Researchers have developed a method for determining the accuracy of quantum simulations. The new method not only reconstructs the dynamics of a quantum system from experimental data, but can also quantify the uncertainty of the predictions derived from it. The verification method was demonstrated in Innsbruck, Austria, on an ion-trap quantum computer with up to 51 qubits.
New research argues that interacting with robots displaying human-like behaviors can cause people to adopt robot-like traits or ‘robotoid humanness.’
Nature provides resources to society, and the diversity of species is expected to underpin human economies. So why then are the poorest countries also those that are are richest in wildlife and contain a high number of different species? According to new research, the reason is that colonial exploitation of that biodiversity by now-rich countries created poverty legacies that still persist today.
The research team, from Trinity College Dublin, University of Bern, Swiss Federal Institute for Aquatic Science and Technology, and the Wyss Academy for Nature, assessed datasets from 168 countries, which included World Bank poverty statistics, biodiversity records, governance indicators, colonial history, and protected-area coverage. The headline finding was that the regions most targeted by colonial powers were generally those richest in biodiversity, which has contributed to the modern structures of poverty.
To what extent does the allocation of aid for combating disease correspond to disease burden? LMU researchers have developed a machine learning pipeline that helps uncover relative discrepancies in aid distribution.
Self-assembling, anthracene-based supramolecular nanofibers can enable excitons to migrate hundreds of nanometers, according to a new experimental finding by researchers at Science Tokyo. Coupling these nanofibers with a plasmonic nanohole gold substrate further doubles exciton diffusivity. By mitigating the limited diffusivity of singlet excitons in organic semiconductors, this offers a new strategy for improving optoelectronic technologies.
Drawing inspiration from the dynamic architecture of living systems, researchers from Institute of Science Tokyo and Kyoto University have harnessed two chemically fueled biomolecular nanomachines, DNA polymerase and kinesin, to synthesize and actively assemble complex, hierarchical DNA networks. The work opens a route toward programmable, lifelike synthetic materials built from the nanoscale up.
