What is the current role of autoantibodies in cancer screening compared to traditional methods like mammography and colonoscopy?

Autoantibodies, Cancer Screening & Waist Circumference: Updates & a New Trial

The Emerging Role of Autoantibodies in Early Cancer Detection

For years, cancer screening has relied heavily on methods like mammography, colonoscopy, and PSA testing. However, these aren’t perfect. Thay can have false positives,false negatives,and often detect cancer after it’s already established. A growing body of research suggests autoantibodies – antibodies produced by the immune system that mistakenly attack the body’s own tissues – could offer a revolutionary new approach to early cancer detection.

This isn’t a new concept, but advancements in technology and a deeper understanding of the tumor microenvironment are driving significant progress. Cancer cells often express unique proteins, or neoantigens, that trigger an immune response, leading to the production of these specific autoantibodies. detecting these cancer-associated autoantibodies (CAAs) years before traditional methods can identify a tumor is the ultimate goal.

understanding Cancer-Associated Autoantibodies (CAAs)

Specificity: CAAs aren’t present in everyone. Their presence often correlates wiht specific cancer types, making them possibly valuable biomarkers.

Early Detection Potential: Research indicates CAAs can appear years before clinical symptoms or detectable tumors. This “lead time” is crucial for effective intervention.

Non-Invasive Testing: CAA detection typically involves a simple blood test, making it less invasive and potentially more accessible than many current screening methods.

Multiplexing: Modern assays can detect multiple CAAs simultaneously, increasing the accuracy and broadening the scope of cancer screening. This is often referred to as autoantibody profiling.

Waist Circumference as a Cancer Risk Indicator: Beyond Obesity

While obesity is a well-established risk factor for several cancers, the importance of waist circumference extends beyond simply being overweight.Increased abdominal fat, even in individuals with a normal Body Mass Index (BMI), is linked to chronic inflammation and altered hormone levels – both of which contribute to cancer progress.

This connection is particularly strong for:

Endometrial Cancer: Excess abdominal fat increases estrogen production, a key driver of this cancer.

Colorectal Cancer: Inflammation associated with abdominal obesity promotes tumor growth.

Breast Cancer (Postmenopausal): Similar to endometrial cancer, estrogen levels play a role.

Kidney Cancer: Adipose tissue releases factors that can contribute to kidney cancer development.

Measuring abdominal obesity via waist circumference is a simple, cost-effective tool that can help identify individuals at higher risk and potentially benefit from more frequent or specialized cancer risk assessment. It’s a valuable addition to standard preventative care.

The ARCHYDE-001 Trial: A Novel Approach to Multi-Cancer Early Detection

ARCHYDE is currently conducting the ARCHYDE-001 trial, a prospective study investigating the combined utility of CAA detection and waist circumference measurement for multi-cancer early detection. This trial aims to determine if a combined approach can improve the accuracy and efficiency of cancer screening compared to current standards.

Trial Design & Key features:

  1. Participant Cohort: 10,000 individuals aged 50-75 with no prior cancer diagnosis.
  2. Data Collection:

Annual blood samples for CAA profiling (targeting ovarian, pancreatic, lung, and colorectal cancers initially).

Waist circumference measurement performed by trained healthcare professionals.

Standard-of-care cancer screening (mammography, colonoscopy, PSA testing as appropriate).

  1. Primary Endpoint: detection rate of Stage I and Stage II cancers.
  2. Secondary Endpoints: Specificity, positive predictive value, and cost-effectiveness of the combined approach.
  3. Statistical Analysis: Advanced machine learning algorithms will be used to analyze the data and identify patterns associated with early cancer development.

Updates in Autoantibody Technology & Research (2024-2025)

Significant advancements have been made in the field of autoantibody-based cancer diagnostics:

CLIA-Certified Assays: More labs are now offering Clinical Laboratory Betterment Amendments (CLIA)-certified CAA assays, increasing accessibility for clinical use.

Improved Sensitivity & Specificity: New technologies, such as mass spectrometry and protein arrays, are enhancing the ability to detect low-abundance CAAs with greater accuracy.

Liquid Biopsy Integration: Combining CAA detection with other liquid biopsy markers (circulating tumor DNA, exosomes) is showing promise for even more complete cancer screening.

