Knowledge check
Q1. Which term is generally credited with popularizing the concept of 'biohacking' in the early 2000s?
- A. Genetic engineering
- B. DIY biology ✓
- C. Synthetic medicine
- D. Cyborg ethics
Why: DIY biology, a grassroots movement encouraging hobbyists and citizen scientists to do biological experiments outside traditional labs, is closely associated with the early roots of the biohacking movement. Its growth in the 2000s helped shape the broader culture.
Q2. Which community is widely recognized as an early influence on the DIY biology and biohacking movement?
- A. Hacker and maker communities ✓
- B. Medieval alchemy guilds
- C. Professional pharmaceutical boards
- D. Military research agencies
Why: Hacker and maker communities, which valued open access, tinkering, and sharing knowledge, provided the cultural model and many participants for DIY biology. Their ethos of repurposing tools and openly sharing information carried over into biohacking.
Q3. What is the 'Open Source Biology' or open-science ethos mainly about?
- A. Keeping all research results secret for commercial gain
- B. Sharing methods, designs, and data freely so others can build on them ✓
- C. Restricting lab access to licensed professionals only
- D. Patenting every biological discovery immediately
Why: Open-source approaches emphasize transparency and free sharing of protocols, designs, and data. This principle drove many early biohacking projects and community labs.
Q4. Which early milestone helped make synthetic biology tools accessible to students and hobbyists?
- A. The creation of the BioBrick standard parts registry ✓
- B. The first commercial cloning of a mammal
- C. The publication of the first human genome in 1900
- D. The invention of the microscope in the 1950s
Why: The BioBrick standard, developed in the early 2000s at MIT and used in the International Genetically Engineered Machine (iGEM) competition, created standardized, interchangeable DNA parts. This lowered barriers for students and amateurs to design biological systems.
Q5. What broader concern is often raised about the growth of biohacking culture?
- A. That it makes lab equipment too expensive
- B. That it may outpace regulation and safety oversight ✓
- C. That it has eliminated the need for scientific peer review
- D. That it only involves computer programming
Why: Because biohacking often happens outside institutional settings, critics worry that safety practices, biosecurity, and ethical oversight may lag behind the pace of experimentation. This tension remains central to debates about the movement.

Q1. What does the term 'DIY biology' generally refer to?
- A. Large pharmaceutical companies developing drugs in-house
- B. Hobbyists and citizen scientists conducting biological experiments outside traditional academic or corporate institutions ✓
- C. Government agencies regulating genetic research
- D. Hospitals training doctors in laboratory procedures
Why: DIY biology refers to non-professional or independent practitioners who pursue biological experimentation, often in community labs or home settings, outside formal institutional frameworks.
Q2. Which type of space is most commonly associated with DIY biology communities?
- A. Community or hackerspace-style laboratories ✓
- B. Hospital surgical suites
- C. Federal research facilities
- D. Commercial pharmacies
Why: Many DIY biology groups operate out of community labs, makerspaces, or hackerspaces, which provide shared equipment and collaborative environments for members.
Q3. What is one widely cited goal of many DIY biology groups?
- A. Replacing all university research programs
- B. Making biological science more accessible and open to the public ✓
- C. Eliminating the need for laboratory safety rules
- D. Selling patented drugs at lower prices
Why: A common motivation is democratizing access to science education and tools, letting people learn and participate in biology regardless of formal credentials.
Q4. Why do responsible DIY biology communities typically emphasize safety and ethics guidelines?
- A. Because they are legally required to avoid all experiments
- B. Because working with biological materials can carry risks to people, the environment, and public health, so norms and oversight are important ✓
- C. Because safety rules only apply to professional scientists
- D. Because ethics review is unnecessary for non-professional work
Why: Biological work can pose real hazards, so community norms around containment, biosafety, and ethical conduct are central to maintaining trust and preventing harm.
Q5. Which of the following is a common activity in DIY biology communities?
- A. Hosting workshops and classes on basic lab techniques ✓
- B. Performing unsupervised clinical trials on humans
- C. Manufacturing and distributing prescription medications
- D. Conducting classified military research
Why: Workshops, community classes, and shared learning sessions are typical, helping members build skills in areas like microscopy, microbiology basics, and lab practice safely.
