The moon is slowly shrinking over time, which is causing wrinkles in its crust and moonquakes, according to photos captured by NASA's Lunar Reconnaissance Orbiter.Unlike Earth, the moon doesn't have tectonic plates. Instead, as the moon's interior has cooled over the last several hundred million years, it has caused the surface to wrinkle as it shrinks. Unlike the flexible skin of a grape when it shrinks into a raisin, the moon's brittle crust breaks. This creates stair-step cliffs called thrust faults as part of the crust is pushed up and over another close part of the crust.There are now thousands of cliffs scattered across the moon's surface, averaging a few miles long and tens of yards high. The orbiter has taken photos of more than 3,500 of them since 2009. In 1972, Apollo 17 astronauts Eugene Cernan and Harrison Schmitt had to ascend one of these cliffs, the Lee-Lincoln fault scarp, by zig-zagging the lunar rover over it.Today the moon is 50 meters "skinnier" because of this process. And as it shrinks, the moon actively produces moonquakes along the faults. Researchers re-analyzed seismic data they had from the moon to compare with the images gathered by the orbiter.Data from the seismometers placed on the moon during the Apollo 11, 12, 14, 15 and 16 missions revealed 28 moonquakes recorded between 1969 and 1977. Researchers compared the location of the epicenters for those quakes with the orbiter imagery of the faults. At least eight of the quakes occurred due to activity along the faults. This rules out the possibility of asteroid impacts or rumblings from the moon's interior.This means that the Apollo seismometers recorded the moon shrinking, the researchers said. The study of Apollo seismic data and analysis of more than 12,000 of the orbiter's photos were published Monday in the journal 1841

Terrorism is an age-old concept.Some people think the first attack happened in the first century against Roman collaborators.But modern terrorism is thought to come out of mid-19th century France, when good-quality, affordable explosives hit the market and radical political movements became more prominent.It came to the U.S. during the same time frame.Today, the terrorism landscape is much different, and so is the response.The FBI says its No. 1 priority is protecting the U.S. from terrorist attacks, regardless of motivation.Terrorism investigations fall into two categories at the FBI: international terrorism and domestic terrorism.The first is when an attack is inspired by or associated with foreign organizations or nations.If the attack or attacks are meant to further a domestic influence’s goals, it’s domestic terror.The FBI’s examples of domestic terror motivations include politics, religion, race and social issues.Domestic terror “remains persistent” overall, according to the FBI.The FBI says people cross the line from exercising First Amendment freedoms to committing crimes in hopes of furthering violent agendas.Terrorism has evolved immensely since 9/11.The FBI says lone offenders and the internet have accelerated that evolution.According to the FBI, lone offenders are tougher to identify and stop because they aren’t always clearly tied to a group.And the internet — social media, in particular — helps terrorists connect with potential recruits more easily.To meet the evolving threat, law enforcement is constantly changing its approach. 1580

The National Hurricane Center has issued a hurricane warning for sections of the Louisiana coast as Tropical Storm Barry is churning the in the Gulf of Mexico. Barry remains a minimal tropical storm with 40 MPH winds, but is expected to gain strength as it turns toward the Louisiana coast. The National Hurricane Center expects the storm to make landfall during the middle of the day Saturday. The National Hurricane Center said a Hurricane Warning is now in effect for the coast of Louisiana from Intracoastal City to Grand Isle.Despite the disorganized nature of Barry on Thursday, the storm is in a favorable environment for strengtheningThe biggest impact of Barry could be the rain, which could cause flooding. The slow-moving storm could cause some areas to recieve more than a food of snow. 812

The Cherokee Nation has named an official representative to Congress for the first time.Kimberly Teehee, executive director of government relations for the Cherokee Nation, was approved by the Council of the Cherokee Nation as a delegate to the US House of Representatives on Thursday, fulfilling a promise made to the tribe in a nearly 200-year-old treaty with the federal government.A former senior policy adviser for Native American Affairs during President Barack Obama's administration, she was nominated by Chuck Hoskin Jr., chief principal of the Cherokee Nation. She is also a former senior adviser to the US House Native American Caucus Co-Chair former Rep. Dale Kildee and has held various positions within the Cherokee Nation.The treaty doesn't specify if Teehee would be a voting member of the legislature, and her appointment requires congressional approval. But Hoskin said her role may be similar to those who represent Washington, DC, and five US territories -- Puerto Rico, American Samoa, Guam, the US Virgin Islands and the Northern Mariana islands -- who can't vote on the House floor but can introduce legislation, vote in their respective committees and debate on the floor.Teehee said in a statement to CNN on Tuesday she is "humbled" to be nominated for an "extraordinary responsibility" and is grateful for an opportunity to serve the Cherokee Nation."This journey is just beginning and we have a long way to go to see this through to fruition," she said. "However, a Cherokee Nation delegate to Congress is a negotiated right that our ancestors advocated for, and today, our tribal nation is stronger than ever and ready to defend all our constitutional and treaty rights. It's just as important in 2019 as it was in our three treaties."Teehee's historic nomination stems from a 1835 Treaty of New Echota in which the Cherokee were forced to leave their homes in the Southeast and go to present-day Oklahoma in exchange for money and other compensation. Nearly 4,000 citizens of the tribe died from disease, starvation and exhaustion on the journey known today as the Trail of Tears. As a way to compensate the tribe, the US government promised them a delegate in the House of Representatives.Hoskin Jr. said Teehee is "extremely qualified" for the position and, through her nomination, the Cherokee Nation is "exercising our treaty rights and strengthening our sovereignty.""We know this is just the beginning and there is much work ahead, but we are being thorough in terms of implementation and ask our leaders in Washington to work with us through this process and on legislation that provides the Cherokee Nation with the delegate to which we are lawfully entitled," he said in a statement to CNN on Tuesday.Victoria Vazquez, deputy speaker of the council, said Teehee's political experience made her confirmation as delegate an "easy decision.""Ms. Teehee has a wealth of experience working in Washington, DC with representatives from both sides of the aisle. She also has a storied career of advocating and working on issues for both the Cherokee Nation and Indian Country in general," Vazquez said. "These two attributes make her appointment as the first-ever delegate an easy decision and I am happy to support her nomination and Chief Hoskin's efforts to exercise our treaty rights." 3331