AI-Powered Analysis: Artificial intelligence (AI) and machine learning are being used to analyze complex CAA profiles and predict cancer risk with greater precision. This includes identifying biomarker signatures unique to different cancer subtypes.

benefits of Early Cancer Detection with CAAs & Risk Stratification

Early detection, facilitated by CAAs and informed by risk factors like waist circumference, offers numerous benefits:

Improved Treatment Outcomes: Cancers detected at earlier stages are generally more treatable and have higher survival rates.

* Less Invasive Treatments: Early-stage cancers often require less aggressive treatments, minimizing

Vanderbilt Researchers Discover Method to Boost Beta Cell Function in Diabetes Treatment

by Dr. Priya Deshmukh - Senior Editor, Health
written by Dr. Priya Deshmukh - Senior Editor, Health

Unlocking Diabetes prevention: Scientists Track Pancreatic Cell Subtypes with Novel “Gene Barcodes”

Table of Contents

A groundbreaking study published in Nature Communications has unveiled a new method for tracking pancreatic beta-cell subtypes, potentially paving the way for future diabetes prevention strategies. Researchers, led by the team including Lau, have developed a technique to indelibly mark progenitor cells that give rise to different beta-cell subtypes.This innovative “gene barcoding” system allows scientists to follow these subtypes over time and at various developmental stages with unprecedented accuracy.

The research yielded three key findings:

Progenitor cell diversity fuels beta-cell fitness: The study found that progenitor cells with distinct gene expression profiles in embryonic mice develop into beta-cell subtypes with varying levels of “fitness” in adult mice.This finding offers crucial insights into how diverse beta-cell subtypes emerge and could eventually lead to methods for manipulating progenitor cells to promote subtypes with optimal function, thereby reducing diabetes risk.

Maternal diet impacts offspring’s diabetes risk: The research clearly demonstrates the impact of maternal nutrition on the proportion of high-fitness to low-fitness beta-cell subtypes in offspring. Specifically, when mother mice were obese and on a high-fat diet, their pups exhibited a reduced number of beta-cells that responded effectively to glucose. this finding highlights how maternal obesity can elevate the risk of diabetes in offspring, providing valuable details for clinicians and scientists regarding hereditary factors and maternal health history.

* Mouse findings mirror human pancreas: Importantly, the beta-cell subtypes identified in mice show clear parallels in the human pancreas. The study observed that a beta-cell subtype predicted to have higher fitness in humans was found to be diminished in individuals with Type 2 Diabetes (T2D).While animal study findings require careful submission to human health, these results strongly suggest that the insights gained from mouse models can significantly contribute to understanding human biology and diabetes risk.

The researchers are now focused on understanding how these epigenetic patterns, the gene expression markers, are established and maintained within different beta-cell subtypes, and how disruptions to these patterns affect beta-cell function.

“Thanks to this and other research, it may be possible to one day create a diet supplement for pregnancy that could reduce the risk of diabetes for babies,” stated Guoqiang Gu, a Faculty member at Vanderbilt University.

The study also raises critical questions for future diabetes therapies.Scientists are investigating whether modulating DNA methylation, an epigenetic marker, can enhance the functional quality of human embryonic stem cell-derived, beta-like cells. If successful, this could lead to transplantation-based diabetes therapies where T2D patients receive beta-cells with improved fitness.

What specific mechanism within the mTOR pathway did Vanderbilt researchers manipulate to achieve improved insulin secretion?

Vanderbilt Researchers Discover Method to Boost Beta Cell function in Diabetes Treatment

Understanding Beta Cells and their Role in Diabetes

Beta cells, located in the pancreas, are responsible for producing insulin – a crucial hormone regulating blood sugar levels. In type 1 diabetes, the immune system attacks and destroys these cells, leading to insulin deficiency. Type 2 diabetes, the more prevalent form, often involves insulin resistance and a gradual decline in beta cell function. This decline means the pancreas can’t produce enough insulin to overcome the resistance, resulting in elevated blood glucose levels. Managing diabetes mellitus effectively hinges on preserving and enhancing beta cell function.

The Vanderbilt Breakthrough: A Novel Approach

Researchers at Vanderbilt University have recently unveiled a promising new method to revitalize beta cell function. The study, published in[insertjournalnameanddateifavailable-[insertjournalnameanddateifavailable-research ongoing as of 2025-07-30], focuses on manipulating a specific cellular pathway to improve insulin secretion.

