By comparing differently tuned glomeruli, this work shows that the brain uses different circuit layouts for specialised vs general smells, offering new insight into how odour meaning is encoded.

It costs ~$70 to produce a year’s supply of insulin.
Yet, the average annual cost of insulin went from $2,864 in 2012 to $5,705 in 2016 to $18,000 in 2025. A 25,714% markup. That isn’t inflation or supply chain—It’s corporate greed.
Now—California will sell insulin for $11. Make this nationwide!
