July 19, 2022 —The Prussian carp is considered one of the most successful invasive fish species in Europe. Its ability to reproduce asexually gives it a major advantage over competing fish. An international ...
Dec. 1, 2020 —A protein called CatSper1 may act as a molecular 'barcode' that helps determine which sperm cells will make it to an egg and which are eliminated along the ...
Mar. 16, 2021 —A new study has made a significant advance in the field of epigenetics by identifying how environmental information is transmitted by non-DNA molecules in the sperm. It is a discovery that advances ...
Dec. 21, 2022 —Damage to the paternal genome of the nematode Caenorhabditis elegans cannot be repaired and is instead passed on to its offspring, while the female egg repairs or limits the ...

Feb. 7, 2022 —Sexual reproduction allows organisms to mix up their genes and develop new adaptations to survive a harsh and ever-changing environment. Under nutrient-rich conditions, the worm C. elegans is ...
May 17, 2021 —Sperm are generally viewed as having just one action in reproduction -- to fertilize the female's egg - but studies are overturning that ...
July 4, 2023 —A detailed analysis of the dietary habits of elephants showed surprising variation from meal to meal, which could have important ramifications for wildlife protection and conservation ...
June 28, 2023 —Urea reacts extremely quickly under the conditions that existed when our planet was newly formed. This new insight furthers our understanding of how life on Earth might have ...
June 19, 2023 —Researchers have demonstrated how carbon dioxide can be captured from industrial processes -- or even directly from the air -- and transformed into clean, sustainable fuels using just the energy from the ...
June 16, 2023 —A 3D model of a 407-million-year-old plant fossil has overturned thinking on the evolution of leaves. The research has also led to fresh insights about spectacular patterns found in ...

July 11, 2023 —Humans began altering environments long before records were kept of the things that lived in them, making it difficult for scientists to determine ...
July 11, 2023 —Scientists find that the 'feel good' brain chemical dopamine regulates anxious worm behavior in the presence of nipping predators. The findings illuminate how this dopamine-regulated brain pathway ...
July 11, 2023 —A team has identified a protein that modifies the cellular machinery responsible for producing cellulose, which could inform the design of more stable, cellulose-enriched materials for biofuels and ...
July 10, 2023 —Movement in the Earth's tectonic plates indirectly triggers bursts of biodiversity in 36 million-year cycles by forcing sea levels to rise and fall, ...
July 7, 2023 —Plants regenerate using pluripotent callus tissues and initiating the de novo formation of shoot apical meristem (SAM). However, the mechanisms governing the efficiency of regeneration are unclear. ...
