It is always interesting to know more about your own history and ancestors. Learning about your past can be a fascinating and soul-stirring journey.
Your geographical origin pertaining to specific populations is referred to as ethnicity.
AncestryDNA offers an in-depth analysis of your DNA and helps you understand more about your family tree, and origins or find lost relatives.
So far, ancestry DNA has limited samples that have helped people determine where they belong.
In the latest update, AncestryDNA has announced its ethnicity update and added new regions in Asia, Africa, and Oceania.
Their vast collection of family trees also helps improve results with family histories spanning various regions worldwide.
This makes ancestry DNA’s ethnicity tests more precise.
This is for people who already have an AncestryDNA kit. This feature allows you to explore your family history using all the features that are included in the subscription.
After two weeks, you will be charged a monthly fee according to the plan you have chosen:
Asia

Did You Know? You can use your AncestryDNA test data to get up to 11 additional health and wellness reports from as low as $30. No new DNA test required. Reports within 24 hours.
According to the AncestryDNA website, "Storymaker Studio is a collection of tools to help you create, share, enhance, and preserve audio, images, and family stories." It includes the following tools:
Here’s what changed with AncestryDNA’s August 2022 update:
By adding more regions in Asia and Africa and splitting Oceania into Eastern Polynesia and New Zealand Maori, eight new areas were added, namely:
At AncestryDNA, their goal is to represent the world as fairly as possible.
Since people have always been and continue to move from one place to another, representing ethnic regions becomes crucial to determining where your ancestors lived and belonged.
AncestryDNA has divided the Oceana region into Eastern Polynesia and New Zealand Maori regions to make ethnicity results more accurate and precise.
These two regions were made to provide more precise results of both the Hawaiian and New Zealand Maori heritages.
However, it is essential to remember that since Eastern Polynesian indigenous populations (who descended from West Polynesia), people with Hawaiin and Maori heritage have some percentage of other East Polynesian regions in their results.
This update aims to increase precision and provide information about different ethnicities.
The update saw more addition of samples to the reference panel to expand the number and diversity of populations for comparing users’ DNA.
Further, AncestryDNA updated the DNA algorithm to provide more precise ethnicity estimate results.
This can result in new regions or changes in your percentages.
AncestryDNA’s latest update has added more unique profiles and different regions of the world to differentiate neighboring regions better and improve existing ones.
With the latest update, people with Indigenous roots in Cuba, Haiti, or the Dominican Republic will notice more improvements.
Similar improvements will also be seen in people from the following regions:

Existing customers who already have their AncestryDNA ethnicity profiles may see changes or updates in their ethnicity percentage with this new update.
This is because their recent update expands the number and diversity of populations they compare your DNA to during the test.
The last update was in September 2024. Typically the updates are done during fall. So the next ancestry DNA update will likely be in July, August, or September of 2025.
AncestryDNA typically updates their results once every year.
In our continuous pursuit of optimal health and well-being, biohacking emerges as a revolutionary approach that leverages our understanding of biology and genetics to tailor lifestyle and wellness practices. Biohacking isn't just about extreme dietary changes or sophisticated technology; it's about making small, informed tweaks to your daily habits to improve overall health. Here, we present seven easy-to-implement biohacks based on genetic insights and practical wisdom to help transform your health today.
Chronic gut issues such as abdominal cramps, nausea, bloating, and gas may indicate underlying food intolerances.
Rather than abruptly eliminating certain food groups, employing an elimination diet can help identify triggering agents.
By gradually reintroducing specific foods and monitoring their effects, individuals can pinpoint triggers and make informed dietary adjustments.
Pro tip: A nutrition genetic test can help identify your risk for food intolerances and allergies, thereby cutting back on trial and error. Such tests examine a certain group of genes that are associated with abnormal responses to certain foods and check if you carry any “risky gene changes.”
Did you know that coffee (black) is one of the beverages that have consistently, across many decades and populations, been scientifically proven to have health benefits?
So, you can consider switching from milk to black coffee. Start by adding less and less milk to your coffee to wean off slowly.
