Phys.org / Stars forge elements in new, uncharted ways: Experimental physicist discusses the 'i-process'

All around us are elements forged in stars, from the nickel and copper in coins to the gold and silver in jewelry. Scientists have a good understanding of how these elements form: In many cases, a nucleus heavier than iron ...

Phys.org / Single-celled organisms have more complex DNA epigenetic code than multicellular life, researchers discover

Multicellular organisms (animals, plants, humans) all have the ability to methylate the cytosine base in their DNA. This process, a type of epigenetic modification, plays an important role in conditions such as cancer and ...
