Seemingly futile cycles are not thermodynamically futile

Scientists discover an on/off switch for aging cells The switch controls the growth of telomeres, the timekeepers of cells September 19, 2014 Excerpt: Understanding how this “off” switch can be manipulated–thereby slowing down the telomere shortening process–could lead to treatments for diseases of aging (for example, regenerating vital organs later in life).” My comment: Seemingly futile thermodynamic cycles of protein biosynthesis and  degradation appear to be confusing. I’m somewhat certain that the folks at Salk realize that cycles of biophysically-constrained…

How Do You Know When You’ve Found Them All? A Question That Applies To Beetles and Cancer Genes Alike by Carl Zimmer Conclusion: “Cancer biologists and beetle experts are not all that different when you think about it. They walk the same foggy road together, a long way from the end.” My comment: Only the cancer biologists and beetle experts who believe in mutation-driven evolution are walking a road together. It’s not a foggy road. It’s brain fog that makes them similar.…
