by Heather Callaghan,Have you ever overheard an intense or heart-wrenching discussion only to find out the talkers were actually hashing out the lives of fictional TV characters? Do you ever wonder why people are so easily beguiled into trusting the talking heads?It might not be such a mystery when you find out how easy it is for TV programming– the waves it emits, the storytelling – to override basic brain function and even damage your body.Reported earlier by [...]
Buck Rogers, Staff WriterHave you ever wondered what the world would be like if better and cleaner energy sources were widely available and affordable to all of earth’s people? If so, you’re not alone, as the quest for a better energy existence has been the focus of many ingenious inventors, scientists, experimenters and even corporate and government scientists for generations.We know it’s possible, but for some reason, though, society just can’t seem to get b [...]
Makia Freeman, ContributorGluten-free food is now very common and available, whether you are in a restaurant, cafe or grocery store. Although there are definitely people who suffer from celiac disease and other diseases triggered by gluten, the entire gluten-free movement has left many health experts and nutritionalists scratching their heads in bewilderment. Since when did large chunks of populations used to eating bread, pasta and other wheat products suddenly suffer from [...]
Terence Newton, Staff WriterIt has been over four years since the 9.0 magnitude Tōhoku earthquake and ensuing catastrophic tsunami leveled the Pacific coast of Japan, setting off a nuclear meltdown at the Fukushima Daichi power plant. Radiation has been pouring into the ocean, into the earth below, and into the air for over 1500 days now and there is still zero sense of urgency on the part of the government and world leaders to seriously address this blooming catastrop [...]
Excerpt from The Science of The Dogon, by Laird ScrantonThe information presented in the preceding chapters demonstrates a direct relationship between the symbols and themes of the Dogon creation story and known scientific facts relating to the formation of the universe, matter, and biological reproduction. This relationship is a broad and specific one that is couched in clear definitions and supported by priestly interpretations and cosmological drawings. The parallels between Dogon myth [...]
May 9, 2015 / Greg Giles / Comments Off on Astronomers Giddy Over What They Call A Cosmic ‘Dinosaur Egg’ About To Hatch
The Antennae galaxies, shown in visible light in a Hubble image (upper image), were studied with ALMA, revealing extensive clouds of molecular gas (center right image). One cloud (bottom image) is incredibly dense and massive, yet apparently star free, suggesting it is the first example of a prenatal globular cluster ever identified.
Excerpt from huffingtonpost.com A dense cloud of gas 50 million light-years away has astronomers buzzing, and they're using all sorts of strange metaphors to get the rest of us to pay attention.
They've discovered what they think may be a globular cluster -- a big ball of up to one million stars -- on the verge of being born.
“This remarkable object looks like it was plucked straight out of the very early universe," Dr. Kelsey Johnson, an astronomer at the University of Virginia in Charlottesville and lead author on a paper about the research, said in a written statement. "To discover something that has all the characteristics of a globular cluster, yet has not begun making stars, is like finding a dinosaur egg that’s about to hatch.”

Johnson and her colleagues spotted the bizarre object, which they call the "Firecracker," using the Atacama Large Millimeter/submillimeter Array (ALMA) in the Atacama desert in Chile. It's located inside a pair of interacting galaxies known to scientists as NGC 4038/NGC 4039, or The Antennae Galaxies.
The Firecracker has a mass that's 50 times that of our sun, and is under an enormous amount of pressure -- roughly 10,000 times greater than the average pressure in interstellar space. According to the researchers, this makes it a good candidate for collapsing into a globular cluster within the next million years.
What do other scientists make of the discovery? Dr. Alison Peck, ALMA scientist at the National Radio Astronomy Observatory, who was not involved in the new research, called it "important" and said she was "really excited to hear about these results." She told The Huffington Post in an email:
"One of the things that we all yearn to understand is how our surroundings formed, how our galaxy and our solar system came to be. To do this, since we can’t actually watch things change over time, (it just takes too long), we need to find similar objects at different stages of development and compare them. What Dr. Johnson’s team have found here is an analog of an object that we look for in the very early universe, but they’ve found it so close by that we’ll be able to make extremely detailed observations and find out much more about the physical conditions in this exciting region."
The research is set to be published in the Astrophysical Journal.

Leapfrogging backward in time to when the universe was apparently feeling its oats, a group of astronomers reported Tuesday that they had measured a bona fide distance to one of the farthest and thus earliest galaxies known.
The galaxy, more than a few billion light-years on the other side of the northern constellation Boötes, is one of the most massive and brightest in the early universe and goes by the name of EGS-zs8-1.
It flowered into stardom only 670 million years after the Big Bang.
The light from that galaxy has taken 13 billion years to reach telescopes on Earth. By now, however, since the universe has continued to expand during that time, the galaxy is about 30 billion light-years away, according to standard cosmological calculations.
The new measurements allow astronomers to see the galaxy in its infancy. Despite its relative youth, however, it is already about one-sixth as massive as the Milky Way, which is 10 billion years old. And it is getting bigger, making stars 80 times faster than the Milky Way is making them today. The discovery was reported in The Astrophysical Journal by Pascal Oesch of Yale University and his colleagues.
By the rules of the expanding universe, the farther away a galaxy is, the faster it is retreating from us, measured by the “redshift” of its light being broadened to longer wavelengths, the way an ambulance siren seems to lower its pitch as it goes by.
In the past few years, as astronomers have raced one another into the past with instruments like the Hubble Space Telescope, galaxies have been found that appear even more distant. Those measurements, however, were estimates based on the colors of the objects — so-called photometric redshifts.
The new galaxy stuck out in a survey of distant galaxies by the Hubble and Spitzer space telescopes known as Candels, for Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey. Its redshift was precisely measured with a powerful spectrograph known as Mosfire — Multi-Object Spectrometer for Infrared Exploration — on Keck 1, one of a pair of 10-meter-diameter telescopes on Mauna Kea in Hawaii. That makes it the highest redshift confirmed in this way, said Garth Illingworth, of the University of California, Santa Cruz, one of the astronomers in the study.
How galaxies were able to form and grow so rapidly after the lights came on in the universe is a mystery that will be addressed by a coming generation of instruments like the James Webb Space Telescope and the Thirty Meter Telescope, a goliath planned for Mauna Kea, already home to a dozen telescopes.
Recently, however, construction of the Thirty Meter Telescope, a $1.4 billion project, has been halted by protests by Hawaii residents who feel their mountain has been abused. An echo of that controversy appears in the new paper, in which Dr. Oesch and his colleagues write: “The authors wish to recognize and acknowledge the very significant cultural role and reverence that the summit of Mauna Kea has always had within the indigenous Hawaiian community. We are most fortunate to have the opportunity to conduct observations from this mountain.”
