Gene behind ‘evolution in action’ in Darwin’s finches identified

Scientists from Princeton University and Uppsala University in Sweden have identified a specific gene that within a year helped spur a permanent physical change in a finch species in response to a drought-induced food shortage. The findings provide a genetic basis for natural selection that, when combined with observational data, could serve as a comprehensive […]

An abandoned probe just discovered something weird about the atmosphere of Venus

The fiery hellscape that keeps on giving.DAVID NIELD 21 APR 2016 Just when we’d all forgotten about the second-closest planet to the Sun – what with Planet Nine taking up all our attention – an old, abandoned probe has come through with some weird data from the atmosphere of Venus.

Bird genome contains ‘fossils’ of parasites

In rare instances, DNA is known to have jumped from one species to another. If a parasite’s DNA jumps to its host’s genome, it could leave evidence of that parasitic interaction that could be found millions of years later – a DNA ‘fossil’ of sorts. An international research team led from Uppsala University has discovered […]

A nossa vida toda não passa de um filme !

Cientistas da École de Lausanne decidiram investigar se por detrás da percepção consciente do que se passa à nossa volta todos os dias existe um processamento ‘inconsciente’ que só vem à luz da nossa consciência após estar completo. As operações atómicas que tratarão de processar os constituintes de qualquer estímulo/imagem que desperte a nossa atenção […]
