional rights — the rights guaranteed to all Americans — for decades. They have waited decades for justice. They should not be forced to wait any longer."

The suit cites a "pattern or practice of conduct that deprives persons of rights, privileges, or immunities secured or protected by the Constitution or laws of the United States" and alleges officials in Ferguson use illegal practices in conducting stops, searches, and arrests; by using excessive force; and in discriminating against African Americans. The Justice Department is calling on the federal court to force Ferguson "to adopt and implement policies, procedures, and mechanisms that identify, correct, and prevent the unlawful conduct."

On Tuesday, the Ferguson City Council approved a revised version of a consent decree that was intended to fix problems in the police department and municipal court found during an investigation following the fatal officer-involved shooting of Michael Brown in August 2014, the St. Louis Post-Dispatch reports. The Justice Department says the revisions to the consent decree will likely be challenged. Catherine Garcia

Much has been said about the lack of substantial roles for women in Hollywood films — female characters are disproportionately underrepresented and hypersexualized, a 2013 study found. The issue goes far beyond who is directing the movie, too: A character is, after all, first conceived in a script. That's where Ross Putnam comes in.

Putnam is a producer who has created a Twitter account to highlight the fact that women are written as sexual objects right from the start. "These are intros for female leads in actual scripts I read. Names changed to JANE, otherwise verbatim... Apologies if I quote your work," Putnam writes in his bio.

Here is a look at some of the most telling of the bunch. Jeva Lange

Former Hewlett-Packard CEO Carly Fiorina suspended her bid for the Republican presidential nomination, she announced Wednesday.

"While I suspend my candidacy today, I will continue to travel this country and fight for those Americans who refuse to settle for the way things are and a status quo that no longer works for them," Fiorina said in a statement.

She fared poorly in both the Iowa caucus and New Hampshire primary. It didn't take long for the Democratic Party to weigh in on Fiorina's announcement. Julie Kliegman

On Wednesday, Iranian state television aired previously unseen footage of the U.S. Navy crew members detained by Iranian authorities last month. In one of the video's segments, an unidentified sailor appears to be crying, red-eyed and seemingly wiping away tears with a tissue.

The footage was reportedly shot during the 16-hour period on Jan. 12 when 10 sailors were detained after two small U.S. navy boats allegedly drifted into Iranian territory. The Pentagon says that one of the boats was experiencing mechanical problems.

While previously released photos of the sailors showed them on their knees with their hands behind their heads, Secretary of State John Kerry and the Obama administration had thanked Iran for its "quick and appropriate response" and for providing the soldiers with "blankets and food and... their return to the fleet." The sailors' release was largely celebrated as a diplomatic victory.

However, The Washington Post reports, this new footage suggests that, despite being released unharmed the next day, the captured sailors' experience was "still stressful."

Republican National Committee Chairman Reince Priebus wouldn't be thrown by Michael Bloomberg entering the presidential race as an independent. In fact, he thinks it could help his party, telling CNN's Wolf Blitzer it's "no skin off our back."

"Yeah, I don't really view it as a third party, I just view it as another Democrat," Priebus said Wednesday. "So you get two Democrats running and splitting their vote."

Priebus then cited some well-known actions of the former New York City mayor.

"He's been fighting and pounding away at Republicans for how long now?" Priebus said. "He wants to take all the guns away, he wants to tax Slurpees and sodas. The guy's a liberal Democrat."

As part of Amazon's ongoing quest to run every aspect of your life, the tech giant is testing a free sommelier consultation service. Customers can leave their number between 12 p.m. and 5 p.m. and wait for a call from a licensed professional who can talk them through buying wine on Amazon, The Wall Street Journal reports.

For now, the service is only available in Japan, but Business Insider speculates Amazon will make the option available elsewhere. Julie Kliegman

Ben Carson evacuated New Hampshire hours before the primary, leaving his own election party to revel without him. Only, there wasn't actually much reveling: Beating only Jim Gilmore, Carson skidded into a dismal eighth place, which doesn't do much to stoke a celebratory spirit.

Consequently, the party was a bit of a bust. It peaked with 50 attendees and while the campaign had optimistically set up two bars, "neither was inundated," The Guardian reports. Even worse, "A woman working behind one [of the bars] spent much of her time knitting a blanket."

Carson's campaign manager, Bob Dees, stressed that there is no cause for concern. "We didn't throw the kitchen sink in here. He'll perform very well in South Carolina. He could easily be in the top three and above in South Carolina. He could easily win in South Carolina," Dees said. Jeva Lange
