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

IMPERIAL BEACH (KGTV) -- Some South Bay parents said they are frustrated with their internet company after they learned of planned outages during the middle of the school day.Michael Crawford’s daughter is in her first year of high school and like many local students, is starting the year online. Crawford said the transition to virtual learning has not been easy for her. When he learned of the Cox communications outage planned for Tuesday, Crawford said it only added insult to injury. According to a notice he received on his door Friday, the planned service outage was slated to begin at 5 a.m. and last until three in the afternoon.He called Cox Communications, but did not get any answers. “I spent an hour on the phone with them. The lady seemed very sympathetic at first and then she [came] back on the phone and said there’s nothing we could do about it,” Crawford said.His neighbors received the same notice about the planned outage. Crawford questioned why the company doesn’t perform the work later in the day or on the weekends.“I pay them 0 a month for my services and that’s just my house,” Crawford said. “This is a lot of money they’re making and I don’t see why they can’t just pay some overtime for a Saturday. We’re all making sacrifices right now and even the big companies need to make the sacrifices as well.”A Cox Communications spokesperson confirmed the outage due to network upgrades. She said the time on the notice is a window and the average time that a customer is without service is two hours.“We recognize the inconvenience to our customers,” said spokesperson Ceanne Guerra. “Our crews are working really hard to complete this work as quickly as possible. This work is going to support their changing needs as they’re working from home and schooling from home.”Guerra said while they do work during off-peak hours, it is not possible to do so all the time.ABC 10News contacted the Sweetwater Union High School District regarding what students should do during any internet outages. “We ask students to work with teachers individually to ensure they receive their assignments and can work offline as best possible,” said spokesperson Manny Rubio. 2192

If you thought your 2020 stress would magically disappear after the yelling stopped, you might have been surprised to find that you were still worried after the results of the presidential election.“For the majority of people, the stress actually didn’t decrease,” said Vaile Wright, a psychiatrist and also a member of the American Psychiatrist Association. The group recently released some numbers that might explain your extra high heart rate.According to the survey by the APA, 17% of Americans did have their stress go down. However, almost 30% said their stress increased.And it’s not a party issue. Over 80% of Democrats, Republicans, and Independents all listed the future of our nation as a significant source of stress“It’s not just whatever side won, it happens to be everybody right now really being concerned about the future of the nation,” said Wright.And three-fourths of Americans are still seriously stressed about the pandemic“We’ve seen increased levels of stress related to the federal response around the pandemic and that really does come down to the inconsistent messaging that we’re seeing. Different people are disproportionately affected by the pandemic specifically, but I don’t think anyone is related to the stress of it, especially as the numbers continue to climb,” said Wright.But it’s not all doom and gloom. Vaile says that there are some things happening that may help lower your blood pressure.“If we can hear some more good news, health news, like effective vaccines move to the market. The more that we have information that’s clear and consistent, that’s science based and that comes from reputable sources, I think those are the kinds of things that can reduce stress,” said Wright.Better coronavirus news combined with the possibility that President-elect Joe Biden can do a better job uniting the country can give Americans something to hope for as we head into 2021. 1918

In a heartbreaking Facebook post, a Maryland animal shelter announced they found a puppy with its ears cut off tied to a tree in Baltimore. BARCS say they got a call saying someone had found two dogs tied to a tree and several other puppies in an empty lot. When the officer arrived, they found one of the puppies was bleeding from the head and the other puppies were for sale. The puppies were immediately taken to BARCS where they were seen by a vet. They named the injured dog Claude and determined that his ears were removed using poor instruments, like household objects, leaving him with tissue damage, pain, and infection. Claude is only 10 weeks old and BARCS says he is trying to do normal puppy things, but cannot because of the pain. He received emergency surgery but the veterinarians had to remove untreated infected tissue, so he lost even more of his ear structure. BARCS is now asking for money so they can continue to help Claude so he can find a loving home and recover. You can donate by clicking here, but make sure your gift is dedicated to him by including his name in the additional comments section of the donation form.  1198
