Hurricane Irma may be gone, but days of darkness and devastation are just beginning in Florida.Residents could go for days without power after the storm uprooted homes, trees and power lines, leaving 4.4 million customers without electricity statewide in simmering temperatures, officials said."Temperatures will be around 90 for many, especially central and southern Florida for the next several days," CNN meteorologist Taylor Ward said. "High humidity will make it feel like the low to mid-90s. While it isn't above normal, it's certainly warm and humid which is miserable without power." 599

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

In a room of blue serenity, Amelia Moutin prepares for 90 minutes of what she describes as a completely unique sensation.“I think if you let yourself go, it takes about 30 minutes, and then once you kind of settle in and let your mind and body meld together, it’s such a euphoric-relaxation experience that is like none other,” Moutin described.The practice is called floating.“Technically, you lay in 10 inches of water, and 1,100 pounds of Epsom salt. And so, with the buoyancy of the salt, you float right on top of the water,” Samana Float Center owner Heather Clift said.Another term for it is sensory deprivation. The 94-degree water makes it challenging to know where your skin and the water meet creating a feeling of weightlessness. Clift says it was created by a gentleman named John C. Lilly in the early 1950s.“Sensory deprivation is where we void you of all of your senses, so with no light and no sound, there’s no smells in the float tank and there’s no real feeling,” Clift said.Moutin has been floating for a year now, and she tries to go once a month.“It’s kind of like floating in your own little ocean, but you have no fear at all. There’s no sharks, there’s no tide, there’s no possibility of drowning, so there’s literally nothing that can take away from the experience,” Moutin said.With no distractions, Moutin says she’s able to completely let go, relieving herself from the stressors of life. According to Clift, floating can help people who live with anxiety, PTSD, high blood pressure and insomnia among many other things.“It takes you from your sympathetic nervous system, which is your fight or flight, that’s what keeps you alive, and it puts you into the parasympathetic nervous system. And that is called rest and digest,” Clift said.Clift says shutting down your nervous system causes your body to drop its cortisol levels and replace it with dopamine. Dopamine is the hormone that makes our body feel happy and satisfied. It also boosts your immune system.Before the pandemic even started, Clift says the self-cleaning process of the tanks was already very effective at killing germs.“So, if there was anything that could live in 1,100 pounds of Epsom salt, the hydrogen peroxide would cling to it, it would go through the filter, and the UV light would blow it up, so it is impeccably clean," Clift said.However, in case that’s not enough, they’ve also started using ozone to clean all surfaces.“It kills SARS, coronaviruses…up to 99 percent,” Clift said.Clift says many people have made floating a priority this year because they need it now more than ever. Moutin agrees.“Ultimately as a world, we’re experiencing a traumatic event together, and trauma creates stress and issues in our tissues as we like to say,” Moutin said.Even if you don’t notice any physical health benefits, Clift says floating is a great way to relax.“I tell you to take a nap on some water for 90 minutes. How often can you do that? It’s really a special thing. Everybody should float at least once in their life,” Clift said. 3047
