[:es]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.

[:es]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.

[:es]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.

[:es]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.

[:es]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.
