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
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.
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.
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.

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.
“You can’t leave it all to the markets.”
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.
The world is in the throes of an extinction crisis unlike any throughout paleoclimate history, aka: the Sixth Mass Extinction, keeping in mind that the normal “background rate” for extinction is 1-to-5 species gone per year. But, what if it is five (5) every 24 hours? Answer: It’s a lot more than that.
