How to Turn Genes On or Off to Protect Brain Cells From Dementia

—

What they discovered.

Kampmann’s work, supported by the National Institutes of Science (NIH), maps cellular “decision points” that determine whether brain cells survive or die — laying the groundwork for treatments that intervene before irreversible brain damage occurs.

Using CRISPR-based gene targeting technology that his team helped develop and pioneer the use of in brain cells, Kampmann has identified genes and cellular processes that influence the buildup of amyloid plaque and tau in the brain, two primary contributors to dementia. Thanks to this technology, called CRISPR interference and CRISPR activation, select genes in the laboratory can be turned on or off to protect brain cells from decline.

“We can conduct large-scale experiments that target all the genes in the human genome — 20,000 of them,” said Kampmann, explaining his work after receiving the Byers Award earlier this year. “And that way, we can basically have a little knob on each gene to ask which of all of the genes play a role in a disease.”

Active Matter Gets Solid

Coaxing tiny, self-propelled particles into cohesive structures suggests an approach for making micromachines inspired by living systems. Taking a step toward that goal, researchers have poked and prodded strands of material made from such “active” particles and measured their responses [1]. Understanding the mechanics of structures like these will be essential for the design of devices such as cilia sheets or autonomous microrobots that perform tasks in materials assembly or medicine.

Active matter refers to collections of objects that can move on their own via some energy-consuming process. For 15 years, researchers have studied active fluids that, for example, model the emergent behaviors typical of flocking birds or schooling fish. More recently, researchers have begun to explore active solids—semirigid structures made from active particles. These structures could, in principle, change their shapes in controlled ways or adapt their locomotion to suit their surroundings.

Jérémie Palacci of the Institute of Science and Technology Austria and his colleagues previously designed an active solid made from 2-µm-diameter particles submerged in water [2]. Each particle is a plastic sphere with a hematite cube fixed to its surface. When exposed to blue light, the hematite reacts with hydrogen peroxide in the water and emits the reaction products, a bit like an underwater jet.

Muscle tissue from a 3D printer—produced in zero gravity

Human health is the Achilles heel of space travel. Researchers at ETH Zurich have now succeeded in printing complex muscle tissue in zero gravity. This will enable drugs for space missions to be tested in the future.

On their way into space, astronauts’ bodies deteriorate dramatically in . To address this problem and protect our pioneers in space, researchers are looking for realistic test models.

This is precisely where the research of a team at ETH Zurich comes in. To produce under the most precise conditions possible, the research team led by Parth Chansoria used parabolic flights to simulate the microgravity of space for a short period of time. This technical feat brings the researchers closer to their long-term goal: growing human tissue in orbit to study diseases and develop new therapies.

Imaging study shows how brains go off-track in rare childhood disorder

Researchers at the VIB-UAntwerp Center for Molecular Neurology have visualized how brain network development is altered in a model of KCNQ2-related developmental and epileptic encephalopathy, a rare childhood brain disorder. Using longitudinal imaging techniques, the team observed differences in how brain regions communicate and connect, long before behavioral symptoms appear.

KCNQ2-related developmental and epileptic encephalopathy (KCNQ2-DEE) is a rare but severe neurological disorder that affects newborns. Children with this condition typically develop seizures within days after birth and continue to face learning and movement difficulties. The disorder is caused by mutations in a potassium-channel gene that disrupts normal brain activity.

To investigate how this disorder affects , the team of Professor Sarah Weckhuysen visualized and structure throughout early growth in mice carrying the same genetic defect. The study is published in the journal eBioMedicine.

Scientists Unlock the Cancer-Fighting Power of the Rarest Element on Earth

Texas A&M researchers have unlocked a new way to harness astatine-211, a rare and powerful isotope that may revolutionize cancer treatment. Astatine is the rarest naturally occurring element on the planet and among the least explored in the periodic table, largely because its name, derived fr

First Stem Cell Transplant from Deceased Donor Multiple Myeloma

A 68-year-old woman with relapsed acute myeloid leukemia (AML) underwent what appears to be the first successful stem cell transplant using stem cells recovered from a deceased donor. The procedure was performed at Henry Ford Health in Detroit and is notable because it may expand access for people who cannot find a suitable living donor, a barrier that mainly affects people from racial and ethnic minorities.

