For the first time in Brazil, scientists have identified the presence of bacteria that cause columnaris disease, a serious disease in farmed fish intended for human consumption. Previously, different species of the genus Flavobacterium had only been detected in fish farms in Asia and the United States.
Finding water on the moon may only be a matter of detecting the right vibrations.
We know Mars has water ice in its polar regions, but astronauts (and their solar-powered equipment!) would much rather experience life closer to Mars' equator. As NASA looks toward landing humans on the red planet, the Planetary Science Institute (PSI) is mapping where water should and shouldn't be found and using statistics to quantify its certainty. Two new papers, led by PSI's Hanna Sizemore and Samuel Courville, highlight new global maps of subsurface water ice and identify the missions and tools needed to increase the certainty of the maps.
Grounding intermittent art festivals such as the Setouchi Triennale within the resource capacities and social thresholds of the island communities that host them is a path to the sustainable, long-term revitalization of these communities.
Recirculating aquaculture systems (RAS) are attracting growing attention as a sustainable aquaculture technology that can reduce water use, control rearing conditions and lower environmental impacts by filtering and reusing water. At the same time, RAS facilities rely on pumps, filters, aerators and other equipment that are often operated continuously or according to conservative fixed schedules, resulting in substantial electricity consumption to maintain stable rearing conditions.
The human genome contains more than 20,000 genes. However, at any given time and in a given cell, only a fraction are active. Researchers from EMBL Heidelberg's Krebs Group have developed an innovative experimental approach to understand how cells determine which genes to turn on and when.
Climate change, land-use change and socioeconomic pressures are turning wildfires from a primarily ecological process into a complex, systemic risk that cuts across ecosystems, infrastructure, public health, water resources, cultural heritage and rural livelihoods. Despite substantial investments in firefighting capacity, wildfires are projected to become more frequent, extreme and devastating, underscoring the need for cross-cutting solutions.
Every time a cell divides, it must accurately copy and distribute its DNA between two new cells. However, in some cases, chromosomes do not fully separate, leaving behind thin strands of DNA known as DNA bridges that connect the two newly formed cells.
A map showing the distribution of isotopes in Amazonian tree wood can help identify illegally harvested timber. By analyzing the ratio of different isotopes of elements such as oxygen, carbon, nitrogen and strontium, researchers can pinpoint the region where the wood was harvested more precisely. This helps combat the illegal timber trade.
The German eROSITA consortium (eROSITA-DE), which includes the University of Bonn and is led by the Max Planck Institute for Extraterrestrial Physics (MPE), has released its second major public data set, the "eROSITA Data Release 2" (DR2).
