Coal Ash Continues to Spill Into River, Where Is Duke Energy?
Waterkeeper Alliance and Sound Rivers have discovered a large coal ash spill into the Neuse River from the Duke Energy H.F. Lee facility, 10 miles upstream of Goldsboro, North Carolina. A substantial but undetermined amount of coal ash was found floating on the surface of the river in a layer over one inch thick. See the video below:
The spill came from at least one of three inactive coal ash ponds containing more than 1 million tons of exposed coal ash. The ponds had been submerged by Hurricane Matthew flood waters for more than seven days until flood waters receded over the weekend. Fly ash coated tree branches as much as seven feet above the river surface, indicating the spill began no later than last Tuesday, when the water level reached a record flood stage.

Independent microscopic analysis confirmed the white material is fly ash particles known as cenospheres, a waste product of coal combustion.
Upper Neuse Riverkeeper Matthew Starr, said:
"This spill is easily visible to anyone in a boat. The area looks like a winter wonderland of toxic coal ash as it has coated the water and trees. It is hard for me to understand how both Duke Energy and state regulators failed to notice such a large area of coal ash contaminating the Neuse River when they claim to have inspected these very ash ponds on Saturday."
On Oct. 15, Duke Energy issued a press release stating:
"Site inspections at the H.F. Lee Power Plant in Goldsboro, N.C., today confirm there was only very minor erosion of material from an inactive coal ash basin on the site.
The majority of that material, which includes coal ash, remained very close to the inactive basin, on the berm or a few feet away on the basin roadway. The state team that inspected the facility determined that the amount of material that was displaced would not even fill the bed of an average pickup truck."
"When a raging river floods over 1 million tons of coal ash, you're obviously going to get more than a pickup truck's worth of ash polluting the river," said Waterkeeper Alliance staff attorney Pete Harrison.
"It was very troubling to discover such a large amount of ash in the river, especially knowing that untold amounts of ash have been washing out of these ponds for more than a week now. It's baffling how Duke Energy could be so oblivious to such an obvious spill and how state regulators continue to look the other way when it comes to Duke's coal ash problems."

Four of five retired coal ash ponds at the H.F. Lee plant near Goldsboro, North Carolina were inundated for at least 7 days. The submerged ponds contain more than one million tons of coal ash, spread in a layer between four and ten feet thick across an area the size of 130 football fields. In a 2015 site assessment, Duke Energy reported high levels of toxic heavy metals in the flooded ponds, including arsenic, antimony and thallium.

Last week at the H.F. Lee facility, Duke Energy failed to identify a breach in a cooling pond dam the size of a school bus for as much as 24 hours before a local news helicopter spotted the collapsed dam and reported it to officials.
Sweden's reindeer have a problem. In winter, they feed on lichens buried beneath the snow. But the climate crisis is making this difficult. Warmer temperatures mean moisture sometimes falls as rain instead of snow. When the air refreezes, a layer of ice forms between the reindeer and their meal, forcing them to wander further in search of ideal conditions. And sometimes, this means crossing busy roads.

A chance discovery of a beautifully preserved fossil in the desert landscape of Morocco has solved one of the great mysteries of biology and paleontology: how starfish evolved their arms.
The Pompeii of palaeontology. Aaron Hunter, Author provided<h2></h2><p>Although starfish might appear very robust animals, they are typically made up of lots of hard parts attached by ligaments and soft tissue which, upon death, quickly degrade. This means we rely on places like the Fezouata formations to provide snapshots of their evolution.</p><p>The starfish fossil record is patchy, especially at the critical time when many of these animal groups first appeared. Sorting out how each of the various types of ancient starfish relate to each other is like putting a puzzle together when many of the parts are missing.</p><h2>The Oldest Starfish</h2><p><em><a href="https://www.biorxiv.org/content/10.1101/216101v1.full.pdf" target="_blank" rel="noopener noreferrer">Cantabrigiaster</a></em> is the most primitive starfish-like animal to be discovered in the fossil record. It was discovered in 2003, but it has taken over 17 years to work out its true significance.</p><p>What makes <em>Cantabrigiaster</em> unique is that it lacks almost all the characteristics we find in brittle stars and starfish.</p><p>Starfish and brittle stars belong to the family Asterozoa. Their ancestors, the Somasteroids were especially fragile - before <em>Cantabrigiaster</em> we only had a handful of specimens. The celebrated Moroccan paleontologist Mohamed <a href="https://doi.org/10.1016/j.palaeo.2016.06.041" target="_blank" rel="noopener noreferrer">Ben Moula</a> and his local team was instrumental in discovering <a href="https://www.sciencedirect.com/science/article/abs/pii/S0031018216302334?via%3Dihub" target="_blank" rel="noopener noreferrer">these amazing fossils</a> near the town of Zagora, in Morocco.</p><h2>The Breakthrough</h2><p>Our breakthrough moment came when I compared the arms of <em>Cantabrigiaster</em> with those of modern sea lilles, filter feeders with long feathery arms that tend to be attached to the sea floor by a stem or stalk.</p><p>The striking similarity between these modern filter feeders and the ancient starfish led our team from the University of Cambridge and Harvard University to create a new analysis. We applied a biological model to the features of all the current early Asterozoa fossils in existence, along with a sample of their closest relatives.</p>
Cantabrigiaster is the most primitive starfish-like animal to be discovered in the fossil record. Aaron Hunter, Author provided<p>Our results demonstrate <em>Cantabrigiaster</em> is the most primitive of all the Asterozoa, and most likely evolved from ancient animals called crinoids that lived 250 million years before dinosaurs. The five arms of starfish are a relic left over from these ancestors. In the case of <em>Cantabrigiaster</em>, and its starfish descendants, it evolved by flipping upside-down so its arms are face down on the sediment to feed.</p><p>Although we sampled a relatively small numbers of those ancestors, one of the unexpected outcomes was it provided an idea of how they could be related to each other. Paleontologists studying echinoderms are often lost in detail as all the different groups are so radically different from each other, so it is hard to tell which evolved first.</p>
