Companion animals could be reservoirs for cross-species transmission of antimicrobial-resistant bacteria
The emergence and global spread of antimicrobial resistant bacteria among companion animals (e.g., dogs and cats) pose a risk of the animals being reservoirs for cross-species transmission because of their close contact with humans......»»
Isotope analysis reveals mammoth as key food source for ancient Americans
Scientists have uncovered the first direct evidence that ancient Americans relied primarily on mammoth and other large animals for food. Their research sheds new light on both the rapid expansion of humans throughout the Americas and the extinction o.....»»
Warming oceans are changing marine habitats. A new study explores the impact on thousands of species
Every year, human activities release billions of tons of greenhouse gases into the atmosphere. These gases trap heat from the Sun, making the Earth warmer than it would be without them. Over 90% of the extra heat from greenhouse gases gets absorbed b.....»»