Notice how caffeine affects your body - caffeine jitters and sleeplessness - and moderate your caffeine intake accordingly to biohack your body into responding favorably to caffeine.
The reason why caffeine affects different people differently is that some of us harbor a change in the caffeine-processing gene, due to which we metabolize and eliminate caffeine slowly.
These “slow metabolizers” may be better off finishing their last cup of coffee before 2 PM.

The hardest thing about working out is being consistent.
A busy schedule, lack of motivation, pain and injury, not seeing desired results, and a lot of other things can prevent us from exercising regularly.
Setting SMART (specific, measurable, attainable, relevant, and time-bound) goals can help keep you focused and motivated.
Working out with a partner adds motivation and accountability, making exercises more enjoyable.
Equally important is allowing your body sufficient rest between workouts to prevent burnout and injury.
Did you know? Your muscle fibers “naturally” support certain types of activities - endurance or power-based. Further, there are also genetic factors at play here, which could influence your injury risk, ligament strength, motivation, recovery pace, etc. Having an understanding of your genetic profile can help you tailor your workouts to your body type and get optimal results.
Cold showers can boost circulation, reduce muscle soreness, and potentially increase your alertness and resilience to stress.
They have been shown to have positive effects on white fat, brown fat, and the body’s immune defenses.
In contrast to hot showers, cold showers have a short list of drawbacks, primarily related to discomfort and potential risks for individuals with certain health conditions.
It's recommended to gradually ease into cold showers, starting with shorter durations and increasing the time and frequency.
It's also essential to consult a healthcare professional before starting cold showers if you have certain medical conditions.
Deep breathing exercises, such as the 4-7-8 technique or box breathing, can have an immediate calming effect on the nervous system.
These practices can be done anywhere, anytime, and serve as powerful tools for managing stress, improving focus, and enhancing overall well-being.
It involves inhaling for 4 seconds, holding the breath for 7 seconds, and exhaling for 8 seconds.
This method, derived from an ancient yogic technique known as pranayama, aims to activate the parasympathetic nervous system and reduce anxiety.
Also referred to as square breathing, it is another deep breathing method used for stress and anxiety management.
It entails taking slow, deep breaths in a specific pattern to promote calmness and focus.
The technique involves inhaling for 4 seconds, holding the breath for 4 seconds, exhaling for 4 seconds, and then pausing for another 4 seconds before beginning the cycle again.
The critical role of sleep in maintaining health is widely recognized, with the ideal recommendation being around 8 hours per night.
However, challenges like difficulty falling or staying asleep, insufficient deep sleep, and sleep disorders such as snoring and insomnia can significantly impact sleep quality, leading to exhaustion.
While some sleep issues may necessitate medical intervention, many can be addressed with practical biohacks to enhance sleep quality.
It is a highly effective, research-backed technique for improving sleep without needing special equipment.
It involves tensing and then relaxing muscle groups sequentially, promoting physical relaxation conducive to better sleep.
Advancements in technology have also provided tools for sleep improvement, such as smartphone apps that use the device's accelerometer to monitor and analyze sleep patterns.
These apps offer an easy way to track and understand sleep behaviors, facilitating targeted adjustments to improve sleep quality.
Your diet plays a crucial role in sleep health, not just in terms of what you eat but also when you eat.
Including starchy vegetables in your evening meal and consuming magnesium-rich foods like leafy greens, nuts, seeds, and whole grains can enhance sleep.
Additionally, foods containing natural melatonin, such as cherries and walnuts, can support sleep quality.
Your DNA influences sleep, affecting susceptibility to disorders like sleep apnea, insomnia, and narcolepsy, as well as individual sleep needs and preferences (chronotype).
Understanding these genetic factors can offer insights into personalized strategies for improving sleep, potentially mitigating risks associated with sleep disorders.
The Top 3 Methods To Fall Asleep Faster
Biohacking offers a range of unique and research-backed methods to enhance mental well-being, going beyond common practices.
Certain supplements, such as ω–3 fatty acids and SAMe, have been found to be effective in the treatment of affective disorders and shown to improve symptoms of depression.
