Do some mysterious bones belong to gigantic ichthyosaurs?      (via sciencedaily.com)     Original source 

Several similar large, fossilized bone fragments have been discovered in various regions across Western and Central Europe since the 19th century. The animal group to which they belonged is still the subject of much debate to this day. A study could now settle this dispute once and for all: The microstructure of the fossils indicates that they come from the lower jaw of a gigantic ichthyosaur. These animals could reach 25 to 30 meters in length, a similar size to the modern blue whale.

A smarter city skyline for flood safety      (via sciencedaily.com)     Original source 

With climate change and rising urbanization, the likelihood and severity of urban flooding are increasing. But not all city blocks are created equal. Researchers investigated how urban layout and building structures contribute to pedestrian safety during flooding. Based on their simulated results, the team recommends modifying building corners and protective block layouts to reduce pedestrian risk.

A natural touch for coastal defense      (via sciencedaily.com)     Original source 

Common 'hard' coastal defenses, like concrete sea walls, might struggle to keep up with increasing climate risks. A new study shows that combining them with nature-based solutions could, in some contexts, create defenses which are better able to adapt.

Atmospheric and economic drivers of global air pollution      (via sciencedaily.com)     Original source 

Carbon monoxide emissions from industrial production have serious consequences for human health and are a strong indicator of overall air pollution levels. Many countries aim to reduce their emissions, but they cannot control air flows originating in other regions. A new study looks at global flows of air pollution and how they relate to economic activity in the global supply chain.

Boreal forest and tundra regions worst hit over next 500 years of climate change, study shows      (via sciencedaily.com)     Original source 

Modelling climate change over a 500 year period shows that much of the boreal forest, the Earth's northernmost forests and most significant provider of carbon storage and clean water, could be seriously impacted, along with tundra regions, treeless shrublands north of the boreal forest that play a significant role in regulating the Earth's climate.

New four-terminal tandem organic solar cell achieves 16.94% power conversion efficiency      (via sciencedaily.com)     Original source 

Researchers have fabricated a new four-terminal organic solar cell with a tandem configuration with a 16.94% power conversion efficiency (PCE). The new device is composed by a highly transparent front cell that incorporates a transparent ultrathin silver (Ag) electrode of only 7nm, which ensures its efficient operation.

Using pulp and paper waste to scrub carbon from emissions      (via sciencedaily.com)     Original source 

Researchers have come up with an innovative approach to improve the energy efficiency of carbon conversion, using waste material from pulp and paper production. The technique they've pioneered not only reduces the energy required to convert carbon into useful products, but also reduces overall waste in the environment.

PFAS 'forever chemicals' above drinking water guidelines in global source water      (via sciencedaily.com)     Original source 

PFAS (aka 'forever chemicals') are notoriously difficult to destroy. They've been linked to environmental and health issues, including some cancers, but a lot remains unknown about the true scale and potential impacts of the problem -- including how much is in our water supply. A new study assessed the levels of PFAS contamination in surface and ground water around the globe -- and found that much of our global source water exceeds PFAS safe drinking limits.
