Even the oldest eukaryote fossils show dazzling diversity and complexity

The sun has just set on a quiet mudflat in Australia's Northern Territory; it'll set again in another 19 hours. A young moon looms large over the desolate landscape. No animals scurry in the waning light. No leaves rustle ...

Single-celled protists in the guts of animals thrive without mitochondria, study finds

Almost all eukaryotic organisms, from plants and animals to fungi, can't survive without mitochondria, which generate chemical energy using oxygen. However, a new study by Lukáš Novák and Vladimír Hampl of Charles University, ...

A possible way for early life on Earth to survive cosmic radiation

A team of biophysicists affiliated with several institutions in China has uncovered via experimentation the means by which early life might have been able to survive cosmic radiation. In their study, reported in the journal ...

Circadian stress response provides an insight into metabolic communication via the mitochondrial epigenome

Who needs science fiction when you have the mitochondria? Billions of years ago, early plant and animal cells were infected by protobacteria which sought refuge from the outside world. Over time, these bacteria formed a symbiosis ...

The way a sperm tail moves can be explained by mathematics worked out by Alan Turing

Alan Turing might be best know for his work helping to crack Germany's "Enigma" communications code during the second world war. But he also came up with a theory where patterns can form just through chemical compounds spreading ...

Yeast with more than 50% synthetic genome is created in the lab

Researchers have combined over seven synthetic chromosomes that were made in the lab into a single yeast cell, resulting in a strain with more than 50% synthetic DNA that survives and replicates similarly to wild yeast strains.
