Scientists have uncovered how the interplay between cell shape and mechanical stress influences the orientation of stomata (microscopic pores on the leaf surface) during early plant development.
Supermassive black holes are the largest known black holes in the universe, sitting at the center of most large galaxies. They are sometimes described as cosmic monsters because they feed on surrounding gas and dust when they are active, as well as destroy anything that gets too close. But their reputation could be due for a rethink, as a new paper published on the arXiv preprint server suggests they may also be the birthplace of millions of planets.
Discovering new catalysts is one of the central challenges in developing clean-energy technologies such as green hydrogen production. Yet catalyst discovery has traditionally remained confined within individual material families, limiting researchers' ability to transfer knowledge across chemically distinct systems.
Legal reforms designed to curb the abusive use of "SLAPPs" are insufficient to stop the rich and powerful trying to block freedom of speech, a new study warns. Measures in the U.S., U.K. and the EU to stop strategic lawsuits against public participation do not address the deep-seated inadequacies in the law which have a chilling effect on journalists and whistleblowers, the research says.
