A single amino acid change in the light-sensing rhodopsin protein played a critical role when herring adapted to the red-shifted light environment in the Baltic Sea, shows an study by an international team of scientists, led by researchers from Uppsala University, which is published in PNAS. Remarkably about one third of all fish living in brackish or freshwater carry the same change.

Bacterial ribosomes need a single-stranded ribosome binding site (RBS) to initiate protein synthesis, whereas stable RNA structure blocks initiation. Paradoxically, structured mRNAs can nevertheless be efficiently translated. Researchers at Uppsala University have now elucidated the anatomy of a "standby" site and its requirements, to overcome RNA structure problems for translation.

The majority of women who undergo surgery for suspected ovarian cancer do not have cancer. A novel blood test developed by researchers at Uppsala University and University of Gothenburg, now offers the possibility of more precise diagnostics. This could lead to a reduction in unnecessary surgery and to earlier detection and treatment for affected women. (Communications Biology).

New data from the Uppsala Conflict Data Program (UCDP), Uppsala University shows that in 2018 the number of fatalities in organised violence reached the lowest level in seven years. However, the large share of internationalised conflicts, to which external states contribute troops, worries researchers. These conflicts tend to be both bloodier and longer.
Infants later diagnosed with autism follow adults’ gaze, but seldom initiate joint attention themselves

Both infants and their parents flexibly several behaviors to establish frequent episodes of joint attention. A new study shows that infants who are later diagnosed with autism seldom actively seek to establish such episodes themselves. This finding provides support for the view that children with autism have reduced social motivation already as infants.

Should public health-care systems provide couples with expanded screening for genetic disorders before they decide to become pregnant? Screening programmes could increase our reproductive choices and autonomy. But there are ethical issues at stake.

Norse World is a new database which will make it easier for researchers to study perceptions of the surrounding world in Medieval Scandinavian literature. The new tool is a digital resource aimed at researchers in fields such as language history and philology, comparative literature, manuscript studies and digital humanities. It will be freely available to both researchers and the public.

Through random mutation the sequences of our proteins slowly change over time, usually without affecting function. But sometimes new functions will be invented in this process. Scientists at Uppsala University have studied such a case in molecular detail. The results are published in Science Advances and show how several factors conspire to shape a plastic protein-protein interaction.

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.

A new study by researchers at Uppsala University and INGV, Italy, sheds light on magma storage under the currently active Agung volcano on the island of Bali in Indonesia. Magma at Agung is stored at both mantle (~20 km) and shallow crustal (~5 km) depths, which may be a potential cause for sudden pressure-driven eruptions in this densely populated part of the world.
