Healthy reef sounds can boost coral and fish recovery efforts‎

Coral reefs are renowned for their visual beauty, but for the marine life they support, their sounds may be just as enticing. Two new studies led by UC San Diego's Scripps Institution of Oceanography reveal how underwater acoustic enrichment—the playback of sounds from healthy reefs—can help spur the recovery of degraded coral reefs and their fish communities.

Solar Orbiter tracks origin of mysterious magnetic switchbacks‎

The European Space Agency–led Solar Orbiter spacecraft has flown through an S-shaped kink known as a "switchback" in the solar wind's magnetic field. By fingerprinting the elusive particles within the switchback, Solar Orbiter has traced its origin back to the sun's surface and revealed more about solar magnetism—the unruly instigator of dangerous solar storms.

Working around men may make women feel worse about mistakes, study finds‎

We all make them, and we all make them at work: Mistakes on the job happen regardless of line of work, experience or gender. How employees feel about them and how they are perceived by others, however, differs. Women are more likely than men to perceive mistakes negatively—but this depends on whom they share the office with, a new study in Frontiers in Organizational Psychology has shown.

Listening to hidden insects could give farmers an early warning of crop pests‎

Crawling through muddy soybean fields to inspect several plant-mounted microphones was not on Emily Sur's graduate school bingo card, but she's not mad about it. Her research offers a unique opportunity to work at the intersection of entomology, agriculture and emerging technologies while still doing what she loves.

AI chatbots endorse existing climate-related policies twice as often as new proposals‎

A new study of multiple large language models (LLMs) found that when users asked chatbots for advice, the chatbots were more likely to make suggestions that favor the status quo over alternatives. The tendency of artificial intelligence to default to more common advice could be bad news for the climate.

Emotional ties to cultural heritage show strongest link to digital museum engagement‎

Museums are increasingly using digital technologies to create more interactive and accessible experiences for visitors. Technologies such as three-dimensional (3D) digital models, virtual reality (VR) and augmented reality (AR) allow visitors to explore artifacts in new ways, both online and during visits to physical museums.
