Ancient and modern genomes reveal that a variant of the human growth hormone receptor likely helped our ancestors survive when food was scarce.


Worms, flies, and yeast live longer if the fidelity of their protein-making machinery is improved, a study shows.

Analysis of DNA from remains found in an Indonesian cave provides new insight into human movements among the islands between East Asia and Australia.

A recent sampling from two California streams found nearly all juvenile salmon were infected with deadly parasites, and conditions are expected to worsen.


Targeted cancer therapy may jeopardize the effectiveness of subsequent immunotherapy by reducing dendritic cell numbers and activation, according to study of mice and patient samples.

The guidance comes after two years of consulting with hundreds of stakeholders, including indigenous peoples, religious leaders, patient groups, and scientists.


Automated control of light-responsive nematode worms marks the first foray into the development of multicellular, biorobotic organisms.


A 12-year study shows variation among primate groups in how the animals clasp hands during grooming, but consistency within them, even as group membership shifts over time.

New analyses find that divergent transcription, in which one promoter directs the expression of two adjacent genes oriented in opposite directions, is conserved across all domains of life.

Researchers show that both mice and pigs are capable of oxygenating their blood via the colon—a capacity that, if shared by humans, could be leveraged in the clinic to minimize the need for mechanical ventilation.
