Gene Variant Points to Starvation’s Evolutionary Legacy
Ancient and modern genomes reveal that a variant of the human growth hormone receptor likely helped our ancestors survive when food was scarce.
Accurate Protein Production Promotes Longevity
Worms, flies, and yeast live longer if the fidelity of their protein-making machinery is improved, a study shows.
7,200-Year-Old Skeleton Offers Clues to Early Human Migration
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 “Climate Catastrophe”: Western US Salmon on the Brink
A recent sampling from two California streams found nearly all juvenile salmon were infected with deadly parasites, and conditions are expected to worsen.
Cross-Resistance: One Cancer Therapy Can Undermine the Next
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.
WHO Releases New Recommendations on Human Genome Editing
The guidance comes after two years of consulting with hundreds of stakeholders, including indigenous peoples, religious leaders, patient groups, and scientists.
AI Controls Laser-Guided Robot Worms
Automated control of light-responsive nematode worms marks the first foray into the development of multicellular, biorobotic organisms.
Chimp Groups Have Their Own Distinct “Handshakes”
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.
Many Bacteria and Archaea Promoters Work Forward and Backward
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.
