Fast radio bursts linked to massive galaxies

Scientists have discovered that fast radio bursts, or FRBs, are more likely to originate in massive, metal-rich galaxies, suggesting that these cosmic phenomena may be linked to the formation of magnetars through stellar mergers. The study in Nature used the Deep Synoptic Array-110 to analyze the origins of 30 FRBs, revealing a higher occurrence in large star-forming galaxies.

Mechanism behind the wet dog shake identified

The instinct to shake off when wet is common among many furry mammal species and is sparked by specific neurons that respond to touch and send signals from the back of the neck to the brain, according to a study in Science. The neurons, called C-fiber low-threshold mechanoreceptors, encircle hair follicles and are associated with pleasant sensations in response to a soft touch but also alert animals to water, dirt, a parasite or a drop of oil on their skin.

Human culture’s uniqueness lies in its flexibility

Research suggests that the unique aspect of human culture is its open-ended flexibility, not just its capacity for accumulation, according to a study in Nature Human Behaviour. The study highlights examples from animal cultures, such as tool-making in New Caledonian crows, to demonstrate that cultural accumulation is not exclusive to humans.

Study links tectonic activity to carbon emissions

New research explores the impact of tectonic activity on Earth’s carbon emissions and climate history. The study uses recent data on plate movements to model carbon dioxide release and capture over a billion years, underscoring the significant role of tectonic processes in shaping Earth’s atmospheric composition over geologic timescales.

Supersolid research breakthrough confirms dual properties

Scientists have successfully stirred a supersolid, a state of matter that exhibits both solid and superfluid properties, providing direct proof of its dual nature. This breakthrough involved creating quantized vortices, which are indicative of superfluidity, by using magnetic fields to rotate the supersolid.
