With the rise of smartphone dating applications, a phenomenon known as catfishing has become an issue for those looking to meet people online. In one Australian state, it could become a serious crime. According to 226

(AP) - There was a loud bang, and suddenly the Southwest Airlines jet rolled sharply to the left. Smoke began to fill the cabin, and flight attendants rushed row by row to make sure all passengers could get oxygen from their masks.When flight attendant Rachel Fernheimer got to row 14, she saw a woman strapped in her lap belt but with her head, torso and arm hanging out a broken window.Fernheimer grabbed one of the woman's legs while flight attendant Seanique Mallory grabbed her lower body. They described being unable to bring the woman back in the plane until two male passengers stepped in to help.The harrowing details from the April 17 fatal flight were released for the first time as the National Transportation Safety Board began a hearing Wednesday into the engine failure on Southwest Flight 1380, which carried 144 passengers and five crew members.The flight attendants told investigators at least one of the male passengers put his arm out of the window and wrapped it around the woman's shoulder to help pull her back in. Fernheimer said when she looked out the window, she could see that one of the plane's engines was shattered, and there was blood on the outside of the aircraft.Flight attendants asked for medical volunteers. A paramedic laid the woman across a row of seats and began chest compressions. They tried a defibrillator but it indicated that there was no shock. The paramedic and a nurse took turns at CPR.Passengers asked if they were going to die. Fernheimer said she squeezed their hands. "She told them that they were going to make it," an investigator wrote.Pilots Tammie Jo Shults and Darren Ellisor landed the crippled Boeing 737 in Philadelphia. The passenger in the window seat, Jennifer Riordan, was fatally injured — the first death on a U.S. airline flight since 2009. Eight other passengers including at least one of the men who helped pull Riordan back in the window.Wednesday's hearing in Washington focused on design and inspection of fan blades on the engine, made by CFM International, a joint venture of General Electric and France's Safran S.A.An official from CFM defended the design and testing of fan blades like the one that snapped on the Southwest plane as it flew high above Pennsylvania, triggering an engine breakup that flung debris like shrapnel into the plane.After the fatal accident, CFM recommended the use of frequent and more sophisticated tests using ultrasound or electrical currents.Another Southwest jet had suffered a similar blade-related engine breakup in 2016 over Florida.CFM and federal regulators considered the Florida incident an aberration."We determined early that we would require some corrective action in that it was an unsafe condition," an FAA expert on engines, Christopher Spinney, testified on Wednesday, "but we also determined we had some time."Rather than order immediate inspections of fan blades after the 2016 incident, the FAA began a slower process for drafting a regulation and getting public comment before enacting it. That process was still underway when the fatal accident occurred nearly two years later.Since the deadly flight, widespread inspections have turned up eight other fan blades on similar CFM engines that also had cracks. The fan blade that broke was last inspected six years earlier and, it was determined, suffered from metal fatigue even then — but it went unnoticed by a less sophisticated exam used at the time.Fan blades have been thought to have no real lifetime limit. CFM and FAA officials said they were now considering whether blades must be replaced at some point even if they don't show wear.Representatives from CFM also testified about testing and certification of jet engines, which are supposed to be built to prevent pieces from breaking off and flying free.The investigation is continuing. Most of Wednesday's hearing was highly technical. It was led by one of the safety board's five members, Bella Dinh-Zarr. The full board is expected to determine a probable cause for the accident in the next several months.Meanwhile, Riordan's husband, Michael, said in a statement on behalf of his family that they were "grateful for the heroic actions of the passengers who tried to save Jennifer's life.""The most important thing now is making sure that the aircraft and engine failures that caused Jennifer's untimely and unnecessary death never happen again," he said. 4408

