Unravelling the genetics of fungal fratricide

Unravelling the genetics of fungal fratricide

Press Releases   •   Oct 15, 2018 12:38 BST

Selfish genes are genes that are passed on to the next generation but confer no advantage on the individual as a whole, and may sometimes be harmful. Researchers at Uppsala University have, for the first time, sequenced (or charted) two selfish genes in the fungus Neurospora intermedia that cause fungal spores to kill their siblings.

New knowledge about retrovirus-host coevolution

Press Releases   •   Oct 08, 2018 20:00 BST

Retroviruses have colonised vertebrate hosts for millions of years by inserting their genes into host genomes, enabling their inheritance through generations as endogenous retroviruses (ERVs). Researchers from Uppsala University now provide new knowledge about the long-term associations of retroviruses and their hosts by studying ERV variation and segregation in wild and domestic rabbits.

Artificial enzymes convert solar energy into hydrogen gas

Press Releases   •   Oct 04, 2018 10:02 BST

In a new scientific article, researchers at Uppsala University describe how, using a completely new method, they have synthesised an artificial enzyme that functions in the metabolism of living cells. These enzymes can utilize the cell’s own energy, and thereby enable hydrogen gas to be produced from solar energy.

​World speed record for polymer simulations

​World speed record for polymer simulations

Press Releases   •   Oct 04, 2018 08:34 BST

Star polymers are within the most topologically entangled macromolecules. With a simulation over a hundred times faster than earlier studies, it is demonstrated that the mean square displacement scales with a power law 1/16 in time, instead of the previously assumed zero. It suggests that star polymer motion is the result of two linear relaxations coinciding in time.

Understanding how cells within tumors respond to drugs is a critical issue in anticancer drug development. In an article published in Cell Chemical Biology researchers from Uppsala University report a new approach to study cancer cells’ reactions to treatments and present how it can be used to find new promising drug combinations.