Additionally, prebiotics, probiotics, and postbiotics are used to positively influence the composition of the intestinal microbiota, with potential benefits for mental health.
Furthermore, leveraging heart rate variability (HRV) measurements and stress management techniques can provide valuable indicators of mental and psychological health, empowering individuals to optimize their overall well-being and performance.
The journey towards improved health and well-being is a multifaceted one, enriched by the insights offered through genetic understanding and the practical application of actionable biohacks.
The seven strategies discussed here underscore the remarkable potential of blending genetic knowledge with everyday lifestyle adjustments to create a truly personalized approach to health.
Whether it's through dietary modifications, optimizing sleep routines, or tailoring physical activity to align with our genetic predispositions, these biohacks empower us to take proactive steps in enhancing our quality of life.
They serve not only as a testament to the transformative power of biohacking but also as a guide for anyone seeking to navigate the complexities of health and wellness with informed, intentional actions.
This convergence of science and self-care opens new avenues for achieving and maintaining optimal health, illustrating that with the right knowledge and tools, we have the ability to significantly influence our health outcomes.
It is essential to consult healthcare professionals before making significant lifestyle changes, particularly for those with pre-existing health conditions or specific dietary restrictions. While biohacks can complement conventional approaches, they should not replace professional medical advice or treatment. Individual responses to biohacks may vary, and it is important to approach these strategies with mindfulness and awareness of personal limitations and sensitivities.
The term ‘saturated fat’ has been associated with dietary red flags for years. Several studies have shown that saturated fats can cause cholesterol buildup, arterial blockage, and poor overall health. However, new research says these may be due to even-chain saturated fats - molecules with an even number of carbon atoms. On the other hand, odd-chain saturated fats like C15 fatty acids could be the key to promoting several facets of overall health. Are they really as healthy as they seem?
C15:0, or pentadecanoic acid, is an odd-chain saturated fatty acid.
It has an odd number of carbon molecules (15 to be exact) in its rigid, chain-like structure.
C15:0 exists in trace levels as dairy fat in butter and other milk-based products.
There’s a taboo surrounding all saturated fats, so how come odd-chain saturated fats promote health?
The answer lies in their metabolism.
Even-chain saturated fatty acids break down to produce acetyl CoA. This molecule helps generate energy through the Krebs cycle and promotes fat storage.
Odd-chain saturated fats break down to produce propionyl CoA, a molecule whose primary function is to replenish energy through the Krebs cycle. It doesn’t promote fat synthesis and storage.
Thus, odd-chain saturated fats are healthier than even-chain saturated fatty acids.
In fact, pure C15:0 in the body performs several functions.
It can:
To produce a 15-carbon-long fatty acid, your body can either concatenate smaller fatty acids or break down larger ones. Here’s how these processes work:
Experts agree that the ideal concentration of C15 in the bloodstream is 10-30 micromoles (µM). Consuming 100 to 300mg of C15 daily can maintain healthy levels of this fatty acid.
Since research is ongoing, experts haven't finalized the exact limits and range yet.
A C15 deficiency could set in if you don’t consume at least 100mg of C15:0 daily.
The mitochondria regulate metabolism at a cellular level.
As you age, the processes in your mitochondria slow down, leading to a poorer metabolic rate and easier onset of more diseases.
C15 molecules can be elongated to C23:0 fatty acids, which can then be broken down into valuable compounds like propionyl coenzyme A (CoA).
Propionyl CoA helps replenish and prolong the Krebs cycle, an essential part of metabolism.
Thus, C15 can help restore metabolic function in aging people.
C15 can be converted to penta-decyl-carnitine (PDC).
PDC can cross the (very selective) blood-brain barrier and influence the chemical environment there.
PPARα is a receptor that controls inflammation and metabolism in several body parts.
Beyond the blood-brain barrier, it promotes better cognition, sleep, and overall mood.
Research has shown that C15:0 can activate the PPAR pathway to a moderate extent.
This finding was confirmed across different genes and receptors, proving that C15 can improve overall brain health.
Several studies have investigated the effect of odd-chain saturated fats (15:0 and 17:0) on plasma glucose levels.
