| If any place was prepared for quarantine, it was Milton Keynes. Two years before the pandemic, a start-up called Starship Technologies deployed a fleet of rolling delivery robots in the small city about 50 miles northwest of London. | If any place was prepared for quarantine, it was Milton Keynes.

| The squat six-wheeled robots shuttled groceries and dinner orders to homes and offices. As the coronavirus spread, Starship shifted the fleet even further into grocery deliveries. Locals like Emma Maslin could buy from the corner store with no human contact. | The squat six-wheeled robots shuttled groceries and dinner orders to homes and offices.

| The sudden usefulness of the robots to people staying in their homes is a tantalizing hint of what the machines could one day accomplish — at least under ideal conditions. Milton Keynes, with a population of 270,000 and a vast network of bicycle paths, is perfectly suited to rolling robots. Demand has been so high in recent weeks, some residents have spent days trying to schedule a delivery. | The sudden usefulness of the robots to people staying in their homes is a tantalizing hint of what the machines could one day accomplish — at least under ideal conditions.

| Industry veterans know this well. Gabe Sibley, an engineer and a professor who previously worked with the National Aeronautics and Space Administration, started Zippy for sidewalk deliveries in 2017. But the San Francisco company quickly ran into challenges. The robots could move only at the pace of walking, around 1 mile per hour. That severely limits the delivery area, particularly for hot food, Mr. Sibley said. | Industry veterans know this well.

| Founded in 2014 and backed by more than $80 million, Starship Technologies is based in San Francisco, and it has deployed most of its robots on college campuses in the United States. Equipped with cameras, radar and other sensors, the robots navigate by matching their surroundings to digital maps built by the company in each new location. | Founded in 2014 and backed by more than $80 million, Starship Technologies is based in San Francisco, and it has deployed most of its robots on college campuses in the United States.

| The company chose Milton Keynes for a wider deployment in part because the robots could navigate it with relative ease. Built after World War II, the city was carefully planned, with most streets laid out in a grid and bicycle and pedestrian paths, called “redways,” running beside them. | The company chose Milton Keynes for a wider deployment in part because the robots could navigate it with relative ease.

| Smaller deliveries suit Ms. Page because she lives alone. A longtime vegan, she can order nut milk and margarine straight to her door. But like the grocery vans that deliver larger orders across the city, the Starship robots are ultimately limited by what is on the shelves. | Smaller deliveries suit Ms. Page because she lives alone.

| Residents like Ms. Page set deliveries through a smartphone app. They typically pay a British pound (about $1.20) for each delivery, but in Milton Keynes, Starship has raised the price to as much as £2 during the busiest times so more people will shop in off hours. | Residents like Ms. Page set deliveries through a smartphone app. They typically pay a British pound (about $1.20) for each delivery, but in Milton Keynes, Starship has raised the price to as much as £2 during the busiest times so more people will shop in off hours. |
| The robots deliver groceries to doctors, nurses and other employees of the N.H.S. for free. They even join the Thursday night tribute to the N.H.S., blinking their headlights as residents clap and cheer from their doorsteps. The fleet of 80 robots will soon expand to 100. | The robots deliver groceries to doctors, nurses and other employees of the N.H.S. for free.

| A study by European scientists is the first to document a strong statistical link between genetic variations and Covid-19, the illness caused by the coronavirus. Having Type A blood was linked to a 50 percent increase in the likelihood that a patient would need to get oxygen or to go on a ventilator, according to the new study. | |
| The unemployment rate fell to 13.3 percent in May, the Labor Department said on June 5, an unexpected improvement in the nation’s job market as hiring rebounded faster than economists expected. Economists had forecast the unemployment rate to increase to as much as 20 percent, after it hit 14.7 percent in April, which was the highest since the government began keeping official statistics after World War II. But the unemployment rate dipped instead, with employers adding 2.5 million jobs, after more than 20 million jobs were lost in April. | The unemployment rate fell to 13.3 percent in May, the Labor Department said on June 5, an unexpected improvement in the nation’s job market as hiring rebounded faster than economists expected.

| Mass protests against police brutality that have brought thousands of people onto the streets in cities across America are raising the specter of new coronavirus outbreaks, prompting political leaders, physicians and public health experts to warn that the crowds could cause a surge in cases. While many political leaders affirmed the right of protesters to express themselves, they urged the demonstrators to wear face masks and maintain social distancing, both to protect themselves and to prevent further community spread of the virus. Some infectious disease experts were reassured by the fact that the protests were held outdoors, saying the open air settings could mitigate the risk of transmission. | Mass protests against police brutality that have brought thousands of people onto the streets in cities across America are raising the specter of new coronavirus outbreaks, prompting political leaders, physicians and public health experts to warn that the crowds could cause a surge in cases.

