From building up defenses in the nose to slowing down a virus’s ability to make copies of itself, scientists are rolling out a raft of creative approaches to fighting infection
Some wavelengths of light in a range called far-UVC kill microbes in experiments and appear to be harmless to people. Could they be used to make indoor spaces safer against the coronavirus?
Covid long-haulers experience a litany of symptoms, and researchers have proposed a variety of theories to explain them. It’s a morass to figure out, but the answers are important for the multitudes still suffering from an infection that happened to them months or even years ago.
Psychologists are beginning to understand that for some people, intense and sustained feelings of loss are symptoms of a serious condition — one that can last for years and erode wellbeing

OPINION: A neuroscientist says that he’s particularly worried about kids, who may have spent much of last year learning online. Some easy hacks can help.
Hesitancy rates are falling but they’re still sizable, especially among certain groups. Easy access and trusted community messengers are keys to moving the needle.

Antibiotics abound, but virus-fighting drugs are harder to come by, and Covid-19 amply shows how much we need them. Fortunately, scientists are getting better at making and finding them.
They play an outsize role in the economy, and in strengthening communities. Their prospects for surviving the pandemic may seem dim, but there are some encouraging signs, experts say — and emerging winners and losers.
What will become of children growing up during the pandemic? There’s reason for concern, but the research on resilience is reassuring. A developmental psychologist explains what adults can do to protect youngsters from long-term harm.
Wearable devices already collect vital signs like heart rate and skin temperature. New algorithms can use them to catch illness early — leading to urgent efforts to help battle the pandemic.
OPINION: Requiring companies to give unwell workers compensated time off isn’t a burden. It’s smart public health policy that reduces the spread of disease.
Conspiracy theories seem to meet psychological needs and can be almost impossible to eradicate. One remedy: Keep them from taking root in the first place.
Traffic planners, securities traders and military strategists all use it. Simulating the behavior of millions of idiosyncratic individuals also may be the best way to understand complex phenomena like pandemics.
Humans can transmit many diseases to chimps, orangutans and their kin. People who study and care for the creatures are taking lockdown-style measures to limit the risk.
Our national and social identity is deeply rooted in values like freedom, equality and order. A political scientist explores how these ideas affected the US response to the pandemic.
TIMELINE: From colonial efforts to control smallpox outbreaks to antimalarial campaigns targeting mosquitoes, the American effort grew for centuries. But cutbacks have weakened it in the past decades.
Covid-19 has exposed the weak spots of the US public health system — and that presents an opportunity, says an epidemiologist, for the nation to recognize the problems and act to fix them
OPINION: Many Americans say they won’t take a vaccine. I am not one of <br xmlns="http://pub2web.metastore.ingenta.com/ns/"/>them — and I have the shots to prove it.
OPINION: Because of the pandemic, I couldn’t visit him in his nursing home, and because of his dementia he couldn’t understand why. Mismanagement of this crisis has failed the elderly and caused incalculable hurt.

Pathogens can make us sick. Just how sick depends on genetic variations, including ones that sabotage immune molecules called interferons. A better understanding could lead to new treatments for Covid-19 and other scourges.
OPINION: People beat artificial intelligence hands-down at puzzling out new ways to fold molecules for a potential SARS-Cov-2 immunization. Thousands more players are needed.
Funerals, burials and other ways of communally commemorating those who have died have always been part of human history. The need for social distancing has upended these psychologically important rituals and fostered creative alternatives.
Some linger in the body for a lifetime. The one causing Covid-19 probably isn’t one of them, but it and others can create mischief long after the immune system appears to have banished them.
Out-of-control clotting can endanger some patients even after the virus has gone. Clinicians and researchers are trying to understand why it happens and how best to manage the problem.

From mask wearing to physical distancing, individuals wield a lot of power in how the coronavirus outbreak plays out. Behavioral experts reveal what might be prompting people to act — or not.
It began with an email from Wuhan, a Maine laboratory and mouse sperm from Iowa. Now that lab is on the verge of supplying a much-needed animal for SARS-CoV-2 research.
Reports of patients with neurological symptoms have emerged during the pandemic. Scientists don’t yet know whether these are a direct effect of the virus or part of the body’s response to infection.
Studies on astronauts and Antarctic crews reveal how extreme confinement affects small groups. Scientists are racing to figure out isolation’s impact on the rest of us.
Antibodies should indicate if someone has had an infection in the past. But the promise of “immunity testing” is plagued by uncertainty about how the immune system responds to the coronavirus, as well as concerns about the tests’ accuracy.
We know pathogens from other species can endanger us. Scientists are better equipped than ever to do something about it, but political buy-in is crucial.
