On 19 March 2025, the European Space Agency’s Euclid mission released its first batch of survey data, including a preview of its deep fields. Here, hundreds of thousands of galaxies in different shapes and sizes take centre stage and show a glimpse of their large-scale organisation in the cosmic web.

Waste-to-nutrition" technologies aim to transform agricultural or food waste into ingredients for human and animal consumption, while reducing the environmental impact of food systems. INRAE scientists assessed the environmental impact of 5 of these technologies in nine usage scenarios in France. They compared them with existing waste recovery technologies such as anaerobic digestion and composting. Their results, published in Nature Sustainability, show that these new technologies do not systematically provide any environmental benefits compared with existing solutions.

For years, post-traumatic stress disorder (PTSD) has been studied primarily in people who experience trauma firsthand. But what about those who witness it — military veterans, first responders, health care workers, or bystanders to violence — who constitute 10 percent of all PTSD cases?

New research from Virginia Tech, published in PLOS ONE, reveals that witnessing trauma triggers unique brain changes, distinct from those caused by experiencing trauma firsthand. The study is the first to shed light on the molecular differences between directly acquired PTSD and bystander PTSD and could pave the way for changes in how the disorders are treated.

Mathematicians from New York University and the University of British Columbia have resolved a decades-old geometric problem, the Kakeya conjecture in 3D, which studies the shape left behind by a needle moving in multiple directions.

In their ongoing efforts to push the boundaries of quantum possibilities, physicists at WashU have created a new type of “time crystal,” a novel phase of matter that defies common perceptions of motion and time.
