Brenda Francis settled into the Kingdom Hall in Calhoun, Georgia, in mid-March, surrounded by dozens of familiar faces. Signs cautioning against shaking hands and hugging were posted around the room. It felt weird to her but was certainly understandable with the threat of an outbreak looming. She herself already had stocked up on some masks and gloves.When it came time for members to comment on the Bible readings, Francis noticed the microphones typically passed around the room were now attached to the end of long poles.That was the moment Francis, a 69-year-old widow living in a small, semirural community in the South, realized just how dramatically the coronavirus pandemic was about to reshape her spiritual life, more than anything ever had in the 47 years since she was baptized as a Jehovah's Witness.A few days after the boom mics came out in the Kingdom Hall, word came down from the group's headquarters that, in the interest of safety, Jehovah's Witnesses should stop witnessing, its practice of in-person attempts at converting people to the group."People would be so receptive right now," she said of her ministry, "and we can't knock on doors."Across the country, most religious groups have stopped coming together in large numbers to pray and hold services, in keeping with stay-at-home orders. They have improvised with online preaching and even drive-in services as the faithful sit in cars. Mormons have stopped going door to door in the United States and called home many missionaries working abroad.Jehovah's Witnesses -- with 1.3 million U.S. members who hand out brochures on sidewalks and subway platforms and ring doorbells -- are one of the most visible religious groups in the nation. Members are called on to share Scriptures in person with nonmembers, warning of an imminent Armageddon and hoping to baptize them with the prospect of living forever.The decision to stop their ministries was the first of its kind in the nearly 150 years of the group's existence. It followed anguished discussions at Watchtower headquarters, with leaders deciding March 20 that knocking on doors would leave the impression that members were disregarding the safety of those they hoped to convert."This was not an easy decision for anybody," said Robert Hendriks, the group's U.S. spokesman. "As you know, our ministry is our life."It was for Francis, who became a Jehovah's Witness when she was in her 20s with a newborn and a member knocked on her door in Tennessee and persuaded her to attend a Kingdom Hall meeting. She converted. Her family was angry that she no longer came to holiday gatherings; the group doesn't believe in celebrating holidays or birthdays. Jehovah's Witnesses became her new family.The more she studied the Bible, the more she came to believe it led to eternal life. She needed to spread the word.Showing up cold on someone's doorstep didn't come naturally. She was so shy that once, she recalled, her high school principal -- "this huge Goliath guy" -- stood on her foot in a crowded hallway; she didn't say a word but waited in pain for him to move. She had considered a career going door to door as a Mason Shoes saleswoman, but after receiving a catalog, she never mustered the courage to even try to make a sale.To her, witnessing was different. Her faith had helped her stop smoking. It gave her meaning. She had seen people clean up their lives after attending meetings at Kingdom Hall."By the time I did go to doors, I was so convinced this was the right thing to do that I had no nervousness," Francis said.Through the years, she learned to build her pitch around a theme -- a Bible verse or a current event -- and tried not to sound rehearsed."You don't want to sound like a robot," she said. "You work from the heart. You want enthusiasm."Early this year, Francis had been seeing reports on Facebook about the virus sweeping through Wuhan, China. The host of a show she watched on YouTube, Peak Prosperity, had been warning that the outbreak could spread internationally.She bought masks and face shields, just in case. She started using plastic grocery bags to cover the gas pump handle when she filled up her tank.By early March, the virus still hadn't hit Gordon County, where Francis lives. But the possibility was weighing on her mind. The message on her favorite YouTube show was getting more dire as the host, Chris Martenson, a financial guru-turned-pandemic early warner, ratcheted up his pleadings for viewers to prepare themselves.Francis' 27-year-old granddaughter has a compromised immune system. As a senior citizen, she herself was vulnerable. She did what she always has done and channeled her own feelings into her door-knocking ministry. Do you think, she would ask people as she carpooled with other members to canvass the county, that the virus is a sign of the end of the world?"No one was paying much attention," she said.Elsewhere, in places like New York where infections were starting to climb, Jehovah's Witnesses members were feeling the pinch on their ministries.One of them, Joe Babsky, had been easing into conversations with members of his Planet Fitness gym in the Bronx for weeks. He knew them