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

The city of Fresno doesn’t fit the California stereotype; it can be a tough city that raises tough kids. Kids like Jose Flores. “A lot of the violence around here, the drugs,” Flores says. Flores attends Duncan Polytechnical High School, and he’s on the welding track. All the students at Duncan are enrolled in a Career Technical Education. “We know that this is what our community needs, and frankly, this is what our community wants," said Jeremy Ward, who runs the College & Career Readiness program for Fresno Unified School District. "Jobs related to college really only speaks to a portion of the jobs that exist in the United States today. There are many skilled professions that are very well paid that have nothing to do with going to college." But it’s not just students at Duncan. Almost half of the students in Fresno are enrolled in CTE programs. The district thinks it’s one of the best ways to prepare students, who may not go to college, for some other real-world opportunities. “Students that are engaged in career technical education, there’s a heavy amount of data that shows that there’s a higher degree of graduation and that there’s a higher degree of post-secondary success, because of the experience they have by participating in a CTE program,” said Ward. At Duncan, students can enroll in welding, truck tech, manufacturing, and even nursing. “They are in a CNA program, by the time they graduate, they’ll have the requirements they need to take their state competency evaluation exam,” said Jodi Uyeg, a nursing teacher. “We get to work with real residents and practice the skills that we’ve learned here there; that way we’re ready for our CNA test in May,” said Evelyn Gamble, a nursing student. The idea is that these CTE programs give students a ton of options to join the workforce or go to college. Options they might need as rural areas like Fresno keep recovering from the recession. Just ask Ashley Swearingen, the former mayor of Fresno. “We went through as the city of Fresno, five years of consistent budget cuts," Swearengin said. "In some years, we were doing two or three budgets a year just to try and keep up with plummeting revenues, and of course, expenses were still going up." Swearingen has been working hard to try and help the area recover, but it hasn’t been easy. “We’ve struggled for a long time," said Swearingen. "I mean, this is a place that’s had chronic, double-digit unemployment for literally 30 to 40 years.” But schools like Duncan give kids in more rural areas a way to earn a good living or continue their education. For Flores, this opportunity was a big deal. “Growing up a lot of friends being killed a lot of gang violence,” said Flores. He’s been to more than a few funerals for friends his own age. “A lot of middle school friends that you know we were close, but we all went to different high schools," said Flores. "They all started doing their own things and even a couple of them are dead now, you know? It’s sad to say but that’s the life the chose. You think I’m going to know these people 30 years down the line and you know, it’s over right there." But he credits his family and the opportunities he’s had to keep him off the streets and alive. “Being around a lot of those people, it’s drags you in there,” he said. Instead, his future and Fresno’s is bright. 3372

The NCAA said on Monday that it has approved rules that allows conferences and universities to extend an additional year of eligibility for athletes whose season were cut short due to the spread of COVID-19. Earlier this month, the NCAA announced the cancellation of all spring and remaining winter championships. While most winter sports were just getting into postseason play, spring sports, such as baseball and softball, were just getting underway. Generally, the NCAA allows athletes four years that can be used over a five-year span. The ruling will allow athletes for spring sports to complete their four years of eligibility over six years. Teams will also be permitted to extend additional athletic scholarships to athletes to accommodate players opting to take advantage of an extra year of eligibility. Despite calls to also extend a year of eligibility for college basketball players, the NCAA opted not to add eligibility for those athletes. For many college basketball teams, their seasons had ended when most conferences decided on March 10 to suspend the rest of the season.“The Council’s decision gives individual schools the flexibility to make decisions at a campus level,” said Council chair M. Grace Calhoun, athletics director at Penn. “The Board of Governors encouraged conferences and schools to take action in the best interest of student-athletes and their communities, and now schools have the opportunity to do that.” 1457

The death of Luke Perry, after the actor suffered what his publicist said was a massive stroke, is evidence that the disease can affect people of any age, the American Heart Association said.Perry, who starred in "Beverly Hills 90210" and "Riverdale," died Monday. He was 52."Although stroke often affects older individuals, it is not only a disease of the elderly," said Mitchell S. V. Elkind, chair of the American Stroke Association Advisory Committee. "There is evidence that stroke rates among young people are increasing in the United States and this requires additional research."A 601

The Dow Jones traded below 20,000 for the first time since 2017 on Tuesday, but appeared to have stemmed some of the bleeding after Monday's 3,000 point loss.After an early peak, the Dow sunk about 200 points shortly after opening, leaving the markets trading at less than 20,000. But as Trump administration officials spoke about their plan to give 362
