Along the coast, waves break with a familiar sound. The gentle swash of the surf on the seashore can lull us to sleep, while the pounding of storm surge warns us to seek shelter.

Yet these are but a sample of the sounds that come from the coast. Most of the acoustic energy from the surf is far too low in frequency for us to hear, traveling through the air as infrasound and through the ground as seismic waves. 

Scientists at UC Santa Barbara have recently characterized these low-frequency signals to track breaking ocean waves. In a study published in Geophysical Journal International, they were able to identify the acoustic and seismic signatures of breaking waves and locate where along the coast the signals came from. The team hopes to develop this into a method for monitoring the sea conditions using acoustic and seismic data.

A new $1.39 million grant from the National Science Foundation (NSF) will upgrade Georgia State University’s CHARA Array, giving it the ability to observe stars across the full visible and near-infrared spectrum.

An international team led by Dr. Hila Glanz of the Technion – Israel Institute of Technology has uncovered a new origin for hypervelocity white dwarfs — stellar remnants racing through space at more than 2000 km/s.

Using advanced 3D hydrodynamic simulations, the researchers showed that when two rare hybrid white dwarfs merge, the heavier star can undergo a double-detonation explosion. This blast ejects the surviving remnant of its companion at hypervelocity, fast enough to escape the Milky Way.

The findings, published in Nature Astronomy, explain both the extreme speeds and unusual properties of known hypervelocity white dwarfs, while also pointing to a new pathway for faint and peculiar Type Ia supernovae.

The study was conducted by researchers from the Technion, Universität Potsdam, and the Max Planck Institute for Astrophysics, and has implications for future transient surveys and Gaia discoveries.

After six centuries in Spain, discrimination against the Roma people remains “rooted in stereotypes based on ignorance and, in some cases, pseudo-knowledge about this community”, explains Juan Jarque Jarque, who advocates for an inclusive education system that respects diverse values as a way to end antigypsyism and encourage greater Roma participation in community life. To overcome both antigypsyism in Spanish society and Roma disengagement from it, Jarque proposes an education system that weaves Roma history into Spain’s national narrative while also protecting each community’s cultural identity. This way, different groups can preserve their traditions yet share the same cultural, political and social space.

In 2015, NASA launched an unusual and brilliant exoplanet outreach campaign, offering retro-style posters, virtual guided tours, and even coloring books. The project quickly went viral worldwide. What explains the success of a campaign about a relatively young field of science that—unlike other areas of space research—lacks spectacular imagery?

Ceridwen Dovey, science communicator, writer, filmmaker, and researcher, has just published in the Journal of Science Communication (JCOM) a Practice Insight paper that presents a case study focusing on the Exoplanet Travel Bureau’s poster campaign. Dovey describes the productive working relationships between scientists and artists that produced this standout work and shows how, in contexts like this, artists are not merely in service to science but can also inspire research itself and help scientists clarify their own thinking.

For the first time, the famous “spirograph” Planetary Nebula IC418’s non-explosive stellar evolution has been captured over an unprecedented period of 130 years—almost double the length of a typical human lifetime. These results have recently published in the prestigious Astrophysical Journal Letters by Professor Albert ZIJLSTRA, Professor of Astrophysics at The University of Manchester, and Professor Quentin PARKER, Director of the Laboratory for Space Research at The University of Hong Kong.

A new study co-led by Professor Dazhi XI, climatologist from the Department of Earth and Planetary Sciences at The University of Hong Kong (HKU), and Zheng-Hang FU, a Ph.D. student from Fudan University reveals that over the past decades, clustered tropical cyclone—storms that occur in close succession—are becoming less frequent in the Northwestern Pacific, including Hong Kong, Japan, and the Philippines, while becoming more common in the North Atlantic, affecting regions such as the U.S. East Coast and the Caribbean. The study, titled “Shifting Hotspot of Tropical Cyclone Clusters in a Warming Climate,” was recently published in Nature Climate Change.
