Interview with Jennifer Mather, whose work involves cephalopod behaviour and human–animal interactions at the University of Lethbridge.

Lescroart, Nogales-Ascarrunz, et al. demonstrate that the contentious tiger cat species complex consists of five cryptic species. Based on analyses of 38 whole genomes from the Neotropical cat genus L...

A small, spotted tiger cat from Bolivia may just be the beginning of a wave of new small cat species.

A type of tiger cat, the animal is smaller than a house cat, slender and spotted. It lives in the Bolivian cloud forest.

Interview with Susana Coelho, who uses brown algae to study evolution, development, and life-cycle complexity at the Max Planck Institute for Biology.

Researchers used DNA and isotope analysis to figure out how the large cats survived in the far north.

In this review, Brusatte et al. discuss the wealth of new fossil discoveries and phylogenetic and macroevolutionary studies that have transformed our understanding of the origin, early diversification...

Dhanerawala et al. show that hippocampal reward cells are functionally segregated from the place cell spatial map. Temporally precise VIP+ interneuron activity bidirectionally controls reward cell num...

Snake embryos coil, but how and why they corkscrew remains unexplored. Weber et al. find that the embryos wind up clockwise via buckling of the rapidly elongating axial body against the slow-growing, ...

McCallum et al. uncover unexpected reproductive behaviors in wild male fish, including heightened aggression and competition, and declines in egg numbers and secondary sexual characteristics during wh...

Dapporto et al. show that butterfly beauty is associated with public attention, research, and EU conservation policy. Beauty bias spans the conservation landscape, yet European IUCN Red Lists identify...

Cytokinesis finalizes cell division by physically separating the daughter cells. After furrow ingression, the intercellular bridge (ICB) connecting th…

Ichizawa et al. show that cats maintain durable chemical individuality in urine through donor-specific branched-chain fatty acid (BFA) profiles stabilized by renal cortical lipid droplets. This kidney...

Interview with Lara Cassidy, who uses ancient genomes to study gene flow, population size and social processes in ancient societies at Trinity College Dublin.

The hyphae-to-yeast morphological transition promotes dissemination of the pathogen Candida albicans, but the mechanisms underlying this process are poorly defined. By identifying a bacterial metaboli...

The methane-generating enzyme from methanogenic archaea must be reactivated via a dedicated system. New molecular insights demonstrate that a key component of the reactivation machinery is redox sensi...

Neanderthals had a robust build, but the genetic basis remains unclear. Kanis et al. show that a Neanderthal growth hormone receptor variant increases cellular growth signaling and is inherited by som...

Suraci et al. show that large carnivores can make roadways safer by affecting prey space use and diel activity. Deer-vehicle collisions are reduced by up to 76% and shifted to daylight hours where pum...

Mochizuki reports a plant that lures pollinating flies by imitating the scent of ants injured by predators. This study reveals the first known case of ant mimicry in flowers and uncovers previously un...

Interview with Amandine Cornille, who studies the ecology and (epi)genomics of trees to understand their domestication, adaptation, and resilience to climate change at New York University Abu Dhabi.

Moots et al. use ancient DNA to compare woolly mammoth sex ratios from anthropogenic bone accumulations and natural depositional contexts. The results show that accumulations are female-biased, which ...

Neanderthals had a robust build, but the genetic basis remains unclear. Kanis et al. show that a Neanderthal growth hormone receptor variant increases cellular growth signaling and is inherited by som...

Adrian Glover and colleagues review evidence for impacts of the three types of deep-sea mining — nodules, hydrothermal vents and seamounts — on marine life and assess the potential for biodiversity lo...

Charles Davis and colleagues propose ethnobiodiversity informatics as an expansion of biodiversity informatics to represent human systems as explicit data layers, thus modeling more realistically the ...

The number of insect species is still an open question, with a recent study arriving at more than triple the current consensus and new species being discovered, highlighting the incompleteness of our ...
