Muons are particles used to study fundamental physics and to image large structures such as volcanoes, bridges and ancient buildings. But despite their apparent benefits to science – and even society more broadly – muons only have a half-life of around one microsecond. Now researchers at the University of Plymouth have suggested a means of overcoming that, using intense laser pulses to reduce the rate of decay and at least double the muon’s lifetime.

Floating offshore wind turbines (FOWTs) operate under complex ocean conditions, where currents generate vortex shedding that can trigger platform oscillation, affecting turbine safety and energy output. This study uses high-fidelity computational fluid dynamics (CFD) to explore how different flow incidence angles (0°, 90°, 180°) influence the vortex-induced motion (VIM) of a semi-submersible FOWT platform. Results show clear differences in surge, sway, and yaw responses when the current direction changes, with strong lock-in behavior occurring at reduced velocity V_R = 6–10. The work highlights how pontoons and cross braces suppress VIM amplitudes by disturbing the wake patterns. The findings provide valuable insight for improving design safety and optimizing hydrodynamic performance of FOWT platforms.

A new study published in Big Earth Data evaluates ten satellite-based and reanalysis precipitation datasets available in Google Earth Engine using rain gauge observations across Czechia from 2001 to 2021. The results show that the gauge-adjusted GSMaP dataset provides the highest overall accuracy, while ERA5-Land performs well for long-term analyses despite systematic overestimation. The findings offer clear guidance for selecting reliable precipitation datasets for hydrological, climate, and environmental applications, particularly in regions with complex terrain.

New University of Hawaiʻi research confirms that “Sharktober” is real, revealing a statistically significant spike in shark bite incidents in Hawaiian waters every October. The study, which analyzed 30 years of data (1995–2024), found that about 20% of all recorded bites occurred in that single month, a frequency far exceeding any other time of the year. Researchers at UH Mānoa’s Hawai‘i Institute of Marine Biology (HIMB) Shark Lab published their findings in Frontiers in Marine Science.

Using in situ liquid-phase transmission electron microscopy under conditions that excluded the influence of dissolved oxygen and electron beams, scientists have achieved the first nanoscale, real-time observation of the reaction between pyrite and gold-bearing solutions, providing critical insights into gold enrichment by pyrite.

Space debris poses a risk to humans when it falls out of orbit and plunges toward the ground, but can be difficult to track after entering the Earth's atmosphere. Using already established networks of earthquake-detecting seismometers, scientists have developed a new tracking method that generates more detailed information in near real-time than authorities have today—information that will help to quickly locate and retrieve the charred and sometimes toxic remains.