First-in-world marrow transplant from a deceased donor and what trials mean for access and timelines.

Benchmarking large language models for personalized, biomarker-based health intervention recommendations

The use of large language models (LLMs) in clinical diagnostics and intervention planning is expanding, yet their utility for personalized recommendations for longevity interventions remains opaque. We extended the BioChatter framework to benchmark LLMs’ ability to generate personalized longevity intervention recommendations based on biomarker profiles while adhering to key medical validation requirements. Using 25 individual profiles across three different age groups, we generated 1,000 diverse test cases covering interventions such as caloric restriction, fasting and supplements. Evaluating 56,000 model responses via an LLM-as-a-Judge system with clinician validated ground truths, we found that proprietary models outperformed open-source models especially in comprehensiveness. However, even with Retrieval-Augmented Generation (RAG), all models exhibited limitations in addressing key medical validation requirements, prompt stability, and handling age-related biases. Our findings highlight limited suitability of LLMs for unsupervised longevity intervention recommendations. Our open-source framework offers a foundation for advancing AI benchmarking in various medical contexts.

Homo Invocator

We live immersed in a persistent illusion: the idea that consciousness arises from the brain like the flame from a candle. Contemporary science, constrained by the very instruments it creates, proclaims that the mind is merely the result of electrical impulses and chemical reactions — an epiphenomenon of flesh.

Yet a deeper look — one that doesn’t reject science but rather transcends it — reveals a more radical reality: we, living beings, are not the origin of consciousness, but rather its antenna.

We are hardware. Bodies shaped by millions of years of biological evolution, a complex architecture of atoms and molecules organized into a fractal of systems. But this hardware, no matter how sophisticated, is nothing more than a receptacle, a stage, an antenna. What truly moves, creates, and inspires does not reside here, within this tangible three-dimensional realm; it resides in an unlimited field, a divine matrix where everything already exists. Our mind, far from being an original creator, is a channel, a receiver, an interpreter.

The great question of our time — and perhaps of all human history — is this: how can we update the software running on this biological hardware without the hardware itself becoming obsolete? Herein lies the fundamental paradox: we can dream of enlightenment, wisdom, and transcendence, yet if the body does not keep pace — if the physical circuits cannot support the flow — the connection breaks, the signal distorts, and the promise of spiritual evolution stalls.

The human body, a product of Darwinian evolution’s slow dance, is both marvel and prison. Our eyes capture only a minuscule fraction of the electromagnetic spectrum; our ears are limited to a narrow range of frequencies; our brains filter out and discard 99% of the information surrounding us. Human hardware was optimized for survival — not for truth!

This is the first major limitation: if we are receivers of a greater reality, our apparatus is radically constrained. It’s like trying to capture a cosmic symphony with an old radio that only picks up static. We may glimpse flashes — a sudden intuition, an epiphany, a mystical experience — but the signal is almost always imperfect.

Thus, every spiritual tradition in human history — from shamans to mystery schools, from Buddhism to Christian mysticism — has sought ways to expand or “hack” this hardware: fasting, meditation, chanting, ecstatic dance, entheogens. These are, in fact, attempts to temporarily reconfigure the biological antenna to tune into higher frequencies. Yet we remain limited: the body deteriorates, falls ill, ages, and dies.

If the body is hardware, then the mind — or rather, the set of informational patterns running through it — is software: human software (and a limited one at that). This software isn’t born with us; it’s installed through culture, language, education, and experience. We grow up running inherited programs, archaic operating systems that dictate beliefs, prejudices, and identities.

Beneath this cultural software, however, lies a deeper code: access to an unlimited field of possibilities. This field — call it God, Source, Cosmic Consciousness, the Akashic Records, it doesn’t matter — contains everything: all ideas, all equations, all music, all works of art, all solutions to problems not yet conceived. We don’t invent anything; we merely download it.

Great geniuses throughout history — from Nikola Tesla to Mozart, from Leonardo da Vinci to Fernando Pessoa — have testified to this mystery: ideas “came” from outside, as if whispered by an external intelligence. Human software, then, is the interface between biological hardware and this divine ocean. But here lies the crucial question: what good is access to supreme software if the hardware lacks the capacity to run it?

