Caribbean seagrasses provide services worth $255B annually, including vast carbon storage, study shows      (via sciencedaily.com)     Original source 

Caribbean seagrasses provide about $255 billion in services to society annually, including $88.3 billion in carbon storage, according to a new study. The study has put a dollar value on the many services -- from storm protection to fish habitat to carbon storage -- provided by seagrasses across the Caribbean, which holds up to half the world's seagrass meadows by surface area and contains about one-third of the carbon stored in seagrasses worldwide.

Bridging traditional economics and econophysics      (via sciencedaily.com)     Original source 

How do asset markets work? Which stocks behave similarly? Economists, physicists, and mathematicians work intensively to draw a picture but need to learn what is happening outside their discipline. A new paper now builds a bridge.

These long-necked reptiles were decapitated by their predators, fossil evidence confirms      (via sciencedaily.com)     Original source 

In the age of dinosaurs, many marine reptiles had extremely long necks compared to reptiles today. While it was clearly a successful evolutionary strategy, paleontologists have long suspected that their long-necked bodies made them vulnerable to predators. Now, after almost 200 years of continued research, direct fossil evidence confirms this scenario for the first time in the most graphic way imaginable.

Study shows ancient Alaskans were freshwater fishers      (via sciencedaily.com)     Original source 

A scientific team has discovered the earliest-known evidence of freshwater fishing by ancient people in the Americas. The research offers a glimpse at how early humans used a changing landscape and could offer insight for modern people facing similar changes.

Hotter sand from microplastics could affect sea turtle development      (via sciencedaily.com)     Original source 

New research has found that extreme concentrations of microplastics could increase the temperature of beach sand enough to threaten the development of incubating sea turtles.

Scientists investigate the evolution of animal developmental mechanisms, show how some of Earth's earliest animals evolved      (via sciencedaily.com)     Original source 

Lacking bones, brains, and even a complete gut, the body plans of simple animals like sea anemones appear to have little in common with humans and their vertebrate kin. Nevertheless, new research shows that appearances can be deceiving, and that a common genetic toolkit can be deployed in different ways to drive embryological development to produce very different adult body plans. It is well established that sea anemones, corals, and their jellyfish relatives shared a common ancestor with humans that plied the Earth's ancient oceans over 600 million years ago. A new study from the Gibson Lab, published in Current Biology on June 13, 2023, illuminates the genetic basis for body plan development in the starlet sea anemone, Nematostella vectensis. This new knowledge paints a vivid picture of how some of the earliest animals on earth progressed from egg to embryo to adult.

Why certain fish are left off the hook      (via sciencedaily.com)     Original source 

A new study found that while a piece of legislation designed to foster the sustainability of marine fisheries is sometimes blamed for being too stringent -- leading to what some politicians call 'underfishing' -- the law is not constraining most fisheries, and there are various other reasons that lead to certain fish species being less fished.

When water temperatures change, the molecular motors of cephalopods do too      (via sciencedaily.com)     Original source 

Working with live squid hatchlings, scientists find the animals can tune their proteome on the fly in response to changes in ocean temperature via the unique process of RNA recoding. The findings inspire new questions about basic protein function.

Whales not to be counted on as 'climate savers'      (via sciencedaily.com)     Original source 

Do whales increase the removal of carbon from the atmosphere? Despite some hope that this would be the case, a new study has found the amount of potential carbon capture by whales is too little to meaningfully alter the course of climate change. The team found the amount potentially sequestered by the whales was too minimal to make significant impact on the trajectory of climate change.

Phenomenal phytoplankton: Scientists uncover cellular process behind oxygen production      (via sciencedaily.com)     Original source 

According to new research, the amount of oxygen in one of 10 breaths was made possible thanks to a newly identified cellular mechanism that promotes photosynthesis in marine phytoplankton. The new study identifies how a proton pumping enzyme (known as VHA) aids in global oxygen production and carbon fixation from phytoplankton.

Protecting large ocean areas doesn't curb fishing catches      (via sciencedaily.com)     Original source 

In the first-ever 'before and after' assessment of the impact of establishing Mexico's Revillagigedo National Park on the fishing industry, a team of US and Mexican researchers found that Mexico's industrial fishing sector did not incur economic losses five years after the park's creation despite a full ban in fishing activity within the MPA.

The clams that fell behind, and what they can tell us about evolution and extinction      (via sciencedaily.com)     Original source 

A new study examined how bivalves -- the group that includes clams, mussels, scallops, and oysters -- evolved among many others in the period of rapid evolution known as the Cambrian Explosion. The team found that though many other lineages burst into action and quickly evolved a wide variety of forms and functions, the bivalves lagged behind. The study has implications for how we understand evolution and the impact of extinctions.

Effective as a collective: Researchers investigate the swarming behavior of microrobots      (via sciencedaily.com)     Original source 

Miniaturization is progressing rapidly in just any field and the trend towards the creation of ever smaller units is also prevalent in the world of robot technology. In the future, minuscule robots used in medical and pharmaceutical applications might be able to transport medication to targeted sites in the body. Statistical physics can contribute to the foundations for the development of such technologies.
