Virus-like transposons cross the species barrier, study shows

Scientists have known for decades that genes can be transferred from one species to another, both in animals and plants. However, the mechanism of how such an unlikely event occurs remained unknown. Now, researchers from ...

Astronomers scrutinize scorching-hot exoplanet

An international team led by Stefan Pelletier, a Ph.D. student at Université de Montréal's Trottier Institute for Research on Exoplanets have made a detailed study of the extremely hot giant exoplanet WASP-76 b.

Shrinking endoscopes with meta-optical fibers

Ultra-compact, agile endoscopes with a large field of view (FoV), long depth of field (DoF), and short rigid tip length are essential for developing minimally invasive operations and new experimental surgeries. As these fields ...

Researchers show mobile elements monkeying around the genome

Baboons (Papio) are found across the continent of Africa, from the west to the east and all the way south. They have doglike noses, impressive teeth and thick fur that ranges widely in color between the six species, which ...

A not-so-selfish 'genetic parasite' helps to preserve fertility

Ribosomal DNA (rDNA) sequences are essential parts of many species' genomes. The highly repetitive nature of these DNA sequences makes them susceptible to shrinkage over time—and if they shrink too much, cells die. If rDNA ...
