POPSCommonly overused words "When you write, use the most precise word for your meaning, not the word that comes to mind first. Consult this thesaurus to find alternatives for some commonly overused words. Consult a full-length thesaurus to find alternatives to words that do not appear here. Keep in mind that the choices offered in a thesaurus do not all mean exactly the same thing. Review all the options, and choose the one that best expresses your meaning."

POPS'bizarre mix of mammal, bird and reptile, with very complex sexuality' The fact that the animal has five X and five Y chromosomes is "the weirdest thing about a very weird animal," said Ewan Birney, a co-author on the paper, based at the European Bioinformatics Institute, near Cambridge. "In theory it means there are 25 possible sexes, though in practice that doesn't happen."

POPSSex, lies and some existential questions.. :-) So many orchids treat their pollinators so nastily, with false promises of food and sex or the occasional dunking of insect visitors into bucket-shaped petals full of liquid, that naturalists have puzzled over the relationship for more than a century. Darwin was so consumed by the odd interactions that after “The Origin of Species,” his next book was an entire volume on the subject, “The Various Contrivances by Which Orchids Are Fertilized by Insects.”

POPSRichard Dawkins' jaw-dropping talk on our bizarre universe Richard Dawkins discusses the question of limits on human understanding. As a species we evolved to cope with the world within a particular range of physical dimensions. These determine our common sense view of the world. How far can the plasticity of our brains transcend this limitation?

POPSThe DNA Mystery: Scientists Stumped By "Telepathic" Abilities Even so, research published in ACS’ Journal of Physical Chemistry B, shows very clearly that homology recognition between sequences of several hundred nucleotides occurs without physical contact or presence of proteins. Double helixes of DNA can recognize matching molecules from a distance and then gather together, all seemingly without help from any other molecules or chemical signals. This recognition effect may help increase the accuracy and efficiency of the homologous recombination of genes, which is a process responsible for DNA repair, evolution, and genetic diversity. The new findings may also shed light on ways to avoid recombination errors, which are factors in cancer, aging, and other health issues.
