New nano-sensor speeds up DNA detection

New test speeds detection of E. coli.

The biochemical effects of CHIP have been studied in C3H mice with and without transplanted mammary tumour. The maximum tolerated dose of CHIP was first determined by lethality and intestinal crypt assays to be 40mgkg-' and this dose was used to assay the time course of gastric distension and the pattern of drug distribution. A high level of CHIP uptake was found in liver as well as kidney. For...

The Effects of Nano In2O3 and ZnO on the CO Gas Detection of the SnO2 Sensor

The pellet-type SnO2 sensor was synthesized by the solid state method and the effects of additives such as nano ZnO (1-12 mol %) and nano In2O3 (1-10 mol %) on the CO gas sensitivity of sensor were investigated. The optimum sintering temperature was chosen 800°C because of the porosity content of the samples. The phase analysis and microstructure of the samples were studied by x-ray diffraction...

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 ...
