BAKERSFIELD, California — Several students from East Bakersfield High School were arrested on Thursday after two fights broke out on campus, according to the Kern High School District.The two fights were unrelated, according to KHSD spokesperson Lisa Krch. Seven students were arrested by KHSD Police.One fight was recorded and the behavior shown is "clearly unacceptable," Krch said.A graphic video has been circulating social media that appears to show a student being jumped and assaulted by a group of other students. The post claims the student suffered a broken neck and was hospitalized, but that has not been confirmed by KHSD. KHSD cannot confirm that video is one of the fights that happened Thursday.KHSD said the incident has been investigated and appropriate student discipline will be implemented. The district cannot comment on student discipline due to FERPA laws protecting the individual right of students, Krch said. 978

As the mystery surrounding the disappearance of Jayme Closs intensifies, one thing has become clear. She vanished from her parents' home moments after they were shot to death."We believe Jayme was in the home at the time of the homicides and we believe she's still in danger," Barron County Sheriff Chris Fitzgerald said Wednesday.Three days after a cryptic 911 call led police to discover the bodies of Jayme's parents in their Wisconsin home, the 13-year-old girl remains missing. Investigators have received more than 400 tips and have not confirmed any credible sightings.But the sheriff said he has a "100 percent expectation that she's alive."An Amber Alert was issued Monday for Jayme and several law enforcement agencies have joined the desperate search. 770

As the COVID-19 pandemic progresses, researchers say it is important to track how the coronavirus mutates because it could affect the efficacy of a vaccine.Like all living cells, viruses evolve their chemical make-up changes. In viruses like the flu, that happens frequently, which is why every year there is a new vaccine to treat whatever strain is expected to circulate. With COVID-19, however, those mutations happen much slower, according to research out of Arizona State University.“One of the things we’re still keeping an eye on is the evolution of this virus because that virus is still around in the community,” said Dr. Efrem Lim, an assistant professor at ASU. “Everyone is coming in blind to this. This is a novel virus. This isn’t something we have seen before.”In March, Arizona State University played host to our country’s fourth COVID-19 case. As soon as it was detected, Dr. Lim started studying how the virus mutates and sent his findings to the World Health Organization. It's something that still continues to this day.“This virus, overall, mutates pretty slowly, which is a good thing,” said Dr. Lim. “However, we can have instances where the virus can have very large, dramatic, mutations, such as deletions in the genome.”While rare, Dr. Lim says those mutations can be significant as it changes how the virus acts inside the body.Currently, scientists are focusing much of their efforts on identifying ways to eliminate the function of the spike protein in COVID-19, as it is the way the virus binds to our cells and infects them (spike proteins are the stalks that protrude from the center of the virus that make it so recognizable).“It is very good news that the virus is not changing rapidly,” said ASU virologist Dr. Brenda Hogue. “We will have to see over time, as the virus continues to circulate, as we put a vaccine into play, whether or not there will be any issues.”Dr. Lim says right now there does not appear to be any issues because the virus mutates slowly, but he adds it could adapt to a vaccine once one begins to circulate.He says more testing needs to be done to determine that, however. 2140

ATLANTA (AP) — A federal judge is permanently blocking Georgia’s 2019 “heartbeat" abortion law, finding that it violates the U.S. Constitution.U.S. District Judge Steve Jones ruled against the state Monday in a lawsuit filed by abortion providers and an advocacy group.Jones had temporarily blocked the law in October, and it never went into effect.The new ruling permanently enjoins the state from ever enforcing House Bill 481.The measure sought to ban abortions once a “detectable human heartbeat” was present, with some limited exceptions.Cardiac activity can be detected by ultrasound as early as six weeks into a pregnancy.Jones found the law violated the 14th Amendment. 685

Attorney General William Barr compared calls for a national lockdown to slavery on Wednesday.Speaking at Hillsdale College, the event's host asked Barr to explain the "constitutional hurdles for forbidding a church from meeting during COVID-19."Barr then launched into a four-minute response where he said a national lockdown would be akin to house arrest.He accused state governors of using their executive powers to stifle citizens and businesses."Other than slavery, which was a different kind of restrain, this is the greatest intrusion on civil liberties in American history," Barr said.The attorney general said he's OK with requiring masks, but not shutting down businesses.The comments came a day after Barr equated prosecutors at the Justice Department to pre-schoolers. 787
