Mayara da Silva Santos, doctoral candidate at the University of Freiburg's Institute of Physics, has discovered a new oxidation state of rhodium. This chemical element is one of the most catalytically important platinum-group metals and is used, for.....»»
Research team discovers how to convert 3D-printed polymer to stronger, ductile hybrid carbon microlattice material
Developing a lightweight material that is both strong and highly ductile has been regarded as a long-desired goal in the field of structural materials, but these properties are generally mutually exclusive. However, researchers at City University of.....»»
Contact between wild birds and backyard chickens is risky
Wild birds come into contact with backyard chicken flocks more frequently than people realize, creating a pathway for pathogens to transmit back and forth, according to new research from the University of Georgia. Such pathways increase the risk for.....»»
Treating antibiotic-resistant infections with peptides inspired by human saliva
Antibiotic resistance is a problem that impacts tens of millions of people each year worldwide. According to the CDC, "more than 2.8 million antibiotic-resistant infections occur in the United States each year, and more than 35,000 people die as a re.....»»
Scientists develop new technique to reveal the hidden genome
Using an innovative new technique, scientists at Duke-NUS Medical School and their collaborators have identified thousands of previously unknown DNA sequences in the human genome that code for microproteins and peptides potentially critical to human.....»»
How does the autophagic pathway regulate low-nitrogen tolerance in tomato?
Nitrogen (N) deficiency first affects the N uptake and assimilation systems of plants. Nitrate, the main source of plant N, is absorbed and transported by nitrate transporters. Nitrate can be metabolized directly in the roots after absorption and sto.....»»