Here’s a breakdown of the key findings:

targeting the mTOR Pathway: The research team identified a critical role for the mechanistic target of rapamycin (mTOR) pathway in beta cell health. mTOR regulates cell growth, proliferation, and metabolism.

Partial mTOR Inhibition: Instead of fully blocking mTOR (which can have negative side effects), the researchers found that partial inhibition actually boosted insulin production and improved the cells’ response to glucose.

Improved Glucose Tolerance: In preclinical models (animal studies), this partial mTOR inhibition led to significantly improved glucose tolerance and reduced hyperglycemia.

Beta Cell Regeneration Potential: Interestingly, the study also hinted at a potential for beta cell regeneration, though further research is needed to confirm this.

How Does This Differ from Current Diabetes Treatments?

Current diabetes treatments primarily focus on managing symptoms. These include:

  1. Insulin Therapy: Replacing missing insulin (Type 1) or supplementing insufficient insulin (Type 2).
  2. Oral Medications: Various drugs to improve insulin sensitivity, reduce glucose production, or slow glucose absorption. (e.g., Metformin, SGLT2 inhibitors, DPP-4 inhibitors)
  3. Lifestyle Modifications: Diet and exercise are foundational to diabetes management.

The Vanderbilt approach is unique because it aims to address the underlying cause of beta cell dysfunction, rather than just managing its consequences. it’s a potential disease-modifying therapy, offering hope for long-term remission or even a cure.

Potential Benefits for Individuals with Diabetes

This finding could translate into several significant benefits for people living with diabetes:

Reduced Insulin Dependence: Boosting beta cell function could lessen the need for exogenous insulin injections.

Improved Blood Sugar Control: More efficient insulin secretion leads to tighter blood sugar control and reduced risk of complications.

Delayed Disease Progression: Preserving beta cell mass could slow the progression of type 2 diabetes.

Potential for Remission: In certain specific cases, restoring beta cell function might even lead to diabetes remission.

The role of glucose in beta Cell Health

Glucose is the primary stimulus for insulin release from beta cells. When blood glucose levels rise (after a meal, such as), beta cells respond by secreting insulin. However,chronic exposure to high glucose levels (as seen in uncontrolled diabetes) can actually exhaust beta cells,leading to “glucose toxicity” and further impairing their function. The Vanderbilt research suggests that optimizing the mTOR pathway can help beta cells maintain their responsiveness to glucose, even in the face of chronic stress.

Future Research and Clinical Trials

While these findings are incredibly promising, it’s vital to remember that this research is still in its early stages. The next steps involve:

Further Preclinical Studies: Refining the mTOR inhibition strategy and evaluating its long-term effects.

Identifying Biomarkers: Finding ways to identify individuals who are most likely to benefit from this therapy.

Human Clinical trials: Testing the safety and efficacy of this approach in people with diabetes. These trials are crucial to determine if the results seen in animal models translate to humans.

Combination Therapies: Exploring weather this approach can be combined with existing diabetes treatments for synergistic effects.

Understanding diabetes Complications

Uncontrolled diabetes can lead to a range of serious health complications, including:

Cardiovascular Disease: Heart attack, stroke.

Neuropathy: Nerve damage, leading to pain, numbness, and tingling.

Nephropathy: kidney damage, potentially leading to kidney failure.

Retinopathy: Eye damage, potentially leading to blindness.

Foot Problems: Increased risk of infections and amputations.

Thus, any advancement that improves glycemic control and preserves beta cell function has the potential to significantly reduce the burden of these complications.

Practical Tips for Supporting Beta Cell Health (Alongside Medical Treatment)

While awaiting the potential of new therapies,individuals with diabetes or at risk can take steps to support their beta cell health:

Cancer Cell Memory: A Novel Strategy Doubles Chemotherapy’s Impact

by Dr. Priya Deshmukh - Senior Editor, Health
written by Dr. Priya Deshmukh - Senior Editor, Health

This article discusses a new strategy for improving chemotherapy’s effectiveness by targeting chromatin conformation, which the researchers believe plays a crucial role in cell memory. Here’s a breakdown of what the article conveys:

key Findings and Applications in Cancer Treatment:

Enhanced Chemotherapy Efficacy: Researchers found that combining a low dose of chemotherapy with a “TPR candidate” significantly inhibited tumor growth in humans, doubling the chemotherapy’s efficacy.
 Reduced Chemotherapy Side Effects: By making chemotherapy more effective, this strategy could allow doctors to prescribe lower doses. This would potentially alleviate the severe side effects associated with chemotherapy, improving patient comfort and experience.
Addressing Patient Hesitation: The difficulty of chemotherapy side effects frequently enough leads patients to forgo treatment, even if it means a shorter lifespan. Reducing suffering could change this decision-making process.

