The Department of Homeland Security has suspended all flights between the U.S. and Venezuela.Acting Secretary of Homeland Security Kevin McAleenan determined that conditions in Venezuela threaten the safety and security of passengers, aircraft, and crew, requiring an immediate suspension of all commercial passenger and cargo flights between the United States and Venezuela. The Secretary of State has approved flight suspension and the Secretary of Transportation has implemented the determination.The move is based on ongoing political instability and increased tensions in the country, and associated inadvertent risk to flight operations, a press release said.According to DHS, if and when the conditions in Venezuela change, and if in the public interest, the Secretaries will revisit this determination. Until then, the flight suspension will remain in effect indefinitely. 892

TEHRAN, Iran (AP) — Iran's government says 12 people have died nationwide from COVID-19, commonly known as coronavirus, and it has rejected claims of a much higher death toll by a lawmaker from the city of Qom that has been at the epicenter of the virus in the country. The conflicting reports raised questions about the Iranian government’s transparency concerning the scale of the outbreak. Iran's Health Ministry said total infections have risen to 61 while deaths stood at 12. However, a lawmaker from Qom was quoted by a semi-official news agency as saying the death toll was 50. Even with the lower toll of 12, the number of deaths compared to the number of confirmed infections is higher in Iran than in any other country.The 745

The CDC said Friday that no one e-cigarette or vaping product has led to an outbreak of a severe lung disease that is sickening users across the country.According to a CDC press release,215 e-cigarette and vape users in 25 states have been sicked by a serious lung disease since August. That number does not include cases still under investigation.At least three people have died as a result of the disease.The Washington Post reports that there have been 450 cases of serious lung disease in 33 states, dating back to early summer.The CDC reported Friday that of all those sickened by the lung disease, many — but not all — reported using vape products containing THC. The agency did note that there were also some reports of patients using both THC and nicotine products, and a smaller group of patients that were only using nicotine products.The CDC's update came a day after the New York State Department of Health said it believes 949

That black hole you've seen everywhere now has a name.It's been christened Powehi — a Hawaiian phrase referring to an "embellished dark source of unending creation."The groundbreaking, first-ever photograph of a black hole was published around the world when it was unveiled on Wednesday, captivating viewers and providing the only direct visual evidence that these regions of spacetime exist.The responsibility of finding it a name fell to Larry Kimura, a Hawaiian language professor at the University of Hawaii at Hilo, who was approached by astronomers involved with the project. Two of the eight telescopes used to capture the photograph are located in Hawaii.Powehi was chosen for its roots in the Kumulipo, an 18th-century Hawaiian chant that describes a creation story.It puts together two terms from the chant: Po, meaning profound dark source of unending creation, and wehi (or wehiwehi) which is one of the several ways that po is described in the chant."It is awesome that we, as Hawaiians today, are able to connect to an identity from long ago, as chanted in the 2,102 lines of the Kumulipo, and bring forward this precious inheritance for our lives today," Kimura said in a statement."To have the privilege of giving a Hawaiian name to the very first scientific confirmation of a black hole is very meaningful to me and my Hawaiian lineage that comes from po," he added. "I hope we are able to continue naming future black holes from Hawaii astronomy according to the Kumulipo."Powehi was captured by the Event Horizon Telescope, a project that connected eight telescopes around the world.The supermassive black hole and its shadow, at the center of a galaxy known as M87, were photographed back in April 2017, but the results were only revealed on Wednesday."We have seen what we thought was unseeable," said Sheperd Doeleman, director of the Event Horizon Telescope Collaboration, unveiling the historic snap. "We have seen and taken a picture of a black hole."More than 200 researchers were involved in the project, and they had worked for more than a decade to capture the image. The project is named after the event horizon, the proposed boundary around a black hole that represents the point of no return where no light or radiation can escape.The telescope array collected 5,000 trillion bytes of data over two weeks, which was processed through supercomputers so that the scientists could retrieve the images."Powehi, as a name, is so perfect, because it provides real truths about the image of a black hole that we see," Jessica Dempsey of the James Clerk Maxwell Telescope, said in 2617

The Massachusetts Institute of Technology is reviewing about 0,000 it received from foundations controlled by accused sex trafficker Jeffrey Epstein, MIT's president said.The school also will donate that amount to a charity benefiting Epstein's victims or other sexual abuse victims, President L. Rafael Reif said in an email.The review will focus on the facts around the donations, made over 20 years, and how the school handles contributions and can improve that process, Reif said.Epstein was awaiting trial on charges of sex trafficking involving underage girls when he killed himself by hanging in a New York jail cell this month."I offer a profound and humble apology" to the victims on behalf of the administration, Reif said. "With hindsight, we recognize with shame and distress that we allowed MIT to contribute to the elevation of his reputation, which in turn served to distract from his horrifying acts. No apology can undo that."The donations went to the MIT Media Lab or Seth Lloyd, a professor of mechanical engineering, according to Reif's email. 1078
