Electric Eel Shocks Transfer Genes to Nearby Animals

A study has found that the discharge from an electric eel can transfer environmental DNA to nearby animalsDepositphotosA recent investigation indicates that the electrical discharge from an electric eel is potent enough to facilitate the transfer of genetic material from the surroundings into the cells of neighboring animals.In laboratory conditions, electroporation refers to applying...

The Initial Chimeric Monkey has Surfaced, Displaying Dual Sets of DNA

Images show the green fluorescence signals in different body parts of the three-day-old chimeric monkeyCao et al/Cell/(CC By SA)In a scenario reminiscent of the initial scenes in a science fiction horror movie, scientists have injected stem cells from a seven-day-old monkey embryo into an unrelated four-to-five-day embryo of the same species. This combined embryo...

This innovation streamlines the research process, eliminating the need for numerous animal experiments. By applying this novel approach, the scientists have pinpointed genes linked to a severe, rare genetic disorder.Typically, investigating the genetic origins of...

New Research Links Mitochondrial Gene Expression to Hypertensive Disorders of Pregnancy

Credit: Physiological Genomics (2023). DOI: 10.1152/physiolgenomics.00005.2023High blood pressure (hypertension) during pregnancy poses severe risks to the pregnant and fetus. A recent study sheds light on potential contributing factors to these dangerous disorders, focusing on changes in mitochondrial gene expression. The research offers valuable insights into understanding and potentially addressing hypertensive disorders during pregnancy.Examining Hypertensive Disorders of...

Scientists Find the Key to Virgin Birth and Enable it in Female Flies

Credit: PixaobayScientists have made a groundbreaking discovery by identifying the genetic cause of virgin birth in an unexpected species, the fruit fly ''Drosophila melanogaster''. Once this ability is activated in a female fruit fly, it can be inherited by successive generations.In this process, females can reproduce either sexually with the presence of males...

The Ancient African Continent DNA Revelation! The Amazing Truth
