Chemical in Widely Used Sweetener is "Genotoxic", Study Finds

A new study finds a chemical formed when we digest a widely used sweetener is "genotoxic," meaning it breaks up DNA.

Genomic Evidence: Atlantic Cod Evolved New Traits Rapidly During Overfishing Period

The overfishing of codfish spanning the second half of the 20th century indicates that human action can force evolutionary changes more quickly than widely believed, according to a Rutgers-led study.

Newly Identified Cellular Mechanism Enhances Photosynthesis in Marine Phytoplankton

Take a deep breath. Now take nine more. According to new research, the amount of oxygen in one of those 10 breaths was made possible thanks to a newly identified cellular mechanism that promotes photosynthesis in marine phytoplankton.

Exploring How Flying Insects Locate an Odor Source by Navigating Microscale Winds

How do flying insects like important pollinators locate odor sources in the great outdoors, despite encountering highly variable wind conditions? They use odor plumes -; which travel like smoke and form when the wind blows odor molecules from their source -; to track down sources such as flowers or pheromones.

X-Ray Imaging Enables the Classification of Previously-Unidentified Marine Reptile Fossil From Svalbard

X-ray examination has enabled the classification of a previously-unidentified marine reptile fossil from Edgeøya, Svalbard, and the technique could provide future unique insights into ancient life here, according to a study published May 31, 2023 in the open-access journal PLOS ONE by Victoria S. Engelschiøn of the University of Oslo and colleagues.

New Genome-Wide Testing Finds Greater Proportion of Pure Dingoes in the Wild Than Previously Thought

Wild dingo populations have less dog lineage, with a significantly greater proportion of pure dingoes than previously thought, according to new research, challenging the view that pure dingoes are on the decline due to crossbreeding.

Sucrose Acts as a Signal Transmitter for Light-Dependent Root Architecture Formation in Arabidopsis

Plant growth is driven by light and supplied with energy through photosynthesis by green leaves. It is the same for roots that grow in the dark – they receive the products of photosynthesis, in particular sucrose, i.e. sugar, via the central transportation pathways of phloem.
