Researchers discover that tissue from the sea cucumber Psolus fabricii remains alive indefinitely in ordinary seawater, challenging conventional understandings of tissue decay and regeneration.
CienciaAIResearchers have identified a specific immune receptor in common bean plants that detects caterpillar saliva, triggering a distress signal to attract predatory wasps. Plants lacking this receptor showed significantly reduced defenses against caterpillars and failed to summon wasps.
CienciaAIUrban Australian male bowerbirds incorporate significantly more human-made items into their courtship displays than rural counterparts, with urban bowers having more decorations overall. Researchers from the University of Exeter observed differences in preferred materials, suggesting urbanization impacts bowerbird behavior and potentially sexual selection.
CienciaAIArchaeologists experimented with rhino teeth to see if Neanderthals used them as tools. The study found markings on ancient rhino teeth at archaeological sites similar to those made by using them as hammers for stone tool production, suggesting Neanderthals incorporated them into their toolkits.
CienciaAIMay's science roundup features a potential prehistoric copper smelting site in the Pyrenees, a new species of tiny blue octopus from the Galapagos, insights into why cats prefer silver vine over catnip, and a study suggesting political polarization behaves like a phase transition.
CienciaAIRising temperatures due to climate change are causing cognitive impairments in animals, leading to increased aggression, reduced learning abilities, and decreased vigilance. This affects species from birds and dogs to fish and insects, potentially disrupting ecosystems and risking species survival.
CienciaAIManhattanhenge, a twice-yearly phenomenon where the setting sun aligns with Manhattan's street grid, occurred on Thursday, with a fuller view expected on Friday, and repeats on July 11 and 12, attracting photographers and crowds.
