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

HOUSTON (AP) — A federal judge has rejected a last-ditch Republican effort to invalidate nearly 127,000 votes in Houston. U.S. District Judge Andrew Hanen’s ruling Monday concerned ballots cast at drive-thru polling centers that were established during the pandemic. The judge's decision to hear arguments on the brink of Election Day drew concern from voting rights activists, and came after the Texas Supreme Court rejected a nearly identical challenge over the weekend.The lawsuit was brought by conservative Texas activists who have railed against expanded voting access in Harris County. Hanen said the opponents to drive-thru centers — who were represented by former Harris County GOP Chairman Jared Woodfill— had no standing to bring a lawsuit. He added that people had already voted and that conservative activists had months to bring a challenge sooner.But Hanen still expressed doubts about whether Texas law allowed anyone to vote from their car, even in a pandemic.“If I were voting tomorrow, I would not vote in a drive-thru just out of my concern as to whether that’s legal or not,” Hanen said.Another 20,000 or more voters were expected to use drive-thru polling locations Tuesday, said Harris County Clerk Chris Hollins, the county’s top elections official. Several voters who already used the drive-thru centers rushed to join mounting opposition to the lawsuit, including a Houston attorney whose wife was 35 weeks pregnant when she cast her ballot. She gave birth to twins Friday.The county is the nation’s third largest and a crucial battleground in Texas, where President Donald Trump and Republicans are bracing for the closest election in decades on Tuesday. 1689

If you're feeling a little — or maybe a lot — stressed about the election, you are by no means alone.That's the conclusion of a variety of surveys, which show that a majority of Americans are concerned about violence breaking out from supporters of whoever loses the presidential election, no matter who that is. However, there are ways to reduce election-related anxiety, and they're rooted in acting in one's own best interest, and in self-control, according to experts.The situation is exemplified by clashes seen over the weekend.In Times Square on Sunday, demonstrators in support of President Donald Trump and former Vice President Joe Biden clashed physically. Police separated the two sides and took a handful of people into custody.There were other such encounters, as well, many of which were posted online.The incidents, along with worries about the accurate vote count, the Postal Service properly doing its job on mail-in voting, long lines to cast a ballot, COVID-19 affecting ability to turn out to vote, and any number of other concerns, all add up to create a stressful election season.Experts who analyze election-related security issues agree.Gloria Browne-Marshall is a constitutional law professor at John Jay College, and author of "She Took Justice" and The Voting Rights War, both of which deal with challenges to voting."Because there have been so many uprisings of militia groups, and so many of these different tactics being used to disrupt protesters," Browne-Marshall said, "people are afraid that those entities are going to come out.""If [groups that are willing to do harm] see that they're losing the election, or their candidate is losing the election," Browne-Marshall continued, "they might come out to intimidate voters."Doron Kempel is a security expert, former Israeli Army commander, and founder of the personal security app Bond. He said that he's well aware of the anxiety that voters have."People feel so tense about what may occur, irrespective of whether you're on this or that side of the aisle," Kempel said in a Zoom interview. "Everybody's concerned that whatever happens, people are going to be upset, and are going to get emotional, and maybe there's going to be a little bit of violence."Polling bears that out.Earlier this month, a YouGov / Braver Angels national poll showed that a majority – 56% of people agreed or strongly agree with the following statement: "America will see an increase in violence as a result of the election."That’s far higher than the 11% who disagree or strongly disagree. Thirty-three percent of people polled said they neither agree nor disagree.The numbers indicate that more people are stressed than not.Research shows that there are ways to manage the tension and even turn it into action that's positive and protective."They should all have a voting plan," Browne-Marshall said, as she listed some ways people can reduce anxiety, by foiling any attempts to suppress voting. "And if things get disrupted by violence in the [voting] line, then don't wait till the last minute. Vote early if you can, in whatever state, vote in the way that's safest," she said.Kempel, the security expert, also said that there are measures that all voters can take to protect themselves during election season.First and foremost, said Kempel, there's reason to be more optimistic about the social and political climate, despite the fact that there's great tension."I don't think that Americans, in general, want to hurt each other," Kempel said. "So the fact that somebody's very upset, and is shouting, even is getting too close to somebody else's nose, and is being very vocal, that does not mean that he or she wants to hurt their counterpart.""Which means for all of us," he continued, "if we manage our egos, and we manage our emotions, there will not be violence."Dr. Steven Stosny is a psychologist who specializes in emotional issues and couples therapy. He coined the term election stress disorder, or ESD, and said that people in our region are experiencing it strongly.To counter it, said Stosny, "The most important thing you can do is connect with your family, your friends, people you love, even if you have to do it by Zoom.""If you're living with someone whom you love, hug that person six times a day," Stosny said. "That gives you a hormone that naturally regulates anxiety, makes you feel close, more trusting.""The second biggest thing," Stosny continued, "is exercise. That's the great reliever of stress. Walking 30 minutes a day has been shown to be as effective for many people as anti-anxiety agents and antidepressants, with none of the side effects, and lots of benefits."This story was reported by James Ford at WPIX in New York, New York. 4742
