Facial Expressions Micro expressions are very brief facial expressions, lasting only a fraction of a second. They occur when a person either deliberately or unconsciously conceals a feeling. Seven emotions have universal signals: anger, fear, sadness, disgust, contempt, surprise and happiness. You can learn to spot them. History
Anne’s Astronomy News November 30, 2012 SNR 0509-67.5, a supernova remnant in the LMC Image Credit: X-ray: NASA/CXC/SAO/J.Hughes et al, Optical: NASA/ESA/Hubble Heritage Team (STScI/AURA) SNR 0509-67.5 (SNR 0509 for short) is the remnant of a supernova explosion in the Large Magellanic Cloud, located some 160,000 light-years away in the constellation of Dorado. It is about 23 light-years across and expanding at more than 5,000 kilometers a second, or more than 18 million kilometers an hour. This bubble is the visible remnant of a Type 1a supernova that occurred about 400 years ago in Earth’s time frame (what means that the light from the explosion reached us about 400 years ago), which was unusually bright and energetic.

Synopsis Born on December 27, 1822, in Dole, France, Louis Pasteur discovered that microbes were responsible for souring alcohol and came up with the process of pasteurization, where bacteria is destroyed by heating beverages and then allowing them to cool. His work in germ theory also led him and his team to create vaccinations for anthrax and rabies. Early Life
How Stephen Hawking, diagnosed with ALS decades ago, is still alive Stephen Hawking in 2007. (Bruno Vincent/Getty Images) On April 20, 2009, a moment arrived that doctors had foretold for decades. Stephen Hawking, a scientist who overcame debilitating disease to become the world’s most renowned living physicist, was on the cusp of death. The University of Cambridge released grim prognoses. Why Did Greenland's Vikings Vanish? On the grassy slope of a fjord near the southernmost tip of Greenland stand the ruins of a church built by Viking settlers more than a century before Columbus sailed to the Americas. The thick granite-block walls remain intact, as do the 20-foot-high gables. The wooden roof, rafters and doors collapsed and rotted away long ago. Now sheep come and go at will, munching wild thyme where devout Norse Christian converts once knelt in prayer.

Among them were a Russian team that recently came within 30 meters of drilling into Lake Vostok -- a subglacial lake some 4,000 meters below the surface of the ice -- and the crew of the IceCube Neutrino Observatory, who have been burying a massive array of detectors deep in the ice. (They placed their final detector in December.) Gathered here are recent images of Antarctica, its environment, and some of the scientific work taking place there. [47 photos]
Gregor Mendel View Biographies Related ToCategoriesDates Gregor Mendel, in full Gregor Johann Mendel, original name (until 1843) Johann Mendel (born July 22, 1822, Heinzendorf, Silesia, Austrian Empire [now Hynčice, Czech Republic]—died January 6, 1884, Brünn, Austria-Hungary [now Brno, Czech Republic]), botanist, teacher, and Augustinian prelate, the first to lay the mathematical foundation of the science of genetics, in what came to be called Mendelism. Education and early career Born to a family with limited means in German-speaking Silesia, Mendel was raised in a rural setting.
Jacques Rancière: Aesthetics is Politics Sophie Berrebi In the 2005 Venice Biennale, Kyrgyzstan, Uzbekistan and Kazakhstan were represented for the first time in a shared Central Asia pavilion that presented a curious and seductive group exhibition entitled ‘A Contemporary Archive’. Several videos and installations included in the show conveyed a strange feeling of déjà vu, by reworking avant-garde forms of the 1970s and 1980s – Abramovic and Ulay’s Light/Dark (1977), Kabakov’s domestic interiors of Soviet Russia – to make them espouse a search for political and ethnic identity initiated by these new post-soviet republics. The way these artistic forms travelled from the past to change meaning in the present raised the question of the displacement of ‘critical’ art in new contexts and beyond this, the exhibition begged the question of whether or not it was possible to perceive the art of these countries independently from their specific political context.
The Real Story of 'Hidden Figures' and NASA's Women Computers Katherine Johnson, the movie's protagonist, was something of a child prodigy. Hailing from the small West Virginian town of White Sulphur Springs, she graduated from high school at 14 and the historically black West Virginia State University at 18. In 1938, as a graduate student, she became one of three students—and the only woman—to desegregate West Virginia's state college. In 1953, Johnson was hired by NACA and, five years later, NACA became NASA thanks to the Space Act of 1958. The movie muddies the timeline a bit, but Johnson's first big NASA assignment was computing the trajectories for Alan Shepard's historic flight in 1961. Johnson and her team's job was to trace out in extreme detail Freedom 7's exact path from liftoff to splashdown.
Monster Black Hole Is the Largest and Brightest Ever Found Astronomers have discovered the largest and most luminous black hole ever seen — an ancient monster with a mass about 12 billion times that of the sun — that dates back to when the universe was less than 1 billion years old. It remains a mystery how black holes could have grown so huge in such a relatively brief time after the dawn of the universe, researchers say. Supermassive black holes are thought to lurk in the hearts of most, if not all, large galaxies.
