Model: Young (2- to 4-month-old) and aged (9- to 10-month-old) C57Bl/6JR mice, APP/PS1 mice, and 5xFAD mice 
Dosage: 0.2 mg/mL of doxycycline in drinking water starting at least 7 days before surgery and ceased 2 days before the partial cellular reprogramming window for engram tagging, after which it was immediately reintroduced

Gene Therapy Restores Cognitive Function in Aging and Alzheimer’s Disease

Delivering a gene therapy targeting ensembles of neurons that store memories restores learning and memory capabilities in mouse models of aging and Alzheimer’s disease.

New Study Shows Cranberry Extract Equivalent to Metformin in Fighting Aging

Fayoum University researchers found that cranberry polyphenols improve metabolic markers, cognition, and oxidative stress to the same degree as the drug metformin.

A new study suggests cranberry extract has effects against aging that rival metformin.

The Rise of China’s Longevity Movement: A Quest to Defy Aging

China’s national project to crush aging encompasses longevity labs, “immortality islands,” and grapeseed pills, as well as exorbitant claims based on sometimes questionable science.

(Attendees at a conference in Shanghai try out a cryogenic chamber in which temperatures plummeted to approximately -200 degrees Fahrenheit, meant to slow aging | New York Times)

A surge in the Chinese public’s interest in longevity science has led to substantial investments from the state and private companies in aging research.

Model: Male ApoE−/− mice fed a high-fat diet for 12 weeks to induce atherosclerosis.
Dosage: Methyl-β-cyclodextrin (Mß-CD) at 2.0 g/kg, subcutaneous injection, twice a week

 A new study shows cyclodextrin reduces artery plaques in mice by lowering cholesterol and blocking inflammatory cell death.
