Jam Cruise is the gift that keeps on giving!While our favorite musical-adventure-at-sea is only a few days long, the amount of music packed on board can last an entire year (and create memories for a lifetime). This past sailing, Jam Cruise was honored to have the incredible super-group Joe Russo’s Almost Dead as a headliner, and they certainly did not disappoint! Check out the group performing the classic Grateful Dead combo of “Help On The Way” -> “Slipknot” from their Pantheon Theater set from this year’s Jam Cruise 14 and try not to get all the feels.
A research team of nuclear physicists headed by Notre Dame faculty members is looking to the cosmos for the answers to questions about the origins of Earth’s most influential elements. The team, comprised of researchers from several American universities, was awarded a one-year, $1.6 million grant from the National Science Foundation to develop the first U.S.-based underground accelerator laboratory, enabling them to progress towards a more complete understanding of the formation of the elements. Physics professor and principal investigator Michael Wiescher said the grant money will be used to fund testing of underground sites that could serve as locations for the Dual Ion Accelerator for Nuclear Astrophysics (DIANA). The key site in question is the Sanford Underground Research Facility in South Dakota, Wiescher said. “The grant basically covers the first test experiments going on right now, like the engineering studies that will allow us to stabilize the abandoned underground mines,” Wiescher said. “We also have graduate students who are measuring underground radiation and determining how feasible the site is for our purposes.” Wiescher said the goal of his nuclear astrophysics research is to understand the origin of the Earth’s elements and their formation process. The answers to these questions can help scientists discover what happens in the center of our sun, he said. “Nuclear astrophysics is mainly concerned with the origin of all the elements in the universe at the time the universe formed, about 30 billion years ago with the Big Bang,” Wiescher said. “The heavier elements, like uranium, gold and silver, are formed through the nuclear fusion processes that made in stars or supernova explosions,” he said. “[These explosions] need to be explored in more detail so we can determine how strong and how fast these reactions occur.” The great distance between Earth and the stars observed from Earth means the measurable energy from these nuclear reactions is minimal, Wiescher said, so the laboratory must be located underground in order to maintain the integrity of the reaction result. “Because these reactions are so weak, we need to go deep underground to be free of the cosmic radiation from the sun that alters our measurements,” he said. Wiescher said he hopes his team’s research will facilitate a more comprehensive understanding of the formation of the Earth, from the visible components to the more abstract. “All of the elements in your body have been made in stars, so you are the product of several star generations,” Wiescher said. “All stars are powered by nuclear fusion reactions that create elements. The light you see when you look at the stars is released from these nuclear fusion reactions.”

The NRA is also asking for a judicial declaration that the NRA complied with state law.“You could have set your watch by it: the investigation was going to reach its crescendo as we move into the 2020 election cycle,” Meadows said in a statement. “It’s a transparent attempt to score political points and attack the leading voice in opposition to the leftist agenda. This has been a power grab by a political opportunist – a desperate move that is part of a rank political vendetta. Our members won’t be intimidated or bullied in their defense of political and constitutional freedom.”In New York State’s lawsuit, James claims NRA leaders used millions of dollars from NRA reserves for personal use, including trips to the Bahamas, private jets and expensive meals.In a released statement, James said she will not back down on her efforts to dissolve the NRA, a key political opponent of the New York administration.“To be clear, no charity registered in New York state, including the NRA, can dissolve and relocate to another state without approval of my office or of the Supreme Court of New York. As long as our lawsuit continues, the NRA must stay right where it is and answer for their deep-rooted fraud. The facts speak for themselves and our lawsuit will continue undeterred,” James said.Earlier, President Donald Trump said the NRA should move to Texas.“That’s a very terrible thing that just happened. I think the NRA should move to Texas and lead a very good and beautiful life. And I’ve told them that for a long time. I think they should move to Texas,” Trump said.The suit also focused on longtime NRA executive vice president and CEO, Wayne LaPierre, who is accused of spending NRA funds on private trips for himself and his family.“This is an unconstitutional, premeditated attack aiming to dismantle and destroy the NRA – the fiercest defender of America’s freedom at the ballot box for decades,” LaPierre said in a statement. “The NRA is well-governed, financially solvent, and committed to good governance. We’re ready for the fight. Bring it on.”
