Asexual yam species employs mimicry to trick birds and spread farther

Evolutionarily speaking, the ultimate goal of a lifeform is to reproduce and stave off extinction. Many plants and animals have evolved unique tricks to do so. One of these tricks is mimicry, which might be used to trick other species into believing it is dangerous in order to avoid becoming a meal, or to increase the likelihood of reproduction.

Can one use serum Lactate Concentration to Correct for the Anion gap?

Journal of Intensive Care Medicine, Ahead of Print. Patients in the intensive care unit often develop anion gap metabolic acidosis most commonly from lactic acidosis. Clinicians routinely measure serum lactate levels, but it is not clear if one is able to use the measured serum lactate level to determine … Journal of Intensive Care Medicine, Ahead of Print.

Practice Variation in Arterial Catheter Placement: A Survey of Pediatric Critical Care Practitioners

Journal of Intensive Care Medicine, Volume 41, Issue 2, Page 156-164, February 2026. BackgroundThere is not a consensus in critical care medicine on when arterial catheters are indicated, nor is there evidence that ACs improve patient outcomes. There is wide variability in AC use across PICUs that is independent of illness severity…. Journal of Intensive Care Medicine, Volume 41, Issue 2, Page 156-164, February 2026.

SARS-CoV-2 peptide fragments selectively dysregulate specific immune cell populations via Gaussian curvature targeting

Proceedings of the National Academy of Sciences, Volume 123, Issue 2, January 2026. SignificancePrevious work has demonstrated that the proteome of SARS-CoV-2 can potentially be a rich source of AMP-like viral fragments, exemplars of which are associated with severe COVID-like inflammation in vitro and in vivo. Here, we demonstrate that …

The major ion chemistry of seawater was closely coupled to the long-term carbon cycle during the Cenozoic

Proceedings of the National Academy of Sciences, Volume 123, Issue 2, January 2026. SignificanceDetermining past changes in the composition of seawater is important as seawater chemistry can be thought of as an integrated record of geological processes that drive the carbon cycle. In addition, seawater major ion chemistry data are …

Static and dynamic rough energy landscapes can lead to identical diffusivity

Proceedings of the National Academy of Sciences, Volume 123, Issue 2, January 2026. SignificanceIn a paper published in PNAS in 1988, R. Zwanzig introduced a model of diffusion in a rough potential, in which energy roughness reduces the effective diffusivity. Recently, this model has been used in numerous biophysics studies to reconcile …

Cell numbers contribute to cell fate during Ciona cardiopharyngeal mesoderm specification

Proceedings of the National Academy of Sciences, Volume 123, Issue 2, January 2026. SignificanceThe control of cell numbers is essential to many developmental processes, but it has been relatively understudied. A clear example of this can be seen in heart development. Hearts develop from precursor cells called cardiopharyngeal mesoderm. …

Elucidating cooperative genetic events in DCIS progression in mutant p53–driven breast cancer

Proceedings of the National Academy of Sciences, Volume 123, Issue 2, January 2026. SignificanceDuctal carcinoma in situ (DCIS) is a mammary precursor lesion with no clinical strategy to stratify indolent lesions from those that will become invasive, and the natural history of DCIS progression is unknown. The standard of care includes …

Gender stereotypes across nations relate to the social position of women and men: Evidence from cross-cultural public opinion polls

Proceedings of the National Academy of Sciences, Volume 123, Issue 2, January 2026. SignificanceThis project addressed the content of gender stereotypes and its relation to the distribution of women and men into social roles in society. The data derived from worldwide public opinion poll data with samples from 1995 and 2023 that …

O-acyltransferase genes involved in the production of volatile sex pheromones in Caenorhabditis elegans

Proceedings of the National Academy of Sciences, Volume 123, Issue 2, January 2026. SignificanceAs a step toward identification of the volatile sex pheromones (VSPs) that attract males as well as to understand where and under what conditions they are produced, we sought to identify genes necessary for VSP production. We generated loss-of-…

The anticipation of imminent events is time-scale invariant

Proceedings of the National Academy of Sciences, Volume 123, Issue 2, January 2026. SignificanceFrom everyday conversation to sports, to traffic, to music, people constantly predict when events will happen so they can prepare their next actions. This study examines how the brain makes such timing predictions over short periods of a few …
