From Røy et al., (2012).
The slow metabolism of deep sea aerobic microorganisms is an adaptation found in those environments. In a recent study, microbial communities –some of which are 86 million years old– living at this slow metabolic rate in deep water sediments are reported.

Recent studies provide evidence on that most of the disease-related human gene variants are among the most rare ones. This challenges the idea of predicting disease risk from genomic profiles.

From Cozens, et al., (2012).
A recent study reported that mutations in a DNA polymerase can turn it into a RNA polymerase that can synthesize fragments up to 1.7 kb, a feature not observed in other mutants, which only synthesize short fragments.

Regions with high biological diversity have been found to also harbor a high degree of linguistic diversity. The most biologically and linguistically diverse spots on Earth have each more than 250 different indigenous languages, with New Guinera Wilderness Area at the top, with 976 native languages, of which 972 are endemic.

From Warmuth, et al., (2012).

A recent study unifies evidence from Archeology and Genetics and supports a scenario of domestic horse spread in which they have their origin in the western Eurasian steppes.
