There was no group difference in reaction times and accuracy between males and females (using contraception and not). However, within subject analyses revealed that regularly menstruating females performed better during menstruation compared to being in any other phase, with faster reaction times (10ms c.ca, p < .01), fewer errors (p < .05) and lower dispersion intra-individual variability (p < .05). In contrast they exhibited slower reaction times (10ms c.ca, p < .01) and poorer timing anticipation (p < .01) in the luteal phase, and more errors in the predicted ovulatory phase (p < .01). Self-reported mood, cognitive and physical symptoms were all worst during menstruation (p < .01), and a significant proportion of females felt that their symptoms were negatively affecting their cognitive performance during menstruation on testing day, which was incongruent with their actual performance.

Scientists Find Plastic-Eating Fungus Feasting on Great Pacific Garbage Patch

The perception of taste is remarkably complex, not only on the tongue but in organs throughout the body.

The idea that specific tastes are confined to certain areas of the tongue is a myth that “persists in the collective consciousness despite decades of research debunking it.” Also wrong: the notion that taste is limited to the mouth.

Makes me sad it's being sold instead of studied. "For Profit Paleontology" leaves a bad taste in my mouth.

New paper casts doubt on the often reported huge rise in maternal deaths in the United States over the past 20 years. They put the blame firmly on a change in the reporting method.

Sources, a few more items and relevant Wikipedia articles are in 2024 in science.

Now making these quarterly instead of monthly (posted most of the previous ones only to reddit). I’m making these summaries so you can stay up to date with the latest science even if you only have little time. Also updating Wikipedia articles sooner or later.

This study has identified the anterior cingulate cortex (ACC) as a key area in the brain responsible for sensory hypersensitivity in autism spectrum disorders. Utilizing a mouse model with a Grin2b gene mutation, heightened neural activity and connectivity in the ACC was observed. Suppressing this hyperactivity normalized the sensory hypersensitivity, offering new insights into treatment options
