Exact instanton transseries for quantum mechanics

The Borel plane of Bϕ. Credit: SciPost Physics (2024). DOI: 10.21468/SciPostPhys.16.4.103 In the quantum world, processes can be separated into two distinct classes. One class, that of the so-called “perturbative” phenomena, is relatively easy to detect, both in an experiment and in a mathematical computation. Examples are plentiful: the light that atoms emit, the energy … Read more

NASA hears from Voyager 1, the most distant spacecraft from Earth, after months of quiet

This illustration provided by NASA depicts Voyager 1. The most distant spacecraft from Earth stopped sending back understandable data in November 2023. Flight controllers traced the blank communication to a bad computer chip and rearranged the spacecraft’s coding to work around the trouble. In mid-April 2024, NASA’s Jet Propulsion Laboratory declared success after receiving good … Read more

US labor market can affect ‘people who are not even here’

US labor market can affect ‘people who are not even here’

Example migrant destination distributions for two municipios. These maps show the distributions of US destinations for migrants from two different municipios located in the state of Guanajuato: Dolores Hidalgo and Jaral del Progreso. Dolores Hidalgo tends to send migrants to US destinations that experienced relatively mild labor demand declines, while Jaral del Progreso tends to … Read more

The first glow-in-the-dark animals may have been ancient corals deep in the ocean

The first glow-in-the-dark animals may have been ancient corals deep in the ocean

This image provided by the Monterey Bay Aquarium Research Institute in April 2024 shows bioluminescence in the sea whip coral Funiculina sp. observed under red light in a laboratory. Most animals that light up are found in the depths of the ocean and they might have been doing it longer than thought. In a study … Read more

Satellite built by N.B. students not responding a week after entering Earth’s orbit

Satellite built by N.B. students not responding a week after entering Earth’s orbit

Hundreds of post-secondary students in New Brunswick are patiently waiting for a call from Satellite Violet. The student-built project took more than five years to develop at campuses across the province and is not communicating as expected. The satellite was delivered by a rocket to the International Space Station in early March and sent into … Read more
