A group of Pac-12 football players says it won't practice or play until its concerns about playing during the COVID-19 pandemic and other racial and economic issues in college sports are addressed. “We believe a football season under these conditions would be reckless and put us at needless risk,” the players said in their news release. “We will not play until there is real change that is acceptable to us.”The players posted a statement on The Players' Tribune website and on social media and sent out a news release. One of the players tells The Associated Press that more than 400 of his peers throughout the Pac-12 have been communicating about the issues they are raising. The players are concerned about the risks of COVID-19 and think the conference and NCAA lack transparency, uniformity and adequate enforcement infrastructure. The news release listed the names of 13 Pac-12 players, including Oregon star safety Jevon Holland.The NCAA has released guidelines for COVID-19 testing and other health and safety protocols to be used by schools, and Power Five conferences — the Pac-12, Big Ten, Big 12, ACC and SEC — are finalizing their own similar recommendations.The Pac-12 also announced Friday that 20 hours per week of mandatory team activities for football, including weight training, meetings and unpadded walk-through practices, will be permitted to begin Monday. Preseason football practice for Pac-12 schools is set to begin Aug. 17.The states of Arizona and California, home to half the Pac-12 schools, have been hit by some of the most severe surges in COVID-19 cases over the last month. California-Berkeley has announced the fall semester will begin with all classes being taught online. USC said most of its classes will be online for the coming semester. 1788

A Chinese lunar capsule returned to Earth on Thursday with the first fresh rock samples from the moon in more than 40 years, offering the possibility of new insights into the history of the solar system and marking a new landmark for China’s rapidly advancing space program.The capsule of the Chang’e 5 probe landed just before 2 a.m. (1800 GMT Wednesday) in the Siziwang district of the Inner Mongolia region, the China National Space Administration reported.The capsule had earlier separated from its orbiter module and performed a bounce off Earth’s atmosphere to reduce its speed before passing through and floating to the ground on parachutes. Following recovery, the capsule and its cargo of samples were flown to the space program’s campus in Beijing to begin the process of disassembly and analysis, the space administration said.The mission achieved new firsts for the lunar exploration program in collecting samples, launching a vehicle from the moon’s surface and docking it with the capsule to return the samples to Earth, the administration said.“As our nation’s mostly complex and technically groundbreaking space mission, Chang’e 5 has achieved multiple technical breakthroughs ... and represents a landmark achievement,” it said.Two of the Chang’e 5’s four modules set down on the moon on Dec. 1 and collected about 2 kilograms (4.4 pounds) of samples by scooping them from the surface and drilling 2 meters (about 6 feet) into the moon’s crust. The samples were deposited in a sealed container that was carried back to the return module by an ascent vehicle.Much to the amusement of viewers, footage run by state broadcaster CCTV showed a furry white animal, possibly a fox or rodent, running in front of the capsule as it lay on the ground, stopping briefly as if to inquire into the unfamiliar object.Chinese leader Xi Jinping, in a statement read out at the Beijing Aerospace Control Center, called it a major achievement that marked a great step forward for China’s space industry. Xi expressed hope that mission participants would continue to contribute toward building China into a major space power and national rejuvenation, state-run Xinhua News Agency said.Recovery crews had prepared helicopters and off-road vehicles to home in on signals emitted by the lunar spacecraft and locate it in the darkness shrouding the vast snow-covered region in China’s far north, long used as a landing site for China’s Shenzhou crewed spaceships.The spacecraft’s return marked the first time scientists have obtained fresh samples of lunar rocks since the former Soviet Union’s Luna 24 robot probe in 1976.The newly collected rocks are thought to be billions of years younger than those obtained earlier by the U.S. and former Soviet Union, offering new insights into the history of the moon and other bodies in the solar system. They come from a part of the moon known as the Oceanus Procellarum, or Ocean of Storms, near a site called the Mons Rumker that was believed to have been volcanic in ancient times.As with the 382 kilograms (842 pounds) of lunar samples brought back by U.S. astronauts from 1969 to 1972, they will be analyzed for age and composition and are expected to be shared with other countries.The age of the samples will help fill in a gap in knowledge about the history of the moon between roughly 1 billion and three billion years ago, Brad Jolliff, director of the McDonnell Center for the Space Sciences at Washington University in the U.S. city of St. Louis, wrote in an email. They may also yield clues as to the availability of economically useful resources on the moon such as concentrated hydrogen and oxygen, Jolliff said.“These samples will be a treasure trove!” Jolliff wrote. “My hat is off to our Chinese colleagues for pulling off a very difficult mission; the science that will flow from analysis of the returned samples will be a legacy that will last for many, many years, and hopefully will involve the international community of scientists.”Chang’e 5 blasted off from a launch base in China’s southern island province of Hainan on Nov. 24 and appeared to have completed its highly technically sophisticated mission without a hitch.It marked China’s third successful lunar landing but the only one to lift off again from the moon. Its predecessor, Chang’e 4, became the first probe to land on the moon’s little-explored far side and continues to send back data on conditions that could affect a future extended stay by humans on the moon.The moon has been a particular focus of the Chinese space program, which says it plans to land humans there and possibly construct a permanent base. No timeline or other details have been announced.China also has joined the effort to explore Mars. In July, it launched the Tianwen 1 probe, which was carrying a lander and a robot rover to search for water.In 2003, China became the third country to send an astronaut into orbit on its own after the Soviet Union and the United States and its space program has proceeded more cautiously than the U.S.-Soviet space race of the 1960s, which was marked by fatalities and launch failures. By taking incremental steps, China appears on the path toward building a program that can sustain steady progress.The latest flight includes collaboration with the European Space Agency, which is helping to monitor the mission. Amid concerns over the Chinese space program’s secrecy and close military connections, the U.S. forbids cooperation between NASA and the CNSA unless Congress gives its approval. That has prevented China from taking part in the International Space Station, something it has sought to compensate for with the launching of an experimental space station and plans to complete a permanent orbiting outpost within the next two years.___This report corrects the date of the Chang’e 5 mission’s launch. 5854

