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

House Speaker Nancy Pelosi’s office is responding to criticism after she got her hair done inside a San Francisco salon, amid a citywide coronavirus restrictions on salons.A statement from her office acknowledges Pelosi and her staff relied on the information provided by someone at the salon about what was allowed by the new city regulations that went into effect last Friday, according to multiple outlets.The statement came after Fox News shared a video showing Pelosi inside the salon. Fox talked to the salon’s owner, Erica Kious, who told the news outlet, “it was a slap in the face” that Pelosi could go in and “get her stuff done” while the owner and others can’t work.Kious said it was an independent stylist who rents a chair from her."This business offered for the speaker to come in on Monday and told her they were allowed by the city to have one customer at a time in the business," Pelosi's Deputy Chief of Staff Drew Hammill said in the statement. "The speaker complied with the rules as presented to her by this establishment."The statement also says Pelosi wore a mask except for a brief time when she was getting her hair washed.The new restrictions in San Francisco say hair salons can operate outdoors, and that some procedures, like color and chemical treatments, still cannot be done. 1316

Housing and Urban Development Secretary Ben Carson detailed his wife's involvement Tuesday in picking out a dining room set for his office, telling a House subcommittee, "I left it with my wife."Carson said that his wife, Candy, selected "a style and a color" of the furniture set that ultimately cost HUD ,000."A style and a color was selected by her with the caveat that we were not happy with the pricing and they needed to find something," Carson told lawmakers.He went on to defend her, "If anybody knew my wife, they would realize how ridiculous this was. She's the most frugal person in the world."A HUD spokesperson had previously told CNN in a statement last month that "Mrs. Carson and the secretary had no awareness that the table was being purchased." Internal HUD emails indicated that the Carsons had picked out the furniture.Carson said Tuesday the issue of replacing the dining room set was raised "because people were being stuck by nails, the chairs collapsed with somebody sitting in it, it's 50 years old.""I said, 'OK, we can potentially do that.' I asked my wife also to help me with that," he told lawmakers."They showed us some catalogs. The prices were beyond what I wanted to pay. I made it clear that just didn't seem right to me. And, you know, I left it with my wife," he said.Carson argued that he wasn't concerned about the furniture because he had more important issues to handle as HUD secretary.Carson said he first heard of the ,000 price tag after it was reported and "immediately" canceled the order from the interior design firm Sebree and Associates in Baltimore, Maryland. He testified that the money spent on the dining set was returned to the US Treasury."I'm not really big into decorating. If it was up to me, my office would probably look like hospital waiting room," quipped Carson, who previously worked as a neurosurgeon.He said his wife is not involved in any other decisions regarding the purchasing of furniture for HUD.Carson was also asked about inconsistencies in the messaging from the agency regarding how involved he and his wife were in the process to purchase the dining set compared to what internal HUD emails indicate. The emails were released through a Freedom of Information Act request."There appears to be some contradiction in the record about your statements to the press indicating early on that you had no knowledge of this purchase," Rep. David Price, D-North Carolina, said to Carson.Carson denied he ever spoke directly to the press.When Price pointed to the statement that the HUD spokesman provided to CNN at the time, Carson distanced himself from his spokesman's comments."I would respectfully tell you what I said. I can tell you what I did. I do not intend to be responsible for what anybody else said," Carson said.Carson then said that the content of his statement made via Facebook?where he personally addressed the issue "is quite accurate." 2953

If you live with someone who has opposing views about the COVID-19 pandemic, it can make living situations awkward.Hunter Stanfield is an assistant professor of family science at Lipscomb University. When approaching someone about their views on COVID-19, and their habits, he said it’s best to remain calm and open-minded.“It is throwing everyone for a loop,” Stanfield said, “So instead of saying that you’re really getting worked up about this, that’s probably not the best initial approach. It may be ‘I can see that this is really upsetting to you, can you tell me a little bit more about that?'”He said trying to understand, before attempting to be understood, is a good starting place. “Am I willing to consider their perspective, or am I in this to prove them wrong? Which in the end gets us nowhere in all of this, so I think those basic things are really important and critical.”If you know why someone’s habits are a certain way, it’s possible to compromise.“I know some people say compromise is a dirty word, in this case, I think compromise really gets at the fact that I’m wanting to meet someone or be a part of someone’s life the best I can," Stanfield said.If the social awkwardness persists, a ton of people is going to therapy to sort it out right now.“I sometimes equate therapy to taking your car in to get an oil change. Sometimes it’s good to go in for a routine tune-up.”Lipscomb University actually provides low-cost therapy for folks in the community that need it.
