Brain reduces responses to sounds we expect to hear
The dorsal cochlear nucleus (DCN) is a cerebellum-like structure in the mammalian auditory brainstem that combines auditory nerve input with diverse auditory and non-auditory signals conveyed by…

Endangered Galápagos plant makes comeback from near extinction
A 30-year conservation effort has helped the critically endangered Galápagos snapdragon (Galvezia leucantha subsp. leucantha) recover from just six individuals to a small, carefully tended wild…
Scientists resurrect ancient proteins, offering new antibiotic leads
University of Oregon biologists have resurrected prehistoric proteins up to 160 million years old that carry natural antimicrobial properties. The revived molecules could inspire the design of new…
Relocating turtle nests to protect eggs may backfire unexpectedly
Moving threatened sea turtle nests to cooler, safer parts of the beach can save entire clutches from rising tides and extreme heat, but new research suggests it may have hidden consequences for the…
How Goosegrass Conquered a Brand New Volcanic Island
Opportunities to directly observe how life colonizes newly formed land and how ecosystems subsequently develop are exceedingly rare. In a study published in the Journal of Plant Research, researchers…

What Is Mitochondrial Dysfunction and Cellular Adaptation — And Why Does It Matter?
What Is Mitochondrial Dysfunction and Cellular Adaptation — And Why Does It Matter? When your cells face stress—whether from toxins, oxygen deprivation, or injury—they don’t simply surrender. Instead, they activate an intricate emergency response system, negotiating with their own internal power plants to survive under adverse conditions. Yet sometimes this negotiation fails, and mitochondria begin … Read more
