The Sun is a powerful source of radio emissions, to the point that, unlike most celestial sources, this emission dominates the system noise of many radio telescopes. The noise resulting from these sources is called “own noise”. Two recent papers analyze self-noise in maps of the Sun at radio frequencies formed using Fourier synthesis imaging…

Male-to-female poisoning of the same species, although rare, has been documented in all venomous taxa. While traditionally interpreted as a coercive mating strategy to enhance male reproductive success and prevent cannibalism, this explanation may not fully explain the behavior of scorpions, which exhibit minor sexual dimorphism in size and complex courtship rituals. This review explores…
When a Guinea baboon gets hold of the meat, who eats it next is not a matter of luck, but of loyalty. After nearly 10 years of observing wild Guinea baboons in Senegal, researchers discovered a hidden rule behind every meal. Published in a recent study in iSciencePrimates passed down meat not by chance but…

The world’s most prized coffee comes from partially digested beans pooped out by the Asian palm civet. Now, researchers are delving into why this “civet coffee” is so tasty. New chemical analyses of beans collected from civet poop, alongside beans picked directly from the coffee plants, suggest that fermentation in the civet’s innards does add…

If so, how could behavior like cooperation ever arise? From evolutionary biology to international diplomacy, we can model many situations using so-called game theory. These games have actions…
