From balloons to rubber bands, things always break faster when stretched. Or do they? University of Illinois scientists studying chemical bonds now have shown this isn't always the case, and their results may have profound implications for the stability of proteins to mechanical stress and the design of new high-tech polymers."Our findings contradict the intuitive notion that molecules are like rubber bands in that when we pull on a chemical bond, it should always break faster," said...

The recent deaths of 21 polo ponies in Florida was caused by an overdose of the mineral supplement selenium, Florida's state veterinarian says. Veterinarian Thomas J. Holt says toxicology results indicate the horses had as much as 15 times the normal amount of selenium in their blood and an even higher concentration in their livers, the South Florida Sun-Sentinel reported Wednesday Officials say now that they know what killed the polo ponies, investigators must determine how the overdose...

Sedimentary rocks created more than 2.4 billion years ago sometimes have an unusual sulfur isotope composition thought to be caused by the action of ultra violet light on volcanically produced sulfur dioxide in an oxygen poor atmosphere. Now a team of geochemists can show an alternative origin for this isotopic composition that may point to an early, oxygen-rich atmosphere."The significance of this finding is that an abnormal isotope fractionation (of sulfur) may not be linked to the...

U.S. researchers say a study of sedimentary rocks created more than 2.4 billion years ago suggests the Earth had an early, oxygen-rich atmosphere. Pennsylvania State University researcher Yumiko Watanabe said rocks sometimes have an unusual sulfur isotope composition thought to be caused by the action of ultra violet light on volcanically produced sulfur dioxide in an oxygen poor atmosphere. But the team of geochemists said they can show an alternative origin for that isotopic composition...

Micro-organisms occurring naturally in coastal mudflats have an essential role to play in cleaning up pollution by breaking down petrochemical residues. Research by Dr Efe Aganbi and colleagues from the University of Essex, presented at the Society for General Microbiology's meeting at Harrogate today (Monday 30 April), reveals essential differences in the speed of degradation of the chemicals depending on whether or not oxygen is present. In aerobic conditions (where oxygen is present),...

Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. 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.'
