Research Roundup: Six Cool Science Stories We Almost Missed

Reviving Edison’s Battery Design

At the turn of the 20th century, electric vehicles (EVs) powered by lead-acid batteries were more prevalent than their gas-powered counterparts. However, as technology advanced, the internal combustion engine took the lead due to the limitations of these batteries, which offered a mere 30-mile range. Thomas Edison proposed a nickel-iron battery that could potentially extend this range to 100 miles, with long life and reasonable recharging times.

Recently, an international team of scientists has revived Edison’s concept, creating a modern version of the nickel-iron battery. Their research, published in the journal Small, draws inspiration from natural processes, specifically how shellfish and animals form their hard outer shells and bones. The team utilized beef byproduct proteins combined with graphene oxide to create a scaffolding for the battery.

Through a process involving superheating and high-temperature baking, the proteins charred into carbon, resulting in a structure that limited the nickel and iron clusters to less than 5 nanometers. This design significantly increased the surface area for chemical reactions, leading to a prototype that recharged in seconds and endured over 12,000 cycles—equivalent to about 30 years of daily use.

Despite its impressive longevity, the battery’s storage capacity remains below that of current lithium-ion batteries. While this may limit its application in powering EVs, the authors suggest it could be ideal for storing excess electricity generated by solar farms and other renewable energy sources.

Vanishing Star Becomes a Black Hole

In 2014, NASA’s NEOWISE project detected an unusual brightening of infrared light from a massive star in the Andromeda galaxy, which was confirmed by several telescopes. By 2016, the star had dimmed significantly, effectively “vanishing” from sight, akin to Betelgeuse suddenly disappearing. This phenomenon has intrigued astronomers, leading them to investigate the star’s fate.

A team of astronomers analyzed archival data and concluded that this star underwent a direct collapse into a black hole without the typical supernova phase. Their findings, published in the journal Science, suggest that the star’s core formed a dense neutron star, but the shock wave usually associated with supernovae was insufficient to expel all stellar material.

Instead, the outer layers of gas, influenced by convection currents, were ejected, allowing the core to collapse directly into a black hole. This discovery could indicate a new class of stars that do not undergo supernovae, making them harder to detect. The faint afterglow of these stars, detectable in mid-infrared wavelengths, provides a new avenue for astronomical research.

Smart Underwear Measures Flatulence

Flatulence is a natural bodily function, but for those with digestive issues, it can be a significant concern. Currently, physicians lack reliable methods to quantify daily gas production, complicating the diagnosis of gastrointestinal conditions. Researchers at the University of Maryland have developed an innovative solution: “smart underwear” designed to measure flatulence.

This technology, detailed in a paper published in Biosensors and Bioelectronics, involves a small device equipped with electrochemical sensors that attaches to the underwear. The sensors continuously track gas emissions, even during sleep, providing a comprehensive overview of the wearer’s flatulence patterns.

Previous studies relied on small sample sizes and self-reported data, often leading to inaccurate estimates. The smart underwear study revealed that healthy adults pass gas an average of 32 times per day, significantly higher than previously reported figures. This research aims to establish a baseline for normal flatulence, correlating it with diet and microbiome composition through a larger sample size in the Human Flatus Atlas program.

Neurons Playing Doom: A New Frontier in Neuroscience

In an unexpected intersection of neuroscience and gaming, researchers have successfully created a dish of neurons that can play the video game Doom. This groundbreaking study explores the potential of using biological neural networks to understand brain function and artificial intelligence.

The research, which has garnered significant attention, demonstrates how neurons can be trained to respond to stimuli in a way that mimics decision-making processes. By connecting the neurons to a computer interface, researchers were able to observe how these biological systems interact with digital environments.

This innovative approach not only sheds light on the fundamental workings of the brain but also opens up new possibilities for developing AI systems that mimic biological processes. The implications of this research could extend to various fields, including robotics, cognitive science, and even game development.

AI Discovers Rules of an Ancient Game

Artificial intelligence continues to push boundaries in various domains, including archaeology. A recent study revealed that AI has successfully uncovered the rules of an ancient game known as “Senet,” which dates back to ancient Egypt. This board game, believed to be one of the oldest known, has puzzled historians for decades due to the lack of comprehensive documentation on its rules.

Using machine learning algorithms, researchers analyzed patterns in the game’s artifacts and reconstructed its rules. The AI’s ability to identify and interpret complex patterns has provided new insights into the cultural significance of Senet and its role in ancient Egyptian society.

This application of AI in archaeology not only enhances our understanding of historical games but also demonstrates the technology’s potential in deciphering other ancient texts and artifacts. The intersection of AI and history could lead to significant advancements in how we interpret and understand our past.
