The U.S. has now surpassed 17 million confirmed cases of COVID-19 and has yet again recorded more than 1 million cases of the virus in less than a week, according to a database kept by Johns Hopkins University.The U.S. reached the 16 million case threshold over the weekend. According to the COVID Tracking Project, the country is averaging more than 200,000 new cases of the virus every day, putting it on pace to record 1 million cases every five days.Since Oct. 30, the U.S. has recorded more than 8 million cases of COVID-19 — a number that represents 47% of all cases recorded since the virus reached the U.S. in January. The U.S. is currently in the midst of the most deadly stretch of the pandemic to date. The country surpassed 300,000 deaths linked to the virus on Monday. Since then, nearly 8,000 more people have died of the disease.The COVID Tracking Project reports that the U.S. has averaged more than 2,500 deaths every for the last week — and that number will likely increase in the weeks to come. The COVID Tracking Project also reports that record numbers of Americans are battling the virus in a hospital. The group says more than 113,000 people are currently hospitalized with the virus, leading many health care facilities — particularly those in rural areas — to reach maximum capacity levels.Spikes in COVID-19 typically trail behind spikes in cases and hospitalizations, meaning death totals will likely only increase in the weeks to come. 1481

The Wake Forest Institute for Regenerative Medicine says it has a new use for its bioprinting system. In the past they've 3D printed normal-size organs and tissues in hopes of someday implanting them in patients.For the coronavirus, the lab is creating organs using human cells that can be as small as a pinhead. They're focusing on the organs most likely to be infected by the disease. like the lungs.“And so we've been playing with a number of agents to, on both prongs what can make it more infective, what can make it less infective to try to sort this out for the future,” Anthony Atala, director for the institute said.Atala says he hopes the system will help in testing drugs before they hit the market.Drug companies do extensive testing and clinical trials in people before releasing a new medication.Atala says sometimes those companies find no serious side effects, but then years later, discover that it's toxic to patients taking it. Atala says testing a drug using the bioprinting system can tell if a drug is toxic in weeks instead of after years on the market.“Even though we've used the tool extensively for toxicity testing, it's also a tool that can be used for screening,” Atala said. “So we can test agents that are currently being considered for testing against COVID and test the efficacy of the treatment on miniature human organs made up of normal cells”To be clear, Atala said drug tests on 3D printer organs are not meant to replace clinical trials in humans, be are an added step to better predict what will happen in those trials. 1567

The Supreme Court on Tuesday ruled that the Trump administration can end census field operations early, in a blow to efforts to make sure minorities and hard-to-enumerate communities are properly counted in the crucial once-a-decade tally.The decision was not a total loss for plaintiffs in a lawsuit challenging the administration’s decision to end the count early. They managed to get nearly two extra weeks of counting people as the case made its way through the courts.However, the ruling increased the chances of the Trump administration retaining control of the process that decides how many congressional seats each state gets — and by extension how much voting power each state has.The Supreme Court justices’ ruling came as the nation’s largest association of statisticians, and even the U.S. Census Bureau’s own census takers and partners, have been raising questions about the quality of the data being gathered — numbers that are used to determine how much federal funding and how many congressional seats are allotted to states.After the Supreme Court’s decision, the Census Bureau said field operations would end on Thursday.At issue was a request by the Trump administration that the Supreme Court suspend a lower court’s order extending the 2020 census through the end of October following delays caused by the pandemic. The Trump administration argued that the head count needed to end immediately to give the bureau time to meet a year-end deadline. Congress requires the bureau to turn in by Dec. 31 the figures used to decide the states’ congressional seats — a process known as apportionment.By sticking to the deadline, the Trump administration would end up controlling the numbers used for the apportionment, no matter who wins next month’s presidential election.In a statement, House Speaker Nancy Pelosi called the Supreme Court’s decision “regrettable and disappointing,” and said the administration’s actions “threaten to politically and financially exclude many in America’s most vulnerable communities from our democracy.”Associate Justice Sonia Sotomayor dissented from the high court’s decision, saying “respondents will suffer substantial injury if the Bureau is permitted to sacrifice accuracy for expediency.”The Supreme Court ruling came in response to a lawsuit by a coalition of local governments and civil rights groups, arguing that minorities and others in hard-to-count communities would be missed if the census ended early. They said the schedule was cut short to accommodate a July order from President Donald Trump that would exclude people in the country illegally from being counted in the numbers used for apportionment.Opponents of the order said it followed the strategy of the late Republican redistricting guru, Thomas Hofeller, who had advocated using voting-age citizens instead of the total population when it came to drawing legislative seats since that would favor Republicans and non-Hispanic whites.Last month, U.S. District Judge Lucy Koh in San Jose, California sided with the plaintiffs and issued an injunction suspending a Sept. 30 deadline for finishing the 2020 census and a Dec. 31 deadline for submitting the apportionment numbers. That caused the deadlines to revert back to a previous Census Bureau plan that had field operations ending Oct. 31 and the reporting of apportionment figures at the end of April 2021.When the Census Bureau, and the Commerce Department, which oversees the statistical agency, picked an Oct. 5 end date, Koh struck that down too, accusing officials of “lurching from one hasty, unexplained plan to the next ... and undermining the credibility of the Census Bureau and the 2020 Census.”An appellate court panel upheld Koh’s order allowing the census to continue through October but struck down the part that suspended the Dec. 31 deadline for turning in apportionment numbers. The panel of three appellate judges said that just because the year-end deadline is impossible to meet doesn’t mean the court should require the Census Bureau to miss it.The plaintiffs said the ruling against them was not a total loss, as millions more people were counted during the extra two weeks.“Every day has mattered, and the Supreme Court’s order staying the preliminary injunction does not erase the tremendous progress that has been made as a result of the district court’s rulings,” said Melissa Sherry, one of the attorneys for the coalition.Besides deciding how many congressional seats each state gets, the census helps determine how .5 trillion in federal funding is distributed each year.San Jose Mayor Sam Liccardo said that his city lost 0 million in federal funding over the decade following the 2010 census, and he feared it would lose more this time around. The California city was one of the plaintiffs in the lawsuit.“A census count delayed is justice denied,” Liccardo said.With plans for the count hampered by the pandemic, the Census Bureau in April had proposed extending the deadline for finishing the count from the end of July to the end of October, and pushing the apportionment deadline from Dec. 31 to next April. The proposal to extend the apportionment deadline passed the Democratic-controlled House, but the Republican-controlled Senate didn’t take up the request. Then, in late July and early August, bureau officials shortened the count schedule by a month so that it would finish at the end of September.The Senate Republicans’ inaction coincided with Trump’s order directing the Census Bureau to have the apportionment count exclude people who are in the country illegally. The order was later ruled unlawful by a panel of three district judges in New York, but the Trump administration appealed that case to the Supreme Court.The Supreme Court decision comes as a report by the the American Statistical Association has found that a shortened schedule, dropped quality control procedures, pending lawsuits and the outside politicization of some parts of the 2020 census have raised questions about the quality of the nation’s head count that need to be answered if the final numbers are going to be trusted.The Census Bureau says it has counted 99.9% of households nationwide, though some regions of the country such as parts of Mississippi and hurricane-battered Louisiana fall well below that.As the Census Bureau winds down field operations over the next several days, there will be a push to get communities in those two states counted, said Kristen Clarke, president and executive director of the Lawyers’ Committee for Civil Rights Under Law, one of the litigants in the lawsuit.“That said, the Supreme Court’s order will result in irreversible damage to the 2020 Census,” Clarke said.___Follow Mike Schneider on Twitter at https://twitter.com/MikeSchneiderAP 6792

