Near-complete skull discovery reveals ‘top apex’, leopard-sized “fearsome” carnivore

A nearly complete skull of the ancient apex carnivore Bastetodon has been discovered in the Egyptian desert, revealing a new species of hyaenodonta. The discovery sheds light on the evolution of hyaenodonts and their global distribution, with findings suggesting they spread from Africa to Asia, Europe, India, and North America.

Opportunistic car recalls could damage brands

Research from Edith Cowan University found that opportunistic recalls, where dealerships try to upsell during the process, lead to negative brand personality and protest behavior. However, protests can paradoxically strengthen customer loyalty if companies effectively manage the recall issue and engage with customers.

Ushering in the era of a 1,000-km driving range for electric vehicles! DGIST has successfully developed high-capacity high-safety anode materials

Researchers at DGIST have developed high-capacity, high-safety anode materials that can significantly increase the driving range of electric vehicles. By setting a high initial activation charging voltage, they prevented nano-cracks and structural collapse, leading to improved battery performance and safety.

Low-cost and efficient consistency with adaptive synchronization for metadata replication

A new consistency framework with adaptive synchronization is proposed to improve metadata operation performance and scalability. The framework decoupled directory from file metadata and uses different synchronization methods for directory trees and file metadata, enabling fine-grained tracking of access conflict status.

Marine mystery solved: How anemonefish avoid stings from their sea anemone hosts

Researchers have discovered that anemonefish have evolved to maintain very low levels of sialic acid in their skin mucus to avoid triggering the release of nematocysts in their sea anemone hosts. This adaptation allows them to safely coexist with sea anemones, which also lack these sugar compounds in their own mucus.
