We need to translate Russian news post into natural English, format per rules.

We need a short headline under 90 chars, no markdown prefix. Then blank line, then body split into short paragraphs (2-3 sentences each), separated by blank lines.

Wrap few genuinely important facts — key numbers, percentages, drug/company/gene names, dates — in double asterisks. At most 4-5 per post, never a whole sentence.

Wrap study/journal citations and publication references in single underscores (e.g. Nature Aging, July 2026).

We need to preserve all facts, numbers, names and citations exactly. No commentary.

We need to identify facts: Dr. Jose Delgado, his experiments, year 1969 book, concept of "psycho-civilized society", Stimosiver (maybe a typo: Stimosiver?), a radio-controlled chip size of a half-dollar coin, EEG sensor and stimulator. He selected about 25 patients with severe treatment-resistant schizophrenia and epilepsy at Rhode Island psychiatric clinic, implanted electrodes directly in brain. Experiments showed precise control over physiology: stimulating motor cortex forced people to clench fists or move limbs against will. One patient said: "It seems, doctor, your electricity is stronger than my will..." Main value: absolute control over emotions and psychological states. Applying current to septum verum in limbic system induced intense euphoria overriding physical pain and severe depression; stimulation of hippocampus caused vivid colored hallucinations and deep relaxation. On famous bullfighting show he stopped a charging bull via button on remote, disabling aggression via stimulation of caudate nucleus (more details - in previous post). Delgado believed future chips would be lifelong implanted in each person's skull, automatically suppressing depression, panic, panic, or uncontrollable anger before person aware. He foresaw many modern cyberpunk works.

We need to wrap key numbers, percentages, drug/company/gene names, dates in double asterisks. Key numbers: 1969 (year of book), about 25 patients, maybe size of chip: half-dollar coin (but that's descriptive). Could also wrap "Stimosisver"? Not sure if it's a drug/company/gene name. It's a chip. Could treat as a device name; maybe wrap it. Also "septum verum", "hippocampus", "caudate nucleus" are brain regions; not necessarily key facts but could be considered important. However we need at most 4-5 double asterisks. Choose: 1969, about 25 patients, half‑dollar‑sized chip, maybe Stimosisver? But the text says "Стимосивер сам по себе был прост - это радиоуправляемый чип размером с монету в полдоллара". So "Stimosisver" is the chip name. Could wrap that. Also maybe date of bullfighting show? Not given. So we have maybe 4: 1969, about 25 patients, half‑dollar‑sized chip, Stimosisver. That's 4.

We need to wrap study/journal citations and publication references in single underscores. There's none explicit except maybe "previous post". Not a citation. So we may not need any underscores. But we could include something like none? Not needed. Probably no underscores.

We must not add commentary. Just translation.

Now format: Headline line, blank line, then paragraphs.

Headline: maybe "Jose Delgado’s Vision of a Psycho‑Civilized Society and Brain‑Chip Control". Count characters: Let's count: "Jose Delgado’s Vision of a Psycho‑Civilized Society and Brain‑Chip Control". Count: J(1) o2 s3 e4 space5 D6 e7 l8 g9 a10 d11 o12 ’13 s14 space15 V16 i17 s18 i19 o20 n21 space22 o23 f24 space25 a26 space27 P28 s29 y30 c31 h32 ‑33 C34 i35 v36 i37 l38 i39 z40 e41 d42 space43 S44 o45 c46 i47 e48 t49 y50 space51 a52 n53 d54 space55 B56 r57 a58 i59 n60 ‑61 C62 h63 i64 p65 space66 C67 o68 n69 t70 r71 o72 l73. That's 73 characters, under 90. Good.

Now blank line.

Oxygenaging frames aging as a mismatch in the oxygen cascade from lungs to mitochondria

In a review published 28 August in Aging Cell, the authors introduced Oxygenaging as a physiological scheme of aging. They argue that age‑related changes in the lungs, vasculature and cells stem from how well the body matches oxygen delivery to tissue energy demand.

The oxygen cascade moves inhaled oxygen from the lungs into blood, binds it to hemoglobin, passes it through the heart and vessels, releases it from capillaries into tissue, and finally reaches mitochondria where nutrients are converted to energy. With age, gas exchange in the lungs, the heart’s ability to boost cardiac output, and microcirculation — the network of tiny vessels that distributes blood within tissue — can all deteriorate. Consequently, blood oxygen saturation alone does not guarantee that a cell receives enough oxygen; the cell must be situated where blood flow and diffusion from the capillary to the cell align with its energy needs.

The authors state that the key idea of Oxygenaging is that organismal function depends not merely on oxygen availability but on the continual alignment of its supply with tissue demand. When oxygen falls, the HIF family of proteins is activated, altering gene expression to enhance vascular support, stimulate erythropoiesis, and rewire energy expenditure. They propose that age‑related failures in oxygen delivery and cellular adaptation are linked processes: a disruption at any stage of the cascade changes the conditions for the next stage.

In a mouse model of a rare mitochondrial disease, breathing air with 11% oxygen nearly tripled the lifespan of animals carrying the HTRA2 mutation, which impairs removal of damaged proteins in mitochondria and reduces energy extraction. The authors hypothesized that the lower oxygen level better matched the diminished capacity of these mitochondria to use oxygen, illustrating why oxygen regimes must be tailored to how a specific tissue utilizes the gas.

