Descent to a Comet



Yesterday, the first soft landing on a comet took place some 500 million kilometers from planet Earth as the Rosetta mission lander Philae settled on the nucleus of C67/P Churyumov-Gerasimenko. The landing site, dubbed Agilkia, is located near the center of this remarkable image snapped by Philae's ROLIS (ROsetta Lander Imaging System) camera. Taken from a distance of about 3 kilometers the image has a resolution of about 3 meters per pixel at the surface. After Philae's release from the orbiter, its seven-hour long descent was made without propulsion or guidance. Following its descent the lander is in place, though its anchoring harpoon system did not fire. For 2.5 days the lander is intended to conduct its main science mission returning extensive images and data. An extended surface mission may be possible if sunlight and dust conditions allow solar panels to recharge Philae's battery.

Beautiful online neuroscience learning


The Fundamentals of Neuroscience is a free online course from Harvard and it looks wonderful – thanks to them employing animators, digital artists and scientists to lift the course above the usual read and repeat learning.


The course is already underway but you can register and start learning until mid-December and you can watch any of the previews to get a feel for what’s being taught. You need to register to access the full content but there’s plenty of trailers online. Great stuff.

neveneke:



French doctors are puzzling over the case of 44-year-old civil servant who has led a quite normal life - but with an extraordinarily tiny brain .



In a case history published in Saturday’s Lancet, doctors led by Lionel Feuillet of the Hopital de la Timone in Marseille say the father-of-two was admitted to hospital after suffering mild weakness in his left leg.



Scans by computed tomography (CT) and magnetic resonance imaging (MRI) showed that the man’s cerebral cavities, called ventricles, had massively expanded.



"The brain itself, meaning the grey matter and white matter, was completely crushed against the sides of the skull,"


"The images were most unusual… the brain was virtually absent,"


Neuropsychological testing revealed the man had an IQ of 75, with a verbal IQ of 84 and performance IQ of 70. The bulk of people in society have a minimum IQ of 85, although the benchmark and the way it is measured are sometimes contested.



Despite this, “the man has been able to lead a life that can be considered normal,” said Feuillet. “Even if he has a slight intellectual handicap, this has not hampered his development or building social networks.”
