In hot water: Coral resilience in the face of climate change      (via sciencedaily.com)     Original source 

Researchers have been studying the effects of climate change on coral reefs. Monitoring two coral species off the coast of Hawaii, one team found that local adaptations in response to near-severe heat stress allowed certain populations to endure such events.

Acidity of Antarctic waters could double by century's end, threatening biodiversity      (via sciencedaily.com)     Original source 

Without drastically reducing global emissions, the Antarctic Ocean could become too acidic for hundreds of species living there, many already endangered by rising temperatures and sea ice loss.

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.

The rock that creates clouds      (via sciencedaily.com)     Original source 

Felspar dust in the air can create clouds. The feldspar particles act as nucleation sites to which water molecules can attach extremely efficiently. Why this is the case has remained a mystery for a long time. Scientists have now studied feldspar using a special atoimic force microscope and managed to explain this remarkable property of feldspar on an atomic level. The atomic structure is just right to create a layer of OH-groups which in turn can connect to water molecules perfectly.

Scientists outline a bold solution to climate change, biodiversity loss, social injustice      (via sciencedaily.com)     Original source 

An international team of scientists has used a novel 500-year dataset to frame a 'restorative' pathway through which humanity can avoid the worst ecological and social outcomes of climate change.

Global study of extreme drought impacts on grasslands and shrublands      (via sciencedaily.com)     Original source 

A global study shows that the effects of extreme drought -- which is expected to increase in frequency with climate change -- has been greatly underestimated for grasslands and shrublands. The findings quantify the impact of extreme short-term drought on grassland and shrubland ecosystems across six continents with a level of detail that was not previously possible. It is the first time an experiment this extensive has been undertaken to generate a baseline understanding of the potential losses of plant productivity in these vital ecosystems.

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.

Fastest swimming insect could inspire uncrewed boat designs      (via sciencedaily.com)     Original source 

Whirligig beetles, the world's fastest-swimming insect, achieve surprising speeds by employing a strategy shared by fast-swimming marine mammals and waterfowl, according to a new study that rewrites previous explanations of the physics involved.

The snail or the egg?      (via sciencedaily.com)     Original source 

Animals reproduce in one of two distinct ways: egg-laying or live birth. By studying an evolutionarily recent transition from egg-laying to live-bearing in a marine snail, collaborative research has shed new light on the genetic changes that allow organisms to make the switch.

The choreography connecting kelp forests to the beach      (via sciencedaily.com)     Original source 

A new study uncovers a symphony of synchrony between the kelp forest and beach, with broader implications for the beach food web as the climate changes.

Seismic and infrasonic signals used to characterize Nord Stream pipeline events      (via sciencedaily.com)     Original source 

A new study provides further evidence that the Nord Stream seismic signals came from a complex source. The signals lasted longer than would be expected from a single explosive source, the researchers say, and were more like the signals detected from an underwater volcano or a pipeline venting gas.

'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.

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.
