Microbiome Research

Human microbiome research, the study of the microbial communities (including fungi, bacteria and viruses) that inhabit the human body, is a rapidly growing field of research that has led to a greater understanding of the complex interactions between the human body and the microorganisms that inhabit it. 

Microbiome research has increased dramatically in recent years, driven by advances in technology and significant reductions in the cost of analysis. Research has unlocked a wealth of data, leading to the discovery of previously unknown interactions and effects, with the potential to lead to new diagnostic techniques and interventional strategies. Limitations remain including the high levels of noise in the samples, lack of unique connections between biological interpretations and experimental observations and unreliable comparisons across samples. But the potential for microbiome-based therapies, diagnostics and dietary modifications is increasingly gaining attention.

"Високосный год "Урожай" соберет" (leap year will gather the "Harvest") warns a Russian saying implying that there will be plenty of disasters - calamities, catastrophes and cataclysms. But usually there are not...

November 21, 2015: Where Are All the Wearables We Want to Wear?  Millions of years ago our ancestors straightened up and started carrying tools around, instead of dropping them after use. And so technology became a part of daily routine. Wearables promised to add more convenience than carryables and, ever since humans started to wear clothes some 170,000 years ago, there was no lack of attempts to turn useful products into wearables. But this was not easy...

November 12, 2015: All You Need to Know About Wearables  While cute and increasingly ubiquitous -- on the wrists, necks, or clipped to the body of all your friends -- many wearables are still single-purpose, redundant, or just plain useless, raising concerns about privacy and even etiquette. No wonder, there is a high return and product abandonment rate. Yet, the wearable future is coming faster than most futurologists thought ...

The Last Day of Summer  Is that it? Summer is finally over. And so is the sweet melancholy of August. Tomorrow is September, the second most stressful month of the year. known for stock market volatility, storms and tornadoes, the season of "back to school" and the time for a change ...

June 30, 2015: 
Technologies and Generations  Children no longer obey their parents and the end of the world is evidently approaching. So said a clay tablet inscribed almost 5 thousand years ago. But the world still stands, although we do go through golden and dark ages and societies rise and fall. Technology's golden age is now, or so we hope. How are current generations influenced by it and how will they shape the future world? ...

Making Digestion Health Easier to Digest  From balloons inserted into stomach or colon to the dreaded colonoscopy, digestive diagnostic procedures are not fun. Tracking diet and symptoms, too, is tedious and frustrating - unless, like a mouse, you can be isolated in a chamber linked to analyzers that automatically measure everything for you ...

March 25, 2015: 
The Smell of Stress and Fear  Can we recognize if people around us are stressed, anxious or fearful without observing their facial expressions, body language and actions or hearing their voice and messages? Can we understand if we are stressed ourselves without assessing our heart rate, blood pressure, noticing dry throat, sweating, drops or surges in energy? Yes, we can - by using our nose - as humans, too, recognize and transmit their emotions through chemical senses ...

On Luck, Skill and Hard Work - in Soccer and Life  Big data doesn't always get us closer to truth. Especially if there a fair bit of luck involved. And many think this applies to football/soccer games (Sally and Anderson, for example, say that soccer results are 50% luck). Yet data analysis provides valuable, sometimes counter-intuitive insights into this beautiful sport and the science of winning and losing in general ...

December 15, 2013: From Cyber Zombiness to Ambient Awareness  Dr. Phlox, the Enterprise surgeon, responded to the comment about movies (aka stories unfold on the screen) by answering: "Well, we had something similar a few hundred years ago, but they lost their appeal when people discovered their real lives were more interesting." At this stage of our evolution, virtual characters and screens are taking over our lives. ...

November 4, 2013: Keeping Pollutants Out with Exercise Food, drugs, air and everyday products like soap, cloth and grocery receipts are polluting our bodies with hundreds of toxic chemicals. New chemicals are constantly being introduced into our environment and the effects of most of them on human health are not known. About 30% of human diseases are due to environmental exposures as genetics is not the whole story  ...

October 29, 2013: IBS: pity, compassion and discrimination The effects of IBS on quality of life may be more substantial than those of many other chronic diseases. It affects school, work and life, putting the sufferers at risk for social isolation. ...

October 20, 2013: Are You What You Read or Do You Read What You Are? The environment plays a significant role in our health. We are exposed to multiple physical, chemical and biological challenges, including information - like news and gossip stories related to health and wellness. How exactly is it affecting us?...

