Unidentified flying objects the size of sports utility vehicles have been spotted over parts of the northeastern US, leading to investigations by law enforcement and the FBI. The Federal Aviation Administration has temporarily banned drone flights over president-elect Donald Trump's golf club and a major military research and manufacturing facility in New Jersey in response to the mysterious lights in the sky. Videos of the flying objects over New Jersey, New York, and Pennsylvania have sparked speculation about whether they are alien ships, spy balloons, or unmanned drones. New Jersey officials have confirmed the sightings and assured the public that the FBI and Homeland Security are on the case, urging the public to report any information to the FBI and upload videos to tips[.]fbi[.]gov. County and local law enforcement agencies have acknowledged the public's concern and stated they will continue to monitor and investigate the drone activity in close cooperation with federal partners. The New Jersey governor and other government agencies have also been actively monitoring the situation, reassuring the public that there is no known threat at this time. The FAA has issued temporary flight restrictions prohibiting drone flights over certain areas, and they are investigating all reports of unauthorized drone operations. The Register will update the story with more information as it becomes available.

A new theoretical model, reminiscent of the famous Drake Equation, has been developed by astrophysicists at Durham University to estimate the probability of intelligent life emerging in our Universe and hypothetical others. The model focuses on the conditions created by the Universe's expansion acceleration due to dark energy and the number of stars formed. The research, published in Monthly Notices of the Royal Astronomical Society, suggests that our Universe may not possess the most conducive properties for the emergence of intelligent life, as it experiences lower star formation efficiency compared to hypothetical universes. Lead researcher Dr. Daniele Sorini explains that understanding dark energy's impact on our Universe is crucial and that a significantly higher dark energy density could still be compatible with life, suggesting our Universe may not be the most likely for the emergence of intelligent life. This model opens the door to exploring the emergence of life across different universes and reinterpreting fundamental questions about our own Universe.