by first name only: Jerry, who had lost more than 100 pounds; Jason, who seemed to spend an hour on each body part; Bernie, a 78-year-old who was more fit than men half his age. Babsky had shown a few of them Bible verses and had made progress recently with Bernie discussing the logic behind the existence of an intelligent creator.Then the gym closed."All those conversations and others were cut short," Babsky said.Life continued as normal in Francis' town of Calhoun. She was convinced things were about to change, but she was too embarrassed to wear a mask -- until an encounter in Costco when a passing shopper coughed without covering her mouth.In mid-March, her Kingdom Hall meetings went virtual. Members logged into Zoom to share Bible Scriptures. Francis settled on one that she thought would resonate as she knocked on doors in her neighborhood across the county, which had by then registered a handful of COVID-19 cases.At the doorstep, Francis would start her pitch by asking people if they could make one thing in the world go away, what would it be? If the answer had to do with the pandemic, she would recite a couple of verses from the book of Luke:"There will be great earthquakes, and in one place after another food shortages and pestilences; and there will be fearful sights and from heaven great signs."All the signs were clear, she would announce. Armageddon was near. Her message finally seemed to be resonating with people.And then she got word to stop knocking on doors."This has been so much a part of our lives, so it was like, wow," she said. "I have often envisioned in paradise where going door to door would not be a thing because everyone knows God."This was not paradise.But Francis was convinced that the end of the world was not far away. There were just too many signs, she said. And so she and many other Jehovah's Witnesses members were more compelled than ever to witness any way they could. Many began writing letters or making phone calls to anyone whose numbers they had managed to collect before the pandemic hit.Masked and gloved, Francis hands out pamphlets and cards with her phone number on them to fellow shoppers at the grocery store.Last week, she sent a text to a woman in Hawkinsville, Georgia, a few miles away, whom she had been contacting from time to time. The woman said her restaurant had to close because of the pandemic and her brother-in-law was sick with the virus. A couple of days later he died.Francis texted Scriptures to the woman and told her that soon all the sickness on Earth would be over; all sins would be forgiven; paradise was near.The next day she received a written response: "Thank you so much for the information. It was such a comfort."This article originally appeared in The New York Times.(C) 2020 The New York Times Company

On Monday, officials in Los Angeles County released preliminary results of a study that suggest roughly 4.1% of the county's adult population has already had the coronavirus, which translates to between 221,000 and 442,000 people, factoring in adjustments for statistical margin of error.That's a much higher number than confirmed case counts indicate. (As of early Tuesday, the county had 13,816 cases.)"We haven't known the true extent of COVID-19 infections in our community because we have only tested people with symptoms and the availability of tests has been limited," Neeraj Sood, a professor of public policy at the University of Southern California and lead investigator on the study, said in a statement.Dr. Barbara Ferrer, LA County's public health director, said in a statement that the early results pointed to the possibility that many people may have been unknowingly infected.The study relies on rapid antibody tests, which have faced concerns about accuracy.And as The Mercury News reported, a Stanford study that also showed higher rates of infection in Santa Clara County drew criticism, although that was largely from statisticians over the study's methodology.Still, experts have emphasized that more studies will help develop a clearer picture of the virus's true prevalence.In any case, officials say it's crucial to continue to adhere to public health orders for many reasons, including that if more people are infected but asymptomatic, they could unknowingly spread the virus.______A change to the USNS Mercy's assignmentOn Monday, my New York Times colleague John Ismay and I spoke with leaders aboard the Navy hospital ship Mercy. Here's our dispatch about how their assignment has changed:In the weeks since the Mercy arrived at the Port of Los Angeles from San Diego, the hospital ship's mission has been clear: Serve as a crucial relief valve for patients who have not been infected with the coronavirus as hospitals fill up with patients sick with COVID-19.In recent days, the work has shifted, but that underlying goal has remained the same, the commanding officer of the ship's medical facility told us."FEMA, after having made an assessment of the situation and the local needs, has changed our assignment," said Capt. John Rotruck, the medical treatment team's commanding officer.The Mercy has sent 40 medical staff members -- two