September 11, 2013: Asthma in September Asthma sufferers know that when it rains it spores - as fungi and mold get moving through the air. But many don't realize that the most dangerous month for children's asthma symptoms is dry September. A study of hospital data found the spike in admissions in two to three weeks after the return to school. It happens in the United States, the United Kingdom, Mexico, Israel, Finland, Trinidad, and Canada...

September 7, 2013: Body odor and skin bacteria Our bodies are rainforests of microbes feeding off the leftovers from our meals and contributing to a variety of body odors. Human skin is inhabited and re-populated depending on health conditions, age, genetics, diet, the weather and climate zones, occupations, cosmetics, soaps, hygienic products and moisturizers. All these factors contribute to the variation in the types of microbes... 

August 18, 2013: Building 23rd century tricorder in the 21st The $10 million Qualcomm Tricorder X Prize and $2.25 million Nokia Sensing Challenges are trying to identify the best portable technologies for diagnosing disease - as easily as Dr. McCoy's tricorder of the 23rd Century could. What scientific knowledge could help us to develop it in this age? Detecting metabolites, sensing DNA, imaging the nanoworld of the human body or interaction between matter and energy?,,,

June 28, 2013: I Know What You Ate This Summer Despite active foodstagramming and foodteresting, and eagerness to show pictures of meals and diet reports to friends on social media, we don't really want others to know everything we eat. But they might know anyway...

June 6, 2013: When it Smells Like Team Spirit Why do we connect and collaborate, deciding to "walk in the light of creative altruism" instead of the "darkness of destructive selfishness"? Is it because of subtle behavioral clues that make us "click" and consider the other person a part of the group? Or is it because it smells like team spirit? It very well might be. We (literally) smell love, victory, fear, along with chemicals that motivate us to cooperate. As was recently shown in double-blind placebo-controlled studies that quantitatively measured generosity and cooperation...

May 14, 2013: Coffee: Bugs and Debugging Coffee can bug or de-bug you - in many different ways. It can actually energize your gut bugs. Nestle researchers showed that for sixteen healthy adult volunteers consuming a daily dose of 3 cups of coffee during 3 weeks. This led to an increase of the metabolic activity and/or numbers of Bifidobacterium species, important probiotics in the food industry...

May 1, 2013: Inhale and feel it with your heart All you need is love. Or failing that chocolate. And not only because dark chocolate could lower the risk of heart disease, blood pressure and sugar levels. As Dr. Schieberle's team recently discovered that heart could sense and enjoy the sweet smell of chocolate too. When they put small odor-emitting molecules from chocolate on one side of a dish, cells actually moved towards the aroma...

As a matter of fact, it highly correlates with tax fever - as found by Google Correlate algorithm comparing millions of web queries...

February 9, 2013: Will you get the flu this season? Worst of flu season may be over. But you can still catch a chill. If you shake hands with lots of sick people, for example. Or don't keep sufficiently warm. Yes, your mother has told you, and you thought it was just an old wives' tale, but it wasn't.

February 7, 2013: Big Data of Sounds Hearing begins with the ears, but it's more than the sum of sounds. We are able to recognize piano notes and experience music, understand speech in noisy surroundings and localize voice in 3D.

​January 31, 2013: Odors and Infections Many illnesses are associated with distinct odors. Especially those caused by infectious or opportunistic microbes inside the body or on its surfaces. Body odor of someone infected with C. difficile, for example, can appear "swampy", Rotavirus gives sharply sweet putrid smell that some people associate with wet dogs, H. pylori can create a range of foul odors, and pseudomonas infections can smell like grapes and bitter almonds.

December 24, 2012: Molehills and Mountains If you suffer from IBS, chances are you're very considerate of others and even possibly an anxious "catastrophizer." It was repeatedly concluded based on magnetic resonance imaging of the brain and psychological questionnaires - for students and non-students, Easterners and Westerners, right-handed and left-handed individuals.

November 29, 2012: Come out smelling like a rose You are what you eat. And you smell like your food. Well, it's actually a bit more complicated - as we emit complex combinations of volatile chemicals produced from food by our own metabolic system as well as microbes that call us home. Same foods can be translated into a wide range of odors, depending on the individual.

November 26, 2012: Close your eyes and tap your heels GPS shoes can point to where you're going, but how will they know where to go? By consulting the map uploaded via USB and its own GPS receivers, wirelessly communicating with each other. For future models, you could probably set up WiFi to let your shoes download more information, talk with other people's shoes and modify your route on the go. So your footware might need its own network access, like agent Maxwell Smart's left shoe with a mobile subscription plan.

