Ancient mind-body practice proven to lower blood pressure in clinical trial

A traditional Chinese mind-body practice that combines slow, structured movement, deep breathing and meditative focus lowered blood pressure as effectively as brisk walking in a large randomized clinical trial published in JACC. Blood pressure reductions were seen after three months and sustained for one year.

High blood pressure is one of the leading preventable risk factors for heart disease. Clinical guidelines recommend regular physical activity, yet long-term adherence to exercise programs is challenging for many people, particularly when routines require equipment, dedicated space, gym memberships or ongoing supervision.

Baduanjin is a widely practiced, standardized eight-movement sequence that integrates aerobic, isometric, flexibility and mind–body components. Practiced for centuries and commonly performed in community settings across China, the routine typically takes 10–15 minutes and requires no equipment and only minimal initial instruction, allowing it to be performed in a wide range of settings. Because it is low-to moderate-intensity, it is considered safe and accessible for many adults.

Identifying the Axillary Substructure at Risk for Lymphedema in Operable Patients With Breast Cancer Receiving Regional Nodal Irradiation

New in practicalRO.

Axillary substructures may contribute to the development of breast cancer-related lymphedema (BCRL). This study aimed to compare dose-volume parameters of various substructures to identify high-risk regions associated with BCRL and to evaluate the clinical applicability of these findings.

Mapping protein production in brain cells yields new insights for brain disease

The brain’s ability to do everything from forming memories to coordinating movement relies on its cells producing the right proteins at the right time. But directly measuring this protein production, known as translation, across different types of brain cells has been a challenge.

Now, scientists at University of California School of Medicine, Scripps Research and their colleagues have developed a technology that reveals which proteins are generated by individual brain cells. The team used their method—called Ribo-STAMP—to create the first maps of protein production across nearly 20,000 individual cells in the mouse hippocampus, a brain region essential for learning and memory.

The study was published in Nature.

Lipid droplet-induced T cell death sustains autoimmune tissue inflammation

Kumar et al. identify a metabolically controlled trait of CD4+ T cells in autoimmune disease. Exposed to fatty acids in rheumatoid joints, they form lipid droplets containing pore-forming gasdermin D and its activator zDHHC5. These droplets induce plasma membrane lysis, resulting in the leakage of intracellular contents and tissue inflammation.

Record-breaking photons at telecom wavelengths

A team of researchers from the University of Stuttgart and the Julius-Maximilians-Universität Würzburg led by Prof. Stefanie Barz (University of Stuttgart) has demonstrated a source of single photons that combines on-demand operation with record-high photon quality in the telecommunications C-band—a key step toward scalable photonic quantum computation and quantum communication. “The lack of a high-quality on-demand C-band photon source has been a major problem in quantum optics laboratories for over a decade—our new technology now removes this obstacle,” says Prof. Stefanie Barz.

The key: Identical photons on demand In everyday life, distinguishing features may often be desirable. Few want to be exactly like everyone else. When it comes to quantum technologies, however, complete indistinguishability is the name of the game. Quantum particles such as photons that are identical in all their properties can interfere with each other—much as in noise-canceling headphones, where sound waves that are precisely inverted copies of the incoming noise cancel out the background.

When identical photons are made to act in synchrony, then the probability that certain measurement outcomes occur can be either boosted or decreased. Such quantum effects give rise to powerful new phenomena that lie at the heart of emerging technologies such as quantum computing and quantum networking. For these technologies to become feasible, high-quality interference between photons is essential.

Gut-derived metabolite hippuric acid ‘turns up’ immune inflammation, study finds

Scientists at The Wistar Institute have identified a previously overlooked mediator in the body’s response to life-threatening infections: hippuric acid, a metabolite produced when gut bacteria break down polyphenols from berries, tea, and other plant-based foods. The research reveals that this molecule acts as an immune-system amplifier, boosting the body’s inflammatory defenses during early infection but elevating them to deadly levels when infections progress to sepsis.

Published in Cell Reports, the study demonstrates that elevated hippuric acid levels correlate with increased mortality in sepsis patients, while also uncovering the molecular mechanisms by which this metabolite modifies immune responses. The findings could lead to new approaches for managing severe infections and, potentially, for treating pancreatic cancer.

“Hippuric acid is a metabolite that has historically been seen as a benign byproduct of metabolism and is therefore understudied,” said Rahul S. Shinde, D.V.M., Ph.D., assistant professor in the Molecular and Cellular Oncogenesis Program at the Ellen and Ronald Caplan Cancer Center at The Wistar Institute and senior author of the study. “This paper identifies that it’s not just a passive byproduct. It has bioactive potential to influence the immune system.”

The Hume Band Might Be the Smartest Wearable for Stress + Recovery Yet

The Hume Band is quickly becoming one of the most interesting smart wearables in the longevity and performance space.

It tracks stress using HRV and other physiological signals distinguishing between productive stress (like training) and chronic stress (like anxiety). On top of that, it monitors the full suite of vitals: heart rate, SpO₂, respiratory rate, skin temperature, strain, and recovery.

The best part? It actually makes the data usable, instead of overwhelming.

BREAKTHROUGH: How Consciousness Creates the Simulation | Dr. Donald Hoffman

Cognitive Scientist, Dr. Donald Hoffman returns to the mind meld!
Are we, as Plato argued thousands of years ago, mistaking shadows on a cave wall for reality?

In this conversation with the brilliant Dr. Donald Hoffman, we question whether space-time and the world we experience with our senses is fundamental or merely a shallow projection of something deeper. Drawing on Plato’s cave, physics, cognitive science, mystical traditions, quantum theory, and Hoffman’s own framework of conscious agents, we explore the possibility that reality emerges from consciousness rather than the other way around. Don also shares what could be a mind blowing breakthrough in his theory.
What is reality? Will science ever find a final theory of everything? Are we locked inside a simulation designed for survival, not truth? If consciousness transcends space-time, what does that imply about our potential, our perception, our purpose and our fate as beings? We riff on all of this and more in this mind meld.

Chitosan-nickel biomaterial becomes stronger when wet, and could replace plastics

A new study led by the Institute for Bioengineering of Catalonia (IBEC) has unveiled the first biomaterial that is not only waterproof but actually becomes stronger in contact with water. The material is produced by the incorporation of nickel into the structure of chitosan, a chitinous polymer obtained from discarded shrimp shells. The development of this new biomaterial marks a departure from the plastic-age mindset of making materials that must isolate from their environment to perform well. Instead, it shows how sustainable materials can connect and leverage their environment, using their surrounding water to achieve mechanical performance that surpasses common plastics.

Plastics have become an integral part of modern society thanks to their durability and resistance to water. However, precisely these properties turn them into persistent disruptors of ecological cycles. As a result, unrecovered plastic is accumulating across ecosystems and becoming an increasingly ubiquitous component of global food chains, raising growing concerns about potential impacts on human health.

In an effort to address this challenge, the use of biomaterials as substitutes for conventional plastics has long been explored. However, their widespread adoption has been limited by a fundamental drawback: Most biological materials weaken when exposed to water. Traditionally, this vulnerability has forced engineers to rely on chemical modifications or protective coatings, thereby undermining the sustainability benefits of biomaterial-based solutions.
