Your microbiome is the collection of all the microbes (bacteria, viruses, fungi, etc.) that live on and in you. It profoundly affects your health and, studies increasingly show, the health of your children.

Past research in mice has found that maternal gut bacteria play a role in offspring behavior and placental growth during pregnancy. Now scientists have looked at paternal influences.

A new study reports that altering the gut microbiome of male mice negatively affected the health and lifespan of their offspring through epigenetic changes in sperm. Offspring of males whose gut microbiome had been disrupted by antibiotics suffered from impaired gestation and metabolic dysfunctions.

Stories for the Waiting Room

There's a right way and a wrong way to measure blood pressure. The latter can lead to overdiagnosis. If you're sitting on a paper-covered table when your blood pressure is taken, that's the wrong way. You should be seated in a chair with your arm supported on a desk or other surface, keeping the cuff aligned with your heart.

Measuring blood pressure with a patient's arms in their laps or hanging by their sides tends to overestimate blood pressure by as much as 4 mmHg for the top number (systolic, or when blood pumps) number and almost 7 mmHg for the bottom number (diastolic, or when the heart rests between beats), according to new research.

Study authors estimated that improper arm position could mean 16% of U.S. adults, or 40 million Americans, may be mistakenly diagnosed with hypertension using a cutoff of 140 mmHg and higher, and 22%, or 54 million people, would be misclassified using the lower cutoff of 130 mmHg. That could be the difference between a prescription for a hypertension-lowering medication or a recommendation to make lifestyle-only changes, reports STAT.

Hypochondriac's Guide

Cornu cutaneum are hard, conical projections made from compacted keratin (most notably the stuff of fingernails and hair) that grow out of the skin. They are also known as cutaneous horns because, well, they can resemble an animal's horn, but they may appear anywhere on the body.

Typically, they are benign tumors, often prompted by overexposure to the sun, but sometimes they emerge from premalignant or malignant skin lesions. They are not true horns because they do not grow directly from the skull. One exception: Rhino horns are also hardened keratin growing from the skin.

Medical History

This week in 1982, Dr. William C. DeVries replaced the diseased heart of 61-year-old Barney Clark with the Jarvik-7, the first permanent artificial heart ever used for a human patient. Clark survived for 112 days, dying from complications. Only four other patients received the Jarvik-7 heart over the following three years. The second, William Schroeder, lived 620 days, dying in 1986 at age 54. Other patients received the artificial heart only as a temporary device while awaiting heart transplants.

Ig Nobel Apprised

The Ig Nobel Prizes celebrate achievements that make people laugh, then think. A look at real science that's hard to take seriously, and even harder to ignore.

In 2001, the Ig Nobel Prize in economics went to researchers at the University of Michigan and the University of British Columbia for their conclusion that people find a way to postpone their deaths if that qualifies them for a low a lower rate on the inheritance tax.
