iStock/Thinkstock(MIAMI) — The apparent alligator attack that resulted in the death of a Florida woman who was walking her dogs near a lake is an extremely rare occurrence, authorities said.An estimated 5 million American gators live in the southeastern United States — about one-quarter of them in Florida alone — but the likelihood of being seriously hurt from an “unprovoked alligator incident in Florida is roughly only one in 3.2 million,” according to 2017 statistics from the Florida Fish and Wildlife Conservation Commission.“Over the last 10 years, Florida has averaged six unprovoked bites per year that are serious enough to require professional medical treatment.”Summer is mating season, which can mean more active and territorial alligators, according to experts. Shizuka Matsuki had disappeared Friday in Davie, Florida, before her dogs were found wandering alone, one badly injured, officials said.Authorities later found Matsuki’s body and captured and killed an alligator measuring 12 feet 6 inches in length. When the Florida Fish and Wildlife Conservation Commission performed a necropsy on the reptile, they found Matsuki’s arm, identified by a tattoo, in the gator’s stomach, officials said. How to stay safeTo avoid an encounter with a gator, wildlife experts said, people must never feed them. It’s not only dangerous but also illegal in Florida.Families with young children should also steer clear of waterways at nighttime, when alligators can’t decipher the difference between a child and its normal food sources, which include birds, rodents and other small mammals.People must be especially vigilant during nesting season, in June and July. “It’s rare that an alligator will come out of the water and go after a human being,” Ron Magill, a wildlife expert and communications director at Zoo Miami, told “Good Morning America” in 2016. “They usually nest close to the water. If you get near a nest, a female will come after you. Females are very protective.”In the unusual event that you find yourself squaring off with a gator, wildlife experts offer these four tips:RunIf you happen to lock eyes with an alligator on land, forget running in a zigzag. Run away as fast as you can in a straight line. Alligators will typically chase a human only to defend their territory.“The longer you stay within their territory, the longer they’re going to chase you,” Frank Mazziotti, a professor of wildlife ecology at the University of Florida’s Fort Lauderdale Research and Education Center, told ABC News in 2016. “When you run back and forth, you are in fact exposing yourself to attack for a longer period of time than if you just ran in a straight direction and got out of there. Once you’re no longer a threat, it has no interest in you.” Fight backIf a gator grabs hold of you, there are a few things you can do. Most important, don’t give up.“Fight like hell. Don’t go willingly,” Mazziotti said. “The bigger fight you put up, the more likely it’s going to let you go and say, ‘This isn’t worth it.’”Smack the snoutRather than try to open a gator’s jaws, which are extremely powerful, aim for where the animal is most vulnerable, like its snout.“Pop them on the snout. The tip of their snout is very sensitive. That might be able to get them to release you,” Magill said.Gouge the eyesJabbing a gator in the eyes may also make it release its bite, even for just a moment, allowing you to get away before it pulls you underwater.“The thing you want to stop them from doing is turning. They’ll grab, and they’ll start rolling to try to break off pieces to eat, and that’s the key thing,” Magill said on “GMA.” “You’ve got to hold on as hard as you can. And the other is to try to poke your fingers in their eyes. That’s easier said than done in that situation, of course, but that’s the best chance you have.”Copyright © 2018, ABC Radio.

