Synthetic tissue can repair hearts, muscles, and vocal cords

Combining knowledge of chemistry, physics, biology, and engineering, scientists from McGill University developed a biomaterial tough enough to repair the heart, muscles, and vocal cords, representing a major advance in regenerative ...

Extinct swordfish-shaped marine reptile discovered

A team of international researchers from Canada, Colombia, and Germany has discovered a new marine reptile. The specimen, a stunningly preserved meter-long skull, is one of the last surviving ichthyosaurs—ancient animals ...

Dopamine plays key role in songbird mating

In humans, the dopamine system has been tied to rewards and pleasurable sensations. As well as to memory and learning. A recent study from McGill University, published in Current Biology, suggests that dopamine may also play ...

How to turn specific genes on and off

All the cells in an individual's body bear the same genetic code. It is the reading and writing of this code—the "turning on" and "turning off" of specific genes in specific cells—that gives the cells their identities. ...

How bacteria create a piggy bank for the lean times

Bacteria can store extra resources for the lean times. It's a bit like keeping a piggy bank or carrying a backup battery pack. One important reserve is known as cyanophycin granules, which were first noticed by an Italian ...

How mussels make a powerful underwater glue

Blue mussels (Mytilus edulis) spend their days being buffeted by crashing waves. They manage to stay tethered to the rocks or their fellow mussels thanks to a highly effective underwater glue they produce. Because achieving ...

Unbreakable glass inspired by seashells

Scientists from McGill University develop stronger and tougher glass, inspired by the inner layer of mollusk shells. Instead of shattering upon impact, the new material has the resiliency of plastic and could be used to improve ...
