Researchers at University of Tsukuba and The University of Tokyo have discovered that radio waves emitted from primordial hydrogen gas in the early Universe contain a "fingerprint" that reveals the properties of dark matter. Theoretical calculations have accurately reproduced the distribution of dark matter and the state of hydrogen gas in the early Universe. Radio observatories planned for construction on the Moon are expected to detect these signals, advancing our understanding of the true nature of dark matter.

Researchers have uncovered how dissolved biochar—tiny carbon particles derived from burning plant material—affects soil nematodes, shedding light on both benefits and risks to these important ecosystem players. The study focused on the common laboratory worm, Caenorhabditis elegans, revealing that the impact of dissolved biochar strongly depends on the amount present in the environment.

MIT researchers found that subtle chemical patterns persist in conventionally manufactured metal alloys, despite the mixing involved. The surprising finding could be used to tune metallic properties for aerospace, energy, and more.

Water quality could impact the kind of microbial populations in poultry drinking water lines and lead to the buildup of a biofilm that can harbor pathogenic bacteria like Salmonella, according to a recently published study by researchers with the Arkansas Agricultural Experiment Station and the Mississippi Agricultural and Forestry Experiment Station.
