From Tashkent to Samarkand and Bukhara, travel writer Caroline Eden believes Uzbekistan offers a dazzling mix of traditional style and a modern outlook

Twenty five years after the fall of the USSR, it’s interesting how the Soviet-era hangover lingers in Uzbekistan. Hulking apartment blocks are gradually being upgraded, and while you won’t spot statues of Lenin (they’ve been replaced by the nomadic conqueror Tamerlane and celebrated medic Ibn-Sina) you will see plenty of samovars (Russian kettles) and Soviet military medals for sale in the markets. But you will also see master ikat weavers reviving weaving traditions, and many musicians and artists are now turning to their Islamic heritage for influence. This mix of Soviet legacy and Uzbek Islam is one of the things that makes the country so fascinating.

Unesco has named the capital of Rajasthan, India, a world heritage site, partly for its jewellery and artisanal traditions, which continue to thrive on one of its main commercial streets

‘Sir, want precious stones?” a man asks me, quietly. I am on the Johari Bazaar, one of Jaipur’s most notable thoroughfares, a straight colonnade screened above by the facades of adjoining houses. Everything is painted orange, terracotta and burnt pink. The man wears white shalwar kameez, and an air of indifference. He unfolds white paper, revealing colourful stones. “Emeralds, sapphires, rubies …” he says. He is among one of several groups of men gathered in this area; they’re local dealers, discussing prices. The avenue, whose name means gem shop road, is lined with dozens of shops displaying magnificent necklaces, bracelets and rings.

Amid the historic quarter’s busy streets, a thousand workshops maintain centuries-old craftmaking traditions. These workers’ ancient skills are celebrated in a new exhibition at London’s Royal Geographical Society

“Whatever manufactured items there are in the world,” wrote the Ottoman traveller Evliya Çelebi in 1671, “the poor of Cairo get hold of them, set them out and trade in them.” Nearly 350 years later, this tradition lives on in al-Darb al-Ahmar. This neighbourhood of 100,000 people, south-east of central Cairo, is said to be home to a thousand workshops. The place teems with artisans crafting everything from tents, books, boxes and brass lanterns to glass bowls and silk carpets.

This centuries-old teahouse in Sichuan province and its regulars are a world away from China’s modern megacities

Out in the western suburbs of Sichuan’s capital, Chengdu, the town of Pengzhen is home to what’s said to be the oldest teahouse in China. About 300 years old, the Guanyin Pavilion is at the heart of a tiny community of historic streets where, against a tide of rapid modernisation, the local population proudly preserves its heritage and traditional way of life.

A new virtual exhibition, What the Traveller Saw, the first of its kind by the Royal Geographical Society, marks the centenary of the birth of the writer and former Observer travel editor

Map-makers insert fake towns or trap-streets to catch out plagiarists, but Agloe, in New York state, took on a strange life of its own

In 2008, Argleton village in west Lancashire appeared on Google, complete with weather reports, a job site and an estate agent advertising houses for sale. Argleton vanished two years later. While its site was – and still is – a damp field in the middle of nowhere, it’s worth noting that Argleton is an anagram of G Not Real. Although Google never admitted to having created it, Argleton was a phantom settlement, planted as a trap.

In the world of digital mapping and cartography, snares to catch unwary plagiarists take the form of fake roads or places, known as “trap streets” or “paper towns”. For some, such as Lye Close or Noereal Road, the clue is in the name. (A real alleyway in Cardiff that served as a trap street in the 2014 Dr Who episode Face the Raven may, conversely, be the world’s only fictional fictional street.)

Elena Ferrante’s Naples, Umberto Eco’s medieval mysteries, EM Forster’s Tuscany … Italy comes alive through these great books
• 10 of the best novels about France

Long before Covid-19, there were always bad things in the press about Italy: corruption, mafia, bureaucracy. But, whenever I went, life seemed to work out even so. People may be poor but they still sit in the sun, drink and chat; music and culture are a birthright; the right seems in the ascendant but on the ground it feels blessed with far-seeing idealists – it has almost four times as much land under organic cultivation as the UK, for example. For now, my remedy to the withdrawal symptoms I feel is to visit via the written word. Many writers have set books in Italy – I was sorry to leave out Martin Amis’s The Pregnant Widow (Calabria), and Ali Smith’s How to be Both (Ferrara) – but here are my top 10 romanze italiane.