  

A hearing will be held Wednesday to determine whether Florida school shooter Nikolas Cruz can afford to hire his own attorneys so taxpayers can stop paying for his public defender.Cruz killed 17 students and faculty at Marjory Stoneman Douglas High School in Parkland on February 14 in one of the deadliest mass shootings in the US.Before the massacre, Cruz told a family he was living with that he was set to inherit 0,000 from his deceased parents, most of which would come when he turned 22. 505

  

A growing group of Republicans want Attorney General Jeff Sessions to be the party's choice in the Alabama Senate race, but ethics experts say Sessions either would have to have to leave the Department of Justice or continually disavow campaigns to put him in the seat if he wants to run for the office and avoid legal trouble.This week Senate Majority Leader Mitch McConnell of Kentucky and Senate Majority Whip John Cornyn of Texas both said they would support Sessions as a write-in candidate over Republican candidate Roy Moore, who has been accused of pursuing sexual relationships with teenagers when he was in his 30s.Moore denies the allegations, and says he has no plans leave the race. And Sessions has not indicated that he's planning to run for his old seat.But ethics experts say that even if Sessions does not himself campaign to be a write-in candidate in the race, he could have an "affirmative duty" to disavow campaigns to put him in the Senate while he's still the attorney general. If he remains silent, he could be in violation of the Hatch Act, a 1939 law restricting the ability of most federal employees to engage in political campaign activities.Walter Shaub, a former director of the US Office of Government Ethics who's now at the nonprofit Campaign Legal Center, told CNN that the federal Office of Special Counsel has issued an advisory opinion on write-in candidates, which specifies:"(S)uch a candidacy is permissible only if spontaneous and accomplished without an employee's knowledge. You acknowledge that you have heard rumors of a write-in effort to elect you to the school board. It would be a violation of the Act if you encouraged this effort or remained silent. The Act imposes on you an affirmative duty to disavow this effort through public announcements and other appropriate means." It remains to be seen whether the OSC considers the comments by McConnell and Cornyn as imposing an "affirmative duty.""There's a question as to whether it's a write-in campaign or a stray comment from one guy," Shaub said following McConnell's comments. "If McConnell keeps talking about it, he's going to create an affirmative duty."Larry Noble, a senior director at the Campaign Legal Center who's a CNN contributor, said Republicans such as McConnell are "putting (Sessions) in a very difficult position" by even suggesting he be a write-in candidate."We are close to the line of his having to disavow," Noble added.For Sessions to be eligible as a write-in candidate, Noble said, he would have to "affirmatively disavow" any campaign or resign from office to avoid violating the Hatch Act.Sessions would likely be asked about his support for the write-in candidacy frequently until the December 12 election. Questions could also be raised about whether he was having private conversations about the effort with the state party and the Republican National Committee, which also would violate the Hatch Act.In response to a request for comment, Sarah Isgur Flores, director of public affairs for the Department of Justice, said, "Our ethics officials will need to evaluate precisely what has been said by others and then review what, if any, affirmative obligations we may have."Samuel Bagenstos, a University of Michigan Law School professor who specializes in constitutional litigation, noted that a few previous attorneys general -- including Dick Thornburgh and Robert Kennedy -- have campaigned for Senate seats, but neither were floated as write-in candidates."It's extremely suboptimal for an attorney general, who is supposed to have some insulation from electoral politics, to be actively running for a political office," Bagenstos said, adding, "And of course there would be lots of possible recusal questions."Aside from ethical considerations, running as a write-in candidate would be a long shot even if Sessions resigned.Few candidates have won Senate seats via write-in campaigns. Sen. Lisa Murkowski, R-Alaska, won her seat that way in 2010, but prior to her election the last person to do it was Strom Thurmond in 1954.However unlikely, a Sessions victory would serve two purposes for the GOP: The party would retain the seat, and Sessions would leave the DOJ after months of public criticism by President Donald Trump over his decision to recuse himself from the Russia investigation and not to prosecute Trump's political enemies. 4412
