Salmon evolve quickly as a response to intense harvesting of their prey

Climate change and human activities impact living creatures in complex ways. In response, organisms may acclimate to those challenges during their lifetime or adapt over several generations, through genetic changes. Organisms with characteristics matching best their new environment, such as size at reproduction, will spread... click to read more

A crystalline silicon string played with hours-long sustain

When you tension a guitar string, you change its resonant frequencies and tune the pitch of the notes you can play on it. Similarly, a nanoscale string will perform faster oscillations (in the radiofrequency, megahertz band) by increasing the tension. However, when the aspect ratio... click to read more
