Phys.org / Heavy traffic can turn flower-rich verges into bumblebee traps, study finds
Flower-rich road verges may attract hungry bumblebees, but at the same time, they can be dangerous for the buzzing insects—if traffic is too heavy. The new research from Lund University in Sweden examined the role roadsides ...
Phys.org / Ribosome-based gene circuit lets cells read six signals and trigger responses
The molecular machinery that normally builds proteins inside cells has now taken on a new role as a "switch." A research team at POSTECH (Pohang University of Science and Technology) has developed a new 'RNA-based smart gene ...
Phys.org / Tiny Jurassic bird reveals a key step in bird evolution
The transition from a lumbering, heavy dinosaur body to the flight-adapted bird body plan is one of many fascinating episodes in evolutionary history. Working out how this massive transformation took place relies heavily ...
