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

First line: short headline under 90 chars, no markdown, no '#'.

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 facts, numbers, names, citations exactly. No added commentary.

We need to identify important facts to bold: numbers like 30–70%, dates (2 сентября), maybe names: Masayoshi Suda, Tamara Chkonia, James Kirkland, Geromedicine, p16, p21, CXCL1, CXCL5, CXCL8, PDGF-AA, TNFα, IL-6, eNOS, etc. Also percentages like 1–1.5% body mass. Also maybe mention "obese mice". Also mention "after intervention". But limit to 4-5 bolded items.

We need to be selective: at most 4-5 per post. So choose maybe: 2 сентября, 30–70%, p16, p21, 1–1.5%? That's 5. Or maybe include drug name? There's no specific drug name given, just senolytics. Could bold "Geromedicine". But we need to keep within limit.

We also need to wrap study/journal citations in single underscores. The citation: "Масаёси Суда, Тамар Чкония и Джеймс Киркленд опубликовали в Geromedicine обзор о стареющих клетках при ожирении." So we need to underscore the journal: Geromedicine. Also maybe date? The date is part of headline? We'll bold date.

Thus we will have: Geromedicine as citation.

Now produce headline: maybe "Senolytics must be tailored to cell type and tissue, review says". Under 90 chars.

Check length: "Senolytics must be tailored to cell type and tissue, review says" length ~55.

Now blank line, then body paragraphs.

We need to split into short paragraphs 2-3 sentences each.

Let's craft paragraphs:

Paragraph 1: Introduce review, authors, date, journal.

Paragraph 2: Explain senolytics, SASP, inflammatory vs growth signals, residual senescent cells after treatment (30–70%), changes in CXCL1/5/8 and PDGF-AA.

Paragraph 3: Mechanisms: protective anti-apoptotic pathways, inflammatory SASP makes cells dependent, senolytics temporarily inhibit.

Paragraph 4: In obese mouse fat tissue, differences by cell type: p21+ progenitors and immune cells have more inflammatory signals; p16+ endothelial subtype more inflammatory with DNA damage, TNFα, IL-6.

Paragraph 5: Time after stress changes marker role: irradiated mice p21+ at 1 month, p16+ accumulate by month 4, clearance only effective late; p16+ immune cells help tolerate infection and irradiation.

Paragraph 6: Tissue, stress, time determine harm vs benefit; endothelial cells ~1–1.5% body mass but line vasculature; exposed to glucose, fatty acids; senescent endothelial SASP drives inflammation and secondary senescence; creates feedback loop with other inflamed cells.

Paragraph 7: Genetic mouse model: drug removed p16+ senescent endothelial cells; obese mice after intervention had reduced fat mass, lipid accumulation, improved glucose tolerance, increased eNOS expression.

Paragraph 8: Conclusion: senolytic design must consider cell type, tissue, stress source; targeting vascular endothelium links blood and fat tissue.

Now we need to bold key numbers/names/dates: choose 2 сентября, 30–70%, p16, p21, 1–1.5% (maybe also eNOS? but that's a gene name; could be bold but we already have 5). We'll keep those 5.

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

Also need to wrap journal citation in single underscores: Geromedicine.

Now produce final answer.

Check for any extra formatting: no markdown except bold and underscores. Headline line no markdown.

Make sure blank line after headline, then paragraphs separated by blank lines.

US Launches National AI Resource Access Center for Science

The United States is establishing a national AI‑resource access center for science. On September 1, the University of California, San Diego announced that the U.S. National Science Foundation has awarded $35 million over five years to the NAIRR Operations Center.

The center will link researchers, educators, and students with computing power, data, AI models, software, and technical support. According to the NSF award notice, the agreement begins October 1 2024 and runs through September 30 2031.

In its first two and a half years, the NAIRR pilot — an NSF program that connects research and education teams with AI resources — has engaged about 900 teams and instructors across all 50 states.

NAIRR‑OC will be led by the San Diego Supercomputer Center at UC San Diego together with the Texas Advanced Computing Center at the University of Texas at Austin. Private, federal, and academic organizations will supply the computing, data, models, and software for research.

The operations center will coordinate providers and pool their resources into a single national online service. Teams can request needed resources in one place, then receive documentation, training, and technical assistance; forums and feedback channels will help the center adapt to user needs.

