BATON ROUGE, La. — Louisiana officials have announced two deaths from Hurricane Delta.Gov. John Bel Edwards said Sunday an 86-year-old man from St. Martin Parish died in a fire that started after he refueled a power generator in a shed. The governor said it didn't appear that the man had let the generator cool down before refueling it.Louisiana officials are also attributing the death of a 70-year-old woman to the hurricane. State officials said the Iberia Parish woman died in a fire caused by a natural gas leak.Earlier Sunday, officials in Florida said a 19-year-old tourist from Illinois drowned after being caught in a rip current unleashed by the remnants of Delta in the Gulf Coast.Delta made landfall Friday evening in southwest Louisiana as a Category 2 hurricane and then began weakening quickly over land. It came weeks after Hurricane Laura battered the same region.Laura claimed 32 lives, though only seven of the deaths came the day that the hurricane struck. Many others were caused by carbon monoxide poisoning from generators.As of Sunday, utility crews in Louisiana are scrambling to restore power and residents in the besieged southwest part of the state are vowing to rebuild in the wake of Delta. 1229

BERLIN — The United States has formally left the Paris Agreement, a global pact forged five years ago to avert the threat of catastrophic climate change. The move was long threatened by U.S. President Donald Trump and triggered by his administration a year ago. It further isolates the United States in the world but has no immediate impact on international efforts to curb global warming. Some 189 countries remain committed to the 2015 accord, which aims to keep the increase in average temperatures worldwide “well below” 2 degrees Celsius compared to pre-industrial levels. Scientists say that any rise beyond 2 degrees Celsius could have a devastating impact on large parts of the world, raising sea levels, stoking tropical storms and worsening droughts and floods. 779

BOSTON (AP) -- Harvard University and the Massachusetts Institute of Technology filed a federal lawsuit Wednesday challenging the Trump administration's decision to bar international students from staying in the U.S. if they take classes online this fall.The lawsuit, filed in Boston's federal court, seeks to prevent federal immigration authorities from enforcing the rule. The universities contend that the directive violates the Administrative Procedures Act because officials failed to offer a reasonable basis justifying the policy.The Trump administration did not respond to media requests for comment.U.S. Immigration and Customs Enforcement notified colleges Monday that international students will be forced to leave the U.S. or transfer if their schools operate entirely online this fall. 806

BRUCE TOWNSHIP, Michigan — A company that supplies equipment to the University Hospitals fertility center said its storage tank did not malfunction. “The early stages of our investigation into this unfortunate incident indicate it was the result of human error,” Custom Biogenic Systems said in a detailed statement sent to E.W. Scripps Co. TV station WEWS in Cleveland, Ohio.In a letter to patients on March 26, University Hospitals said that a remote alarm system on a storage tank that was designed to alert a University Hospitals employee to changes like temperature swings was turned off. UH said that on the evening of Saturday, March 3, the temperature inside the tank, which contained thousands of eggs and embryos, rose. UH does not know when the alarm was turned off. During the period when the alarm was off, UH said it had been experiencing “difficulty with what is called the liquid nitrogen automatic fill on the storage tank” for “several weeks.” Liquid nitrogen is added to the storage tank to keep specimens frozen, and it can be added manually or automatically. According to UH, “We had been working with the tank manufacturer who had previously provided instructions on the necessary maintenance to ‘thaw’ the storage tank to correct this difficulty. To do that required transferring all specimens to an extra storage tank previously provided by the manufacturer. This process takes several weeks, and had begun when this event occurred, though no eggs or embryos had yet been moved to the extra tank.”Custom Biogenic Systems, of Bruce Township, Mich., says the extra tank was available to UH on Aug. 15, 2017, UH finalized its arrangements for delivery of the tank on Oct. 27, 2017, and the tank was delivered on Nov. 2, 2017. That’s almost four months to the day before 950 UH patients lost 4,000 eggs and embryos in an event the hospital would later call “catastrophic." With the automatic fill not working on the original tank, UH added liquid nitrogen to the tank manually. This was done by connecting the storage tank with a line to a tank of liquid nitrogen from the Embryology Lab. But, according to UH, “For several days prior to the weekend in question, a manual fill could not be done using the line in the Embryology Lab because there were no liquid nitrogen tanks available. So, containers of liquid nitrogen were obtained from the Andrology Lab. Those containers were then manually poured into the top of the tank, while amounts of liquid nitrogen and temperature were monitored.” Custom Biogenic Systems says its tank is not designed to be filled by liquid nitrogen poured into the top of the tank.The company said its product manual states:  2744