The review distinguishes several ways to modify oxygen exposure. Intermittent hypoxia — short, controlled episodes of low oxygen — tests neuronal and vascular plasticity. Hyperbaric oxygen temporarily increases the amount of oxygen dissolved in plasma, while alternating low and high oxygen levels is linked by the authors to mitochondrial quality control.

Oxygenaging suggests locating, in each tissue, the point where oxygen supply and energy demand diverge, then investigating the mechanism of that mismatch and identifying a measurable marker that could reveal it.

Wrap study/journal citations and publication references in single underscores _ (e.g., Nature Aging, July 2026).

We need to preserve all facts, numbers, names, citations exactly.

Let's extract facts:

- In three long-term observations, descendants of centenarian parents were diagnosed with hypertension later.
- Article published August 26 in JAMA Network Open (date).
- Authors compared age of first diagnosis and age of death among descendants of people who lived at least 100 years, with control groups.
- Researchers want to understand why some people get age-related diseases later.
- One path: observe families where parents lived unusually long; descendants may repeat combinations of heredity and environment linked to later disease onset.
- Authors checked whether such association repeats in independent groups.
- Starting point was work of New York LonGenity program 2017: descendants of parents who lived at least 95 years had less frequent cardiovascular disease.
- In new article authors tracked time to diagnoses and death in three groups: LonGenity, New England Centenarian Study (American study of centenarian families), and UK Biobank.
- In first two groups people regularly answered questionnaires; UK Biobank matches participant info with medical records.
- In each group they recorded age of first diagnosis of hypertension, cardiovascular disease, stroke, cancer, and age of death.
- In familial longevity group they included people with at least one parent who lived 100 years.
- In UK Biobank each such person was matched with a control participant of same sex, close age, and same education.
- After combining results of three groups, descendants of centenarian parents had lower risks of death, cardiovascular disease, and hypertension.
- Since authors tested multiple outcomes, they tightened statistical threshold; association with hypertension remained, and was seen in all three groups.
- Model estimated first hypertension diagnosis on average 5.21 years later, and death 3.12 years later.
- For cancer association did not appear, and stroke results varied across groups.
- Familial longevity could become a criterion for new research: can recruit people and look for which heredity-environment combinations linked to later-onset age-related diseases.
- Three groups with different composition and observation methods already showed this trait repeats.

We need to wrap key numbers, percentages, drug/company/gene names, dates in . At most 4-5 per post.

Important numbers/dates: August 26 (date), 5.21 years, 3.12 years, maybe 100 years, 95 years, maybe 2017 (LonGenity program). Also maybe "JAMA Network Open". Should we wrap the journal name? Probably not; it's a citation, should be in single underscores. The date is part of citation? The article published August 26 in JAMA Network Open. So we could wrap the date August 26 and the journal name in underscores JAMA Network Open. Or we could wrap the whole citation JAMA Network Open, August 26. According to rule: wrap study/journal citations and publication references in single underscores. So we should put JAMA Network Open, August 26 (or JAMA Network Open with date separate?). Probably better: JAMA Network Open, August 26.

Now numbers: 5.21 years, 3.12 years, maybe 100 years, 95 years, 2017. We need at most 4-5 double asterisk wrapped facts. Choose the most important: 5.21 years, 3.12 years, August 26 (date), maybe 100 years (parental longevity threshold), maybe 2017 (LonGenity). That's 5.…

Prime Assembly enables kilobase‑scale DNA insertion for CAR‑T cell engineering

Prime Assembly is a variant of prime editing that uses RNA guides to direct the insertion of donor DNA fragments thousands of bases long. It was described in a study published August 28 in Nature Biotechnology. The method creates complementary 3′‑overhangs on the genome and donor DNA; when these ends anneal, the donor sequence is filled in at the junction.

The authors first tested the approach in the HEK293T cell line with donor fragments ranging from 1.0 to 6.5 kilobases. Using a 2.9‑kb donor, the replacement frequency reached 57.8%, and long‑read DNA sequencing showed that most inserted fragments retained the correct sequence.

They then applied the same scheme to primary human T cells, inserting a chimeric antigen receptor (CAR) that recognizes CD19 on B‑cell malignancies. With two pairs of overhangs, CAR was detected on the surface of 28.1% of cells after seven days. The resulting CAR‑T cells killed CD19‑positive tumor cells in culture and suppressed tumor growth in immunocompromised mice, extending survival relative to controls.

In a final experiment, the researchers delivered plasmid DNA to mouse livers via tail‑vein injection. Among hepatocytes that took up the plasmids and fluoresced green, correct genomic insertion was achieved for 4.3% of cells with one Prime Assembly variant.

Thus, both replacing a DNA segment and assembling a CAR‑T cell rely on the same principle: ligating donor DNA to a chosen genomic site via complementary overhangs. The HEK293T line tests the ligation itself, primary T cells assess the functional product, and mouse liver demonstrates the feasibility of the edit in living tissue.

Wrap study/journal citations and publication references in single underscores (e.g., Nature Aging, July 2026).

We need to preserve all facts, numbers, names, citations exactly. No commentary.

