Ants share decision-making, lessen vulnerability to 'information overload'
Scientists at Arizona State University have discovered that ants utilize a strategy to handle "information overload." Temnothorax rugatulus ants, commonly found living in rock crevices in the Southwest, place ...
Discovering the ozone hole: Q&A with Pawan Bhartia
On Sept. 16, 1987, representatives from nations around the world drafted a landmark treaty known as the Montreal Protocol. This step marked the beginning of the international agreement to phase out substances ...
Physicists experimentally demonstrate one-way quantum steering
Learning from sand castles to build future chips
In the United States, data centers already consume two percent of the electricity available with consumption doubling every five years. In theory, at this rate, a supercomputer in the year 2050 will require ...
Electron magnetic moment calculated precisely
(Phys.org)—An electron, as well as other subatomic particles with an electric charge, is actually a little magnet—it spins like a top, giving it its own magnetic moment.
Towards computing with water droplets—superhydrophobic droplet logic
Researchers at Aalto University, Finland, have developed a new concept for computing, using water droplets as bits of digital information. This was enabled by the discovery that upon collision with each other on a highly ...
New record in quantum communications
(Phys.org)—Researchers from The Australian National University have taken a quantum leap towards developing the next-generation super-fast networks needed to drive future computing.
To cap or not to cap: Scientists find new RNA phenomenon that challenges dogma
Some RNA molecules spend time in a restful state akin to hibernation rather than automatically carrying out their established job of delivering protein-building instructions in cells, new research suggests.
Getting serious about global gaming
(Phys.org)—Researchers at the University of Alberta have teamed up with colleagues in one of the world's leading centres on electronic gaming to form a network that will help close the gap between academia ...
