Bioremediation: getting to know the soil cleaners
Nowadays, bioremediation is one of the most viable alternatives for the recovery of contaminated soils. It consists in using biological agents, e.g. plants, that absorb pollutants and incorporate them into their organism. In this work, researchers from the UAB and the...
Invading ants
An important component in the biology of invaders is their expansion rate and pattern, both in time and space. Data on the first invasive stages are extremely difficult to obtain, although an a posteriori analysis of the expansion process is sometimes feasible.
The use of RNA interference as therapeutic tool
The latest discoveries in the field of RNA interference have revolutionized our knowledge of molecular and cellular biology. They have allowed to advance in therapies to treat serious diseases, like HIV. But this article proves that, at the present time, much is left to...