  

The US Postal Service is asking for the biggest price jump on stamps in its history.Facing pressure from the Trump administration to address a revenue shortfall, the Postal Service on Wednesday proposed raising the price of 1-oz. letters from 50 cents to 55 cents, which would be a record nominal increase if approved. The price of each additional ounce would go down slightly.The request was made by the USPS' board of governors, which has been operating on an emergency basis?because of a lack of confirmed members. It will have to be approved by the Postal Regulatory Commission."The Governors believe these new rates will keep the Postal Service competitive while providing the agency with needed revenue," the USPS said in a press release. "The Postal Service has some of the lowest letter mail postage rates in the industrialized world and also continues to offer a great value in shipping."Rates for mailing services -- which includes catalogs and magazines as well as letters -- are pegged to consumer prices. Those have been rising faster this year, but still limited the price hike for that category to 2.5 percent.Prices for packages, however, can float with market rates. The USPS wants to boost Priority Mail prices by an average of 5.9%. A small flat-rate box that costs .20 to ship, for example, would next year cost .90.The steep price increases come at a time when the USPS' losses have been mounting, dragged down in part by a requirement that the quasi-public agency pre-fund the cost of retiree health benefits.As letters and advertising mailers have been replaced by e-mail and online ads, the USPS has been making less and less money. Revenue from first-class mail declined from .4 billion in fiscal year 2015 to .6 billion in 2017.Package revenues fueled by the rise in e-commerce have been a bright spot, bringing in .5 billion in 2017, up from billion in 2015. But it hasn't made much of a dent in the .7 billion net deficit that the Post Office has accumulated over the years.The White House has proposed privatizing the Post Office, a plan that postal unions protested in nationwide demonstrations on Monday.President Donald Trump has repeatedly criticized the terms of USPS' contract to deliver Amazon packages, the details of which are confidential. The Postal Service says it makes a profit through the arrangement."Why is the United States Post Office, which is losing many billions of dollars a year, while charging Amazon and others so little to deliver their packages, making Amazon richer and the Post Office dumber and poorer?" Trump tweeted last December. "Should be charging MUCH MORE!"In April, Trump ordered a review of the Postal Service's business model by a task force led by the Treasury Department. Postal Service spokesman Carl Walton says the review has been completed, but that the agency hasn't seen it yet."I think they're waiting until after the elections," Walton said. "We're waiting just like everybody else." 3041

  

The University of Florida issued a statement of apology on Sunday, one day after several black students were removed from the stage by a white faculty member during the university's commencement. Video of the incident showed the graduates celebrating their walk down the graduation aisle by dancing, when the usher grabbed the students. University of Florida President W. Kent Fuchs released a statement, saying the staffer was "inappropriately aggressive."  496
