Scientists have identified a new species of parasite infecting an invasive freshwater fish on the subtropical island of Okinawa, Japan. The results are part of a project to find parasites that have arrived in Japan with their non-native hosts and understand the role of parasites in natural ecosystems. Tracking parasites can be one scientific method to monitor ecosystem health and attempt to conserve biodiversity.
To adapt mortar to new building materials and industrial methods, the content in walls and plaster changed during the 20th century. The change meant that knowledge of historical materials and methods for producing mortar were lost. New research reveals that historical binding agents and mortar can be produced and used in present-day plaster restorations.
Gut bacteria can produce a clot-enhancing compound when people eat a nutrient found in a variety of foods including meat, eggs and milk, according to new research.
Whether a wound -- such as a diabetic foot ulcer -- heals or progresses to a worse outcome, including infection or even amputation, may depend on the microbiome within that wound.
The human microbiome appears to play a significant role in health and disease, but the mechanisms of how it does so is not well understood. Researchers have used the nematode C. elegans to decipher how specific bacterial signals influence a host, whether the host is a worm or a human. It reveals for the first time how bacterial genes modify worm biology, with implications for future study of the human microbiome.
