Good morning! While hunting Easter eggs this morning the crew of the Space Station found a big one, full of goodies.

The Elements According to Relative Abundance
Roughly, the size of an element’s own niche is proportioned to its abundance on Earth’s surface, and in addition, certain chemical similarities.
New research shows that Twitter use can damage users’ romantic relationships.
Russell Clayton, a doctoral student at the University of Missouri School, found that active Twitter users are far more likely to experience Twitter–related conflict with their romantic partners.

When light travels through areas of different air density, it bends. You’ve probably noticed the way distant pavement seems to shimmer on a hot day, or the way stars appear to twinkle. You’re seeing light that has been distorted as it passes through varying air densities, which are in turn created by varying temperatures and pressures.
Schlieren Flow Visualization can be used to visually capture these changes in density: the rising heat from a candle, the turbulence around an airplane wing, the plume of a sneeze … even sound. Special thanks to Mike Hargather, a professor of mechanical engineering at New Mexico Tech, who kindly provided a lot of these videos.
Want to know which elementary particle best describes you? Well this interactive quiz by the DESY research centre and Universum Bremen will show you based on how you see yourself.
* My top 3 particles were the gluon, tau neutrino, and up quark.
The stress of growing up in a poor and unstable household affects children as young as 9 years old on a genetic level, shortening a portion of their chromosomes that scientists say is a key indicator of aging and illness, according to a study released Monday. The researchers say their findings are the first that document this type of genetic change among minority children, and make a strong case for the importance of early-childhood intervention in vulnerable communities.
Researchers examined the DNA of a small group of 9-year-old African-American boys who had experienced chronic stress as a result of growing up in families with poor socioeconomic status. They found that the boys’ telomeres were shorter than those of boys the same age and ethnicity who came from advantaged families.
A technical glitch causes the Hubble Space Telescope, which ordinarily captures magnificently crisp scientific imagery of the cosmos, to lose balance and create this inadvertent piece of modern art.
It is suspected that in this case, Hubble had locked onto a bad guide star, potentially a double star or binary. This caused an error in the tracking system, resulting in this remarkable picture of brightly colored stellar streaks. The prominent red streaks are from stars in the globular cluster NGC 288.
Green Apple Day of Service (GADoS), through the US Green Building Council (USGBC) Center for Green Schools,
provides an opportunity to transform schools into healthy, safe, and productive learning environments through
local service projects. The GADoS initiative is a great way to involve student groups, parent volunteers, and
local community organizations to make your school building or grounds greener and healthier.
Limerick poet Mick Twister rhymes yesterday’s news that physicists had observed gravitational waves, strong proof that cosmic inflation occurred in the earliest moments of our universe. (via jtotheizzoe)

This is what almost four billion years of human evolution looks like when it’s condensed down to ten seconds, thanks to the fine folks behind the original Cosmos.
From self-replicating bags of chemistry to billions of bacteria to crude multicellular blobs to tiny swimming monsters to clumsily creeping fish to fuzzy proto-mammals to weird, naked, two-legged apes … every cosmic blink holds a beautiful story.
If you’d like to retrace your steps along the path of time that ends with you, I recommend this awesome Wikipedia page.
The college majors that tend to lead to the most profitable professions are also the stingiest about awarding A’s. Science departments grade, on a four-point scale, an average of 0.4 points lower than humanities departments, according to a 2010 analysis of national grading data by Stuart Rojstaczer and Christopher Healy. And two new research studies suggest that women might be abandoning these lucrative disciplines precisely because they’re terrified of getting B’s.
New research shows that the part of the brain called the hippocampus stores memories by their ‘temporal context’ — what happened before and what came after.
“We need to remember not just what happened, but when,” said Liang-Tien (Frank) Hsieh, a graduate student at the University of California, Davis, Center for Neuroscience and first author on the study.
