FINDINGS: Whitehead Institute researchers have determined that heat shock protein 90 (Hsp90) can create diverse heritable traits in brewer's yeast (Saccharomyces cerevisiae) by affecting a large portion of the yeast genome. The finding has led the researchers to conclude that Hsp90 has played a key role in shaping the evolutionary history of the yeast genome, and likely others as well. RELEVANCE: Over the past several years, Whitehead Member Susan Lindquist has built the case that heat shock...

Scientists watch as E. coli bacteria evolve heat resistance under stress Scientists in Munich report evidence that high concentrations of the molecular "chaperone" proteins GroEL and GroES -- intracellular machines that can stabilize folding proteins under stress -- play a critical role in increasing the maximum temperature at which E. coli bacteria can grow. Massively and permanently elevated levels of the GroE proteins were found in bacteria adapted, step-wise over a period of years, for...

Like yoga for office drones, cells do have coping strategies for stress. Heat, lack of nutrients, oxygen radicals "“ all can wreak havoc on the delicate internal components of a cell, potentially damaging it beyond repair. Proteins called HSPs (heat shock proteins) allow cells to survive stress-induced damage. Scientists have long studied how HSPs work in order to harness their therapeutic potential.

By Galindo, Federico Gomez Sjoholm, Ingegerd; Rasmusson, Allan G; Widell, Susanne; Kaack, Karl We review and analyze the possible advantages and disadvantages of plant-stress-related metabolic and structural changes on applications in the fruit and vegetable processing industry. Knowledge of the cellular and tissue transformations that result from environmental conditions or industrial manipulation is a powerful means for food engineers to gain a better understanding of biological systems...


Word of the Day
monteith
  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
  • A kind of cotton handkerchief having white spots on a colored ground, the spots being produced by a chemical which discharges the color.
This word is possibly named after Monteith (Monteigh), 'an eccentric 17th-century Scotsman who wore a cloak scalloped at the hem.'