They found an inverse relationship between these factors, meaning that higher levels of C15 were associated with lower fasting plasma glucose levels.
This relationship is clinically relevant across different liver fat levels, BMIs, ages, and sexes.
Whole milk contains several even-chain saturated fats, such as stearic and palmitic acid, which have been associated with several health complications in the long term.
Consequently, the consumption of whole-fat milk has decreased, but the prevalence of heart disease has persisted.
An 18-year-long study of over 25,000 people noted that children who regularly consumed whole-fat milk while growing up were less likely to be obese or have dangerous heart conditions.
This is likely due to the effect of the trace content of odd-chain saturated fatty acids (like C15) in whole milk.
The harmful effects of overconsuming saturated fats were established decades ago.
As health awareness grew, people avoided them, but the prevalence of life-threatening metabolic diseases didn’t waver.
With the recent light shed on the benefits of odd-chain saturated fats like C15, scientists have noted that its population-wide concentration is lower than it should be due to the taboo around all saturated fats.
Despite being an essential fatty acid, its endogenous production (within the body) is extremely slow.
Thus, some experts recommend consuming more C15 through diet or supplementation.
Dairy fats like butter are the best dietary sources of C15, with up to 880mg of C15 per 100g of butter.
However, they are also laden with unhealthy, even-chain saturated fats.
Cattle meats like beef have around 350mg C15 per 100g of butter.
Like omega-3 fatty acids, C15:0 is also naturally present in fatty fish, with 160mg of C15:0 per 100g.
The vitamins with the most significant impact on C15 levels are:
Seraphina Pharmaceuticals has obtained an exclusive license to produce and distribute C15 supplements.
Their fatty15 capsules contain 100mg of C15, and they recommend consuming one a day.
The recommended duration for C15:0 supplementation is 12 weeks.
This regimen has helped lower glucose, cholesterol, inflammation, and rate of weight gain in models of obesity, diabetes, and fatty liver disease.
Several studies have validated C15:0’s ability to activate beneficial receptor pathways across the body, enhancing overall health.
Stephanie Lappe, a registered dietitian, reviewed fatty15 and rated it 4.2 out of 5 stars.
“The unfolding research on C15:0’s benefits is fascinating. As a dietitian and health enthusiast, I’m eager to see if and how future research on Fatty15 and the role of C15:0 shapes dietary recommendations”, she said.
However, there haven’t been enough validated studies in human populations to confirm the positive effects of C:15 supplementation.
Seraphina Pharmaceuticals has an A+ rating on the Better Business Bureau and a perfect 100% on ScamAdvisor.
On Reddit, it has a positive word of mouth, with several customers praising its effect on overall health.
Since it’s relatively new, most consumers have an overall positive opinion of Fatty15’s supplements.
The FDA has certified Fatty15 as ‘generally recognized as safe (GRAS)’.
There are no warnings against taking the supplements while pregnant or breastfeeding. So far, no reported side effects or contraindications of C15 have been reported.
C15 supplements can significantly benefit people who generally avoid dairy.
This can include people on a strict vegan diet or those with lactose intolerance.
Since it can boost metabolism, it can also benefit people who are starting to see the downsides of aging.
People who regularly consume C15 through dairy fats like butter may not need C15 supplementation.
They can meet their C15 requirements quickly.
It’s always best to consult a registered dietitian, nutritionist, or physician before starting or stopping a supplement regimen,
The best natural source of C15 is unsalted butter, with around 880mg of C15 per 100g.
The best non-dairy source of C15 is cattle beef, with 350mg of C15 per 100g.
Since C15 plays a significant role in metabolism and energy production, people with C15 deficiency exhibit general symptoms like fatigue and poor sleep, but they are also at a higher risk of developing conditions like anemia, heart disease, and diabetes.
According to Fatty15, a company that sells C15:0 supplements, C15 is healthier than omega-3 fatty acids because it provides more health benefits, nourishes and supports more kinds of cells, and is non-toxic to virtually all cells.

AncestryDNA vs 23andMe: Which Is Better For Raw Data Analysis?