The center will be built on the existing national services of those two centers, transferring suitable pilot functions into long‑term infrastructure along with user‑access and support procedures. Biomedicine and public health are highlighted as areas where combining computation, data, and AI tools will support reproducible collaborative science.

The grant funds day‑to‑day operations: matching a science team’s request with distributed resources and helping them use those resources in their projects.

Semaglutide extends lifespan of old female mice by 92 days

The study, published Nature, September 2, used 79 twenty‑month‑old female mice: 40 received a daily injection of semaglutide and 39 got saline injections as a control.
Mice treated with semaglutide lived a median of 834 days, whereas controls reached 742 days, giving an advantage of 92 days. The drug also cut food intake by 24%.

Because semaglutide suppresses appetite, the lifespan gain could stem partly from reduced calorie intake rather than a direct drug effect. Gerontologist Martin Borch Jensen noted that the paper compares the drug to normal feeding but lacks a lifespan curve for mice eating the same reduced amount, asking why there is a calorie‑restriction comparison without a matched‑intake control.

In a separate five‑month cohort the authors compared semaglutide to a 24 % calorie‑restriction regimen; mice in those two groups ate the same amount and were tested for activity, memory and glucose response. The lifelong experiment described above involved daily injections for both groups, so a no‑injection control would be needed to assess any impact of the injection procedure itself.

A future lifelong study that pairs the diet, includes a no‑injection arm, and retains the semaglutide and saline groups would allow researchers to separate the contributions of the drug, reduced food intake, and the injection procedure to the observed lifespan extension. Such a design would clarify whether the lifespan increase attributed to semaglutide is a direct pharmacological effect.

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

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 added commentary.

We need to identify citations: The text mentions "Разбор, опубликованный 2 сентября 2026 года". That's a publication date. Also "В августовском разборе первых испытаний с искусственными рецепторами DREADD хемогенетика уже выглядела как переход лабораторного инструмента к пациентам". So there is a review (разбор) published August? Actually "августовском разборе" (August review). Then "Разбор, опубликованный 2 сентября 2026 года". So we have a review published September 2, 2026. Possibly the citation is the review itself. We need to wrap study/journal citations and publication references in single underscores. So we should put something like August 2026 review or Review published September 2, 2026. But we need to preserve exact citation? The text says "Разбор, опубликованный 2 сентября 2026 года". So we can put that phrase in underscores: published September 2, 2026. But we need to keep the fact exactly. Probably we should wrap the date: 2 September 2026. Also maybe the August review: August 2026 review. However we need to be selective: at most 4-5 double asterisks facts. We'll need to pick key facts: drug names (clozapine, diphenhydramine), gene names (hM4Di, GRANPA), virus (AAV), promoter (hSyn), brain regions (subthalamic nuclei, anterior cingulate cortex), disease (Parkinson's, neuropathic pain, epilepsy). Also numbers: maybe dosage? Not given. So we can pick: clozapine, diphenhydramine, hM4Di, GRANPA, AAV, hSyn, subthalamic nuclei, anterior cingulate cortex, Parkinson's, neuropathic pain, epilepsy. That's many. Need only 4-5 double asterisks. So we must select only a few key facts: maybe the drug names, the gene, the virus, the date. Let's decide: double asterisks for clozapine, diphenhydramine, hM4Di, AAV, 2 September 2026. That's 5.

We must not wrap whole sentences, just those terms.

Now single underscores for study/journal citations: we have the August review and the September 2 publication. We'll wrap those in underscores: August 2026 review and published September 2, 2026 maybe. But we need to preserve exact phrasing? The text: "В августовском разборе первых испытаний с искусственными рецепторами DREADD хемогенетика уже выглядела как переход лабораторного инструмента к пациентам". So we could wrap "августовском разборе" as August review. And "Разбор, опубликованный 2 сентября 2026 года" as published September 2, 2026. We'll keep the meaning.

Now produce headline: short, under 90 chars. Something like: "Chemogenetic neuron modulation advances toward clinical use". Count characters: Let's count: "Chemogenetic neuron modulation advances toward clinical use". That's 49 characters (including spaces). Good.

Now body: need short paragraphs 2-3 sentences each, separated by blank lines.

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

Pig Kidney Xenotransplant Keeps Patient Alive for Record 271 Days

Tim Andrews, a 66-year-old from New Hampshire, lived with a transplanted pig kidney for a record 271 days. He had end-stage renal disease caused by type 2 diabetes. Before the operation his chance of receiving a human kidney within five years was only 9%, while the risk of dying or being removed from the waitlist exceeded 40%.

