(KGTV) - Are a growing number of Japanese companies banning female employees from wearing glasses?Yes.Several Japanese media outlets are reporting on this trend.Some retail chains reportedly say women employees who wear glasses give a "cold impression."One woman who works in a restaurant tweeted she was told not to wear her glasses because it would appear rude and did not go with her traditional kimono.Japanese companies were criticized earlier this year for requiring female employees to wear high heels. 517

(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) — As demonstrations around the country call for police reforms, demands for cities to "defund the police" have increased.But what does that really mean? Is it a reduction in funding or eliminating departments? So far, the calls have included both."There are some advocates who would like to see a police-free environment in a lot of cities," Scripps National Political Editor Joe St. George tells 10News' Jon Horn. "Now for some people that is a terrifying thought. Police help prevent theft, they prevent violent crime. So it is something that is certainly going to be a hotly contested political issue."RELATED: San Diego City Council approves budget, adds Office on Race & EquitySt. George added that both Republican President Donald Trump and Democratic nominee Joe Biden have both said they do not support calls to "defund the police," so the issue may fall on local cities.Policy proposals are still in the early stages. Supporters of the movement say they'd like to see less patrolling and reaction to major needs. But critics say patrolling helps prevent crimes from happening.If budget reductions are in the mix, depending on the amount, departments can either expect layoffs or a shift in priorities, according to St. George."If you're talking millions of dollars worth of cuts to a police department, there will have to be layoffs. If you're talking a couple hundred thousand, perhaps they would shift priorities from one program to another," St. George says.In San Diego, locals voiced their calls for decreasing the police department's budget for the 2021 fiscal year. City leaders voted Monday to approve the budget, which will increase SDPD's budget to 6 million.In contrast, Minneapolis' City Council has voiced intentions to disband the local department, calling their current department unreformable. City leaders have not announced plans for a future public safety agency.RELATED: Advocates calling to defund or disband police departmentsBudget changes could lead to different ways of serving the community, according to Isaac Bryan, Executive Director of the UCLA Black Policy Project. Cities may focus more on preventative efforts like education and services for low-income communities."I definitely think there are partnerships to be made and there's opportunity to be had, but that reimagining really first comes with having the resources to dream," said Bryan. "Right now, we don't have that because over half of our budgets, the discretionary funds go to law enforcement and policing."One thing that is likely, whether it be budget or policy changes, is that no two cities can expect to see the same response."Every city is going to be different. San Diego is going to respond differently than Los Angeles and California cities will respond differently than cities in Minnesota," St. George says. 2839

(KGTV) -- A suspect in the freeway shooting death of a San Diego man was arrested following a standoff at a San Diego hotel, California Highway Patrol officials announced Monday.Vincent Dulay Deguzman Jr. faces charges in connection with the June 7 death of 47-year-old San Diego resident Jessie Garcia Sr., CHP officials said.According to the CHP, on June 7, Deguzman and Garcia were in a Kia Altima on southbound Interstate 5 in Irvine when Deguzman, who was behind the wheel, allegedly shot Garcia and then abandoned the rental car south of Culver Drive, where it was found on the shoulder with the body next to the vehicle at around 7:33 a.m.On June 11, CHP investigators identified Deguzman as the suspect in the case and obtained a warrant for his arrest.Investigators collaborated with the San Diego Fugitive Task Force and tracked Deguzman to a Hilton Garden Inn in San Diego.CHP officials said, “Deguzman barricaded himself inside a hotel room and a stand-of ensued.”Deguzman eventually surrendered without incident and was taken into custody.Deguzman was booked into Orange County Jail on suspicion of murder and being held without bail.CHP officials did not release any information on a possible motive in the case. 1234
