An MDC research team led by Jan Philipp Junker and Daniela Panáková has found that zebrafish can regenerate heart tissue after injury. Connective tissue cells play an important role in the process by temporarily entering ...
Polymers, large molecules made up of repeating smaller molecules called monomers, are found in nearly everything we use in our day-to-day lives. Polymers can be natural or created synthetically. Natural polymers, also called ...
Using the latest scientific methods, Tom Higham and Katerina Douka from the University of Vienna want to solve a great mystery of human evolution: Why are we the only humans left? Higham and Douka were the first ones to find ...
Early development is like a carefully choreographed dance, with uniform swaths of cells arranging themselves into elaborate patterns—a first step toward the formation of functional organs. A flat layer of skin cells, for ...
In molecular biology, transcription is the process of copying a segment of DNA into RNA, whereas a transcription factor (or TF) is a protein that controls the rate of copying this segment. The segments of DNA transcribed ...
There are many genes, or at least markers of one sort or another within our DNA sequences, that have been associated with height. By some estimates the number could be thousands. However, finding those select genes that have ...
The homotrimeric spike glycoprotein (S) from SARS-CoV-2, particularly its S2 subunit, is a fusion protein extraordinaire. It can fuse viral particles to cells and also fuse cells to cells to create multifarious syncytia among ...
An international team, led by researchers from the Universities of Vienna and Tübingen, and the Max Planck Society, has identified five new human fossils from the key site of Denisova Cave in southern Siberia. The remains, ...
Northwestern investigators have identified a novel approach to control the hierarchical assembly of protein pathways with DNA, according to a study published the Proceedings of the National Academy of Sciences (PNAS).
Astronauts face many challenges to their health, due to the exceptional conditions of spaceflight. Among these are a variety of infectious microbes that can attack their suppressed immune systems.
