For ants, unity is strength — and health
When a pathogen enters their colony, ants change their behavior to avoid the outbreak of disease. In this way, they protect the queen, brood and young workers from becoming ill. These results, from a study carried out in collaboration between the groups of Sylvia Cremer at the Institute of Science and Technology Austria (IST Austria) and of Laurent Keller at the University of Lausanne, are publish

Early human ancestors not to blame for extinctions of giant African mammals
Researchers analyzed a 7-million-year record of extinctions in Africa and compared it to milestones in human evolution previously implicated in these extinctions. Early hominin species played little to no role in driving mammal extinctions in ancient African ecosystems.

The origins of asymmetry: A protein that makes you do the twist
Asymmetry plays a major role in biology at every scale: think of DNA spirals, the fact that the human heart is positioned on the left, our preference to use our left or right hand. An international team led by a CNRS researcher has shown how a single protein induces a spiral motion in another molecule. Through a domino effect, this causes cells, organs, and indeed the entire body to twist, trigger

Intensification for redesigned and sustainable agricultural systems
Redesign of agricultural systems is essential to deliver optimum outcomes as ecological and economic conditions change. The combination of agricultural processes in which production is maintained or increased, while environmental outcomes are enhanced, is currently known as sustainable intensification (SI). SI aims to avoid the cultivation of more land, and thus avoid the loss of unfarmed habitat

Somatic mutant clones colonize the human esophagus with age
The extent to which cells in normal tissues accumulate mutations throughout life is poorly understood. Some mutant cells expand into clones that can be detected by genome sequencing. We mapped mutant clones in normal esophageal epithelium from nine donors (age range, 20 to 75 years). Somatic mutations accumulated with age and were caused mainly by intrinsic mutational processes.

Gate-induced superconductivity in a monolayer topological insulator
The layered semimetal tungsten ditelluride (WTe 2 ) has recently been found to be a two-dimensional topological insulator (2D TI) when thinned down to a single monolayer, with conducting helical edge channels.

Plio-Pleistocene decline of African megaherbivores: No evidence for ancient hominin impacts

Molecular to organismal chirality is induced by the conserved myosin 1D

ESCRT-dependent membrane repair negatively regulates pyroptosis downstream of GSDMD activation
Pyroptosis is a lytic form of cell death that is induced by inflammatory caspases upon activation of the canonical or noncanonical inflammasome pathways. These caspases cleave gasdermin D (GSDMD) to generate an N-terminal GSDMD fragment, which executes pyroptosis by forming membrane pores. We found that calcium influx through GSDMD pores serves as a signal for cells to initiate membrane repair by

Lake Erie algal blooms 'seeded' internally by overwintering cells in lake-bottom sediments

Now, evidence suggests humans and other vertebrates gained their unique attributes not from sheer number of genes, but from how they regulate the gen
