A new study from the MRC Laboratory of Medical Sciences (LMS) in London, UK reveals how ancient viral DNA once written off as “junk” plays a crucial role in the earliest moments of life. The research, published in Science Advances, begins to…

Targeting bacterial 'decision-making' could help outsmart antibiotic resistance
Antibiotic resistance is a growing global health crisis that makes common infections harder to treat and puts many medical procedures at risk. Now, Carnegie Mellon University researchers have uncovered a vulnerability in bacteria that could pave…

Expansion of invasive Chinese hwamei into alpine habitats in Japan: First record of songs
Researchers at University of Tsukuba have, for the first time, recorded the songs of the Chinese hwamei Garrulax canorus (designated as an invasive alien species) in the alpine zone of Mt. Kisokoma in the Central Alps (approximately 2,770 m above…

Pressing pause: A small genetic stop may have helped complex life evolve
Humans have it. So does Drosophila. But not yeast. That “it” is a small pause at the start of gene activity—a brief molecular halt that may have helped life evolve from simple cells to complex animals.

Phage-resistant bacteria can still sink carbon to ocean floor
Marine bacteria are key to determining whether carbon is recycled near the ocean surface or transported to deeper waters, but many operate in constant threat of being infected by viruses called phages, and mutate to fend off those infections.

Uncovering how parasitic plants avoid attacking themselves to improve crop protection
Parasitic plants are notorious agricultural pests that drain nutrients from crops and cause economic losses of more than USD 1 billion due to yield losses every year. Yet these plants almost never attack themselves or closely related plants….

Exploring the connection between gene expression and aging
Northwestern Medicine scientists have discovered how molecular “traffic controllers” in cells influence aging and cellular senescence—a state where cells stop dividing but remain metabolically active. The study, published in Molecular Cell,…
