Strengthening El Nino 'adding fuel to a planet already on fire': UN chief‎

A strengthening El Niño that could shatter all-time records is "adding fuel to a planet already on fire" and pushing the world into "uncharted territory," U.N. Secretary-General Antonio Guterres warned Friday.

Fish pathogens once limited to Asia and US emerge in Brazilian farms‎

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.

Laying odds on the potential for Martian water near future landing zones‎

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.

Smarter fish farms could cut electricity use and CO₂ while keeping fish safe‎

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.

A new genetic tool helps researchers uncover the logic of gene regulation‎

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.