The breakthrough involved deep genetic adaptation of the donor organ – a miniature Yucatan pig named Wilma. Scientists introduced 69 point changes into its genome to block endogenous pig viruses and suppress human immune rejection. Previously no xenotransplant kidney had survived longer than two months, and the first similar attempt in 2024 ended after 52 days due to heart complications.

In this case the pig kidney functioned without issues for about six months before vascular damage led to failure at the ninth month, requiring a temporary return to dialysis. No new anti‑human antibodies or pig pathogens were detected in his blood, allowing a subsequent successful transplant of a human kidney from a deceased donor.

This result first demonstrates that pig organs can serve as an effective temporary “bridge” for critically ill patients at the bottom of waiting lists. Widespread use could alleviate the global donor‑organ shortage, giving patients time to await a human transplant without the severe deterioration caused by prolonged dialysis.

First Complete Map of Male Fly Brain Reveals Full Neural Wiring

The first-ever complete map of the male fruit fly's entire brain is finally ready. It is the largest and most detailed neural blueprint in history, uniquely linking the brain and ventral nerve cord through an intact neck, allowing signals to be traced from eyes to legs.

The map enables cell‑by‑cell comparison of synaptic circuits between males and females, uncovering fundamental mechanisms of sexual dimorphism in behavior. The male CNS contains 166,700 neurons organized into 11,710 strictly identifiable cell types.

To build the model, the fly’s CNS was sliced into ultrathin layers, scanned with high‑resolution electron microscopy, and the millions of images were assembled into a 3D map using artificial intelligence and manual proof‑checking. The total human effort required for reconstruction and synapse verification equals 44 years of continuous work.

The entire dataset is now open to the global scientific community. Researchers worldwide can download and explore the connectome for further studies.

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 (e.g., Nature Aging, July 2026).

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

We need to identify citations: The text mentions "BioPharma APAC published an analysis on August 31". Also mentions "study SELECT". Also mentions "press release Sun Pharma". Also mentions "first data about candidate drug ATX-304 company Cambrian". Also mentions "SELECT" study details.

We need to wrap study/journal citations and publication references in single underscores. For example, the SELECT study is a study; we could wrap as SELECT study? Or maybe the journal? Not given. The text: "Планка видна в исследовании SELECT ." So we can wrap "SELECT" as SELECT. Also "BioPharma APAC published an analysis" - that's a publication reference? Could wrap as BioPharma APAC, August 31? The rule: wrap study/journal citations and publication references in single underscores. So we can treat "BioPharma APAC published an analysis on August 31" as a publication reference: BioPharma APAC, August 31. Also "press release Sun Pharma" maybe Sun Pharma press release. Also "first data about candidate drug ATX-304 company Cambrian" maybe Cambrian, ATX-304 data. But we need to be selective: at most 4-5 double asterisks for important facts. Single underscores for citations can be more? Not limited but we should follow.

We need to wrap key numbers, percentages, drug/company/gene names, dates in double asterisks. Choose up to 4-5.

Important facts: 17,604 participants, age >45, 39.8 months average follow-up, 6.5% vs 8.0% event rates, patent expiry March 20, price 900-2000 rupees, 750-1300 rupees, ATX-304 data from 23 participants, etc.

We need to be selective: maybe 5 double asterisks.

Let's pick: 17,604 participants, 39.8 months, 6.5% vs 8.0%, March 20 (patent expiry), 900–2,000 rupees (price). That's 5.

But also need drug names: semaglutide, tirzepatide, ATX-304, Cambrian, Sun Pharma. Should we wrap those? They are drug/company names, which are important facts. The rule says wrap key numbers, percentages, drug/company/gene names, dates in double asterisks. So we could wrap drug names as well. But we need to limit to 4-5 total. So we need to choose which to wrap. Perhaps we wrap numbers and percentages, and leave drug names not wrapped? But they said drug/company/gene names are to be wrapped. However we must be selective: at most 4-5 per post. So we need to pick the most important facts. Could wrap: semaglutide, tirzepatide, 17,604 participants, 6.5%, March 20. That's 5. Or we could wrap numbers and dates and leave drug names not wrapped, but risk missing requirement. The rule: "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". So we can choose any combination, but total <=5.

Thus we need to decide which 4-5 to wrap. Let's pick: semaglutide, tirzepatide, 17,604 participants, 6.5%, March 20. That covers drug names, key number, percentage, date.

