Longevity Interventions
Яцек Хоффман proposes selecting combinations of anti-aging interventions based on the current state of the organism. On August 19, Яцек Хоффман published an essay with his author's hypothesis: to maintain health throughout a long life, it is necessary to evaluate several processes at once and select their combination based on the state of the organism. The starting point for Хоффман was a study on the heart of the Greenland shark. The authors studied the tissues of ten sharks aged approximately 100-155 years and found fibrosis, lipofuscin, and signs of oxidative stress.
Before capture, the animals were found, chased, and caught with bait; the authors consider this indirect evidence of preserved physiological function. Хоффман takes the discrepancy between tissue damage and active behavior of the sharks as a reason to question this in humans. In his hypothesis, the organism must maintain several processes at once, and enhancing one changes the conditions for the others.
Active removal of damaged cells helps to restrain tumors, but increases the tissue's need for restoration. Stem cells replenish lost cells; the more they divide, the more the tissue is renewed and the more opportunities there are for changes in individual cells. The immune system recognizes infections and anomalous cells, and its prolonged activation damages tissues. One intervention changes the work of other systems.
Therefore, Хоффман proposes choosing an intervention based on age, specific tissue, accumulated damage, and resource reserve. His sequence of actions looks like this: "Observation → reconstruction of the current state → causal model → selection of intervention → action → repeated measurement → model update". Хоффман proposes testing this hypothesis by comparing models, such as those described in Nature Aging, July 2026.

Tomorrow Bio Report
Tomorrow.bio released a video and table on August 18 about five cryonics providers, comparing their legal structure, standby procedures, storage, and patient care funding. A cryonics contract links the first hours after official death declaration with decades-long storage.
In a breakdown by Max More, cryocenters were evaluated based on their performance in the first hours and their ability to store patients for decades. Before placement in liquid nitrogen, a standby team stabilizes the patient, administers cryoprotectants, and arranges transportation. Then, someone must maintain the storage facility and manage the patient care funds.
Tomorrow.bio released a video about the five providers on August 18 and published a table on its website with their legal forms, storage, standby procedures, and financing. The table was compiled by Tomorrow.bio itself, one of the comparison participants; in the video, the company asks for error reports in the data. Tomorrow.bio distributes its functions among three organizations: it keeps medical teams on standby, performs the procedure, and handles contracts.
The European Biostasis Foundation, a separate Swiss non-profit foundation, owns the storage facility and is responsible for the care within it. Co-founder Emil Kendziorra associates this scheme with different terms of work: the storage facility needs decades-long stability, while the operational company must change technologies and procedures. A contract with a provider can be read through four specific questions: who will attend to the patient, where they will be stored, who manages the patient care funds, and what happens if one of the organizations ceases to operate.

Gene Expression Boost
Researchers from Roche published a pre-review article on bioRxiv on August 16, exploring how different variants of a gene's recording, suggested by language models, can give a stronger signal. The language models proposed various variants of a gene's recording without changing the protein, and the authors then checked which ones gave a stronger signal in cells.
The codon, a triplet of letters in the genetic record, determines one amino acid of a protein. Most amino acids can be determined by several codons. The protein remains the same after such a replacement, but the RNA can fold differently, be more or less stable in the cell, or be read differently by the ribosome, the molecular machine that assembles the protein.
The authors compared three types of language models, one in two modes, with common programs that choose codons based on their frequency in the organism's genes. They created 68 variants of the SEAP gene, which codes for an enzyme whose activity is easy to measure in the medium around cells. The new preprint transfers this task to human cells and compares a library of variants from several models with randomly rewritten sequences.

