Carbon 14 from Cold War–era nuclear bomb tests allowed researchers to track cell birth By monitoring carbon 14 emitted from Cold War–era nuclear bomb tests, researchers found that heart muscle cells continue to divide throughout adulthood, shows a study appearing in the April 3 Science. The low-level cell renewal may eventually be exploited to treat damaged hearts, says study coauthor Jonas Frisén of the Karolinska Institute in Stockholm. The finding contradicts the belief of many scientists that the heart muscle cells sticking around until the end were present at birth. “The dogma has always been that cell division in the...

PRESS RELEASE: Los Alamos National Laboratory team of scientists prove carbon 14 dating of the Shroud of Turin wrong COLUMBUS, Ohio, August 15 — In his presentation today at The Ohio State University’s Blackwell Center, Los Alamos National Laboratory (LANL) chemist, Robert Villarreal, disclosed startling new findings proving that the sample of material used in 1988 to Carbon-14 (C-14) date the Shroud of Turin, which categorized the cloth as a medieval fake, could not have been from the original linen cloth because it was cotton. According to Villarreal, who lead the LANL team working on the project, thread samples they...

Read the entire article at Possibly the Biggest Radiocarbon Dating Mistake Ever to see it formatted, with images, notes and cited works. I asked my teacher about it but was ridiculed for not being scientific.” -- High School Student from Alaska It may well go down as the biggest radiocarbon dating mistake in history; not because there is anything wrong with the measurement process (there may not have been); not because there is anything inherently wrong with carbon 14 dating (there is not); not because of shoddy sample taking (which indeed was shoddy); not because of red flags that should...

(6) SUNSPOTS AND CLIMATE B. Geerts and E. Linacre http://www-das.uwyo.edu/~geerts/cwx/notes/chap02/sunspots.html Sunspot cycle Sunspots have a diameter of about 37,000 km and appear as dark spots within the photosphere, the outermost layer of the Sun. The photosphere is about 400 km deep, and provides most of our solar radiation. The layer is about 6,000 degrees Kelvin at the inner boundary and 4,200 K on the outside. The temperature within sunspots is about 4,600 K. The number of sunspots peaks every 11.1 years. There is a strong radial magnetic field within a sunspot, as implied in the picture, and the direction of...
