Daily briefing: How mantis shrimps survive landing the world's fastest punch
Briefly

The peacock mantis shrimp can deliver a punch strong enough to crack crustacean shells without harming itself, due to the specialized dactyl club limb that absorbs shockwaves. Research reveals that this multi-layered structure could influence the design of new artificial materials. In another study, scientists engineered nasal bacteria, Lactobacillus plantarum, to deliver appetite-suppressing hormones to the brains of obese mice, promoting weight loss. Additionally, OpenAI introduced a tool for synthesizing research, which has faced scrutiny over its output quality compared to that of a human.
The punching limb, called the dactyl club, has a multi-layered structure that allows it to absorb shockwaves, enabling mantis shrimp to punch without injury.
The findings about mantis shrimp could inspire the design of artificial materials, with properties that mimic their shock-absorbing capabilities.
Researchers engineered bacteria from the nasal microbiome to potentially deliver drugs to the brain through appetite-suppressing hormones in obese mice.
OpenAI's new deep research tool can synthesize information from numerous sources but has been critiqued for not reaching the expected output quality of a human.
