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 deeply divided political climate, Washington witnessed a rare moment of unity on Monday as lawmakers from both sides of the aisle came together to remember George H.W. Bush.The Republican former President died on Friday at the age of 94. On Monday, his body was brought to the US Capitol rotunda where Bush will lie in state until Wednesday morning, an honor reserved for government officials and military officers.Democrats and Republicans remain locked in a standoff over funding for President Donald Trump's border wall that could trigger a partial government shutdown in the coming days and Washington is still reeling from a divisive midterm campaign season where the leaders of both parties were targets and Trump frequently went on the attack on the campaign trail.But for at least a few hours, the two parties appeared to put their political differences aside.As crowds began to gather outside, a ceremony was held inside the rotunda where Capitol Hill's highest-ranking Republican and Democratic lawmakers joined together in paying tribute to the former President.Senate Majority Leader Mitch McConnell and Senate Minority Leader Chuck Schumer stood side-by-side as a wreath was placed alongside the casket. In another image of unity, House Speaker Paul Ryan and House Democratic Leader Nancy Pelosi did the same several minutes later, standing next to one another as a second wreath was placed.Pelosi, who is vying to become House speaker when Democrats take control of the House of Representatives in the new Congress, stood next to Kevin McCarthy, who will serve as the House Republican leader in the next Congress, as lawmakers filed in at the start of the event and the two could be seen speaking to one another.Earlier in the day, McConnell and Schumer both gave speeches on the Senate floor praising the former President."He embodied the characteristics we admire in a president: integrity, civility, dignity, humility," Schumer said during his speech. The Senate Democratic leader added, "I knew him to be a fine man. A decent man. And even when he opposed your views, you knew he was doing what he thought was best for the United States of America."A long list of prominent current and former officials gathered inside the rotunda to pay their respects.Vice President Mike Pence delivered a speech. Prominent former lawmakers, including former Senate Majority Leader Republican Bill Frist, were seen at the Capitol as were sitting Supreme Court justices, including Clarence Thomas, who was nominated to the bench by Bush.Outside the Capitol, a long line of people waiting to pay their respects to the 41st President began to form early in the evening. Starting at around 7:30 p.m. ET on Monday, members of the public began to be allowed into the rotunda to view the casket.Joe McGarvey, a 62-year old Democrat, was one of the people who waited in line to pay his respects to what he described as "a man who gave a life of service to the country.""I'm a Democrat, but as President, he did a lot of good things," McGarvey said during a brief interview. He described Bush as a "very humble, caring person -- you could tell, just how he treated people."As McGarvey waited, the temperature began to drop. "It's getting a little cold here," he said, "even though I'm standing out here in the cold, I'm glad I did it."Stephen Keblish and Nate Crossett from Utica, New York said they had driven down to Washington, DC that morning.Keblish described it as a "once in a lifetime kind of opportunity.""It's a sort of pilgrimage in a way. There aren't a lot of opportunities for ritual in this day and age especially as a country so I wanted to partake in something like that," he added.Christine Dube, who lives in Vermont, but travels to DC periodically for work, said she believes Bush was from an era where people did "the right thing and you care about America and that comes first.""I think maybe people need to start thinking about that a bit more," she said, "following that set of values, not fighting with each other, agreeing to disagree, doing what we're supposed to do, take care of each other ... not be at odds with each other all the time.""Our country needs to come together," Dube said, adding, "Regardless of what your political views are, I think everybody at heart wants to see our country do well."Among those also paying respect Monday evening: the President and first lady Melania Trump, who stood in front of Bush's casket in the Rotunda at around 8:30 p.m. ET. 4520

