Ancient DNA: African-Origin Cattle

Credit: phys.orgCattle, 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 Way Mouse Embryos Determine Between The Left And Right Sides

A light micrograph of a section through the thorax of a mouse embryo, which shows left–right asymmetry. RIKEN researchers have discovered how cilia detect fluid flow, which eventually leads to this asymmetry. Credit: Dr. Keith Wheeler/Science Photo LibraryThe process through which small hairs in embryos perceive fluid movement has been identified by biologists from...

Belt and Suspenders: Alpine Lake Bacteria Deploy 2 Light-Harvesting Systems

Lake Gossenköllesee is located in the Tyrolean Alps. Credit: Christopher BellasThough human beings, along with other vertebrate and invertebrate organisms, do not photosynthesize, we're certainly the downstream beneficiaries of the life forms that do. Phototrophic organisms at the bottom of the food chain convert plentiful sunlight into the energy that ultimately powers all other...

Researchers Confine Mature Cells to Turn Them into Stem Cells

Stem cells are the blank slate on which all specialised cells in our bodies are built and they are the foundation for every organ and tissue in the body.Maturing and resisting it has long been a prominent point in traditional and modern literary works in human history. From the unfortunate Qin Shi Huang's exploration...
