Magic, Mystery, and Matrix
1124 NOTICES OF THE AMS VOLUME 45, NUMBER 9 I n the twentieth century, the quest for deeper understanding of the laws of nature has largely revolved around the development of two great theories: namely, general relativity and quantum mechanics. General relativity is, of course, Einstein’s theory according to which gravitation results from the curvature of space and time; the mathematical framew...
متن کاملThe magic and mystery of miR-21.
MicroRNAs (miRNAs) are potent regulators of mRNA stability and thereby protein expression. As such, miRNAs have become of interest as possible therapeutics and/or therapeutic targets. In this context, small complementary miRNA sequences known as antagomirs could be used to inhibit miRNA activity, while miRNA mimics could confer gain-of-function activity. However, a note of caution is sounded by...
متن کاملThe magic angle: a solved mystery.
We resolve the long-standing mysterious discrepancy between the experimental magic angle in EELS--approximately 2theta(E)--and the quantum mechanical prediction of approximately 4theta(E). A relativistic approach surpassing the usually applied kinematic correction yields a magic angle close to the experimental value. The reason is that the relativistic correction of the inelastic scattering cro...
متن کاملThe magic and mystery of microRNA-27 in atherosclerosis.
Atherosclerosis (As) is now widely appreciated to represent a chronic inflammatory reaction of the vascular wall in response to dyslipidemia and endothelial distress involving the inflammatory recruitment of leukocytes and the activation of resident vascular cells. MicroRNAs (miRNAs) are a group of endogenous, small (~22 nucleotides in length) non-coding RNA molecules, which function specifical...
متن کاملThe magic of medicine.
There are many wonderful museums in Jerusalem, but one of my favourites is the Bible Lands Museum. Its collection includes historical artefacts from all around the ‘‘fertile crescent’’—the great swathe of land from Persia to Egypt that was the source of many ancient civilisations, and gave birth to some of the world’s great religions. Currently there are two special exhibitions there. One is ce...
