A missing ingredient in dark matter theories?

In 1933, Fritz Zwicky, observing the Coma galaxy cluster, noted that single galaxies were moving too fast for the cluster to remain bound, according to the measure of visible mass. Only a far more significant amount of invisible matter could explain the strong gravitational force... click to read more

Shining a light on first contact in tuberculosis

In the science fiction series Star Trek, first contact between species occurs on a galactic scale; a recurring theme whose consequences are richly developed and explored throughout the series. In infection biology, first contact of a susceptible host with an infectious agent, albeit on a... click to read more

Go with the flow: dams could have a far-reaching impact on fisheries in tropical rivers

We need energy to sustain modern life. In most tropical developing countries, such as Brazil, energy is produced mainly through hydropower. This usually requires building dams, which negatively impacts the environmental and socioeconomic situation in the area. Many such dams are planned in tropical rivers, such... click to read more

Extending the genomic record of human diversity

The genetic material of any two humans is 99.9% identical, but the small differences that do exist between our genomes provide a record of the complex evolutionary history we have undergone as a species. Over the past decade, scientists have sequenced a large number of... click to read more
