If you're interested in fish who are scary-looking, poisonous and chock-full of elaborate defense mechanisms, look no further than the stonefish, a genus of fish that populate coastal waters of the Indo-Pacific region.As if their deadly venom and spiny exteriors weren't enough, scientists at the University of Kansas have found that stonefish also have a hidden switchblade on their face that they can flick out whenever they feel like they're in danger.Scientists call the bony, blade-like protrusion a "lachrymal saber," because it is located on a bone under the fish's eyes. Also, "lachrymal saber" is just a really metal-sounding name.William Leo Smith, associate curator and associate professor of ecology & evolutionary biology at KU, first started to understand how the lachrymal saber worked 15 years ago, when he was dissecting a stonefish he kept as a pet.This is a game-changerHe tells CNN the mechanism isn't just a cool new discovery (although it's that, too). It also changes the scientific understandings and classifications of this particular type of fish."It opens up these ideas of ecological questions. Muscular systems, bone systems, nervous systems all came together to form this. What led to its evolution or use?In other words, he says, "Why do we see this accumulation of so many horrible things on one fish?"The lachrymal saber is housed inside the fish's head, and they use their cheek muscles to deploy it. Though some stonefish are venomous, the saber is not.It could be a sex thing, tooSmith says he and his fellow researchers have reason to believe the saber isn't just for warding off predators: It could be a sex thing, too."There is evidence pushing towards that," he says. "They may use this in battles with other members of their species, like ram horns. It may also be involved in courtship behaviors."Oh, and the sabers glow."It's fluorescent green," Smith says. Since stonefish rely on camouflage for both protection and hunting prey, Smith doesn't think the fluorescence has a defensive purpose like, say, warning off predators.There are 134 described species of stonefish, and by Smith's observation, all of them have some form of lachrymal saber.  2202

How do you re-capture a gigantic runaway pig?According to the San Bernardino County Sheriff's Department, deputies received a call on Saturday that a pig "the size of a mini horse" was roaming a local neighborhood.Deputies were quickly able to track down the swine and determined where he lived, but still had to figure out how to corral him and get him home. It turns out, pigs don't need to be corralled if there are Doritos on hand.According to the San Bernardino Sheriff's Office, Deputy Ponce had a bag of Doritos on hand in her lunch box and was able to lure the pig back to his home by laying a trail of chips on the street.The pig made it safely home and deputies were able to secure the gate. Ponce called the journey "fun."The Doritos appeared to be of the Cool Ranch variety. It's unclear if the pig would have been swayed by Nacho Cheese chips.  880

House Speaker Nancy Pelosi and Rep. Jamie Raskin, D-Maryland, introduced legislation Friday that establishes a Congressional commission that would be able to investigate a President's health under the 25th Amendment.While President Donald Trump's health has come into question following his COVID-19 diagnosis, Pelosi and Raskin insisted that while Trump's health prompted their bill, it would not be used to remove him from office.Instead, Raskin said the commission would be a bipartisan effort that would be set up in case the health of other presidents came into question.Passed in 1967, the 25th amendment to the U.S. Constitution spells out the presidential line of succession.The amendment has four sections:1- When a president dies or resigns, the vice president finishes the term.2- When there is a vice presidential vacancy, the House and Senate votes to confirm a replacement nominated by the president.3 - When a president needs to temporarily cede power, he or she can hand the duties to the vice president who then becomes the acting president.4 - The vice president and a majority of secretaries can vote to remove the president if the president is "unable to discharge the powers and duties of his office. The section also grants power to a body "established by Congress" to invoke the amendment and transfer power to the Vice President.Raskin said his bill would establish that "body" that could investigate the health of the president. For Congress to invoke the 25th Amendment, the Speaker of the House and the President pro tempore of the Senate must provide "written declaration" that the President is "unable to discharge powers and duties of his office." Sen. Chuck Grassley, R-Iowa, is the current President pro tempore and will unlikely make such a declaration. In addition, the President could object to the Congressional body's findings. Reports surfaced later on Thursday that the House is planning to introduce legislation to institute a commission to evaluate the president's health.Pelosi then criticized the White House for not stating the president last submitted a negative coronavirus.“I think that the public needs to know the health condition of the President. There’s one question they refuse to answer. Before he got the virus and admitted to it, when was his last negative test? When was his last negative test? To make a judgment on the actions that were taken after that,” Pelosi said.Editor's note: A previous version of this story incorrectly stated that Congress has no authority to remove the president under the 25th Amendment. 2582

IMPERIAL BEACH, Calif. (KGTV) -- It appears the “Don Juan” thief one woman says loves stealing from women on first dates is a wanted man.Last Friday, 10news recounted Elizabeth’s so-called “date from hell.”  Elizabeth, 23, says the man is a good-looking guy in his late 20s who was a Facebook friend for two years.  They had mutual friends in common but had never met. RELATED: 'Don Juan' thief targeting women, some on first datesHe messaged her recently, asking her out to a sushi lunch. She agreed, but during the drive, she says he fidgeted with his blinkers and asked her to exit the SUV to make sure they were working. She agreed, and that's when he took off, with her purse, wallet, and sunglasses.When she posted his photo on Facebook, she says she got a flood of responses: dozens of other women with similar stories of theft."One woman said, 'He told me he had a gift for me in the trunk, and as soon as I got out, he drove off with my purse and several hundred dollars,'" Elizabeth recalls.She says none of the women called police because the man told them he had friends in a cartel.  But apparently at least one woman did. Sources tell 10news an arrest warrant has recently been issued for him after a different local woman accused him of stealing money and other property valued at more than 0.10news has also learned the man pleaded guilty in 2015 to embezzling from his employer - Walmart - and received a sentence of three years probation.10new has not identified the man in Elizabeth’s case because detectives haven’t officially confirmed he is the wanted man.If you have any information, please call San Diego Police at (619) 531-2000. 1700
