The unintended consequences of dams and reservoirs

The unintended consequences of dams and reservoirs

Press Releases   •   Nov 13, 2018 16:54 GMT

An international team of drought scientists show that while many dams and reservoirs are built, or expanded, to alleviate droughts and water shortages, they can paradoxically contribute to make them worse. The study is published in Nature Sustainability.

Researchers capture in-action images of photosynthetic protein complex splitting water

Researchers capture in-action images of photosynthetic protein complex splitting water

Press Releases   •   Nov 07, 2018 18:00 GMT

In a new article published in Nature an international research team presents high-resolution images of photosystem II, the protein complex that splits water into hydrogen ions and oxygen during photosynthesis. The images will help researchers better understand this complex mechanism, possibly opening up the door to developing cheap and efficient solar fuel devices.

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.
