POPSQuiet Explosion: Object Intermediate Between Normal Supernovae And Gamma-ray Bursts Found Stars that were at birth more massive than about 8 times the mass of our Sun end their relatively short life in a cosmic, cataclysmic firework lighting up the Universe. The outcome is the formation of the densest objects that exist, neutron stars and black holes. When exploding, some of the most massive stars emit a short cry of agony, in the form of a burst of very energetic light, X- or gamma-rays.

POPSWhat Do Your Genes Say About You? The Future of Personal Genomics The company 23andMe announced its DNA testing service last month in San Diego. You might think such a comprehensive analysis would costs thousands, but the process is actually relatively affordable. For less than $1,000 customers are able to learn virtually everything science currently knows about their biological code. For those wary of needles, you’ll be comforted to know that the DNA is retrieved conveniently and painlessly from a home mail-in saliva test kit.

POPSMore bad news for alarmists For example, the recent summary by Fred Singer and 22 expert contributors to “Nature, Not Human Activity, Rules the Climate” makes some extraordinary statements about computer models. (In addition to the many excellent contributors, this summary also contains 167 references to the scientific literature). This is important since computer models are being improperly, yet extensively, used by state legislatures as the basis of policies for greenhouse gas mitigation, rather than using actual climate data taken from the real world. These statements include: Computer models do not consider variations of irradiance and magnetic fields of the sun Computer models do not accurately model the role of clouds Computer models do not simulate a possible negative feedback from water vapor Computer models do not explain many features of the Earth’s observed climate. Computer models cannot produce reliable predictions of regional climate change.

POPSPsychology, Sociology most politically correct fields The first thing that Simmons does in the study with the database — which covers a range of disciplines and institution types — is to identify a politically correct cohort, reflecting largely common views on a set of issues that are seen as defining political correctness. He finds a set of issues that produce this cohort. The views are the belief that gender gaps in math and science fields are largely due to discrimination; support for affirmative action; and belief that discrimination is a key cause of racial inequities in American society. Generally, members of this cohort see race and gender as fundamental — and share that belief much more than beliefs about the curriculum or scholarship, such that the study says that “multiculturalism trumps postmodernism.” Via Tyler Cowen

POPSArtificial Intelligence under the spotlight at BA Festival ‘Computers are now one million times more powerful than when I started my research career – no field has come close to this rate of development,’ he says. ‘If transport had progressed at the same rate we would be flying from London to New York in less than a tenth of second.’

POPSAre We Living in a Giant Void? Their theory posits that if in fact Earth and our surrounding neighbors are in fact in an unusual or special region of space, ie, a void, then our perspective on the universe would be severely challenged
