A new quantum device could one day help spacecraft travel beyond Earth's orbit or aid submarines as they navigate deep under the ocean with more precision than ever before.

Scientists analyzing data from NASA’s CODEX (Coronal Diagnostic Experiment) investigation have successfully evaluated the instrument’s first images, revealing the speed and temperature of material flowing out from the Sun. These images, shared at a press event Tuesday at the American Astronomical Society meeting in Anchorage, Alaska, illustrate the Sun’s outer atmosphere, or corona, is not a homogenous, steady flow of material, but an area with sputtering gusts of hot plasma. These images will help scientists improve their understanding of how the Sun impacts Earth and our technology in space.

The NEAL team at the University of South China has successfully developed HARMONY2.0, an upgraded version of their higher-order modes diffusion code HARMONY1.0. By adopting a hybrid two-step methodology combining MC(Monte Carlo) homogenization and deterministic higher-order modes calculation, this advancement addresses the limitations of deterministic methods in handling complex geometries and energy spectrum adaptation, while avoiding the computational inefficiency inherent to MC approaches. The integration of OpenMP-based parallel computing further accelerates the process, significantly enhancing the capability for reactor higher-order modes analysis. This progress provides critical technical support for key applications such as reactor reactivity measurements and online monitoring.

Over the past decade, the fast-growing seaweed Caulerpa prolifera has taken over seagrass in Florida’s Indian River Lagoon. While this seaweed provides some habitat, it supports fewer marine species than the original seagrass, signaling a decline in biodiversity. Now, scientists are closely monitoring an unexpected player: small, green sap-sucking sea slugs that feed on C. prolifera and have surged in number. Their presence is prompting new questions about habitat loss, potential pathways for ecosystem recovery, and the uncertain future of marine life in a seagrass-depleted environment.
