Appeals Court Refuses to Halt Construction on Dakota Access Pipeline
In a setback for the Standing Rock Sioux Tribe and their supporters, on Sunday evening, one hour before the start of the second presidential debate, the DC Circuit Court of Appeals lifted an injunction that had stopped construction on the Dakota Access Pipeline, allowing work to resume.
The $3.7 billion, 1,170-mile pipeline would transport 470,000 barrels of crude oil across four states, which include sacred sites and burial grounds documented by the tribe.
"We are troubled by the court's decision, but as water protectors and land defenders, our resolve to stop this Bakken frack-oil pipeline will not be diminished," Tom Goldtooth, executive director of the Indigenous Environmental Network, said. "This fight is far from over."

Last month, after a federal judge rejected the tribe's challenge to halt construction on lands near their reservation, the Obama administration stepped in and revoked its authorization to construct the pipeline on federal land bordering or under Lake Oahu. The U.S. Army Corps of Engineers is conducting a review that it says will be completed within weeks.
In its order, the court noted, "But ours is not the final word. A necessary easement still awaits government approval—a decision corps' counsel predicts is likely weeks away; meanwhile, intervenor DAPL has rights of access to the limited portion of pipeline corridor not yet cleared—where the Tribe alleges additional historic sites are at risk."
"The Standing Rock Sioux Tribe is not backing down from this fight," Dave Archambault II, chairman of the Standing Rock Sioux Tribe, said on Facebook. "We are guided by prayer, and we will continue to fight for our people. We will not rest until our lands, people, waters and sacred places are permanently protected from this destructive pipeline."
While the court said the tribe hadn't met the strict requirements of Section 106 of the National Historic Preservation Act to force a halt to construction, it did express sympathy for the tribe saying, "We can only hope the spirit of Section 106 may yet prevail." Section 106 requires federal agencies to consult with tribes about any potential impact on their cultural and historic sites, and specifically directs agencies to "respect tribal sovereignty."
Archambault told NBC News, "It seems they are coming to the same conclusion as the federal government in acknowledging there is something wrong with the approvals for the pipeline. We see this as an encouraging sign."
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>
