For 15,000 years, humans and dogs have been changing each other
Dogs have evolved from hunter-gatherer companions into specialized forms over approximately 15,000 years through mutual shaping with humans. They developed distinct adaptations including Arctic sled dogs, rainforest hunters, high-altitude breeds with genetic traits for thin air survival, and wool-producing varieties.

Extended drought has turned Britain's grass yellow as water becomes scarce during an exceptionally dry summer. Ancient underground structures like walls and ditches remain visible as green outlines because they retain moisture that sustains grass above them, while available water is prioritized for homes and farms.
Layered nano-biohybrid uses sunlight, air and water to make hydrogen peroxide
A layered nano-biohybrid material combining inorganic and biological components produces hydrogen peroxide using sunlight, air, and water as inputs. The technology was developed by a research team at the U.S. Department of Energy's Argonne National Laboratory.
Mutation hotspots help 'friendly' viruses outmaneuver the bacteria in your gut
Researchers identified mutation hotspots in bacteriophages that allow these viruses to rapidly evolve and overcome antibiotic-resistant bacteria in the gut microbiome. These genetic regions enable phages to adapt quickly enough to maintain their role in controlling harmful bacterial populations.
