signs of machine involvement. Balancing Integrity and Innovation The reliance on AI in publishing has reached a point where even high-profile venues like the NeurIPS conference have struggled to filter out papers containing hallucinated citations. In...

face distinct challenges that dictate how artificial intelligence is applied. For martensitic steels and titanium alloys, where near-full density is relatively easy to achieve, researchers use explainable models to regulate microstructural...

from the Big Bang through the present and into the unknown future. This intuition underpins our understanding of causality, where every action precedes its consequence. However, a growing cohort of theoretical physicists and philosophers are challenging...

they tend to engage in exploratory behaviors to regain control over their careers. The data supported a sequential chain where technology use increases substitution risk, which in turn raises job insecurity, ultimately leading to greater career...

from Del Bufalo. The scholar had documented the artifact as a lost treasure, stolen from the records of antiquity, and here it was, reportedly gracing a living room floor just blocks away. Two millennia after it served as a floor on a Roman emperor’s...

placed inside. Jacobs famously addressed his future audience: “The world is engaged in burying our civilization forever, and here in this crypt we leave it to you.” Though the crypt drifted from public consciousness for decades, it was rediscovered in...

shifts in cumulative disease incidence across urban, peri-urban, and sylvatic forest patches. In the forest cycle, where the virus circulates among non-human primates and wild mosquitoes, reproduction rates among animals dictate nearly all the variation...

comes into play when the Moon is near the horizon. Because its light must travel through a thicker layer of Earth’s atmosphere, the shorter blue wavelengths are filtered out, leaving the vibrant yellow and orange tones that characterize a rising moon....

Five planets will align in the September night sky, offering a rare opportunity to spot multiple worlds across our solar system. Don’t miss the view. September promises a spectacular display for amateur astronomers, with five major planets—Mercury,...