 Two 250,000-year-old teeth from two Neanderthal children revealed that both of them were exposed to lead twice during their short lifetimes, the first known case of lead exposure in Neanderthals.An international team of researchers studied the two teeth, as well as one from a modern human child who lived 5,000 years ago. All of them are from the same archaeological site in southeast France. The results of their analysis were published Wednesday in the journal Science Advances."Traditionally, people thought lead exposure occurred in populations only after industrialization, but these results show it happened prehistorically, before lead had been widely released into the environment," said Christine Austin, study co-author and assistant professor in the Department of Environmental Medicine and Public Health at the Icahn School of Medicine at Mount Sinai. "Our team plans to analyze more teeth from our ancestors and investigate how lead exposures may have affected their health and how that may relate to how our bodies respond to lead today."And as with tree rings, researchers used the teeth to determine key events in the children's lives. During childhood, new teeth layers are formed each day, capturing chemical signatures that can be traced."Teeth record environmental variation based on the climate, even where you're growing up," said Tanya Smith, lead author of the study and associate professor at Griffith University. "That's possible because when you're growing, your teeth you actually lock in a record of the chemistry of the water and the food that you're eating and drinking. Because teeth have these tiny timelines, we can relate the chemistry to the growth to calculate ancient climate records. We can't do that with any other element of the body."They were able to determine that one of the Neanderthal children was born in the spring and that both children were more likely to be sick during the colder winter seasons. They lived through more extreme seasons with a greater variation in temperature than the modern human child who was also studied.The intact teeth had growth rings, which the researchers used to measure barium, lead and oxygen. Lasers targeted tiny spots in the teeth to map their chemistry and reconstruct ancient climate records. This reconstruction was able to map a weekly scale of variation, showing when the summer and winter seasons happened and how long they lasted. The researchers related this back to the individual's growth."This study reports a major breakthrough in the reconstruction of ancient climates, a significant factor in human evolution, as temperature and precipitation cycles influenced the landscapes and food resources our ancestors relied on," Smith said.The growth rings also provided evidence of nursing."We were able to identify milk intake through breastfeeding in one individual based on a trace element called barium," Smith said. "We were able to time that to the season."That individual nursed for 2? years, which is similar to modern human children who lived in hunter-gatherer environments. "This is something we may share in common with Neanderthals," Smith said. Unfortunately, although the Neanderthal child survived infancy, it did not reach adulthood. The ages of the children were not included in the study.The researchers believe that the children were exposed to lead environmentally, either inhaling or ingesting it."That must have come from natural deposits in the area, whether they were going into an underground environment or they were eating contaminated food that was incorporated into their growing bones and teeth," Smith said.Smith believes that this research emphasizes the different levels of information that can be taken from teeth."We've now got the ability to integrate ancient climate data with health history, nursing history and illness," she said. "To be able to get all that information from a single sample 250,000 years ago is a unique opportunity."But this doesn't just apply to studying those who lived before us."Dietary patterns in our early life have far-reaching consequences for our health, and by understanding how breastfeeding evolved, we can help guide the current population on what is good breastfeeding practice," said Manish Arora, study co-author and vice chairman of the Department of Environmental Medicine and Public Health at the Icahn School of Medicine. "Our research team is working on applying these techniques in contemporary populations to study how breastfeeding alters health trajectories including those of neurodevelopment, cardiac health and other high-priority health outcomes." 4648

 Willie Mays once said that no one could hit a baseball further than Willie McCovey. That is high praise from the former MLB Home Run King. On Wednesday, McCovey died peacefully at his home at the age of 80, the San Francisco Giants announced. McCovey was the 11th player in MLB history to join the 500 Home Run Club, and the second member of the Giants to join the club following Mays. McCovey hit 521 home runs in his 21-year career, which ended in 1980. In 1986, McCovey was inducted to the Baseball Hall of Fame after being selected on his first ballot. "Baseball has lost a giant, in every sense of the word, with Willie McCovey's passing this afternoon," Hall of Fame President Jeff Idelson said in a statement. "There wasn't a batter more feared by opposing pitchers than Willie Mac, who hit 521 mammoth home runs during a dominating 22-year career that included 19 seasons in a Giants uniform." 945

You see the spellers on the stage at Scripps National Spelling Bee, but there’s a critical player in the competition who you hear more than see.Dr. Jacques Bailly is the Bee’s official pronouncer, and to the spellers, he’s a celebrity. Participants lined up to meet the man many saw in the movie, Akeelah and the Bee, and who records the words many of them have studied.“It's really kind of an honor that they all come here, and they think I’m, you know, somebody famous and interesting to meet,” says Dr. Bailly. “We're here to honor them.”Dr. Bailly has a keen understanding of what the spellers are going through.He won the Bee in 1980 and has some tips for spellers taking the stage.“The way to spell a word you don't know: you spell it the way it sounds,” he advises. “Don't make a fancy guess. Don't assume there's a silent ‘Q’ because there aren't very many of those you know just felt the way it sounds. That's kind of the best guess.”His advice for beating the jitters?“I think a deep breath is one of the best things,” he says. “It's just, you know, to feel free, to get up there and go. Because it's amazing how that helps.”He believes competing in the National Spelling Bee opens doors for spellers to worlds they’ve never seen before at a critical age.“Doors to chemistry, doors to concert instruments, doors to culture of any sort,” he says. “It's the words that describe our world.”Dr. Bailly finds satisfaction in spelling, as well as sharing his passion with the next generation.“I just love doing this,” he says. 1542
