Scientists have shed new light on a 500-million year old mystery. Some 500 million year-old fossils of the Burgess Shale in Canada, discovered over a century ago, still provide one of the most remarkable insights into the dawn of animal life. The beautiful silvery fossils show the true nature of the life of that time, [...]

Astronomers have uncovered a type of galaxy that represents a missing link in our understanding of galaxy evolution. Galaxy Zoo, which uses volunteers from the general public to classify galaxies, and the Space Telescope A901/902 Galaxy Evolution Survey (STAGES) projects have used their vast datasets to disentangle the roles of “nature” and “nurture” in changing [...]
Artemisinin combination therapies (ACTs) could be almost as effective in reducing transmission of malaria as insecticide-treated bednets (ITNs) in areas of low transmission, a study based on data from Tanzania has found. In high transmission areas, long-acting antimalarial regimens may be needed to achieve significant transmission reductions.
Researchers identify neural pathways for novelty-seeking behavior
Astronomers discover two potential–and nearby–cosmic-ray sources
Something vital is missing in the far distant reaches of the universe: hydrogen — the raw material for stars, planets and possible life. The discovery of its apparent absence from distant galaxies by a team of Australian astronomers is puzzling because hydrogen gas is the most common constituent of normal matter in the universe.

From a quantitative standpoint, mineral oil is probably the largest contaminant of our body. That this contaminant can be tolerated without health concerns in humans has not been proven convincingly. An editorial in the European Journal of Lipid Science and Technology reflects on this and concludes that this proof either has to be provided or [...]

The steps needed to achieve speedy optical control of electron spin in a quantum dot are revealed in a new study published in the journal Nature. The instructions bring the prospect of fast quantum computers one step closer.
