Earth's earliest life forms developed ways to survive the harmful effects of arsenic to cope with dramatic changes in their ...

During Earth's ancient Snowball periods, when the entire planet was wrapped in ice, life may have endured in tiny meltwater ...

In eukaryotes, DNA in cells is wrapped tightly around proteins called histones, which, in turn, are packed together into a structure known as chromatin.

Plants, algae, fungi, and animals — including humans — are all eukaryotes: life forms with complex, nucleus-containing cells. A recent discovery of organic compounds in ancient rocks in ...

Eukaryotes have been hugely successful because we are big, mobile and hungry. “The niche of macroscopic life was available for the taking,” Ettema said. Eukaryotes emerged to find a vacant role and ...

Prokaryotes were the first form of life, scientists believe that eukaryotes evolved from prokaryotes around 2.7 billion years ago. 1. Current doctrines on the origins of eukaryotes state that two ...

In the model, populations of prokaryotes and eukaryotes were under pressure to develop into multicellular organisms of different sizes and accumulate a larger genome. The researchers programmed one ...

Ancient organisms that bobbed through Earth’s waterways at least 1.6 billion years ago may not seem to have much in common with humans, but we couldn’t have evolved without eukaryotes called ...

A team of researchers led by Feng Zhang at the Broad Institute of MIT and Harvard and the McGovern Institute for Brain Research at MIT has uncovered the first programmable RNA-guided system in ...

It’s based on a protein called Fanzor, and this new finding is the first programmable RNA-guided system discovered in eukaryotes. The new RNA-editing system is described in a study published ...
