Scientists from all over the world recently returned home after the largest Arctic expedition to date.The Polarstern, a German ice breaker, housed hundreds of scientists who spent time over the past year to do research in the Arctic.“The MOSAiC Expedition is an expedition to the central Arctic. We took a ship, an icebreaker ship, and froze it in the arctic sea ice. It stayed there and drifted with that ice for a full year and that ship served as a platform for doing all kinds of research to understand the changing Arctic sea ice and the implications that has on the arctic system and global system,” Matthew Shupe, scientist and co-coordinator of the MOSAiC Expedition, said. He is also a professor at the University of Colorado Boulder.“MOSAiC really represents the largest expedition to the arctic ever,” he said. “MOSAiC is, I would say, very photogenic. It’s really compelling and captivating to all kinds of audiences.”But the data collected and changed observed during the rip serve a larger purpose than just beautiful, picturesque nature videos and photos.“The Arctic is changing. The sea ice is changing and we knew this,” Shupe said. “But when we went there the ice was thinner than we expected.”That change impacts a number of things. Shupe said as the Arctic changes, it’s opening for business. “It’s opening for cargo transportation, it’s opening for tourism.”It’s an indicator of larger changes as well.“Can potentially affect our weather, you can imagine the large scale circulation of our globe is dependent on things like a cold North Pole versus warm tropics and that affects the large scale circulation,” he said.The data these scientists collected over the span of a year will be used for global climate and weather prediction models.“These models rely on information, we have to understand the Earth's system in order to model it,” Shupe said.Hundreds of scientists from 37 different nations, all focusing on different projects, funded in part by U.S. tax dollars.“This is funded by the national science foundation, department of energy, NOAA, NASA, these are institutions that are funding this kind of research to understand arctic change and how it affects all of us," Shupe said.Next year, you’ll be able to experience the Arctic, too.“This planetarium film is an educational documentary about the MOSAiC Expedition,” said Lianna Nixon, a filmmaker, who spent a few months aboard Polarstern. She documented the expedition for a few months to bring the Arctic to everyone. “What we wanted to do was really express what kinds of science people were doing in the field and take that into your local planetarium.”The 30-minute film will be available at planetariums as soon as next year -- a 2D version will also be available.“The Arctic impacts all of us no matter where we live. The polar regions drive a lot of our global climate systems,” Nixon said.Expeditions to the Arctic have been happening for more than 100 years, but this new data collected by MOSAiC will be used in the science community for years to come.“MOSAiC is building on this history of expeditions to the Arctic,” Shupe said. 3131

SAN MARCOS, Calif. (KGTV) — Palomar College announced Friday that the school's police academy will no longer train cadets on how to perform a carotid restraint hold.The restraint will not be taught or used in the academy setting, according to Palomar's Director of Public Safety Programs Michael Andrews.“Effective last week, the tactic is no longer being employed or used in the academy setting, period,” Andrews said. “We won’t even use it as an example. It will just simply be erased from training.”RELATED: San Diego County law enforcement agencies that have stopped using carotid restraintPalomar's decision comes after several agencies through San Diego County ended the use of the restraint technique amid demonstrations against police violence.On June 18, the California Commission on Peace Officer Standards and Training approved changes to its "Arrest and Control" learning unit to remove the training and use of the hold.Andrews adds that the school is in the process of changing its academy curriculum to align with the learning unit's changes.“Palomar took a stance, and we were successful,” Andrews said. “There are many other policing tactics which, when employed properly, can be productive. There is no need for this particular tactic.”He added that originally the restraint was to be a last resort tactic, but has gradually become a common move during arrests.Palomar Community College District Interim Superintendent and President Dr. Jack Kahn applauded the move, saying, "Palomar College is committed to training professionals, including police officers, who will serve and build up the community. We applaud the Commission, and our Police Academy leaders, for taking meaningful action on this issue." 1730

Saturday marks the 87th anniversary of the "Star-Spangled Banner" being named the national anthem — and the song hasn't seen this much controversy since being anointed the official song of the United States in 1931.On top of becoming a political platform for athletes and politicians alike, the anthem has seen some of its most unique performances in the past year — most notably, Fergie's controversial rendition at the 2018 NBA All Star game.But Fergie's version of the "Banner" is just one of many controversial renditions of the song. As it celebrates it's birthday as America's anthem, let's revisit a few more notable renditions.Jose Feliciano — 1968 World SeriesFeliciano was among the first artists to deviate from the traditional playing of the anthem — and he did it in front of a nationwide audience. With the country already divided by the Vietnam War, Feliciano's rendition outraged many. Newspaper reports called Feliciano's performance "disgraceful," and some called him a "hippie."Despite the controversy at the time, Feliciano was invited back to Detroit to sing the anthem 44 years later before a Tigers playoff game, where he received unanimous applause.Jimi Hendrix — Woodstock (1969)Prior to Hendrix's performance at Woodstock, it was hard to imagine the national anthem being played on an electric guitar. Now, it's considered one of the most iconic renditions of the anthem ever performed.Roseanne Barr — San Diego, 1990Comedienne Roseanne Barr is not known for her singing voice, and it showed during her rendition of the anthem prior to a baseball game between the San Diego Padres and the Cincinnati Reds. She screeched her way through the anthem, and capped it all off by spitting on the ground and grabbing at her crotch.Barr maintains her act was a joke, and told the Washington Post that she wasn't trying to respect the anthem or the flag with her performance. President George Bush disagreed.For her part, Barr maintains her version of the anthems was better than Fergie's.Whitney Houston — 1991 Super BowlWith the country newly entangled in a foreign war and security tensions high at the world's biggest sporting event, Houston delivered perhaps the most stirring and inspiring live performance of the anthem in the song's history. Even after her death, Houston's performance at the Super Bowl remains one of her most played songs.Jack Black — Los Angeles, 2011Black is most known for his slapstick comedy, so it must have been strange for fans of the WNBA's Los Angeles Sparks step to the mic for the anthem in 2011.However, Black is one half of the musical duo known as Tenacious D, and showed off his pipes in the 2003 comedy "School of Rock." Whether or not the Staples Center crowd was ready for it, Black went out and delivered a stirring rendition of the "Star Spangled Banner."Jesse McGuire — 2013 NFL PlayoffsThough the national anthem is played and sung live dozens of times each day, it's not often that an instrumental version of the anthem is played solo. McGuire, a renowned trumpeter, has played that anthem dozens of times at some of America's biggest sporting events, but his 2013 performance at a 2013 NFL playoff game between the Carolina Panthers and the San Francisco 49ers reminded viewers that sometimes, the anthem is at its best on a lone trumpet. Alex Hider is a writer for the E.W.
