Research shows how immune system reacts to pig kidney transplants in living patients

Novel research led by Brazilian scientists describes the immune system’s reactions in detail in the first living patient to receive a genetically modified pig kidney transplant. This paves the way for the search for therapies that can prevent organ rejection.

The study demonstrates the feasibility of this type of graft but indicates that controlling initial rejection alone is insufficient. This is because even with immunosuppressants, continuous activation of innate immunity—the body’s first line of defense, especially macrophages, which react to any threat—can compromise long-term survival.

Through transcriptomic, proteomic, metabolomic, and spatial analyses, the scientists have determined that new strategies are necessary to achieve long-term survival and favorable clinical outcomes. They recommend combining therapies that target innate immunity with advanced genetic engineering in donor pigs. They also suggest preventing early T lymphocyte-mediated rejection and implementing more sensitive monitoring approaches.

This CRISPR breakthrough turns genes on without cutting DNA

A new CRISPR breakthrough shows scientists can turn genes back on without cutting DNA, by removing chemical tags that act like molecular anchors. The work confirms these tags actively silence genes, settling a long-running scientific debate. This gentler form of gene editing could offer a safer way to treat Sickle Cell disease by reactivating a fetal blood gene. Researchers say it opens the door to powerful therapies with fewer unintended side effects.

Worm-Inspired Active Filaments Sweep Disorder into Order

The ability of single active filaments to cluster smaller particles could inspire new materials for building soft robots that perform biological functions.

Every teenager knows that their room will not tidy up by itself. Without intervention, it will inevitably become messier, and they will need to do some work to turn disorder into order. When faced with a similar problem—particle collection—scientists have tried to get individual bacteria, robots, or other self-propelling units to put in the work [1, 2]. But unlike a teenager, a single such unit is usually insufficient to get the job done. Now Rosa Sinaasappel of the University of Amsterdam and her collaborators have proposed and tested a strategy that enables a single active filament to act as a sweeping agent [3]. Thanks to the versatility of polymer architectures, the investigation opens up a huge molecular-design space.

One of life’s most defining properties is its constant struggle against the second law of thermodynamics. At different scales, living organisms need to maintain complex structures or perform directed and persistent motion, feats that would be extraordinarily improbable in thermal equilibrium [4]. Organisms are able to sustain order against entropy by means of constant energy consumption, a feature called “activity.” Conceptually, the sweeping of small objects into piles is a similar problem. The goal is to reach a low-entropy state that is highly disfavored at equilibrium. Bacteria and other active particles, driven by their persistent motion, spontaneously aggregate, and they have been shown to induce clustering of passive particles [1, 2]. However, successful clustering typically requires using a large number of active particles or engineering a complex setting with a favorable geometry [5, 6].

Who Wants to Enhance Their Cognitive Abilities? Potential Predictors of the Acceptance of Cognitive Enhancement

In the 21st century, new powerful technologies, such as different artificial intelligence (AI) agents, have become omnipresent and the center of public debate. With the increasing fear of AI agents replacing humans, there are discussions about whether individuals should strive to enhance themselves. For instance, the philosophical movement Transhumanism proposes the broad enhancement of human characteristics such as cognitive abilities, personality, and moral values (e.g., ; ). This enhancement should help humans to overcome their natural limitations and to keep up with powerful technologies that are increasingly present in today’s world (see ). In the present article, we focus on one of the most frequently discussed forms of enhancement—the enhancement of human cognitive abilities.

Not only in science but also among the general population, cognitive enhancement, such as increasing one’s intelligence or working memory capacity, has been a frequently debated topic for many years (see ). Thus, a lot of psychological and neuroscientific research investigated different methods to increase cognitive abilities, but—so far—effective methods for cognitive enhancement are lacking (). Nevertheless, multiple different (and partly new) technologies that promise an enhancement of cognition are available to the general public. Transhumanists especially promote the application of brain stimulation techniques, smart drugs, or gene editing for cognitive enhancement (e.g., ). Importantly, only little is known about the characteristics of individuals who would use such enhancement methods to improve their cognition. Thus, in the present study, we investigated different predictors of the acceptance of multiple widely-discussed enhancement methods. More specifically, we tested whether individuals’ psychometrically measured intelligence, self-estimated intelligence, implicit theories about intelligence, personality (Big Five and Dark Triad traits), and specific interests (science-fiction hobbyism) as well as values (purity norms) predict their acceptance of cognitive enhancement (i.e., whether they would use such methods to enhance their cognition).

