This is the first time that we have identified the detailed structure of the telomerase component from plants, said co-author Dr. Julian Chen, a professor of biochemistry at Arizona State University. The study was published Monday in the Proceedings of the National Academy of Sciences journal.Telomerase is the enzyme that creates the DNA of telomeres, the compound structures located at the tips of our chromosomes. Telomeres protect our cells from aging as they multiply."So in terms of fundamental research, this is a really big breakthrough because now finally we have a way to study telomerase in plants and to understand how different or similar they are from animals," Chen said.Could the discovery possibly lead to humans one day living as long as the fabled "Methuselah" tree, a bristlecone pine species that can live over 5,000 years? Maybe one day."This is really basic research. The application to humans is really a long way away," Chen said.In the meantime, however, experts like 995

This was just one of the many reasons Claire Golden and her family made the trip from Boston. “It’s really pretty,” Golden said. But lately, the neighborhood has become inundated with clumps of these bikes.“There is a bike war in San Diego, going on between five different companies,” Limandri said. On nearly every corner of Little Italy, there is a dockless bike. The bikes are a great amenity for people like Golden, who want to explore San Diego.“It’s easy...instead of getting an Uber or walking, to just get around the city,” Golden said.  However, the Little Italy Association says there are just too many of them in the neighborhood. So many that it's becoming a safety issue - especially when the bikes block sidewalks, parking spaces, ramps, and construction zones. Here's what they're going to do about it: “First thing in the morning, our maintenance guys come up with one of their trucks," said Marco Limandri of the Little Italy Association. "They’ll see if there are any of those bikes are blocking the sidewalks, and they’ll pick them up and they’ll relocate them two blocks away.The destination: State Street, which runs parallel to I-5. A location that the association says is far enough away from the hustle and bustle of restaurants and businesses in Little Italy. On any given day, you can see rows of endless bikes and scooters, sent to State Street from areas on India and Kettner Streets.  The Association said they do not necessarily have a problem with where the customers leave the bikes. They said most of them courteously park them on side streets. Instead, they took issue with where the bike companies launch them. “Our streets are not showrooms,” Limandri said. “These aren’t their sidewalks. They have no authority to place them. That’s the point.”The Association is in the early stages of proposing to each bike company, to take one parking spot as a designated launching lot. They have not reached an agreement yet, but they hope to get there soon. “This is a community in which pedestrians, bikes, cars, wheelchairs and strollers all have to interact,” Limandri said. “So once they understand that, I think we can work out an agreement where they are able to support the 'bikability' of San Diego, and people can come to Little Italy or other areas, and enjoy them.”Other San Diego neighborhoods dealing with similar issues include the Gaslamp and Hillcrest. They hope to come to a compromise through the implementation of permits.  2548

Three United flights were canceled, seven others were diverted and 15 more were delayed, officials said."During the outage, Los Angeles Airport Police deployed traffic officers to the (Central Terminal Area) and surrounding streets to assist with traffic flow," the airport said. Officers were also assigned to the ticketing areas to help with crowd management and provide directions for passengers, as well as maintain security at Transportation Security Administration checkpoints. 483

This is a very, very hostile act, he said. "We have been extending our hand to Iran since 1979 in friendship, and what we get back is death and destruction." 157

This follows statues being torn down in cities across the country.The Federation of Italian-American Societies of Western New York says the statue will not be destroyed, and are looking at several places to put the statue. 222