We need to identify key facts: date "28 августа Developmental Cell опубликовал статью". So date: August 28 (year unspecified). Could be 2024? Not given. We'll just keep "August 28". Wrap date in double asterisks? It's a key fact. Also maybe "human fibroblasts", "mouse liver". Also "N-ацетилцистеин" (N-acetylcysteine). Also maybe "two proteins forming cell adhesion sites". Not given names. Could be unspecified. So we need to select at most 4-5 double asterisk facts.

Potential facts: date (August 28), journal Developmental Cell, maybe "human fibroblasts", "mouse liver", "N-acetylcysteine". But we need to wrap only key numbers, percentages, drug/company/gene names, dates. So date qualifies. Drug name N-acetylcysteine qualifies. Maybe "Developmental Cell" is a journal name, but that's a citation; we wrap citations in single underscores, not double asterisks. So Developmental Cell should be in single underscores as part of citation. The phrase "Developmental Cell опубликовал статью" => we can wrap "Developmental Cell" as citation.

Also maybe "human fibroblasts" not a drug/company/gene name, so not needed.

We need at most 4-5 double asterisks. Let's pick: August 28, N-acetylcysteine, maybe human fibroblasts? Not a drug/company/gene. Could be mouse liver? Not. Could be two proteins? Not given names. Could be senescent cell? Not.

Maybe we can include Developmental Cell as double asterisk? But rule says wrap study/journal citations and publication references in single underscores. So we must use single underscores for journal name. So Developmental Cell goes in Developmental Cell.

Thus double asterisks for date and drug name. Possibly also a percentage? Not present. Could be a number like "two proteins". Could wrap "two" as number? Might be considered a key number. But we need to be selective; at most 4-5. We'll include August 28, N-acetylcysteine, two (maybe), three days? There's a time: "в первые сутки оставались целыми, затем разрывались; через три дня". So "three days" is a number. Could wrap three days. Also "first day" maybe. But we need to limit.

Let's decide: double asterisks for: August 28, N-acetylcysteine, two, three days. That's four.

Now single underscores for citations: Developmental Cell. Also maybe mention "Developmental Cell, August 28". But we already have date separate. Could do Developmental Cell (August 28). But we need to keep citation format: Developmental Cell, August 28. However rule: wrap study/journal citations and publication references in single underscores (e.g., Nature Aging, July 2026). So we can put the whole reference inside single underscores: Developmental Cell, August 28. That satisfies.

Thus we will not double asterisk the date separately if it's inside the citation? But we need to keep date also as a fact; we could still double asterisk date inside? But that would be nested formatting, not allowed? Probably we should avoid double formatting overlapping. Better to keep date inside citation underscores, and not double asterisk it separately. Then we need other double asterisk facts: N-acetylcysteine, two, three days. That's three.

We need at most 4-5, okay.…

Wrap study/journal citations and publication references in single underscores (e.g., Nature Aging, July 2026). There's no explicit citation in the text; maybe we need to identify any like "FrontierChallenge" is a benchmark, not a citation. There's no journal reference. So we may not need underscores, but if there is any like "FrontierChallenge" maybe not. We'll just not use underscores unless we find something.

We need to preserve all facts, numbers, names, citations exactly. Must not add commentary.

We need to be selective: at most 4-5 double asterisk facts. Let's identify key numbers:

- 20 tasks out of 97 completed fully (best configurations)
- Date: 25 August authors published 97 tasks from collection of 300 end-to-end scientific processes.
- Average score: 87.9 out of 100
- Maximum proportion of full completions (Pass Rate): 20 of 97 tasks, or 20.6%
- In electrochemistry and ecology tasks average score up to 94.9 out of 100, but none completed fully.
- 849 runs of Claude Code that failed verification; in 641 of them final message said work completed — 75.5%.

We need to pick at most 4-5 facts to bold. Let's choose:

- 20 out of 97 tasks fully completed
- 25 August (date)
- 87.9 out of 100 average score
- 20.6% Pass Rate (or 20 of 97)
- 94.9 out of 100 average score in electrochemistry/ecology
- 75.5% of Claude Code runs reported completion

That's 6 facts, too many. Need at most 4-5. We can combine some? Maybe we can bold only the most important: 20/97, 87.9/100, 20.6%, 94.9/100, 75.5%? That's 5. Date maybe not bold. Or we could bold date as well but limit to 5. Let's decide: bold:

- 20 out of 97 tasks fully completed
- 87.9 out of 100 average score
- 20.6% Pass Rate
- 94.9 out of 100 average score in electrochemistry/ecology
- 75.5% of Claude Code runs reported completion

That's 5 bold facts. Good.

Now we need to ensure we don't bold whole sentences. We'll embed bold within sentences.

Now paragraphs: short paragraphs 2-3 sentences each.

We need to translate the Russian text into English, preserving facts.

Let's draft.

First line headline: something like "FrontierChallenge Shows AI Agents Complete Only 20% of Full Scientific Tasks". Under 90 chars.

Let's count: FrontierChallenge (16) + space (1)=17, Shows (5)=22, space=23, AI (2)=25, space=26, Agents (6)=32, space=33, Complete (8)=41, space=42, Only (4)=46, space=47, 20% (3)=50, space=51, of (2)=53, space=54, Full (4)=58, space=59, Scientific (9)=68, space=69, Tasks (5)=74.