Alternatively include price range. But we have limit.

We'll go with those.

Now we need to wrap study/journal citations in single underscores. We'll have: BioPharma APAC, August 31, SELECT study, Sun Pharma press release, Cambrian, ATX-304 data maybe.

We need to ensure we don't accidentally double wrap.

Seattle Launches AI BioDesign to Engineer Novel Proteins and Genes

On 3 September, the Allen Institute, University of Washington, and Fred Hutch Cancer Center announced the AI BioDesign program. In this initiative, AI models propose new protein and gene sequences, while laboratory experiments test them and feed results back to guide the next design round.

The partners note that evolution has explored only a fraction of possible DNA sequences over billions of years, and AI BioDesign aims to access the rest. By iterating between model suggestions and experimental measurements, the project can evaluate many variants in parallel to accelerate discovery.

For specific biological challenges, the teams plan to build tailored models. Program scientific leader David Baker, director of the Institute for Protein Design at the University of Washington, said: “For the first time, the speed of AI is matching the experimental capabilities of synthetic biology. The question shifts from ‘what has nature already made?’ to ‘what else is possible and how can we test it?’”

The Allen Institute creates large open scientific resources; the University of Washington focuses on protein design and DNA research; and Fred Hutch conducts cell and genome studies. Organizers will openly share models, datasets, lab tests, reagents, and benchmarks so other research groups can use them.

We need to identify citations: The text mentions "в статье авторы Университетской клиники Эрлангена описали один случай пациентки с БАС: после ассистированного самоубийства её тело охладили, мозг исследовали и поместили в раствор для витрификации." No explicit journal name. It says "в статье" but not which. Could be a specific article? Not given. Might need to treat as citation? The instruction: wrap study/journal citations and publication references in single underscores. If there is no explicit citation, we may not add any. However there is mention of "в статье" but no journal name; we could treat that as a citation placeholder? Probably not. We'll not add underscores unless we see something like a journal name. There's none.

Important facts: numbers: "чуть за пятьдесят" (just over fifty) -> maybe age ~50? Could be "just over 50". We'll wrap age in . Also "шесть часов после смерти охладили до 0 °C". Also "двадцать часов" (twenty hours) before autopsy. "две недели фиксировали при 4 °C". Also "−150 °C". Also "двенадцать минут после юридической смерти". Also "сентября 1" (September 1) date of article? Actually "1 сентября в статье авторы Университетской клиники Эрлангена описали один случай". So date: September 1. Also "БАС" (ALS). Also "Nectome". Also "Donation-Preservation Pathway". We need to select at most 4-5 double asterisk facts. Choose key numbers: age (~50), time to cooling (6 hours), time to autopsy (20 hours), fixation duration (2 weeks), storage temperature (-150°C), time after legal death for Nectome protocol (12 minutes). That's 6; need max 5. We'll pick maybe age, cooling time, autopsy delay, fixation time, storage temperature. Or include Nectome protocol time. Let's decide: age (~50), cooling to 0°C within 6 hours, autopsy started after 20 hours, fixation 2 weeks at 4°C, storage at -150°C. That's 5.

Wrap each in . Ensure not whole sentence.

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

We'll produce headline: maybe "German Clinic Describes Brain Preservation After Assisted Suicide in ALS Patient". Count chars: let's count: "German Clinic Describes Brain Preservation After Assisted Suicide in ALS Patient". That's about 66 characters. Good.

Now blank line.

Now body paragraphs.

We need to preserve facts exactly. Let's translate.

Paragraph 1: Introduce case: On September 1, authors from University Hospital Erlangen described a case of an ALS patient who underwent assisted suicide, then body cooled, brain examined and placed in vitrification solution.

Paragraph 2: Details: ALS is a progressive disease that robs movement and speech. Patient was just over 50. Clinic offered options: not donate brain, donate tissue for research, or structural preservation (long-term brain storage in biobank). She chose storage; told future tech might map brain structure.

Paragraph 3: Later patient prepared assisted suicide and asked if could combine with donation and preservation. Clinic had no protocol. Planned Nectome protocol requires preservation start within 12 minutes after legal death; in Erlangen they first needed to agree who receives body and who can authorize. Germany lacked legal framework for post-circulatory arrest vital organ donation. So they agreed on cornea removal, spinal cord research, and autopsy to obtain brain.…

Also cell line: U2OS. Also indicator: mKeima. Also mention of hereditary cardiomyopathy? Not needed maybe.

