THEY COULDN'T GET THEYAH FROM HEAYAH

From Science Daily: "Researchers have discovered 2,363 new DNA sequences corresponding to 730 regions on the human genome by using new approaches. These sequences represent segments of the genome that were not charted in the reference map of the human genome." They shouldn't be granted patents but I think there would be some justice if these were within some other that were already patented, as unlikely as that might be since they would have been violating a patent to be researching them unless it was the owners themselves who were doing the sleuthing.

"A large portion of those sequences are either missing, fragmented or misaligned when compared to results from next-generation sequencing genome assemblies on the same samples," said Dr. Evan Eichler, senior author on the findings published April 19 in the advanced online edition of Nature Methods. Eichler is a University of Washington (UW) professor of genome sciences and an investigator with the Howard Hughes Medical Institute. "These findings suggest that new genome assemblies based solely on next-generation sequencing might miss many of these sites." "

In a multidisciplinary approach, Professor Yves Barral, from the Biology Department at ETH Zurich and the computer scientists Dr. Gina Cannarozzi and Professor Gaston Gonnet, from the Computer Science Department of ETH Zurich and the SIB Swiss Institute of Bioinformatics, joined forces to chase possible sub-codes in genomic information.  To read the entire article, click here

It seems that mankind is looking for smaller and smaller parts of things that were thought to be total in and of themselvesm once.  I had been taught there were 92 elements (that's how long ago I had been in school). Wikipedia writes:  "As of 2010, the table contains 118 chemical elements whose discoveries have been confirmed. Ninety-four are found naturally on Earth, and the rest are synthetic elements   (too unstable to be found naturally) that have been produced artificially in particle accelerators. Elements 43 (technetium), 61 (promethium) and all elements greater than 83 (bismuth), beginning with 84 (polonium) have no stable isotopes. The atomic mass of each of these element's isotope having the longest half-life is typically reported on periodic tables with parentheses.[3] Isotopes of elements 43, 61, 93 (neptunium) and 94 (plutonium), first discovered synthetically, have since been discovered in trace amounts on Earth as products of natural radioactive decay processes."

The whole scientific process and its rapid burgeoning is fascinating and mind-boggling at the same time. Only a few decades back, a person of  minor, elevated intelligence could keep track of all these new findings. It is getting harder and harder to conceptualize and stay current with changes in some of the things science has found without specializing in a particular field.  The 'jack-of-all-trade' is becoming extinct. We amateurs who used to have a reasonable knowledge on many technical, technological, medical, as well as rich accumulated resources on many subjects, now realize all things need a more in-depth study, limiting those who are unwilling to focus just on one area of expertise.  We are no long 'jacks-of-all-trades' but we can be assured of being 'masters of none'.