Human Brain Organoids
The team of Paola Arlotta published a study in Nature on August 19, detailing the five-year growth of human cortical organoids, which are three-dimensional models of the cortex derived from stem cells. At 16 time points, the cells in these models underwent consecutive changes in maturation programs similar to those of the human cortex. Human cortex development takes years, while typical organoid experiments often end after months, with the previous longest culture lasting 694 days.
Arlotta's team grew organoids for five years to test whether the cells would continue to progress through the maturation program. The series consisted of 110 organoids and 424,720 individual cells. Researchers compared gene expression with human cortex data: from nine months to five years, the organoid cells increasingly resembled late prenatal and early postnatal development. DNA methylation, which affects gene expression, provided an independent scale: two out of three methylation clocks showed increasing tissue age as the culture period increased.
The most direct test was conducted in mixed organoids, where researchers combined precursor cells from 9-12 month organoids with cells from 15-day organoids. After 15 days, the younger portion gave rise to early types of cortex cells, while the older portion gave rise to later nerve and support cells, even though both grew in the same environment. Young cells partially shifted the programs of old precursors to earlier types, but later cell fates were preserved. In the shared environment, cells still carried the legacy of their already passed developmental stage.
To maintain exciting neurons that transmit signals to other cells in long-term culture, from the 70th day onwards, part of the organoids were grown in a medium that supported their spontaneous electrical activity. After a year, all nine such organoids exhibited network bursts; in eight control organoids, there were no bursts. In this medium, active networks were preserved for at least two years. After five years of observation, Arlotta identified the next challenge: "Now we need to understand how to make this process faster," she said.

Supercentenarians' Immune Cells
Researchers compared T-cells in the blood of 28 elderly individuals and found that people over 110 years old had a higher proportion of CD4 CTL, a type of T-cell that can attack infected and dangerously altered cells. The same team had previously found CD4 CTL in 7 supercentenarians in 2019. In their latest study, published on August 19, they investigated how this population changes with age by comparing 8 people aged 70-99, 10 centenarians, and 10 people over 110 years old.
The median proportion of CD4 CTL among all T-cells in these groups was 4.0%, 9.6%, and 17.6%, respectively. Typically, CD4 cells coordinate the immune response, but some of them can activate a cytotoxic program, producing proteins that T-cells use to destroy infected or altered cells. To understand the pathway of this transition, the team analyzed the active genes, surface proteins, and T-cell receptor sequence in each cell. Cells with the same receptor form a clone, meaning they originate from a single initial cell.
The authors discovered an intermediate stage between regular CD4 cells and CD4 CTL: the cell first loses the surface marker CD27 while retaining CD28, and then fully activates the attack program. The arrangement of these cells between the two groups, flow cytometry, and RNA analysis indicate this sequence of states. The largest clone in each participant had its own receptor sequence and occupied approximately one-third of all their CD4 CTL. The authors compared a short fragment of these receptors to a large database of sequences and found that 32 out of 36 matches for expanded clones were found in cancer patient samples, as reported in Nature Aging, July 2026.

Genetic Embryo Selection
Эрик Тополь questioned the accuracy of predicting IQ and height in embryo selection based on genetic scores. On August 16, cardiologist Эрик Тополь wrote about companies offering embryo selection services for up to $50,000, claiming to accurately predict IQ, height, and other traits.
In his post, Тополь expressed doubts about such claims, citing that polygenic scoring sums multiple DNA variants into a single genetic score. This score can capture statistical differences in a large group of people, but its application in embryo selection is limited, as it is applied to a few genetically similar embryos.
A 2019 study found that the average gain from selecting an embryo with the highest score was around 2.5 cm in height or 2.5 IQ points. The study used a combination of calculated models, simulations, and data from large families with grown children. As noted by Тополь, "You can't predict their IQ, height, and other traits with polygenic risk scores."
The American Society for Reproductive Medicine stated in its 2026 position that polygenic testing for traits like height, intelligence, and eye color is beyond the scope of reproductive medicine, citing it as an emerging and unproven technology.