September 25, 2012: Mirror, Mirror on the wall, Am I healthy after all? Health management applications will not be limited to smartphones or smart homes. All objects in our lives will gradually become "smarter." Mobile phones can already manage vacuum cleaners and thermostats. Refrigerators can tweet, check Google calendars, download recipes, play tunes and alert us about food spoilage. Mirrors can monitor our weight and exercise. There is still more emphasis these days on technological wizardry than on actual benefits, but systems like Aurametrix are bringing it all together and generating valuable insights.

August 5, 2012: Carbohydrates for your bacteria Our bacteria are picky eaters. Some of them - like Prevotelia - prefer a high carbohydrate diet, while others - like Bacteroides - stick to unhealthy western lifestyle with lots of meat and fat. The most prevalent bacteria in the gut of horses, cows and goats prefer people consuming alcohol and polyunsaturated fats. Methanobrevibacter is most abundant in anorexic nervosa patients. Gram negative bacillus Bilophila wadsworthia loves people with gangrenous appendicitis or those whose diets are high in milk fat. The most widely promoted prebiotics inulin and fructooligosaccharides seem to attract Bifidobacteria. What about diets low in poorly absorbed fermentable carbohydrates aka FODMAPs that seem to aggravate irritable bowel syndrome (IBS) ? Which bacteria is responsible?

June 23, 2012: Cars That Care Health technology of the future promises an easy life with no interruption in your daily activities. For example, information about your health could be collected while you're driving. A car is already viewed as a health platform and wellness coach by leading manufacturers. How would this work?

May 26, 2012: More apps, less flu? Fewer people caught the flu this season compared with past years. And many more apps tracking the flu have been developed. Any relationship between these two trends?

May 7, 2012: Finding the Goldilocks Solution A top story in today's news is related to a recent scientific paper published in Current Biology concerning the dinosaurs. British scientists wanted to know, "Could methane produced by sauropod dinosaurs have helped drive Mesozoic climate warmth?" By their estimates, some 520 million tons of methane (a "greenhouse gas" emission) were produced by the flatulent beasts every year. This begs the question, do flatulent humans today also contribute to global warming?

April 30, 2012 Why Red Beans And Rice Are Good What if an invisible digital nurse could take detailed notes about your physiology, psychology, symptoms and activities, and record the precise ingredients in your foods? And what if this digital nurse also could simultaneously collect information about your environment, including the weather, air quality, allergens and even disease outbreaks near your location? (Mendeley

March 11, 2012: Hello Summertime!.. Owls Beware Environment can significantly affect human health. And the risks are not limited to air pollution, seasonal allergies, tainted water or chemicals in food. Our life dramas are set against the backdrop of world events that contribute to environmental health too, to a lesser or greater extent. How does springing clocks forward affect our lives?

January 10, 2012: Studying body odor: one step at a time Unpleasant body odors could be a sign of a disease. But even when the cause of the disease is known - an example is trimethylaminuria or TMAU - there are no one-size-fits-all solutions. Elimination of choline and other essential nutrients from diet can be harmful and unhelpful. Everyone has their own unique needs, with individual combinations of foods, activities and optimal environmental conditions.

December 24, 2011: How does Christmas smell like? Like cinnamon! So say studies by European scientists. And even though the smell of cinnamon is described as "pungent" (besides "warm", 'sweet", and "spicy"), it fires up our brains, evoking a joyful Christmas mood and making us more generous. Cinnamon is classified as a stimulant. Smelling and tasting cinnamon could enhance attention and virtual recognition memory, at least in comparison to smells of peppermint, jasmine or cherries.

December 9, 2011: Can Software help Health care? Apps, apps and more apps. Software is everything and everything runs on software. Almost every industry in the U.S. has been disrupted by software. The health care field is not one of them. Easily accessible consumer information makes everyone a little bit doctor. Emerging portable diagnostic devices will strengthen the transition. Are we up to it?

December 6, 2011: The Road to Ammonia Why do I smell like Ammonia? This question, in thousands of variations, has been asked over and over again at every major question/answer site, especially teen, bodybuilding and athletic forums. The Internet provides plenty of opinions. Medical sites talk about diseases like chronic kidney failure, hepatic cirrhosis or H. pylori infection. Fitness sites recommend drinking more water, reevaluating protein sources and eating more carbohydrates. What are these diet-odor links?

