Is there a sense in which a gun, once put in hand, must be fired? If so, how deeply does this expectation, this foreshadowing of action, soak into its holder? How might the surrounding culture (hunting versus “tactical”) and type of gun shape these expectations? One holds a gun by its grip. Is there a…
NASA’s long-lived Mars rover Opportunity that beat newcomer sister probe Curiosity to an area containing water-formed clay minerals, has found that the spot may be far richer than scientists first realized. A new study looks at chemicals spotted by a Mars-orbiting spacecraft to conclude that Endeavour Crater, which Opportunity reached in August 2011 after a…
University of Toronto Faculty of Medicine researchers have uncovered a genetic basis for fundamental differences between humans and other vertebrates that could also help explain why humans are susceptible to diseases not found in other species. Scientists have wondered why vertebrate species, which look and behave very differently from one another, nevertheless share very similar…
An exploding meteor that blasted its fragments across California’s Gold Country in April has revealed rare evidence of its origin in a single family of asteroids hundreds of millions of miles from Earth, astronomers report. Seventy-seven bits of space debris collected around Sutter’s Mill in El Dorado County, where they fell on April 22, have…
Winter solstice is the longest night and shortest day of the year. A time of ending and new beginnings as now the days will slowly begin to lengthen again. For Pagans, Solstice is symbolically the night when the Sun Child is reborn out of the womb of Mother Night. For the Mayans, this year marks…
A number of the largest black holes in the universe may be even bigger than previously thought, researchers say. “Ultramassive black holes — that is, black holes with masses exceeding 10 billion solar masses — are probably not rare; several and even dozens of these colossal black holes may exist,” said Stanford astrophysicist Julie Hlavacek-Larrondo….
Coal took another serious hit Wednesday — in the heart of coal country. American Electric Power, or A.E.P., the nation’s biggest consumer of coal, announced that it would shut its coal-burning boilers at the Big Sandy electric power plant near Louisa, Ky., a 1,100-megawatt facility that since the early 1960s has been burning coal that…
A $45 million pot to fund innovative projects that aim to increase government transparency and accountability using web and mobile technology has been unveiled by the U.K., U.S. and Swedish governments. The U.S. Agency for International Development (USAID) launched the Making All Voices Count (MAVC) initiative in early December to support Internet-based technologies that increase…
A new map that divides the world’s vertebrates into 11 biogeographic realms is the biggest update to a 19th century version, and one of the most important maps for our understanding of global biodiversity. The map was published online in the journal Science. The original map was created by naturalist Alfred Russel Wallace in 1876. He divided the…
In a discovery that may prove important for cognitive science, our understanding of nature and applications for robot vision, researchers at the University of Adelaide have found evidence that the dragonfly is capable of higher-level thought processes when hunting its prey. The discovery, published online in the journal Current Biology, is the first evidence that…