Hundreds of museums across the country are struggling financially. Many were shut down for long periods of time during stay-at-home orders to slow the spread of the coronavirus. Some are still not ready to reopen. "We're targeting to reopen next year. Hopefully, we will sit back and recover and be able to think through and make sure everything will be safe for everybody," said Lily Birmingham, the director of the San Diego Chinese Historical Museum. Birmingham's museum, like many others, shut down in March because of shelter-in-place restrictions."We have very little funding to begin with so with the closure of the museum, we can not raise funding. We couldn't get admission funding so we had to lay off our employees. We now rely on volunteers, so it's very difficult. Funding is always difficult for museums. We're a non-profit organization," said Birmingham.Recently, The American Alliance of Museums surveyed more than 750 museums nationwide. From large to small and in urban and rural communities. What they found was that nearly one-third of them may not survive this pandemic."Back in March, I kind of speculated that it might be 25-30% of museums that would not make it through an extended financial crisis and indeed the survey did confirm our worst fears that one in three museums say there is a significant risk for having to close permanently," said Laura Lott, the President and CEO of the American Alliance of Museums. Lott says most museums make the majority of their money from ticket sales, renting their space for events and sales from their gift shops and cafes. Lott says museums have three major impacts on their communities, the first is economic."Museums contribute more to the economy than we might imagine. Nationally it's about billion that museums contribute to the national GDP across the country. They employ 750,000 people and pay billion in tax revenue at the state, federal and local level, even though most are non-profits," explained Lott.The second impact is on education, as they host numerous schools for field trips. Lott says the third impact museums have is they protect our cultural heritage. "Each museum is unique. It holds unique artifacts and stories that we’ve chosen to preserve and protect for future generations and if those museums go away, they're likely to be gone forever," said Lott.For the San Diego Chinese Historical Museum, historians have been collecting items dating back more than 100 years, preserving history of when Chinese immigrants first came to California. "There's a couple things people can do to help museums right now. People need to really contact their legislators and let them know why their museums are important to them and advocate that museums be included in any financial relief at all levels; the federal, state and local levels," said Lott."It could be monetary, of course, is the best. Volunteer hours or just show the appreciation. Show the concern and care so we know people love our museum. So, there are different ways to show the appreciation," said Birmingham. Lott says any bit of support will make a difference for many museums so they can continue to preserve history for years to come. 3202

In a resounding defeat after months of negotiations, senators on Thursday failed to advance a bipartisan proposal to resolve the future of millions of young undocumented immigrants, leaving talks seemingly back at square one.A much-anticipated bipartisan deal that would have paired a pathway to citizenship for nearly 2 million undocumented immigrants who came to the US as children with billion in border security and some other measures failed to get the 60 votes necessary to advance legislation after furious White House opposition.The vote was 54-45.A competing White House-backed plan that would have also substantially increased federal deportation powers, heavily cut family-based legal migration and end the diversity visa also failed, 39-60.The episode, coming at the end of a much-anticipated Senate week of debate on immigration, revealed that the White House was successfully able to kill momentum for a deal that had emerged out of weeks of talks by roughly 20 bipartisan senators -- but that it also had no ability to actually enact any legislation to achieve its stated goal of protecting the recipients of the DACA program that President Donald Trump is ending and enact border security measures with it.Trump called the bipartisan bill "a total catastrophe," tweeting that "Voting for this amendment would be a vote AGAINST law enforcement, and a vote FOR open borders."Attorney General Jeff Sessions also derided the legislation, saying it "will invite a mad rush of illegality across our borders," and Homeland Security Secretary Kirstjen Nielsen made calls to lawmakers urging them to reject the bill.And Sen. Tom Cotton, an Arkansas Republican, said on the Senate floor that the plan would be called the "olley olley oxen free amendment."The legislation from a group of 16 bipartisan senators would offer nearly 2 million young undocumented immigrants who came to the US as children before 2012 -- like those protected under the Deferred Action for Childhood Arrivals program -- a path to citizenship over 10 to 12 years.The plan would also place billion in a guarded trust for border security, would cut a small number of green cards each year for adult children of current green card holders, and would prevent parents from being sponsored for citizenship by their US citizen children if that child gained citizenship through the pathway created in the bill or if they brought the child to the US illegally. Senators peeved at White House 2484