We need at most 4-5 double asterisk facts. Choose: September 1, CCCP, 30‑minute, six‑hour, U2OS, maybe MGRN1, MFN1, GP78, 3‑MA. But limit to 4-5. Let's pick: September 1, CCCP, 30‑minute, six‑hour, U2OS. Could also include MGRN1 as important gene. But we need selective. Perhaps we can include MGRN1 as double asterisk as it's key. But then we exceed 5. Let's decide: 5 facts: September 1, CCCP, 30‑minute, six‑hour, U2OS. That's 5. Good.

Now citations: The study published in Cell Reports on September 1. So we need to wrap that citation in single underscores: Cell Reports, September 1. Actually format: Cell Reports, September 1 (maybe include year if known). We'll just do Cell Reports, September 1.

Let's craft translation.

Paragraph 1: Introduce study: On September 1, a study was published in Cell Reports, September 1 describing a cellular model where mitochondria after brief chemical stress recovered shape and energy production. Authors found that protein MGRN1 restrained mitophagy — delivery of damaged mitochondria to lysosomes for degradation.

Paragraph 2: Explain mitophagy removes severely damaged mitochondria; in hereditary cardiomyopathy mitophagy also removes toxic protein aggregates. Authors tested intermediate case: can cell restore organelle after reversible damage? They treated lab‑grown human U2OS cells with CCCP, which rapidly disrupts mitochondrial function.

Paragraph 3: After a 30‑minute exposure and washout, mitochondria resumed normal shape within six hours; respiration, ATP production, and inner membrane cristae were restored. Recovery persisted after exposures of up to two hours, but deteriorated after four hours.

Paragraph 4: The mKeima reporter, which turns red when a mitochondrion enters a lysosome, stayed green after brief stress, whereas a mitophagy inducer (deferiprone) produced red spots. These observations, together with respiration measurements, showed functional recovery alongside morphological changes.

Paragraph 5: Researchers pre‑labeled outer‑membrane mitochondrial proteins before stress, immediately after, and after two hours of recovery. Among candidates, MGRN1 showed the strongest increase in mitochondrial association; the outer‑membrane protein MFN1 helped MGRN1 accumulate there.…

Age‑related disease burden shows increasing returns on reduction

Researchers in Nature Aging, 2 September grouped diseases by how their burden changes over life, using Global Burden of Disease data from 1990‑2023 (304 causes, 204 countries). They identified four statistical groups: infant diseases, early‑ and late‑adult diseases, and diseases whose burden rises with age.

The rising‑burden group includes ischemic heart disease, dementia, Parkinson’s, type 2 diabetes, COPD, chronic kidney disease, and some cancers. For a newborn this group accounts for the largest expected loss of healthy years across all income levels; in low‑income countries the gap versus infant diseases is tiny (about 9.05 vs 9.03 years).

Modeling constant prevalence reduction for each group, the authors’ health metric sums healthy‑life years across ages, weighting by survival probability. Lower prevalence improves health directly, and lower mortality lets more people reach older ages where benefits accrue.

For the rising‑burden group, a 50% prevalence cut yields a gain 2.2 times larger than a 25% cut; full elimination gives a gain 5.9 times larger. The other three groups show roughly linear effects, because mortality and disability occur at different ages.

Mouse cells use valine/isoleucine breakdown to export electrons under hypoxia

A preprint posted on 25 August describes how mouse cells cope with low oxygen by exporting electrons through the breakdown of valine and isoleucine. When oxygen is scarce, mitochondria struggle to pull electrons from NADH, causing NAD+ to drop and slowing energy‑yielding reactions. Cells normally offload excess electrons onto pyruvate to make lactate, but they can also convert the branched‑chain amino acids valine and isoleucine (BCAA) into keto‑acids.

Under hypoxia these keto‑acids accumulate in the cytoplasm, where the lactate dehydrogenase LDHA transfers electrons from NADH to them, forming branched‑chain hydroxyacids (BCHA) and regenerating NAD+. As the authors note in the Arc Institute analysis, “electrons still need somewhere to go, and BCAA fermentation gives them another destination.”

In mice, plasma levels of all three BCHA rose at **8% oxygen

We need to translate Russian news post into English, format: first line short headline under 90 chars, no markdown. 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. Wrap study/journal citations and publication references in single underscores (e.g., Nature Aging, July 2026). Must preserve all facts, numbers, names, citations exactly. No commentary. No source link.

