Gut Bacteria Divide People Into 3 Types, Scientists Report

Gut Bacteria Divide People Into 3 Types, Scientists Report
Correction Appended In the early 1900s, scientists discovered that each person belonged to one of four blood types. Now they have discovered a new way to classify humanity: by bacteria. Each human being is host to thousands of different species of microbes. Yet a group of scientists now report just three distinct ecosystems in the guts of people they have studied. Blood type, meet bug type. “It’s an important advance,” said Rob Knight, a biologist at the University of Colorado, who was not involved in the research. The researchers, led by Peer Bork of the European Molecular Biology Laboratory in Heidelberg, Germany, found no link between what they called enterotypes and the ethnic background of the European, American and Japanese subjects they studied. Nor could they find a connection to sex, weight, health or age. Photo The microbes alter the gut so that only certain species can follow them. Dr. “Some things are pretty obvious already,” Dr. Dr. In the recent work, Dr. Still, Dr. Dr.

The Root of Health - Dysbiosis Did you know... This polluted pond is overgrown with bacteria...similar to what happens when your gut is overgrown with the bad guys.There are more bacteria in the gastrointestinal tract than there are cells in the bodyThe bacteria in our gut weigh approximately 4 lbsThere are an estimated 400-1000 different species of bacteria in our GI systemJust like we belong to one of four blood types, recent research shows we can be classified into 3 bacterial ecosystems.Some liken gut flora to a "forgotten organ" due to the extensive role they play There are good guys and bad guys in the world of the gut. When we're first born, our bodies are quite pristine and the digestive tract is sterile. Immediately we are presented with breast milk and environmental factors, both of which begin colonizing our digestive tract with bacteria - most of them beneficial and harmless.

Scientists discover an on/off switch for aging cells (Medical Xpress)—Scientists at the Salk Institute have discovered an on-and-off "switch" in cells that may hold the key to healthy aging. This switch points to a way to encourage healthy cells to keep dividing and generating, for example, new lung or liver tissue, even in old age. In our bodies, newly divided cells constantly replenish lungs, skin, liver and other organs.

Robin Rinaldi Takes A Year Off From Marriage-Wild Oats Project Facebook Advertisement - Continue Reading Below We think it's fair to say that every married gal gets a little antsy on occasion and Robin Rinaldi, author The Wild Oats Project is no exception. On the Sheath: Lecture Three: Intestines, Mesentery and Digestion Intestines, Mesentery and Digestion 4th October 1947. We shall discuss this morning the two preparations which deal with dandelion and chamomile on the one hand, and the intestine and the mesentery on the other. In doing so, I am very much aware of our lack of knowledge and understanding of everything connected with the metabolism of the human being and the higher animals. The metabolic process, the process of digestion, is still, for the scientist as well as for us who try to follow up Spiritual Science, if we are honest with ourselves, hardly anything but a mystery and a riddle.

Aging of Brain and Muscles Reversed Through Protein Therapy As we age, our muscles and brain don’t retain their qualities that they did during youth. However, a recent study has shown that protein therapy can help restore muscles and brains to their former glory through therapy with the protein growth differentiation factor 11 (GDF 11). The study was led by Amy Wagers and Lee Rubin from Harvard’s Department of Stem Cell and Regenerative Biology (HSCRB) and Harvard Stem Cell Institute (HSCI) and the results were published in two papers that have both been published in Science. The mice used in this experiment have the muscle and brain function that is equivalent to a 70 year old human. Concentrations of GDF 11 are much higher in younger mice than older mice, so the researchers sought to increase levels in older mice. In one of the studies, an older mouse was surgically connected to a younger mouse, allowing them to share a blood supply.

Staring into someone’s eyes for 10 minutes induces an altered state of consciousness A psychologist in Italy has figured out how to induce a drug-free altered state of consciousness by asking 20 volunteers to sit and stare into each other’s eyes for 10 minutes straight. Not only did the deceptively simple task bring on strange ‘out of body’ experiences for the volunteers, it also caused them to see hallucinations of monsters, their relatives, and themselves in their partner’s face. The experiment, run by Giovanni Caputo from the University of Urbino, involved having 20 young adults (15 of which were women) pair off, sit in a dimly lit room 1 metre away from each other, and stare into their partner’s eyes for 10 minutes.

