Science magazine

This question, which freezes first, hot water or cold water, is a favorite of popular science magazines. This discussion is taken from the web site http //math.ucr.edu/home/baez/physics/General/hot water.html. Sir Francis Bacon, Descartes and even Aristotle are said to have remarked on it. There are five factors that can make the hot water freeze faster than expected. 

Pheromones have been defined as substances released by an individual into the external environment which precipitate a particular reaction in a conspecific (Karlson and Liischer 1959). Pheromones are used by species in a variety of phyla (see e.g. McClintock, Jacob, Zelano and Hayreh 2001), and there exist many examples of pheromone-mediated behaviour in a wide range of mammals, particularly in relation to mating behaviour and maturation (see e.g. Vandenbergh 1983). In humans however, the question of whether pheromones influence behaviour was recently listed by Science magazine as one of the top 100 outstanding questions (Anon 2005). A recent review of behavioural and anatomical studies relating to the function of pheromones in human interactions concluded that while a small number were unambiguously supportive , none seemed ultimately conclusive (Hays 2003).

Science magazine had printed a summary of a pharmacology conference where a prominent scientist, Dr. David Nachmanson, had expounded his formulation of the mode of action of cholinesterase inhibitors. His list of references included a study published earlier by a Dr. VanSint. Fred and I sensed the opportunity to shake up our beloved Chief Scientist a little bit. We forged a dissenting view addressed from Van to Dr. Nachmanson, fdling it with preposterous assertions. We typed it carefully, and signed it Van M. Sim, M.D. (as distinct from Dr.VanSinf ). 

If you look at Science magazine when it comes out tomorrow, you may not be too happy with its comments about BZ. I wanted you to know about it ahead of time, because I appreciated your honesty when we talked. ... 

I had indeed been honest and it was certainly true that I liked to read Science magazine. (By now, in fact, you must think Science is the only magazine I ever read )... 

The Shaker potassium channel did not yield crystals for the first potassium ion channel X-ray crystallographic structure. Rather, it was the prokaryote bacterium Streptomyces lividans, abbreviated as the KcsA K+ channel, that first produced crystals suitable for crystallography. This structure, published in 1998 by MacKinnon s group in Science magazine, was received with great praise from the scientific community. It was known at that time that the amino acid sequence of KcsA was similar to that of other K channels, including vertebrate and invertebrate voltage-dependent K (Kv) channels (such as the... 

The Cech group described an X-ray crystallographic structure of the group I intron from Tetrahymem thermophila in a Science magazine research article published in 1998 (PDB IGRZ). The 5.0-A resolution crystal structure included 247 nucleotides comprising most of the Tetrahymena thermophila intron. At this resolution, clear density for the ribozyme backbone was seen, and stacked bases were visualized as continuous tubes of electron density. 

Cytochrome c oxidase (CcO) has been characterized as a proton pump (see, for instance, M. Saratse s 1999 Science magazine article ), although CcO... 

According to some journalists, Einstein s brain was saved at his son s request. Other sources suggested that Einstein himself wanted his brain saved, but Einstein s estate denies this. Contrary to what you might think, research on Einstein s brain did not take place until 30 years after his death—perhaps because no one could agree on how to cut up this priceless object. In 1978, Science magazine suggested that the delay was never satisfactorily explained. 

In 1981, Science magazine again asked Dr. Harvey if he had finally finished his research on Einstein s brain. Harvey s response was, No concrete plan. I have my ideas about it but they have not solidified. Science magazine wrote, Harvey possesses small fragments of the brain, but declines to say exactly where they are now stored. Einstein s estate, he says, has no interest in them. ... 

Nitric oxide (NO) has profound biological significance and was named Molecule of the Year by Science magazine in 1992 (157). This also has resulted in the appearance of an increasing number of experimental and theoretical studies on metal-NO complexes (158-161). 

The authors would like to thank Drs. Joseph J. Cooney and Laurence E. Hallas of the Chesapeake Biological Laboratory and Dr. Jon M. Bellama of the Department of Chemistry (all of the University of Maryland) for providing copies of unpublished manuscripts. The authors are indebted to Drs. Thomas D. Coyle, Warren P. Iverson, and Greg J. Olson, all of the National Bureau of Standards, for valuable comments and discussions. The authors also thank Dr. William H. Zoller (Department of Chemistry, University of Maryland) and Science magazine for granting copyright release. 

The years 2000-2003 have seen a great deal of progress made in the field of molecular electronics. Science Magazine named molecular electronics the breakthrough of the year in 2001.30 In the following sections we will review the more recent work. 

Reports in Science magazine and The Journal of the American Medical Association have raised the greater fear that MDMA use necessarily causes neurotoxicity. As might have been expected, this possibility has been highly... 

The American Association for the Advancement of Science (AAAS) is the world s largest scientific society and the publisher of Science magazine. It is an international nonprofit organization dedicating to advancing science.
