Bulked-up, mutant “mighty mice” held onto their muscle during a monthlong stay at the International Space Station, returning to Earth with ripped bodybuilder physiques, scientists reported Monday.The findings hold promise for preventing muscle and bone loss in astronauts on prolonged space trips like Mars missions, as well as people on Earth who are confined to bed or need wheelchairs.A research team led by Dr. Se-Jin Lee of the Jackson Laboratory in Connecticut sent 40 young female black mice to the space station in December, launching aboard a SpaceX rocket.In a paper published in the Proceedings of the National Academy of Sciences, Lee said the 24 regular untreated mice lost considerable muscle and bone mass in weightlessness as expected — up to 18%.But the eight genetically engineered “mighty mice” launched with double the muscle maintained their bulk. Their muscles appeared to be comparable to similar “mighty mice” that stayed behind at NASA’s Kennedy Space Center.In addition, eight normal mice that received “mighty mouse” treatment in space returned to Earth with dramatically bigger muscles. The treatment involves blocking a pair of proteins that typically limit muscle mass.A SpaceX capsule brought all 40 mice back in good condition, parachuting into the Pacific off the California coast in January. Some of the ordinary mice were injected with the “mighty mice” drug after returning and quickly built up more muscle than their untreated companions, Lee said.The scientists completed the experiment just as the coronavirus was hitting the U.S.“The only silver lining of COVID is that we had time to write it up very intensively” and submit the results for publication, said Dr. Emily Germain-Lee of Connecticut Children’s Medical Center, Lee’s wife who also took part in the study. Both are affiliated with the University of Connecticut.While encouraged by their findings, the couple said much more work needs to be done before testing the drug on people to build up muscle and bone, without serious side effects.“We’re years away. But that’s how everything is when you go from mouse to human studies,” Germain-Lee said.Lee said the experiment pointed out other molecules and signaling pathways worth investigating — “an embarrassment of riches ... so many things we’d like to pursue.” His next step: possibly sending more “mighty mice” to the space station for an even longer stay.Three NASA astronauts looked after the space mice, performing body scans and injections: Christina Koch and Jessica Meir, who performed the first all-female spacewalk last fall, and Andrew Morgan. They are listed as co-authors.___The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.

CARLSBAD, Calif. (KGTV) – It opened with much fanfare back in September, but after a two week period of cancellations February, Carlsbad-based airline, Cal Jet was still dealing with setbacks in early March.“I can’t say that it didn’t [suffer],” said Cal Jet’s President, George Wozniak of their reputation.On Friday, he stood on the tarmac at McClellan-Palomar Airport, personally apologizing to travelers boarding a plane at 4:15 p.m. that had been originally scheduled to leave at 9 a.m.Wozniak said the passengers had been notified of the delay earlier in the day. The plane had experienced mechanical problems the night before and had to fly to Arizona last night for repairs.The delays come after the airline canceled nearly two weeks of flights, beginning just before President’s Day weekend.Wozniak said the plane they use, which is owned by Elite Air, had also been booked by NCAA basketball teams. “It was either a crew or aircraft scheduling problem, where if they had one pilot get ill and not show up, it could throw the whole thing off,” described Wozniak.They could theoretically still use it, but rather than risk more abrupt cancellations, he decided to clear the schedule until they could get the plane back full time.“It was not an easy decision to make,” said Wozniak.Cal Jet’s Yelp page says why. After the cancellations, the page was flooded with one-star reviews. “If I could give zero stars... or even a negative star review, I would confidently put this airline in that category,” wrote Rachel L.Another reviewer, Justin K. said his return flight was canceled last minute, forcing him and his pregnant wife to find last-minute accommodations back to Carlsbad.We finally decided to rent a car and drive 5+ hours with traffic, with my pregnant wife, stopping every couple hours for her to walk around for medical reasons, making the drive even longer.Wozniak said all the customers received refunds and a 0 flight voucher.He said they plan on expanding their coverage to several other cities later this year, which will include new planes as well.“We feel very confident going forward we’ll have the extra crew and airplanes necessary to fulfill that travel mission for these people without any real problems.” 2254

