Thirteen children of firefighters who died at the World Trade Center on September 11, 2001, and six whose fathers died of 9/11-related illnesses, graduated from the city's fire department during an emotional ceremony.They were part of a group of 301 probationary firefighters to graduate Tuesday after 18 weeks of intensive training at the New York City Fire Department academy."Many of their fathers were killed on September 11, several others died of World Trade Center illnesses, and others lost their lives in the course of their duty, bravely working to save and protect others," said Fire Commissioner Daniel Nigro, who presided over the ceremony."Today, these 21 legacies are no longer children dreaming of their careers their fathers loved, and of serving in the world's greatest fire department -- today, they have fully achieved their dreams."Firefighter Carl Asaro was one of the 343 FDNY members killed after the terror attacks on 9/11.His children, Rebecca and Marc Asaro, graduated on Tuesday."Every day that I came to the academy, I was grateful to be there and to follow in the footsteps of my father, brothers, uncle, and all those who came before. This is exactly where I want to be," said Rebecca Asaro.They have two siblings already on the job, Firefighters Matthew and Carl Asaro, Jr.Robert Tilearcio Jr. took the test the same month his father, Robert Tilearcio, died from 9/11-related cancer, he told 1436

This is the extraordinary tale of how a massive, strange-looking fish wound up on a beach on the other side of the world from where it lives.The seven-foot fish washed up at UC Santa Barbara's Coal Oil Point Reserve in Southern California last week. Researchers first thought it was a similar and more common species of sunfish -- until someone posted photos on a nature site and experts weighed in.What transpired after that surprised researchers from California to Australia and New Zealand.It turned out to be a species never seen before in North America. It's called the hoodwinker sunfish."When the clear pictures came through, I thought there was no doubt. This is totally a hoodwinker," said Marianne Nyegaard, a marine scientist who discovered the species in 2017. "I couldn't believe it. I nearly fell out of my chair."How the hoodwinker got its nameNyegaard spent years chasing the hoodwinker sunfish before she located and named the fish. All cases of the big fish were found in Australia, New Zealand, South Africa and Chile, she said. Except for one time in the 1890s, when drawings and records documented the fish appearing in the Netherlands.Scientists say there are five species of saltwater sunfish, and they come from different places. One enjoys tropical waters, another likes the subtropics and the hoodwinker prefers temperate water, Nyegaard told CNN. She works in the marine division at the Auckland War Memorial Museum in New Zealand."This is why it's so intriguing why it has turned up in California," she said. "We know it has the temperate distribution around here and off the coast of Chile, but then how did it cross the equator and turn up by you guys? It's intriguing what made this fish cross the equator."The antics of this wayward fish are comical, especially considering how the species got its name.As Nyegaard researched the fish, she realized some species of sunfish had been misidentified. One species that was thought to be rare was very common, while another fish thought to be common was misidentified, she said."It had gone unnoticed because no one really realized it looked different. There's a long history of confusion about the species in the sunfish family," Nyegaard said. "This fish had managed to stay out of sight and out of everybody's attention. It had been taken for mola mola (an ocean sunfish) so it was hoodwinking us all."And a bit of hoodwinking is what it was doing to researchers in California, too.Scientists first thought it was a different type of sunfishAn intern at Coal Oil Point Reserve alerted conservation specialist Jessica Nielsen to the dead beached sunfish on February 19. When Nielsen first saw it, the unusual features of the fish caught her eye."This is certainly the most remarkable organism I have seen wash up on the beach in my four years at the reserve," Nielsen said in a UC Santa Barbara press release.She posted some photos of the fish on the reserve's Facebook page. When colleague Thomas Turner saw the photos later that day, he rushed to the beach with his wife and young son.Turner, an evolutionary biologist who is six feet tall, stretched out his arms to show the scale of the seven-foot-long fish. He snapped some photos of what he thought was an ocean sunfish, a rare sight up-close, he said."It's the most unusual fish you've ever seen," said the UC Santa Barbara associate professor. "It has no tail. All of its teeth are fused, so it doesn't have any teeth. It's just got this big round opening for a mouth."Turner posted his photos on 3545

The Pentagon has ordered an additional 8,000 ventilators, with delivery of the first 1,400 by early May. The .4 million order was placed with several suppliers under existing Defense Logistics Agency contracts.A Pentagon spokesman, Air Force Lt. Col. Michael Andrews, identified the four suppliers as Zoll, Combat Medical, Hamilton Medical, and VyAire. Andrews said delivery locations will be prioritized by FEMA and the Department of Health and Human Services. These are in addition to the 2,000 ventilators that the Pentagon previously said it would make available to FEMA from Defense Department stockpiles. 625