With no alternative but to explore the nature on their doorstep, three writers describe the joy of enforced slow travel

It is a place I’d discovered before the virus: a left-hand bend in a narrow stream, a couple of steps off the footpath. There is nothing remarkable there, or not at first glance. There are breeze blocks in the stream bed and plastic bags deeply embedded in the roots of an alder tree. With a few variations, it could be anywhere in Britain: the neglected corner of a city park, the back of a private garden, behind a national park cafe. It’s just one of those spots that no one ever thinks to stop at and, if not for Covid-19, I would not have begun visiting daily, pausing for a few breaths before continuing. I saw the first snowdrops appear there, followed by primroses; then they were swamped by wild garlic and wood anemone. One morning a weasel shot out of a hole under a root and sprinted up the opposite bank. It was the first of several surprises.

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

The first known comet to visit us from another star system has an unusual make-up.

The National Oceanic and Atmospheric Administration says it has forged a new agreement with Vulcan Inc., the Seattle-based holding company created by the late Microsoft co-founder Paul Allen, to share data on ocean science and exploration. The memorandum of understanding builds on an existing relationship between NOAA and Vulcan. “The future of ocean science and exploration is partnerships,” retired Navy Rear Admiral Tim Gallaudet, assistant secretary of commerce for oceans and atmosphere and deputy NOAA administrator, said today in a news release. “NOAA is forging new collaborations, such as the one with Vulcan, to accelerate our mission to map, explore… Read More

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

The 5,100 sq km behemoth which broke away from Antarctica in 2017 drops its own large chunk of ice.

One month after the debut of the COVID-19 Open Research Dataset, or CORD-19, the database of coronavirus-related research papers has doubled in size – and has given rise to more than a dozen software tools to channel the hundreds of studies that are being published every day about the pandemic. In a roundup published on the ArXiv preprint server this week, researchers from Seattle's Allen Institute for Artificial Intelligence, Microsoft Research and other partners in the project say CORD-19's collection has risen from about 28,000 papers to more than 52,000. Every day, several hundred more papers are being published, in… Read More

NASA has awarded a $2 million grant to the Jet Propulsion Laboratory, The Aerospace Corp. — and Xplore, a Seattle-based space venture — to develop the design architecture for a far-out telescope array that would use the sun's gravitational field as a lens to focus on alien planets. The Phase III award from the NASA Innovative Advanced Concepts program, or NIAC, would cover two years of development work and could lead to the launch of a technology demonstration mission in the 2023-2024 time frame. Xplore's team will play a key role in designing the demonstration mission's spacecraft, which would be… Read More

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. Some… Read More

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 the first time, Virgin Galactic's SpaceShipTwo rocket plane flew free in the skies over New Mexico's Spaceport America, its new base of operations. The SpaceShipTwo plane, known as VSS Unity, has made rocket-powered flights beyond the 50-mile space milestone during tests at California's Mojave Air and Space Port, but today's unpowered test flight was the first to be flown from Spaceport America. "Today's VSS Unity flight is another exciting milestone for Virgin Galactic's progress in New Mexico," Dan Hicks, executive director of the New Mexico Spaceport Authority, said in a news release. "We are extremely happy and proud of… Read More

Everything is in readiness for the first mission to send humans into orbit from U.S. soil since NASA retired the space shuttle fleet in 2011 – from the SpaceX Crew Dragon capsule that will take two astronauts to the International Space Station, to the parachutes that will bring them back down gently to an Atlantic Ocean splashdown, to the masks that NASA's ground team will wear in Mission Control. The fact that the launch is coming in the midst of the coronavirus pandemic has added a weird and somewhat wistful twist to the history-making event. "That certainly is disappointing," NASA… Read More

NASA Administrator Jim Bridenstine has confirmed in a tweet that the space agency is working with movie star Tom Cruise on a project that involves shooting a film on the International Space Station. Deadline Hollywood reported on Monday that a space movie project involving NASA and SpaceX is in the works, but that "no studio is in the mix at this stage." Bridenstine followed up with a tweet saying that NASA was "excited" to be working with Cruise, and explaining that "we need popular media to inspire a new generation of engineers and scientists to make NASA's ambitious plans a… 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.

BBC News looks at what we know and don't know about the Earth's changing climate.

Two Seattle-area space ventures — Tethers Unlimited and Rocket Propulsion Systems — are among 124 businesses receiving $750,000 Phase II grants from NASA's Small Business Innovation Research program. The two-year grants, announced today, support the further development of technologies that can benefit future space missions as well as life on Earth. All of the recipients, hailing from 31 states in all, received $125,000 Phase I grants during earlier rounds of funding. "We are encouraged by the ingenuity and creativity we’ve seen from these companies in their Phase I work," Jenn Gustetic, NASA's SBIR program executive said in a news release.… Read More

NASA has awarded the University of Washington a $499,864 grant to develop a competition that calls on students to turn a simulated lava tube into a habitat suitable for harboring humans on the moon or Mars. The exploration and habitation skills competition will be funded as part of NASA's Artemis Student Challenges program, which plays off the themes of the Artemis moon program to inspire the next generation of explorers and engineers. The competition will involve navigating a rover through a facsimile lava tube and surface structures, generating maps, identifying valuable resources and deploying an airtight barrier to seal the… Read More

There are decisions being made right now that could have an effect on global populations for generations to come. As part of this project, we commissioned an artist to investigate some of the themes raised in the podcasts.

