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.
Seventeen “Extinct” European Plant Species Found Alive
Plant species officially reported to be lost are in fact persevering in the wild, in seed banks or botanical gardens, or as other species now recognized to be taxonomic synonyms.
Extreme Exercise Carries Metabolic Consequences
Healthy people put through high-intensity interval training, or HIIT, displayed insulin resistance and mitochondrial dysfunction after working out excessively.
Lightning Might Have Sparked Early Life on Earth
Electrical storms, rather than meteorites as scientists had previously thought, could have unlocked phosphorus necessary for the development of ancient life, according to a new study.
Bispecific Antibodies Treat Cancer in Mouse Models
A trio of papers shows that specialized antibodies can direct T cells to destroy cells that display portions of mutant cancer-related proteins, as well as T cells that have become cancerous themselves.
Dogs Pass Test for Awareness of Their Own Bodies
Pets asked by their owners to pick up an object attached to a mat they were sitting on understood they needed to move in order to complete the task, researchers report.
Are Climate-Driven Shifts in Bat Diversity to Blame for COVID-19?
A study proposes that habitat for bats—and their accompanying coronaviruses—has increased in southern Asia over the last century, but experts debate the reliability of the analysis.
