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

Between Black Friday, Cyber Monday and Thanksgiving hangovers, it's easy to forget about the most important parts of the holiday season. Luckily, Giving Tuesday has arrived to get you back on track.Celebrated the Tuesday after Thanksgiving every year, Giving Tuesday began in 2012 as a partnership between New York's 92nd Street Y and the United Nations Foundation with one stated goal: Encourage people to do good.Giving Tuesday can be whatever you want it to be: Donating to a charity, helping out a friend in need, trying to brighten a coworker's day — anything that "builds a more just and generous world."In the last eight years, the movement has exploded around the world. According to GivingTuesday.org, the event was celebrated in more than 150 countries in 2018, leading to more than 0 million raised for charity by 3.6 million people.In 2019, Giving Tuesday was spun off into its own organization, and now offers social media toolkits and other resources to nonprofits ahead of the holiday, If you'd like to participate in Giving Tuesday, click here to find a nonprofit or charity that's holding an event near you.Alex Hider is a writer for the E.W.

BOCA RATON, Fla. - Three sisters in Boca Raton do not remember much about their mom, but as Mother’s Day approaches, they are reminded those are the only memories of her they will ever have. “One memory about my mom is that she would always take me places and let me play with my things,” said 9-year-old Brady Gemstone.“I remember mommy’s pointy nose, and that she dyed her hair,” 5-year-old Blain Gemstone said.“She was very understanding and nice,” said 11-year-old Bryce Gemstone, “and she was always there.”But one day, Gemma Burlakoff wasn’t there anymore for her three girls. That memory stings the most.“I’m happy because I still have someone to do [Mother’s Day] with, but I’m sad because I don’t have my real mom to do it with,” the youngest, Blain said, clutching a doll as she spoke.“Sometimes if I think about my mom, I think about my dad, and it makes me think about what happened,” said Brady, who remembers the most about the night her mother was killed, The Gemstone sister did not just lose their mother. They lost their father too.One fight, five years agoOn the outside, Gemma and Ian Burlakoff looked like the picture-perfect Boca Raton couple: a successful business, a large home, society and community involvement, designer outfits and cars, and their three beautiful daughters enjoyed an education at an expensive private school.  1372

BOWIE, Maryland — Some students at Bowie High School in Prince George's County may face charges for a senior prank they pulled at the school last week.About 20 seniors stormed the school's hallways, taking part in what was meant to look like a school shooting.The seniors used fireworks and water guns and were wearing black masks, according to a letter from the school.The school was evacuated.One student was burned by the fireworks and also treated for an asthma attack.The father of that student was shocked to learn what had happened."I don't know what had to go through somebody's mind to pull of a prank like this in this day and age, so close to Parkland and two days later they had a shooting today down in Texas," said Steve Birckhead, father of the injured student. "These kids just weren't thinking."School officials say the students who participated in the prank will be held accountable to the fullest extent of the law. 952
