The three-dimensional shape of a protein can be used to resolve deep, ancient evolutionary relationships in the tree of life, according to a study in Nature Communications. It is the first time researchers use data from protein shapes and combine it with data from genomic sequences to improve the reliability of evolutionary trees, a critical resource used by the scientific community for understanding the history of life, monitor the spread of pathogens or create new treatments for disease. Crucially, the approach works even with the predicted structures of proteins that have never been experimentally determined. The findings open the door to using the massive amount of structural data being generated by tools like AlphaFold 2 and help open new windows into the ancient history of life on Earth.
Urban infrastructure, such as stormwater management ponds (SWMPs), have the potential to be rehabilitated and provide critical freshwater habitat in urbanized watersheds if designed adequately. We tracked different native fish species using passive integrated transponder technology to assess the level of connectivity between a rehabilitated SWMP and a river. We found a high degree of connectivity between the two habitats, even during challenging environmental conditions such as high water temperatures and abundant submerged vegetation.
A new Australian study has revealed a potential reason why some pregnancies achieved through assisted reproductive technology (ART) may result in birth defects in comparison to naturally conceived pregnancies.