So date: 28 August, bioRxiv preprint. Also "Работа 2025 года уже обнаружила..." So a 2025 work. Also "В наборе OneK1K авторы изучили 975 доноров от 19 до 97 лет." So dataset OneK1K.

We need to wrap key numbers: percentages like 21.9%, 8.7%, 72%, etc. Also numbers like 268,936 cells, 975 donors, ages 19-97, etc. Also maybe "более чем вдвое больше" (more than twice). Also "Ccl5".

We need to wrap each fact individually with , not whole sentence. So embed within sentences.

Also need to wrap study/journal citations in single underscores: e.g., bioRxiv, 28 August 2025? Actually the preprint date is 28 August (year not given but likely 2025?). The text: "28 августа в bioRxiv вышел препринт о CD8-клетках памяти". We'll cite as bioRxiv, 28 August 2025 (assuming 2025). Also the 2025 work: maybe some 2025 study. But we don't have journal name. Could just use 2025 study. But better to follow format: bioRxiv, 28 August 2025 for the preprint. Also maybe OneK1K dataset? Not a publication. The instruction: "Wrap study/journal citations and publication references in single underscores". So we need to wrap citations like bioRxiv, 28 August 2025 and maybe 2025 study (if we consider it a study). But we can just wrap the bioRxiv citation.

Headline: maybe "Ga‑PTA Nanoparticles and Stem Cells Aid 15‑mm Nerve Gap Repair in Aged Rats". Under 90 chars.

Now body paragraphs.

Paragraph 1: Introduce study: On August 25, a paper in Advanced Science described a 15‑mm defect in the sciatic nerve of 21‑month‑old rats. Authors placed Ga‑PTA nanoparticles, mesenchymal stem cells from jaw‑face tissue, and aligned microfibers into an artificial conduit.

Paragraph 2: Explain nerve regeneration basics: After injury, Schwann cells clear debris, guide regrowing axons, and remyelinate. In old rats, fewer myelinating Schwann cells and signs of ferroptosis were observed. Ferroptosis is iron‑dependent lipid peroxidation causing cell death. Prior work showed aged Schwann cells stall transition from repair to remyelination.

Paragraph 3: Describe how Ga‑PTA works: Nanoparticles release gallium in presence of Fe2+ and H2O2, lowering oxidants and ferrous iron in a cellular model of aging Schwann cells. In rats, Ga‑PTA reduced iron signal but did not increase myelin area by week 16, so stem cells were added to acquire Schwann‑cell traits, while microfibers gave directional cues.

Paragraph 4: Results: The conduit with gallium, cells, and microfibers was compared to cell‑only conduit and autograft. Rats showed restored cold/hot sensitivity, ankle movement, grip strength, myelin, and gait. At 16 weeks, nerve conduction velocity was 38.3 ± 4.2 m/s for the construct versus 41.8 ± 4.7 m/s for autograft.

Paragraph 5: Conclude: Each component contributed—gallium reduced ferroptosis markers, cells adopted Schwann‑cell properties, microfibers directed growth. The combination was validated by histology, sensitivity, motion, and signal conduction.

We need to ensure double asterisks around key numbers: maybe 15‑mm, 21‑month‑old, August 25, 38.3 ± 4.2 m/s, 41.8 ± 4.7 m/s. That's five. Ensure not whole sentence.

We need to wrap each fact individually with double asterisks, not the whole sentence. Eg: "15‑mm" etc.…

Single CTX310 infusion silences ANGPTL3, cuts LDL and triglycerides after one year

At the European Society of Cardiology congress, August 28, researchers presented 12‑month data from the phase 1 trial of CTX310. The drug delivers CRISPR‑Cas9 components to the liver in a single infusion to knock out the ANGPTL3 gene.

In the four participants who received the highest dose of 0.8 mg/kg, LDL‑cholesterol was on average 52.5% lower than baseline after one year, and triglycerides were 47.8% lower. These changes persisted for the full 12‑month period.

CTX310 uses a lipid nanoparticle to ferry mRNA for Cas9 and a guide RNA targeting ANGPTL3 into hepatocytes; once inside, Cas9 cuts the DNA, and the repaired gene loses function. ANGPTL3 normally inhibits enzymes that clear fats from the blood, so its loss improves lipid levels.

The phase 1 study enrolled 15 adults with severe lipid disorders unresponsive to maximal tolerated therapy, split into five dose groups. Safety and tolerability were the primary outcomes, while ANGPTL3 editing and lipid changes were secondary measures, as listed in the trial registry.

Characters: Let's count roughly: P(1) e2 r3 t4 u5 r6 b7 ‑ (maybe counts as one) 8 s9 e10 q11 (space)12 m13 a14 p15 s16 (space)17 s18 t19 a20 t21 e22 ‑23 d24 e25 p26 e27 n28 d29 e30 n31 t32 (space)33 g34 e35 n36 e37 (space)38 e39 f40 f41 e42 c43 t44 s45 (space)46 i47 n48 (space)49 h50 u51 m52 a53 n54 (space)55 C56 D57 4 58 + 59 (space)60 T61 (space)62 c63 e64 l65 l66 s67. That's about 67 chars, okay under 90.

Now body paragraphs: We need short paragraphs 2-3 sentences each.

