Are dogs really bred for function? New Chapman study challenges the assumptions about certain breeds

A new study by Nicholas Hebdon and Lindsay Waldrop found substantial overlap in skull shapes across dog breeds and functional categories, challenging the prevailing belief that certain breeds are inherently superior at specific tasks. The researchers discovered no clear evidence of morphological specialization for bite work or scent work.

A hearing aid for … your nose?

A new study by Cold Spring Harbor Laboratory researchers explains how the brain updates associations between smells and sounds based on context. The findings suggest that a feedback loop between the olfactory cortex and olfactory bulb enables fast adaptation, allowing animals to fine-tune their motor responses accordingly.

Borrowing nature’s blueprint: How scientists replicated bone marrow

Researchers at the University of Pennsylvania School of Engineering and Applied Science have developed a platform that emulates human marrow's native environment. The device, called a bone marrow-on-a-chip, generates functional human blood cells and models the immune system's response to infections, paving the way for advanced drug dev...

Antibiotics of the future are prone to bacterial resistance

Recent studies have found that new antibiotics are prone to rapid development of resistance, even before they are widely used. This raises concerns about the effectiveness of these treatments in the long run. To address this issue, researchers call for a shift in antibiotic development prioritizing novel modes of action and responsible...
