Quantum Convolutional Neural Networks |
Wednesday, September 11, 2019 - 14:20 |
 |
Fig. 1: The concept of QCNNs (Cong, et al.*) Machine learning techniques have so far proved to be very promising for the analysis of data in several fields, with many potential applications. However, researchers have found that applying these methods to quantum physics problems is far more challenging due to the exponential complexity of many-body systems. |

Shape-Shifting Sheets |
Thursday, August 22, 2019 - 10:23 |

Researchers have developed a mathematical framework that can turn any sheet of material into any prescribed shape, inspired by the paper craft kirigami (from the Japanese, kiri, meaning to cut and kami, meaning paper). Unlike its better-known cousin origami, which uses folds to shape paper, kirigami relies on a pattern of cuts in a flat paper sheet to change its flexibility and allow it to morph into 3D shapes... |

DNA "Propellers" to Study How DNA and Proteins Interact |
Wednesday, July 31, 2019 - 10:09 |
 |
For decades, researchers have chased ways to study how biological machines power living things. Every mechanical movement — from contracting a muscle to replicating DNA — relies on energy-fueled molecular motors that take tiny, near-undetectable steps. Trying to see these movements is like trying to watch a soccer game on the moon from Earth. |

Phase transitions occur when a substance changes from a solid, liquid or gaseous state to a different state—like ice melting or vapor condensing. During these phase transitions, there is a point at which the system can display properties of both states of matter simultaneously. A similar effect occurs when normal metals transition into superconductors... |

The problem with string theory, according to some physicists, is that it makes too many universes. It predicts not one but some 10500 versions of spacetime, each with their own laws of physics. But with so many universes on the table, how can the theory explain why ours has the features it does?.. |
