Beyond the beaches of the world, lies the potential for oceans of energy."I'm very excited about this because it's a very renewable energy-based technology,” said Professor Bruce Logan of Penn State University.Logan and university researchers recently created a device that removes salt from seawater in a cheaper way, allowing that water to then be used to create a renewable form of hydrogen fuel.“There's a lot of interest in renewable hydrogen,” Logan said. “Most of the hydrogen made today is made from fossil fuels, and so, we're interested in making that hydrogen from water.”That involves splitting water molecules into oxygen and hydrogen. The problem? Seawater also has salt, which needs to be removed first and that’s expensive to do.However, the “seawater electrolyzer” that Logan and his team worked on takes care of that issue cheaply by using a special membrane and without requiring expensive desalination plants. The findings were recently published in the Journal of Energy and Environmental Science.“Hydrogen is a great fuel,” he said. “It's been examined as a fuel for many decades now.”About 97 percent of all the water on earth is in the ocean, which means if it could be used efficiently to make hydrogen fuel, it could be a game-changer.“As we look to de-carbonize our fossil fuel infrastructure, we also can use it primarily for heavy-duty vehicles,” Logan said. “Airbus is looking to actually make airplanes that fly on hydrogen.”For now, though, their device would need to be scaled-up to a much larger version.“There are many nations and companies and nations across the world looking to do this. One of the biggest proposed hydrogen plants is in Saudi Arabia -- billion,” Logan said. “I would hope to convince them that it might be cheaper and better to use seawater directly, you know, in a system like this.”It’s a possibility that might one day create a bridge between our energy needs on land and the power in the sea. 1962

BONSALL, Calif. (KGTV) — Deputies are investigating a use of force incident Thursday after a suspect stopped breathing after being restrained for reportedly biting a deputy.San Diego Sheriff's deputies responded to a disturbance call at about 4:30 a.m. at the Circle K convenience store at Old Highway 395 and Highway 76.Upon arriving, deputies said they encountered a man behaving erratically. Deputies said they asked him several times to leave the property and he then swung at them, prompting an altercation.An SDSO detective said the suspect bit a deputy in the web of the hand, badly enough that the deputy has to get stitches.After biting the deputy, the man was placed in a full body restraint and loaded him into an ambulance, according to SDSO. No firearms were discharged.Officials say while the suspect was in paramedic's care, he stopped breathing. The man was stabilized once he reached the hospital.MAP: Track crime happening in your neighborhoodNo further update on the suspect's condition was given.SDSO said the deputy whose hand was bitten is being treated at a local hospital as well. 1157

BLOOMINGTON, Ind. -- Five people, including two elementary school students, were arrested after police investigated online threats made against another student. The Bloomington Police Department began investigating after a Fairview Elementary School representative notified police about a threatening Instagram video on Feb. 17. The video showed two students making threats and showing an AK-47-type weapon. One of the boys in the video made threats toward a female student and her brother. He said the gun was real and the two people were going to get "lit up," police say.In the investigation, police learned the threats were made after an argument about a dating relationship between the parties. Police then went to a house to locate the weapon in the video. At the house, a woman, Laquita S. Perry-Leverston, 33, went to the trunk of a car, where she retrieved the weapon and a pistol. Both were BB guns, police say. After a warrant was obtained, police began searching the house. One person in the house, a 17-year-old boy, told officers they weren't going to touch him, according to police. He began resisting and was arrested by officers. The 17-year-old was handcuffed and placed into a patrol vehicle, where he tried to kick out a window and threatened to kill an officer, police say.Two adults, Paris R. Leverston Sr., 37, and Laquita, became upset when the 17-year-old was arrested. According to Bloomington police, "Attempts were made to explain to her the reason why, but both adults continued to be loud and disruptive." Both were arrested.All weapons seized by police were BB guns, not actual guns.The people arrested face the following charges: 1729

  

Beginning in the fall of 2023, all California State University students will be required to take a three-unit ethnic studies or social justice course to graduate.“Automatic yes,” said Jose Juan Rodriguez Gutierrez Hernandez Estrada, a wildlife biology major at Humboldt State University. “I’m glad that’s something that’s going to be required.”In addition to his studies, Rodriguez also makes music about social issues and also plays on the HSU men's rugby team.For the student-athlete, this change in curriculum shows a commitment to much needed change.“I feel like making ethnic studies would go a long way, not just for students of color but for our society in general,” he said.University leaders say these courses will have their own section in the general education curriculum, as social science requirements have been lowered from nine to six units.“We feel that it really is time to make this change,” said Alison Wrynn, Ph.D., CSU associate vice chancellor.Wrynn says this decision is the first major change to the CSU system’s general education requirements in 40 years.“Whether you’re an engineer or a nurse, it’s important for you to understand the communities you’re working with as you make those professional discipline-based decisions,” she said.Some college leaders, however, say this change is not nearly enough“We are absolutely opposed to it,” said Charles Toombs, Ph.D., a professor of Africana Studies at San Diego State University.Toombs is also president of the California Faculty Association, the union that represents the 29,000 faculty members in the CSU system and a group he says was not included enough in the decision making.“The BOT (Board of Trustees) did not listen to our voices,” he said. “CSU’s proposal is diluting what ethnic studies is; it’s trying to include everything in ethnic studies.”Toombs and other representatives from the CFA are pushing for Assembly Bill 1460 – which would require students to take a class focusing on one of four ethnic groups: African Americans, Latin X, Asian Americans and indigenous groups.“It will actually give students essential knowledge that they need in the 21st century,” Toombs said.As the bill sits on the California governor’s desk, Rodriguez believes these new requirements are a good start for future change.“I feel like these lessons we can take with us and teach to our children, teach to the next generations,” he said. 2415