Reduce. Reuse. Recycle. We hear this mantra time and again. When it comes to carbon — the “Most Wanted” element in terms of climate change — nature has got reuse and recycle covered. However, it’s up to us to reduce. Scientists at Harvard Medical School are trying to meet this challenge by learning more about the carbon cycle, that is, the process by which carbon moves from the atmosphere into plants, oceans, soils, the Earth’s crust, and back into the atmosphere again.One of the biggest movers and shakers is the lowly cyanobacteria, an ocean-dwelling, one-celled organism. Pamela Silver, HMS professor of systems biology, and colleagues have uncovered details about how this bacteria fixes, or digests, carbon. These bacteria build miniature factories insidethemselves that turn carbon into fuel.Silver and her colleagues report online in the journal Science that the bacteria organize these factories spatially, revealing a structural sophistication not often seen in single-celled organisms. This regular and predictable spacing improves the efficiency of carbon processing. In the future, an understanding of the mechanisms that govern this spatial organization may help improve the efficiency of designer bacteria engineered to produce carbon-neutral fuels such as biodiesel and hydrogen.The rod-shaped cyanobacteria are among the most abundant organisms on earth. Forty percent of the carbon in the carbon cycle is reused and recycled through these tiny creatures. To process carbon, cyanobacteria build soccer-ball-shaped structures inside themselves called carboxysomes. These tiny factories absorb carbon dioxide and convert it into sugar, which the bacteria then use to produce energy.“The ocean is just packed with these bacteria. By studying them, we’re understanding more about how the earth works,” said Silver, who is also on the faculty of the Wyss Institute for Biologically Inspired Engineering at HMS. “I’m blown away by what’s happening in the ocean and what we don’tunderstand about it. There are a lot of things in the ocean that are going to be useful to us.”The research team, led by co-first authors, research fellows David Savage and Bruno Afonso, attached a fluorescent tag to proteins involved in building the carboxysome, then grew the tagged bacteria under a microscope.The resulting images revealed that, instead of being randomly numbered and haphazardly placed, cyanobacteria build carboxysomes in numbers that scale with their size, and they space the factories evenly along their length.The finding adds evidence for new ways to think about bacteria. “We had this idea of bacteria as a bag of enzymes, but that has been completely shattered,” said Afonso.A single protein, called parA, acts as a kind of inner-bacterium stage manager, arranging the carboxysomes in a neat, single-file row, the researchers found. When they disabled the bacteria’s ability to make the protein, the carboxysomes were distributed far more randomly.The cyanobacteria lacking parA were also less “fit” for survival, said Savage. While wild-type bacteria cells have a consistent number of carboxysomes, which in turn optimizes carbon processing and fitness, the knockout bacterium created daughter cells whose numbers of carboxysomes ranged from none to an excess. The daughter cells with few or no carboxysomes divide more slowly and also process fifty percent less carbon than daughter cells at the other end of the spectrum. (see video 1)By tagging parA in wild-type bacteria, they discovered interesting dynamics in the protein. Thousands of parA proteins repeatedly cluster together and shoot quickly from one end of the bacterium to the other.“It’s amazing that you can generate this regularity and symmetry potentially from a single protein,” said Savage. “It’s amazing that it is somehow tuned by the dynamics of the protein.” The researchers have not yet identified the exact mechanism parA uses to govern the spacing.Many other bacteria also have the parA protein, which is known for separating chromosomes during cell division. “This work highlights how bacteria cobble together spare parts to achieve similar goals such as organization and segregation,” said David Rudner, HMS assistant professor of microbiology and molecular genetics, who was not involved in the study.These findings may help synthetic biologists one day create designer bacteria.“Knowledge about how cells create and deploy specialized factories like the carboxysome opens the way to creating other kinds of mini factories that could perform useful functions,” said Richard Losick, Harvard University professor of molecular and cellular biology, who was not involved in the study.Silver’s lab is looking into whether the carboxysome might be useful for optimizing the production of hydrogen by engineered bacteria. One challenge in designing hydrogen-producing bacteria is that the enzymes that produce hydrogen are sensitive to oxygen. The carboxysome may help solve thisproblem because its outer shell blocks out oxygen, protecting the enzymes inside from its toxic effects.This research was funded by the US Army Research Office.

Press Trust Of India Written By COMMENT The Sports Authority of India (SAI) on Friday said it will arrange for the boarding and lodging of top recurve archers of the country who are currently in Pune to compete at the selection trials for the Tokyo Olympic Qualifiers starting on Saturday. “The government will provide support as has been done for the national campers for the boarding and lodging of the men’s and women’s recurve archers competing at the trials in the Army Sports Institute (ASI),” the Sports Authority of India (SAI) said in a statement. The Sports Ministry’s decision came after some reports claimed that Olympians like Deepika Kumari, Bombayla Devi and Atanu Das were left to fend for themselves after arriving in Pune for the selection trials.READ | MLB Trade Rumours: 5 Best Remaining Free Agents Who Are Likely To Fetch Big BucksREAD | Unbeaten Auburn Visits Mississippi St. To Open SEC ScheduleSAI says it will take care of archers’ boarding and lodgingAs per the reports, the archers were left to arrange for their own boarding and lodging after arriving in Pune since SAI has made no such arrangement in the absence of a suspended Archery Association of India. Deepika, Bombayla, Atanu and 21 other archers have been exempted from stage 2 trials as they were part of the stage 1 open trials held in August last year. They will be competing in stage 3 to be held from January 18 to 22. They were also part of the national camp for the Asian Archery Championships held in Bangkok from November 21 to 28. Stage 2 of the open trails will be held from January 4 to 7.

DES MOINES — Officials in Iowa’s largest school district are adding two more days onto this month’s break for students and will have school facilities thoroughly cleaned due to concerns about the coronavirus. Des Moines Public Schools Superintendent Thomas Ahart says there are no known cases of COVID-19 among staff or students.“We think we’re being very proactive as opposed to being in a panic situation,” Ahart says. “Once we have identified cases in our schools, it’s really too late to do meaningful mitigation.”Students were already scheduled to be off through March 26th for next week’s spring break, followed by teacher-only training days and conferences. Teachers will do that work online. Ahart says the district’s buildings will undergo a deep cleaning as students and staff are absent.“We know that with 5000 staff and about 33,000 students, we impact every community in the greater metro area and so it’s incumbent upon us to do what we can to stem the tide,” Ahart says.Classes will be held in Des Moines Public Schools today. After a 17-day break, classes are now scheduled to resume March 30th.
