Entrepreneur and founder of Blueprint. Publishes a detailed, freely available longevity protocol documenting the food, supplements, devices and measurements he uses on himself.
Old female mice on semaglutide lived 12% longer and ran 2.8× as long before exhaustion. Other gains: > treadmill time to exhaustion +177% > hanging time +124% > rotating-rod performance +47% > open-field movement +50% > glucose tolerance: area under the curve −20% > Improved spatial memory: maze escape time −57% > reduced inflammation -55% > reduced senescence -65% > stem cell rejuvenation: hippocampal neurons ~3x > bone marrow colonies +44% > DNA damage & stress -44% Treatment started at 20 months of age (human equivalent to 60s). Control was a separate group of mice on a 24% food restrictio… Related

Professor of Cognitive and Computational Neuroscience at the University of Sussex, co-director of the Sussex Centre for Consciousness Science, and author of Being You: A New Science of Consciousness.
An extraordinary @Nature paper has just landed from the lab of @Sergiu_P_Pasca at @Stanford - led by Konstantin Kaganovsky. They have found a way to create "xenocortical mice" which have ~92% of their cortex occupied by a cortical organoid derived from human stem cells. This human-derived cortical graft integrates deeply with the host nervous system, supporting organised neural activity and behaviour. This study is a milestone in synthetic biology and chimera research. It has the potential to generate multiple medical breakthroughs by providing an enhanced biological model of human brain tiss… nature.com

I find myself in a situation of creating favicons for a few things (it’s an internal task) and so I need to make ones that work in dark mode as well as light. I know how to make adaptive favicons, but does anyone have pointers to good *visual* best practices for dark mode favicons? My DuckDuck-fu is only turning up how to make them adaptive, not what they should actually look like to read well against a dark tab background. Related

What is a korrent?
A korrent is a belief a person has stated in their own words: one
sentence stating the claim, backed by a quote and a source, kept at
korrents.com .
Under a name here, the quoted block is what they actually said.
The korrent beneath it is the claim those words support, in
korrents' wording — tap it to see the record, its source, and who
else holds it.
Nobody here wrote their own korrents. They are compiled from public
statements, and a person can change their mind, which is recorded too.

About the English under a post
Some people here publish in a language other than English. Where they
do, this site shows a machine translation beneath the post, in
this typeface — the site's own, not theirs.
The post itself is never changed, moved or hidden: what is set in the
serif above is exactly what the person published, and it is what to
quote them on. A translation can be wrong in ways that matter,
especially about tone.
Only the post's own words are translated. A quoted post, a linked
article and a belief on korrents.com
are left in their original language.
