Researchers demonstrate noise-free communication with structured light
Researchers at the University of the Witwatersrand (Wits) have outlined a new optical communication protocol that exploits spatial patterns of light for multi-dimensional encoding in a manner that does not require the patterns to be recognised, thus overcoming the prior limitation of modal distortion in noisy channels.
Proyecto One Sky lanza videos para planetarios destacando la importancia y la historia de la astronomia indigena

Estos videos, que recibieron reconocimientos en 2022 y 2023, ahora estan disponibles para descarga gratuita y pueden utilizarse en los planetarios de todo el mundo.
University of Minnesota theoretical physicists help expand the search for new particle
A team led by University of Minnesota Twin Cities physicists has discovered a new way to search for axions, hypothetical particles that could help solve some of nature's most puzzling mysteries.
Radiotelescopio de Kitt Peak se une a la red del gran Telescopio Event Horizon
En los ultimos anos, los cientificos del consorcio del Telescopio Event Horizon lograron obtener imagenes no solo de uno, sino de dos agujeros negros supermasivos utilizando una tecnica conocida como interferometria de muy larga base. Sin embargo, lograrlo no es para nada simple, y los futuros descubrimientos van a requerir mas potencia aun. Para lograrlo, un telescopio del Observatorio Nacional Kitt Peak se suma a esta mision.
The UArizona 12-meter Telescope at Kitt Peak Is Part of Something Much Bigger: the Event Horizon Telescope
In the past few years, scientists with the Event Horizon Telescope consortium have managed to successfully image not just one, but two supermassive black holes using a technique known as Very Long Baseline Interferometry. Doing so, however, is not a proverbial walk in the cosmic park, and future targets of discovery need even more power. To assist in this mission, a telescope at Kitt Peak National Observatory has also joined the fray.
Schrodinger's cat makes better qubits
Quantum computing uses the principles of quantum mechanics to encode and elaborate data, meaning that it could one day solve computational problems that are intractable with current computers.
Researchers tune thermal conductivity of materials 'on the fly' for more energy-efficient devices
A team led by University of Minnesota Twin Cities researchers discovered a new method for tuning the thermal conductivity of materials, achieving a record-high range of tunability that will open a door to developing more energy-efficient and durable electronic devices.
Researchers discover chemical evidence for pair-instability supernova from a very massive first star
The first stars illuminated the Universe during the Cosmic Dawn and put an end to the cosmic "dark ages" that followed the Big Bang. However, the distribution of their mass is one of the great unsolved mysteries of the cosmos.
David receives Joining and Welding Science Award
Stan David, retired scientist and Corporate Fellow Emeritus at the Department of Energy's Oak Ridge National Laboratory, was awarded the Joining and Welding Science Award from the Joining and Welding Research Institute at Osaka University, Japan.
New study describes unique jet structure of brightest gamma-ray burst ever
When scientists detected the gamma-ray burst known as GRB 221009A on October 9, 2022, they dubbed it the BOAT, or the brightest-of-all-time. Now, scientists studying GRB 221009A describe an unusual structure to the jet of material expelled during the explosion that may explain GRB 221009A's extreme nature and why its afterglow remained visible for so long after the event.
Calculation Shows Why Heavy Quarks Get Caught up in the Flow
Theorists have calculated how quickly a melted soup of quarks and gluons--the building blocks of protons and neutrons--transfers its momentum to heavy quarks. The calculation will help explain experimental results showing heavy quarks getting caught up in the flow of matter generated in heavy ion collisions.

Precision Nuclear Physics in Indium-115 Beta Decay Spectrum using Cryogenic Detectors
Nuclei such as Indium-115 (In-115) are extremely long lived, with half-lives of more than 100 billion years. These nuclei allow scientists to probe elusive high energy nuclear states. In a new study, scientists theoretically determined the electron energy spectrum from decays of In-115 based on data collected in a specialized detector. The scientists also performed the world's most precise measurement of the half-life of In-115.
Quantum computers are better at guessing, new study demonstrates
Daniel Lidar, the Viterbi Professor of Engineering at USC and Director of the USC Center for Quantum Information Science & Technology, and first author Dr. Bibek Pokharel, a Research Scientist at IBM Quantum, achieved this quantum speedup advantage in the context of a "bitstring guessing game." They managed strings up to 26 bits long, significantly larger than previously possible, by effectively suppressing errors typically seen at this scale. (A bit is a binary number that is either zero or one).
