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

If you’re shopping for a car, you may already know that buying used is a smart move that greatly expands your choices. The key is knowing where to look for them.Buying a used car will not only save you money but also allow you to shop higher-end brands, says Ivan Drury, Edmunds.com’s senior manager of insights. For example, maybe you wanted a new Toyota Camry. Instead, he says, you can save about ,000 and get a 3-year-old Lexus.Because of the bankruptcy of Hertz rental car agency, along with the many cars coming off lease, there are a lot of used vehicles to choose from, says Jeff Huang, who attends auctions as the remarketing sales supervisor at Westlake Financial Services. “A good used car is a real value proposition — and there are definitely deals to be had,” Huang says.Shoppers looking for great bargains will find them in cars older than 7 years, says Mark Holthoff, used car editor at Klipnik, a website for used car enthusiasts. “That’s because the depreciation curve has mostly been flattened,” he says. For example, a 2014 Mercedes-Benz E-Class sedan, costing ,000 new, now sells for about ,000.Shop in the right placeNew cars are sold only by franchised dealers, but used cars can be purchased from a variety of sellers:Used car departments at new-car dealerships.Used car superstores such as CarMax.Online used car sellers such as Carvana, Shift and Vroom.Car rental sales lots.Independent used car lots.Private parties.Public auctions.You’ll typically find the newest and more expensive models at new-car dealers’ used-car lots, the only place to turn if you want a certified car with a warranty and factory financing. Prices are likely to be higher than other lots’ but negotiable.National used-car chains such as CarMax, online retailers and rental car agencies also offer newer cars, often with factory warranty remaining. You can also get a loan and buy extended warranties. Prices are typically no-haggle.Independent lots, private parties and public auctions typically deal in older or cheaper cars. The upside is that you may find a 20-year-old one-owner cream puff, cheap. It does happen. But most cars have had several previous owners, and a checkered past is not rare. Plus, you’ll have to arrange your own financing.Adjust your expectationsThere is a built-in risk-versus-reward element to used car shopping: The more you’re willing to spend, the less chance the car will need repairs and overdue maintenance. Here’s an overview of the three price levels of used cars:High-end used cars: If your budget is over, say, ,000, you might consider getting a certified pre-owned (CPO) car from a dealer. Shopping for a CPO car is easier because it’s pre-inspected and comes with an included warranty. While you’ll have to pay a premium, you’ll also be able to buy a car with more modern technology and safety features. Of course, you can always buy a non-CPO car and purchase an extended warranty.Midrange used cars: A sweet spot for used car buying is a 3-year-old vehicle coming off a lease. Many of these cars will sell for 40% of their original price and still retain a new-car feel, according to Drury. Another source of near-new bargain-priced vehicles is car rental lots. According to an iSeeCars analysis, Hertz vehicles are selling for an average of ,389 below market value.Older used cars: Many people are afraid that cars from 7 to 15 years old will require costly repairs. But Holthoff points out that new cars can effectively cost the owner ,000 a month in depreciation.“You might have to spend money on a repair, but depreciation is a constant,” he says.To offset repairs, set aside 0 a month so sudden mechanic bills won’t deplete your savings.It’s best to buy older cars from private-party sellers because you can get a better idea of the mechanical condition, Holthoff advises. A used car dealer will show you the vehicle history report, but a private party might have the service records and can answer many other questions.Look for unexpected valueThe used car market is vast and, if you can spot an outlier, you can save big money. Here are a few examples of how to find that diamond in the rough:Cars that haven’t been recently redesigned will sell for less. Check car sites such as Edmunds.com to find out when the last time major changes were made to a model.While there is a stigma to buying a used rental car, the vehicles are well-maintained and priced lower than buying from dealers, Drury says.If a car dealer’s vehicle history report shows you are looking at a former rental car, leave and buy a similar one directly from the rental agency’s sales lot. You’re likely to find it cheaper.Be willing to travel to an area where the car you want is less popular. For example, all-wheel-drive vehicles sell for less in the southern U.S., where winter driving isn’t a factor.Be willing to travel to a more competitive market. A Honda dealer with a city to itself has less pressure to dicker on a CPO vehicle than a dealer in a city with three or four rivals.Used luxury cars often offer the biggest savings, according to Holthoff. The money you save on the purchase can be used if any repairs are needed.More From NerdWalletDon’t Fall for COVID-19 Student Loan Relief ScamsGet Your Finances Ready to Refi Student Loans5 Reasons It’s Smart to Lease a Car Right NowPhilip Reed is a writer at NerdWallet.

They threw a boulder thru our office window and took office equipment," McCarthy wrote Monday.CNN has reached out to McCarthy's office and the Bakersfield Police Department. 553

If you've notice delays in the delivery of your packages or higher prices for some of things you order, a shortage of truck drivers may be to blame. A new program is hoping to bring some relief, but some worry it'll make roads less safe.The program trains teenagers to drive cross country. Elijah Amos is one of the teens involved with the program and working towards getting his commercial driver’s license.“I think we really did it for me is driving,” Amos says. “Because I really like driving and I feel like you get paid a decent amount of money. Just to drive.”But since he's 18, he won't be able to drive from state to state. He'll have to wait until he's 21. However, a new government pilot program will soon allow some drivers as young as 18 to drive cross country.“I feel like it would open up more job opportunities,” Amos says. “And maybe it opened up the eyes to some of the younger people maybe like actually try and do it.”The program would be available to some members of the National Guard and others with military experience. But in March, House Republicans introduced a bill to lower the commercial driving age to 18 for anyone driving state to state. Their goal? To fight a nation-wide truck driving shortage.Quincy Jones, who directs Sage Truck Driving School, says it's been challenging to attract driving students. He says ultimately, consumers pay the price.“Shipping costs get passed down the consumer,” Jones says. “So if there's a shortage, those aren't getting picked up as frequently. And so who pays them? We do. We all pay. Consumers do."The American Trucking Associations says the shortage is expected to hit 63,000 this year. But with motor vehicle drivers aged 16 to 19 being nearly three times more likely than people over 20 to fatally crash, not everyone believes teen drivers are the solution to the problem.“Younger people have less experience driving for all types of vehicles,” says Norita Taylor, with the Owner Operators Independent Drivers Association. “And so the crash rates are higher for younger people, and so we think it would be a dangerous idea.”Sponsors say the bill would require teens complete at least 240 hours driving supervised by a veteran driver.  2240
