  • Can a person's Facebook profile reveal what kind of employee he or she might be? The answer is yes, and with unnerving accuracy,
  • Other things a prospective employer might be able to glean from your Facebook profile is openness to new experiences (vacation pictures from a glacier off New Zealand), emotional stability (are your friends constantly offering you words of comfort?) and agreeableness (are you constantly arguing with "friends?").
  • series of two studies
  • ...16 more annotations...
  • six people with experience in human resources were asked to rate a sample of 500 people in terms of key personality traits using only the sample group's Facebook pages as a guideline.
  • rate members of the sample group on what is known as the "Big Five" personality traits
  • extroversion, conscientiousness, emotional stability, agreeableness and openness to new experiences
  • High scores
  • indication of future good job performance.
  • Members of the sample group were asked to give a self-evaluation and took an IQ test.
  • followed up with the employers of people in the sample group six months after their personality traits were rated, to ask questions about job performance.
  • raters were generally in agreement about the personality traits expressed in the sample group's Facebook page
  • ratings correlated strongly with self-rated personality traits
  • also found that the Facebook ratings were a more accurate way of predicting a person's job performance than an IQ test
  • employers need to tread carefully here
  • Facebook page can provide a lot of information that it would be illegal for an employer to ask of a candidate in a phone interview
  • gender, race, age and whether they have a disability
  • a 2011 study
  • found that 90 percent of recruiters and hiring managers look at an applicant's Facebook page whether they should or not.
  • one study should be used as a reason to start using Facebook in hiring.

Runaway Planets Tossed From Galaxy at Fraction of Speed of Light | Space.com - 1 views

  • Planets in tight orbits around stars that get ejected from our galaxy may actually themselves be tossed out of the Milky Way at blisteringly fast speeds of up to 30 million miles per hour, or a fraction of the speed of light, a new study finds.
  • would be some of the fastest objects in the galaxy, aside from photons
  • In terms of large, solid objects, they would be the fastest. It would take them 10 seconds or so to cross the diameter of the Earth
  • ...10 more annotations...
  • In 2005, astronomers found evidence of a runaway star that was flying out of the Milky Way galaxy at a speed of 1.5 million mph (2.4 million kph).
  • part of a double-star system that wandered too close to the supermassive black hole
  • In the seven years since, 16 of these hypervelocity stars have been found
  • typical runaway planet would likely dash outward at 7 to 10 million mph (11.3 to 16.1 million kph), but given the right circumstances, a small fraction could have their speeds boosted to up to 30 million mph (48.3 million kph).
  • hypervelocity planets will escape the Milky Way and travel through interstellar space
  • a civilization on such a planet, they would have a very exciting journe
  • Once the planet exits from the local group of galaxies, it will be accelerated away by cosmic expansion. So, within 10 billion years, it would go from the center of the galaxy to all the way to the edge of the observable universe
  • planet that tightly orbits a runaway star will cross in front and cause its brightness to dim slightly in what astronomers call a "transit
  • To hitch a ride on a hypervelocity star, a planet would have to be locked in a tight orbit, which ups the odds of witnessing a transit to around 50 percent
  • first time someone is talking about searching for planets around hypervelocity stars

  • For those inspired by Roger's look for the day, you can participate by adding a Johannes Kepler (the namesake of the mission) likeness to your personal photo and sharing with the NASA Kepler mission community on Facebook and Twitter.
  • identification of potentially habitable planets requires deep thought. To think deeply, we must dress as deep thinkers have dressed in the past. There is nothing that speaks of deep thought more plainly than a formal neck-ruff

Scientists Color Silk By Feeding Silkworms Fabric Dyes | Popular Science - 0 views

  • team fed ordinary silkworms mulberry leaves that had been sprayed with fabric dyes. Out of seven tested dyes, only one worked, producing a thread that reminded me of pink-dyed hair.
  • the worms themselves take on some color before they weave their silk cocoons. Their colorful diets did not affect their growth
  • coloring fabric normally uses enormous amounts of fresh water
  • ...7 more annotations...
  • The water gets contaminated with dangerous chemicals in the process, requiring costly treatment before factories can dump it back into waterways—or wreaking havoc when factory owners dodge cleanup rules
  • Scientists are just starting to study this idea, however, it remains to be seen if it's commercially viable
  • In this experiment, the Indian team tested seven azo dyes, which are cheap and popular in the industry
  • The scientists found different dyes moved through silkworms' bodies differently. Some never made it into the worms' silk at all
  • Others colored the worms and their cocoons, but the color molecules settled mostly in the sticky protein the worms add to their cocoons
  • That sticky stuff gets washed away before the silk is turned into fabric
  • Only one dye, named "direct acid fast red," showed up in the final, washed silk threads. By the time it made it there, it was a pleasant, light pink.

shared by Mars Base on 18 Jan 14 - No Cached
  • NASA invited the public to submit their names that will be engraved on a microchip aboard a spacecraft that will head to the 1,760-foot-wide asteroid.
  • The spacecraft will be sent to the asteroid where it will collect about two ounces of surface material and return with it to Earth in a sample-return capsule in 2023
  • submit their names online before September 30 at 'Message to Bennu.'
  • ...5 more annotations...
  • your name not just stays up there for 500 days but will remain in space even after the spacecraft returns the capsule to Earth.
  • Those who have submitted their names can download and print a certificate documenting their participation in the OSIRIS-REx mission
  • Participants who have registered their names and who 'follow' or 'like' the asteroid mission on Facebook and Twitter will get notifications on the status of their name in space from the time it is launched and until the samples are returned to Earth in 2013.
  • The aim of the OSIRIS-Rex mission is to address the basic questions on the composition of the early solar system.
  • Once the samples return to the Earth, the spacecraft will be placed into a long term solar orbit around the sun, along with the microchip on which the names are engraved.
