A bacteria that was thought to have existed a century ago, but could never be found, has finally been discovered.California Institute of Technology (Caltech) microbiologists Jared Leadbetter and Hang Yuat, who discovered it, said in a press release that the bacteria feeds on manganese and uses the metal as their fuel source."This discovery from Jared and Hang fills a major intellectual gap in our understanding of Earth's elemental cycles, and adds to the diverse ways in which manganese, an abstruse but common transition metal, has shaped the evolution of life on our planet," said Woodward Fischer, professor of geobiology at Caltech, who was not involved with the study, in the news release.The study showed that the bacteria can use manganese to convert carbon dioxide into biomass, a process the scientists called chemosynthesis.The discovery came after an accidental and unrelated experiment with a chalk-like form of manganese, the scientists said.The research was published in the journal Nature on Tuesday.NASA and Caltech funded the study. 1061

(KGTV) - Suspected drug smugglers were rescued by U.S. Coast Guard crews this month after their vessel erupted into flames before sinking.Crews from the Coast Guard, Customs and Border Protection Air and Marine Operations (AMO), the U.S. Navy ship USS Zephyr, and the Colombian Navy ship ARC "07 de Agosto" detected the high-speed vessel on April 7 in the eastern Pacific Ocean.As crews prepared to intercept the vessel, the suspected smugglers allegedly began abandoning their cargo and jumped from the boat as it caught fire.RELATED: Canadian who posted drug smuggling trip on Instagram sentenced to prisonCrews rescued four suspected smugglers and spent 90 minutes extinguishing the flames."There was no doubt in our minds what needed to be done to salvage the evidence needed for a successful prosecution even if it meant laying Zephyr alongside a burning hull, with the intense heat and acrid smoke hindering our 90-minute firefight," Lt. Cmdr. Grant Greenwell, the commanding officer of the Zephyr, said.After putting out the fire, crews say they recovered about 1,080 pounds of cocaine. The four suspected smugglers were transferred to custody aboard the Zephyr.The suspected drug vessel was severely damaged and sunk as it was a hazard to navigation. 1281

A 2-month-old in Arizona has tested positive for COVID-19, according to her mother.Angelica Wendell of Gilbert thinks her newborn Eevee contracted the virus from Wendell's sister, who was at their home visiting recently and later developed symptoms. She was shocked to find out her daughter had the virus."Everyone's like kids don't get it, so it's not a big deal, it's just old and sick people. So when you find out your newborn has it, she's my first kid, so I've never had another baby to experience any other illness with, so when you find out it's COVID, it's just heartbreaking. I started panicking because I didn't know what was going to happen," said Wendell.Wendell said Eevee first developed a fever and stopped acting like her happy self."I had a bad feeling about it so I took her to the emergency room. The next day she started getting bad congestion and she started getting a viral rash."Wendell said Eevee is now doing a lot better. She's fever-free and she's eating again.Dr. Eunice Yoon, a critical care pediatrician at Banner's Cardon Children's Medical Center, said it's hard to know for sure how common the virus is in infants."We know that kids overall are maybe 5-10 percent of all the positive tests that we have. But we're also not testing everyone, so it's hard for us to know. We also know that babies primarily are getting their infections from adults. They're not getting them from other kids."She said babies and children with the virus usually have mild symptoms, and up to 50 percent of children don't show symptoms at all.Dr. Yoon recommends adults do their part -- keep a distance, wash hands and wear masks, especially around infants."We're always worried about those newborn babies when they're less than a month; their immune systems are not fully developed. We don't know whether this viral illness could predispose them to other illnesses, and we don't know if there's going to be any effects down the road for these kids," said Dr. Yoon.Wendell hopes others learn from her story and take precautions."Just be careful, even if you don't let your baby outside be careful who you let around them because you think even your family is fine, but you may not know exactly what they're doing. It's very sad to watch your child, especially with this disease that no one really knows a whole lot about," said Wendell.Wendell has had a fever but doesn't have severe symptoms. She got tested for the virus but hasn't gotten results back yet.KNXV's Claudia Rupcich was first to report. 2520

“Ask Brianna” is a column from NerdWallet for 20-somethings or anyone else starting out. I’m here to help you manage your money, find a job and pay off student loans — all the real-world stuff no one taught us how to do in college. Send your questions about postgrad life to askbrianna@nerdwallet.com.Sure, your college may allow students to pay for tuition and fees with a credit card. But, like partying the night before a midterm, it’s probably not a good idea.Paying for anything with plastic requires a plan to get rid of your balance fast. That keeps interest charges from piling up. Plus, many schools charge “convenience fees” that could cost more than the value of any rewards points or cash-back bonuses you’re hoping to get on your card.Here’s what to weigh before using one type of credit to pursue another. 827
