Microbes inhabit just about every part of the human body, living on the skin, in the gut, and up the nose. Sometimes they cause sickness, but most of the time, microorganisms live in harmony with their human hosts, providing vital functions essential for human survival. For the first time, a consortium of researchers organized by the National Institutes of Health has mapped the normal microbial makeup of healthy humans, producing numerous insights and even a few surprises.
MIT researchers have developed a new fuel cell that could be used to power brain implants in coming years [1]. Just like human cells, the fuel cells run on glucose, which is the most common sugar in nature and in the human body. Human cells derive energy from glucose through a process called oxidation — a part of metabolism — that takes electrons from the glucose and passes those electrons from enzyme to enzyme in the cell, generating the energy molecule adenosine triphosphate (ATP).
Most acute wheezing episodes in preschool children lead to airway dehydration. Together with other factors, airway dehydration causes the body to have trouble clearing mucus. These children do not respond well to available treatments. A new study published in the journal Pediatrics evaluated the effect of administering inhaled hypertonic saline to wheezing preschool children, which promotes airway hydration and thus mucus clearance [1].
In a recent communication with the Corn Refiners Association (CRA), the Food and Drug Administration (FDA) declined to authorize the use of the term corn sugar for high-fructose corn syrup (HFCS). The CRA has been troubled in recent years by the increasingly negative image of HFCS, due in large part to amassing research that suggests the body may metabolize it differently than table sugar [see, for instance, 1,2]. They’ve responded to this negative press by launching a campaign called Sweet Surprise designed to cast HFCS in a positive light, and have also requested that the FDA allow product manufacturers to list HFCS as corn sugar on packages.
Men’s Health Week is celebrated each year as the week leading up to and including Father’s Day. This year, Men’s Health Week runs from June 11th–17th. It is observed as part of the larger Men’s Health Month, which is celebrated during the month of June with screenings, health fairs, media appearances, and other health education and outreach activities.
