As early as 7,400 years ago, Siberian dogs had evolved to be far smaller than wolves, making them more dependent on humans for food including sea mammals and fish trapped below the ice, a new study showed Friday......»»
How bacteria actively use passive physics to make biofilms
When we think about bacteria, we may imagine single cells swimming in solution. However, similarly to humans, bacterial cells often socialize, using surfaces to coalesce into complex heterogeneous communities called biofilms. Within a group, bacteria.....»»

Ancient DNA from Rapa Nui (Easter Island) refutes best-selling population collapse theory
Rapa Nui or Te Pito o Te Henua (the navel of the world), also known as Easter Island, is one of the most isolated inhabited places in the world. Located in the Pacific, it lies over 1,900 km east of the closest inhabited Polynesian island and 3,700 k.....»»
Archaeologists discover an ancient Neanderthal lineage that remained isolated for over 50,000 years
A fossilized Neanderthal discovered in a cave system in the Rhône Valley, France, represents an ancient and previously undescribed lineage that diverged from other currently known Neanderthals around 100,000 years ago and remained genetically isolat.....»»
Carbohydrate polymers could be a sweet solution for water purification
Water polluted with heavy metals can pose a threat when consumed by humans and aquatic life. Sugar-derived polymers from plants remove these metals but often require other substances to adjust their stability or solubility in water......»»

Researchers at the University of Jyväskylä, Finland, are developing a promising method to support the diagnosis of inflammatory bowel diseases (IBD) in horses. Awareness of the prevalence of IBD in both humans and animals has increased in recent de.....»»
A roadmap for using viruses to enhance crop performance
Humans, livestock and companion animals benefit from virus-based vaccines and gene therapies, but crops do not. This paradox is highlighted by an international research group led by the Institute of Molecular and Cellular Biology of Plants (IBMCP) wi.....»»
First robot leg with "artificial muscles" jumps nimbly: Study
Researchers said on Monday they had designed the first robotic leg with "artificial muscles"—oil-filled bags allowing machines to move more like humans—that can jump nimbly across a range of surfaces......»»
How much do vegan diets improve the health of dogs?
Pet food consumes at least 9% of all livestock globally, rising to 20% in nations such as the U.S. with high pet ownership. The environmental benefits of vegan pet diets were recently found to be game-changingly large. Most of these relate to dog foo.....»»
