In combination with other historical, molecular, agronomic, and crossing data, these findings support a hypothesis of multiple early introductions of both Andean and Chilean germplasm to the Canary Islands and to Europe, said Dr. David Spooner, co-author of the Cro...DOE JGI sets 'gold standard' for metagenomic data analysis

... Genetic adaptation The nematode was exposed to a combination of different pH and copper values. As well as their individual effects, the pH and the copper levels in the soil can exert a synergistic effect on the nematode population. Unexpectedly fast adaptation was observed and considerable genetic changes too...Toxoplasmosis infection trick revealed by scientists

This means that the team have a more detailed picture than ever before of exactly how the parasite recognises and at...'Short-circuit' found in ocean circulation
...tant part of it works The research shows that a combination of rapid mixing across and rapid movement along density surfaces creates a 'short-circuit' in the overturning circulation, meaning it is more concentrated in this part of the Southern Ocean. The researchers made use of a unique signal - the spread...Global heartbeat control suggests therapy for beating heart failure
