Humans, Not Glaciers, Moved Stones to Stonehenge: A Definitive Answer?
Stonehenge, a UNESCO World Heritage site, continues to captivate researchers and tourists alike. Recent chemical analyses have pinpointed the origins of the stones, revealing they were sourced from quarries located considerable distances away. The long-standing question of how these massive stones were transported to their current location has fueled debate for decades. Was it the power of glacial movement, or the ingenuity of prehistoric humans?
Mineral Fingerprinting Reveals Human Transport
Previously, theories suggested glaciers transported the bluestones from Wales to Salisbury Plain. However, a new study published in Communications Earth & Environment provides the strongest evidence yet supporting human transport. Researchers at Curtin University, led by Anthony Clarke, employed mineral fingerprinting techniques to analyze hundreds of zircon crystals collected from rivers near Stonehenge. They sought evidence of Pleistocene-era sediment – a distinct mineral signature that would be present if the stones had been “sailed” north by glaciers.
Crucially, this signature was absent. Furthermore, Clarke’s team discovered the Stonehenge Altar Stone originated from the Orkney region in northeast Scotland, not Wales, adding another layer to the complexity. This finding strongly suggests human intervention was responsible for the stones’ journey. The absence of the expected sediment signature makes glacial transport far less likely.

When Grasshoppers Fly: Bio-Inspired Robotics for Enhanced Flight
Grasshoppers are masters of both terrestrial and aerial locomotion, seamlessly transitioning between hopping, flapping, jumping, and gliding. This remarkable ability has inspired scientists at Princeton University to develop a novel approach to robotic wing design. Their research, published in the Journal of the Royal Society Interface, could pave the way for miniature robots with extended flight times and multimodal locomotion capabilities.
Decoding Grasshopper Wing Aerodynamics
Grasshoppers possess two sets of wings: forewings for protection and camouflage, and hindwings for flight. The hindwings are corrugated, allowing them to fold neatly into the insect’s body. The Princeton team utilized CT scans to capture the precise geometry of grasshopper wings and then 3D-printed model wings with varying designs. These models were tested in a water channel to analyze water flow, isolating key features like wing shape and corrugation to determine their impact on aerodynamic performance.
The resulting glider, designed based on these findings, performed as well as a real grasshopper in flight tests. Interestingly, the study revealed that smooth wings offer more efficient gliding. The researchers hypothesize that the corrugations in real grasshopper wings evolved to facilitate steeper angles of attack, providing greater maneuverability. This research highlights the power of biomimicry in robotics.

Lip-Syncing Robot: Bridging the Uncanny Valley
Humanoid robots are becoming increasingly sophisticated, but achieving truly human-like expression remains a significant challenge. A key factor is the limited range of facial gestures, particularly lip motion, which contributes to the “Uncanny Valley” effect. Engineers at Columbia University have made a breakthrough with a robot capable of learning facial lip motions for both speaking and singing. Their work, published in Science Robotics, resulted in a robotic face that can articulate words in multiple languages and even perform AI-generated songs (its debut album, aptly titled hello world, is available now!).
Flexible Materials and Mirror Learning
The Columbia team overcame the rigidity of traditional robotic faces by constructing theirs from flexible material augmented with 26 motors (actuators). The robot learned to coordinate its facial movements by observing itself in a mirror while attempting thousands of random expressions. This iterative process allowed it to achieve specific facial gestures. The next step involved training the robot on recorded videos of humans speaking and singing, utilizing an AI algorithm to map human mouth movements to the robot’s actuators.
While the lip-syncing isn’t perfect – the robot still struggles with “B” and “W” sounds – the authors are optimistic about future improvements. Integrating this technology with large language models like ChatGPT or Gemini could further enhance its lip-syncing accuracy and conversational abilities. This represents a significant step towards more natural and engaging human-robot interaction.

Is Leonardo’s DNA Preserved in His Art? The Arteomics Revolution
The quest to understand Leonardo da Vinci’s life and work has taken a fascinating turn. In 2020, researchers discovered unique microbial communities on his drawings. Building on this, the Leonardo da Vinci DNA Project in France has been analyzing swabs from centuries-old artwork, concluding that microbial signatures can differentiate art based on materials – a field they’ve termed “arteomics.” The project has also meticulously reconstructed Leonardo’s family tree, spanning 21 generations.
Sequencing DNA from Leonardo’s Artifacts
The latest development, posted as a preprint on bioRxiv, announces the successful sequencing of human DNA collected from artifacts associated with Leonardo, including a drawing potentially attributed to him and letters from family members. The team lightly swabbed the surfaces and recovered Y-chromosome sequences from several samples. These sequences are related, and the authors speculate some may even belong to Leonardo himself, though definitive confirmation requires comparison with samples from his grave, notebooks, and family tomb.
Beyond human DNA, the samples also contained genetic material from bacteria, fungi, flowers, animals, viruses, and parasites, offering a glimpse into the environment surrounding Leonardo and his art. This research opens up exciting possibilities for understanding the past through the lens of molecular archaeology.

From Pint to Plate: Brewer’s Yeast as a Sustainable Scaffold for Lab-Grown Meat
Lab-grown meat holds promise as a more sustainable alternative to traditional agriculture, but challenges remain in replicating the texture and mouthfeel of real meat. A new approach, published in Frontiers in Nutrition, utilizes spent brewer’s yeast – a byproduct of beer production – to create edible “scaffolding” for cultivating meat in the lab.
Spent Yeast: A Sustainable and Texturally Superior Scaffold
Traditionally, nutrient broth is used to grow the bacterial cellulose that forms the scaffold. However, researchers at University College London discovered that using spent brewer’s yeast to culture a cellulose-producing bacteria resulted in a material with a texture much closer to real meat. They tested the mechanical and structural properties of the cellulose using a “chewing machine,” confirming its superior texture. The next steps involve incorporating fat and muscle cells into the scaffold and exploring the use of yeast from different beer varieties. This innovative approach offers a sustainable solution for improving the quality and appeal of lab-grown meat.

Water-Driven Gears: A Novel Approach to Robotic Motion
Gears have been fundamental to mechanical systems for millennia, dating back to ancient China. However, traditional gears are often inflexible and prone to breakage. Researchers at New York University have explored an alternative: using flowing water to create gear-like motion without the need for teeth. Their findings, published in Physical Review Letters, could lead to more robust and adaptable robotic structures.
Fluid Dynamics Mimic Gear Function
The NYU team immersed cylindrical rotors in a glycerol-and-water solution. By rotating one cylinder, they induced rotation in a passive cylinder, mimicking the function of gears. When the cylinders were close together, the flow patterns resembled those of interlocking gear teeth. Increasing the distance between the cylinders caused the active cylinder to rotate faster, creating a “belt and pulley” effect. This demonstrates that fluid dynamics can effectively replicate the mechanical advantages of traditional gears, offering a potentially more resilient and adaptable solution for robotic applications. This builds on the lab's previous work on bubbles, hula hoops, and even reverse sprinkler systems.
