A number of Microsoft users reported outages to Microsoft 365 on Monday, including the popular Outlook email service.Microsoft confirmed an outage with Microsoft 365 Monday evening. Microsoft said that a “recent change” appeared to be what caused the issue. But after Microsoft reversed the change, the company said earlier in the evening reversing the change was not successful. Around 9 p.m. ET, the company said that it was seeing improvement in service.“Users would be unable to access Outlook.com, Microsoft Teams including Teams Live Events, and Office.com,” Microsoft said. “Additionally, Power Platform and Dynamics365 properties are affected by this incident. Existing customer sessions are not impacted and any user who is logged in to an existing session would be able to continue their sessions.” 817

A Pennsylvania woman is accused of stabbing an 8-day-old baby last week, claiming the child was created "by the devil," WPXI-TV reported.According to WPXI, Tanishia Fielder, 32, was charged with attempted homicide and aggravated assault after a man reported to police that he and the infant were stabbed by Fielder.Both the man and infant survived the incident, but their exact conditions were not disclosed. Fielder reportedly stabbed the infant near the baby's right eye. Fielder told police that God told her to kill the infant and dismember the body. The police said they found the knife hidden beneath a garbage bin behind the apartment building, WPXI reported.The man involved told police he and Fielder got into an argument earlier in the day and he saw her with a knife. 826

A software flaw is being blamed for showing a positive COVID-19 test result incorrectly for more than two dozen tests. University of Kentucky laboratory scientists say they were inspecting and reviewing raw data from a testing platform when they became concerned about discrepancies in the data. They believe the testing platform, Thermo Fisher, which was authorized for emergency use by the FDA, had a software flaw that might result in false positives.After re-testing the samples using another platform, scientists confirmed that the tests initially reported as positive for COVID-19 were negative. The flaw was only found in one of the four testing platforms that UK's clinical laboratory uses.Every patient who received incorrect results is being notified about the issue. No negative results changed. UK HealthCare also has notified Thermo Fisher Scientific and the FDA."For anyone tested at UK HealthCare, it is important to know that the vast majority of results have not changed," said UK Executive Vice President for Health Affairs Dr. Mark Newman. "Since these very astute employees discovered this issue, we have taken extensive measures to validate each test in question and worked diligently to contact all parties – the vendor, the FDA -- and most importantly, our patients and providers."UK HealthCare says they are working with local health departments and the Kentucky Department of Public Health to correct all data."UK's clinical laboratory has performed more than 30,000 COVID-19 tests since March and only a very small percentage of tests have been affected by this software defect," Newman said. "Anyone who has received test results and has not been contacted this week about re-testing, should be assured their result is correct."This story originally reported by Jordan Mickle on LEX18.com. 1825

A mysterious cigar-shaped object spotted tumbling through our solar system last year may have been an alien spacecraft sent to investigate Earth, astronomers from Harvard University have suggested.The object, nicknamed 'Oumuamua, meaning "a messenger that reaches out from the distant past" in Hawaiian, was first discovered in October 2017 by the Pan-STARRS 1 telescope in Hawaii.Since its discovery, scientists have been at odds to explain its unusual features and precise origins, with researchers first calling it a comet and then an asteroid, before finally deeming it the first of its kind: a new class of "interstellar objects."Now, a new paper by researchers at the Harvard Smithsonian Center for Astrophysics raises the possibility that the elongated dark-red object, which is 10 times as long as it is wide and traveling at speeds of 196,000 mph, might have an "artificial origin.""'Oumuamua may be a fully operational probe sent intentionally to Earth vicinity by an alien civilization," they wrote in the paper, which has been submitted to the Astrophysical Journal Letters.The theory is based on the object's "excess acceleration," or its unexpected boost in speed as it traveled through and ultimately out of our solar system in January 2018."Considering an artificial origin, one possibility is that 'Oumuamua is a light sail, floating in interstellar space as a debris from an advanced technological equipment," wrote the paper's authors, suggesting that the object could be propelled by solar radiation.The paper, written by Abraham Loeb, professor and chair of astronomy, and Shmuel Bialy, a postdoctoral scholar, at the Harvard Smithsonian Center for Astrophysics, points out that comparable light-sails already exist on earth."Light-sails with similar dimensions have been designed and constructed by our own civilization, including the IKAROS project and the Starshot Initiative. The light-sail technology might be abundantly used for transportation of cargos between planets or between stars."In the paper, the pair theorize that the object's high speed and its unusual trajectory could be the result of it no longer being operational."This would account for the various anomalies of 'Oumuamua, such as the unusual geometry inferred from its light-curve, its low thermal emission, suggesting high reflectivity, and its deviation from a Keplerian orbit without any sign of a cometary tail or spin-up torques."'Oumuamua is the first object ever seen in our solar system that is known to have originated elsewhere.At first, astronomers thought the rapidly moving faint light was a regular comet or an asteroid that had originated in our solar system.Comets, in particular, are known to speed-up due to a process known as "outgassing," in which the sun heats up the surface of the icy comet, releasing melted gas. But 'Oumuamua didn't have a "coma," the atmosphere and dust that surrounds comets as they melt.Multiple telescopes focused on the object for three nights to determine what it was before it moved out of sight. 3063

A self-driving vehicle operated by Waymo was involved in a crash in Chandler on Friday afternoon. Helicopter footage from Scripps station KNXV in Phoenix showed significant damage to the self-driving van, as well as a silver sedan, after the collision near Chandler Village Drive and Chandler Boulevard. Minor injuries were reported in the crash.Chandler police said the Waymo van was in autonomous mode with an occupant behind the wheel at the time of the crash, but was not the "violator vehicle."Police spokesman Seth Tyler said it is believed that this is the first Waymo collision in Chandler this year.RELATED: Waymo gives?360-degree?view of what it's like inside self-driving carsThis is the second known self-driving car crash in the Phoenix area in the past two months. An Uber self-driving vehicle hit and killed a?pedestrian in Tempe on March 19.After the March crash, Waymo CEO John Krafcik?said he was confident in his company's technology.In November 2017, Waymo?announced that self-driving cars would be tested in Chandler without someone in the driver's seat. Chandler police told KNXV that an operator was behind the wheel at the time of Friday's collision. KNXV has reached out to Waymo for a comment on the crash.Waymo is subsidiary of Google. The company was founded in 2009.  1359