An old computer might receive the latest operating system, but only if its minimum specifications allow it. Otherwise, it crashes, overheats, or freezes. The same happens to us: we may aspire to elevated states of consciousness, but without a prepared body, the system fails. That’s why so many mystical experiences lead to madness or physical collapse.

Thus, we arrive at the heart of the paradox. If the hardware doesn’t evolve, even the most advanced software download is useless. But if the software isn’t updated, the hardware remains a purposeless machine — a biological robot succumbing to entropy.

Contemporary society reflects this tension. On one hand, biotechnology, nanotechnology, and regenerative medicine promise to expand our hardware: stronger, more resilient, longer-lived bodies. On the other, the cultural software governing us remains archaic: nationalism, tribalism, dogma, consumerism. It’s like installing a spacecraft engine onto an ox-drawn cart.

At the opposite end of the spectrum, we find the spiritual movement, which insists on updating the software — through meditation, energy therapies, expanded states of consciousness — but often neglects the hardware. Weakened, neglected bodies, fed with toxins, become incapable of sustaining the frequency they aim to channel. The result is a fragile, disembodied spirituality — out of sync with matter.

Humanity’s challenge in the 21st century and beyond is not to choose between hardware and software, but to unify them. Living longer is meaningless if the mind remains trapped in limiting programs. Aspiring to enlightenment is futile if the body collapses under the intensity of that light.

It’s essential to emphasize: the power does not reside in us (though, truthfully, it does — if we so choose). This isn’t a doctrine of self-deification, but of radical humility. We are merely antennas. True power lies beyond the physical reality we know, in a plane where everything already exists — a divine, unlimited power from which Life itself emerges.

Our role is simple yet grand: to invoke. We don’t create from nothing; we reveal what already is. We don’t invent; we translate. A work of art, a mathematical formula, an act of compassion — all are downloads from a greater source.

Herein lies the beauty: this field is democratic. It belongs to no religion, no elite, no dogma. It’s available to everyone, always, at any moment. The only difference lies in the hardware’s capacity to receive it and the (human) software that interprets it.

But there are dangers. If the hardware is weak or the software corrupted, the divine signal arrives distorted. This is what we see in false prophets, tyrants, and fanatics: they receive fragments of the field, but their mental filters — laden with fear, ego, and the desire for power — twist the message. Instead of compassion, violence emerges; instead of unity, division; instead of wisdom, dogma.

Therefore, conscious evolution demands both purification of the software (clearing toxic beliefs and hate-based programming) and strengthening of the hardware (healthy bodies, resilient nervous systems). Only then can the divine frequency manifest clearly.

If we embrace this vision, humanity’s future will be neither purely biological nor purely spiritual — it will be the fusion of both. The humans of the future won’t merely be smarter or longer-lived; they’ll be more attuned. A Homo Invocator: the one who consciously invokes the divine field and translates it into matter, culture, science, and art.

The initial paradox remains: hardware without software is useless; software without hardware is impossible. But the resolution isn’t in choosing one over the other — it’s in integration. The future belongs to those who understand that we are antennas of a greater power, receivers of an infinite Source, and who accept the task of refining both body and mind to become pure channels of that reality.

If we succeed, perhaps one day we’ll look back and realize that humanity’s destiny was never to conquer Earth or colonize Mars — but to become a conscious vehicle for the divine within the physical world.

And on that day, we’ll understand that we are neither merely hardware nor merely software. We are the bridge.

Deep down, aren’t we just drifting objects after all?
The question is rhetorical, for I don’t believe any of us humans holds the answer.

Gum disease associated with changes in the brain, increased stroke risk

Adults with gum disease may be more likely to have signs of damage to the brain’s white matter, called white matter hyperintensities, than people without gum disease, according to a study published in Neurology Open Access.

White matter refers to nerve fibers that help different parts of the brain communicate. Damage to this tissue can affect memory, thinking, balance and coordination and has been linked to higher stroke risk.

White matter hyperintensities are bright spots that appear on brain scans that are thought to reflect damaged white matter tissue. While the study found an association, it does not prove that gum disease causes white matter damage.