We need to identify key facts: date: 1 September in Cell (the paper). Gene MMLV Gag. Numbers: 12,931 genes found in lysed cells; 11,598 also in medium; correlation coefficient 0.797. Four-day differentiation: 772 genes with changed activity. Microfluidic: seven days, six devices, would need 42 independent if destructive. Also mention control: shortened Gag gave less RNA.

We need to limit double asterisks to at most 4-5 facts. Choose maybe: 1 September, Cell, MMLV Gag, 12,931 genes, 11,598 genes, 0.797 correlation, 772 genes, six devices, 42 independent. That's many; need only 4-5. So select most important: date, journal, gene name, correlation coefficient, number of genes changed in differentiation, maybe number of devices vs destructive. But we need to keep facts but can't overdo double asterisks. We can embed some numbers without double asterisks? The rule: 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 must choose which facts to bold. Others remain plain text but still must be preserved. So we need to include all facts but only some get double asterisks. Choose maybe: 1 September, Cell, MMLV Gag, 0.797, 772 genes. That's 5. Could also include six devices but then exceed. We'll stick with those five.

Now need to wrap study/journal citations in single underscores. The citation is the paper: "в Cell вышла работа". So we need Cell maybe with date? The format: Nature Aging, July 2026. So we should put Cell, September 1? Actually the paper published 1 September in Cell. So we can put Cell, September 1. That satisfies citation.

On July 3, Minister Rianne Letsche rt wrote to parliament that the Biomedical Primate Research Centre (BPRC) can again allocate its institutional grant based on scientific need, after the House of Representatives reversed the earlier plan in March and the Senate confirmed the reversal on June 30. The previous plan would have directed the entire institutional subsidy to animal‑free methods by 2030, making long‑term project planning difficult for the centre.

Now BPRC must distribute the grant weighing scientific need and the availability of suitable animal‑free methods; the government has limited primate experiments to 120–150 per year and requires the share of the institutional grant for developing and validating animal‑free methods to increase from 17% to 30% by 2030.

BPRC houses about 1,000 macaques and is one of only two EU organisations with its own primate breeding colony; the ministry ties the centre’s work to infection, brain disease, and drug research, and obliges BPRC to collaborate with developers of animal‑free methods and share data with them.

On September 2, The Transmitter reported that parliament will revisit animal‑research funding this autumn and may propose budget changes; centre director Merel Langeleer said BPRC is now fully dependent on policy and elections, and the government plans an independent evaluation of further reductions in primate experiments by 2030.

China proposes national dual-use research risk management system

On 31 August, the journal Frontiers in Bioengineering and Biotechnology published a review by Ruihan Zhang. The author proposes a national system for managing risks of dual‑use life‑science research. Dual‑use research is legitimate work whose results could be misused for harm.

Zhang divides risk into five pathways and allocates eleven measures across three stages of implementation. The pathways begin with different triggering events, such as a laboratory accident, insider misuse, cyberattack, work outside conventional institutions, and publications that facilitate dangerous application.

The first stage includes a general regulatory framework, project evaluation by scientific organisations, and epidemiological surveillance of unusual health events. These measures split responsibility between research institutions and the health system.

At the second stage, laboratories introduce daily risk management, response plans, protection for medical and lab staff, access‑misuse controls, and outreach to the public.

The third stage covers protection of digital systems, rules for responsible publication, and international exchange of experience. This structure shows who evaluates projects, who detects anomalous cases, and who answers when risk extends beyond the lab walls.

Separately, Zhang incorporates physicians, laboratory personnel, and response services into the system, stressing that safety depends on the people who first encounter a threat and on the coordination of their actions.

Tabula Sapiens 2.0 Atlas Maps 1.1 Million Cells Across 28 Tissues

On September 2, the journal Cell, September 2 published an article describing the second version of the Tabula Sapiens atlas, which now includes data from 1.1 million cells across 28 human tissues. The update added nine donors and four tissues, and examined RNA profiles of cells that have stopped dividing.

RNA molecules are working copies of genes, showing which genes a cell is currently reading. Because comparing organs across individuals can mix tissue differences with donor‑specific variation and sample handling, the researchers took multiple organs from four of the nine new donors to isolate tissue effects.

To study stable cell‑division arrest (senescence), they defined a working condition: a cell must contain RNA of CDKN2A (a cell‑cycle‑arrest gene) and lack RNA of MKI67 (a marker of active division). Using this criterion they isolated 48,114 cells from 25 tissues of 21 donors.