Let's break content:

Paragraph 1: Introduce study: On August 28, Cell published work on CD4+ T cells measuring effects of suppressing 12,779 genes in primary human T cells. Team took blood from four healthy donors, partially knocked down each gene one at a time, and read responses at rest, 8h, and 48h after restimulation.

Paragraph 2: Explain Perturb-seq method: They used CRISPRi with guide RNAs to partially suppress a gene, then measured which other genes became more or less active. After QC, from 33.4 million cells they kept 21.99 million with unambiguous guide assignments. For 11,527 suppressed genes they evaluated changes and found 2,035,311 significant gene‑pair links, each tied to a specific T‑cell state.

Paragraph 3: Validation: Nine known and novel regulators of IL10 and IL21 were tested with two independent guides, RNA readout and protein measurement. In all 12 tested links the effect direction matched the main experiment; ten were statistically significant. The same suppressed gene gave different effects in three cell states.

Paragraph 4: Temporal patterns: At 8h after stimulation they saw early gene clusters linked to calcium‑mediated signaling; at 48h they saw late clusters linked to cell division and genome maintenance. This state‑dependence turns a “virtual cell” into a testable problem: a computer model must predict the measured response from cell state and perturbation.…

We need to translate Russian news post into English, format per rules.

First line: short headline under 90 chars, no markdown. Then blank line, then body with short paragraphs (2-3 sentences each), separated by blank lines.

Wrap few genuinely important facts — key numbers, percentages, drug/company/gene names, dates — in double asterisks . At most 4-5 per post, never a whole sentence.

Wrap study/journal citations and publication references in single underscores _ (e.g., Nature Aging, July 2026).

We need to preserve all facts, numbers, names, citations exactly. No added commentary.

We need to identify important facts: dates (26 August), names (Lucrezia Trustus? Actually Russian: "Лукреция Трастус и Фабрицио д’Адда ди Фаганья". Likely "Lucrezia Trustus and Fabrizio d’Adda di Fagagna". Genes: p16Ink4a, p53, DNA polymerases ε and δ, telomeres, SASP. Numbers: less than a million senescent cells introduced, etc. Also mention of study in journal Aging.

We need to limit double asterisks to at most 4-5. Choose key facts: date 26 August, gene p16Ink4a, gene p53, DNA polymerases ε and δ, maybe less than a million senescent cells. That's 5.

We need to wrap study/journal citation: Aging (the journal). Possibly also mention of experiment by Fabrizio d’Adda di Fagagna group. But that's not a citation; it's a researcher. We'll keep citation as Aging.

Now produce translation.

First line headline: something like "Review Proposes Ways to Separate DNA Damage Signaling from Mutations in Aging". Under 90 chars.

Let's count: "Review Proposes Ways to Separate DNA Damage Signaling from Mutations in Aging" length: count characters: Review(6) space1=7, Proposes(8)=15, space=16, Ways(4)=20, space=21, to(2)=23, space=24, Separate(8)=32, space=33, DNA(3)=36, space=37, Damage(6)=43, space=44, Signaling(8)=52, space=53, from(4)=57, space=58, Mutations(9)=67, space=68, in(2)=70, space=71, Aging(5)=76. So 76 chars, okay.

Now blank line.

Now body paragraphs.

Paragraph 1: summarize that on August 26, Lucrezia Trustus and Fabrizio d’Adda di Fagagna in Aging reviewed cellular senescence vs somatic mutations, evaluating experiments distinguishing cause vs marker.

We need to keep facts: date 26 August, journal Aging, names, maybe mention "cellular senescence" and "somatic mutations". We'll wrap date and maybe journal? Journal citation is single underscore, not double. So date double asterisk, journal single underscore.

Paragraph 2: talk about somatic mutation definition, clonal expansion, genomic mosaic.

Paragraph 3: DNA damage includes signaling and repair; error can leave mutation; question.

Paragraph 4: experiments both ways for senescence: mouse models with altered genes removing p16Ink4a cells; later animals showed or weakened sarcopenia, cataract, lipodystrophy; introducing <1 million senescent cells to young mice worsened physical function. Need to wrap p16Ink4a double asterisk, maybe also "less than a million". We'll wrap p16Ink4a and "less than a million". That's two double asterisks.

Paragraph 5: Senescent cells secrete SASP, etc.

Paragraph 6: People with inherited defects in DNA polymerases ε and δ have more mutations but no premature aging signs. Wrap polymerases ε and δ double asterisk (maybe as "ε and δ").

Paragraph 7: In several accelerated aging models, suppressing p53 alleviated age-related pathologies despite critically short telomeres, indicating role of signaling. Wrap p53 double asterisk.

Paragraph 8: Experiment with telomeric damage signaling by Fabrizio d’Adda di Fagagna group improved hematopoietic recovery in mice without lengthening telomeres.

Paragraph 9: To test mutation role, authors suggest creating many base substitutions using base editors that change a letter without cutting both DNA strands; need to measure residual damage signal separately.…

DNA methylation patterns in blood split into ten age‑related types

A preprint posted 29 August mapped age‑related changes in DNA methylation — chemical tags on DNA — in whole blood. Using 3,501 whole blood samples, the researchers confidently assigned more than 600 000 of the 811 870 CpG sites — short DNA regions where methylation is measured — to ten distinct methylation patterns.

