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.

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