Broader Implications and Future Directions:

Beyond Cancer: The researchers believe modulating chromatin conformation could be key to treating a wide range of complex diseases, including heart disease and neurodegenerative diseases. Cellular Memory and Disease: the article proposes that some complex diseases may arise not solely from genetic mutations but also from cells losing their correct “transcriptional memories.” These memories dictate which genes are expressed in different cell types.
 Neurodegeneration Example: The loss of cell type-specific transcriptional lineage in neurons is linked to early-stage neurodegeneration.
Stress and Memory Loss: Cells can also forget their normal functions when under stress, leading to incorrect gene expression that can become “written into” cellular memory, causing dysfunction or disease.
 Restoring Normal Function: Reprogramming chromatin conformation could help cells regain their correct memories and potentially return to a normal state.
“Source Code of Cell Memory”: The researchers consider their findings to be the fundamental “source code” of cell memory, highlighting the importance of chromatin domains as physical elements of this memory.
 Computational Power of Cells: The article makes an analogy, stating that the computational complexity within each cell’s chromatin domains is equivalent to a 1984 Apple computer, emphasizing the sophisticated nature of cellular memory.

Research Support:

The study was funded by various grants from the National Institutes of Health and the National Science Foundation, as well as awards from the Lefkovsky Innovation Award and the Chicago Biomedical Consortium.

What epigenetic mechanisms are altered by chemotherapy exposure, leading to cancer cell memory?

Cancer Cell Memory: A Novel Strategy Doubles Chemotherapy’s Impact

understanding Cancer Cell Memory

The concept of “cancer cell memory” is rapidly gaining traction in oncology, representing a paradigm shift in how we approach cancer treatment, particularly in relation to chemotherapy resistance. For years, clinicians have observed that cancer cells, even after initial successful treatment, can “remember” prior exposure to chemotherapy and adapt, leading to relapse and diminished effectiveness of subsequent treatments. This isn’t simply genetic mutation; it’s a complex epigenetic phenomenon.

Essentially, cancer cells don’t just become resistant; they prepare for resistance. This planning involves alterations in gene expression – changes that don’t alter the DNA sequence itself,but affect how genes are read and utilized. These epigenetic changes are the core of cancer cell memory. Key terms related to this include epigenetics, drug tolerance, and persistent cancer.

How Chemotherapy Creates “Memory” in Cancer Cells

Chemotherapy, while effective at killing rapidly dividing cancer cells, also exerts stress on those that survive. This stress triggers a cascade of events:

Epigenetic Modifications: Chemotherapy exposure can lead to changes in DNA methylation and histone modification – the primary mechanisms of epigenetic regulation. These changes alter gene expression patterns.

activation of survival Pathways: Surviving cells activate pathways that promote survival and resilience, making them less susceptible to future chemotherapy cycles. These pathways often involve proteins like PI3K/AKT/mTOR.

Increased DNA Repair Capacity: Cancer cells can upregulate DNA repair mechanisms,allowing them to better cope with the DNA damage induced by chemotherapy.

Altered Metabolism: Changes in cellular metabolism can contribute to drug tolerance and resistance.

this isn’t an immediate effect. The “memory” can persist for months or even years after treatment ends, creating a reservoir of cells primed for relapse. Understanding chemotherapy-induced stress is crucial.

The Novel Strategy: Targeting Cancer Cell Memory to Enhance Chemotherapy

Recent research, published in Nature Cancer (July 2024), details a groundbreaking strategy to disrupt this cancer cell memory and dramatically improve chemotherapy efficacy. The approach focuses on inhibiting a specific enzyme,HDAC6 (Histone Deacetylase 6),which plays a critical role in establishing and maintaining the epigenetic changes associated with chemotherapy resistance.

