“Dark Heart of the Human Genome” –Surprising Neanderthal Influence

 

Neanderthal vs Human

 

“It’s the heart of darkness of the genome, we warn students not to go there,” said Charles Langley, professor of evolution and ecology at University of California, Davis. Geneticists exploring the dark heart of the human genome have discovered big chunks of Neanderthal and other ancient DNA. The results open new ways to study both how chromosomes behave during cell division and how they have changed during human evolution.

Pristine Apollo Samples –“Secrets that Scientists are Only Beginning to Uncover”

Apollo Mission

 

When Apollo lunar samples were brought back, the NASA curators had the foresight to say, “in this moment we don’t have all the methods to answer all the questions these samples could help us answer’ and so they locked some away for future study,” says Jessica Barnes, an incoming assistant professor in the UA’s Lunar and Planetary Laboratory, recently selected by NASA to receive access to preciously unopened moon rock samples.

Dark Matter –“A Strange Quantum Superfluid That Flows Without Entropy”

Galaxy Protocluster

 

“A superfluid is a very interesting kind of fluid,” says physicist Justin Khoury, a professor at the University of Pennsylvania, who focuses on the interface of particle physics and cosmology. “Most substances we find in the laboratory form a solid when cooled to a low enough temperature. But a certain set of substances, such as liquid helium, effectively remain a liquid all the way to absolute zero temperature.

“Two More” –Earth-like Planets Found in Our Milky Way Backyard

Red Dwarf Planets

 

“We have been observing this star for three years to look for periodic variations in its velocity,” explains Mathias Zechmeister, a researcher at the University of Göttingen. The observations showed that two planets are orbiting it, both of them similar to the planets in the inner part of the Solar System. They are just a little bigger than the Earth and are situated in the “inhabitable zone” where water can exist as a liquid.

From the X Files –“Project Mogul UFO Conspiracy & Nuclear War”

 

Nuclear Bomb Cloud

 

The 1947 crash in the New Mexico desert that become legendary among UFO fans and conspiracy theorists turns out to have been nearly as strange a visit by an alien spaceship. Long after the Cold War ended, observers continue to report a pattern of UFO activity near missile silos and other nuclear weapons sites. Perhaps it is not surprising that two subjects —nuclear war and alien invasion—should be linked.

Secret of Dark Matter –“Enormous Beacon and Planet-Sized Particles” 

SGR A*

 

 

“We tend to think about particles as being tiny but, theoretically, there is no reason they can’t be as big as a galaxy,” says Asimina Arvanitaki, The Aristarchus chair in theoretical physics at the Perimeter Institute for Theoretical Physics in Waterloo, Canada about solving the mystery of dark matter.

“Signals of Oxygen & Carbon” –Earliest Merging Galaxies

 

B14-65666 Earliest Merging Galaxies

 

Researchers using ALMA (Atacama Large Millimeter/submillimeter Array) observed signals of oxygen, carbon, and dust from a galaxy in the early Universe 13 billion years ago. This is the earliest galaxy where this useful combination of three signals has been detected. By comparing the different signals, the team determined that the galaxy is actually two galaxies merging together, making it the earliest example of merging galaxies yet discovered.