Research Review: Leptin, ghrelin, weight loss – it’s complicated It’s a grim statistic: Most people who go on a diet and lose weight end up regaining that weight within a year. Doesn’t sound too promising. Why does this happen? Well, there are many reasons. The big one is that people view a “diet” as a short-term solution and don’t really change their behaviours — which is why our Precision Nutrition Coaching program focuses on sustainable, permanent change. Why Occupy? This was my opening blog post from February 12, 2012. I thought it might be helpful to keep it as a permanent page. “I came because by being physically present at Occupy Wall Street, I could increase, however marginally, the likelihood that more people would look in my direction.” – Jason Fitzgerald

Humans differ in their personal microbial cloud Introduction Humans harbor diverse microbial assemblages in and on our bodies (HMP Consortium, 2012), and these distinctly human-associated bacteria can be readily detected inside of buildings on surfaces, in dust, and as bioaerosols (Hospodsky et al., 2012; Täubel et al., 2009; Fierer et al., 2010; Flores et al., 2011; Flores et al., 2013; Meadow et al., 2013; Kembel et al., 2012; Kembel et al., 2014). Human-associated bacteria disperse into and throughout the built environment by three primary mechanisms: (1) direct human contact with indoor surfaces; (2) bioaerosol particle emission from our breath, clothes, skin and hair; and (3) resuspension of indoor dust containing previously shed human skin cells, hair and other bacteria-laden particles.

Why great ideas come when you aren’t trying History is rich with 'eureka' moments: scientists from Archimedes to Isaac Newton and Albert Einstein are said to have had flashes of inspiration while thinking about other things. But the mechanisms behind this psychological phenomenon have remained unclear. A study now suggests that simply taking a break does not bring on inspiration — rather, creativity is fostered by tasks that allow the mind to wander. The discovery was made by a team led by Benjamin Baird and Jonathan Schooler, psychologists at the University of California, Santa Barbara. The researchers presented 145 undergraduate students with two 'unusual uses' tasks that gave them two minutes to list as many uses as possible for everyday objects such as toothpicks, clothes hangers and bricks.

Chronic fatigue syndrome Although there is agreement that CFS poses genuine threats to health, happiness and productivity, various physicians' groups, researchers and patient advocates promote differing nomenclatures, diagnostic criteria, etiologic hypotheses and treatments, resulting in controversy about many aspects of the disorder. The name "chronic fatigue syndrome" is controversial; many patients and advocacy groups, as well as some experts, believe the name trivializes the medical condition and they promote a name change.[15] Classification[edit] Notable definitions include:[7]

What's Your True Sexual Orientation? The Purple-Red Scale Is Here to Help You Find Out When reality TV dumpling Honey Boo Boo Child declared that "everybody's a little bit gay" three years ago, she was unknowingly taking a page out of sexologist Alfred Kinsey's book. His famous Kinsey scale, which identifies people's levels of same- or opposite-sex attraction with a number from zero to six (zero being exclusively straight, six being exclusively gay), has been a favorite cultural metric for measuring sexual orientation since it was created in 1948. But even though asking someone where they fall on the Kinsey scale is now a common dating website opener, the Kinsey scale is far from an all-inclusive system. As Southern California man Langdon Parks recently realized, the scale fails to address other aspects of human sexuality, such as whether or not we even care about getting laid in the first place.

Motivation Losing weight takes more than just a diet and exercise plan. Those who lose weight and keep it off know that it also takes motivation, realistic goals, and a network of support. Learn how to get what you need to make your weight loss goal a reality. Set Goals and Motivate Yourself Goal setting and motivational skills might seem like the last thing you need to think about when you go on a diet, but the truth is that they play a major role in your success. Pam Killeen - Nutritional Balancing What is Nutritional Balancing? Nutritional Balancing honors the fact that we are all individuals with our own unique metabolic blueprint. It involves a different paradigm than traditional medicine. Standard medical treatment is based on the naming of a disease or a condition whereby a remedy or treatment is then prescribed.