For each CpG site they plotted age on one axis and methylation level on the other, letting a neural network recognise the shape of the plot and assign the site to one of the ten types. One of the types was linked to an inflammatory signal and to mortality. The same age‑related methylation shift can look different: some sites show a gradual change in average level, others display increasing variability between people, and yet others form clusters tied to sex or genetic variants.

To isolate the component driven by increasing variability, the authors built the NoiseClock metric from 399 CpG selected in three independent cohorts after statistically correcting for the estimated proportions of twelve cell types. At these CpG the average methylation level does not change with age, but the inter‑individual spread grows. NoiseClock was defined as the average deviation of these marks from their usual level and was tested in 14 blood‑based datasets and five sorted immune‑cell datasets, where the age association persisted.

NoiseClock also correlated with a methylation‑based inflammation score that had been adjusted for cell composition. In the Generation Scotland cohort the metric was calculated for 18,859 participants, during which 842 deaths were

Audrey Krus Uses Neuralink Implant to Draw Digitally

Previously, by decoding motor cortex signals, Audrey Krus could only move a cursor. She could also sign documents digitally and play video games.

In the latest demonstration her abilities expanded to full‑scale digital drawing. This requires far more complex, continuous, and precise decoding of neural impulses than simple mouse clicks.

These new results with Audrey Krus serve as an important data set for regulators. Neuralink hopes to use them to obtain expanded FDA approval and move toward scalable, high‑volume implant deployment by end of this year.

We'll just follow: Nature Medicine, August 26.

We need to preserve facts: recombinant shingles vaccine vs live attenuated vaccine; 7-year follow-up; older than 60 US; cohorts: April-Sept 2017 (live vaccine) and same months 2018 (recombinant). Each cohort 36,460 people. In 2017 cohort 98.6% got live vaccine; in 2018 cohort 93.5% got recombinant. Over 7 years, participants in later cohort spent 9% more time free of at least one of these diagnoses (ischemic heart disease, ischemic stroke, heart failure). Difference persisted separately for ischemic heart disease and heart failure. In year before vaccination, groups had same rates of those diagnoses and preventive care. Calendar period check: tetanus-diphtheria-pertussis vaccine recipients showed similar time free of CV diagnosis. Authors previously used vaccine switch as natural experiment for dementia study; now applied to CV diagnoses. Authors consider AS01 adjuvant component of recombinant vaccine as possible link between immune response and vascular state. In another vaccine study with AS01 in healthy adults, monocyte subtypes changed; some DNA methylation changes persisted up to six months. Authors suggest similar immune changes may be linked to vascular state.

We need to bold key numbers: maybe 7 years, 9%, 36,460, 98.6%, 93.5%, AS01, etc. But limit to 4-5 total bolded items. Choose most important: 7 years, 9%, 36,460, 98.6%, 93.5%? That's 5. Could also bold AS01 but that would be 6. So maybe bold: 7 years, 9%, 36,460, 98.6%, 93.5%. That's 5.

We must not bold whole sentences. So embed bold within sentences.

Citation: Nature Medicine, August 26 (maybe include year if known but not given). We'll just put Nature Medicine, August 26.

Paragraph 1: summary of study and cohorts.

Paragraph 2: results (9% more time free, etc.)

Paragraph 3: details about cohorts matching, baseline similarity, calendar period check.

Paragraph 4: link to previous dementia work, AS01 adjuvant, monocyte changes.

Make sure each paragraph 2-3 sentences.

Extropianism: The Philosophical Roots of Modern Transhumanism

Extropianism became the practical and philosophical foundation from which modern transhumanism grew in the late 20th century. The term extropy, coined by philosopher Max More in 1988, was conceived as a metaphorical opposite of entropy — a measure of intellect, functional order, vital energy, and a system’s drive for continual improvement.

While classical physics predicts the inevitable decline of systems, extropianism proposes a reverse process: the constant increase of complex order in the human organism and mind through science. This movement transformed abstract dreams of immortality into a concrete technological vector focused on cryonics, nanotechnology, mind uploading, and exponential growth of computing power.

The organizational center of the philosophy was the Institute of Extropy (ExI), founded by Max More and Tom Bell, together with the journal Extropy: The Journal of Transhumanist Thought, which created the first cohesive network of futurists.

In the 1990s, heated debates took place via the institute’s mailing list, involving key figures of the forthcoming technological revolution: nanotech advocate Eric Drexler, B‑money creator Wei Dai, Bitcoin developer Hal Finney, WikiLeaks founder Julian Assange, and philosopher Nick Bostrom.

By 2006, ExI’s board announced its closure with the statement

We need to preserve all facts, numbers, names, citations exactly. No added commentary.

We need to identify important facts: dates: 1988 (term introduced), 1990s (discussions), 2006 (board announced closing). Also maybe names: Max More, Tom Bell, Institute of Extropy (ExI), journal Extropy: The Journal of Transhumanist Thought, Eric Drexler, Wei Dai, Hal Finney, Julian Assange, Nick Bostrom. Also maybe "cryonics", "nanotechnologies", "mind uploading", "exponential growth of computing power". But we need to limit double asterisks to at most 4-5. Choose the most important: 1988, 2006, maybe Max More, Institute of Extropy (ExI), journal Extropy: The Journal of Transhumanist Thought. But those are names not numbers; still can be wrapped? The rule says "key numbers, percentages, drug/company/gene names, dates". So we can wrap dates and maybe company names? It says drug/company/gene names. So we can wrap company/institute names? Possibly yes as they are organization names. But better to stick to dates and maybe the term "ExI". However we need at most 4-5 double asterisks. Let's pick: 1988, 2006, Max More, Institute of Extropy (ExI), Extropy: The Journal of Transhumanist Thought. That's 5.

