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 Majority Whip Steve Scalise has been released from a Washington, DC, hospital following a "successful" surgery, according to MedStar Washington Hospital Center.The hospital released a statement Saturday saying the Louisiana Republican was discharged from the hospital and "the planned surgery was successful." The congressman "will be recovering at home for the next several days," the statement added.The congressman's Twitter account also shared the statement. CNN reported earlier this month that Scalise was beginning a "series of planned, inpatient procedures" while continuing to recover from injuries he sustained in a shooting last year.Scalise suffered a gunshot wound last summer when a gunman opened fire at a congressional baseball practice in Alexandria, Virginia.In September, Scalise returned to Congress for the first time since the attack, saying at the time that he is "a living example that miracles really do happen."  957

If it's been a while since you've booked a flight, travel insurance is that thing that pops up at the end of a sale.“At the end, they’re going to say, ‘Hey, this many people bought travel insurance, don’t you want to buy travel insurance too?’ And I think a lot of people generally, before COVID, would think, ‘Oh they’re trying to upset me and move along,’” said Michael Parrish DuDell, chief strategy officer for Couponfollow.com. “But what we’re seeing, in fact, is that more and more people are saying, ‘I want that insurance I want to protect my future travel.’"Couponfollow.com was designed, DuDell said, to save consumers both time and money. He says the company is always asking consumers about their money and how they spend it.“As we looked closer at how people are traveling, where they were spending their money, where they were allocating their time, we found these little niche interesting areas,” DuDell said.He says those areas include things like travel insurance.“What we found is that 75% of people who had already booked flights had purchased trip insurance. That was a staggering number that is a 55% increase than what is thought of as the norm,” DuDell said.So, why the increase? Travel anxiety amid the pandemic is likely a big part of it.“There is so much uncertainty in the world right now, and of course that’s around the pandemic, but there’s other kinds of uncertainty too and I think people feel like they’re taking a strong risk in general when they’re traveling,” DuDell said. "So if they can mitigate risk in other areas, they’re willing to do that, to spend the money behind it.”Leslie Tayne, a financial attorney, author and frequent flier said, “There are a lot of caveats to whether travel insurance for airline purposes makes sense right now and frankly because the airlines allow you to make changes without a cost and last minute, there’s really almost no reason why you would get travel insurance.”She says these days, airlines are more accommodating than ever. And because there's been so much industry disruption surrounding travel, the future is being rewritten now.“I definitely believe they’re going to rewrite the travel insurance, they’re being investigated right now,” Tayne said. “It's being taken up in Congress in terms of the validity of the travel insurance and there’s some concern that travel insurance might be what’s termed either a ‘scam’ or a ‘money-making proposition’ that’s not really beneficial to the consumer.”In March, the House Oversight and Reform Subcommittee on Economic and Consumer Policy launched an investigation into whether travel insurance provided any “meaningful protection” for consumers. The investigation was spurred amid the onset of the coronavirus pandemic, when many travelers were canceling trips as states began implementing stay-at-home orders.“The evidence shows consumers are purchasing standard travel insurance products, thinking they will be covered if they cancel their trip because of coronavirus,” Rep. Raja Krishnamoorthi (D-IL), the subcommittee’s chair, said in March. “Yet, companies like Allianz, Travel Guard, and Generali are refusing to cover those claims. In the process they are encouraging dangerous travel.”So, when it comes to whether you "need" that insurance, Tayne says weigh your risks, consider where you're going and what you'll be doing.“My recommendation is to try to understand what the restrictions are and what you could use the insurance for when would it apply to you,” Tayne said.Tayne said if you're in a situation where it makes sense, don't make an insurance decision on emotion. Think of it as a business decision, and these days, we're all in the business of saving time and money. 3719

If you’re looking for the ultimate piece of sports memorabilia, you may be in luck. But it may cost you.Christie’s will launch an auction next week, which include a pair of game-worn sneakers worn by his “Airness” Michael Jordan. Some of the proceeds from the auction will go to the NAACP’s Legal Defense Fund.The highlight of the auction is expected to be a pair of game-worn sneakers from Jordan’s rookie season. The auction house projects that the sneakers will sell for between 0,000 and 0,000. The pair is one of 11 items from Jordan’s playing days up for auction.Then known as “Nike Air Ship,” Jordan wore these shoes, sized 13 for his right foot and sized 13.5 for his left, were used for a few games early in the 1984-85 season. These shoes were the prototype for the original Air Jordans released to the public after his rookie season.Another pair of shoes up for auction, which are expected to sell for more than ,000, were worn by Jordan during the 1992 Olympics as a member of the Dream Team. These are a pair of Jordan 7s that Jordan wore during the Gold Medal game.The shoes were gifted by Jordan to a receptionist at the Ambassador Hotel in Barcelona. The shoes were given to the receptionist as a show of gratitude after the Dream Team’s stay there during the 1992 Olympics.“The pieces we’ve put together for this auction are truly unique, and will have deep resonance for Jordan fans, sneaker connoisseurs and pop culture collectors alike. Additionally, we are pleased to be able to donate proceeds from one of the sale’s most exciting highlights to the NAACP Legal Defense Fund,” John McPheters, Co-Founder and Co-CEO, Stadium Goods, said. Stadium Goods is assisting Christie’s in the auction. 1728

If you ask most Americans, finding work isn't that difficult these days. But getting paid enough to get by still remains a problem.The percentage of residents who think jobs in their area are plentiful spiked to 50% last month, the highest reading since the Pew Research Center began asking the question 16 years ago.Those perceptions match reality. 362
