XXP instrument back online, marking a key milestone in high-energy upgrade to SLAC's X-ray laser‎

XPP, the X-ray Pump Probe instrument at the Linac Coherent Light Source (LCLS), is back online and welcoming researchers after a complete rebuild. The overhaul has readied XPP for the significant increase in X-ray output expected from the ongoing high-energy upgrade to LCLS at the Department of Energy's SLAC National Accelerator Laboratory. LCLS is a pioneering X-ray free-electron laser facility used by scientists around the world to capture ultrafast snapshots of natural processes.

Room-temperature multiferroic could pave way to low-energy computing‎

A team of researchers at Rice University has engineered a new version of a well-known multiferroic that exhibits orders of magnitude higher performance at room temperature than its parent material. The study, published in the Proceedings of the National Academy of Sciences, describes a modified version of bismuth ferrite that shows a 10-fold increase in magnetization and 100-fold increase in magnetoelectric coupling compared to standard varieties.

Rap fans share the bad rap in court‎

An innovative James Cook University experiment has found rap-related cues shape how people judge a hypothetical fan accused of violent crime, raising questions about the use of lyrics as evidence in court. James Cook University psychology senior lecturer Amanda Krause, who coauthored the study published in the Psychology of Music, said almost half of the top 50 most-streamed artists are classified as hip-hop or rap.

Perceptions of cultural foreignness may lead to job discrimination, study finds‎

Asian, Arab and Latino Americans may face more discrimination when seeking jobs that emphasize stereotypically American characteristics because they are deemed to be culturally foreign, according to research published in the Journal of Experimental Psychology

Western US is fending off more fires before they start—and still getting hit by its biggest blazes yet‎

The number of wildfires burning in the Western United States each year dropped roughly 28% over the past three decades, even as annual burned area and damage from wildfires have soared. A decline in fires accidentally sparked by humans accounts for over 40% of the overall trend, according to a new study.

New study finds urban parks in less privileged neighborhoods are smaller, hotter and more polluted‎

A new study from researchers at George Washington University Milken Institute of Public Health reveals that not all urban parks provide equal health benefits. Parks in less privileged neighborhoods across the United States tend to be smaller, hotter, and more polluted than those in wealthier areas—highlighting persistent environmental inequities in cities nationwide. The work is published in the journal Environmental Research Letters.

GP Com observations sharpen picture of a rare ultracompact binary system‎

Using the Rozhen National Astronomical Observatory, Bulgarian astronomers have conducted optical photometric observations of an ultracompact binary known as GP Com. Results of the observational campaign, presented in the Proceedings of the Bulgarian Academy of Sciences, shed more light on the properties of this system.

ESA's Proba 3 is unlocking secrets of the solar wind‎

It has been a dream of astronomers and solar scientists for ages. A new mission gives solar researchers a powerful new tool in their arsenal: on-demand, total solar eclipses. Launched in 2024, The European Space Agency's Proba-3 mission has proven the feasibility of a free-flying, space-based coronagraph. Now, the first science results from the mission are giving us a view of the origin of space weather. The results were recently published in The Astrophysical Journal Letters.

Alternative work arrangements spur new thinking on the role of HR professionals‎

Employee work arrangements are a challenge for management globally, with effects on employees' experiences and the success of organizations. In an editorial in The International Journal of Human Resource Management, researchers highlight the critical role of human resources (HR) professionals in dealing with alternative work arrangements. In so doing, they seek to spur new thinking and evidence on HR's role in the context of such arrangements.

Frozen-in gravity: A new way to understand the evolution of spacetime dynamics‎

The concept of spacetime, first described in Einstein's theory of general relativity, has since been widely studied by many physicists worldwide. Spacetime is described mathematically as a four-dimensional (4D) continuum in which physical events occur, which merges three-dimensional (3D) space, with one-dimensional (1D) time.
