Mathematicians from National University of Singapore and Nanjing University uncover a new mathematical method by challenging age-old assumptions of renowned mathematicians T. Aubin, A. Chang, and P. Yang Mathematically, is it possible to continuously deform a rough sphere into a perfect sphere? Under what situations can we solve the differential equations? Professor Xu Xingwang of the Department of Mathematics at National University of Singapore (NUS), along with Dr Chen Xuezhang from...

Most of us are familiar with the idea of image compression in computers. File extensions like ".jpg" or ".png" signify that millions of pixel values have been compressed into a more efficient format, reducing file size by a factor of 10 or more with little or no apparent change in image quality. The full set of original pixel values would occupy too much space in computer memory and take too long to transmit across networks. The brain is faced with a similar problem. The images captured by...

By Churchward, Matthew A Rogasevskaia, Tatiana; Brandman, David M; Khosravani, Houman; Nava, Phillip; Atkinson, Jeffrey K; Coorssen, Jens R ABSTRACT The Ca^sup 2+^-triggered merger of two apposed membranes is the defining step of regulated exocytosis. CHOL is required at critical levels in secretory vesicle membranes to enable efficient, native membrane fusion: CHOL-sphingomyelin enriched microdomains organize the site and regulate fusion efficiency, and CHOL directly supports the capacity...

By William Hageman, Chicago Tribune Jul. 6--The Adler Planetarium's recent launch of a Marshmallow Peep into space is a twist on experiments that the 10-person Adler crew has been conducting for a while. The payload on this launch, Mission 12 of the Far Horizons program, was an experiment by two students at Aurora's Illinois Math & Science Academy who wanted to measure how much brighter it is in space. Astro Peep just hitched a ride. "On any mission we like to use a video camera to...

By ALI HOWARD THINK of penthouses and you might imagine a certain decadent style of city living. In property terms, you literally can't go any higher. As Richard Gere's high-flying executive character said in the movie Pretty Woman, he always rents the penthouse because, quite simply, "it's the best". The world looks different from penthouse level; the views from the windows, of the sky and surrounding rooftops, offer an entirely different perspective on a city. For Simon Magnus,...


Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.

A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