Module 3
Module 3: Nootropics and Cognitive Enhancement
Nootropics and Cognitive Enhancement
Knowledge check
Q1. What does the term 'nootropic' generally refer to?
- A. A prescription drug used exclusively to treat depression
- B. A substance claimed to improve cognitive functions such as memory, focus, or executive function ✓
- C. A type of physical exercise that boosts muscle growth
- D. A genetic therapy that alters brain structure permanently
Why: The term nootropic, coined in 1972 by Corneliu Giurgea, describes substances marketed as enhancing cognitive performance such as memory, attention, learning, or executive function. The category is broad and includes everything from prescription medications to supplements and foods.
Q2. Which of the following is a commonly cited nootropic supplement that is a source of L-theanine and caffeine in many people's routines?
- A. Creatine monohydrate
- B. Green tea extract ✓
- C. Vitamin K2
- D. Melatonin
Why: Green tea contains both caffeine and L-theanine, an amino acid that is often associated with calm alertness. Many biohackers use green tea extract or the combination of caffeine and L-theanine to support focus without jitteriness. Creatine is more associated with physical performance, while melatonin is mainly used for sleep.
Q3. Why is the evidence for many popular nootropics considered limited in biohacking communities?
- A. Most nootropics have been tested in large, long-term randomized controlled trials with consistent results
- B. Many studies are small, short-term, or conducted on animals, and results often do not replicate well in humans ✓
- C. Nootropics are banned from scientific study by regulatory agencies
- D. Cognitive effects can only be measured by brain scans, which are unavailable
Why: A large share of nootropic research involves small sample sizes, short durations, animal models, or industry-funded studies. Results in humans are frequently modest or inconsistent, which is why skepticism and careful evaluation of evidence are important in this field.
Q4. Which nootropic compound is most closely associated with the neurotransmitter acetylcholine pathway?
- A. Alpha-GPC (choline source) ✓
- B. Ibuprofen
- C. Omega-6 fatty acids
- D. Vitamin D3
Why: Alpha-GPC is a choline compound that supplies choline for the synthesis of acetylcholine, a neurotransmitter important for learning and memory. This is why it is popular among people seeking cognitive support, though human evidence for healthy adults remains mixed.
Q5. What is a key safety principle biohackers are often advised to follow when experimenting with nootropics?
- A. Stack as many compounds as possible at once to speed up results
- B. Introduce one change at a time, track effects, and consult a healthcare provider, especially with medications or health conditions ✓
- C. Use only unregulated products from online forums because they are more potent
- D. Avoid all supplements and rely solely on intuition
Why: Changing one variable at a time makes it possible to identify what helps or causes side effects. Consulting a healthcare provider is important because supplements can interact with medications or affect people with certain conditions. Stacking many unknown compounds and using unregulated products increases risk.

Module 4: Wearable Tech and Self-Quantification
Wearable Tech and Self-Quantification
Knowledge check
Q1. What does the term 'self-quantification' refer to in the context of biohacking culture?
- A. Measuring the body's data through tools to track health, performance, and habits
- B. Using mathematical formulas to predict lifespan based on genetics
- C. Designing custom computer chips to be implanted under the skin
- D. Competing in online fitness leaderboards without tracking personal data
Q2. Which of the following is a common metric measured by wearable fitness trackers?
- A. Blood glucose levels measured continuously through a needle sensor
- B. Heart rate, step count, and sleep duration
- C. Exact levels of circulating hormones such as cortisol
- D. Brain wave patterns read at the level of individual neurons
Q3. What is heart rate variability (HRV), a metric often tracked by wearables?
- A. The average number of beats per minute during exercise only
- B. The variation in time between consecutive heartbeats, often used as an indicator of recovery and stress
- C. The difference between resting heart rate and maximum heart rate
- D. The speed at which blood pumps through the arteries
Q4. Why is it important to consider accuracy limitations when using consumer wearable devices?