November 12, 2011: Adding red to your diet A number of studies have suggested that a higher intake of lycopene-containing foods decreases the risk of heart disease, prostate cancer, other cancers and infections, even cataracts and asthma. What are the potential side effects?

August 14, 2011: Hold the Starch? Starch is that stuff that stiffens your shirts. It's also what most people eat for fuel. Wheat, rice, corn, oats, potatoes are all very starchy foods. Many popular diet plans call starch a second-rate food that should be avoided at all costs. No-starch and low starch diets are favored by irritable bowel communities, while former Weight Watchers, Jenny Craig and Atkins enthusiasts love the new Carb Lovers Diet praising starch. Yet, there may be something good about starch even for those with sensitive stomachs.

May 30, 2011: Tryptophan in food: Will it make you happy, sleepy or smelly? And the answer is ... either or all of the above. And this is not a complete list of all that can happen. In some rare conditions, for example, tryptophan could also make your pee purple.

April 4, 2011: Much Ado About Bowel Movement Want to manage your toilet metrics? There's an app for that. Actually, multiple apps - like this one recording precise GPS location of bowel events along with their shapes and odors or IBS symptom tracker and GI monitor, approved and designed by gastroenterologists. Yet, the lists of metrics provided by these applications are not complete.

April 1, 2011: The FODMAP diet "Functional gut" symptoms (bloating, wind, abdominal distention, discomfort, pain, altered bowel habits) can be controlled by diet, but most theories of how exactly food components are linked to symptoms are lacking consistency.

​February 2, 2011: Colonoscopy for everyone! ..or Gonna Buy Me A Dog New research from Japan brings good news: dogs can be almost as accurate as a colonoscopy exam.

December 17, 2010: Danger, Will Robinson!!! or injury prevention with sensors and algorithms Health is determined by many factors including Behavior (Physical Activity, Eating habits, Tobacco or substance abuse, responsible sexual choices), Mental Health, Injury and Violence, Environmental Quality, Preventative measures such as immunization, and Access to Health Care. Injuries are most likely to be perceived as "accidents" and "acts of fate", but they depend on the same determinants as other health factors: individual behavior, social and physical environment. The likelihood of injuries - unintentional ones and those caused by acts of violence - can be computed from physical location, gene-environment interactions, prior medical history, and physical traits.

October 12, 2010: You are the Chosen One, at least by your bacteria Host genomics is not the main decision-making factor for bacteria immigrating into human body, but it is an important factor. Two papers recently published in the Proceedings of the National Academy of Sciences help to understand why you are chosen and how the choosers make their decisions.

August 21, 2010: Of blood and breath: metabolite-based diagnosis of ovarian cancer Physicians always knew that breath contains clues to diseases. Chemicals in breath often correlate with chemicals in saliva and blood - be it alcohol, anaesthetics or other metabolites. Recent paper is claiming 99% to 100% accuracy of detecting ovarian cancer by metabolites in blood.

August 15, 2010: Predicting catastrophic health events "I've just picked up a fault in the AE35 unit. It's going to go 100% failure in 72 hours". These were famous words of the almighty computer HAL in "2001: A Space Odyssey". Few of us believe too much in software forecasts - be it weather, earthquakes or computer hard disk failures. Yet, we all know that sometimes it works. And such systems are very valuable, assuming they continuously improve.

August 11, 2010: On cancers and petroleum spills Researchers have known for years that microbiome-determined smell of cancer patients is chemically different from healthy individuals. One more study featured in British Journal of Cancer brings us a bit closer to an inexpensive, easy-to-use, portable device for home diagnostics.

December 21, 2009:  The Power Of Visualization  Networks and clustering methods help to uncover changes in complex large-scale systems, but more sophisticated approaches are needed to distinguish between real trends and noisy data, between meaningful structural changes and random fluctuations. This blog discusses ways to visualize data that can be applied to probiotic production (eg, scheduling information for batches with Gantt charts, alluvial diagrams for colonization dynamics and bubble graphs illustrating the operational taxonomic units)

August 28, 2009: Metabonomic Profiling as a Non-invasive Inexpensive Diagnostics Tool Metabolite profiling was shown to be a promising diagnostic technique for many diseases and conditions. 

Clinical Studies
  • NCT03582826  - Microbial Basis of Systemic Malodor and "People Allergic To Me" Conditions (PATM)
  • NCT04832932  - The safety profile and the magnitude and durability of immune responses to the COVID-19 vaccines as well as adverse reactions depend on health conditions, metabolism and microbiomes.
