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, Calif., (KGTV) — After six grueling days on the fire line, members of the San Diego-based Strike Team called to fight the Kincade Fire are back home. 10News met with the fire crew from Imperial Beach, who said this was the first time in 11 years that they were called to assist in Northern California. Today, they were back on duty, just hours after their arrival. It's just another day at the Imperial Beach firehouse. Fire Engineer Cory Cooper, firefighter Nick Morales, and Captain Ehren Kahle are cleaning up their ride, Engine 39, after a long trip up north. "It was just kind of a gentle immersion into chaos," Kahle said. Last Friday, the three were part of a large San Diego-based Strike Team called to assist in Sonoma County. As soon as they arrived, they headed straight to the fire line. "It started out with light smoke, which progressively got worse, to a point where my engineer had difficulty seeing the road at some point," Kahle said. Buildings had crumbled, citizens were in chaos. But they were there, fighting the explosive flames, seemingly non-stop."We rest when we can," Kahle laughed. Once the spread slowed down, the team headed back home. The men arrived at 11 p.m. on Thursday. While firefighters in larger departments are given a 24-hour rest period, these guys with the small Imperial Beach department are already back on shift."We're right back to our normal routine."It's day-to-day calls like these, as well as being part of a large Strike Team that reminds Captain Kahle of the true camaraderie of the fire service. "Although I may be going out on a Strike Team with men that I have never worked with or never even met in my entire life, you can probably take a firefighter off of an engine from San Diego, Coronado, National City, or Poway, throw them onto their engine, and they will drive right into that crew and be able to function," Kahle said.

However, it turns out that Hidalgo wasn't fired. According to Roman Stone Works, he returned to work two days after sharing the meme and then walked off the job on his own last Wednesday.Hidalgo confirms that happened, saying he went in after the text message because he wasn't entirely sure he was fired. However, he quit a few days after returning to work."With the bad blood, I didn't want to work there anymore," he said.Jan Jeffrey Rubenstein, a lawyer representing Roman Stone Works, says the company's owners have been receiving death threats at work and home. They say the backlash is unfair, especially when Hidalgo quit on his own."Roman Stoneworks and its owner and personnel have been subjected to significant monetary damage, as well as threats, profanity and harassment by phone and email," Rubenstein's statement read, in part. "Due to the backlash from these false claims, my client's webpage has had to be removed, and the individuals involved have been inundated with calls and emails.""I never meant for people to blow it up like that or spam their company or defame their name," Hidalgo explained.He might delete the post, but believes the "damage is done."Hidalgo is now waiting to hear if he will get a new job after an interview."Watch what you share sometimes because it could get you in trouble. It can look bad on you," Hidalgo added.Read the entire statement issued by Roman Stone Works' lawyer below. 1436

In advance of hurricane season, Florida Power and Light is reviewing plans to make sure power is restored quickly after a storm. This week the company is holding its annual storm drill, simulating a Category 3 hurricane. During the drill, the company says it is incorporating lessons learned from Hurricane Irma, which knocked out power to 6.7 million electrical customers, according to the U.S. Energy Information Administration (EIA).EIA reports the rate of electric service restoration following Hurricane Irma was faster than Hurricane Wilma in 2005. Five days after Irma’s landfall, the share of customers without power had fallen from a peak of 64 percent down to 18 percent -- a recovery rate of about 9 percent of customers per day.Power outages during Wilma declined from 36 percent of customers to 16 percent by the fifth day after landfall. This is an average recovery rate of about 4 percent of customers per day. FPL credits the improvement to money spent on infrastructure improvements. Since 2006, more than 860 main power lines were hardened; within the next five to seven years FPL wants to harden all of them.Strengthened power lines perform approximately 40 percent better than non-strengthened lines, FPL said.This year, FPL plans to undertake the following additional initiatives to improve the reliabilityof service: 1416

I haven’t set foot in a grocery store in nearly four months.With a 10-month-old baby to think about, my husband and I have kept trips to the store to a minimum out of an abundance of caution during the pandemic. We’re fortunate to have just about every grocery delivery service at our disposal — and we’ve taken advantage.In between orders from Costco, Whole Foods, Imperfect Foods and more, I’ve noticed our virtual shopping habit is changing how we budget. We’re accounting for new grocery-related expenses. We’re also more deliberate about what we buy.Here’s why online grocery shopping could affect how much you spend — and ways to keep your budget intact.MarkupsYou could pay more online than in the store for the exact same item. That’s because some delivery services, or the retailers they partner with, inflate grocery prices to cover fulfillment costs.On Costco’s website, I was met with the message “item prices are marked up higher than your local warehouse. Instacart uses the markup to pay for their delivery service.” The exact price difference wasn’t specified.Same-day delivery service Shipt says its members can expect to pay about more on a order online than in the store. Plan that you will spend a few extra bucks every time you buy groceries online.Extra chargesAt the grocery store, the price you see is typically the price you pay. But online, fees for delivery, service, alcohol, memberships and subscriptions could be tacked onto your bill. Extra charges could range from a couple dollars for a service fee to about a hundred dollars for a membership.“You’re spending more money because it’s a service,” says Jennifer Weber, a certified financial planner in Lake Success, New York.How you use that service can also affect the cost. Often, you’ll pay a premium for quicker or high-demand delivery times. Then, there are tips. Tipping, while optional, is a simple way to support the workers risking their health to provide you with an essential service. Many grocery services set a default tip, so make sure to pick the amount you prefer.SubstitutionsItems could be unexpectedly out-of-stock, incorrect or missing from your delivery. Certain services allow substitutions for unavailable inventory. However, that can come at a higher cost. When the conventional tomatoes I ordered sold out, I ended up with organic tomatoes for more.When using services that charge for pricier replacements, consider opting out of automatic substitutions or allocating a few extra dollars toward your grocery budget as a cushion. Inspect orders closely upon arrival as well and notify the company if you’re charged for forgotten or incorrect items.Impulse purchasesGetting your groceries while sitting in front of your screen isn’t all bad news for your wallet: 46% of consumers say they’ve made fewer impulse purchases since shifting to online grocery shopping in the spring, according to a survey from Magid, a business strategy and research company.“Careful planning and buying only what you intend to is a little bit easier to do online,” says Steve Caine, a partner with the retail practice of Bain and Company, a management consulting firm. “You don’t get influenced quite the same way as you do when you’re walking through a store.”With no enticing candy displays or cleverly arranged shelves to stroll past, you might fill your cart with fewer items. Plus, Caine says shopping online allows you to better keep a “running total” of your purchase, while in the store, you usually don’t know until checkout.Ways to watch your budgetOnline grocery shopping is here to stay for the foreseeable future. These strategies can reduce the strain on your budget.Make a list. Check your fridge or pantry and jot down what you need for the week. “You can think ahead and say, ‘I want to spend 0 or .’ Then, you can do price comparisons for those items,” Weber says.Compare grocery services. Try building a basket on a few different sites to see which offers the lowest price on items. Explore all the costs involved and look for coupons or promotions before checkout.Be flexible. Choosing curbside pickup can help you skip delivery fees, tips and other charges. But if you opt for delivery, note that one-hour or same-day windows could be more expensive. Giving yourself time to plan and pushing it to next-day or two-day delivery can reduce the cost, Caine says.This article was written by NerdWallet and was originally published by The Associated Press.More From NerdWalletWhy Taking Social Security Early Costs Too MuchHow to Renegotiate Your Bills to Save MoneyFeeling Out of Control?
