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 Centers for Disease Control and Prevention said on Thursday that they have increased the number of cases of lung injury and deaths associated with e-cigarette product use to 805. Of those 805 cases, there have been 12 fatalities. The 12 fatal cases have been reported in 10 states, including two in both California and Kansas. Two weeks ago, the CDC opened its Emergency Operations Center after 380 confirmed cases of lung damage caused from vaping. Given recent reports of deaths tied to smoking electronic cigarettes, the Centers for Disease Control and Prevention said on Monday it is activating its Emergency Operations Center.The CDC said that activating the Emergency Operations Center "allows the agency to provide increased operational support for the response to meet the outbreak’s evolving challenges. Agency subject matter experts will continue to lead the CDC response with enhanced support from additional CDC and EOC staff."The CDC has stressed that it does not know exactly what is causing an outbreak of lung disease among those who vape. The CDC said that its investigation has not identified any specific e-cigarette or vaping product (devices, liquids, refill pods, and/or cartridges) or substance that is linked to all cases.“CDC has made it a priority to find out what is causing this outbreak of e-cigarette or vaping-related injuries and deaths,” said CDC Director Robert Redfield, M.D. “Activation of CDC’s Emergency Operations Center allows us to enhance operations and provide additional support to CDC staff working to protect our Nation from this serious health threat.” 1615

The Environmental Protection Agency is proposing a new rule that would ease the regulation of methane emissions at a time when greenhouse gas emissions are at their highest -- the latest rollback of an environmental protection introduced under former President Barack Obama. 286
