Emergency department visits increased during and after Aliso Canyon gas blowout‎

Emergency department use rose significantly during and after the 2015–16 Aliso Canyon gas blowout, according to a new paper from the UCLA Aliso Canyon Disaster Health Research Study. Data showed that people living downwind of the blowout had 26 more emergency department visits per 1,000 residents from before to during the disaster, compared with the same time frame in a demographically similar comparison community. That surge remained similarly high a year later.

Floating litter extends over Chesapeake Bay, the largest estuary in the US‎

A study led by researchers from the Smithsonian Institution and the UB reveals that reducing single-use plastic is essential for protecting coastal ecosystems. Floating litter has also invaded Chesapeake Bay, the largest estuary in the United States and one of the most important in the world.

Study advocates cross-tier traceability to improve food safety‎

The Hong Kong SAR imports more than 90% of its food, and it can be very difficult, when food safety incidents occur, to trace the source across a complex supply chain. Prof. Leng Mingming, dean of the Faculty of Business and chair professor of operations and risk management at Lingnan University, has published a new study proposing the introduction of a unified product tracing system across the food supply chain.

Molecular fossils reveal secrets of Earth's recovery from ancient global warming event‎

Scientists have uncovered new evidence from one of Earth's most extreme ancient warming events, revealing how the climate may recover long after human-driven CO2 emissions cease.

Atlantic and Pacific may follow different rules on long-term warming, analysis shows‎

Florida State University researchers have identified key differences in the root causes of long-term sea-surface temperature changes across the Atlantic and Pacific oceans, a finding that could help guide future research on ocean variability. The study by Assistant Professor of meteorology Michael Diamond and FSU meteorology graduate alumnus Anthony Freveletti found that long-term temperature changes in the Pacific Ocean are driven primarily by internal ocean variability, while those in the Atlantic are largely the result of human emissions.

Study finds urbanization in the Hong Kong Greater Bay Area intensifies extreme heat and heavy rainfall risks‎

In recent years, Hong Kong has experienced repeated episodes of intense rainfall that have significantly affected social operations, including the "once-in-a-century" rainstorm in September 2023, exceptionally heavy rain in May 2024, and a series of Black Rainstorm events in early August 2025. These extreme weather events have not only disrupted residents' daily travel and public infrastructure but also highlighted the challenges faced by high-density coastal cities in coping with extreme weather.

Seaweed farming offers climate benefits, but regulatory gaps pose risks‎

From sea lettuce adorning tidal pools and bull kelp left in windrows at the high tide line to towering underwater forests of giant kelp providing refuge and food for countless species, British Columbia's seaweeds are both prominently visible along shorelines and hidden from sight in the deep.

Mars mission simulations reveal key to teamwork under pressure‎

Whether it's to the moon or Mars, a NASA mission requires some essential preparations: designing and developing the spacecraft, astronaut training and safety checks, clear goals, and strategies and procedures for maintaining communication between crews on Earth and in space.

Superconducting TES array X-ray spectrometer goes into operation at BESSY II‎

Europe's first and only TES spectrometer at a synchrotron source is now in operation at BESSY II, developed within a collaboration between the HZB, the MPI-CEC (Mühlheim-an-der-Ruhr, Germany) and the NIST (Boulder, Colorado, U.S.). The photon detection efficiency of the new instrument exceeds that of wavelength-dispersive X-ray emission spectrometers by a factor of 100 to 1,000. It will be used to investigate the electronic properties of atomically thin layers, nanostructures and highly diluted atomic and molecular samples. The team is looking forward to receiving exciting research proposals from the user community.
