Daily briefing: How many elementary particles are there?

The Standard Model of particle physics identifies 17 elementary particles, a number that could expand significantly if new theories are confirmed. Estimates for the total number of fundamental particles, including hypothetical ones, range up to 995.5. In medical news, a man with paralysis has successfully used a brain-computer interface (BCI) in his home environment, demonstrating a significant step towards greater independence for individuals with severe motor impairments. Furthermore, research published this week suggests that GLP-1 receptor agonist drugs, commonly prescribed for obesity and type 2 diabetes, may also positively impact male reproductive health. These drugs appear to boost testosterone levels and improve sperm quality in men, according to preliminary findings.