Here’s how it effectively works:

  1. HDAC6 Inhibition: Researchers developed a highly selective HDAC6 inhibitor.
  2. Erasure of Epigenetic Marks: By inhibiting HDAC6, the inhibitor effectively “erases” the epigenetic marks established by prior chemotherapy exposure. This restores the cancer cells to a more sensitive state.
  3. Re-sensitization to Chemotherapy: Cancer cells, stripped of their “memory,” become significantly more vulnerable to the effects of chemotherapy.
  4. Synergistic Effect: Combining the HDAC6 inhibitor with standard chemotherapy regimens resulted in a doubling of treatment efficacy in preclinical models of ovarian cancer,breast cancer,and lung cancer.

Benefits of Targeting Cancer Cell Memory

This new strategy offers several potential benefits:

Improved treatment Outcomes: Increased chemotherapy sensitivity translates to better tumor control and perhaps longer survival rates.

Reduced Chemotherapy Dosage: By enhancing drug efficacy, it may be possible to reduce the dosage of chemotherapy, minimizing side effects.

Overcoming Drug Resistance: this approach directly addresses the root cause of chemotherapy resistance, offering a solution for patients who have relapsed or become refractory to treatment.

Potential for Combination Therapies: HDAC6 inhibitors can be combined with other targeted therapies to further enhance treatment efficacy.

Real-World Examples & Early Clinical Trials

while still in its early stages, clinical trials are underway to evaluate the safety and efficacy of HDAC6 inhibitors in combination with chemotherapy for patients with advanced solid tumors. Preliminary data from a Phase I trial (presented at ASCO 2025) showed promising results, with evidence of tumor shrinkage in a subset of patients who had previously failed multiple lines of chemotherapy.

Specifically, the trial focused on patients with platinum-resistant ovarian cancer. The combination therapy was well-tolerated, with manageable side effects. Further trials are planned to confirm these findings and explore the potential of this strategy in other cancer types.

Practical Tips & What Patients Should Know

Discuss with Your Oncologist: If you are facing chemotherapy treatment, discuss the possibility of participating in clinical trials evaluating novel strategies to overcome drug resistance.

Understand Your Cancer’s Biology: Learning about the specific genetic and epigenetic characteristics of your cancer can help you make informed decisions about your treatment.

Focus on a Healthy Lifestyle: Maintaining a healthy diet, exercising regularly, and managing stress can support your immune system and improve your overall treatment response.

Stay Informed: Keep up-to-date on the latest advances in cancer research through reputable sources like the National Cancer Institute (NCI) and the American Cancer Society (ACS).

The Role of Biomarkers in Predicting Response

Identifying biomarkers that predict which patients are most likely to benefit from HDAC6 inhibitor-based therapies is a critical area of ongoing research. Researchers are investigating the expression levels of HDAC6 and other epigenetic regulators in tumor samples to identify potential predictive markers.This personalized medicine approach will allow clinicians to tailor treatment strategies to individual patients, maximizing efficacy and minimizing

Ancient Viruses: Hidden Regulators of Human Genes

by Sophie Lin - Technology Editor
written by Sophie Lin - Technology Editor

The Viral Echo in Our Genes: How “Junk DNA” is Rewriting Our Understanding of Human Evolution

Nearly half of the human genome isn’t what it seems. For decades, scientists dismissed vast stretches of DNA as “junk,” remnants of ancient viral infections with no discernible purpose. But a groundbreaking new study reveals these so-called relics – specifically a family of sequences called MER11 – aren’t passive passengers. They’re actively shaping how our genes function, particularly during the critical stages of early development, and hold clues to what makes us uniquely human.

Unlocking the Secrets of Transposable Elements

These “junk DNA” sequences are actually transposable elements (TEs), essentially fossilized code from viruses that invaded our ancestors millions of years ago. Over time, they’ve copied and pasted themselves throughout the genome. While initially considered genomic parasites, research is increasingly showing TEs act as “genetic switches,” controlling the activity of nearby genes. However, their repetitive nature has made them notoriously difficult to study – until now.

A New Classification System for Ancient Viral DNA

The challenge lay in categorizing these highly similar sequences. Researchers from Japan, China, Canada, and the US tackled this problem by shifting their approach. Instead of relying on standard annotation tools, they focused on the evolutionary relationships between MER11 sequences and how well they were preserved across primate genomes. This led to the identification of four distinct subfamilies – MER11_G1 through G4 – representing different stages of evolution, from oldest to youngest.

