Over 100 million years ago, late Mesozoic forests were chock full of a diverse group of plants of the class Equisetopsida, though only one genus, Equisetum, commonly called scouring rush or horsetail, still exists today.
It is unclear about the evolutionary beginnings of the genus Equisetum - molecular dating places the divergence of the 15 extant species of the genus around 65 million years ago but the fossil record had it earlier than that, around 136 million years ago.
Here, I present for you a snippet from the Western Electric document
Introduction to Project Mercury and Site Handbook on one of the most important aspects of a space program that barely existed; ground control and monitoring. You know, the part where they actually know what the astronaut and his capsule are doing and decide whether or to send him into space and bring him back down, a wholly unnatural act.
a. Direct the entire flight in respect to the mission;
b. Monitor the flight in respect to aeromedical and capsule systems;
c. Keep the astronaut and range stations informed of mission progress;
A community survey in England identified people with
autism or asperger's syndrome and found none of them knew they have it. And autism turned out to be more prevalent in males with lower education and in government housing.Is autism causing people to have lower education and jobs or has the umbrella gotten so large it has become a blanket diagnosis for everyone not successful?
The results from the first ever general population survey of autism in adulthood. They are based on a two phase epidemiological survey in England (7,461 screening interviews; 618 diagnostic) carried out in 2007.
The findings are in the Archives of General Psychiatry.
In my American Literature course this semester, I worked to weave Joseph Campbell’s vision of the purpose of mythology throughout the pieces we read, to get students to consider the role that literature, in its many mediums, plays in providing the bedrock on which we live our lives and derive meaning. In a world in which religion no longer dominates our culture and for many people no longer lives and breathes, providing the answers for all life’s mysteries and meanings, the stories we listen to, watch, or read often become the essential framework on which we hang our own life narratives. Even when we maintain a religious belief structure, it is often not the dominant feature of our lives, and the stories we enjoy are often much more immediate and relevant.
My Project Calliope satellite will be launched on an Interorbital Systems (IOS) rocket-- but IOS hasn't yet launched into orbit. Where are they, how close are we to launch, and what's the risk?
Ad: Support Calliope-- limited edition flight gear available until May 21 at kickstarter!
Mike Rangers has a post called "14 signs that the collapse of our modern world has already begun." If it weren't so scary to think of how easily people can be conned, it would almost be funny that he's so wide-ranging in his all-knowingness. That's the beauty of instant expertise, isn't it? Just google it, or even better, just pronounce it on your blog with complete and utter confidence in your competence, regardless of your knowledge-base. After all, isn't that why those heavy hitters at AoA believe they understand complex science that most experts, in order to be experts, spend a decade or more in intense, competitive study, with even more intense testing to prove competency? If you write it down, it makes it real, and it makes it right.
What draws people to communal rituals has long been a topic of interest to sociologists and anthropologists. What draws people to a communal ritual like walking on hot coals is a topic of interest for, well, everyone. We all are fascinated by it but few want to do it, yet it has been going on (that we know of) since 1200 B.C.
DUIVEN, Netherlands, May 3, 2011 /PRNewswire/ -- The fourth batch of generic EU health claim opinions delivered by the European Food Safety Authority [EFSA] in April saw the previous trend of negative opinions continue: 20% successful, 80% unsuccessful. Companies that have upheld health claims have been quick to promote this through marketing use of words like "proven" and "scientific support."
This trend comes as manufacturers opt for softer or passive claims [e.g. "low and light"], as claims uncertainty continues.
