Radio-loud active galactic nucleus detected in the protocluster SPT2349-56 - Phys.org

health

Using the Australia Telescope Compact Array (ATCA), an international team of astronomers has observed the population of submillimeter galaxies in a protocluster known as SPT 2349-56. As a result, they found a radio-loud active galactic nucleus in the protocluster's central region. The discovery was detailed in a paper published January 3 on the arXiv preprint server.

New research has been published on the organic analysis of the Winchcombe meteorite that crash landed onto a driveway in Winchcombe, Gloucestershire in 2021. The research, led by Dr. Queenie Chan, from the Department of Earth Sciences at Royal Holloway, University of London, found organic compounds from space that hold the secrets to the origin of life.

Electrons take new shape inside unconventional metal - Phys.org

science

One of the biggest achievements of quantum physics was recasting our vision of the atom. Out was the early 1900s model of a solar system in miniature, in which electrons looped around a solid nucleus. Instead, quantum physics showed that electrons live a far more interesting life, meandering around the nucleus in clouds that look like tiny balloons. These balloons are known as atomic orbitals, and they come in all sorts of different shapes—perfectly round, two-lobed, clover-leaf-shaped. The number of lobes in the balloon signifies how much the electron spins about the nucleus.

Study: Deal Lake caught in seasonal cycle of harmful algal blooms - Phys.org

Credit: Unsplash/CC0 Public Domain April showers bring July harmful algal blooms (HAB) in New Jersey's largest coastal lake. A Monmouth University-led study published in the journal Urban Naturalist finds that Deal Lake is locked in a seasonal cycle that sees the system loaded with nutrients in the cold winter and early spring months, fueling bursts of cyanobacteria growth in the summer and early fall.

Configuration of the STEREO experiment. Credit: Nature (2023). DOI: 10.1038/s41586-022-05568-2 After several years of operation, the STEREO collaboration published the final results of their antineutrino studies. With their data, the researchers excluded hints for the existence of sterile neutrinos, an additional neutrino state expected in many theories. The result, which appears in the January 11 issue of Nature, has important implications for many areas of fundamental physics.

Planetary defense and science to advance with new radar on a powerful telescope - Phys.org

science

With a transmitter less powerful than a microwave oven, a team of scientists and engineers has used the National Science Foundation's Green Bank Telescope (GBT) and Very Long Baseline Array (VLBA) to make the highest-resolution radar images of the moon ever collected from the ground, paving the way for a next-generation radar system to study planets, moons, and asteroids in the solar system.

Researchers develop superconducting flux qubits with unprecedented reproducibility

technology

Approximately two decades ago, it was shown theoretically that quantum computers could easily solve certain computationally demanding problems like factoring large numbers into prime numbers or searching efficiently in databases. These possibilities have triggered intense experimental efforts towards the physical realization of scalable quantum processors (such that it would be possible to increase the size of their quantum register).
