The Department of Defense announced on Friday the formation of the Unidentified Aerial Phenomena Task Force, which will be tasked with looking into reports of UFOs.The Pentagon says that task force’s mission is to detect, analyze and catalog unidentified aerial phenomena, better known as UFOs, that could potentially pose a threat to U.S. national security.“As DOD has stated previously, the safety of our personnel and the security of our operations are of paramount concern,” the Department of Defense said. “The Department of Defense and the military departments take any incursions by unauthorized aircraft into our training ranges or designated airspace very seriously and examine each report. This includes examinations of incursions that are initially reported as UAP when the observer cannot immediately identify what he or she is observing.”Sen. Marco Rubio confirmed the formation of the task force last month in an interview with Miami’s WFOR-TV."We have things flying over our military bases and places where we are conducting military exercises, and we don't know what it is and it isn't ours, so that's a legitimate question to ask,"Rubio said.In April, the Pentagon released videos of “unidentified aerial phenomena” captured by Navy pilots. One of the videos was from 2004, while another two were from 2015.“After a thorough review, the department has determined that the authorized release of these unclassified videos does not reveal any sensitive capabilities or systems, and does not impinge on any subsequent investigations of military air space incursions by unidentified aerial phenomena,” the Pentagon said in April. “DOD is releasing the videos in order to clear up any misconceptions by the public on whether or not the footage that has been circulating was real, or whether or not there is more to the videos.” 1846

The cost of sending a letter might be going up next year.On Friday, the United States Postal Service issued a press release stating that they had filed notice with the Postal Regulatory Commission (PRC) about its plan to increase prices.The new proposal would raise the price of first-class mail by 1.8% and 1.5% for other categories, the agency said.The additional ounce price for a single-piece letter would increase to 20 cents, the price for a metered mail 1-ounce would increase to 51 cents, and the cost of sending a postcard would increase to 36 cents.Items that will remain unchanged are the single-piece 1-ounce flat prices, which will stay , and the forever stamp will stay at 55 cents.The Postal Service Board of Directors believes the price increase will provide revenue for the agency and keep them competitive.The price increase will take effect on Jan. 24 after a review by the PRC. 907

The CDC is considering changing its quarantine guidelines for those who have been in close contact with someone who is infected with the coronavirus.Currently, those who have been in close contact with someone infected with the virus would be advised to quarantine for 14 days. Possible new guidance would shorten the quarantine period to 10 days. At the end of the 10-day period, a test would be need to end quarantine.In an interview with CNN’s Wolf Blitzer, Adm. Brett Giroir, the assistant secretary for health at Health and Human Services, explains why a 10-day quarantine might be more effective at getting more compliance with the guidance."People are much more likely to listen to a 10-day quarantine than they are a 14-day quarantine,” Giroir said. “If we can shorten it safely with most risk because we have a quarantine plus a test, we have a lot of tests available now, that might improve our public health responses.”Giroir stressed that final guidelines have not been approved, and the current guidance still calls for a 14-day quarantine.“It's not an announcement that is happening but we are reviewing it and the CDC team is modeling it and looking at data every day,” Giroir said.“And it may change or it may not. Just depends on where the data and the evidence wind up." According to the CDC, a person can become infected with the virus up to 14 days following exposure. But researchers say most illnesses begin five to seven days after COVID-19 exposure.A close contact is considered someone who is within 6 feet of someone with the virus for a period of 15 minutes or more over the course of a day. 1626

The first cruise in the Caribbean since the start of the pandemic is reporting a COVID-19 case.A passenger aboard SeaDream Yacht Club’s SeaDream 1 received a preliminary positive COVID-19 test.According to passengers, the captain informed them about the preliminary positive test over the ship’s intercom system while they were anchored off the coast of Grenadines.The vessel is now headed back to Barbados, where it is based.The SeaDream is carrying 53 passengers and 66 crew, with the majority of passengers hailing from the U.S. according to Sue Bryant, who is aboard the ship and is a cruise editor for The Times and The Sunday Times in Britain.The SeaDream is the first vessel to resume sailing in the Caribbean since earlier this year when coronavirus pandemic concerns docked the cruise industry following high profile infections.Passengers were tested both in advance of traveling, before boarding, and again a few days into the trip.The SeaDream has a capacity of about 110 guests and 95 crewmembers. It also sails outside of U.S. waters. This puts it below the 250 guests threshold and outside the area under the CDC’s orders about cruising. 1159

The excitement of two COVID-19 vaccines with more than 90 percent efficacy is undeniable.In November, both Pfizer and Moderna announced its scientists had developed vaccines with efficacy at or near 95 percent, but scientists are warning these vaccines are not the "silver bullet" to ending the pandemic.“We don’t want to give the public the impression that there’s an emergency use authorization and these vaccines become available in a small amount in December and we can go back to our pre-pandemic behavior,” said William Moss, executive director of the International Vaccine Access Center at Johns Hopkins.In June, the FDA released its vaccine guidelines, saying it would consider emergency use authorization for any vaccine testing with at least 50 percent effectiveness, so there is a reason for celebration, according to Moss, but only after certain questions about the vaccine are answered.Dr. Anthony Fauci has said the initial vaccines will prevent symptoms in those who become infected, rather than kill the virus itself. Moss says that means immunized people might be able to spread COVID-19 to others.He also wonders how long immunization will last. One year? Three years? Will booster doses be needed? They're all careful considerations that will only emerge once one is put into play, according to Moss.“It’s obviously tragic that the [COVID] cases are occurring that quickly, but it does help a vaccine trial because otherwise you just have to wait that much longer for samples to come in,” said Moss.The vaccine process has innovated how scientists and researchers approach these types of situations, however, according to Moss.In traditional vaccines, a small dose of the virus is injected into the body so the immune system can create antibodies. In the COVID-19 vaccine, though, both Moderna and Pfizer have used what is called messenger RNA (mRNA) where the virus’ genetic code is injected into the body so it can instruct cells on what antibodies to produce. Scientists say this way is faster, safer, and can create a stronger immune response as people are not exposed to the virus.“I suspect that if this all goes well and these vaccines are safe and continue to demonstrate 90 to 95 percent efficacy, we’re going to see other vaccines of a similar type,” said Moss. 2298