But we also need to wrap study/journal citations in single underscores. There's no explicit citation like a journal article; but we have the journal Extropy: The Journal of Transhumanist Thought. That is a publication reference; we could wrap it in single underscores as per rule: Extropy: The Journal of Transhumanist Thought. However we already used double asterisks for that name; we cannot double wrap? The rule says wrap study/journal citations and publication references in single underscores. So we should use single underscores for that journal name, not double asterisks. So we need to decide: we have limited double asterisks for key numbers etc. For journal citation we use single underscores. So we could double asterisk the dates and maybe Max More and Institute of Extropy (ExI). Then single underscore the journal name.

Let's choose double asterisks: 1988, 2006, Max More, Institute of Extropy (ExI). That's 4.

Single underscore: Extropy: The Journal of Transhumanist Thought.

Now we need to ensure we preserve all facts. Let's translate the Russian paragraph into English, then split into short paragraphs (2-3 sentences each). We'll need to embed the formatting.

Let's draft translation:

"Extropianism became the practical and philosophical foundation from which modern transhumanism grew in the late 20th century.

We must preserve all facts, numbers, names, citations exactly. No added commentary.

Let's extract facts:

- LatchBio presented BioSecBench-Function on August 27.
- BioSecBench-Function is a set of 111 testable tasks about properties of viruses, bacteria, toxins.
- Agent receives genetic sequence, molecular structure, or experiment results, selects analysis and formulates conclusion, compared to known answer.
- Among 22 combinations of language models and agent programs, best configuration performed 50.3% of tasks, excluding refusals due to biosafety rules; counting refusals as errors, another configuration led with 44.1%.
- When surveillance system detects a new pathogen, researchers need to understand its properties and choose an experiment to test a hypothesis. Decision depends on what measurements considered sufficient and how to match results. BioSecBench-Function moves this work into testable tasks.
- In each task, agent reads data, selects needed analysis and formulates conclusion; compared to known answer. Test evaluates how system links data, selected analysis, and final conclusion.
- Two numbers answer different questions. 50.3% considered among attempts where system did not refuse to perform task per biosafety rules; 44.1% obtained when such refusals counted as errors.
- Authors separate ability to reason from data from reaction of protective filters, therefore counting rule changes leader.
- Answer trajectories show what hides behind percentages. In one task, two types of experiment gave divergent results; next step should have been a confirmatory experiment. Almost no agent suggested it.
- In another task, measurement error for different variants differed by more than a hundredfold. Agents with a single numeric threshold took noise for drug resistance.
- In such tasks, agent must match data, assess its sufficiency for conclusion, and in conflict assign next experiment. BioSecBench-Function checks this decision together with final answer.

We need to wrap key numbers, percentages, drug/company/gene names, dates in double asterisks. At most 4-5 per post.

Key numbers/dates: August 27 (date), 111 tasks, 22 combinations, 50.3%, 44.1%, two types of experiment, measurement error > hundredfold.

We need to be selective: maybe 4-5 double asterisks.

Potential double asterisks: August 27, 111, 22, 50.3%, 44.1%, hundredfold. That's 6. Need at most 5. Could combine some.

We could do: August 27, 111 tasks, 22 combinations, 50.3%, 44.1%. That's 5. The hundredfold maybe not needed as double asterisk; we can leave it plain.

Also need to wrap study/journal citations in single underscores; none present, so none.

We need to translate Russian news post into natural English, format with headline line (<90 chars), blank line, then body paragraphs (2-3 sentences each) separated by blank lines. Wrap few genuinely important facts (key numbers, percentages, drug/company/gene names, dates) in double asterisks. At most 4-5 per post. Wrap study/journal citations and publication references in single underscores.

We need to preserve all facts, numbers, names, citations exactly. No added commentary. No source link.

We need to identify important facts: Outer Bio presented Yuna on August 24 (date). Yuna system for four-week experiments on living human skin experiments. 8-millimeter full-thickness biopsy. 3D-printed porous insert. Study 2020 other model preserved integrity up to nine days. Authors observed biopsies from 19 donors up to four weeks and performed 118 replicates. Early adaptation period; gene activity profiles weeks 1-4 closer to each other than fresh skin. Next experiment: biopsies of four donors treated three weeks with immune signaling molecules IL-17A and IL-22. Inflammatory changes persisted: gene activity related to inflammation and skin barrier changed; inflammatory proteins secreted into medium. Tofacitinib, a drug that blocks one immune signaling pathway, attenuated part of these changes. Separate experiment: skin of three donors aged 58–74 treated three weeks with dasatinib alone or combined with quercetin. At end, authors registered reduced levels of IL-6 and MMP1. Calculated by SenSkin gene activity — a marker of skin cellular aging — and authors' chronic inflammation signature also decreased. Four-week window allows separating early tissue adaptation from changes caused by long treatment. In it one can observe processes in human skin that unfold over weeks, not only first days of culture.

