New AI approach accelerates targeted material discovery and creates foundation for self-driving experiments

by

Specification of an example experimental goal and translation into an automated data acquisition strategy. a Visualization of the design space and the corresponding measured property space for an example material system. Samples from the design space (a discrete set of design points) are directly mapped to a set of measured properties (measured property space). The … Read more

Scientists demonstrate chemical reservoir calculation using the formose reaction

by

A schematic overview of the formose reservoir computer. Credit: Nature (2024). DOI file: 10.1038/s41586-024-07567-x Researchers from the Institute for Molecules and Materials at Radboud University have shown that a complex self-organizing chemical reaction network can perform various computational tasks, such as nonlinear classification and complex dynamical predictions. The field of molecular computing interests researchers who … Read more

Scientists Weighed a Neutron Star to Discover the Strange Physics Inside

by

Neutron stars are among the most extreme objects in the universe. Formed from the collapsed cores of supergiant stars, they weigh more than our sun and yet are compressed into a sphere the size of a city. The dense cores of these exotic stars contain matter compressed into unique states that are impossible for us … Read more

‘A History of Contact’: Geneticists Rewrite the Story of Neanderthals and Other Early Humans

by

Detection of modern human-to-Neanderthal gene flow (H→N) and its consequences. Modern human-to-Neanderthal admixture causes a local increase in heterozygosity in the Neanderthal genome, a feature that enabled approaches to quantify and detect introgressed sequences. We used modern human-introgressed sequences in the Neanderthal genome to refine estimates of Neanderthal ancestry in contemporary humans by decomposing IBDmix-detected … Read more

Physicists suggest that tachyons can be reconciled with special relativity

by

Source: Pixabay/CC0 Public Domain Tachyons are hypothetical particles that travel at speeds greater than the speed of light. These superluminal particles are the “enfant terrible” of modern physics. Until recently, they were generally considered as entities that did not fit into special relativity. However, an article recently published in Physical assessment D by physicists from … Read more

Theoretical physicists discover that the Higgs boson does not appear to contain harbingers of new physics

by

The Higgs boson (blue) can be created by the interaction of gluons (yellow) during proton collisions. Protons consist of two up quarks (red) and one down quark (purple), so strongly bound by gluons that in the sea of ​​virtual particles (gray) heavier quarks and antiquarks, for example beautiful quarks, can appear, whose presence also influences … Read more

Time could be a mirage created by quantum physics, a study suggests

by
An artist

New research suggests that time may not be a fundamental element of the universe, but rather an illusion created by quantum entanglement. Time is a difficult problem for physicists; the inconsistent behavior of our best theories of the universe contributes to a stalemate that leaves researchers unable to find a “theory of everything,” or a … Read more

Astronomers discover dozens of double-aligned white dwarf binaries

by

The detection efficiency for a double-line DWD where the two stars have similar flux contributions. Credit: arXiv (2024). DOI number: 10.48550/arxiv.2407.02594 An international team of astronomers reports the discovery of 34 rare double-lined white dwarf binary systems using the Intermediate-dispersion Spectrograph and Imaging System (ISIS) on the William Herschel Telescope (WHT). The finding was detailed … Read more

New method achieves tenfold increase in quantum coherence time via destructive interference of correlated noise

by

A Bloch sphere of a qubit subjected to cross-correlated noise (blue and red). The method destructively disrupts this noise, resulting in superior performance. Credit: Physical assessment letters (2024). DOI: 10.1103/PhysRevLett.132.223601 Researchers have developed a new method to significantly improve the performance of quantum technology by using the cross-correlation of two noise sources to extend coherence … Read more