We need to preserve facts: Tabula Sapiens 2.0 collected atlas of 1.1 million cells from 28 human tissues. On September 2, article about second version of Tabula Sapiens published in journal Cell. They added nine donors and four tissues, and studied RNA profiles of cells with division arrest. RNA are working copies of genes: they show which genes a cell is currently reading. Inter-organ comparisons easily mix tissue properties with differences between individuals and sample processing. Therefore, for four of the nine new donors they took multiple organs. Comparing tissues from same person allows researchers to more clearly separate tissue contribution from donor-related differences. For analysis of senescence — stable cell division arrest — authors set working condition: cell has RNA copy of gene CDKN2A, associated with cell cycle arrest, and lacks RNA copy of MKI67, indicator of active division. Thus they isolated 48,114 cells from 25 tissues of 21 donors. For each combination of cell type, tissue, and donor, their RNA compared with other cells of same group. In this sample they found 3,792 genes with elevated RNA levels. After CDKN2A, the most common was CDKN2B, also related to cell cycle arrest: it increased in 18 of 30 major cell groups. CXCL8 and MIF increased in five such groups, SERPINE1 — in two. Then authors combined these genes into 17 programs — groups of genes whose RNA levels change together. In epithelial cells forming organ coverings and linings, and fibroblasts creating tissue support, adhesion programs are more noticeable. In immune, epithelial, and stem cells, energy exchange programs and systems that assemble and disassemble proteins changed differently. The working criterion gathered the overall sample, and its RNA programs primarily differed together with cell type.

We need to select key facts for double asterisks: numbers: 1.1 million cells, 28 tissues, September 2, Cell journal, nine donors, four tissues, 48,114 cells, 25 tissues, 21 donors, 3,792 genes, CDKN2A, CDKN2B, CXCL8, MIF, SERPINE1, 18 of 30 major cell groups, five groups, two groups, 17 programs. That's many. We need at most 4-5 double asterisks. So we need to be selective: maybe highlight total cells, date, journal, number of donors/tissues added, number of senescent cells isolated, number of elevated genes, maybe top gene. Choose 4-5.

We need to wrap study/journal citations in single underscores: e.g., Cell, September 2 or Cell? The citation: article published in Cell on September 2. So we can put Cell, September 2.

Now produce headline: maybe "Tabula Sapiens 2.0 Atlas Maps 1.1 Million Cells Across 28 Human Tissues".

Bacterial Patterns Shift with Moving Frog Embryon and Xenobot, Machine Model Distinguishes Conditions

On September 3, a preprint reported that motile *Bacillus subtilis* bacteria altered their pattern in fluid near a frog embryo and a xenobot — a body assembled from embryonic cells. When the embryo was moved, the bacterial accumulation zone moved with it. The bacterial pattern allowed a computer model to distinguish three conditions: embryo, xenobot, and bacteria‑only culture.

Researchers tested whether the bacterial spatial pattern contains information about a neighboring living system, comparing the frog embryo and xenobot (both share the same species and genome, but the xenobot is assembled separately and develops differently). In bacteria‑only culture, motile cells self‑organized into a branching pattern; a non‑motile strain and fluorescent microparticles hardly produced this pattern. Near the xenobot, motile bacteria formed a glowing halo whose average area reached 9.4 mm² after one hour, while in the two control groups it remained at hundredths of a square millimeter. This linked the halo to active bacterial behavior.

Near the living embryo the halo grew; near a heat‑inactivated embryo the early accumulation then receded. When the embryo was translocated, the bacterial cluster disappeared from the original site and appeared at the new location, showing that the bacterial pattern changes with the target’s position and state.

Researchers then examined the ionic environment. Raising potassium chloride concentration from 1.5 to 200 mmol/L increased the halo area to 23.0 mm² by the 11th hour, up from 0.67 mm² at baseline. Bacteria lacking the YugO potassium‑channel protein showed slower early accumulation, indicating that the ionic milieu modulates the early bacterial response to the living target.

To force the model to rely on the bacterial pattern, the target’s silhouette was masked in the frames. From the remaining bacterial distribution on deposited rollers the model distinguished the three conditions with 61.13% accuracy, compared with a baseline of 33%. The authors conclude that “the physiological state of one collective is partially recorded in the shape of another,” showing that bacterial positioning serves as a measurable readout of the state and position of a neighboring multicellular target.

