The tiny, flying creatures carry all sorts of viruses but don't get sick. How do they do that? We meet the researchers who are mapping bat genomes and studying the animal's ability to fend off inflammation. What they find could help humans better combat the next pandemic. Special thanks to Bradley Klein for allowing us to use his bat call sounds. He's given bat walks in New York's Central Park and surrounding areas for more than a decade.

Research on a vaccine for the new coronavirus is progressing swiftly because of the legacy of scientists working on past diseases. Some of society's most devastating viruses ended up improving the way we study illness and search for cures. We explore the thread that connects research on polio and the new virus, SARS-CoV-2, and consider whether the pandemic will inform future generations of virologists.

Viruses are ubiquitous, found in every crevice on earth. Some, like SARS CoV 2, can end up killing their hosts. But researchers credit ancient viruses with helping us form long term memories. As parts of the world reopen for business, we consider how these little packets of genetic material are not just our enemy, but helped us to evolve. Viruses, it turns out, shaped our genome, and will like be part of our evolutionary future.

Artificial Intelligence can speed up research and improve accuracy. Those qualities are also key to suppressing the spread of Covid-19. With the globe clamoring for solutions to the pandemic, institutions, governments, universities and startups are turning to AI to shave precious time off the quest for a Covid-19 cure.

The market for hemp-based CBD products is exploding. And China wants in on the potential profits. But CBD is highly regulated in China, and THC is illegal. Will China make room for this lucrative product?

The nature of work is evolving. Technology is already an integral part of most jobs, but new developments are changing the way we navigate the workplace. From hiring managers using artificial intelligence and virtual reality, to apps that help workers find their way through maze-like mega offices, the office of tomorrow is already being tested. And lots of people are wondering if technological advancements will keep them working forever.

The clues to heredity hidden in our DNA have long been the purview of scientists. But in recent years, commercial DNA tests have made unlocking those secrets cheaper and easily accessible for millions of people. While most just find out about their ancestry, for some, the tests have opened Pandora's box. WSJ's Amy Dockser Marcus introduces us to three different stories of DNA tests with unexpected consequences.

For the past few decades, governments in earthquake-prone regions have built up early warning systems. Now, private tech companies are getting into the earthquake business. (Reporters Daniela Hernandez and Robbie Whelan)

The global videogame industry is worth an estimated $150 billion-and it's rapidly growing and evolving. As part of the WSJ Tech Live conference, columnist Jason Gay spoke with Andrew Wilson, chief executive of Electronic Arts, the maker of 'Apex Legends,' 'Need for Speed,' 'FIFA' and 'The Sims,' about how esports, mobile gaming on social networks and mixed-reality games are changing the way people play.

Artificial intelligence has been compared to electricity, meaning that it will soon be integral to the world as we know it. There's an arms race for global dominance in AI, especially between the U.S. and China. But what do experts in the field have to say? Where are they optimistic, where do they see challenges-and where are they raising red flags?

What will keep the engine of tech innovation running in an era of skeptical users and wary regulators? From driverless cars to outer-space colonies, two moonshot thinkers talk about their cutting-edge work and how calculated risks may spark the next giant leap for mankind.

Demand for donated organs far outstrips supply. But researchers are working to remedy the crisis using everything from gene-edited pigs to 3D-printed tissue.

Advances in gene editing and DNA analysis are allowing parents unprecedented control over the traits their children will inherit. We explore the science-and ethics-behind the movement.

Vegetables engineered with the gene-editing technology Crispr are moving closer to supermarket shelves. The U.S. Department of Agriculture has decided these genetically altered foods won't require a special label. But will they curry favor with consumers?

Lyme disease is rampant on Martha's Vineyard and Nantucket. MIT scientists believe that releasing genetically altered mice on the islands could curb-and even wipe out-the disease. A close look at an unprecedented environmental intervention.

In labs around the world, scientists are using gene-editing technology to revive species that disappeared from the face of the Earth long, long ago. In this episode, we talk to the researchers working on a project straight out of science fiction.

For decades, we've dreamt of an all-purpose robot that can cater to our every need. Silicon Valley is trying to catch up with that vision. One company is starting with a task already consuming our economy: home delivery.

The Apollo program to go to the moon marks the only time humans have left our home planet to set foot on another world. The biggest effect of this voyage was transforming the civilization it left behind.

What happens when an injury occurs on a commercial space flight or manned mission to Mars? Meet the scientists and astronauts studying how to keep us safe where routine care is impossible-and the closest hospital is a million miles away.

Self-assembly could be a boon for manufacturing in extreme and resource poor environments. Meet the scientist experimenting with the tech to develop adaptive materials and land masses.
