Unexpected differences between rats and mice gives new insight into the male parental brain

By making use of an unexpected species difference between rats and mice, scientists have identified a system in the brain that controls how males behave when they become fathers. A central component in this system is the hormone, prolactin, which has previously been shown to prepare the female for motherhood. The researchers were also able to control how much interest the males took in their offspring by experimental manipulations. These findings were published in the scientific journal Cell.

There are large amounts of branches and tops on the felling sites, which could be used for many useful things, including for clothing textile fabrics. Photo: Mostphotos/Kennerth Kullman.

Roots and branches will become clothes for healthcare professionals

Residues from Swedish forestry will replace cotton in the production of clothing textile fabrics for attire worn by healthcare providers, and thus reduce the climate load. This is the goal with a research project underway at Stockholm University in collaboration with Region Stockholm.

Återvinningen av laddningsbara hydridbatterier kan bli enklare med en ny metod, enligt en ny studie. Laddningsbara batterier finns av olika sorter, stora som små, och metoden är användbar för alla typer av NiMH-batterier. Foto: Paninastock/Mostphotos

In silico studies towards highly specific antibodies for the novel coronavirus

A Brazilian research group together with professor Aatto Laksonen from the Department of Materials and Environmental Chemistry at Stockholm University and Petru Poni Institute in Iasi have confirmed how the spike protein receptor binding domain of the new coronavirus enters the human cell. Based on these molecular insights the researchers have been able to propose more efficient binder candidates. This discovery has the potential to improve the development of a new vaccine and/or an antiviral drug. These recent findings are published in the scientific journal Virus Research.

New crystalline calcium phosphate may lead to innovative biomedical applications

Researchers at the Department of Materials and Environmental Chemistry have discoverad a novel crystalline member of the calcium orthophosphate mineral family. This is an important class of biominerals for humans as it is an essential constituent of bone and tooth enamel. The discovery may result in new biomedical applications and improve the understanding of the biomineralization processes. The discovery was published in Nature Communications.

Scientists discover how malaria parasites import sugar

Researchers at the Department of Biochemistry and Biophysics has established how sugar is taken up by the malaria parasite, a discovery with the potential to improve the development of antimalarial drugs. The research is published in the scientific journal Nature.

The molecular structure of the photosynthetic complex I protein, which is located in the thylakoid membranes of cyanobacteria. The protein consists of various coupled modules, which capture electrons from the other photosynthetic proteins, pump protons across a biological membrane, and concentrate carbon dioxide.

Protein machine by which cyanobacteria concentrate carbon dioxide from the atmosphere revealed

For the first time, researchers from Stockholm University together with collaborators from Germany and Japan have solved the atomic structure of the photosynthetic complex I – the protein responsible for the carbon concentration process in the atmosphere. It is a step towards understanding how photosynthesis, the driving force behind all aerobic life on Earth, works at cellular level. The study was published in the journal Nature Communications.