2024 Update: Free Tools For 23andMe, AncestryDNA, FTDNA Raw Data Analysis
How To Login To Your Ancestry DNA Account + Health Reports At 55% Off!
While most genetic ancestry testing companies reveal how much DNA you share with people in their database, not many tell where they potentially end up on your family tree. The 23andMe family tree feature, which can be found in the “Family & Friends menu” of your account, provides a visual representation of potential relationships you share with those who have taken a 23andMe test. In this article, we'll walk you through how to use the 23andMe Family Tree. We'll cover everything from creating your tree to editing and sharing it.
Did You Know? Your 23andMe DNA data includes 700,000 markers, which can be used to learn everything from disease risk and drug sensitivities to nutritional requirements and fitness parameters. Learn more.
A family tree is a visual representation or diagram that displays the familial relationships and connections between individuals across different generations within a family.
It is typically presented in a tree-like structure with branches and leaves, where each branch represents a family line or generation, and each leaf symbolizes an individual.
A family tree is like a map of your family's history. It can be used in several ways, such as:
The 23andMe family tree feature predicts your family tree based on shared DNA with people in 23andMe’s database.
It compares and calculates many different ways you could be related to each other.
This feature is only sometimes accurate since it uses predicted relationships instead of confirmed ones.
However, it can be a helpful starting point for building your family tree or connecting with genetic relatives.
The 23andMe Family Tree analyzes your DNA data, makes age-based predictions, and calculates potential genetic relationships.
Here's how it works:
Information about living family members is private and visible only to you, while your DNA relatives and connections can see details about deceased ancestors.

23andMe's Family Tree feature uses Bonsai software to analyze DNA and determine how people are related.
Bonsai uses a variety of factors to make its predictions, including the amount of DNA shared, the pattern of DNA segments, and the ages of the individuals involved.
In the past, Bonsai had difficulty accurately predicting the relationships between close family members, such as aunts, uncles, and half-siblings.
It was challenging to distinguish between these relatives as they share similar amounts of DNA.
To address this issue, 23andMe recently introduced a new technique that examines the DNA of full siblings.
Full siblings share about 25% of their DNA, and they have a unique pattern in their DNA that helps Bonsai tell if someone is their aunt or uncle.
This new technique has significantly improved the accuracy of Bonsai's predictions for close family relationships.
Overall, Bonsai is a powerful tool that can be used to determine how people are related accurately.
Here are the steps on how to edit your 23andMe family tree:
No, you cannot view other people's genetic trees on 23andMe.
23andMe allows you to find and connect with genetic relatives using the platform's DNA Relatives feature.
However, this interaction is based on genetic matches and shared DNA segments rather than viewing the detailed genetic trees of others.
You can participate in the DNA Relatives feature and choose the level of privacy you're comfortable with.
The amount of detail I got from all of the reports was incredible. I had done 23andme quite awhile ago, and it was great, but this was truly next level. I'm going through some health issues and trying to figure out what's wrong, and Xcode Life has given me new language to ask my care providers about. I HIGHLY recommend this to anyone in a similar situation or just someone wanting to know more about their genetics. The detail is absolutely incredible.
- Katherine Krieger
Currently, 23andMe does not provide an option to export or share your genetic tree with others directly.
It is designed to be private and is only visible to the person who created it.
This privacy measure is in place to safeguard the personal information of individuals and their families.
Shortly, 23andMe may permit users to export their genetic trees.
While waiting for this feature to become available, there can be some alternative methods you can use to share your genetic tree with others:
While this approach can be more time-consuming, it offers a dynamic and visual presentation of your family connections.
Consider privacy and consent when sharing your genetic tree, especially if it will be public or widely distributed.
23andMe's Family Tree estimates are considered very accurate. However, when additional markers are included in ancestry analysis, the estimates may change.
23andMe generates the family tree for you and displays your relatives who have opted-in to the DNA relatives feature.
Half-siblings can be found in the "DNA relatives" or "Your connections" sections in your 23andMe dashboard.
While full siblings are shaded in only purple or purple + pink, half-siblings are shades only in pink.
The 23andMe Family Tree is a valuable feature that allows you to visually represent your family history based on your shared DNA with other 23andMe users.
