High-Fat Diets in Adolescence Linked to Adult Impulsivity

Adolescent rats fed a high-fat diet displayed increased impulsivity and altered decision-making as adults. These "cheesecake rats" were quicker to act on visual cues (indicative of impulsivity) but showed more conservative choices in gambling tasks, opting for smaller, safer rewards.

New Sensor Lights Up Path to Early Alzheimer’s Diagnosis

Researchers introduced a novel fluorescence imaging technique that can detect amyloids, key biomarkers in neurodegenerative diseases like Alzheimer’s and Parkinson’s, offering a simpler alternative to PET scans. This method utilizes a sensor array of coumarin-based molecular probes, capable of illuminating amyloids to monitor disease progression or distinguish between different conditions.

Children’s Dislike of Cauliflower and Broccoli Could Be Written in Their Microbiome

Children whose saliva produced high amounts of sulfur volatiles disliked raw Brassica vegetables the most. The levels of sulfur volatiles were similar in parents and children, suggesting a shared oral microbiome. However, the relationship between sulfur volatiles and the dislike of Brassica vegetables was not as high in adults, suggesting they may have learned to tolerate the taste of the vegetables over time.

Exploring why some COVID-19 patients lose their sense of smell

ACE2 and TMPRSS2, two proteins required for SARS-CoV-2 entry, are produced in cells in the nasal cavity that contribute to odor detection. The findings may explain why people with coronavirus often describe the loss of the sense of smell as a symptom of the virus.
