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...

DNA Found in Paw Prints Can Now Be Used to Identify Polar Bears

Credit: Pixaobay Given dire forecasts suggesting the potential extinction of polar bears by the century's close, it becomes imperative for scientists to establish a means of tracking their population to gauge the effectiveness of conservation endeavors in mitigating the impacts of rapidly disappearing habitats. However, working safely with polar bears (Ursus maritimus) is notoriously challenging due...

Ancient DNA: African-Origin Cattle

Credit: phys.org Cattle, now iconic in American lore, were absent from the continent until the Spanish introduced them from Europe via the Canary Islands. A recent study analyzed ancient DNA from Caribbean and Mexican Spanish settlements, revealing that cattle from Africa were imported early in colonization, more than a century before documentation. Although historical records...

The  Ancient African Continent DNA Revelation! The Amazing Truth

We all have heard of Africa as the "cradle of humankind" or the "fountain of humankind”, due to the earliest evidence of human ancestors found here. A new research show on how the African ancestor mixture and a couple of truths on how they lived and connected came to light. A group of 44 researchers...

A recent study led by researchers at Weill Cornell Medicine and the National Heart, Lung, and Blood Institute, a division of the National Institutes of Health, has found that DNA has the ability to imitate protein functions by adopting intricate and three-dimensional structures. A recent study, published in...

Using Origami DNA to Trap Big Viruses

Graphical abstract. Credit: Cell Reports Physical Science (2023). DOI: 10.1016/j.xcrp.2022.101237 A group of scientists from the Technical University of Munich and the College of Regensburg, both in Germany, has discovered that it is possible to develop origami DNA frameworks that can be used to trap large viruses. In their paper released in the journal Cell Reports Physical...

DNA Gathered From Slave Skeletons Buried in Unmarked 18th-Century Burial Grounds Reveals Their History

A new study carried out by international scientists suggested that a team of Ashkenazi Jews-- victims of...

Building Human Muscle Genes in the DNA of Baker’s Yeast

Daran-Lapujade’s lab took human DNA (in red) encoding core functions in muscle cells, and inserted it into the DNA (chromosomes in purple) of a yeast cell (in yellow). The humanized yeast can be used as a tool for medical studies, for example in drug screening and cancer research. Credit: Ella Maru Studio / Pascale...

This Biohacker Became the First Person to Edit His Own DNA

Credit: CI Photos/Shutterstock Josiah Zayner is the first individual known to have modified his personal DNA and he revealed the planet just how easy it is to do, live-streaming the process on his blog, "Science, Art, Beauty". Zayner claims this was the second time he has genetically changed himself. Utilizing CRISPR, a fairly new gene-editing method,...
