New research will surprise those who think they have a high level of personal hygiene. A microbiological study of the sleeping areas of chimpanzees and human beds has found that, socially, the sleeping areas of chimps are cleaner.

The nature vs. nurture debate is one of the most hotly debated areas of science, in terms of predicting physiological outcomes. This issue has been reignited in terms of the human microbiome in a new study from Israel.

Research into to the human microbiome continues to produce new medical findings of interest. The latest news is a connection between an imbalance of microorganisms in the human gut and feelings of despair.

Moving from a field of academic research to commercialization, interest in the human microbiome has been accelerating over the past year with several big biotechnology companies involved. We take a look at the reasons why.

Budapest - A new study indicates that a naturally synthesized prebiotic can target and increase the growth of bacteria in the human gut which lead to a reduction in cholesterol levels. The research comes from the University of Reading in the U.K.

Understanding the types of microorganisms found in a typical hospital and whether they are pathogens is an important part of good governance. Such investigations need to go further and understand changes over time.

Scientists from Baylor College of Medicine have found that alterations to the circadian clock affect how the body responds to diet. In turn this influences microbes residing in the digestive tract.

Copenhagen - Antibiotics can adversely affect the health properties of whole grain. This appears particularly so for women. According to a new study, experimental findings show the importance of controlling the use of antibiotics.

Inflammation increases with age and this leads to ill-health problems. One of the triggers appears to be the balance of microorganisms in the gut. This is based on studies using mice and the findings may well apply to people.

Medical research suggests that a high concentration of indolepropionic acid in serum helps to protect a person against type 2 diabetes. Indolepropionic acid is produced by intestinal bacteria, and it is higher with a fiber-rich diet.

New York City - The oral microbiome (that bacteria found in the mouth) can, if imbalanced, enhance the risk of a person developing pancreatic cancer. The finding adds to growing reports about the association between human microbes and disease.

Toronto - Does keeping cats and dogs help to protect children from developing allergies and does it also help to reduce obesity levels? These are the indicators from a new U.S. survey on families that keep pets. The reason comes down to the human microbiome.

Milan - Can weight loss be achieved through the technique of magnetic brain stimulation? A recent study suggests this is possible and it works by altering the composition of the bacteria that reside in the human gut.

A new connection between the microbiome of the gut and human health and disease has been made. Here Parkinson's disease, along with the medications to treat Parkinson's, alter the composition of the trillions of bacteria that make up the gut microbiome.

Unhealthy gut microorganisms can trigger a rise in blood pressure and this can trigger the unhealthy effects of hypertension, according to new research. The research further reinforces the role the balance of human microorganisms play in disease.

Chicago - To better understand the infection risks to patients a plan has been drawn up to map the microbiome of hospitals. This is on the premise that each hospital carries its own, unique microbial signature.

The microbial content of dead bodies can be used to assess the time of death, based on new research. This requires analysis of the so-termed “necrobiome”, looking at the patterns of microbes on and within the deceased.

People who experience a 'nervous stomach' under periods of stress will understand the connection between the gut and a person’s mood. It seems that there is now scientific evidence to support this link.

Some people cope well with contact lenses, other suffer with itchy eyes or run into problems. The reason may be due to the microbial composition of the eye, according to a new study.

Austin - The composition of a person’s gut microbes appears to be a determining factor for immunotherapy, at least in relation to melanoma patients. This finding stems from a new study.
