It’s a constant challenge to cover all the fascinating scientific discoveries that emerge each month. To address this, we’re presenting a monthly “Research roundup: 6 cool science stories we almost missed.” This month’s compilation includes a diverse range of topics, from the structural differences between regular and gluten-free spaghetti to the formation of gullies on Mars, the age of Egypt’s Karnak Temple, and even a computational proof for the highest possible scoring Boggle board.

Background Context
Sometimes, intriguing research projects come to our attention through reader submissions. One such project involves the classic word game Boggle, where players create words from a 4×4 grid of lettered dice. Software engineer Dan Vanderkam shared a preprint detailing his successful attempt to find the Boggle board configuration with the highest possible score. This research is part of our “Research roundup: 6 cool science stories we almost missed,” showcasing unique and interesting findings.
Vanderkam’s computationally proven highest-scoring Boggle board yields 3,625 points and contains over 1,000 possible words, with “replastering” being the longest. Vanderkam documented his process, including the code used, on his blog. While he jokingly admitted to the Financial Times that he might be the only person truly interested in this problem, a 1982 attempt found an optimal board yielding 2,195 points. Vanderkam’s solution involved grouping board configurations with similar patterns and using a “branch and bound” technique to discard less promising options, rather than individually calculating scores for each board. This Boggle research is a fun inclusion in our “Research roundup: 6 cool science stories we almost missed.”
Uncovering the Origins of Karnak Temple
The Karnak Temple complex in Egypt, located near Luxor, has captivated archaeologists and tourists for years. However, its precise age has been debated. A recent geological survey is providing new insights into the temple’s origins and evolution, according to a paper published in the journal Antiquity. This discovery is a fascinating addition to our “Research roundup: 6 cool science stories we almost missed.”
Researchers analyzed sediment cores and ceramic fragments from the site to reconstruct the changing landscape. Their findings suggest that the site experienced regular flooding from the Nile around 2520 BCE. Consequently, the earliest permanent settlement at Karnak likely emerged between 2591 and 2152 BCE, coinciding with the oldest ceramic fragments. River channels created an island of higher ground, serving as the foundation for the temple’s construction. Over millennia, as these channels diverged, the temple complex expanded. Co-author Ben Pennington suggests that the Theban elites may have chosen Karnak’s location to represent the cosmogonical scene of high ground emerging from water, aligning with Egyptian creation myths. This exploration of Karnak’s origins makes it a compelling part of our “Research roundup: 6 cool science stories we almost missed.”
Solving the Mystery of Martian Gullies
Mars possesses numerous intriguing features, including the sinuous gullies found on some of its dunes. Two primary hypotheses exist regarding their formation. One suggests they result from debris flow during a period when liquid water may have existed on the planet’s surface. The other proposes that the gullies form due to the seasonal deposition and sublimation of CO2 ice. This Martian puzzle is included in our “Research roundup: 6 cool science stories we almost missed.”
A paper published in Geophysical Research Letters presents strong evidence supporting the latter hypothesis. Building on previous research on how CO2 ice sublimation can drive debris flows on Mars, earth scientist Serina Diniega and her team conducted experiments using a large rotating drum filled with CO2 ice and sand. By manipulating the drum’s rotation speed and angle, they simulated Martian surface conditions. The experiments revealed that CO2 ice sublimation can indeed trigger debris flows, creating gullies similar to those observed on Mars. This discovery provides valuable insight into the geological processes shaping the Martian landscape and earns its spot in our “Research roundup: 6 cool science stories we almost missed.”
Additional Cool Science Stories
Beyond the Boggle board, Karnak Temple, and Martian gullies, our “Research roundup: 6 cool science stories we almost missed” includes other fascinating discoveries. One study delves into the microstructural differences between regular and gluten-free spaghetti, offering insights into how these pasta varieties behave during cooking. Another story captures striking snakes in action, providing unique perspectives on their movement and behavior.
These additional stories, along with the ones detailed above, highlight the breadth and depth of scientific research being conducted across various fields. Our goal with this “Research roundup: 6 cool science stories we almost missed” is to bring these intriguing findings to a wider audience, sparking curiosity and promoting a greater appreciation for the world around us.
In conclusion, this “Research roundup: 6 cool science stories we almost missed” showcases a diverse range of scientific endeavors, from optimizing Boggle boards to unraveling the mysteries of ancient temples and Martian landscapes. These stories exemplify the ongoing quest to understand our world and beyond, and we hope they have sparked your interest in the wonders of science.