Buoyed by Pfizer's promising update on a potential COVID-19 vaccine and Saturday's presidential election call, U.S. markets skyrocketed on Monday morning as investors eyed the light at the end of the pandemic tunnel.The Dow Jones Industrial Average jumped more than 1,300 points in the moments after trading opened, an increase of about 5%. The NASDAQ saw an increase of about 150 points, or about 1%, while the S&P 500 jumped 120 points or about 3%.The Dow closed Monday at 29,157, which is up nearly 3% from Friday's close. The Dow has almost made a full recovery from its February 12 high point of 29,551. The jump came hours after Pfizer announced that is COVID-19 vaccine candidate has been 90% effective so far in promoting protection against the virus in Phase 3 trials. While the announcement does not mean a vaccine is imminent — in fact, it could be more than six months before most Americans will have a chance to get the vaccine — it does mean Pfizer is on track to apply for Emergency Usa Authorization in the coming months.Pfizer's stock exploded in early trading Monday, jumping about 3 points or an increase of 8%.Monday continues what has been a roller coaster 2020 for American markets. After the pandemic led to historic drops in February and March, markets have rallied in recent months and erased most of those losses. Monday's gains have so fae wiped out loses from October, which were caused by Congress' decision not to pursue more COVID-19 stimulus before the end of the current legislative term. 1533

CAMPO, Calif. — Campo Elementary School students were forced off a school bus after a man stormed onto the bus armed with two knives.Matthew Barker, 37, of Campo, was arrested by the San Diego Sheriff's Department after he boarded the bus packed with students at an apartment complex on Friday around 8:30 a.m., according to Mountain Empire Unified School District superintendent Kathy Granger.Officials said Barker entered the bus and was immediately told by the driver to leave. Barker ignored the driver and continued up the stairs and toward students before the driver got in front of him.As Barker tried to push past the driver, a grandmother of one of the students saw what was happening and got onto the bus to help the driver, officials said. That's when Barker reportedly pulled out a knife and swung at the driver.As the driver and grandmother struggled with Barker, an older student ushered students to the back exit of the school bus and called to nearby parents for help. The students were able to exit out of the bus unharmed.Another good Samaritan then got on the bus, at which point Barker turned the knife on himself, according to the Sheriff's Department. The Samaritan pried the knife away from Barker and pulled him off the bus as deputies arrived.Barker has been charged with felony assault. Authorities are investigating the incident and believes drugs were a factor in the attack.The bus driver and Samaritans were not injured."We take safety very seriously and want to assure you our buses remain a safe form of transportation for getting children to and from school," Granger said in a statement. 1669

CHICAGO, Ill. – The City of Chicago will soon implement under another stay-at-home advisory as it seeks to slow the spread of the coronavirus.The city’s mayor, Lori Lightfoot, announced Thursday that the advisory will go into effect on Monday, Nov. 16 at 6 a.m.Lightfoot says the advisory will call on the people of Chicago to stay at home unless for essential reasons, stop having guests over – including relatives they don’t live with, avoid non-essential travel, and cancel “traditional” Thanksgiving plans."Residents are advised to only leave home to go to work or school, or for essential needs such as seeking medical care, going to the grocery store or pharmacy, picking up food, or receiving deliveries," the city wrote.The city says the advisory will remain in place for 30 days or until the commissioner of health, Dr. Allison Arwady, determines a change in the guidance is appropriate.The new advisory comes as the city and many parts of the country experience the highest coronavirus case rates since the pandemic began. Lightfoot says data shows the city is seeing an average of at least 1,900 cases per day."If we continue on the path we’re on and don’t step up to do the things we know work, we estimate we will lose 1,000 more Chicagoans to this virus by the end of the year," said the mayor.Lightfoot says the stay-at-home advisory is part of a new strategy called “Protect Chicago,” which she describes as a comprehensive effort that includes new regulatory actions, neighborhood street-level activations and citywide public awareness.Watch the mayor's announcement below: 1598