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

First line: short headline under 90 chars, no markdown. 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, citations exactly. No added commentary.

We need to identify important facts: numbers like 186, 70 million, 4680, 600, 246, 40 fixed additions, 77 rational coefficients, >1/50000 margin, August 2025? Actually date: "30 августа OpenAI опубликовала работу" => August 30 (year unspecified, likely 2025?). The original text: "OpenAI опубликовала результат GPT-6 Astra: бесконечно многие соседние простые различаются не более чем на 186 30 августа OpenAI опубликовала работу о коротких промежутках между простыми." So date: August 30 (maybe 2024?). We'll keep as "August 30". Also mention "2013 year Ethan Zhang", "Polymath projects", "James Maynard", "next Polymath project", "OpenAI work reduces bound to 186". Also mention "Axiom Math formalized previous bound 246 in August". Also mention "Lean 4 code", "numerical certificate", "Selberg sieve", etc.

We need to wrap key numbers in double asterisks: maybe 186, 70 million, 4680, 600, 246, 40, 77, >1/50000. That's many; we need at most 4-5. So we must be selective: choose the most important: the bound 186, the previous bound 246, the improvement from 70 million to 186 maybe mention 70 million as historical. But we can only have 4-5 total. Let's pick: 186, 246, 70 million, 40 (fixed additions), maybe 77 rational coefficients. That's 5.

We must not wrap whole sentences; just wrap the numbers.

Citations: we have references to work by OpenAI, Polymath, James Maynard, Axiom Math formalization, Lean checking. We need to wrap study/journal citations and publication references in single underscores. There's no explicit journal name; maybe we treat the work as a paper? Could use OpenAI work, August 30? But that's not a journal. The instruction: "Wrap study/journal citations and publication references in single underscores (e.g. Nature Aging, July 2026)." So we need to identify any such citations. The text mentions "OpenAI опубликовала работу", "В августе Axiom Math формализовала прежнюю границу 246 ; там Lean проверял цепочку уже известной теоремы." Also "В новом репозитории эта цепочка начинается с трёх явно названных входов". Not exactly journal citations. Could treat "OpenAI work, August 30" as a publication reference. Also "Axiom Math, August". We'll wrap those in single underscores.

We must not add source link.

Now produce headline: maybe "OpenAI’s GPT-6 Astra proves infinitely many prime gaps ≤ 186". Count characters: Let's count: "OpenAI’s GPT-6 Astra proves infinitely many prime gaps ≤ 186". That's about 58 characters. Good.

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

We'll produce maybe 4 paragraphs.

Paragraph 1: Summarize the result: On August 30, OpenAI released a result from GPT-6 Astra showing that infinitely many consecutive primes differ by at most 186, i.e., lim inf (p_{n+1} - p_n) ≤ 186. Include citation OpenAI work, August 30.…

We'll wrap Axiom Math in single underscores.

Also maybe "Lean 4" is a tool, not citation. Not needed.

We need to preserve all facts exactly. So we need to translate the content.

Let's draft headline: "OpenAI’s GPT-6 Astra proves infinitely many prime gaps ≤ 186". Count characters: Let's count: "OpenAI’s GPT-6 Astra proves infinitely many prime gaps ≤ 186". That's about 58 characters. Good.

Now body paragraphs.

We need to split into short paragraphs 2-3 sentences each.

We'll produce maybe 4 paragraphs.

Paragraph 1: On August 30, OpenAI released a result from GPT-6 Astra showing that infinitely many adjacent primes differ by no more than 186. The proof was produced by GPT-6 Astra, accompanied by a numerical certificate and Lean 4 code that checks the logical steps.

Paragraph 2: The number 186 means that there are infinitely many pairs of consecutive primes with a gap at most 186; formally, lim inf (p_{n+1} − p_n) ≤ 186. In 2013, Yitang Zhang established an upper bound of 70 million; subsequent Polymath projects reduced it to 4680, James Maynard to 600, and another Polymath effort to 246. OpenAI’s work improves this bound to 186.

Paragraph 3: The authors select 40 fixed shifts added to a base integer n, all lying between 0 and 186, and prove that for infinitely many n at least two of the shifted numbers are prime, giving a gap ≤ 186. The proof uses a multidimensional Selberg sieve, assigning numerical weights to such sets and estimating prime frequency. A new technique factors common divisors into three parts of suitable size, allowing a broader weight set and the needed inequality for the 40 numbers.…
