Bits of Mystery DNA, Far From ‘Junk,’ Play Crucial Role“As scientists delved into the ‘junk’ — parts of the DNA that are not actual genes containing instructions for proteins — they discovered a complex system that controls genes. At least 80 percent of this DNA is active and needed. The result of the work is an annotated road map of much of this DNA, noting what it is doing and how. It includes the system of switches that, acting like dimmer switches for lights, control which genes are used in a cell and when they are used, and determine, for instance, whether a cell becomes a liver cell or a neuron.”

New Research Suggests Bacteria Are Social Microorganisms“The research shows that a few individuals in groups of closely related bacteria have the ability to produce chemical compounds that kill or slow the growth of other populations of bacteria in the environment, but not harm their own.” – cooooooool!

Further Testing the Pioneer Hypothesis: Canada and Russia – from jayman.

Racial and ethnic diversity spreads across the country“Another significant finding is the decline in white-dominant places, where whites make up 90 percent or more of the population. Three decades ago these places represented two-thirds of the total. Today, they are down to only one-third of the total. In their stead are a growing number of communities where minorities are a significant share of the population and often where no group is a majority.” – see also nowhere to run.

Finnish ancestors’ diet explains many modern ailments – finnish cannibals!! also: “The late arrival of agriculture in Finland is still reflected in the Finnish people. According to Markku Niskanen a researcher into archaeology at the University of Oulu, the Finnish genotype is still not adapted well to the food that was introduced through agriculture, to say nothing of industrially produced nutrition. Niskanen believes that a possible reason why we have more adult-onset diabetes than other Europeans is that we are not accustomed to eating large amounts of grain.”

Social psychologists espouse tolerance and diversity — do they walk the walk? – see also Survey finds blatant bias and discrimination against conservatives in academia.

Redebunking Ron – chuck has “marshaled evidence from no less than 14 nationally representative samples (PISA 2009, PISA 2006, TIMSS 2007, PIRLS 2006, PIRLS 2001, ADD Health, GSS, NLSY 79, NLSY 97, CNLSY, NAEP Main, NAEP Long term, High School Transcript Study, and NELS) and demonstrated beyond a doubt that the claimed Ron effect was a mirage.”

bonus: Species multiply as Earth heats up“[E]ras of warming were accompanied by increases in biodiversity.” – previously evolution likes it hot.

bonus bonus: Evolution could explain the placebo effect“The model revealed that, in challenging environments, animals lived longer and sired more offspring if they endured infections without mounting an immune response. In more favourable environments, it was best for animals to mount an immune response and return to health as quickly as possible.”

bonus bonus bonus: The birdy smell of a compatible partner“New evidence shows that birds may choose their mate with the help of smell. They prefer a dissimilar mate because this gives their young a more efficient immune system.”

bonus bonus bonus bonus: Ancient, bottom-dwelling critter proves: Newer isn’t always better“Tiny, humble rhabdopleurids have lived on the ocean floor for some 500 million years, outlasting more elaborate descendants”