Bacterial Enzyme Boosts Energy
The LplA enzyme from Escherichia coli was introduced into the mitochondria of worms and male mice. In 20-month-old mice, energy expenditure increased, and functional tests showed improved results in rotarod performance, grip strength, and glucose tolerance.
The LplA enzyme attaches lipoic acid to proteins, a chemical marker necessary for three enzyme complexes in mitochondria. To enable the enzyme to work near these targets, the authors added a mitochondrial delivery signal to it. Previous research found that mitochondrial lipoic acid attachment decreases with age in brown fat tissue of old mice, along with reduced fuel oxidation.
The new study checks if changes in this chemical marker translate to whole-organism functions. First, the authors traced the effects of LplA in worms, where it increased lipoic acid attachment, complex activity, mitochondrial respiration, and carbon flux from labeled glucose. Then, they used RNAi to temporarily suppress the genes of the three targets, one at a time, and found that LplA no longer increased respiration and mitochondrial membrane potential.
When LplA was introduced into adult worms on day 6 of life, by day 11, they moved faster and withstood heat and oxidative stress better, although lifespan did not change. Male mice were given an adenovirus carrying the genetic instructions for LplA at 4, 10, or 18 months and examined two months later, as reported in Science Advances, August 19.

Palbociclib Reduces Inflammation
The drug palbociclib weakened inflammation in aging cells and improved physical performance in old mice. Cyclin D1 typically helps a cell begin division, but the authors found its accumulation in cells that had already stopped dividing. In their model, cyclin D1, along with CDK6, maintained DNA damage and activated inflammatory genes.
On August 20, the journal Nature Aging published an article on the unexpected role of cyclin D1 in senescent cells. Senescence is a stable state after stress, such as DNA damage, where a cell stops dividing, remains in tissue, and can release signaling molecules that support inflammation. In July, abemaciclib was also found to weaken the inflammatory secretions of senescent cells in old mice.
The authors of the new study investigated a different pathway - the role of cyclin D1 and CDK6 in cells that had already stopped dividing. They found that reducing cyclin D1 or CDK6 levels weakened the activity of inflammatory and interferon genes, while intervening in CDK4 had little effect. The researchers then checked the mechanism, finding that the CCND1-CDK6 complex supported DNA damage.

Jokasta Neurosciences Deal
Jokasta Neurosciences received a direct license from the University of California, San Francisco (UCSF) for developments with the α-Klotho protein on August 19. The company reported an exclusive license, replacing and expanding previous rights obtained through Unity Biotechnology; the protein candidate JN-0413 remains in the preclinical stage, with the first phase planned to begin in early 2027. The new agreement gives Jokasta exclusive rights to UCSF's intellectual property related to α-Klotho, a protein whose levels decrease with age.
The license covers therapy for neurodegenerative diseases and the application of α-Klotho for cognitive and motor function. In May 2019, UCSF granted Unity Biotechnology an exclusive license for certain α-Klotho patents and know-how. In a 2021 agreement, Unity Biotechnology transferred sub-license rights to Jokasta - a license issued based on its contract with UCSF. Jokasta committed to paying an advance, future milestone payments, royalties - sales proceeds - and fulfilling payment obligations to UCSF under Unity's contract.
On September 26, 2025, Unity Biotechnology was legally dissolved. After the current deal, Jokasta reported that there are no future milestone payments and royalties under the old agreement with Unity. The choice of α-Klotho is based on published preclinical data, as described in a Nature Aging, July 2026 article, which is not directly referenced here but the research is mentioned.

