GLP-1 medicines work through biological signalling between the gut, pancreas, brain and stomach. Here is what they amplify, what they change, and what they do not replace.
Living medicines use engineered cells, bacteria and other biological systems to sense, respond and deliver treatment. The promise is extraordinary — and so are the engineering challenges.
Bioelectronic medicine treats nerves as communication pathways that can sometimes be modulated electrically. Vagus nerve stimulation is one window into a fast-growing field.
When fresh water and salt water mix, a concentration difference disappears. That difference contains usable free energy. "Blue energy" technologies try to capture part of it before the waters fully mix.
Methylene blue is not a new "biohacking dye." It is a pharmacologically active compound with established medical uses, a long scientific history and potentially serious interactions. That makes it interesting — and exactly the wrong substance to treat casually.
A compound found in pomegranates does not simply "become urolithin A" in everyone. Gut microbes transform ellagitannins into metabolites, and only some people produce meaningful amounts. That makes urolithin A a fascinating story about food, microbes and mitochondrial research.
