So you wanna build an aging company

Today, aging is cool. In 2024 alone, investors deployed about $8.5B into longevity-focused biotech companies. Aging biotech companies have entered clinical trials. The field has come a long way. But as “aging” (and “longevity”) have become more mainstream, there’s a temptation to stretch the definition to things that don’t belong in the category. Aging is not a single process. It’s a complex interplay of multiple biological processes that, over time, become dysregulated. Understanding it as suc

This Cough Syrup Ingredient Might Actually Slow Dementia

Today’s cough syrup could turn into tomorrow’s treatment for Parkinson’s disease. Recent research in the U.K. is the latest to suggest that a common ingredient in cough syrup, ambroxol, might be able to slow down the progression of Parkinson’s. Scientists at St. Joseph’s Health Care London conducted the year-long small study, which involved 55 patients with Parkinson’s-related dementia. The drug was safely tolerated and may have stabilized people’s symptoms, particularly people more genetically

My Mac contacted 63 different Apple owned domains in an hour, while not is use

During a one hour period today, my computer contacted 63 different Apple domains while i was not logged on and using it. I have been trying to minimize to the extent possible the reach of big tech into my life. A full 25% of the DNS queries from one of my computers (M2 MBA with macOS 15.4) are to Apple owned domains - even though my DNS provider (NextDNS) blocks Apple's native telemetry. Additionally, since I do not use Apple for my mail, contacts, calendars, podcasts or news, I already have th
