With their distinctive black and white feathers, melodious calls, and intricate social interactions, magpies exhibit a level of avian cleverness that captivates both bird enthusiasts and researchers.However, what factors contribute to the success of these intelligent...
Lead scientist Stephanie Fraley works with one of the possibly infected blood samples used in the studyDavid Baillot/UC San Diego Jacobs School of EngineeringA new technique that melts bacterial DNA in blood samples could diagnose life-threatening infections faster than before.Typically, to detect harmful bacteria in a person's bloodstream, a blood sample is cultured in...
Humans interbred with Neanderthals and spread DNA across the world. Credit: DepositphotosNeanderthal DNA offered evolutionary advantages during environmental adaptation, yet it also introduced drawbacks, with nicotine addiction being one of the adverse effects associated with certain genesGenetic experts assert that six key indicators can reveal the presence of Neanderthal DNA.Approximately two percent of our...
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...
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...
