The Louvre in Paris has its own particle accelerator for art analysis

Scientists used mass spectrometry to determine the materials in a 1690 painting

Previously used to map the distribution of molecules on biological tissue samples, researchers combined the technique with machine learning to uncover six layers of pigments, binders, and a thin gold leaf layer within *The Marriage of the Virgin*, from a collection in the Metropolitan Museum of Art. The technique may help identify and track artists' material use to learn about pieces of unknown provenance. (Some readers may experience a paywall.)

A particle accelerator allowed researchers to noninvasively examine a mummy

The mummy hailed from the Faiyum oasis, where Egyptian and Roman cultures intersected, and was analyzed using the Advanced Photon Source at Argonne National Laboratory. The device used high-energy X-rays to probe the material composition of numerous objects embedded deep inside the mummy without damaging its remains.

Particle accelerators have been used to reveal detailed ant anatomy

Using a synchrotron facility at the Karlsruhe Institute of Technology in Germany, a pair of X-ray beams swept across about 2,200 ant specimens to create over 200 terabytes of projection images from multiple angles. The images were compiled into micrometer-resolution 3D reconstructions of 792 species, which are freely accessible on the Antscan platform.

Particle accelerators detect subatomic particles using millions of sensors

Calorimeters measure the energy of particles. Tracking devices can measure momentum and charge from the trajectory of particles, which is determined by recording tiny electrical signals. Time-of-flight detectors provide particle velocities directly and particle mass indirectly, giving physicists a suite of properties to compare with those of known matter.

Take a 360-degree tour of the particle detector at the Large Hadron Collider

The ATLAS experiment integrates concentric layers of sensors to analyze the properties of particles that emerge from the collisions of accelerated matter. More than 3 petabytes of data—equivalent to 600 years of music—can be expected to be collected from this experiment yearly (VR device-compatible).

As of 2023, the world's smallest particle accelerator is smaller than a penny

The prototype is an example of a photonic accelerator, which utilizes tiny lasers to accelerate electrons rather than relying on oscillating electromagnetic fields to move them. It can deliver about 1 electron per second with energies equivalent to those found in cathode-ray tube televisions.

Why can't we see Mona Lisa's eyebrows?

The world's most famous painting is missing something. And it took centuries for experts to figure out what. In this episode, August Moon investigates what happened to the Mona Lisa's eyebrows—analyzing infrared scans, tracking 500 years of restoration, and examining a forgotten copy from Leonardo's studio. But he uncovers something bigger: what we lost after the 1911 theft that has nothing to do with the painting leaving the Louvre.

A facility at CERN is dedicated to creating and analyzing anti-hydrogen

Dubbed the "antimatter factory," the site was built to study the properties of dark matter and identify any inconsistencies with existing particle physics models. Antimatter particles have the same mass as normal matter, but opposite charge and other quantum properties.

The Mona Lisa's celebrity status and repeated restorations have obscured what made the painting so revolutionary for its time

Americans touring the Louvre were inspired to create their own grand museums

The one-time royal residence was first transformed into a public museum in 1793 amid the French Revolution. Americans visiting in the early 1800s were both turned off by the aristocratic grandeur and compelled by the open access to the public. James Fenimore Cooper, the author of "The Last of the Mohicans," apparently came and measured the length of galleries.

In 2025, thieves stole roughly $100M of jewels from the Louvre

The robbery of the world's most visited museum took less than ten minutes and resulted in worldwide shock. The thieves used a ladder to break into the building and steal eight pieces of French crown jewels, and then escaped on motorbikes.

Items in the Curie Museum do not produce significant radioactivity today

Ionizing radiation produced by elements such as uranium, polonium, and radium can damage living things, but the trace amounts found in the museum objects that Marie Curie once touched have been largely decontaminated, with more dangerous items stored in protective, lead-lined containers.

Flip through centuries-old artifacts in this 3D library

Archaeology is hands-on work, giving researchers the ability to analyze artifacts from as many sides as possible to find marks left by those that came before us. While looking at pictures of artifacts gives you some insight, you're limited to...

In 1971, a $35 ferret helped clean the Fermi National Accelerator Laboratory

Lacking cleaning robots, Fermilab scientists purchased a ferret named Felicia when metal slivers obstructing accelerated particles were identified. They trained her to run strings through vacuum tubes more than 90 meters long, and cleanser-dipped swabs were then tied to the strings and pulled through to remove the debris.

Museums are updating their approach to wall texts amid 8-second-long attention spans

The explanatory text found next to art in museums has long been integral to the exhibit experience, helping provide context for artists, the piece, and cultural movements. Some institutions are removing the texts to allow visitors to interpret the pieces unaided; others are seeking to optimize length or recruit a variety of perspectives—called "labelists"—to offer less authoritative context for the pieces.

Meet the Dutch art detective who's recovered a Van Gogh, Dali, and Picasso

Known by some as the "Indiana Jones of the art world," Arthur Brand has recovered more than 150 stolen paintings and artifacts. He works independently, existing as a helpful bridge between the police and the people who might know where the stolen art is hiding. He is motivated by the thrill of the chase more than any financial payoff.

Scientists have tested atmospheric models by firing rockets into the aurora borealis

Functioning like components of a CT scan, the missiles transmit signals that can be used to identify charged particles and electromagnetic currents in slices. The slices are then combined to construct a computer-based model of Earth's atmospheric structure, which is used to compare the accuracy of physics-based models.

In 2015, a custom virus program was used to destroy and transform art images

At the Art Laboratory Berlin's "bOdy pandemOnium: Immersion into Noise" exhibit, Chicago-born artist Joseph Nechvatal explored viractualism—the interface between the biological and the technological—via a custom virus program that randomly altered images representing the human eye and rectum.

How scientists determine elemental composition based on the light emitted by cooling atoms

When electrons within an atom drop to a lower energy level closer to the nucleus, they lose energy and produce light with energy equal to the difference between the two energy levels. Because these levels and the corresponding emitted light are unique to each element, the light serves as a unique signature that can be compared to known lab samples for identification.