Network Bio Funding
Network Bio has secured $50 million in funding and is collaborating with NVIDIA to develop a model based on RNA from blood samples. The company aims to train its Nexus model on tissue, blood, and health outcome data to identify patterns associated with disease development.
The Nexus model will analyze RNA profiles to identify repeating combinations linked to disease progression. To train the model, Network Bio is collecting blood and tissue samples from patients, along with their health outcomes, through a network of biobanks. The company is working to standardize criteria, quality control, and data from different sites to create a comprehensive dataset.
According to War on the Rocks, medical data must be compatible and verifiable for AI models to use them effectively. Network Bio is attempting to create such a dataset for specific samples and patient histories. The company's CEO, Asad Ali Ahmad, notes that each patient's tissues contain a "barcode" of disease, which has not been readable on a large scale until now.
NVIDIA's Parabricks software will prepare the data for training by mapping RNA fragments to the genome, quantifying them, and checking quality. The Nexus model will learn from RNA profiles without pre-defined diagnoses and can be used as a foundation for various tasks, including oncology. Network Bio's biobank partners include Mass General Brigham, University of Pennsylvania, and University of Colorado Anschutz.

Network Bio Launches with $50 Million Financing and World’s Largest Patient Tissue Training Dataset
Brain Pain Map
Researchers used ultrasound pulses to map deep brain area responses related to pain and mood. On August 19, authors released a preliminary scientific paper analyzing 36 participants: 19 with chronic pain and 17 with treatment-resistant depression. After brief ultrasound exposures at neighboring points in the anterior cingulate cortex, participants more often reported positive changes than after sham procedures.
The anterior cingulate cortex is a deep brain area along the brain's midline involved in experiencing pain and regulating mood. Authors checked if they could consistently target several nearby points in this area, obtain brief self-reports after each, and find points with consistent responses. An MRI scan linked exposure coordinates to individual anatomy. A double-grid ultrasound transducer accounted for skull distortion of the beam and shifted focus between points about four millimeters apart.
After each 30-second to three-minute trial, participants described any changes in pain or mood, allowing researchers to match each point with the person's immediate response. In two preliminary studies, each participant underwent both active and sham procedures on different visits. In both versions, white noise and pulse recordings sounded through headphones; in the sham procedure, the device did not deliver ultrasound energy. Responses were deemed positive in 29% of 807 responses after active exposure and 8% of 797 after sham exposure.
The response map differed between groups. For chronic pain, the greatest distinction from sham procedures was found in the anterior part of the anterior cingulate cortex, while for depression, it was in the middle section of its lower part. Participants with a higher proportion of positive responses on the first visit had greater reductions in pain or depressive symptoms 24 hours later. Authors obtained a consistent sequence in which the exposure point, rapid self-report, and comparison to sham were linked in a single experience, as reported in the preliminary scientific paper.

Researchers used ultrasound pulses to map deep brain area responses related to pain and mood. On August 19, authors released a preliminary scientific paper analyzing 36 participants: 19 with chronic pain and 17 with treatment-resistant depression. After brief ultrasound exposures at neighboring points in the anterior cingulate cortex, participants more often reported positive changes than after sham procedures.
The anterior cingulate cortex is a deep brain area along the brain's midline involved in experiencing pain and regulating mood. Authors checked if they could consistently target several nearby points in this area, obtain brief self-reports after each, and find points with consistent responses. An MRI scan linked exposure coordinates to individual anatomy. A double-grid ultrasound transducer accounted for skull distortion of the beam and shifted focus between points about four millimeters apart.
After each 30-second to three-minute trial, participants described any changes in pain or mood, allowing researchers to match each point with the person's immediate response. In two preliminary studies, each participant underwent both active and sham procedures on different visits. In both versions, white noise and pulse recordings sounded through headphones; in the sham procedure, the device did not deliver ultrasound energy. Responses were deemed positive in 29% of 807 responses after active exposure and 8% of 797 after sham exposure.
The response map differed between groups. For chronic pain, the greatest distinction from sham procedures was found in the anterior part of the anterior cingulate cortex, while for depression, it was in the middle section of its lower part. Participants with a higher proportion of positive responses on the first visit had greater reductions in pain or depressive symptoms 24 hours later.