family practice doctors, 16 nurses and 20 corpsmen, including two respiratory technicians -- to help care for patients who do not have COVID-19 at a state-run skilled nursing facility in Orange County."We're essentially augmenting their staff," Rotruck said, as the anticipated surge in COVID-19 hospitalizations has, for now, been held at bay.The capacity onboard will decrease to 250 beds from 1,000, in large part as a result of that staffing shift -- although officials emphasized that leaves more than enough space at the rate the Mercy has been taking in patients.At the same time, leaders aboard the Mercy said that most of the military crew is moving off the ship to stay at nearby hotels to make it possible for crew members to keep their distance from one another as they work, eat and sleep.Sailors will be bused from their hotels to work their shifts aboard the ship.The move, which will decrease the number of crew members staying aboard the ship to roughly 140 from more than 800, came as the number of crew members who may have been exposed inched upward.By Monday, Rotruck said that nine crew members had tested positive for the coronavirus and that about 130 people were in quarantine because they had come into what federal officials define as close contact with at least one of those nine. All of those in quarantine tested negative.All nine who have COVID-19 were outpatients as of Monday -- meaning their cases were not severe enough to warrant being hospitalized -- and their conditions are being closely monitored.Rotruck said that moving crew members off the Mercy was unusual but not unprecedented.During a previous mission, for instance, some medical staff members flew to Vietnam to provide medical care to patients on the Mercy, although they did not sleep on the ship.However, Rotruck added, "We have not done it to this scale," with the vast majority of the ship's crew members living ashore.A spokesman said Friday that the crew aboard the Navy hospital ship Comfort, which is docked in New York City, recently moved most of its crew to hotels ashore as well.Rotruck said that the Mercy was ready to care for coronavirus-negative seniors living in nursing homes, as the governor has previously announced, but none had been transferred yet.Such nursing home patients may be moved to the Mercy for care through the typical intake process, if, for example, a facility needed to free up space to care for COVID-19 patients.As of Monday evening, the ship had taken in 65 patients total since it docked in San Pedro, and its crew had performed 22 surgeries. There were 13 patients still being treated onboard, meaning that 52 had been discharged.This article originally appeared in The New York Times.(C) 2020 The New York Times Company

Bill Gates has been big on vaccines since before the start of the coronavirus pandemic, but in a new blog posting, the Microsoft co-founder and billionaire philanthropist says the only way to end the pandemic for good is to offer a vaccine to almost all of the planet's 7 billion inhabitants. That's big. "We've never delivered something to every corner of the world before," Gates notes. It's especially big considering that a vaccine hasn't yet been approved for widespread use, and that it may take as long as a year to 18 months to win approval and start distribution.

Mediterranean sediments are shown to have up to 1.9 million tiny plastic pieces per square metre.

A satellite mission that bounces laser light off the ice sheets of Antarctica and Greenland has found that hundreds of billions of tons' worth of ice are being lost every year due to Earth's changing climate. Scientists involved in NASA's ICESat-2 project report in the journal Science that the net loss of ice from those regions has been responsible for 0.55 inches of sea level rise since 2003. That's slightly less than a third of the total amount of sea level rise observed in the world's oceans over that time. To track how the ice sheets are changing, the ICESat-2… Read More

For Jeff Anderson, 61, working from home during the coronavirus pandemic has been a respite from office politics and the chatter around the copy machine.But as the push to reopen the country's economy intensifies, so do feelings of dread at the idea of returning to the office, said Anderson, a self-described introvert and anthropology professor at Hobart and William Smith Colleges in Geneva, New York."Just walking from the parking lot to my office I feel like I could be sick," he said. "It's that bad."In wanting to work alone, Anderson is not alone. People other than introverts view a return to the office with sadness and anxiety, and not just because they still risk getting infected. A Gallup poll found a majority of U.S. adults working from home would prefer to continue doing so "as much as possible" after the pandemic.These fans of online work worry that they -- and the country itself -- will lose important benefits discovered during this unprecedented experiment in mass remote work. People who have never liked schmoozing with colleagues have found new heights of productivity away from meetings and office chitchat. People worried about climate