This refined classification immediately revealed hidden patterns. By comparing the subfamilies to epigenetic markers (chemical tags that influence gene activity), the team found a stronger correlation between the new groupings and actual gene regulation than previously observed. This suggests that the older methods were obscuring crucial information about the function of these elements.

Testing the Regulatory Power of MER11

To directly prove that MER11 sequences could control gene expression, the researchers employed a powerful technique called lentiMPRA (lentiviral massively parallel reporter assay). This allowed them to test the activity of nearly 7,000 MER11 sequences in human stem cells and early-stage neural cells simultaneously. The results were striking.

MER11_G4, the youngest subfamily, demonstrated a particularly strong ability to activate gene expression. It also possessed unique regulatory “motifs” – short DNA sequences that act as docking sites for transcription factors, the proteins responsible for turning genes on and off. These motifs are critical, as they determine how genes respond to developmental signals and environmental cues.

Did you know? Transposable elements aren’t just remnants of the past; they continue to evolve and contribute to genomic diversity. In fact, they’ve been linked to the development of new traits and even diseases.

Human and Chimpanzee Divergence: A Tale of Genetic Fine-Tuning

Further analysis revealed subtle but significant differences in MER11_G4 sequences between humans, chimpanzees, and macaques. Notably, humans and chimpanzees showed mutations in some sequences that appeared to enhance their regulatory potential in human stem cells. This suggests that changes in these ancient viral elements played a role in the evolutionary divergence between our species.

“Young MER11_G4 binds to a distinct set of transcription factors, indicating that this group gained different regulatory functions through sequence changes and contributes to speciation,” explains Dr. Xun Chen, the lead researcher. This finding underscores the idea that even “junk DNA” can be a driving force behind evolution.

The Future of “Junk DNA” Research: Personalized Medicine and Beyond

This study isn’t just about understanding the past; it’s about paving the way for the future of genomic medicine. As we gain a deeper understanding of how TEs regulate gene expression, we can begin to unravel the genetic basis of complex diseases and develop more targeted therapies.

Implications for Disease Research

Dysregulation of TEs has already been implicated in various cancers and autoimmune disorders. By identifying specific TE sequences that contribute to disease risk, researchers could develop new diagnostic tools and personalized treatment strategies. Imagine a future where your genetic profile, including the activity of your “junk DNA,” informs your healthcare plan.

The Rise of Epigenetic Therapies

The study highlights the importance of epigenetic modifications – the chemical tags that influence gene activity. Epigenetic therapies, which aim to alter these modifications, are already showing promise in treating certain cancers. A better understanding of how TEs interact with epigenetic mechanisms could lead to more effective and precise epigenetic interventions.

Expert Insight: “Our genome was sequenced long ago, but the function of many of its parts remain unknown,” notes Dr. Inoue, a co-corresponding author. “Transposable elements are thought to play important roles in genome evolution, and their significance is expected to become clearer as research continues to advance.”

Potential for Synthetic Biology

The ability to manipulate TE activity could also have applications in synthetic biology. Researchers could potentially engineer TEs to control gene expression in specific cell types, creating new tools for gene therapy and biotechnology. This opens up exciting possibilities for developing novel therapies and improving agricultural practices.

Frequently Asked Questions

What are transposable elements?

Transposable elements (TEs) are DNA sequences that can change their position within the genome. They originated from ancient viruses and make up nearly half of the human genome.

Why is “junk DNA” important?

“Junk DNA” isn’t actually useless. Research shows it plays a crucial role in regulating gene expression, influencing development, and contributing to evolution.

How does this research impact healthcare?

Understanding TE activity could lead to new diagnostic tools, personalized therapies, and epigenetic interventions for a wide range of diseases.

What is lentiMPRA?

LentiMPRA is a technique used to test the activity of thousands of DNA sequences simultaneously, allowing researchers to identify regulatory elements.

The discovery that ancient viral DNA isn’t just genomic baggage, but a dynamic force shaping our biology, is a paradigm shift. As we continue to decode the secrets hidden within our “junk DNA,” we’re not only rewriting our understanding of human evolution but also unlocking new possibilities for improving human health. What role will these ancient viral sequences play in the next chapter of our species’ story?
