The Symmetries of Things |
 |
Every day we are surrounded by symmetric objects and patterns. From furniture to flooring, symmetry is the rule. In art, symmetry is pleasing to the eye, and the intricacies of extremely symmetric patterns can entrance an audience. In architecture, symmetric designs are attractive for yet another reason – repetition of a design element means re-use, which ultimately requires less planning and testing. In manufacturing, it is simpler, cheaper and more efficient to repeat a pattern at regular intervals. Even Nature has reasons to use symmetry in her work. John H. Conway and William Thurston adapted Murray MacBeath’s mathematical language for discussing symmetry. Now, the symmetries of a pattern can be defined by a single symbol that we call its signature. With some practice, almost anyone with some knowledge of high-school geometry can read this signature and identify the symmetries it describes.
John Conway is the John von Neumann Professor of Mathematics at Princeton University. He is one of the most influential mathematicians working in a wide variety are areas: combinatorial game theory, geometry, geometric topology, group theory, number theory, algebra, algorithmics and theoretical physics. He received numerous awards including the Berwick Prize and was elected a Fellow of the Royal Society. He was the first recipient of the Pólya Prize and won the Nemmers Prize in Mathematics. He is also known for the invention of the Game of Life.

How Medical Sequencing and Network Biology Will Enable Personalized Medicine |
 |
Applications of next-generation nucleic acid sequencing technologies will lead to the development of precision diagnostics. Terabyte-scale, multidimensional data sets derived from these methods will be used to reverse engineer the specific disease pathways that underlie individual patients’ conditions. Modeling and simulation of these pathways in the presence of virtual drugs, and combinations of drugs, will identify the most efficacious therapy for precision medicine and customized care. The practice of medicine will routinely employ network biology analytics supported by high-performance computing.

Why We Get Fat: Adiposity 101 and the Alternative Hypothesis of Obesity |
 |
Since the 1950s, overweight and obesity have been perceived as “energy balance” disorders, caused specifically by overeating and sedentary behavior. Virtually all research in obesity and related fields is predicated on this energy balance paradigm, as is the conventional wisdom on how to cure and prevent obesity: consume fewer calories than expended and we will become lean. Reasonable as it seems, this prescription has little to no efficacy, suggesting the possibility that the underlying hypothesis is incorrect.
What’s the alternative? Prior to World War II, European clinicians argued that to understand obesity, we have to think of it as fundamentally a disorder of excess fat accumulation, not energy balance. A defect in the regulation of adipose tissue metabolism causes the accumulation of excess fat, and positive energy balance is an effect, not a cause. By the 1960s, it was clear that fat accumulation is fundamentally regulated by the hormone insulin, which in turn is secreted primarily in response to the carbohydrates in our diet. Thus, a reasonable hypothesis of obesity and overweight is that these conditions are caused not by excess calorie consumption, but by the quantity and quality of carbohydrates consumed.