- A. Consumer devices are only accurate when worn on the dominant wrist
- B. Consumer devices often estimate metrics using algorithms and sensors that can vary in precision, so trends are often more reliable than single readings
- C. Consumer devices are legally required to display only approximate values
- D. Consumer devices cannot measure any biological data at all
Q5. What is a key principle of effective self-quantification practice?
- A. Collecting as much data as possible without ever reviewing it
- B. Setting a clear goal, tracking consistently, and reviewing trends to inform changes
- C. Changing every habit daily based on the latest single measurement
- D. Sharing all personal data publicly to ensure accountability
Module 5
Module 5: Gene Editing Tools and Ethics
Gene Editing Tools and Ethics
Knowledge check
Q1. Which gene editing tool is most widely known for using a guide RNA to direct a Cas nuclease to a specific DNA sequence?
- A. Zinc finger nucleases
- B. CRISPR-Cas9 ✓
- C. TALENs
- D. Restriction enzymes
Why: CRISPR-Cas9 uses a guide RNA to match a target DNA sequence, and the Cas9 nuclease then cuts both strands at that site. Zinc finger nucleases and TALENs rely on engineered protein domains for DNA recognition instead, and restriction enzymes cut DNA without guide-based targeting.
Q2. What does the 'germline' refer to in the context of gene editing ethics?
- A. Cells that only affect a single tissue type in the body
- B. Reproductive cells and embryos whose edits can be passed to future generations ✓
- C. Bacterial strains used as laboratory vectors
- D. Cells grown in culture outside the body
Why: Germline editing changes sperm, eggs, or early embryos, so the changes are heritable by descendants. This is why it raises far more ethical debate than somatic editing, which affects only the treated individual.
Q3. What is a major difference between somatic and germline gene editing?
- A. Somatic editing is always more effective than germline editing
- B. Germline edits are inherited by offspring, while somatic edits are not ✓
- C. Somatic editing requires no regulatory oversight
- D. Germline editing can only be done in plants
Why: Somatic edits affect non-reproductive cells and end with the treated person, while germline edits become part of the heritable genome. This inheritability is the central reason germline editing is more tightly regulated.
Q4. What is an 'off-target effect' in gene editing?
- A. A tool that fails to enter the cell at all
- B. Unintended edits at DNA sites that resemble but differ from the intended target ✓
- C. The deliberate removal of a gene from a genome
- D. A delay between editing and observable trait change
Why: Off-target effects happen when a guide RNA or nuclease acts on similar-looking sequences elsewhere in the genome. Minimizing these risks is an active area of tool design and a key safety consideration for any clinical use.
Q5. Why is informed consent particularly complex in self-experimentation with gene editing outside formal research settings?
- A. Because self-experimenters cannot read scientific literature
- B. Because risks may be poorly understood, outcomes unpredictable, and there is no independent oversight or ethics review ✓
- C. Because consent is only required for animal studies
- D. Because gene editing only works in people who have given consent
Why: Without an institutional review board, safety monitoring, or standardized protocols, individuals may underestimate harms such as off-target edits or immune reactions. Ethical frameworks emphasize that informed consent depends on adequate information and independent safeguards, which are often absent in do-it-yourself settings.
Module 6
Module 6: Fasting, Diet, and Longevity Practices
Fasting, Diet, and Longevity Practices
Knowledge check
Q1. Which of the following best describes intermittent fasting?
- A. Eating only processed foods for a set number of days each month
- B. Restricting eating to a defined window of hours within each day or fasting for specific days each week ✓
- C. Consuming only liquids such as juice and broth for an entire week
- D. Eating the same meal repeatedly to reduce decision fatigue
Why: Intermittent fasting refers to cycling between periods of eating and fasting, such as time-restricted eating (e.g., a 16:8 schedule) or alternate-day fasting. It is a pattern of timing rather than a specific food list or liquid-only diet.
Q2. What is the main physiological shift that researchers associate with extended fasting?
- A. A permanent increase in muscle mass without exercise
- B. A switch from relying mainly on glucose to using stored fat and producing ketones ✓
- C. Complete suppression of insulin for the entire day
- D. Rapid growth of new fat cells
Why: After glycogen stores are depleted, the body increasingly burns fatty acids and the liver produces ketone bodies. This metabolic shift is the basis for many fasting protocols, though its long-term benefits are still being studied.
