Bipedal footprints made 3.66 million years ago provide the clearest available evidence to date of the occurrence of marked body size variation in Australopithecus afarensis..

Over 7,000 novel translated sequences have been identified from human cells, including several hundred in annotated noncoding RNA, pseudogenes and de novo assembled transcripts.

Membrane mechanics predict that the ion channel Piezo recruits the surrounding membrane to amplify its sensitivity to changes in membrane tension, with greatest sensitivity in the low-tension regime.

Evolutionary dynamics of polyploid plants of the genus Cochlearia during past periods of rapid climate change indicate increased rates of speciation and diversification in response to pronounced glacial cycles and cold periods in particular.

A combination of massively parallel reporter assays and mass spectrometry uncovers the regulation of previously unexplored promoters across the Escherichia coli genome.

Social hierarchies resulting from the European colonization of the Americas stratified the population structure, leading to ancestry-related assortative mating and sex bias patterns that can be inferred from the genomes of the populations across the continent.

Traces of crawling locomotion, including children younger than 3 years old, are documented for the first time in the global human ichnological record.

Cutting down on long-distance air travel is the best way to reduce the emission of greenhouse gases by the scientific community.

The size of the mRNA fragment protected by a ribosome depends on the ribosome's conformation, which enables studies of the distinct steps of decoding and translocation at single-codon resolution.

Thousands of small Open Reading Frames are translated, and form two distinct classes based on their translational efficiency and bioinformatic indicators.