change are eager to reduce their carbon footprints by avoiding commutes by car. And while many parents are desperate for schools and day care centers to reopen, some working parents are appreciating more time with their children.Before the pandemic, Christine Reilley had to wake up at 4:30 a.m. to catch an early bus to Manhattan where she works as senior director of strategy and innovation for the American Society of Mechanical Engineers."I'm better rested. I can devote more time to my work," she said. "Just saving the time and money of commuting, I really like this personally."Impossible for Some and 'Overrated' for OthersIt did not take long for naysayers to declare that working from home was "overrated."And yes, it is an option mostly for white-collar office workers. Telecommuting is rarely possible for people in manufacturing or service jobs, and for the health workers, emergency responders, grocery store clerks and delivery people who have been deemed essential personnel. And the more than 30 million Americans who have lost their jobs since March may be impatient about complaints from people still drawing paychecks.Nor can the other downsides be denied. Trying to meet on Zoom from a kitchen table with bored children and annoyed spouses complaining in the background is hardly good for productivity. Women say that video calls make it harder for them to get in a word during meetings dominated by men. This crisis has also increased the burdens on working mothers.Telecommuting was already a growing trend that left out many low-wage workers and was viewed warily by employers who worried that people were slacking off at home. Researchers warned that problem solving and creativity suffer when workers are isolated from one another. Isolated work can lead to loneliness and boredom. Remote workers have also reported they have had to work even longer hours.OK, So What Are the Benefits?For remote work to be successful, employers need to provide the right equipment and other support, said Laurel Farrer, chief executive of Distribute Consulting, a business consulting firm. And the employees must be able to get work done without supervision. If set up properly, experts and advocates say, remote work has many benefits:-- Less time on the road. Commuting by car has been linked to increased stress, more pollution and respiratory problems. The average American who drives to work spends 54 hours per year stuck in traffic, according to an analysis by the Texas A&M Transportation Institute.-- Greater productivity. One well-known study from 2014 led by Stanford professor Nicholas Bloom examined remote workers at a Chinese travel agency and found that they were 13% more efficient than their office-based peers.-- A cleaner environment (maybe). According to estimates from Global Workplace Analytics, a research and consulting firm, if everyone in the United States worked remotely half the time, it could reduce greenhouse gas emissions from vehicle travel by more than 51 million metric tons a year. Graphics showing the reduction in air pollution and pictures of clearer skies over cities like Los Angeles have been among the silver linings of the pandemic. Of course, when people return to work, the roads may fill up again, especially if people fear getting the virus on public transit. And even if more people start working remotely, they might use their cars more for errands closer to home, said Bill Eisele, a senior research engineer at the Texas A&M Transportation Institute. Office commuters make up only about 18% of all traffic, he said.-- Money saved. Global Workplace Analytics estimated that people could save, on average, $2,000 to $6,500 every year by not spending on things like gasoline and day care. Companies could spend less on real estate. The U.S. Patent and Trademark Office estimated it saved more than $38 million in 2015 by not using as much office space, according to a Harvard Business School working paper from November.-- More job satisfaction. A 2005 study found that job satisfaction increased with each additional hour people spent working remotely. But it stopped increasing beyond 15 hours worked remotely.-- Less sickness. Even as companies consider reconfiguring workplaces with plexiglass barriers on desks and special air filters, letting employees work from home can help keep them safe from communicable diseases (and not just COVID-19).