UK Parliament Endorses Jeremy Corbyn’s Call for a Climate Emergency Declaration

Corbyn: “Are we content to hand down a broken planet to our children? That is the question members must ask themselves today. We have the chance to act before it’s too late. It’s a chance that won’t be available to succeeding generations. It is our historic duty to take it.” We publish Corbyn’s full speech calling for the declaration

Running may have made dinosaurs’ wings flap before they evolved to fly: New evidence suggests that passive wing flapping may have arisen earlier than gliding flight — ScienceDaily

Before they evolved the ability to fly, two-legged dinosaurs may have begun to flap their wings as a passive effect of running along the ground.

Rob Sheldon: Here’s why physicists are surprised by the universe’s increased expansion rate | Uncommon Descent

The two methods differ in that one is “direct” and the other “indirect”. Clearly one or both of them is making a mistake. Since it is hard to find (and people have looked) a reason why the direct method is failing, the feeling is that the indirect method must have a mistake in its model.

First hominins on the Tibetan Plateau were Denisovans: Denisovan mandible likely represents the earliest hominin fossil on the Tibetan Plateau — ScienceDaily

So far Denisovans were only known from a small collection of fossil fragments from Denisova Cave in Siberia. A research team now describes a 160,000-year-old hominin mandible from Xiahe in China. Using ancient protein analysis the researchers found that the mandible’s owner belonged to a population that was closely related to the Denisovans from Siberia. This population occupied the Tibetan Plateau in the Middle Pleistocene and was adapted to this low-oxygen environment long before Homo sapiens arrived in the region.

A first in medical robotics: Autonomous navigation inside the body: Robotic catheter, using a novel sensor informed by AI and image processing, makes its own way to a leaky heart valve — ScienceDaily

Bioengineers report the first demonstration of a robot able to navigate autonomously inside the body. In an animal model of cardiac valve repair, the team programmed a robotic catheter to find its way along the walls of a beating, blood-filled heart to a leaky valve — without a surgeon’s guidance.

Narwhals have endured a million years with low genetic diversity, and they’re thriving — ScienceDaily

Researchers have sequenced the genome of a narwhal, the Arctic whale famous for the horn-like tusk protruding from its forehead. Their work finds that compared to other Arctic marine mammals, narwhals have low genetic diversity, which typically indicates a species is struggling. However, narwhal populations number in the hundreds of thousands — but researchers warn they are still vulnerable to climate change and human activities in the Arctic.

Rapid permafrost thaw unrecognized threat to landscape, global warming researcher warns — ScienceDaily

Researchers have assessed abrupt thaw studies across the permafrost zone to estimate the overall effect. They found carbon emissions have the potential to double the climate feedback associated with permafrost thawing because abrupt thaw releases more methane. It will also have drastic effects on landscape, from altering traditional travel and hunting patterns in the North, to causing costly infrastructure damage to roads and rail lines.
