Blocking a single immune signal made old mice act young again. The study points to neutrophils that fail to clear away as a driver of aging, which is a more specific target than most anti-aging research offers.

Lithium for Alzheimer's and aging immune signals
Today's health news is split between two threads: the tantalizing possibility that low-dose lithium could prevent Alzheimer's, and a deeper look at the biological processes driving aging. A mouse study suggests blocking a single immune signal can reverse age-related decline, while a human trial for lithium is on the horizon. The rest of the day is a mix of practical concerns, from hot drinks and cancer risk to the fallout from GLP-1 weight regain.
Aging and Alzheimer's
Two very different approaches to slowing the clock: one targets immune cells, the other a mineral in groundwater.
New Scientist revisits the 'Crazy Well' anecdote and the science behind low-dose lithium orotate for Alzheimer's prevention. Animal studies look promising, and a human trial is coming, but it's early days.
Everyday risks and systems
The rest of the day's news is about the small things that add up, hot drinks, toilet plumes, and the systems meant to help.
Oxford researchers found that drinking beverages at 65°C or higher may damage the esophagus and increase cancer risk. Six or more very hot drinks a day elevates that risk further. Adding milk helps a little.

A review of 22 studies confirms that flushing toilets create aerosol plumes containing pathogens like norovirus and influenza. Closing the lid isn't enough, the particles still reach your breathing zone.
As patients stop GLP-1 drugs, weight regain is hitting mental health hard. Physicians are being told to set realistic expectations early: the drugs are a tool, not a solution.