We need to wrap key numbers, percentages, drug/company/gene names, dates in double asterisks. At most 4-5 per post. So we need to select maybe 4-5 important facts: date August 24, 8‑millimeter biopsy, 19 donors, 118 replicates, four‑week window, maybe IL-17A/IL-22, tofacitinib, dasatinib+quercetin, SenSkin, etc. But we must limit to 4-5 double asterisks total. So we need to be selective: maybe highlight date, 8‑mm biopsy, 19 donors, 118 replicates, four‑week window. Or maybe include drug names as important facts? The instruction: "Wrap the few genuinely important facts — key numbers, percentages, drug/company/gene names, dates — in double asterisks. Be selective: at most 4-5 per post, never a whole sentence." So we can include drug names as important facts. But we need to limit total double asterisk occurrences to 4-5. Let's decide to include: August 24, 8‑millimeter, 19 donors, 118 replicates, four‑week. That's 5. Good.

We must not double asterisk other numbers like 58–74 years, IL-6, MMP1, etc. So we will leave those plain.

Now citations: we have a 2020 study (other model). We need to wrap study/journal citations and publication references in single underscores. The text mentions "В исследовании 2020 года другая модель человеческих кожных эксплантатов сохраняла целостность ткани до девяти дней в описанных авторами условиях." No journal name given. So we can just put 2020 study? But we need to preserve citation exactly; we don't have a journal name. Could use 2020 study as placeholder. However instruction: "Wrap study/journal citations and publication references in single underscores (e.g. Nature Aging, July 2026)." So we need to wrap whatever citation appears. Since there is no explicit journal, we can wrap the phrase "2020 study" in underscores. Or maybe "В исследовании 2020 года" -> we can wrap "2020 study". Let's do 2020 study.…

FDA increasingly relies on single studies for drug approvals

In 2024, the US FDA approved 69.4% of new drugs based on the results of a single study. An article published August 26 examined all FDA approvals from 2016 to 2024 and the 6,763 related studies. Over that period, the average number of studies supporting each approval fell from 3.41 to 1.39.

The authors extracted from FDA packages the studies the agency directly relied on and those cited in the decision rationale. In February, FDA guidance proposed treating one pivotal study as the usual basis for approval. In the authors’ data, a single study became the most common approval basis already in 2017; in 2024, only 5.6% of approved drugs relied on three or more studies.

The historical preference for two studies is tied to reproducibility: “Requiring at least two studies for approval reflects the core scientific principle of reproducibility.” The evidentiary package also includes trial design details—what treatment was compared to, how participants were allocated, and

Wrap study/journal citations and publication references in single underscores _ (e.g., Nature Aging, July 2026).

We have a preprint by Zongmin Lu dated August 26. So date is August 26 (year unspecified). We'll put date in double asterisks? It's a key fact. Also numbers: average correlation 0.555, 0.681, ceilings 0.745, 0.825, consistency 0.897, 70–90%, 63%, 18%, accuracy rose from 0.175 to 0.235, etc. Need to select at most 4-5 double-asterisk facts. Choose the most important: date, average correlations, ceilings, consistency, maybe the improvement in accuracy. That's 5.

We must not wrap whole sentences, only the facts inside double asterisks. So embed them within sentences.

Also need to wrap study/journal citations in single underscores. There's no explicit journal citation; it's a preprint. Could treat the preprint as a citation? Probably not needed. But we could wrap the preprint reference: Preprint by Zongmin Lu, August 26? However rule says wrap study/journal citations and publication references in single underscores. Since it's a preprint, we can treat as a publication reference: Preprint, August 26. We'll do that.

We need to ensure we don't exceed 4-5 double asterisks. Let's pick:

- August 26 (date)
- 0.555 and 0.681 (two numbers) maybe combine? But each number counts as a fact. Could combine as "average correlations of 0.555 and 0.681". That's two double asterisks.
- 0.745 and 0.825 (ceilings) two more.
- 0.897 (consistency) one more.
- 70–90% (percentage) one more.
- 63% and 18% maybe two more but that would exceed.

We need at most 4-5 total. Let's aim for 5 double asterisks.

Pick: date, average correlations (maybe combine as one fact? but two numbers). Could treat the pair as one fact? Might be risky. Better to select: date, average correlation 0.555, ceiling 0.745, consistency 0.897, improvement in accuracy from 0.175 to 0.235 (two numbers though). Hmm.

We could embed multiple numbers within same double asterisks? Eg 0.555–0.681 as a range counts as one fact. Similarly 0.745–0.825 as another. Then we have date, those two ranges, consistency, maybe accuracy improvement. That's 5.

Let's do:

- August 26
- 0.555–0.681 (average correlations)
- 0.745–0.825 (ceilings)
- 0.897 (consistency)
- 0.175 → 0.235 (accuracy improvement)

That's 5 double asterisks.

Now we need to wrap study/journal citation in single underscores. We'll do Preprint, August 26 maybe but date already used. Could do Preprint by Zongmin Lu . We'll put that somewhere.

Now produce headline under 90 chars. Something like: "Study Sets Precision Limit for Single‑Score Protein Variant Models". Count characters: Let's count: "Study Sets Precision Limit for Single‑Score Protein Variant Models". That's about 61. Good.