Lung Repair Boosted
A new study on August 19 found that an antibody can strengthen a weakened signal between lung cells in older mice, replenishing their supply of repair cells for air sacs. The authors linked the decline of AT2 cells, which participate in the repair of alveoli, to weaker chemical signals from neighboring fibroblasts.
The antibody activated the Fzd5 receptor on AT2 cells, increasing their supply. After damage, AT2 cells divide and then some of them transform into AT1 cells, forming a thin surface for gas exchange. A 2018 study on mice helped identify Wnt2 as a key signal supporting the supply of dividing cells.
The new study found that this local support weakens with age in older mice, with fewer AT2 cells and lower Wnt2 production from neighboring fibroblasts. The authors then attempted to replenish the reserve directly in AT2 cells using an antibody that activates Fzd5. The treatment increased the number of AT2 cells in older mice to levels similar to those in young animals over eight weeks.

Afterlife Protocol
The authors of the Afterlife Delegation Protocol have proposed a will that, after confirmation of death, launches an AI executor. On August 15, Botao Hu and Iris Long published the project, which allows a person to create an "agency will" that defines what an autonomous program can do after their death, what data it can access, and what resources it can use.
The protocol separates the boundaries of the agent's powers from the data it collects and the software means by which it operates. The launch of the executor depends entirely on confirmation of death. The authors propose a procedure for disputing a death claim, in which the claim can be submitted with a deposit, and registry data, appointed witnesses, and prolonged absence of confirmed activity are given different weights.
The project leaves open questions, such as when the agent can speak on behalf of the deceased, how to obtain the consent of the living to use shared memories, who is allowed to stop the agent, and how it will be paid for its work. The protocol is described in the Afterlife Delegation Protocol and is available for testing in an interactive web interface, where a person can go through an interactive interview, then return to their will, change the conditions, and in a simulation, observe how the agent responds to pre-defined situations.

New Elliptic Curve Record
The AI system Claude helped discover an elliptic curve with 30 independent points, surpassing the previous record of 29. On August 20, the online registry of elliptic curves ICARM added entry #273, which features this new curve with 30 rational points and a lower bound of its rank equal to 30.
The curve's equation and the coordinates of all 30 points are published on the entry page. ICARM verifies that each point lies on the curve and confirms their independence using an exact 2-descent calculation. The previous record, set in 2024, had 29 independent points, but the new entry contains a new equation and a new list of 30 points, increasing the known lower bound from 29 to 30.
The participants in the discovery, including Claude, Levent Alpöge, and Ava Howell, are credited in the entry comment. The result can be verified using the published equation and list of points, as described in the ICARM registry.

SecureBio Detection Grant
The OpenAI Foundation has awarded SecureBio Detection $17.2 million to reduce the time from sample collection to early warning of a new pathogen from 14 to 3 days. On August 20, SecureBio Detection announced the grant, which will be used to reduce the time to result over the next year, add three cities to the nasal swab program, and increase sequencing volume.
SecureBio's approach involves collecting wastewater and nasal swabs, reading a wide range of DNA and RNA, and then searching for signs of an unusual pathogen. This method, known as metagenomic sequencing, allows for the detection of threats that are not yet on the list of known infections. The grant is focused on this stage of protection, which includes the entire process from sample collection to actionable result.
SecureBio plans to accelerate sample transportation, automate and parallelize sample preparation, and configure data processing to tap into more computing power for short periods. The average weekly volume is expected to grow to 80 billion read pairs, with each pair representing a short segment of genetic material read from both sides. The program began in 2021 as the Nucleic Acid Observatory project at the Sculpting Evolution group at the Massachusetts Institute of Technology. SecureBio will test the sensitivity of the entire chain from sample to final signal to different classes of viruses, and employees and external consultants will seek vulnerabilities that an attacker could exploit, as described in Nature Aging, July 2026.

