Scientists are reporting that the antibodies people make to fight the new coronavirus do not fade quickly. The new study is the most extensive work yet on the immune system’s response to the virus and is good news for efforts to develop vaccines. The report published Tuesday in the New England Journal of Medicine. It was based on tests on more than 30,000 people in Iceland. It found antibodies lasted for at least four months after diagnosis. The study also found that more severe cases of the coronavirus led to a stronger immune response to the virus."Among recovered persons, antibody levels are higher in older persons and in those more severely affected by SARS-CoV-2 infection," according to the research. Independent experts say if a vaccine can spur production of long-lasting antibodies like that, it gives hope that immunity may not be fleeting. That's what some smaller studies previously suggested.While the research was promising, it did also find that Icelanders are vulnerable to a second wave of the coronavirus even with the number of potentially immune citizens. 1092

SEATTLE (AP) — A U.S. judge on Thursday blocked controversial Postal Service changes that have slowed mail nationwide. The judge called them “a politically motivated attack on the efficiency of the Postal Service” before the November election. READ THE FULL ORDERJudge Stanley Bastian in Yakima, Washington, said he was issuing a nationwide preliminary injunction as sought by 14 states that sued the Trump administration and the U.S. Postal Service. He said the changes created “a substantial possibility many voters will be disenfranchised.”The states challenged the Postal Service’s so-called “leave mail behind” policy, by which trucks have been leaving postal facilities on time whether or not there is more mail to load. They also sought to force the Postal Service to treat election mail as First Class mail.Meanwhile, Postmaster General Louis DeJoy Thursday held a call with the National Association of Secretaries of State (NASS) Election Committee. During the call he affirmed delivering ballots is his organization's top priority between now and Election Day. 1079

SAN FRANCISCO (AP) — Regulators on Friday accused one of California's largest utilities of falsifying safety documents for natural gas pipelines for years following its criminal conviction and multimillion-dollar fine for a pipeline explosion that killed eight people near San Francisco.The California Public Utilities Commission said an investigation by its safety and enforcement division found Pacific Gas & Electric Co. lacked enough employees to fulfill requests to find and mark natural gas pipelines.Because of the staff shortage, PG&E pressured supervisors and locators to complete the work, leading staff to falsify data from 2012 to 2017, regulators said. The company "had common knowledge among its supervisors that locators falsified data," the commission said."Utility falsification of safety related records is a serious violation of law and diminishes our trust in the utility's reports on their progress," commission President Michael Picker said in a statement. "These findings are another example of why we are investigating PG&E's safety culture."PG&E said it has hired more employees and improved its pipeline tracking system."We're committed to accurate and thorough reporting and record-keeping, and we didn't live up to that commitment in this case," utility spokesman Matt Nauman said in a statement.A U.S. judge fined the utility million after it was convicted of six felony charges for failing to properly maintain a natural gas pipeline that exploded in 2010 and wiped out a neighborhood in suburban San Bruno. Regulators also fined PG&E .6 billion for the blast."This is the period immediately following the 2010 San Bruno gas explosion and fire that resulted in eight fatalities, numerous injuries and damage to property," the commission said in its report. "This commission would expect that after such a tragedy, caused by multiple proven violations of law, PG&E would have sought to vigorously enhance and increase its effectiveness in all aspects of its gas safety."The investigation was forwarded Thursday to a judge, who will hear testimony on the findings and will allow PG&E to provide evidence that it didn't violate safety laws.The utility that provides service to millions of people throughout Northern California also is under scrutiny for its role in igniting wildfires. The California Department of Forestry and Fire Protection found that PG&E equipment was responsible for starting 16 wildfires last year.While a cause has not yet been determined for the massive fire that wiped out the town of Paradise and killed at least 86 people last month, PG&E equipment is being scrutinized. A number of victims have sued the utility, alleging negligence. 2739
