The XRISM science team, including members from Nagoya University in Japan, has explained how a galaxy cluster maintains its heat, despite emitting X-rays that cool the hot gas at its center. The group discovered the existence of a fast-moving, high-temperature gas flow in the center of the Centaurus cluster. The result suggests how the cool down of the hot gas is avoided and why clusters look like they do.

Irvine, Calif., May 1, 2025 — University of California, Irvine scientists have expanded on a longstanding model governing the mechanics behind slip banding, a process that produces strain marks in metals under compression, gaining a new understanding of the behavior of advanced materials critical to energy systems, space exploration and nuclear applications.

Increased vegetation growth in European mountains, driven by climate and land use changes, reduces genetic diversity of medicinal plants, as shown by a new study using satellite data and genetic analyses on Greek mountain tea.

Researchers at the University of Tsukuba estimated Japan's spring leaf flush dates in recent years using data from the Second-generation Global Imager (SGLI) sensor onboard the Japan Aerospace Exploration Agency's (JAXA) Global Change Observation Mission-Climate (GCOM-C) satellite. Their analysis revealed that in 2023 and 2024, years characterized by exceptionally high spring temperatures, leaf flush occurred significantly earlier than usual, indicating that elevated temperatures linked to climate change are affecting Japanese ecosystems.
