Alternative yeast joins genome party.
Budding yeast Saccharomyces cerevisiae makes way for a new genome star.
First there was budding yeast (Saccharomyces cerevisiae). Partly responsible for scientists survival by fermenting their staples beer and bread, they polished off its DNA sequence back in 1997.
Now the minority fungus of lab culture - fission yeast (Schizosaccharomyces pombe) - is fighting back. This week S. pombe enters the experimental big leagues, with the announcement of its completed genome1.
Quality over quantity
S. pombes genome highlights the dissimilarity between the two yeasts. S. pombe has 4,824 genes - about 1,000 less than its cousin, and fewer even than some bacteria. This is evidence of quality over quantity, says Nurse, who led the sequencing effort.
Despite the yeasts differences, "its what they share thats important", says Nurse. He hopes that comparing the two genomes will reveal exactly which parts are essential for yeast life.
Nurses team has already compared the S. pombe genome to another five completed ones - those of budding yeast, the nematode worm Caenorhabditis elegans, the fruit fly (Drosophila), mustard weed (Arabidopsis thaliana) and humans - to find commonalities. All six organisms are eukaryotes - unlike bacteria, they package up their DNA and protein production into distinct compartments within the cell. The team identified a toolkit of some 60 genes that are essential for organizing and dividing eukaryotic cells.
Armed with the genome, S. pombe researchers hope to wade into its proteome, identifying all its proteins and how they interact. But once again, theyre playing catch-up - budding-yeast researchers are well on their way towards this goal.
Still, S. pombe scientists are used to struggling for recognition. And, despite a slow start and early rivalry, "no one would argue for only one yeast now", says Russell.
Scientists still harking after S. cervisiaes brewing power may be won over by S. pombes potential. First described by Swiss researcher Lindner in 1893, he isolated it from East African millet beer - and named it after the Swahili word for beer, pombe.

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...

Let’s say the armrest is broken in your vintage car. As things stand, you would need a lot of luck and persistence to find the right spare part. But in the world of Industrie 4.0 and production with batch sizes of one, you can simply scan the armrest and print it out. This is made possible by the first ever 3D scanner capable of working autonomously and in real time. The autonomous scanning system will be on display at the Hannover Messe Preview on February 6 and at the Hannover Messe proper from April 23 to 27, 2018 (Hall 6, Booth A30).
Part of the charm of vintage cars is that they stopped making them long ago, so it is special when you do see one out on the roads. If something breaks or...
