Chemists discover structure of glucagon fibrils

Patients with type 1 diabetes have to regularly inject themselves with insulin, a hormone that helps their cells absorb glucose from the bloodstream. Another hormone called glucagon, which has the opposite effect, is given ...

New genes out of nothing

One key question in evolutionary biology is how novel genes arise and develop. Swedish researchers now show how new genes and functions that are advantageous to bacteria can be selected from random DNA sequences. The results ...

What artificial intelligence can teach us about proteins

Proteins are vital parts of all living organisms and perform essential tasks in our bodies. They build and repair tissues, supply components of the immune and hormone systems, regulate metabolism, and transmit signals. Researchers ...

Surface protein editing in bacteria

University of Minnesota researchers have discovered this previously unknown signaling pathway that regulates surface proteins on bacteria that can lead to new targets for antibiotics.

Researchers combining animate and inanimate substances

Modern cosmetics and medical implants contain many inorganic substances. Studies by South Ural State University researchers are aimed at understanding how biological molecules of the human body will interact with new, foreign, ...

Cell editors correct genetic errors

Almost all land plants employ an army of cellular editors who correct errors in their genetic information. Researchers at the University of Bonn have now transferred parts of this machinery into a bacterium. Their results ...

Structural insights into tiny bacterial harpoons

New research sheds light onto how different bacterial species can build complex nano-harpoons with different protein building blocks. Bacteria use these harpoons called Type VI secretion systems to inject toxins into nearby ...
