(KGTV) — Attorney General William Barr has decided to self-quarantine out of caution after President Donald Trump and several other lawmakers and aides tested positive for the coronavirus this week.Barr has had four COVID-19 tests since Friday and all have been negative, according to Justice Department spokesperson Kerri Kupec. She told the AP that Barr is quarantining out of an abundance of caution.Barr had attended one meeting at the Justice Department headquarters on Friday and stayed home during the weekend except to be tested.RELATED:President Trump drives by his supporters outside Walter Reed8 attendees of Trump's Supreme Court announcement test positive for the coronavirusLast weekend, Barr was one of several people to attend a White House event for Supreme Court nominee Amy Coney Barrett, where he was seen on video talking with former Trump aide Kellyanne Conway, who has since tested positive for the virus. Neither was wearing a mask.Many others in attendance were also not wearing a facial covering, as they sat close together throughout the ceremony. Since that event, at least eight people have tested positive for the coronavirus, including President Trump, first lady Melania Trump, Sens. Tom Tillis, and Mike Lee, Notre Dame President John I. Jenkins, Gov. Chris Christie, and Conway.The Associated Press contributed to this report. 1368
(CNN) -- Scientists have discovered a "monster black hole" so massive that, in theory, it shouldn't exist.It's a stellar black hole — the type that forms after stars die, collapse, and explode. Researchers had previously believed that the size limit was no more than 20 times the mass of our sun because as these stars die, they lose most of their mass through explosions that expel matter and gas swept away by stellar winds.This theory has now been toppled by LB-1, the newly-discovered black hole. Located about 15,000 light years away, it has a mass 70 times greater than our sun, according to a press release from the Chinese Academy of Sciences.The findings were published by Chinese researchers in the journal Nature on Wednesday."Black holes of such mass should not even exist in our galaxy, according to most of the current models of stellar evolution," said Liu Jifeng, head of the team that made the discovery. "LB-1 is twice as massive as what we thought possible. Now theorists will have to take up the challenge of explaining its formation."Scientists are now scratching their heads at how LB-1 got so huge.The Chinese team has proposed a number of theories. LB-1's sheer size suggests that it "was not formed from the collapse of only one star," the study said -- instead, it could potentially be two smaller black holes orbiting each other.Another possibility is that it formed from a "fallback supernova." This is when a supernova -- the last stage of an exploding star -- ejects material during the explosion, which then falls back into the supernova, creating a black hole.This fallback formation is theoretically possible, but scientists have never been able to prove or observe it. If this is how LB-1 formed, then we may have "direct evidence for this process" for the first time, the study said.LB-1 is not the biggest black hole ever discovered -- but it may be the largest of its kind. There are several types of black holes, and stellar black holes like LB-1 are on the smaller side, according to NASA. Supermassive black holes are much bigger -- they can be billions of times the mass of our sun.Scientists believe supermassive black holes may be connected to the formation of galaxies, as they often exist at the center of the massive star systems -- but it is still not clear exactly how, or which form first.Stellar renaissanceStellar black holes are believed to be commonly scattered across the universe, but they are difficult to detect because they do not normally emit X-rays -- only doing so when they gobble up gas from a star that has ventured close enough. They are so elusive that scientists have only found, identified, and measured about two dozen stellar black holes, the press release said.The researchers at the Chinese Academy of Sciences tried a different approach. Instead of looking for X-rays emitted by black holes, the team looked for stars that were orbiting some invisible object, being pulled in by its gravity.Their efforts paid off -- they soon spotted a giant star eight times heavier than the sun, orbiting around what turned out to be LB-1."This discovery forces us to re-examine our models of how stellar-mass black holes form," said David Reitze, a physicist at the University of Florida. In May, Reitze's team made its own breakthrough discovery -- observing the never-before-seen collision of a neutron star and a black hole, which sent out ripples in space and time.These twin discoveries -- the collision, and now LB-1 -- indicate that scientists are reaching "a renaissance in our understanding of black hole astrophysics," said Reitze in the press release.There have been several other discoveries over the past year that have added to this renaissance. In October, researchers discovered what they believe to be a new type of black hole, smaller than the other kinds. And earlier this week, astronomers discovered a black hole that is actually helping baby stars grow instead of destroying them. 3971

(KGTV) — A Fresno man died after not long after taking part in a taco-eating contest at a Minor League Baseball game Tuesday.Dana Hutchings, 41, died shortly after arriving at a hospital following the contest at a Fresno Grizzlies game Tuesday, according to Fresno County Sheriff's Office.ABC-affiliate KFSN reported Hutchings was taken from Chukchansi Park by an ambulance where he had just competed in a taco-eating contest before the game started. According to the Associated Press, a witness said Hutchings appeared to be eating much faster than the other two contestants, swallowing tacos without chewing them.The witness added that Hutchings collapsed about seven minutes into the contest and hit his face on the table as he fell to the ground, the AP said.A cause of death has not been released. Fresno sheriff's spokesman Tony Botti told reporters an autopsy will be performed Wednesday. Botti added that paramedics had to clear Hutchings' airway of food when he was transported, but it wasn't clear how many he had eaten.According to the AP, the Grizzlies has canceled the World Taco Eating Championship scheduled for Saturday at the annual Taco Truck Throwdown. Tuesday's contest, however, was not related to the championship event. 1250
(KGTV) - In a crowded field of Democratic presidential hopefuls, an exclusive 10News Union-Tribune nationwide poll breaks down which candidates voters believe would fare best against President Trump. With the Iowa Caucus 139 days away and 169 days before Super Tuesday, the Democratic support lines up with Joe Biden holding a 33 percent lead, unchanged since July’s debate in Detroit. 394
(CNN) -- Maui residents who evacuated their homes because of a wildfire are allowed to return, the County of Maui announced Friday on Facebook.But Maui County Mayor Michael Victorino cautioned that, "This fire is still an active threat to our community, and residents are urged to remain vigilant of changing conditions," in the same post.Firefighters will continue to monitor the blaze that has consumed an estimated 10,000 acres of fallow former sugar cane and dry brush, according the county.The fire was reported Thursday morning at 10:42 a.m. local time near the intersection of Waiko Road and Kuihelani Highway.The County of Maui activated its Emergency Operations Center in the morning. By afternoon, the flames were burning out of control and emergency officials sent a mobile alert warning nearby residents to evacuate.More than 600 people fled as the blaze scorched 3,000 acres, the mayor's office said. The Maui Humane Society moved its animals in crates and kennels to a nearby high school.Helicopters were grounded after sunset, and they are expected to return to making air drops after sunrise, according to a news release from the county.Oprah Winfrey has a home in the county, and tweeted a local resident to confirm that she's given officials fighting the fire access to her private road. "A big mahalo to Oprah for giving Maui County access to your private road for use to assist in the Maui fire," Hawaii Gov. David Ige tweeted.Flights at Kahului Airport were briefly diverted, but operations have returned to normal. The fire affected access to the airport, which was operating on emergency generators. The Hawaii Tourism Authority advised visitors heading to or from the airport to contact their airlines for flight status due to power issues. 1773
