11:50 PM | Emergencia ambiental en el río Pilcomayo
(English intro to Spanish lang post) On July 10th a dam bursted in a Bolivian mining town, spilling 30.000 cubic meters of polluted water into the Pilcomayo River. The mine extracts lead, silver and zinc, but the spill was abundant in several heavy metals. The Pilcomayo River runs through Bolivia to Argentina and Paraguay. There was an extensive and constant reporting in Bolivia from the beginning. Some stories alerted that the water could cause cancers, mental problems, birth defects, and […]

11:50 PM | Are these science writers and publications facing death threats for covering GMOs?
An anti-GMO activist has compared some science journalists and publications to the Nazis, saying they are "Monsanto collaborators who have signed on to accelerate heinous crimes being committed against humanity under the false promise of 'feeding the world' with toxic GMOs." In the post on his Natural News blog, Mike Adams also writes that " it is the moral right -- and even the obligation -- of human beings everywhere to actively plan and carry out the killing of those engaged in heinous […]

11:38 PM | Geo 730: July 24, Day 570: Stilbite Closeup
A closer view of yesterday's vesicular basalt. This shot is close enough that in crops of the full-size image, one can make out the individual blades. Compare the shape of the circled bits below to the diagrams and photos at this site. I will say, I take issue with their claim that "single individual crystals are very uncommon." Larger crystals that are not in clusters are not common, but smaller crystals, easily identified with the naked eye or with a hand lens, are pretty common, in my […]

11:06 PM | An Asteroid Occultation
Last Sunday, 20 July 2014, a small group of amateur astronomers sat in wait around a collection of small, jury-rigged telescopes, monitoring a faint nameless star in the constellation Virgo.  At about 7:18pm, with no drama or prelude, it winked out.  Eleven seconds later, it reappeared, shining steadily and dimly as before.  And yet only a handful of people could have seen this - observers anywhere else on Earth would have seen nothing out of the ordinary.   So what happened […]

10:49 PM | Where does the 10% myth come from?
No one knows exactly.  A nice summary of what we do know is provided in a recent WIRED piece here. William James was thought to play a role, based on a quote from Dale Carnegie's book, How to win friends and influence people, but this may have been a misquote.  Kolb and Wishaw's classic text, Fundamentals of Human Neuropsychology suggests Flourens work in the early 1800s as a likely empirical foundation for the myth.  Flourens of course is famous for his empirical attack on […]

9:23 PM | Das soziale Leben der Tyrannenechsen
Über die Probleme, das Verhalten und die Lebensweise ausgestorbener Tiere wie zum Beispiel der Dinosaurier zu erforschen, hatte ich ja schon geschrieben. Denn schließlich kann man da ja nicht einfach wie bei heute lebenden Tieren mit der Kamera und Notizbuch losziehen. Im Fall des allseits beliebten Tyrannosaurus rex führt das unter anderem zu der Debatte, ob er ein aktiver Jäger war oder ein reiner Aasfresser. Das ist alleine aus dem Skelett schwer zu entscheiden, denn das […]

9:02 PM | Game of Drones
Illustrations by Studio MUTI Most pilots enjoy keeping their drones airborne. Marque Cornblatt, who studied digital art before turning to robotics, has different pleasure centers in his brain. “Crash your drone,” he says. “Get your hands dirty fixing that thing. Come up with solutions to keep it flying.” This crash-and-rebuild philosophy came out of unmanned aerial vehicle (UAV) battles between Cornblatt and his friends. The duels were so much fun that they launched a […]
