BEACH RESTORED BY ARTIFICIAL RENOURISHMENT

Epithelia restored by healing waves

A delay in cyclin-dependent kinase activity prevents meiotic chromosomes from prematurely attaching to spindle microtu-bules, Davydenko et al. report. In somatic cells, the mi-totic spindle assembles and forms stable attachments to the kinetochores of sister chroma-tids in a matter of minutes. In mammalian oocytes undergoing meio-sis I, however, multiple microtubule-organizing centers take seve...

BACKGROUND During the last decade, results of surveys of adults showed an increase in sun protection knowledge, a slight decline in the attitude that having a tan was healthy, widespread sunscreen use as the principal method of solar protection, and an increase in sunburning. METHODS During the summer of 1996, observers recorded the sun protection activities of 352 family groups as they arriv...

Sediment Recycling: Marsh Renourishment Through Dredged Material Disposal

Anthropogenic Renourishment Feedback on Shorebirds: a Multispecies Bayesian Perspective

22 In this paper the realized niche of the Snowy Plover (Charadrius alexandrinus), a 23 primarily resident Florida shorebird, is described as a function of the scenopoetic and 24 bionomic variables at the nest-, landscape-, and regional-scale. We identified some pos25 sible geomorphological controls that influence nest-site selection and survival using data 26 collected along the Florida Gulf c...

Frankenstein restored

When Ilya Prigogine carried off the Nobel Prize for network thermodynamics the science editor of a great English daily newspaper was on hand with guidance for the perplexed: “Professor Prigogine,” he explained, “is an expert on the chemical make-up of human beings.” Frankenstein, for once, did not rear his head, but he is no stranger to the headlines. As Jon Turney reveals in his dense treatise...
