The Solar System Gets Bigger, Neptune's Moon's Mini-Moon, Weird Twins, A Tiny T-Rex and More!

In a mini-episode about the news Dave talks about the newest farthest object in the solar system, a chip off Neptune's moon Proteus, some bad climate news and a new carbon-capture device that might save us, a tiny predecessor of the t-rex, a rare case of semi-identical twins, and some more bad news for DNA evidence.

Climate rewind: Scientists turn carbon dioxide back into coal
New technique can efficiently convert CO2 from gas into solid particles of carbon
Scientists have harnessed liquid metals to turn carbon dioxide back into solid coal, in research that offers an alternative pathway for safely and permanently removing the greenhouse gas from our atmosphere. The new technique can convert carbon dioxide back into carbon at room temperature, a process that's efficient and scalable. A side benefit is that the carbon can hold electrical charge, becoming a supercapacitor, so it could potentially be used as a component in future vehicles.   (more...)

Earth may be 140 years away from reaching carbon levels not seen in 56 million years

Total human carbon dioxide emissions could match those of Earth's last major greenhouse warming event in fewer than five generations, new research finds. A new study finds humans are pumping carbon dioxide into the atmosphere at a rate nine to 10 times higher than the greenhouse gas was emitted during the Paleocene-Eocene Thermal Maximum (PETM), a global warming event that occurred roughly 56 million years ago.   (more...)
