Chew on this: Millions of years before the emergence of true mammals, an early ancestor had a tiny, saddle-shaped bone connected to the jaw that was thought to belong to mammals alone. That bone, ...

Dec. 8 (UPI) --To build a more structurally stable sodium-ion battery, a team of researchers from South Korea and the United States have turned to mammal bones and their multilayer geometry for ...

The lithium battery has long been the king of electronics. It powers everything from smartphones to self-driving cars — but it also has a serious problem with overheating and, at times, exploding.

Sodium-ion batteries offer several advantages over lithium-ion batteries; however, it is difficult to develop sodium cathodes, materials through which electrons can enter a battery. Many candidate ...

We humans tend to take our ability to chew and swallow for granted, but as mammals we actually have a pretty complicated system of bones and muscles helping us tackle our pizza slices and steaks.

Between backward-facing-feet, nipple-less milk secretion and egg-laying, platypuses and echidnas are some of the strangest mammals on Earth. While the amphibious platypus spends much of its time in ...

The arrangement of the bones that form the joint (the articulation) between the lower jaw and the skull is a key hallmark of vertebrates. Their configuration has long been used to draw a line in the ...

The lower jaws of lizards, birds, fish and even dinosaurs are comprised of multiple bones per side. Yet mammals diverged from all other vertebrates and settled on just one bone, repurposing the extra ...

New research suggests that land-based echidnas descended from semi-aquatic mammals. Gunjan Pandey CC BY-SA 4.0 via Wikimedia Commons Between backward-facing-feet, nipple-less milk secretion and ...
