Researchers take major step toward cuff-free blood pressure monitoring

Researchers have shown, for the first time, that speckle contrast optical spectroscopy (SCOS) can be used for cuffless blood pressure monitoring. The new technology could improve early detection and management of hypertension.

“Hypertension affects nearly half of all adults in the US and is the leading cause of cardiovascular disease,” said Ariane Garrett, a doctoral student in Darren Roblyer’s lab at Boston University. “This research is a step toward a that would let people monitor their any time, without a cuff.”

SCOS is a noninvasive imaging technique that measures by analyzing speckle patterns formed by coherent light scattering from cells and tissue. While it has been used for other applications such as brain and tissue monitoring, this is one of the first studies to explore how SCOS signals relate to blood pressure.

Open House

Have you heard about the crazy guys who bought an entire tower to convert it into a vertical village? Yes, that’s us.

Do you want to walk the 16-floor tower and explore the space? Still on the fence, if you should become a citizen? Do you have questions about how you can get involved and co-create? Wanna hear updates on what happened in the last 2 weeks? This event is for you! 👩‍🚀

About us: We are transforming a 16-floor tower in the heart of San Francisco into a self-governed vertical village —a hub for frontier technologies and creative arts. 8 themed floors will be dedicated to creating tier-one labs, spanning AI, Ethereum, biotech, neuroscience, longevity, robotics, human flourishing, and arts & music. These floors will house innovators and creators pushing the boundaries of human potential in a post-AI-singularity world.

DNA as a perfect quantum computer based on the quantum physics principles

I believe that dna will be able to answer just about all our genetic coding questions so much that it will lead to even better breakthroughs in the future and use hardly any energy. I believe also that the master algorithm can eventually be derived from DNA as dna seems already a perfect master algorithm for human beings where human beings are the key to all future progress. I say this as quantum computing is still not stable but we already know that dna computers seem already a masterpiece already especially even organoids of the human brain. Really it becomes really quite simple as even the quantum realm is unstable but dna computers that are quantum would stabilize this currently unstable realm.

Mimicking the benefits of exercise with a single molecule

Capital Medical University, in collaboration with the Chinese Academy of Sciences, reports that betaine, a molecule produced in the kidney and enhanced through sustained exercise, operates as a potent inhibitor of inflammatory and aging-related pathways.

Regular physical activity boosts health across cardiovascular, metabolic, and neurological systems. Scientists have traced improvements in , , clearing of senescent cells and to consistent physical activity. Earlier animal studies suggested that long-term exercise can delay aging processes and reduce vulnerability to chronic disease.

Precise molecular explanations for how sustained exercise reshapes human biology remain incomplete. Many investigations have focused on single biomarkers or isolated tissues, leaving a need for systematic maps that can connect exercise to measurable physiological benefits. Specific factors capable of mimicking exercise’s protective effects without requiring continuous physical exertion have remained unclear.
