5. Octopuses seen hunting together with fish, punching those that don’t cooperate
Total comment counts : 25
Summary
A recent study published in Nature reveals that the Octopus cyanea, or day octopus, hunts in groups with various fish species, challenging previous beliefs that octopuses are solitary creatures. Researchers observed these octopuses organizing hunting efforts, indicating a level of social intelligence comparable to vertebrates. They tracked 13 octopuses over 120 hours near Eilat, Israel, noting that the octopuses would “punch” fish partners to maintain social order and enforce task adherence during hunts. This suggests that octopuses benefit by following fish to food, while fish profit from the octopus’s ability to reach prey hidden in crevices. The study raises questions about whether octopuses form bonds with specific fish companions and whether this behavior is learned or instinctual. Overall, it highlights the complex social lives of these cephalopods and their cognitive abilities.

6. Eliminating Memory Safety Vulnerabilities at the Source
Total comment counts : 16
Summary
Memory safety vulnerabilities pose significant risks to software security. Google advocates for a “Safe Coding” approach, emphasizing the transition to memory-safe languages to reduce these vulnerabilities over time. This shift has shown promising results, notably in Android, where the percentage of memory safety vulnerabilities decreased from 76% to 24% over six years.
The article highlights an important principle: vulnerabilities decay over time, with newer code being more prone to issues. This means that as new development moves towards memory-safe languages, the overall number of vulnerabilities in the codebase can actually drop, even if the total amount of code written in memory-unsafe languages increases.
Data from 2024 indicates a continued decline in memory safety vulnerabilities, despite much of the codebase remaining memory unsafe, suggesting that older code tends to have lower vulnerability densities. The trend aligns with efforts starting around 2019 to prioritize memory-safe languages amid rising costs and complexities associated with managing memory safety issues.
Historically, the industry’s strategies have evolved from reactive patching to proactive mitigations, but scalable and sustainable solutions are still necessary. As memory safety vulnerabilities decrease, the overall security risk diminishes, underscoring the effectiveness of prioritizing Safe Coding practices in software development.

10. Italian Music Through the Lens of Complex Networks
Total comment counts : 13
Summary
The article discusses a research project that explores the interconnectedness of contemporary Italian music, focusing on Gianni Maroccolo’s influence. The author was inspired to analyze collaborations within Italian music after a conversation with a non-Italian. Over the course of a year, they compiled a network of nearly 2,500 Italian bands from 1902 to 2024 using data from Wikipedia and Discogs, creating a bipartite network linking artists to their bands.
The research examines two projections of this network: one connecting bands that share musicians and another analyzing artist collaborations. The findings indicate that the network is structured by time and genre, with significant activity in Italian music occurring from the late 1960s to the early 1980s. Despite initially positing Maroccolo as a central figure, the analysis reveals that he is not among the top ten central artists in terms of collaboration. Instead, Paolo Fresu emerges as a more prominent figure in Italian music. The findings were published in the journal Applied Network Science.
