How Has Roman Concrete Lasted for Millennia? A 1,900-Year-Old Latrine Offers New Clues About the Material’s Impressive Durability

A chemical process called carbonation, which helps seal cracks, could help explain why many ancient Roman structures are still standing today. Researchers hope that the insights will lead to better modern-day building materials

Earth is currently experiencing an occurrence of the El Niño climate pattern.

Could We Mitigate Super El Niños by Artificially Changing the Climate? A New Study Indicates Yes

Researchers used computer models to see what would have happened had scientists caused marine cloud brightening in the face of strong past El Niños

One of the most unusual public transportation systems in the world, the train hangs from an elevated steel track.

When Germany Built a Flying Train 125 Years Ago, a City Coalesced Beneath It. It Has Moved Royalty, Commuters and Tourists—and One Elephant—Ever Since

When there was no room on the ground, towns in the Wupper Valley looked to the skies and built a suspension railway that became a source of pride and connection

Cyborg Cockroaches Could Help Find Survivors of Natural Disasters. New Diving Suits Allow the Insects to Expand Their Search Underwater

Previously, researchers created electrical implants to control cockroaches’ movements for search-and-rescue missions. Now, they’ve made 3D-printed suits that provide oxygen, allowing the critters to survive submerged for up to three hours

To turn shrimp shells into a feedstock for hydrogen gas production, the process begins with mashing the shells into a rust-colored shrimp slurry.

How Shrimp Shells Are Being Turned Into ‘Carbon Negative’ Fuel, Food and Construction Materials

Engineers in Singapore have developed a new, multistep chemical process that transforms organic waste into useful, sustainable products

An image of Skylab captured by its final crew as they departed. During launch, one of the solar array wings broke off, and the gold sheet at the center was quickly manufactured afterward to serve as a makeshift sunshield and control the internal temperature.

America’s First Space Station Proved Humans Could Live and Work in Orbit for Months. Now, the Public Can See What It Looked Like in Person for the First Time in Eight Years

A backup version of Skylab was displayed when the Smithsonian’s National Air and Space Museum opened 50 years ago. After renovation of the building, the artifact is once more on view in a new gallery

Around two million graduating high school students in the United States—more than half—take the SAT each year.

100 Years Ago, Students Across the U.S. Took the First SAT. Today, Relatively Few Colleges Require the Test. Where Is It Headed?

The standardized exam has evolved over the past century, all in the name of testing for college readiness. Now, it has become a symbol of the American higher education system

Slow-healing wounds, especially in diabetics and burn victims, can become infected with antibiotic-resistant bacteria. Light-activated nanomaterials offer a potential new way to clear the infection and accelerate wound healing.

Scientists Are Using Nanomaterials to Heal Stubborn Wounds That Resist Antibiotic Treatment

Light-activated therapies may offer a solution to slow-healing lesions common in diabetics and burn victims

This drawing of a horse may have been Leonardo’s design for his planned equestrian monument.

500 Years Ago, Leonardo da Vinci’s Notebook Was Cut Up and Separated. Now, the Inventor’s Manuscripts and Drawings Are Reconstructed in an Online Archive

A new tool developed by Museo Galileo researchers has restored 50 pages from fragments excised centuries ago

Unlike metals such as iron and copper, gold doesn't easily tarnish. 

Glittering Gold Can Stay Shiny for Centuries. Scientists Say They’ve Figured Out Why the Precious Metal Is So Resistant to Tarnishing

When the metal is split, the atoms on its surface rearrange themselves into a very stable pattern that doesn’t easily react with oxygen in the air, a study suggests

Built roughly 4,600 years ago, the Great Pyramid of Giza has survived several significant earthquakes.

Ancient Egyptian Engineering Choices Helped the Great Pyramid of Giza Survive Earthquakes, New Research Finds

Researchers measured vibrations inside and around the pyramid to learn that the structure is surprisingly resilient against seismic tremors

The Bering Strait is a narrow waterway between Russia and Alaska that connects the Pacific and Arctic oceans.

Could Building a Dam Across the Bering Strait Save the Planet From Some Effects of Climate Change?

A preliminary study suggests that blocking off the waterway between Russia and Alaska could help the survival of a key system of ocean currents. But there could be potential unforeseen consequences, particularly to marine ecosystems

Scientists used acidic and basic solutions to trigger chemical reactions in algae.

These Marine Algae Glow When Waves Disturb Them. Their Bioluminescence Could Power Electricity-Free Lamps of the Future

The single-celled organisms usually shimmer for mere milliseconds, but researchers figured out how to sustain their illumination. The technology could one day be used to light robots’ ways in the deep sea or space

More than 50 million people suffer from epilepsy around the world, making it one of the most common and severe neurological disorders globally.

These Young Innovators Have Created a ‘Fitbit’ to Predict Epileptic Seizures

Truman Pierson and Christopher Fitz are developing behind-the-ear EEG patches and an accompanying app that issues an alert if the user is at high risk for a seizure in the next hour

Gustave Eiffel at the Eiffel Tower in 1889

A Dizzying Spiral Staircase With a Single Guardrail Once Led to the Top of the Eiffel Tower. Now, You Can Buy 14 of the Original Steps

The 1,062 steps connecting the tower’s second and third levels were installed in 1889. Fragments from the 137-year-old staircase can be found at several French museums

The Artemis 2 crew reported an issue with the toilet shortly after takeoff.

Artemis Astronauts Overcome Toilet Trouble and Officially Head Toward the Moon

Houston, we have a potty problem

Scientists have discovered that each of the sea star’s tube feet is driven independently using local feedback from the environment.

Sea Stars Can Lose an Arm and Soldier On. What If Robots Could Do the Same?

Bioinspiration looks to nature for clues on how to build more efficient, resilient robots

NASA’s Asteroid-Smashing DART Mission Changed a Space Rock’s Orbit Around the Sun, Marking a First for Humanity

Studying the 2022 collision’s effects can help scientists protect the Earth from celestial objects that might head toward us

Swimmable Cities is a global alliance of local government officials, experts and advocates working to make urban waterways clean enough to swim in.

Would You Jump Into Your Local River? Swimmable Cities May Be Within Reach as Once-Polluted Waterways Are Restored

Efforts to improve the “swimmability” of urban areas are gaining global traction, from Paris to Chicago
