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

BEIJING (AP) — While China appears to have reduced coronavirus cases to near zero, other infectious threats remain, with local health authorities announcing a suspected bubonic plague case in the Inner Mongolia Autonomous Region.Authorities in the Bayannur district raised the plague warning on Sunday, ordered residents not to hunt wild animals such as marmots and to send for treatment anyone with fever or showing other possible signs of infection.The case was reported at a people’s hospital in Urad Middle Banner, according to state-run Xinhua news agency.Xinhua reports that the third-level plague warning for prevention and control will last until the end of the year.Plague can be fatal in up to 90% of people infected if not treated, primarily with several types of antibiotics.Pneumonic plague can develop from bubonic plague and results in a severe lung infection causing shortness of breath, headache and coughing.Health authorities in China have announced a suspected case of bubonic plague in the Inner Mongolia Autonomous Region. 1052

BUFFALO, N.Y. -- Buffalo police officers are no longer required to display their names on their badges after a change in departmental rules. Officers will now be required to wear badges that show a badge number instead. According to Mayor Byron Brown, the change was made about a week ago due to ongoing concerns for officer safety. Brown says officers have been subjected to online threats, targeting them and their families. 434

Bank of America announced on Tuesday that they plan to stop lending money to companies that make assault-style guns used for non-military purposes.During an interview on Bloomberg television, Bank of America Vice Chairman Anne Finucane said, “It’s not our intent to underwrite or finance military-style firearms on a go-forth basis.”According to Finucane, the firm has had “intense conversations over the last few months” with those kinds of gun manufacturers to let them know "it's our intention not to finance these military-style firearms for civilian use."According to CNBC, the bank is a lender to Vista Outdoor, Remington and Sturm Ruger.The move comes as part of a national movement addressing gun control that was put into motion after a gunman opened fire on a Florida high school killing 17 people. Mary Stringini is a Digital Reporter for ABC Action News.

BRUCE TOWNSHIP, Michigan — A company that supplies equipment to the University Hospitals fertility center said its storage tank did not malfunction. “The early stages of our investigation into this unfortunate incident indicate it was the result of human error,” Custom Biogenic Systems said in a detailed statement sent to E.W. Scripps Co. TV station WEWS in Cleveland, Ohio.In a letter to patients on March 26, University Hospitals said that a remote alarm system on a storage tank that was designed to alert a University Hospitals employee to changes like temperature swings was turned off. UH said that on the evening of Saturday, March 3, the temperature inside the tank, which contained thousands of eggs and embryos, rose. UH does not know when the alarm was turned off. During the period when the alarm was off, UH said it had been experiencing “difficulty with what is called the liquid nitrogen automatic fill on the storage tank” for “several weeks.” Liquid nitrogen is added to the storage tank to keep specimens frozen, and it can be added manually or automatically. According to UH, “We had been working with the tank manufacturer who had previously provided instructions on the necessary maintenance to ‘thaw’ the storage tank to correct this difficulty. To do that required transferring all specimens to an extra storage tank previously provided by the manufacturer. This process takes several weeks, and had begun when this event occurred, though no eggs or embryos had yet been moved to the extra tank.”Custom Biogenic Systems, of Bruce Township, Mich., says the extra tank was available to UH on Aug. 15, 2017, UH finalized its arrangements for delivery of the tank on Oct. 27, 2017, and the tank was delivered on Nov. 2, 2017. That’s almost four months to the day before 950 UH patients lost 4,000 eggs and embryos in an event the hospital would later call “catastrophic." With the automatic fill not working on the original tank, UH added liquid nitrogen to the tank manually. This was done by connecting the storage tank with a line to a tank of liquid nitrogen from the Embryology Lab. But, according to UH, “For several days prior to the weekend in question, a manual fill could not be done using the line in the Embryology Lab because there were no liquid nitrogen tanks available. So, containers of liquid nitrogen were obtained from the Andrology Lab. Those containers were then manually poured into the top of the tank, while amounts of liquid nitrogen and temperature were monitored.” Custom Biogenic Systems says its tank is not designed to be filled by liquid nitrogen poured into the top of the tank.The company said its product manual states:  2744
