| The surprising organization of avian brains Posted: 25 Sep 2020 08:33 AM PDT Some birds can perform amazing cognitive feats - even though their forebrains seem to just consist of lumps of grey cells, while mammalian forebrains harbour a highly complex neocortex. A study reveals for the first time amazing similarities between the neocortex of mammals and sensory brain areas of birds: both are arranged in horizontal layers and vertical columns. |
| Spin clean-up method brings practical quantum computers closer to reality Posted: 25 Sep 2020 08:33 AM PDT Researchers create a quantum algorithm that removes spin contaminants while making chemical calculations on quantum computers. This allows for predictions of electronic and molecular behavior with degrees of precision not achievable with classical computers and paves the way for practical quantum computers to become a reality. |
| Metal wires of carbon complete toolbox for carbon-based computers Posted: 24 Sep 2020 11:15 AM PDT Carbon-based computers have the potential to be a lot faster and much more energy efficient than silicon-based computers, but 2D graphene and carbon nanotubes have proved challenging to turn into the elements needed to construct transistor circuits. Graphene nanoribbons can overcome these limitations, but to date scientists have been made only semiconductors and insulators, not the metallic wires to connect them. UC Berkeley scientists have now achieved the goal of a metallic graphene nanoribbon. |
| Unusual climate conditions influenced WWI mortality and subsequent influenza pandemic Posted: 24 Sep 2020 10:53 AM PDT Scientists have spotted a once-in-a-century climate anomaly during World War I that likely increased mortality during the war and the influenza pandemic in the years that followed. |
