Speeding Up Computers

For over thirty years until 2004-5 the speed of processors followed the Moore’s Law and was exponentially increasing. Approximately every 18 months processors speed doubled. This rapid and steady progress was very economically satisfying. It was enough to wait several months for new processor generation without the need for redeveloping software. However shortly after the electronic technology ...

Genome Evolution: Recombination Speeds Up Adaptive Evolution

Mutual interference among linked genetic sites subject to selection may reduce the level of adaptation. A recent study detected this effect using data on protein sequence evolution and codon usage in Drosophila.

Visual Speech Speeds Up Auditory Identification Responses

Auditory speech perception is more accurate when combined with visual speech. Recent ERP studies suggest that visual speech helps 'predict' which phoneme will be heard via feedback from visual to auditory areas, with more visual salient articulations associated with greater facilitation. Two experiments tested this hypothesis with a speeded auditory identification measure. Stimuli consisted of ...

Eating the competition speeds up invasions.

Many introduced species engage in intraguild predation (IGP), the consumption of species with which they compete for shared resources. While the factors influencing local persistence of IG predator and prey species are well-understood, using these factors to predict the invasion speed of an introduced IG predator has received less attention. Existing theory predicts that native competitors slow...
