Computer model predicts outcome of DNA shuffling
...ide any diversity and the reassembly algorithm now excludes them. "The program reveal these trends," says Maranas. "You can explore many what if scenarios before expending time and resources in the lab. These scenarios may include different fragment lengths, annealing temperatures or even the selectio...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...GSA release 02-55: Dec. Geology & GSA Today media highlights
...impact. The age of the enormous Manicouagan Crater excludes 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...Less is more: New technology captures gene-rich DNA segments
...ntly developed that captures gene-rich regions and excludes 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...Scientists discover way to streamline analysis of maize genome

The methylation filtering technique excludes hyper-methylated DNA sequences (a characteristic o...t the University of Georgia's genetics department, excludes highly-repetitive DNA sequences by using a different method that separates DNA segments into "low-co...Feeder-free system for maintaining pluripotency in embryonic stem cells pioneered

A marine animal belonging to the gastropod mollusk group is the original source of the compound now in use in the new feeder-free system. The natural mol...