Q3. Which statement about calorie restriction and longevity research is most accurate?
- A. Human trials have definitively proven that calorie restriction doubles human lifespan
- B. Calorie restriction extended lifespan in many animal studies, but human evidence is limited and mostly based on biomarkers ✓
- C. Calorie restriction has been shown to shorten lifespan in all species studied
- D. Longevity benefits only occur when calories are restricted by more than 75 percent
Why: Calorie restriction has extended lifespan in yeast, worms, flies, rodents, and other animals. In humans, studies such as CALERIE show improvements in markers like blood pressure and insulin sensitivity, but lifespan effects have not been demonstrated.
Q4. What is a common caution biohackers should consider before starting a prolonged fasting regimen?
- A. Fasting is harmless for everyone and never requires medical input
- B. People with diabetes, eating disorders, pregnancy, or certain medications may face serious risks and should consult a clinician ✓
- C. Fasting should always be combined with daily high-intensity exercise on an empty stomach
- D. Water should be avoided entirely during any fasting period
Why: Fasting can cause dangerous interactions, especially with insulin or blood pressure medications, and may be harmful for those with eating disorders or who are pregnant. Medical guidance is recommended for higher-risk individuals.
Q5. Which term describes a self-experimentation approach where individuals track personal data such as sleep, glucose, or fasting responses to optimize their habits?
- A. Passive dieting
- B. Quantified self tracking ✓
- C. Clinical placebo testing
- D. Metabolic averaging
Why: Quantified self refers to collecting personal data through wearables, blood tests, or logs to understand one's own body. It is a core practice in biohacking culture, though individual results vary and should be interpreted cautiously.
Module 7
Module 7: Regulation, Safety, and Responsible Practice
Regulation, Safety, and Responsible Practice
Knowledge check
Q1. Which of the following is the most important first step before attempting any self-experiment in biohacking?
- A. Ordering the substance online and starting immediately to gather data
- B. Consulting a qualified healthcare professional and reviewing the available evidence and risks ✓
- C. Asking members of an online forum to vouch for the product
- D. Doubling the recommended dose to speed up results
Why: Responsible practice begins with informed decision-making. Consulting a qualified clinician and reviewing the scientific evidence and potential risks helps identify contraindications, interactions, and safer alternatives before any intervention.
Q2. What does 'informed consent' mean in the context of a self-experiment?
- A. Agreeing to terms of service on a supplement website
- B. Understanding the known risks, potential benefits, and uncertainties of an intervention before choosing to undertake it ✓
- C. Having a friend sign off on your experiment plan
- D. Publishing your plan publicly so others can object
Why: Informed consent requires genuine comprehension of what is known and unknown about an intervention, including its risks, so that the decision to proceed is voluntary and well founded.
Q3. Why is the regulatory status of a product sold for biohacking purposes often important to check?
- A. Regulated products are always more effective
- B. Unregulated products may have inaccurate labeling, contamination, or unverified dosing ✓
- C. Regulation only affects shipping costs
- D. Unregulated products are always illegal to possess
Why: Products outside formal regulatory oversight may lack quality control, so the actual contents, purity, and dose can differ from what is labeled, creating safety risks.
Q4. Which practice best supports safe self-experimentation?
- A. Changing several variables at once to save time
- B. Keeping a detailed log of doses, timing, and observed effects, and changing one variable at a time ✓
- C. Relying on memory to recall how you felt weeks earlier
- D. Stopping all monitoring once you feel good
Why: Logging and isolating variables makes it possible to attribute effects accurately and to detect adverse reactions early, reducing both risk and misleading conclusions.
Q5. What is a reasonable response if you experience a serious adverse symptom during a self-experiment?
- A. Wait a few more days to see whether it passes on its own
- B. Increase the dose to counteract the symptom
- C. Stop the intervention and seek medical care promptly ✓
- D. Share the symptom on social media to crowdsource a fix
Why: Serious adverse symptoms warrant stopping the intervention and getting professional medical evaluation. Escalating the dose or delaying care can worsen harm.