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?

Two gems from the wizard of recreational maths

UPDATE: Puzzle solutions can be read here.

Today’s column is a celebration of John Horton Conway, the legendary British mathematician, who died of coronavirus earlier this month, aged 82.

Conway was an inspirational, iconoclastic genius who invented and studied countless puzzles and games, in addition to his more highbrow work in group theory, number theory, geometry, topology and many other fields.

The answers to today’s puzzles

Earlier today I set you two puzzles that the late John Horton Conway suggested for this column:

1) The Miracle Builders

Smartphones can be used to digitally trace Covid-19. But not if the public don’t download an app over privacy fears – or find it won’t work on their device

The idea of the NHS tracing app is to enable smartphones to track users and tell them whether they interacted with someone who had Covid-19. Yet this will work only if large proportions of the population download the app. No matter how smart a solution may appear, mass consent is required. That will not be easy. Ministers and officials have failed to address the trade-offs between health and privacy by being ambiguous about the app’s safeguards.

Instead of offering cast-iron guarantees about the length of time for which data would be held; who can access it; and the level of anonymity afforded, we have had opacity and obfuscation. It is true that we are dealing with uncertainties. But without absolute clarity about privacy the public is unlikely to take up the app with the appropriate gusto.

The chance to put biodiversity and the environment at the heart of recovery from the pandemic should not be squandered

One night in April, birdwatchers from around Britain stepped outside their doors and listened intently to something most of them had never experienced before: the fluting, mysterious, melancholy cry of the common scoter on the wing.

Flocks of these dusky sea ducks were beating their way over Britain on their long migratory journey towards their Arctic breeding grounds, easily audible to the naked ear. The first great wave was heard on the Wirral before being picked up in the Peak District, and at last by the Humber. A second wave was made out as flocks made their way along the line of Hadrian’s wall, from the Solway Firth in the west to Northumberland in the east. A third wave flew above listeners from the Severn estuary to the Wash. The birds were heard in urban Blackburn, Stalybridge, Bristol and London. It was thanks to social media that so many listeners were alert to the birds’ progress – and thanks to the silence of lockdown that they could be heard.

Lawyers say failure to provide adequate PPE may amount to corporate manslaughter

The deaths of more than 50 hospital and care home workers have been reported to Britain’s health and safety regulator, which is considering launching criminal investigations, the Guardian has learned.

The Health and Safety Executive (HSE), which investigates the breaking of safety at work laws, has received 54 formal reports of deaths in health and care settings “where the source of infection is recorded as Covid-19”. These are via the official reporting process, called Riddor: Reporting of Injuries, Diseases and Dangerous Occurrences.

Letter seeks to dispel view that Prof Neil Ferguson was single architect of lockdown idea

• Coronavirus – latest updates

A group of leading UK scientists have insisted that the scientific basis for the coronavirus lockdown is the work of a large group of experts, and that epidemiologist Prof Neil Ferguson is just one voice among many.

In a letter co-ordinated by Dr Thibaut Jombart, an associate professor at the London School of Hygiene and Tropical Medicine, more than 25 prominent scientists said debates after Ferguson’s “individual error” – in which he flouted lockdown rules by receiving visits at home from his lover – had amplified a misconception that he alone persuaded the government to change policy.

Sage told widespread use of antibody tests could lead to criminal behaviour, papers reveal

• Coronavirus – latest updates

Downing Street’s scientific advisers feared people might intentionally seek to contract coronavirus and that a black market in fake test results could emerge if employers allowed workers to return only when they had a positive antibody test.

The Scientific Advisory Group for Emergencies, known as Sage, was warned last month by its behavioural psychology subgroup that the widespread introduction of antibody tests could lead to a range of potentially dangerous and even criminal “negative behavioural responses” if not handled well.

Recent deaths have stood out, but scientists say they must be interpreted with caution

Amid the steady stream of stories on the lives lost to coronavirus are cases that stand out as remarkable. In the past month, at least two pairs of twins have died in Britain and two pairs of brothers, all within hours or days of each other. But do the deaths point to genetic factors that make some more likely than others to succumb to the disease?

Most scientists believe that genes play a role in how people respond to infections. A person’s genetic makeup may influence the receptors that the coronavirus uses to invade human cells. How resilient the person is to the infection, their general health, and how the immune system reacts will also have some genetic component.
