Il s’appelle «Clock» et vient d’être découvert au Centre for Biological Timing de la National Science Foundation, situé à la Northwestern University, Evanston(Illinois). Comme son nom l'indique, ce nouveau gène contribue au fonctionnement de «l'horloge interne» qui gouverne le rythme circadien(d’une période voisine de 24 heures) caractérisant la physiologie et le comportement des êtres vivants.  1, record 1, French, - g%C3%A8ne%20de%20l%27horloge%20interne

The GPS EOW rollover occurs every 1,024 weeks -- about once every 20 years. The GPS system calculates time by counting the number of weeks since January 6, 1980 -- up to a maximum of 1,023 weeks. At midnight between August 21-22, 1999, the GPS week "counter" will roll back to zero weeks. DOD says this will not create problems for the GPS satellites or DOD's GPS ground control center, but it could present a problem for consumers who use older GPS receivers and related applications. That's because after August 21, 1999, receivers could process satellite data incorrectly and display inaccurate information.  6, record 3, English, - end%2Dof%2Dweek%20rollover

Users of the Global Positioning System (GPS) should note that GPS does not have a Y2K problem. However, a clock overflow problem, called the "Z-count roll-over" does exist and is sometimes erroneously labeled as a Y2K problem. This clock roll-over occurs every 1,024 weeks; the first roll-over having occurred Aug. 21, 1999.  7, record 3, English, - end%2Dof%2Dweek%20rollover

[...] les récepteurs GPS subiront également la remise à zéro d’un compteur de semaines initialisé il y a 20 ans, phénomène baptisé «End of Week rollover» (EOW).

Le ministère des Pêches et des Océans rappelle à tous les navigateurs et les plaisanciers que le système de positionnement mondial par satellite(GPS) subira une remise à zéro «de fin de semaine»(EOW) à minuit, le 21 août 1999, temps universel. [...] Le système GPS permet aux utilisateurs équipés de récepteurs GPS de déterminer de façon continue leur position géographique. Ce système comptabilise les semaines depuis le 6 janvier 1980 et peut en compter jusqu'à un maximum de 1024. Par conséquent, à minuit, le 21 août, l'horloge interne du système sera remise à zéro.  2, record 3, French, - remise%20%C3%A0%20z%C3%A9ro

The pigment found by the UNC team is called cryptochrome and absorbs blue light. Sancar said there is evidence from the studies that the pigment is in the skin and brain as well as the eye. Understanding cryptochrome's connection to the body's internal clock could change how doctors treat certain illnesses. Sleep irregularities as temporary as jet lag and as serious as insomnia could eventually be addressed with a better understanding of the circadian rhythm. Sancar said a major benefit of the research could be new treatments for people who suffer from seasonal affective disorder (SAD), a major depression that comes on with the shorter days of fall and winter.  1, record 4, English, - chryptochrome
