What does it mean to have prediabetes?

It’s complicated: Prediabetes has multiple definitions and there may be different subtypes. But for many people who develop it, changes in lifestyle drastically lower the risk of progressing to diabetes.

Why don’t kids tend to get as sick from Covid-19?

Some children have been hospitalized and some have died, but at a tiny fraction of the adult rate. As children head back to school, scientists are hoping that research will provide answers.

The challenges of antiviral treatments

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.

Getting a Covid-19 vaccine — quickly and safely

Researchers around the globe are working with unprecedented speed to find the vaccines we need to find our way through the pandemic. What’s the bar for safety and effectiveness?

How we make decisions during a pandemic

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.

The time of trials: Waiting for a coronavirus vaccine

An infected and impatient world needs protection from Covid-19, but rushing it won't be easy. How can we speed up a complicated process?

Covid-19 antibody testing: Tougher than true/false

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.

How disease sleuths are using genomics to track the coronavirus

Rapid sequencing of viral genomes can help public health officials figure out the origins, spread and nature of quickly moving epidemics

What is a cytokine storm?

An immune reaction gone wild seems to be linked with the most severe cases of pandemic Covid-19. Here’s what happens.

An old problem: How immune responses weaken with age

The body’s defenses lose flexibility and diversity over time, and protective responses to vaccines weaken as well. Scientists are working on ways to boost seniors’ protections against influenza, the novel coronavirus and other pathogens.

Fighting fire with fire ... and fauna

Climate change is aggravating the seasonal burns that Australia has always known. They won’t be snuffed out, but new ecological strategies may help.

The tricky task of tallying carbon

To slow or stop global warming, the world agrees it must cut carbon dioxide emissions. But monitoring each nation’s output of greenhouse gases is not always straightforward.

Twilight of the eye

Our bodies and abilities deteriorate with age, and sight is no exception. Physical changes to the visual system cloud it in multiple ways.
