Inflammatory bowel disease (IBD) affects more than 1.4 million people in the United States alone. While IBD is often confused with irritable bowel syndrome, the two conditions are not the same. This isn’t to diminish irritable bowel syndrome, which can cause serious gastrointestinal discomfort. It simply doesn’t lead to the same visible inflammation and damage in the intestines that we usually see in IBD. IBD manifests in various forms, but the two most common—and well-known—types are Crohn’s disease and ulcerative colitis. Cases of Crohn’s disease, in particular, are increasing, supporting the need to find an effective course of treatment for the condition.

Each year, almost 1.3 million people in the United States die in road crashes, with an astonishing average of 3,287 deaths each day. Unsurprisingly, a large number of these fatal accidents occur at night, and though extraneous factors such as driving speed, alcohol use and sleep deprivation contribute to the danger of driving at night, researchers do agree that “low luminance plays a major role in this effect.”

You might be surprised to learn that burn injuries are the most common type of skin trauma, with approximately 130,000 individuals in the United States hospitalized each year due to burns. Though the majority of these burn victims will live, 4,500 will die from the burns themselves, and 10,000 will die of burn-related infections. Reducing the number of deaths, and burn-related infections in particular, will require the ability to quickly restore the skin’s protective and metabolic functions after burn trauma.

While the global demand for meat has been steadily increasing, the reliance upon animals to meet this demand is not without complications. In fact, our world’s collective love of meat might one day result in “increased environmental pollution, energy consumption, animal suffering, and the proliferation of animal-borne disease.” How can we avoid such a future? According to a Times editorial, synthetic meat products created in the laboratories of food and beverage companies instead of originating on a farm will come to dominate our supermarkets. Still, current efforts in the development of synthetic meat and other food items are in infancy. In order to accelerate the field, more information about precursor cells, how the cells can be grown in bioreactors and the types of additives and preservatives to add remain a working challenge.
