A dentist in New York says she's been seeing patients more than ever since the coronavirus pandemic began. She says it has nothing to do with anyone being sick, but with what she calls the "epidemic of cracked teeth."Prosthodontist Tammy Chen detailed that coronavirus-related stress leads people to clench and grind their teeth in a New York Times article."Teeth are naturally brittle, and everyone has tiny fissures in their teeth from chewing, grinding, and everyday use," Chen wrote. "They can take only so much trauma before they eventually break."Chen also attributed a lack of sleep and how people sit while working from home as to why she's seeing more patients in her dentist chair."If you're wondering why a dentist cares about ergonomics, the simple truth is that nerves in your neck and shoulder muscles lead into the temporomandibular joint, or TMJ, which connects the jawbone to the skull," Chen stated in the NYT piece. "Poor posture during the day can translate into a grinding problem at night."Chen recommends being mindful of your top and bottom teeth touching each other. The only time they should be doing that, Chen said, is while eating.She also said to wear a nightguard or retainer during the day, setting up a proper space to work and moving around during your eight or 9-hour workday. 1319

A man convicted of sexually assaulting a sleeping woman on an overnight flight from Las Vegas to Detroit was sentenced on Thursday to nine years in prison, according to federal prosecutors.Prabhu Ramamoorthy, 35, was convicted in August of sexual abuse onboard an aircraft. Jurors deliberated for less than four hours before returning the guilty verdict.Authorities say that during an Spirit Airlines flight in January, Ramamoorthy put his hand down the pants of the woman sitting next to him and molested her while she slept."The sexual assault woke her up, she found her pants unbuttoned and unzipped, and she sought help from the flight attendants," according to a statement from the US Attorney's Office.Ramamoorthy was taken into custody when the flight landed.His attorneys did not immediately respond to CNN's request for comment on the sentencing."The sentence announced today is proof that the safety and security of all aircraft passengers is a priority for the FBI, our local and federal law enforcement partners, and airline personnel," Timothy R. Slater, the Special Agent in Charge of the FBI's Detroit Division said in a statement. "If you, or someone you know, is the victim of a crime during air travel, immediately notify a flight crew member, airport security police, and the FBI."The government said Ramamoorthy is in the United States on a work visa and that he will be deported after he serves his sentence. The statement did not say what country he is from.It is difficult to determine how often this sort of abuse happens on commercial flights, but FBI investigations into midair sexual assaults have increased by 66% from fiscal year 2014 to 2017. 1690

A growing number of countries are banning travelers from the United Kingdom after a new coronavirus variant was found there.A variant or mutation happens when the genetic structure of a virus changes and this is common.The variant first appeared in September. Health experts have found it is more infectious than the original virus.“Let me tell you what, there is no evidence of nor reason to believe, it is not any more lethal or any more dangerous than the normal coronavirus, no evidence to suggest that, no reason to believe it,” said Admiral Brett Giroir, Assistant Secretary for Health at the Department of Health and Human Services (HHS).The variant has already been found in Australia, Denmark, South Africa and the Netherlands. Italy reports it has at least one patient infected with the mutation.While the U.K. works to control the new variant, several countries have banned flights coming from there, as well as countries where they've seen such infections.Despite the mutation, health officials remain adamant that it's important to get the COVID-19 vaccine.“There is also no evidence to suggest nor reason to believe that it would evade our vaccines that we have right now. Remember, our vaccines developed antibodies against multiple parts of that spiked protein, not just one that's the mutated one, so we are very encouraged about that,” said Giroir.A U.S. travel ban that began in March regarding the U.K. is still in place. 1449

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 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
