Underwater archaeologists find mysterious bone fragments in a 500-year-old shipwreck off the coast of Sweden. What could they belong to?

The Age of Exploration and Europe’s imperial colonization of far-off lands was launched by a revolution in ship design that made long-distance voyages practical. A newly discovered 500-year-old wreck offers vital clues to this momentous innovation.

As electric vehicle technology takes off—literally—how will the logistics of air traffic work? Watch how NASA researchers are writing the rules that will make air travel via electric vehicles safe.

Can new emission-free electric planes replace our polluting airliners and revolutionize personal transportation in our cities? NOVA takes a ride in some quiet, energy-efficient, prototypes that are vying for success as electric flight takes off.

Newly analyzed amateur footage of the crash shows the airship’s final seconds from a fresh angle—allowing historians for the first time to see the airship from nose to tail just after the fire breaks out.

80 years after the world’s largest airship ignited in a giant fireball, newly discovered footage sparks a reinvestigation of what exactly caused the Hindenburg disaster.

Mia Fassi’s infertility journey started when she was in her mid-30s. After unsuccessful in vitro treatments, adopting a child felt like an easy transition to consider.

Trystan Reese felt grateful that he was able to become pregnant and give birth. But for parents about to transition, there are steps they can take to preserve their fertility.

At 39, Brigitte Adams became an early adopter of egg vitrification, a technology that can dramatically improve the preservation of a woman's eggs and, potentially, her future fertility.
Here’s her story.

Black women have experienced long-standing social, economic, and environmental stress that leads to more adverse reproductive health outcomes.

What causes infertility, and how can assisted reproductive technologies help? Follow the journeys of people navigating fertility challenges from structural inequalities and racism to falling sperm counts, egg freezing, and IVF.

Some corals, called "super corals," are more resistant to temperature changes and bleaching. Discover how scientist Ruth Gates began a "super coral" breeding program to create more resilient reefs.

If oceans continue to warm at the current pace, coral reefs could be wiped out by the end of the century. But scientists from around the globe are rushing to help corals adapt to a changing climate through assisted evolution.

A scientist gives a test to her students: Affiliate male and female names equally—and as quickly—with science terms. Here are the results.

Women face widespread discrimination in science. Chemist Dr. Raychelle Burks discusses the additional challenges for those with intersectional identities.

Discover how the metaphor of an iceberg can help depict the various forms of sexual harassment affecting women in STEM.

Women make up less than a quarter of STEM professionals in the United States, and numbers are even lower for women of color. But a growing group of researchers is exposing longstanding discrimination and making science more inclusive.

Get a guided tour of the first Mars rover landing captured on video from NASA Jet Propulsion Laboratory engineer Ian Clark.

The spacecraft has to be extremely clean. The entire spacecraft—that includes the rover, the heat shield, the descent stage, and back shell—must contain less than 500,000 bacterial endospores, or spores. Just to give you an idea, a teaspoon of seawater has ten times more bacteria.

This NASA rover landed on Mars, more than 130 million miles from Earth. It’s task? To continue the search for past life on the red planet.
