Green ammonia could decarbonize 60% of global shipping when offered at just 10 regional fuel ports      (via sciencedaily.com)     Original source 

A study has found that green ammonia could be used to fulfill the fuel demands of over 60% of global shipping by targeting just the top 10 regional fuel ports. Researchers looked at the production costs of ammonia which are similar to very low sulphur fuels, and concluded that the fuel could be a viable option to help decarbonize international shipping by 2050.

Stranger than friction: A force initiating life      (via sciencedaily.com)     Original source 

As the potter works the spinning wheel, the friction between their hands and the soft clay helps them shape it into all kinds of forms and creations. In a fascinating parallel, sea squirt oocytes (immature egg cells) harness friction within various compartments in their interior to undergo developmental changes after conception.

Is natural spa water a fossil of water? Uncover the real ultra-deep water cycles      (via sciencedaily.com)     Original source 

Researchers have made a groundbreaking discovery regarding the origins of non-meteoric water in natural spa waters located in central Japan. Based on numerical modeling, their results suggest that this water has been confined within the lithosphere for an extensive period of 1.5-5 million years. They identified three primary sources for this ancient water: the Philippine Sea Plate, the Pacific Plate, and ancient seafloor sediments, particularly in the Niigata and southwest Gunma regions.

Life span increases in mice when specific brain cells are activated      (via sciencedaily.com)     Original source 

A new study identifies, in mice, a critical communication pathway connecting the brain and the body's fat tissue in a feedback loop that appears central to energy production throughout the body. The research suggests that the gradual deterioration of this feedback loop contributes to the increasing health problems that are typical of natural aging.

Protecting coral 'nurseries' as important as safeguarding established coral reefs      (via sciencedaily.com)     Original source 

New research in the southwestern part of Hawai'i Island shows that identifying and protecting marine ecosystems both down-current and up-current of coral reefs, specifically areas where coral larvae are more likely to survive and thrive, is crucial to future coral conservation and restoration efforts -- especially as reefs face increasing pressure from the devastating effects of climate change.

Protected areas for elephants work best if they are connected      (via sciencedaily.com)     Original source 

The largest analysis yet of African savannah elephant populations shows that conservationists have successfully protected elephants in southern Africa for the last 25 years. However, the pattern varies regionally, with some elephant populations soaring and others still facing large declines. The key to long-term stability appears to be connecting large core areas with neighboring buffer zones, as opposed to well-protected but isolated protected areas known as 'fortress conservation.'

Advancing the generation of in-vivo chimeric lungs in mice using rat-derived stem cells      (via sciencedaily.com)     Original source 

Creating a functional lung using interspecies chimeric animals is an attractive albeit challenging option for lung transplantation, requiring more research on the viable conditions needed for organ generation. A new study uses reverse-blastocyst complementation and tetraploid-based organ complementation methods to first determine these conditions in lung-deficient mice and then to generate rat-derived lungs in these mice. It provides useful insights on the intrinsic species-specific barriers and factors associated with lung development in interspecies chimeric animals.

New roles for autophagy genes in cellular waste management and aging      (via sciencedaily.com)     Original source 

Autophagy, which declines with age, may hold more mysteries than researchers previously suspected. Scientists have now uncovered possible novel functions for various autophagy genes, which may control different forms of disposal including misfolded proteins -- and ultimately affect aging.

Nematode proteins shed light on infertility      (via sciencedaily.com)     Original source 

Biologists developed a method for illuminating the intricate interactions of the synaptonemal complex in the nematode C. elegans. The authors identified a trio of protein segments that guide chromosomal interactions, and pinpointed the location where they interact with each other. Their novel method uses a technique known as genetic suppressor screening, which can serve as a blueprint for research on large cellular assemblies that resist traditional structural analysis.

'Giant' predator worms more than half a billion years old discovered in North Greenland      (via sciencedaily.com)     Original source 

Fossils of a new group of animal predators have been located in the Early Cambrian Sirius Passet fossil locality in North Greenland. These large worms may be some of the earliest carnivorous animals to have colonized the water column more than 518 million years ago, revealing a past dynasty of predators that scientists didn't know existed.

Evolution might stop humans from solving climate change      (via sciencedaily.com)     Original source 

Human culture has evolved to allow humans to extract resources and helped us expand to dominate the biosphere. But the same evolutionary processes may counteract efforts to solve new global environmental threats like climate change, according to a new study. Tackling the climate crisis will require worldwide regulatory, technical and economic systems supported by strong global cooperation. However, this new study concludes that the group-level processes characteristic of human cultural evolution, will cause environmental competition and conflict between sub-global groups, and work against global solutions. Adapting to climate change and other environmental problems will, therefore, require human evolution to change.

Understanding climate mobilities: New study examines perspectives from South Florida practitioners      (via sciencedaily.com)     Original source 

A recent study assessed the perspectives of 76 diverse South Florida climate adaptation professionals. A new study explores the expectations and concerns of practitioners from the private sector, community-based organizations, and government agencies about the region's ability to adapt in the face of increasing sea level rise and diverse consequences for where people live and move, also known as climate mobility.

From NYC to DC and beyond, cities on the East Coast are sinking      (via sciencedaily.com)     Original source 

Major cities on the U.S. Atlantic coast are sinking, in some cases as much as 5 millimeters per year -- a decline at the ocean's edge that well outpaces global sea level rise, confirms new research. Particularly hard hit population centers such as New York City and Long Island, Baltimore, and Virginia Beach and Norfolk are seeing areas of rapid 'subsidence,' or sinking land, alongside more slowly sinking or relatively stable ground, increasing the risk to roadways, runways, building foundations, rail lines, and pipelines, according to a new study.
