In this video, I offer commentary on the scientific article titled "Water use and performance of Kentucky bluegrass influenced by cultivar, irrigation practices, and soil texture," published in the International Turfgrass Society Research Journal (DOI: 10.1002/its2.200).

The study evaluated two Kentucky bluegrass cultivars, Mallard and Geronimo, grown in lysimeters filled with either loamy sand or silt loam. Each setup was subjected to two irrigation levels: 40% and 80% replacement of reference evapotranspiration. The authors monitored water use and turf coverage throughout the growing season to assess drought resilience.

My commentary covers the key findings from the research, including why Mallard outperformed Geronimo under water-limited conditions, how irrigation volume influenced turf coverage more than irrigation frequency, and why soil texture had relatively minor effects on water use. I also discuss the strengths and limitations of the study design and its relevance to real-world turfgrass management.

Cardiac Cowboys

Cardiac Cowboys

The heart was always off-limits to surgeons. Cutting into it spelled instant death for the patient. That is, until a ragtag group of doctors scattered across the Midwest and Texas decided to throw out the rule book. Working in makeshift laboratories and home garages, using medical devices made from scavenged machine parts and beer tubes, these men and women invented the field of open heart surgery. Odds are, someone you know is alive because of them. So why has history left them behind? Presented by Chris Pine, CARDIAC COWBOYS tells the gripping true story behind the birth of heart surgery, and the young, Greatest Generation doctors who made it happen. For years, they competed and feuded, racing to be the first, the best, and the most prolific. Some appeared on the cover of Time Magazine, operated on kings and advised presidents. Others ended up disgraced, penniless, and convicted of felonies. Together, they ignited a revolution in medicine, and changed the world.
