POPSConverting genetic activity into music may be a way to monitor health. Together, the notes would form a harmonic chord in normal, healthy states and become increasingly out of tune as key physiological signs go awry, signaling disease. Alterovitz employed mathematical modeling to determine relationships between physiological signals. Much like the various systems in an automobile, many physiological signs work in synchrony to keep a body healthy.

POPSBio Lego -MIT & Harvard Scientists Create Living Building Blocks The self-assembly is based on "the thermodynamic tendency of multiphase liquid–liquid systems to minimize their contact surfaces", the most awesomely complicated way of saying "oil and water don't mix" possible. By preparing polyethylene microgel components and adding them to an oil/water mixture, the specially shaped bits align themselves along the spherical liquid interfaces. Applying a few seconds of UV light fixes the microgel in position and you have a ready made, biocompatible (and degradable) matrix ready for the addition of cells. Replicating the different tissue organizations of different organs becomes nothing more than a recipe book, choosing your initial microcomponents, mixture and baking time.

POPSThe Role of Light on Human Health Rea envisions "real-time light prescriptions" to help people receive or avoid light at the appropriate times. Simple measures to control when and how much circadian light we receive could help nightshift workers stay alert on the job and sleep more effectively during the day, help cure jet lag, decrease depression, and generally help everyone get a proper night's sleep. The ability to modify circadian rhythm could potentially mitigate the negative health effects that some researchers believe are brought on by disruptions to the light-dark cycle. Recent studies have found a link between health and changes in the natural circadian rhythm. The Journal of the National Cancer Institute published a series of articles, for example, that showed night shift workers had a higher incidence of breast cancer; and, last year, the World Health Organization's International Agency for Research on Cancer cited night work as a potential breast cancer risk factor.

POPSThinking ahead: Bacteria anticipate coming changes in their environment To test this idea, the researchers exposed a population of E. coli to different temperatures and oxygen changes, and measured the gene responses in each case. The results were striking: An increase in temperature had nearly the same effect on the bacterium's genes as a decrease in oxygen level. Indeed, upon transition to a higher temperature, many of the genes essential for aerobic respiration were practically turned off. To prove that this is not just genetic coincidence, the researchers then grew the bacteria in a biologically flipped environment where oxygen levels rose following an increase in temperature. Remarkably, within a few hundred generations the bugs partially adapted to this new regime, and no longer turned off the genes for aerobic respiration when the temperature rose.
