Half a billion-year-old spiny slug reveals the origins of mollusks      (via sciencedaily.com)     Original source 

Exceptional fossils with preserved soft parts reveal that the earliest mollusks were flat, armored slugs without shells. The new species, Shishania aculeata, was covered with hollow, organic, cone-shaped spines. The fossils preserve exceptionally rare detailed features which reveal that these spines were produced using a sophisticated secretion system that is shared with annelids (earthworms and relatives).

Research catalogs greenhouse gas emissions tied to energy use for interbasin water transfers      (via sciencedaily.com)     Original source 

Much of the water in the West is transported across vast geographical areas by large infrastructure projects known as interbasin water transfers. Two of these projects in particular make up 85% of all energy-related greenhouse gas emissions associated with U.S. interbasin transfers -- one in Arizona and the other in California -- according to the new research.

Green hydrogen: 'Artificial leaf' becomes better under pressure      (via sciencedaily.com)     Original source 

Hydrogen can be produced via the electrolytic splitting of water. One option here is the use of photoelectrodes that convert sunlight into voltage for electrolysis in so called photoelectrochemical cells (PEC cells). A research team has now shown that the efficiency of PEC cells can be significantly increased under pressure.

Bold moves needed for California agriculture to adapt to climate change      (via sciencedaily.com)     Original source 

California needs urgent and bold measures to adapt its $59 billion agriculture sector to climate change as the amount of water available for crops declines, according to a new report. The report provides a roadmap for more water capture, storage, and distribution systems that are in harmony with climate projections and ecosystems. It further considers how runoff and groundwater can be used repeatedly as it flows generally from mountainsides to coastal lands.

Plant-inspired polymers for water purification      (via sciencedaily.com)     Original source 

Researchers have synthesized a bio-inspired polymer for water purification. The polymer was designed to mimic phytochelatin, a plant protein that selectively captures and neutralizes harmful heavy metal ions. The hyperconfinement of the polymer enabled a flow-through system and effectively removed cadmium ions from contaminated water, making it safe to drink. The system was selective for heavy metals and provides a new way to remove specific contaminants from water.

Nitrogen emissions have a net cooling effect: But researchers warn against a climate solution      (via sciencedaily.com)     Original source 

An international team of researchers has found that nitrogen emissions from fertilizers and fossil fuels have a net cooling effect on the climate. But they warn increasing atmospheric nitrogen has further damaging effects on the environment, calling for an urgent reduction in greenhouse gas emissions to halt global warming.
