Millionaire biohacker Bryan Johnson has shared his anti-aging lunch that can apparently help you live until the age of 120.
Johns Hopkins Medicine scientists who arranged for 48 human bioengineered heart tissue samples to spend 30 days at the International Space Station report evidence that the low gravity conditions in space weakened the tissues and disrupted their normal rhythmic beats when compared to Earth-bound samples from the same source.
The scientists said the heart tissues “really don’t fare well in space,” and over time, the tissues aboard the space station beat about half as strongly as tissues from the same source kept on Earth.
The findings, they say, expand scientists’ knowledge of low gravity’s potential effects on astronauts’ survival and health during long space missions, and they may serve as models for studying heart muscle aging and therapeutics on Earth.
Life expectancy growth has slowed since 1990, with average gains of only 6.5 years in the longest-living populations, suggesting a possible biological limit. A new study emphasizes shifting focus from merely extending life to improving the quality of life through advancements in aging science. Life expectancy saw dramatic increases throughout…
1 Timothy 6:16 is one of the foundational verses for conditionalists. In it, we see a theological principle that we are not ready to relinquish in favour of popular teachings. It is the principle that God is the only being in the universe who has immortality; only God has Immortality His immortality is exclusive. In that respect, he is different from all other beings.
“The only One who has immortality, dwelling in unapproachable light; no one has seen or can see Him, to Him be honour and eternal might. Amen” (HCSB).
The verse is the second part of a doxology: a pause to praise the God of whom the author is writing. In its context, Paul is encouraging Timothy to keep pursuing eternal life to which he was called, but has not yet attained. It is a promise from the only one capable of making that promise: God, who alone possesses that thing that Paul urges Timothy to pursue.
This is about life expectancy, not radical life extension.
A new study has suggested that radical life extension is all but impossible in this century [1], and it has made waves among people interested in living longer.
A paper titled “Implausibility of radical life extension in humans in the twenty-first century” was destined to ignite controversy in the longevity community. Published in Nature Aging, it lists Jay Olshansky as its corresponding author, a renowned researcher who has been studying the populational dynamics of life expectancy for decades. We delved deeper into this study and reached several prominent community members for comments.
Human Immortality — If you thought Human Immortality was just a concept in science fiction, this episode reveals how it will become science fact. For some scientists featured in this program, achieving Immortality is not a question of ‘If’. The real question is ‘When?’

Researchers are queuing up to try a powerful microscopy technique that can simultaneously sequence an individual cell’s DNA and pinpoint the location of its proteins with high resolution — all without having to crack the cell open and extract its contents. Imaging DNA and proteins inside intact cells provides crucial information about how these molecules work together.
The method’s developers have already used it to study how ageing might alter the way that proteins in the nucleus interact with chromosomes. As the body ages, they found, changes in these nuclear proteins could suppress gene activity.
“This paper is really extraordinary,” says Ankur Sharma, a cancer biologist at the Garvan Institute of Medical Research in Sydney, Australia, who was not involved in the study but is keen to use the approach to study cancer cells and described it as “phenomenal” on the social-media platform, X.
Summary: New research demonstrates that learning a second language enhances brain connectivity, particularly when started in childhood. Scientists found that bilingual individuals have more efficient communication between brain regions, notably between the cerebellum and left frontal cortex.
The study, which used whole-brain fMRI scans, shows this effect increases the younger a second language is learned, suggesting an early boost to cognitive flexibility and neuroplasticity. This heightened connectivity may improve cognitive performance and resilience to age-related decline. The findings contribute to understanding bilingualism’s broader impact on the brain and could have implications for education and brain health.
While caloric restriction (CR) has long been associated with increased lifespan, the study found that its effectiveness is highly influenced by individual genetic factors; some mice on restrictive diets experienced a notable lifespan extension, while others saw minimal gains.
New research on mice suggests that while extreme caloric restriction may extend lifespan, genetic resilience plays a critical role.
Improvements in public health and medicine have lengthened human survival, but science has yet to overcome ageing.
