For a first-year surgical resident, the appendix (specifically, it’s removal) represents a prized surgical operation. For trained surgeons, the appendectomy is usually an urgent affair that requires giving up sleep or angering patients who have their office care delayed. Understanding the “true” role of the appendix requires both the hygiene hypothesis and the microbiome.
A new video released by the magazine attempts to explain why there are more obese Americans today than 30-40 years ago. It claims that even if people eat healthy and exercise, it's easier to be obese today because of three factors -- but only one of those is likely to be correct.
A small study of the Thanksgiving cranberry raises the issue of when science in the public interest transitions from informing to advocacy and then to marketing.
We don't know if probiotics are a good idea during antibiotic therapy. So eat plenty of fiber -- such as fruits, vegetables, and whole grains -- instead.
The bacterial symbionts living in our gut, the microbiome, is subject to the evolutionary pressures our body – and by extension our diet, activity, and geography – create. Nature provides good examples of both change and resilience. Can we learn from those examples?
The authors had a clear strategy in mind: (1) Do a study on a common household object; (2) Produce boring data that doesn't surprise any microbiologist; (3) Write a provocative, fear-mongering headline; (4) Market it to a gullible, clickbait-hungry press, exhibiting no critical thinking; and (5) Watch the grant dollars roll in.
Colon cancer kills more than 50,000 Americans each year. One in 22 men and one in 24 women will be diagnosed with colon cancer in their lifetime. Currently, patients rely on colonoscopies to detect pre-cancerous growths called polyps. But doctors from John Hopkins University have discovered two digestive bacteria that form a film on the colon — months before the polyps appear.
A swallowable capsule may be useful in identifying transit time in the gut as well as the bacteria present. It is a new, simpler way to investigate our gut microbiome.
We cannot digest fiber, but some researchers believe fiber helps lower our blood pressure while maintaining cardiovascular health. It turns out that the fiber is being digested by the bacteria of our gut – and that process may play a role in controlling blood pressure.
Cirrhosis, the final stage of liver disease, is the 12th leading cause of death in the United States. Unhealthy bacteria in the mouth and gut appear to play a role.
We have been reading a bunch of nonsense about artificial sweeteners causing elevated blood glucose for years. A study out of Britain puts this to rest – and does so in no uncertain terms.
Most motorists, as they glide their cars carefully around the bloody remains, find highway carcasses repulsive. But a team of microbiologists and chemists from the University of Oklahoma hope that roadkill will prove to be a biomedical gold mine.
