Aquaporins - the perfect water filters of the cell
...hly efficient, yet selective water transport, that excludes
permeation of other molecules, is of central importance. As filters of the cell, aquaporins prevent the loss of e.g. sugar molecules or ions. Despite this high degree of selectivity, aquaporins reach a remarkable efficiency of up to three billion wat...

it from involvement in the end-Triassic extinction, but it is within estimates for the Norian-Rhaetian boundary. Other options include the onset of massive volcanism associated with the Central Atlantic magmatic province created when the supercontine...
Major mutations, not many small changes, might lead way to new species
... on the other hand, has a deep, tubular shape that excludes
bees but is easily probed by the slender beaks of hummingbirds, and has red or deep yellow-orange petals, colors bees can't see. These and other differences make the species of monkeyflowers distinct and nearly eliminates crossbreeding in the wild. ...
Nutrient-poor oceans generate their food 'hot spots'
...er accumulates owing to greater sun exposure. This excludes
the possibility of nutrients ascending from the deep cold waters by mixing. In the convergence zones produced by wave movements, there would not be any new production of phytoplankton as had been suggested, but rather an accumulation of floating orga...

the vast majority of repetitive, gene-poor DNA, Cold Spring Harbor researchers have now achieved a dramatic shortcut to sequencing the genes of corn. The approach should provide a similar boost to the sequencing and comparative analysis of other geno...
