Modern physics is not accidentally relativistic and quantum, or in other words, Einstein-relative as well as Everett-relative (Bell-violating Everett-relativity is the very core of quantum mechanics!). Modern physics becomes ever more relativistic still today, and description relativity has revolutionized fundamental physics (see string theory dualities, Maldacena conjecture, black hole complementarity/holography, and so on). Why? Because we must take the observer’s perspective, and this means the describer’s perspective, ever more into account.-->
It's a firmly established fact straight from Biology 101: Traits such as eye color and height are passed from one generation to the next through the parents' DNA.
But now, a new study in mice by researchers at Washington University School of Medicine in St. Louis has shown that the DNA of bacteria that live in the body can pass a trait to offspring in a way similar to the parents' own DNA. According to the authors, the discovery means scientists need to consider a significant new factor - the DNA of microbes passed from mother to child - in their efforts to understand how genes influence illness and health.
Attacks on institutions that keep records of global temperatures, such as NASA, the US National Oceanic and Atmospheric Administration, the UK Met Office, and Australia’s Bureau of Meteorology, continue to appear in the press.-->

(Inside Science) – Two bottles of whole milk sit side-by-side in a supermarket refrigerator. One costs $3.46 per gallon while the other costs $7.08 per gallon.
The difference? The second bottle of milk is labeled organic.
Reconstructions of human evolution are prone to simple, overly-tidy scenarios. Our ancestors, for example, stood on two legs to look over tall grass, or began to speak because, well, they finally had something to say. Like much of our understanding of early hominid behavior, the imagined diet of our ancestors has also been over-simplified.-->
Researchers at the Medical College of Wisconsin (MCW), in collaboration with other colleagues of the Genetic Epidemiology of Lung Cancer Consortium (GELCC), have identified a gene that is associated with lung cancer.
The findings are published in American Journal of Human Genetics. Through whole exome sequencing, researchers identified a link between a mutation in PARK2, a gene associated with early-onset Parkinson's disease, and familial lung cancer.
The researchers sequenced the exomes (protein coding region of the genome) of individuals from a family with multiple cases of lung cancer. They then studied the PARK2 gene in additional families affected by lung cancer.
For chimpanzees, just like humans, teasing, taunting and bullying are familiar parts of playground politics. An analysis of 12 years of observations of playground fights between young chimpanzees in East Africa finds that chimps with higher-ranked moms are more likely to win.
The results come from an analysis of daily field notes recorded from 2000 to 2011 at Gombe National Park in western Tanzania. Stored in the Jane Goodall Institute Research Center at Duke University and also at The George Washington University, the records are part of a larger database containing more than 50 years of data on over 300 wild chimpanzees, going all the way back to Jane Goodall's first observations from the early 1960s.

Latching onto the probiotics diet fad, several studies have claimed that the gut microbiome, the diverse array of bacteria that live in the stomach and intestines, may be to blame for obesity. But Katherine Pollard, PhD, a senior investigator at the Gladstone Institutes, says it is not that simple.
The Great Lakes have been invaded by more non-native species than any other freshwater ecosystem in the world. In spite of increasing efforts to stem the tide of invasion threats, the lakes remain vulnerable, according to scientists from McGill University and colleagues in Canada and the United States. If no new regulations are enforced, they predict new waves of invasions and identify some species that could invade the Lakes over the next 50 years.
