Deep in the ocean, brown algae and diatoms produce a complex carbohydrate molecule called fucoidan, which helps form their protective outer layers. The fucoidan molecule is very difficult for microbes to break down because its chemical structure may include dozens of different linkages and branching patterns that vary from one algal species to another.

Launched on Oct. 20, 2018, the joint ESA/JAXA BepiColombo mission has traveled for almost eight years, using a carefully planned but eventful sequence of planetary flybys and solar-electric propulsion to gradually approach its destination, Mercury. The mission is now entering the final stage of its journey to the smallest and innermost planet of our solar system.

The historic droughts of 2023 and 2024 in the Amazon reduced river flows and altered the region's rainfall composition. Daily monitoring in Manaus, the capital of the Brazilian state of Amazonas, revealed these changes through the use of isotopes, which act as a kind of water "fingerprint." This method demonstrated how El Niño and warming in the North Atlantic affected the origin of moisture and precipitation dynamics.

After an eight-year journey, a spacecraft carrying European and Japanese probes began the monthslong, high-risk approach to Mercury on Thursday to study the sun-scorched planet.

El Niño is firmly established and will intensify into a very strong event in the coming months, with major impacts on rainfall and temperature patterns and associated risks of floods, drought and extreme heat, according to a new update from the World Meteorological Organization (WMO).
