Shape and depth of ocean floor profoundly influence how carbon is stored there      (via sciencedaily.com)     Original source 

The movement of carbon between the atmosphere, oceans and continents -- or carbon cycle -- regulates Earth's climate, with the ocean playing a major role in carbon sequestration. A new study finds that the shape and depth of the ocean floor explain up to 50% of the changes in depth at which carbon has been sequestered there over the past 80 million years. While these changes have been previously attributed to other causes, the new finding could inform ongoing efforts to combat climate change through marine carbon sequestration.

The embryo assembles itself      (via sciencedaily.com)     Original source 

Biological processes depend on puzzle pieces coming together and interacting. Under specific conditions, these interactions can create something new without external input. This is called self-organization, as seen in a school of fish or a flock of birds. Interestingly, the mammalian embryo develops similarly. Scientists now introduce a mathematical framework that analyzes self-organization from a single cell to a multicellular organism.

Crucial shift in River Nile's evolution during ancient Egypt discovered      (via sciencedaily.com)     Original source 

Researchers have explored how the River Nile evolved over the past 11,500 years and how changes in its geography could have helped shape the fortunes of ancient Egyptian civilization. Research reveals a major shift in the Nile around four thousand years ago, after which the floodplain in the Nile Valley around Luxor greatly expanded.

Greenhouses cover more and more of Earth's surface      (via sciencedaily.com)     Original source 

Greenhouse cultivation is booming globally, especially in the Global South -- and across one country in particular. This is revealed in a new study that deploys detailed satellite imagery and AI to map greenhouses across the planet. According to the researchers, the development is a source of both promise and concern.

Fresh findings: Earliest evidence of life-bringing freshwater on Earth      (via sciencedaily.com)     Original source 

New research has found evidence that fresh water on Earth, which is essential for life, appeared about four billion years ago -- five hundred million years earlier than previously thought.

Researchers call for return of Sumas Lake following devastating 2021 floods      (via sciencedaily.com)     Original source 

A new proposal has emerged in response to the November 2021 floods that swept Sumas Prairie in the Fraser Valley, British Columbia, causing mass evacuations and millions in damages. Instead of rebuilding the dykes to manage water flows and prevent future floods, scientists, along with members of the Sumas First Nation and other research partners, suggest an alternative: let Sumas Lake, which was drained in the early 1920s and converted into the farmland known as Sumas Prairie, return to its natural state. This can be done by buying out properties on the lakebed -- a solution that is projected to cost around $1 billion, less than half of the estimated $2.4 billion cost of repairing the dykes and installing a new pump station.

Paving the way for hydrogen from algae enzymes      (via sciencedaily.com)     Original source 

Under certain conditions, some algae are able to produce hydrogen -- a much sought-after green energy source. Its production takes place in the unique catalytic center of the unicellular algae and is only possible if certain cofactors of the relevant proteins are present. Researchers have identified how such a cofactor, the so-called hydrogen cluster, is assembled. Specifically, they describe the previously unexplained role of the enzyme HydF, which is involved in the final steps of assembly.

Mussels downstream of wastewater treatment plant contain radium, study reports      (via sciencedaily.com)     Original source 

Burrowed into streambeds and rarely moving for their decades-long lifespans, freshwater mussels are biomonitors, meaning they indicate how clean their environment is, according to researchers. As the bivalves feed on organic matter and filter the water around them, their inner tissues and hard shells begin to reflect whatever is in their environment -- including radioactive particles.

Researchers discover 'trojan horse' virus hiding in human parasite      (via sciencedaily.com)     Original source 

An international team has found a new RNA virus that they believe is hitching a ride with a common human parasite. The virus is associated with severe inflammation in humans infected with the parasite Toxoplasma gondii, leading the team to hypothesize that it exacerbates toxoplasmosis disease.

Lighting up the brain: What happens when our 'serotonin center' is triggered?      (via sciencedaily.com)     Original source 

Scientists have studied the main source of serotonin in the brain -- the dorsal raphe nucleus (DRN). By studying how activating the brain's 'serotonin center' affects awake animals for the first time, they found that serotonin from the DRN activates brain areas that affect behavior and motivation. Results show that DRN serotonin stimulation causes activation of the cerebral cortex and the basal ganglia, brain areas involved in many cognitive functions.

Mediterranean diet tied to one-fifth lower risk of early death in women      (via sciencedaily.com)     Original source 

In a new study that followed more than 25,000 initially healthy U.S. women for up to 25 years, researchers found that participants who had greater Mediterranean diet intake had up to 23% lower risk of all-cause mortality, with benefits for both cancer mortality and cardiovascular mortality.

People are altering decomposition rates in waterways      (via sciencedaily.com)     Original source 

Humans may be accelerating the rate at which organic matter decomposes in rivers and streams on a global scale, according to a new study. That could pose a threat to biodiversity in waterways around the world and increase the amount of carbon in Earth's atmosphere, potentially exacerbating climate change. The study is the first to combine a global experiment and predictive modeling to illustrate how human impacts to waterways may contribute to the global climate crisis.

Historic iceberg surges offer insights on modern climate change      (via sciencedaily.com)     Original source 

A great armada entered the North Atlantic, launched from the cold shores of North America. But rather than ships off to war, this force was a fleet of icebergs. And the havoc it wrought was to the ocean current itself. The future of the Atlantic circulation will be determined by a tug-o-war between Greenland's decreasing ice flux and its increasing freshwater runoff.

New method makes hydrogen from solar power and agricultural waste      (via sciencedaily.com)     Original source 

Engineers have helped design a new method to make hydrogen gas from water using only solar power and agricultural waste such as manure or husks. The method reduces the energy needed to extract hydrogen from water by 600%, creating new opportunities for sustainable, climate-friendly chemical production.