-- More time for fitness. You may be able to squeeze in more workouts. "Having a little more time, if you're using it wisely, can be very beneficial," said Marilyn Skarbek, an assistant professor of exercise science at North Central College in Naperville, Illinois. "There are a lot of other things you can do around the house to keep you moving: laundry, cleaning -- all of that keeps you active. My house is definitely cleaner than normal." But there is a risk you could be more sedentary, she warned.Kate Lister, president of Global Workplace Analytics, predicted that workers will be looking for the "happy medium," splitting time between remote work and showing up at the office. The hope is that the pandemic will have shown managers that workers can be trusted to do their jobs without constant supervision."Any kind of flexibility is something that people are really, really ripe for, just some control over where and when they work," she said.Happy Tales From the Home OfficeMany people who had never considered this kind of working life have now had a taste of it, and they love it.Jacquie Benetua-Rolens, communications and engagement coordinator at Santa Cruz Community Health Centers in Santa Cruz, California, has a 2-year-old son who has become a daily part of Zoom meetings with colleagues, waving at them in his pajamas."There is this softened, unfiltered, more honest version of ourselves that I'm enjoying getting to know," Benetua-Rolens said. "There is room to be forgiving and understanding with each other and ourselves. And it's because we've all had to juggle."Benetua-Rolens said she often thinks of her small cubicle back at the office, which she decorated with plants and pictures of her two children."I used to love it," she said. "But I don't miss it at all. I don't want to go back to that even though my house is filthy."Jessica Keup, a 37-year-old single mother and a computer programmer in Ann Arbor, Michigan, moved to her parents' home in rural Tennessee with her 3-year-old son in mid-March, after her company told employees to work from home.Since then, she has been coding from the deck while her son plays with the goats, chickens and peacocks that roost on the vast property.Keup said the solitude has made her more focused and more productive. Her work is not interrupted by chatty colleagues who want to say hi or need help fixing a computer glitch."The people who are in the office who are extroverts stand out and talk a lot and can take the oxygen out of the room," she said.At least one poll from early in the pandemic suggests a strong preference for remote work. Gallup found that almost 60% of Americans working from home would prefer to work remotely "as much as possible" after restrictions are lifted, with 40% saying they preferred to return to the workplace. The online survey of 2,276 randomly selected adults was conducted from March 14 through April 2. It had a margin of sampling error of plus or minus 4 percentage points.At the very least, some workers would like to see employers put lessons of the pandemic into practice, including more compassionate management in general.Rico Sisney, who works for Greenpeace USA, said he would like to continue seeing the kinds of emails his organization has been sending lately encouraging employees to take walks and small breaks."Organizations can continue that even when there is not a pandemic," Sisney said. "Highlight mental health."Christine de Denus, a chemistry professor at Hobart and William Smith Colleges, said she has relished the quiet of working from her porch. She thinks workplaces should adapt to all styles of working."Go to the people and say, 'How can I help you thrive?'" de Denus said. "Just because I'm quiet in a meeting doesn't mean I don't have ideas."When the time comes to return to the office, Keup said she plans to ask if she can work two to four weeks a year from Tennessee."It's beautiful. It's resting and restorative," she said. "And I'll miss that."This article originally appeared in The New York Times.(C) 2020 The New York Times Company

The third time's the charm for the Allen Institute for Brain Science's 3-D atlas of the mouse brain. Version 3 of the atlas, known as the Allen Mouse Brain Common Coordinate Framework or CCFv3, is the subject of a research paper published today in the journal Cell. It builds on a partial brain map that focused on the mouse cortex and was released in 2016. Previous versions of the atlas were rendered with lower-resolution 3-D maps. The latest high-resolution maps are fine enough to pinpoint the locations of individual brain cells — which is crucial for interpreting datasets that contain thousands… Read More

The following is a brief roundup of the latest scientific studies on the novel coronavirus and efforts to find treatments and vaccines for COVID-19, the illness caused by the virus. A new antibody test is highly accurate at determining whether people have been infected with the novel coronavirus, according to a study published on Friday in The Journal of Clinical Microbiology. Researchers at the University of Washington School of Medicine found the test, manufactured by Abbott Laboratories, had a specificity rate of 99.9% and a sensitivity rate of 100%, suggesting little chance of incorrectly diagnosing a healthy person as having been infected and virtually no chance of a false negative readout.

As Elon Musk's Starlink and Jeff Bezos's Project Kuiper race to create high-speed internet using satellites orbiting Earth, there's a small problem that could get in the way: debris. From dead spacecraft that have been around since the dawn of the space age to flecks of paint smashing windows on the International Space Station, rubbish is clogging up our orbits. And with objects moving as fast as 15,500mph (25,000 kmph), the satellite services we've come to depend on are at constant risk of collision. So how to fix the problem with junk in space?