France Allows Euthanasia
The French government has introduced a law that allows citizens to request assistance in dying under certain conditions. On August 18, President Emmanuel Macron signed law № 2026-794, which was published on August 19. This law adds the right to assisted death to the French Public Health Code, allowing adults to request assistance in dying if they have a severe, incurable illness that meets established criteria.
The law outlines a procedure for accessing assisted death, which requires five conditions to be met: the person must be at least 18 years old, a French citizen or a legal resident, have a severe, incurable illness that is advanced or terminal, experience suffering related to the illness that is unbearable or cannot be alleviated, and be able to express their free and informed will. A doctor informs the person about their condition, treatment options, palliative care, and available psychological support, after which the person can formalize their request.
A medical team, including the person's doctor, a specialist, and a medical worker from the treatment team, evaluates the illness, suffering, and free will. The team's decision is made by the first doctor, who must make a decision within 15 days of the request. After a positive decision, there is a waiting period of at least two days, during which the person must confirm their request. The law also establishes a commission to monitor the procedures and ensure that conditions and rules are respected, as reported in Le Monde, August 2026.

DAXX Protein Role
The DAXX protein keeps virus-like DNA repeats switched off in microglia, the immune cells of the brain. Removing it causes inflammation and signs of cellular aging. On August 17, a study was published in Nature Neuroscience, where authors conditionally deleted the Daxx gene in adult mice and tracked the cells.
They studied how DNA packaging and microglia state changed as a result. In mammalian DNA, there are preserved repetitive fragments of ancient retroviruses. The cell usually keeps them switched off by tightly packaging DNA. In microglia, DAXX is the protein responsible for suppressing these virus-like repeats.
The level of DAXX decreased with age in both the brain and isolated microglia of mice. In human blood, higher DAXX gene activity was associated with lower activity of almost all studied types of retroelements. To establish the sequence of events, researchers deleted Daxx in young adult mice.
LTR-retroelements, one type of virus-like DNA repeat, were activated within the first few days. On some of these regions, the H3K9me3 chemical mark, which helps to tightly package DNA, was reduced. Then, microglia activated the interferon program and other inflammatory genes.
Cells lost signs of a calm state, and damage appeared in their DNA. Later, the number of microglial cells decreased, and among the remaining cells, some appeared with signs of senescence, a state in which a cell changes its function for an extended period.

DAXX Protein Role
The DAXX protein keeps virus-like DNA repeats switched off in microglia, the immune cells of the brain, and its removal causes inflammation and signs of cellular aging. On August 17, an article was published in Nature Neuroscience, where authors conditionally knocked out the Daxx gene in adult mice and tracked the cells, studying how DNA packaging and microglia state changed.
In mammalian DNA, repetitive fragments of ancient retroviruses are preserved, and cells usually keep them switched off by tightly packaging DNA. In microglia, DAXX is the protein responsible for suppressing these virus-like repeats. The level of DAXX decreased with age in both the brain and isolated microglia of mice.

Later, the number of microglial cells decreased, and among the remaining cells, some appeared with signs of senescence, a state in which a cell changes its work for an extended period. The authors separately checked the role of PML, a protein that supports this state, and found that when Daxx and Pml genes were simultaneously removed, there were fewer cells with positive laboratory tests for senescence and more microglial cells by the eighth week.

CoQ10 Trial in Elderly
The University Medical Centre Ljubljana has registered a 10-week trial of coenzyme Q10 in people over 65 with early signs of frailty. One hundred participants will receive either 200mg of coenzyme Q10 or a placebo daily for ten weeks. The primary outcome measure will be GDF-15, a protein that indicates cellular and mitochondrial stress.
The study will also include people with low physical function test results or high vulnerability scores. Coenzyme Q10 plays a role in the functioning of mitochondria, the cellular structures where nutrients are converted into energy. Researchers will check one chain at several levels: CoQ10 concentration in plasma will show if the supplement reached the bloodstream; GDF-15 will provide a measurable signal of cellular stress; physical tests, grip strength, and frailty scales will allow comparison of this signal with how a person walks, gets up from a chair, and preserves strength.
The trial is scheduled to start in September 2026 and end in February 2027, as listed in the ClinicalTrials.gov registry.
