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.
Mammals Can Use Their Intestines to Breathe
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.
Whole-Genome Data Point to Four Species of Giraffe
The genome sequences of 51 giraffes from all over Africa contribute to the latest attempt in an ongoing pursuit to pin down a species number.
No Transgenerational Effects of Chernobyl Radiation Found
The genomes of the children of people exposed to fallout from the Chernobyl nuclear accident appear to carry no trace of the incident.