| Exercise researchers and physicians have some blunt advice for those of us aiming to return to regular exercise now: Start slowly and then rev up your workouts, also slowly. American adults tended to be about 12 percent less active after the stay-at-home mandates began in March than they were in January. But there are steps you can take to ease your way back into regular exercise safely. First, “start at no more than 50 percent of the exercise you were doing before Covid,” says Dr. Monica Rho, the chief of musculoskeletal medicine at the Shirley Ryan AbilityLab in Chicago. Thread in some preparatory squats, too, she advises. “When you haven’t been exercising, you lose muscle mass.” Expect some muscle twinges after these preliminary, post-lockdown sessions, especially a day or two later. But sudden or increasing pain during exercise is a clarion call to stop and return home. | Exercise researchers and physicians have some blunt advice for those of us aiming to return to regular exercise now: Start slowly and then rev up your workouts, also slowly.

| States are reopening bit by bit. This means that more public spaces are available for use and more and more businesses are being allowed to open again. The federal government is largely leaving the decision up to states, and some state leaders are leaving the decision up to local authorities. Even if you aren’t being told to stay at home, it’s still a good idea to limit trips outside and your interaction with other people. | States are reopening bit by bit.

| Touching contaminated objects and then infecting ourselves with the germs is not typically how the virus spreads. But it can happen. A number of studies of flu, rhinovirus, coronavirus and other microbes have shown that respiratory illnesses, including the new coronavirus, can spread by touching contaminated surfaces, particularly in places like day care centers, offices and hospitals. But a long chain of events has to happen for the disease to spread that way. The best way to protect yourself from coronavirus — whether it’s surface transmission or close human contact — is still social distancing, washing your hands, not touching your face and wearing masks. | Touching contaminated objects and then infecting ourselves with the germs is not typically how the virus spreads.

| Common symptoms include fever, a dry cough, fatigue and difficulty breathing or shortness of breath. Some of these symptoms overlap with those of the flu, making detection difficult, but runny noses and stuffy sinuses are less common. The C.D.C. has also added chills, muscle pain, sore throat, headache and a new loss of the sense of taste or smell as symptoms to look out for. Most people fall ill five to seven days after exposure, but symptoms may appear in as few as two days or as many as 14 days. | Common symptoms include fever, a dry cough, fatigue and difficulty breathing or shortness of breath.

| If air travel is unavoidable, there are some steps you can take to protect yourself. Most important: Wash your hands often, and stop touching your face. If possible, choose a window seat. A study from Emory University found that during flu season, the safest place to sit on a plane is by a window, as people sitting in window seats had less contact with potentially sick people. Disinfect hard surfaces. When you get to your seat and your hands are clean, use disinfecting wipes to clean the hard surfaces at your seat like the head and arm rest, the seatbelt buckle, the remote, screen, seat back pocket and the tray table. If the seat is hard and nonporous or leather or pleather, you can wipe that down, too. (Using wipes on upholstered seats could lead to a wet seat and spreading of germs rather than killing them.) | If air travel is unavoidable, there are some steps you can take to protect yourself.

| Taking one’s temperature to look for signs of fever is not as easy as it sounds, as “normal” temperature numbers can vary, but generally, keep an eye out for a temperature of 100.5 degrees Fahrenheit or higher. If you don’t have a thermometer (they can be pricey these days), there are other ways to figure out if you have a fever, or are at risk of Covid-19 complications. | Taking one’s temperature to look for signs of fever is not as easy as it sounds, as “normal” temperature numbers can vary, but generally, keep an eye out for a temperature of 100.5 degrees Fahrenheit or higher.

| The C.D.C. has recommended that all Americans wear cloth masks if they go out in public. This is a shift in federal guidance reflecting new concerns that the coronavirus is being spread by infected people who have no symptoms. Until now, the C.D.C., like the W.H.O., has advised that ordinary people don’t need to wear masks unless they are sick and coughing. Part of the reason was to preserve medical-grade masks for health care workers who desperately need them at a time when they are in continuously short supply. Masks don’t replace hand washing and social distancing. | The C.D.C. has recommended that all Americans wear cloth masks if they go out in public.
