Digestion is the mechanical and chemical breaking down of food into smaller components, to a form that can be absorbed, for instance, into a blood stream. Digestion is a form of catabolism; a break-down of macro food molecules to smaller ones.
New research suggests that diversity in genes implicated in immunity might have facilitated the shift from hunter-gatherer lifestyles to agriculture that occurred in prehistoric Europe over the course of around 1,500 years.
Combining discoveries in cancer immunology with sophisticated genetic engineering, Columbia University researchers have created a sort of "bacterial suicide squad" that targets tumors, attracting the host's own immune cells to the cancer to destroy it. The new work, published today in Science Advances, marks a major step forward in efforts to enlist non-pathogenic bacteria to combat cancer.
A tiny worm called the C. elegans is enabling scientists to explore the emerging theory that Parkinson's disease starts in the gut.
A vibrating capsule designed to stir the colon to action appears to double the ability for adults struggling with debilitating chronic constipation to defecate more normally and without drugs, researchers report.
Baby kangaroo feces might help provide an unlikely solution to the environmental problem of cow-produced methane.
Scientists at the State University of Campinas (UNICAMP) and the Federal University of the ABC (UFABC) in São Paulo state, Brazil, have successfully produced biogas from apple pomace, the pulpy residue remaining after the fruit has been crushed to extract its juice.
Pep-tRNAs, nascent polypeptides inside the ribosome that are covalently connected to transfer RNA, are engaged in a variety of cell processes, including gene expression, according to advances in molecular biology.
Tech companies have developed many devices that work outside the body, such as cell phones, smart watches, tablets and hundreds of others. Inside the body, though? That's obviously trickier for several reasons, but power for a device is a big one.
Engineering researchers have developed a battery-free, pill-shaped ingestible biosensing system designed to provide continuous monitoring in the intestinal environment.
A team of Duke researchers has identified a group of human DNA sequences driving changes in brain development, digestion and immunity that seem to have evolved rapidly after our family line split from that of the chimpanzees, but before we split with the Neanderthals.
An essential component of the Arctic food chain is polar fish. Along with colleagues from KU Leuven and the Alfred Wegener Institute, Sarah Maes (KU Leuven) and Fokje Schaafsma (Wageningen Marine Research) examined the diet of polar cod from the Barents Sea.
Quark and cheese are primarily casein-based in terms of protein content. The stomach’s digestion of casein results in the production of protein fragments (peptides) that have an unpleasant flavor, despite casein itself not having a bitter flavor.
By helping with digestion, supplying nutrients and metabolites, and collaborating with the immune system to ward off pathogens, gut bacteria have a significant impact on health.
The cells’ proteins contain a huge world of information that, when unlocked, can shed light on the causes of many fundamental biological occurrences. To observe the properties of individual cells at the protein level, a single-cell analysis method known as “single-cell proteomics” is used.
A stomach adult stem cell population can fulfill two distinct functions: either help with digestion under normal conditions or take the lead on injury response. S
In this interview, Shianna Hines, the Senior Field Application Scientist for cannabis and hemp-related items at PerkinElmer, talks to AZoLifeSciences about testing cannabis for impurities and contaminants.
The pancreas secretes around a cup of digestive juices per day—a mixture of molecules capable of breaking down the food people consume.
Scientists at Scripps Research and the National Institute of Dental and Craniofacial Research have discovered a special type of cell that resides in salivary glands and is likely crucial for oral health.
In recent years, proteomics research using mass spectrometry to comprehensively investigate the protein components of biological samples has become very popular.
A recent study proves that antibiotic use in the first week of birth is associated with a reduction in the number of healthy bacteria required to digest milk.
