Mighty Mississippi shapes commerce and fate of nations
The Mississippi River, central to American economy and psyche, powers inland trade, energy, and fisheries across 10 states. Figures cite 500 million tons of cargo yearly, 275 million daily loss from a 2008 spill, and 20 tons per day with 30 barges on average. The river’s vast basin and legacy influence policy, law, and livelihoods from New Orleans to Lake Itasca.

Paralysed man regains movement after spinal cord implant
Summers, 25, paralyzed below the chest in 2006, had an electrical stimulator implanted on the spinal cord in 2009. Within days he stood unaided and over months moved toes and legs, though he still relies on therapy and a wheelchair when the device is off. The Lancet report notes this is not a cure but a potential path to improved function.

Earliest mammals sniffed way to smarts
Washington AP report outlines how early mammals gained brains starting with the smell center, then touch and movement areas. Researchers led by Timothy Rowe analyze Morganucodon and Hadrocodium brains via CT scans, arguing olfactory prowess drove mammalian evolution and later adaptation. The study, in Science, cites Scripps and Smithsonian experts noting dusk or night activity and the enduring role of smell in early mammals.
