The demonstration began on the afternoon of May 21, 1946, at a secret laboratory tucked into a canyon some three miles from Los Alamos, New Mexico, the birthplace of the atom bomb. Louis Slotin, a Canadian physicist, was showing his colleagues how to bring the exposed core of a nuclear weapon nearly to the point of criticality, a tricky operation known as “tickling the dragon’s tail.” - The Demon Core and the Strange Death of Louis Slotin
By comparison to what it could have been, it’s a miracle. By comparison to what it should have been, it’s a disaster. - A historic deal has been struck in Paris to reduce carbon emissions and reduce global warming, with a ceiling of 2 degrees centigrade and a goal of 1.5C. 2015 has been the hottest year on record.

In the deep sea, low oxygen levels, scarce sunlight, and freezing water limit the rate at which items decompose: Something that might survive a few years on land could exist for decades underwater. - ROVs photograph trash on the ocean floor.
Is Science Fiction promoting pseuodoscience? Is it not really better than fantasy? Is it exhausted and dying, per Paul Kincaid (part 1, part 2), a sort of genre-writing version of completing a list of The Nine Billion Names of God?

In secrecy and silence they toiled at their Promethean task. They sought the ultimate weapon, one of such great power as to end not just their war, but all war. They hoped their work would salvage the future. They feared it could end everything. - Prometheus in the desert: from atom bombs to radio astronomy, New Mexico's scientific legacy

Sea urchins do not have eyes, yet appear to be able to see where they are going. One posible answer: they may use the entire surface of their bodies as a compound eye.
"Heads were skinned and muscles removed from the brain case in order to remove the skullcap. Incisions and scrapes on jaws indicate that tongues were cut out." "Scrape marks inside the broken ends of limb bones indicate that marrow was removed." "Whatever actually happened at Herxheim, facial bones were smashed beyond recognition." - Neolithic mass canibalism in southern Germany.
