The biopolymer lignin—one of the most important carbon reservoirs in plants and soils—not only decays through fungi or bacteria but can also be chemically attacked by iron linked to reactive oxygen species, without the involvement ...
Medical Xpress / A gut's complex architecture, recreated on a microscope slide–sized chip
Gut instinct, gut feeling or gutting it out—what exactly is the human gut? It's the workhorse of the digestive system and home to a vast, dynamic community of microorganisms that influence human health. In fact, the human ...
Phys.org / How a simple game of 20 questions could help make AI fit for the future
Artificial intelligence programs used to classify images could be trained much more cheaply using a surprisingly simple method inspired by the childhood game of 20 Questions, according to new research posted to the arXiv ...
Phys.org / Nearly 50 'ghost galaxies' emerge around three hosts, challenging dwarf galaxy counts
Dwarf galaxies—with a mass equal to about a billion suns, but often considerably less—are the most abundant in the universe. However, because of their low luminosity, they are very difficult to detect. They have mostly been ...
Medical Xpress / Making invisible cancers visible: A new route to turn 'cold' tumors 'hot'
One of the biggest challenges in cancer immunotherapy may not be that immune cells are too weak, but that some tumors give them too little to see. New research from Dana-Farber Cancer Institute scientists reveals how cancers ...