To use the 23andMe Family Tree, you first need to opt-in to DNA Relatives. This action enables 23andMe to compare your DNA with that of other users and generate a comprehensive list of potential relatives for you.
Once you've compiled this list of potential relatives, you can construct your family tree. This can be achieved by manually adding individuals to your tree or accepting the predictions that 23andMe offers based on your shared DNA data.
Moreover, you can edit your family tree whenever you desire. This includes adding or removing people, changing their relationships, and adding additional information about them.
While the 23andMe Family Tree is a powerful tool for exploring your family history, it may only sometimes be accurate.
23andMe's new technique that examines the DNA of full siblings has greatly improved prediction accuracy for close family relationships. This makes the 23andMe Family Tree an increasingly valuable resource for those who want to learn more about their genetic heritage.
Did you know the ancient Greeks considered having one eyebrow beautiful? Other cultures believe thicker eyebrows are attractive. Not everyone is born with the same eyebrows. Whether you pluck your eyebrows to make them thin or allow them to grow thicker, the thickness of your eyebrows lies in your genes. In this blog, we will learn more about why some people have thicker eyebrows and how genes influence them.
Having thick eyebrows has a lot to do with your genes, and that's why this trait often runs in families.
While no single region or ethnicity is responsible for the origin of thicker eyebrows, the trait has had an interesting journey through time.
Ancient Egyptians used black paint to thicken their eyebrows to match those of their god, Horus.
Post WWII, women began to grow their eyebrows out, a trend pioneered by the most prominent celebrities of the time, including Marilyn Monroe.
Today, thicker eyebrows are commonplace.
Thick eyebrows are more than just a good grooming routine.
While there is limited knowledge about why some people have thicker eyebrows, it is certainly genetic to an extent.
Thick eyebrows are a dominant trait compared to thin eyebrows.
If one of your parents has thicker eyebrows, you'll likely have them, too.
However, more research is required in this regard.
Eyebrow thickness is a dominant, non-X-linked trait.
You can inherit the trait from either parent if they carry it.
Current evidence suggests that several genes can influence eyebrow characteristics.
The exact mode of inheritance could differ for each gene.
Researchers have identified three previously unreported genes linked to eyebrow thickness in people of European descent– SOX11, MRPS22, and SLC39A12.
Similarly, two genes– SOX2 and FOXD1 have links to eyebrow thickness in non-Europeans.
Two other eyebrow-related genes, EDAR and FOXL2, usually express themselves in non-Europeans but do not affect Europeans.
Studies have shown that a specific region on the EDAR gene can help predict the thickness of eyebrows.
Mutations (abnormal changes) in this EDAR gene can also lead to dysfunction of other hair characteristics.
Thick eyebrows are also a common symptom of several genetic conditions.
A few of these conditions include:
If you think the appearance of your eyebrows has more to do with grooming, think again!
The way your eyebrows look has more to do with your genes.
Four genes have been identified that affect eyebrow hair texture, one gene that determines the shape, and five genes that influence eyebrow color.
While your genes determine the shape of your eyebrows, environmental factors can also influence how your eyebrows look.
For example, years of waxing and tweezing eyebrows can affect their shape.
Any damage or injuries to the skin near the eyebrows can also affect hair growth and shape.
A unibrow or synophrys is a normal variation of the human eyebrow.
In many ancient cultures, having a unibrow was considered an attractive feature in men and women.
Today, however, the Western civilization finds a unibrow unattractive.
Like other attributes of eyebrows, having a unibrow is also influenced by genes.
The inheritance of a unibrow is polygenic. This means several genes may influence the appearance of a unibrow.
A unibrow has also been associated with developmental defects or syndromes, such as:
Let's learn more about eyebrow thickness and genetics in these FAQs:
If you have thin or narrow eyebrows, there are many remedies that you can use to increase the thickness of your eyebrows:
Men usually have thicker eyebrows than women.
Therefore, thicker eyebrows have always been perceived as a masculine trait.
However, many women have thicker, bushy eyebrows.
Men tend to have thicker brow ridges than women.
This can be attributed to several factors:
