Hope for spinal injuries as pigs walk again after experimental gel treatment for severed s
In humans and other mammals, spinal cord injuries can be devastating, leading to permanent loss of movement, sensation and bladder control. When severed axons (the long fibers that carry messages between nerve cells) cannot regrow, a dense scar forms, preventing nerve signals fro
How YouTube shapes public understanding of avian influenza
A new study analyzing more than 11,000 YouTube videos and comments found that online narratives surrounding avian influenza evolved alongside major outbreak developments, including increasing reports of infections in mammals, sporadic human cases and economic consequences. While
Zebrafish brains reveal alternate route for senses to the forebrain shared with mammals
Line up the brains of a fish, bird and a mammal, and something unexpected comes up. You do not see three different answers to the problem of making sense of the world. You see one answer, tilted three different ways. "You can really see it's almost like a continuum," says Emre Ya
Remarkable fossils rewrite the story of how animals conquered the land
Palaeontologists have found new evidence that the early ancestors of amphibians, reptiles and mammals did not have a larval stage with external gills like modern frogs or salamanders

Were Clovis foragers in Late Pleistocene North America big-game hunters, or just big-game
There are currently 15 well-documented Late Pleistocene localities in North America in which Clovis points are found associated with proboscidean remains (of mammoth, mastodon and gomphothere). Archaeologists routinely assume these localities represent evidence that Clovis people
Tooth fossil analysis suggests 'brawn before bite' in early Asian mammals
An analysis of fossil teeth from mammals that lived in China following the most recent major mass extinction suggests size came before both shape and function as diets diversified.
Global boom in livestock farming since 2006 is piling pressure on nature, report finds
Wildlife at risk as demand for cropland and water grows to feed 50% rise in farmed animals, campaign alliance saysThe number of mammals and poultry farmed worldwide has increased by half in the last two decades, research shows, and the amount of cropland used for feeding livestoc
Mammals use the same underlying system—preserved through evolution—to process smells
Picture a mouse taking rapid, staccato sniffs of a crumb it's found while foraging for food. Now compare that with a human leaning in for a single, deep inhale to gauge whether a cantaloupe is ripe. New research from Northwestern University has found that, like humans, mice also