New image sensor breaks optical limits

Imaging technology has transformed how we observe the universe—from mapping distant galaxies with radio telescope arrays to unlocking microscopic details inside living cells. Yet despite decades of innovation, a fundamental barrier has persisted: capturing high-resolution, wide-field images at optical wavelengths without cumbersome lenses or strict alignment constraints.

A new study by Guoan Zheng, a biomedical engineering professor and the director of the UConn Center for Biomedical and Bioengineering Innovation (CBBI), and his research team at the UConn College of Engineering, was published in Nature Communications, introducing a breakthrough solution that could redefine optical imaging across science, medicine, and industry.

“At the heart of this breakthrough is a longstanding technical problem,” said Zheng. “Synthetic aperture imaging—the method that allowed the Event Horizon Telescope to image a black hole—works by coherently combining measurements from multiple separated sensors to simulate a much larger imaging aperture.”

Heart-brain connection: International study reveals role of vagus nerve in keeping the heart young

The secret to a healthier and “younger” heart lies in the vagus nerve. A recent study coordinated by the Sant’Anna School of Advanced Studies in Pisa and published in Science Translational Medicine has shown that preserving bilateral cardiac vagal innervation is an anti-aging factor. In particular, the right cardiac vagus nerve emerges as a true guardian of cardiomyocyte health, helping to preserve the longevity of the heart independently of heart rate.

The study is characterized by a strongly multidisciplinary approach, integrating experimental medicine and bioengineering applied to cardiovascular research. Specifically, the research was led by the Translational Critical Care Unit (TrancriLab) of the Interdisciplinary Research Center Health Science, under the responsibility of Professor Vincenzo Lionetti, and by the laboratory of the Biorobotics Institute led by Professor Silvestro Micera, which contributed to the development of the bioabsorbable nerve conduit used to facilitate vagal regeneration.

The study involved a broad network of Italian and international institutions of excellence, including the Scuola Normale Superiore, the University of Pisa, the Fondazione Toscana G. Monasterio, the Institute of Clinical Physiology of the CNR, the University of Udine, GVM Care & Research, Al-Farabi Kazakh National University, the Leibniz Institute on Ageing in Jena and the École Polytechnique Fédérale de Lausanne.

Longevity in 2025: The Breakthroughs That Actually Mattered

This year quietly rewired how researchers think about aging, what truly predicts long-term health, and which biohacking ideas deserve serious attention versus skepticism. From brain aging to muscle strength, from AI-driven drug discovery to cooling hype around supplements, 2025 redrew the map of healthspan science.

Here’s the clear-eyed recap of what actually mattered.

Reining In a Chaotic Fluid

Fluid flows mimicking biological flows can be controlled in the lab using a feedback system, which could be useful in robotics and other technologies.

Ordinary fluids can flow when driven by pressure or gravity, but biological fluids, such as those inside cells, generate complex flows through internal sources of chemical energy. Flows of such “active fluids” could be extremely useful in robotics and other areas of engineering, but controlling them remains difficult. Now researchers have demonstrated a method of control that maintains a constant fluid speed despite changing conditions [1]. They hope that the approach can be used to stabilize active-matter flows in future technologies.

Life depends on biochemical processes that respond to many situations while maintaining fixed chemical conditions despite external and internal disruptions. Inspired by this impressive stability, researchers have been developing analogous artificial systems by assembling active fluids from key biochemical components akin to those inside cells. For example, they have created fluids that can generate their own bulk contractions or undergo spontaneous flows. Although these rudimentary designs mimic some features of living matter, researchers have so far failed to demonstrate techniques that keep properties such as fluid flow speeds stable over time.
