The word analogy is a synonym of likeness, resemblance, similitude, or affinity and involves two concepts being placed side by side, as in a comparison [1]. The workings of nature and those of human societies are amenable to such analogous comparison-even though the evolution of the natural world obviously spans millions of years [2], while human societies are much younger, relatively puppies by comparison. This article considers two interesting examples from these two realms that show remarkable similarities (possibly a result of sheer chance), i...

"Moderation in all things" is a popular saying that many of us have heard all our lives. Still, a good number of people seem to have forgotten the sentiment behind this advice. Instead of looking for the good that exists within the bad and the bad that dwells within the good, people are choosing to line up behind one extreme or another. Nuances are being ignored in favor of strong positions on either side of the middle. This has led inevitably to polarization, partisanship, and balkanization in our society...

Although asthma has been around since Hippocrates' time, more people are being diagnosed with the disease than ever before. Over the last 20 years, the global burden of asthma has increased by almost 30%, as more than 235 million people-most of them children-cope with the breathlessness and wheezing characteristic of the disease. In particular, cases have spiked in China and India, where pollution is reported to sometimes be deadly. Researchers with the Health Effects Institute, a Boston-based nonprofit that studies the health effects of pollution, recently reported that air pollution in India and China alone contributed to more than half of the four million deaths worldwide due to air pollution in 2015...

Although the overall incidence of colon cancer has been falling over the past few decades, a pair of recent studies revealed a startling trend. In February 2017, researchers published a report showing that colon cancer rates were rising among younger adults. Some skeptics suggested the spike might simply reflect earlier detection and not necessarily represent a real increase in the disease. But a follow-up study found that Gen-Xers and millenials aren't just getting cancer diagnoses earlier; they are dying from colon cancer at slightly higher rates than in previous decades...

In the science-fiction classic Fantastic Voyage [1], a shrink-ray zaps a submarine and the crew within it, and the resulting microscopic vehicle ventures inside a human body to destroy a blood clot and save a prominent patient's life. While that scenario remains in the realm of make-believe, it may not be long before micro- and nanoscale robots can navigate a person's blood vessels and execute a medical task, such as the targeted delivery of drugs or even the performance of some medical procedures.

Around 6 p.m. each evening, the streets of Boston's suburbs come alive with the physically fit and those aspiring to be. They are runners, bikers, walkers, and scooter riders of all different body shapes and ages who would seem to have little in common except one thing-an electronic band wrapped around their wrist. For many of these people, it's hard to imagine life without the daily nagging from a personal health device to meet their daily prescript of 10,000 steps.

In the 16th century, Paracelsus-the father of modern toxicology-wrote that "all things are poison and nothing is without poison; the dose alone makes a thing not poison." While it's conceivable that too much of a good thing, such as water or oxygen, could be fatal, the opposite-that smaller quantities of a bad thing might be beneficial-may be harder to believe. But four centuries after Paracelsus shared this idea, two researchers decided to apply the more counterintuitive notion of Paracelsus' dogma for a notoriously toxic chemical: carbon monoxide (CO)...

When Leonard D'Avolio (Figure 1) was working on his Ph.D. degree in biomedical informatics, he saw the power of machine learning in transforming multiple industries; health care, however, was not among them. "The reason that Amazon, Netflix, and Google have transformed their industries is because they have embedded learning throughout every aspect of what they do. If we could prove that is possible in health care too, I thought we would have the potential to have a huge impact," he says.

Of the key technologies listed as "ready to propel industries and transform our world" in the 2017 report Top 50 Emerging Technologies: Growth Opportunities of Strategic Imperative, most fall under the scope of biomedical engineering (BME). Issued by the major market research and analysis company Frost and Sullivan [1], the report's findings are no surprise to the researchers, clinicians, and others who are heavily invested in this field.

The relationship among cardiac pacemakers is characterized by the fact that one pacemaker is usually dominant and all the others are subsidiary. The sinoatrial node acts as the dominant pacemaker, and all other potential pacemaker tissues are discharged by a conducted impulse before their respective diastolic depolarizations attain threshold. These pacemakers are called subsidiary to emphasize the fact that, under normal circumstances, they are engaged in conducting impulses, but, under abnormal circumstances, they may become actual pacemakers...

While the field of engineering as a whole is largely male-dominated, biomedical engineering (BME) is one area poised to overturn this trend. Women in the United States were awarded only 20% of all engineering B.S. degrees in 2015; in BME, however, 40.9% of the degree recipients were women. This stands in stark contrast to the more traditional fields of mechanical and electrical engineering, where women were awarded just 13.2% and 12.5% of B.S. degrees, respectively. This trend toward more female participation in BME continues at both the M...

The first spark of my desire to become a cardiologist came, believe it or not, in a third-grade art class where I was asked to draw and color the circulation of blood as depicted by 16th-century English physician William Harvey. This task enraptured me-seeing that something so beautiful could work so flawlessly. So, many years later, I remain intrigued by cardiac transplantation, the subspecialty in which I ultimately chose to anchor my career as a physician scientist. Each day I live in awe of the fact that you can remove someone's organ, place it in another, and still have that organ work beautifully, most of the time...

If CSI and those other police procedural TV shows are to be believed, criminals don't have a chance. A finger smudge on a light switch, a flake of skin, or a sweat-stained fiber is all the information an investigator needs to positively identify the perpetrator and put him or her behind bars.

"The future of medicine is in your smartphone," proclaimed an eminent medical researcher in a 2015 Wall Street Journal essay. In a sense, that future has already arrived, judging from the proliferation of apps and medical devices now connected to smartphones. One 2015 industry study identified more than 165,000 health-related smartphone apps available from the Google Play Store and Apple iTunes. But to what extent does this technology lead to improved patient outcomes? That question is one for evidence-based medicine, to be answered by clinical trials and systematic reviews by medical experts...

Pulmonary arterial hypertension is a rare and potentially life-threatening disorder. But when prominent entrepreneur Martine Rothblatt (Figure 1), founder of Sirius radio, learned in the 1990s that her daughter had been diagnosed with this little-known condition and given only three months to live, she refused to accept that grim prognosis. Instead, Rothblatt transformed her life.

Water on Earth-in our oceans, rivers, lakes, and wetlands-might seem plentiful, but water that is clean and safe enough to drink actually isn't so abundant. Nearly one in ten people still lacks access to safe water worldwide, according to the World Health Organization. In some of the world's most remote and impoverished communities, people live with no taps, showers, flushing toilets, or nearby springs, making it difficult to keep water supplies safe from bacteria, chemicals, and particulates. Moreover, access to clean drinking water isn't just a problem in the developing world; groundwater in developed countries is typically used far more quickly than it is being replenished...

On a balmy evening in mid-May 2017, Chris Cornell, the legendary head of the internationally renowned rock band Soundgarden, strummed his last chord at the Fox Theater in Detroit and headed to the MGM Grand Hotel. According to the police report, he swallowed a few tablets of the antidepression drug Ativan in his room and called his wife. "I'm just tired," he said and hung up the phone. Later that night, at the request of his concerned wife, his bodyguard forced open Cornell's door to discover him on the bathroom floor, an exercise band tied around his neck...

The human gut is home to an abundant and diverse community of microbes–each of us carries roughly 100 trillion, representing more than 1,000 different species. The composition of one?s gut microbiota is individually specific, dynamic, and influenced by genetics, diet, age, metabolism, medication use, stress, and geography. These bacteria perform a range of necessary and beneficial functions, including breaking down our food and supporting our immune systems.
