More than 136,000 people were diagnosed with COVID-19 in the U.S. on Tuesday according to a Johns Hopkins database, marking the fourth time this month that the country has broken the record for confirmed COVID-19 cases in a single day.Tuesday also marked the deadliest day of the pandemic in several months. More than 1,400 Americans died of the virus on Tuesday, the most recorded in a single day since 1,500 Americans died of the virus on Aug. 12.Tuesday's tally shattered the previous record of 128,000, which was set on Saturday. The mark continues a disturbing and troubling trend as health officials suspect spread will only increase as social gatherings move indoors during winter months.About a million Americans have contracted COVID-19 in the first 10 days of November.While the exploding spread rate is concerning on its own, several states across the country report that they are nearing full hospital capacity as severe cases of the virus increase.North Dakota Gov. Doug Burgum said earlier this week that hospitals have already reached operating capacity and fears that facilities could be pushed past their capabilities in the coming months.In Iowa, the state's largest city is also nearing hospital capacity as available beds dwindle.More than 10.2 million Americans have contracted virus, and 239,000 have died since the virus reached the U.S. in February. Both figures lead all other countries around the world. 1437

Mystery is no stranger to the Great Pyramid of Giza. For centuries, scientists and archaeologists have probed inside the largest and oldest of Egypt's famed pyramids.But until now none had stumbled upon a 30-meter-long space hidden within its limestone and granite walls.An international group of scientists has used modern technology to visualize the inside of the pyramid, according to an article published Thursday in the journal Nature. 448

Moderna is asking American regulators to allow emergency use of its COVID-19 vaccine. It says its final results show the vaccine is 94% effective.The drug maker says it had 196 COVID-19 cases so far in its study. It says 185 of those participants received the placebo, while 11 got the real vaccine. The 30 people who became seriously ill in the trial didn't get the vaccine.FDA advisors are expected to look at all the evidence on December 17. They'll be checking out Pfizer’s vaccine on December 10.Pfizer and Moderna's success with their COVID-19 trials could impact how vaccines are made in the future.It has to do with how they work. They use what's called messenger RNA (mRNA) technology. The virus' genetic code is injected into the body so it can instruct cells on what antibodies to produce.It hasn't been approved to be used in a commercial vaccine before.“In the future, it's clearly going to be tough to beat RNA vaccines for speed and that's a wonderful thing. Just this demonstration of how incredibly fast they can move has been great. How effective they can be, I think will depend on a particular disease,” said Shane Crotty, Ph.D. with the La Jolla Institute for Immunology.Crotty says the narrowest application for this vaccine technology in the future is a similar situation where there's a new emerging virus."The mRNA vaccine has been tried for other infectious diseases and they have been investigated for cancer. There's a whole area of trying to vaccine against cancer, which has kind of been an elusive target,” said Dr. Alessandro Sette with the La Jolla Institute for Immunology.A big question with an mRNA vaccine is how long its protection will last. While there is encouraging findings, there's no historical comparison to look at.A big thing experts say has helped with a vaccine is there has been a lot of money put towards manufacturing before we even knew it would work.Click here to learn more about mRNA vaccines. 1958

MILWAUKEE -- Six cars were damaged Friday when light poles fell across traffic lanes on I-43 near Milwaukee.According to the Milwaukee County Sheriff's Office, the driver of a red pick-up truck heading northbound hit both of the light poles in the median just before 3:30 p.m. A witness at a law firm off Hampton Avenue said she saw the truck drive up onto the median and hit one pole, before continuing on to hit a second. "Unfortunately one of them kind of struck the side of the car, put a hole in the door, took a mirror out," said Jim Lovering, whose daughter called him after swerving to avoid the two poles.Lovering's 7-month-old grandson was also in the car. "Just missed the windshield, which was a blessing," said Lovering. The camera caught deputies taking away the driver of the red truck in handcuffs. Authorities have not yet released any information confirming an arrest, or possible charges. The accident caused backups for miles during rush hour, as crews worked to remove the poles from the roadway. No one in any of the cars was injured. "It was just nice that she had the space to maneuver and without hitting anybody else or causing any further damage," said Lovering. "It could be potentially you know a serious accident. Thank God it didn't happen."  1341
